DESCRIPTION
TITLE
GLOVE INTERMEDIATE MEMBRANE HAVING MOISTURE PERMEABILITY
AND WATERPROOF FUNCTIONS AND TO BE SIMULTANEOUSLY COUPLED
TO OUTER SHELL AND INNER LINER, GLOVES USING SAME, AND
MANUFACTURING METHOD THEREFOR
TECHNICAL FIELD
[0001] The present invention disclosed herein relates to sports gloves,
winter gloves,
waterproof gloves, or working safety gloves, and more particularly, to a glove
=
intermediate membrane having moisture peimeability and a waterproof function
and
simultaneously coupled to an outer shell and an inner liner, gloves using the
same, and a
manufacturing method therefor.
BACKGROUND ART
[0002] Winter gloves or waterproof gloves need a waterproof function
that prevents
the gloves from being wet from winter rain or water generated from melting
snow from
being introduced into hands of a user to warm the hands and, at the same time,
a moisture
permeable function that discharges sweat generated from the user's hands to
the outside
to give comfortable feeling.
[0003] The gloves are manufactured by using mainly a woven fabric or a
knitting
fabric. Hereinafter, the waterproof function and the moisture permeable
function of the
related art will be mainly described.
[0004] (1) Since the woven fabric does not have a contraction and expansion
property, a process of manufacturing gloves requires a complex cutting and
sewing
process to match a three-dimensional structure of fingers. A membrane made of
a
synthetic resin represented by Goretex is used as a membrane for giving the
waterproof
function and the moisture permeable function to the gloves made of the woven
fabric.
CA 02952912 2016-12-19

Unlike clothing, the gloves using the membrane include finger portions that
are too
narrow not to directly seal a sewing line with an adhesion tape or the like.
[0005] FIG. 1 illustrates the waterproof function and the moisture
permeable function
of conventional gloves in which the above-described intermediate membrane is
coupled
between an outer shell and an inner liner. According to FIG. 1, an
intermediate
membrane 20 is spaced apart from and coupled between an outer shell 30 and an
inner
liner 20. The gloves discharge sweat 3 generated from a skin 1 through the
inner liner
10, the intermediate membrane 20, and the outer shell 30. However, when water
2 is
introduced through the outer shell 30, although the intermediate membrane 20
blocks the
water 2 to prevent the skin 1 from being wet, a heat-retaining function is
sharply reduced
when the water is filled between the outer shell 30 and the intermediate
membrane 20 to
generate ice-formation 4.
[0006] FIG. 2 illustrates the waterproof function and the moisture
permeable function
of another conventional glove in which a coating layer is applied to an inner
surface of
the outer shell. A limitation regarding the waterproof function in FIG. 1 is
resolved by
applying a coating layer 32 to the inner surface of the outer shell 30.
However, although
the sweat 3 generated from the skin 1 is discharged through the intermediate
membrane
20, the discharging of the sweat 3 to the outside is blocked by the coating
layer 12 to
generate a limitation in the moisture permeable function. That is, the coating
layer 32
generates the limitation that is mutual conflict between the waterproof and
moisture
permeable functions, and thus it is required to resolve this limitation.
[0007] In particular, when the conventional gloves in FIGS. 1 and 2 are
used for
racing gloves that are used for downhill ski runs, a motorcycle, or the like,
which require
an accurate grip feeling, a gap is generated between the outer shell 30, the
intermediate
membrane 20, and the inner liner 10, which acts as one of factors that
decrease athletic
performance.
[0008] (2) Unlike the gloves made of the woven fabric, since the gloves
made of the
knitting fabric have an excellent contraction and expansion property, the
gloves may be
manufactured without a cutting or sewing process. Also, when the user wears
the
CA 02952912 2016-12-19
3
gloves, the hands are free to bend and extend due to the contraction and
expansion
property of the woven fabric. Thus, unlike the knitting fabric, the woven
fabric is
widely used for safety gloves or working gloves that are mass-produced at low
costs or
require a working property. However, the gloves have a fatal limitation that
is non-
waterproof
[0009] Although all or a portion of a surface of the gloves is dipped
into a synthetic
rubber solution such as latex to improve the waterproof property of the gloves
made of
the woven fabric, there is still a limitation in which sweat is not
discharged.
[0010] Meanwhile, special gloves used for an oil drilling work for
producing
petroleum or a shale gas production work on the sea need to prevent
introduction of
seawater or oil and simultaneously require the moisture permeable property and
the
excellent grip feeling. In particular, the special gloves are not waterproofed
when rains.
The conventional gloves do not meet the requirements.
[0011] The conventional gloves disclosed in Korean Patent Laid-Open
Application
No. 10-2013-0142042 are constituted by the inner liner and outer shell, which
are
manufactured by sewing, and a polymer film having a waterproof and windproof
property
and the moisture permeable property. Also, adhesion members for respectively
coupling
between ends of the finger portions of the inner liner and the intermediate
membrane and
between ends of finger portions of the intermediate membrane and the outer
shell are
provided. Here, each of the adhesion members includes a substrate, a hotmelt
adhesion
layer disposed on a top surface of the substrate, and an adhesion layer and a
hotmelt
adhesion layer, which are disposed on a bottom surface of the substrate while
disposed on
the same plane as each other. Each of the adhesion layers has a bottom surface
that is
disposed on an outer surface of the end of the finger portion of the inner
liner and an outer
surface of the end of the finger portion of the intermediate membrane.
[0012] In the conventional gloves constituted as above-described, the
adhesion
member is temporarily fixed to the outer surface of the inner liner, and then
the
intermediate membrane is disposed and permanently adhesion-fixed to the outer
surface
of the inner liner by hot pressing. Next, the adhesion member is temporarily
fixed to the
CA 02952912 2016-12-19
4
outer surface of the intermediate membrane, and then the outer shell is
disposed and
permanently adhesion-fixed to the outer surface of the intermediate membrane.
[0013] Accordingly, since two processes of temporarily fixing the
adhesion member
and two processes of hot pressing are required, the manufacturing process is
complex and
the manufacturing time increases. Also, as the adhesion member is temporarily
fixed to
one area of the inner liner and the intermediate membrane, a mutual adhesion
force
between the inner liner and the intermediate membrane is weak in an area to
which the
adhesion member is not fixed.
[0014] Thus, new gloves having the moisture permeable and waterproof
properties
and the excellent grip feeling need to be developed and a new method of easily
manufacturing the gloves with low costs is required.

MODE FOR CARRYING OUT THE INVENTION
[0036] Categories of the present invention are classified into a glove
intermediate
membrane, a manufacturing method for the glove intermediate membrane, and
gloves and
CA 02952912 2016-12-19
8
a manufacturing method therefor. Since all of the invention of each of the
categories
include the new glove intermediate membrane in common, which is inserted
between an
inner liner and an outer shell, the overall present invention corresponds to
one kind of
invention.
[0037]
Hereinafter, a basic constitution in accordance with the invention
corresponding to each of the categories will be described, and then an
embodiment of
each of the inventions will be described in detail.
[0038] 1. Glove intermediate membrane
[0039] A
basic constitution of the glove intermediate membrane in accordance with
the present invention includes first and second intermediate membranes that
are inserted
between the inner liner and the outer shell.
[0040] The
first intermediate membrane has a glove shape made of a first material
having moisture permeability and waterproof functions. Here,
the 'moisture
permeability' represents a function that discharges sweat generated from hands
to the
outside, and the 'waterproof functions' represent a function that prevents
water or
rainwater from being introduced into the inner liner. The first intermediate
membrane
may be made of a polyurethane-based material.
[0041] The
second intermediate membrane is disposed on one of an inner surface and
an outer surface of the first intermediate membrane and made of a second
material having
a melting point lower than that of the first material so that the first
intermediate
membrane is joined to one of the inner liner and the outer shell by heat
supply. The
second intermediate membrane has a glove shape. Here, the second intermediate
membrane is constituted by a sheet shaped fiber assembly made of a thermal
bonding
material and have a plurality of voids disposed over an entire surface thereof
Here, as a
gap between the voids is wider under a condition in which an adhesion force is
sufficiently maintained, it is more desirable to secure the permeability. The
second
intermediate membrane may be made of modified polyester and manufactured by
using a
non-woven fabric manufactured in the form of a web.
CA 02952912 2016-12-19

[0042] The above-described first intermediate membrane is constituted by
one pair of
sheets, each of which has a plane shape of a glove, a second intermediate
membrane is
constituted by one pair of sheets overlapping the inside or outside of the
first intermediate
membrane, and an edge part of each of the first and second intermediate
membranes
excluding a wrist portion includes an edge joining part that is joined by heat
supply.
Accordingly, the first and second intermediate membranes are integrated with
each other.
[0043] Hereinafter, first to third embodiments of the glove intermediate
membrane in
accordance with the present invention will be described in detail with
reference to the
drawings. A basic constitution of each of the embodiments is the same as
described
.. above. Hereinafter, a specific constitution of each of the embodiments will
be mainly
described.
[0044] As in FIGS. 3 and 4, a glove intermediate membrane 200 in
accordance with
the first embodiment further includes a third intermediate membrane 230
disposed on one
of an inner surface and an outer surface of the first intermediate membrane
210 besides
the above-described the first and second intermediate membranes 210 and 220.
The
third intermediate membrane 230 is made of a third material having a melting
point lower
than that of the first material of the first intermediate membrane 210 so that
the first
intermediate membrane 210 is joined to the other of the inner liner and the
outer shell of
the first intermediate membrane 210. Here, the third intermediate membrane 230
may
be made of the same material as that of the second intermediate membrane 220.
[0045] In detail, the first intermediate membrane 210 is constituted by
one pair of
sheets 211 and 212, each of which has a plane shape of a glove, the second
intermediate
membrane 220 is constituted by one pair of sheets 221 and 222 overlapping one
of the
inside and outside of the first intermediate membrane 210, and the third
intermediate
membrane 230 is constituted by one pair of sheets 231 and 232 overlapping the
other of
the inside and outside of the first intermediate membrane 210. Also, edge
parts of the
first, second and third intermediate membranes 210, 220, and 230 excluding
wrist
portions are joined by heat supply and integrated into an edge joining part
260.
CA 02952912 2016-12-19
[0046] As in FIG. 5, a glove intermediate membrane in accordance with
the second
embodiment includes a plurality of thermal joining materials 240 disposed over
the entire
inner surface of the first intermediate membrane 210 and made of a fourth
material
having a melting point lower than that of the first material of the first
intermediate
5 membrane 210 so that the first intermediate membrane 210 is joined to the
inner liner by
heat supply.
[0047] In detail, the first intermediate membrane 210 is constituted by
one pair of
sheets, each of which has the plane shape of the glove, and the second
intermediate
membrane 220 is constituted by one pair of sheets overlapping the outside of
the first
10 intermediate membrane 210. Also, the thermal joining materials 240 are
distributed in
the inner surface of the first intermediate membrane 210.
[0048] Also, the edge part of each of the first and second intermediate
membranes
210 and 220 excluding the wrist portion are joined by heat supply and
integrated into the
edge joining part 260.
[0049] The thermal joining materials 240 are uniformly spaced at a
predetermined
space over the entire inner surface of the first intermediate membrane 210 and
firmly
joined to the inner liner. For example, the thermal joining materials 240 may
be
respectively disposed on consecutive vertices of a rectangle or a hexagon
through a
printing method. Alternatively, the thermal joining materials 240 may be
uniformly
applied to the surface of the first intermediate membrane 210 through a spray
method.
These thermal joining materials 240 may use the same kind of material as the
first
material of the first intermediate membrane 210, which has a relatively low
melting point.
For example, when the first intermediate membrane 210 is made of a
polyurethane-based
material, each of the thermal joining materials 240 is also made of the same
polyurethane-
based material which has a relatively low melting point.
[0050] Meanwhile, although not shown in the drawings, unlike in FIG. 5,
the first
and second intermediate membranes 210 and 220 may replace their positions with
each
other, and the thermal joining material 240 may be disposed on the outer
surface of the
first intermediate membrane 210.
11
[0051] Alternatively, the glove intermediate membrane in FIG. 5 may be
turned
inside out to be used. Accordingly, the edge joining part 260 may be moved to
the
inside to make a clean outer surface and uniformly join the first intermediate
membrane
210 to the outer shell.
[0052] Although a glove intermediate membrane in accordance with the third
embodiment has a basic constitution that is the same as that of the second
embodiment,
each of a plurality of thermal joining tapes 250 having a viscosity is
disposed on a
position in which the thermal joining materials 240 is disposed. In detail, a
bottom
surface of the thermal joining tape 250 has a viscous material and is made of
a fifth
material having a melting point lower than that of the first material of the
first
intermediate membrane 210.
[0053] 2. Manufacturing method for glove intermediate membrane
[0054] As in FIG. 7, a manufacturing method for a glove intermediate
membrane in
accordance with the present invention includes a sheet arrangement process (S
1) of
.. overlapping the first and second intermediate membrane sheets that
basically constitute a
raw material, a sheet cutting process (S12) of cutting the overlappingly
arranged sheets in
the plane shape of the glove, and an edge joining process (S13) of joining the
edge part
excluding the wrist portion of the cut sheet.
[0055] In detail, the raw material in the sheet arrangement process
includes two first
.. intermediate membrane sheets made of the first material having moisture
permeability
and waterproof functions and two second intermediate membrane sheets made of
the
second material having a melting point lower than that of the first material
and disposed
one of the inside and outside of each of the two first intermediate membrane
sheets.
[0056] When the manufacturing method for the glove intermediate membrane
in
.. accordance with the first embodiment is described with reference to FIG. 4,
in the sheet
arrangement process, the two third intermediate membrane sheets 231 and 232
made of
the third material having a melting point lower than that of the first
material are further
CA 2952912 2019-02-21
CA 02952912 2016-12-19
12
overlappingly disposed on the inside of each of the two first intermediate
membrane
sheets 211 and 212.
[0057] When the manufacturing method for the glove intermediate membrane
in
accordance with the second embodiment is described with reference to FIG. 5,
in the
sheet arrangement process, a plurality of thermal joining materials made of
the fourth
material having a melting point lower than that of the first material are
disposed over the
entire inner surface of each of the two first intermediate membrane sheets
that are used in
the sheet arrangement process.
[0058] When the manufacturing method for the glove intermediate membrane
in
accordance with the third embodiment is described with reference to FIG. 6, a
plurality of
thermal joining tapes made of the fifth material having a melting point lower
than that of
the first material are attached to the entire inner surface of each of the two
first
intermediate membrane sheets that are used in the sheet arrangement process.
[0059] Since the above-described glove intermediate membrane may be
applied to
.. various kinds of gloves, an independent product sales market may be formed.
Also,
although the glove intermediate membrane is greater in size than the gloves,
since it is
joined while firmly contacting the inner liner or the outer shell of the
glove, it may be
used regardless of the size of gloves.
[0060] 3. Gloves
[0061] A glove in accordance with the present invention has a basic
constitution
including an inner liner having a glove shape; an outer shell surrounding the
inner liner; a
first intermediate membrane disposed between the inner liner and the outer
shell and
made of a first material having moisture permeability and waterproof
functions; and a
first joining part in which a second intermediate membrane made of a second
material
having a melting point lower than that of the first material and disposed on
one of an
inner surface and an outer surface of the first intermediate membrane allows
the first
intermediate membrane to join to one of the inner liner and the outer shell by
heat supply.
CA 02952912 2016-12-19
13
[0062] Hereinafter, fourth to sixth embodiments of the glove in
accordance with the
present invention will be described in detail. A basic constitution of each of
the
embodiments will be the same as described above. Hereinafter, a specific
constitution
of each of the embodiments will be mainly described. Attached FIGS. 8 to 10
are cross-
sectional views illustrating moisture permeability and waterproof functions
while wearing
the glove.
[0063] As in FIG. 8, a glove in accordance with the fourth embodiment
includes a
first joining part 261 in which a second intermediate membrane sheet disposed
on the
outer surface of the first intermediate membrane sheet 211 and made of the
second
material having a melting point lower than that of the first material allows
the first
intermediate membrane sheet to join to an outer shell 300 by heat supply.
Also, a
second joining part 262 in which a third intermediate membrane disposed on an
inner
surface of the first intermediate membrane sheet 211 and made of a third
material having
a melting point lower than that of the first material allows the first
intermediate
membrane sheet 211 to join to an inner liner 100 by heat supply is provided.
[0064] Accordingly, sweat 3 generated from a skin 1 is discharged to the
outside
sequentially through the inner liner 100, the second joining part 262, the
first intermediate
membrane sheet 211, the first joining part 261, and the outer shell 300. Also,
although
water 2 provided from the outside passes through the outer shell 300 and the
first joining
part 262, the water 2 may not pass through the first intermediate membrane
sheet 211
having moisture peinteability and waterproof functions and discharged to the
outside
again (refer to an arrow of a solid line). Here, since the first and second
joining parts
261 and 262 are formed of the second and third intermediate sheets 221 and 231
having a
plurality of voids by heat supply, the sweat 3 is smoothly discharged because
the first and
second joining parts 261 and 262 have enough voids (refer to an arrow of a
dotted line).
[0065] Also, since the inner liner 100, the glove intermediate membrane
200, and the
outer shell 300 are firmly joined while closely contacting each other,
excellent grip
feeling is provided.
14
[0066] As in FIG. 9, a glove in accordance with the fifth embodiment
includes a first
joining part 261 having the same constitution as that in the fourth embodiment
and a third
joining part 263 in which a plurality of thermal joining materials, which are
disposed over
the entire inner surface of the first intermediate membrane sheet 211 and made
of a fourth
material having a melting point lower than that of the first material, allows
the first
intermediate membrane sheet 211 to joint to the inner liner 100 by heat
supply.
[0067] Accordingly, the sweat 3 generated from the skin 1 is discharged
to a gap
disposed in the third joining part 263. That is, the sweat 3 is discharged
through a space
disposed between portions in which the plurality of thermal joining materials
240
illustrated in FIG. 5 are thermally bonded.
[0068] As in FIG. 10, a glove in accordance with the sixth embodiment
includes a
first joining part 261 having the same constitution as that in the fourth
embodiment and a
fourth joining part 264 in which a plurality of thermal joining tapes, which
are attached to
the inner surface of the first intermediate membrane sheet 211 and made of a
fifth
material having a melting point lower than that of the first material, allows
the first
intermediate membrane sheet 211 to joint to the inner liner 100 by heat
supply.
[0069] Accordingly, the sweat 3 generated from the skin 1 is discharged
to a gap
disposed in the fourth joining part 264. That is, the sweat 3 is discharged
through a
space disposed between portions in which a plurality of thermal joining tapes
250
illustrated in FIG. 6 are thermally bonded.
[0070] 4. Manufacturing method for glove
[0071] A manufacturing method for the glove in accordance with the
present
invention includes sequentially stacking the inner liner disposed on the mold,
the glove
intermediate membrane in accordance with one of the first to third
embodiments, and the
outer shell, joining by heat-supply, and then separating the glove from the
mold.
[0072] As in FIGS. 11 and 12, a manufacturing method in accordance with
a seventh
embodiment includes an inner liner coupling process (S21) in which the inner
liner 100 is
CA 2952912 2019-02-21
15
put onto a mold M having a glove shape; an intermediate membrane coupling
process
(S22) in which the above-described glove intermediate membrane 200 is put onto
the
inner liner 100; an outer shell coupling process (S23) in which the outer
shell 300 is put
onto the glove intermediate membrane 200; and a thermal bonding process (S24)
in
.. which the inner liner 100, the glove intermediate membrane 200, and the
outer shell 300
are stacked and joined through at least one of a method for supplying heat
from the
outside of the outer shell 300 and a method for supplying heat from the mold
M. After
these series of processes are completed, the gloves are separated from the
mold M to
complete the glove manufacturing.
[0073] As in FIG. 12, the mold M used for manufacturing the glove has the
glove
shape in which fingers are sufficiently spaced and is made of a metallic
material. It is
desired that the mold M maintains a shape in which a thumb to a little finger
have
vertically standing shape so that the inner liner 100, the glove intermediate
membrane
200, and the outer shell 300 are easily put thereon. Also, finger portions of
the mold M,
especially root portions of the fingers, are sufficiently spaced so that all
of the inner liner
100, the glove intermediate membrane 200, and the outer shell 300 are
uniformly joined.
[0074] In the inner liner or outer shell coupling process, the inner
liner 100 and the
outer shell 300 are made of a knitting fabric, and the inner liner 100 and the
outer shell
300 are expanded to be put onto the mold M in each of the processes. When the
glove
intermediate membrane 200 is thermally joined while put onto the inner liner
100 or the
outer shell 300, although a user excessively moves hands while wearing the
glove, the
glove intermediate membrane 200 may be prevented from being separated from the
inner
liner 100 or the outer shell 300 and damaged.
[0075] In the thermal bonding process, heat is supplied from the outside
or the mold
M to a surface of the outer shell to form the first to fourth joining parts
261 to 264
between each of the inner liner 100, the glove intermediate membrane 200, and
the outer
shell 300 as in FIGS. 8 to 10.
[0076] Here, an oven or an air-heating furnace providing hot air may be
used as a
heating device, and the surface of the outer shell 300 is pressurized in the
heating process

to uniformly thermal-bond and simultaneously decrease process time.
Especially, when
the outer shell 300 is made of a woven fabric, since a gap may be generated
between the
sewing line portion and the intermediate membrane 200, it is desired to
pressurize the
sewing line portion.
[0077] It is desired that power is supplied in the thermal bonding process
and the
previous process thereof to maintain the mold M at a predetermined temperature
or more.
Accordingly, the thermal bonding time may decrease, and also the glove
intermediate
membrane 200 is uniformly thermal-bonded to the entire inner surface of the
outer shell
300.
[0078] As in FIGS. 13 and 14, a manufacturing method for a glove in
accordance
with an eighth embodiment includes an inner liner coupling process (S31), a
thermal
bonding tape attaching process (S32), an intermediate membrane coupling
process (S33),
an outer shell coupling process (S34) and a thermal bonding process (S35).
Although the
eighth embodiment is basically the same as that of the seventh embodiment, is
different in
that, after the inner liner coupling process (S31), a plurality of thermal
bonding tapes 250
are attached to the outer surface of the inner liner 100, and then the glove
intermediate
membrane excluding the thermal bonding tape 250 from the constitution of the
glove
intermediate membrane in accordance with the third embodiment in FIG. 6 is
used. That
is, the second intermediate membrane 220 constituting the glove intermediate
membrane
is disposed to the outer surface of the first intermediate membrane 210. Here,
the
thermal bonding tape 250 is made of a fifth material having a melting point
lower than
that of the first material of the first intermediate membrane.
[0079] The above-disclosed subject matter is to be considered
illustrative, and not
restrictive, and the appended claims are intended to cover all such
modifications,
enhancements, and other embodiments, which fall within the true spirit and
scope of the
present invention. Thus, to the maximum extent allowed by law, the scope of
the
present invention is to be determined by the broadest permissible
interpretation of the
following claims and their equivalents, and shall not be restricted or limited
by the
foregoing detailed description.
