CONSTRUCTION OF AND METHOD OF CONSTRUCTING
A PROTECTIVE AND EFFECTIVE GRIPPING GLOVE OR OTHER GARMENT
FIELD OF THE INVENTION
100011 The invention relates to a protective and effective grip glove, sleeve
or other
garment. In particular, the invention is directed to a novel yarn construction
that,
when made and used in accordance with the present invention, would provide a
cut resistant glove or other knit item having also effective grip
characteristics
even in moisture intensive environments.
BACKGROUND
[0002] Industrial safety focuses on protection of a worker from a variety of
dangers,
including cuts and abrasions from handling of items in process. While hand and
arm protection is critical, injury to other body parts is also of concern.
Thus,
protective garments such as gloves, sleeves, arm bands, vests, coats,
leggings,
pants and other garments are used to provide protection in a variety of work
environments. Such items must be both strong and flexible to be effective. For
example, gloves may be used to protect a worker from handling cold or hot
items.
Gloves may also be used to protect a worker from sharp or abrasive items. A
particularly difficult environment is a bottling plant, which routinely
requires a
worker to handle a variety of potentially dangerous work in process such as
glass,
aluminum, in addition to operating the machinery that is used in the
processing of
such work materials. A bottling plant involves yet further danger in that much
of

CA 02666598 2009-04-16
WO 2008/057205 PCT/US2007/022436
the material may be wet due to the nature of such processes. Workers wearing
gloves in such a moisture intensive environment need not only protection from
punctures, cuts and abrasions, but also, an effective grip that guards against
slippage or mishandling of wet, often sharp, work materials.
[0003] A variety of work gloves have been used in such environments in the
past. String
knit gloves are a more recent garment that are growing in popularity. Such
garments, and more particularly gloves, provide a desired flexibility and
protection from both heat and cold. As a result, string knit gloves are
replacing
older work gloves made of canvas, leather or jersey. Further, string knit
gloves
have a multitude of uses ranging from a jogging glove to manufacturing and
package handling gloves.
[0004] String knit gloves may be made using various fibers. The introduction
of aramids
such as KEVLARTM brand fiber and other aramid fibers has proven effective
against cuts, punctures and other abrasions. String knit gloves may also be
made
using SpectraTM brand polyethylene and even steel fibers. Moreover, to address
grip ability and product life, PVC dot and brick patterns have been used on
the
palm.
[0005] Even so, string knit gloves and other garments may be improved. One
recognized
problem with protective string knit gloves and garments is that the fibers,
especially the SpectraTM fiber, can still be slippery. Since these gloves are
routinely used in food processing, glass handling, automobile manufacture,
metal
stamping and other hazardous work environments, there is substantial use of
such
ATL_IMANAGE-4274535 v3 2
CA 02666598 2009-04-16
WO 2008/057205 PCT/US2007/022436
gloves. Moreover, these environments and other such manufacturing facilities
involve a variety of fluids. This causes the gloves or other garments to
become
even more slippery. The problem is so acute that it has been suggested to
users
that they place a disposable latex glove over the knit glove to improve
gripping
ability. Of course, sliding a latex glove on over a knit glove is difficult to
accomplish and awkward in use. As to other garments, such as sleeves and the
like, the suggestion has no application and the problem persists.
[0006] The art has attempted to address the slippage and grip problem by the
use of PVC
dots that may be placed about the palm of fingers of a glove. However, there
is a
need in the art for garments, specifically gloves that provide more direct and
comprehensive gripping ability in the context of a string knit glove. One
response
in the art is to apply or coat the glove or gloves with PVC in order to
enhance
gripping ability.
[0007] There is a further need in the art for gloves and other garments,
including but not
limited to sleeves, armbands, and protective apparel that enjoy the benefits
of a
cut resistant knit having enhanced, more comprehensive gripping ability.
[0008] There is a further need in the art for a yarn construction that
provides the
fundamental element for constructing string knit garments, including gloves,
to
protect a user and provide enhanced gripping ability.
[0009] There is a yet further need in the art for a knit glove and other
garments that
provide not only cut resistance but also gripping ability even in moisture
intense
work environments.

[00010] These and other features, objects and advantages of the present
invention will be
seen and understood by those of ordinary skill in the art upon reading this
application in conjunction with the associated drawings.
SUMMARY OF THE INVENTION
[00011] The present invention, and the various embodiments thereof, addresses
the above
issues, both independently and separately, to provide novel yarn constructions
from which a variety of garments can be produced. The present description,
therefore, supports and discloses but does not limit the invention.
[00012] A cut-resistant and effective gripping ability glove has been
developed comprised
of a novel yarn construction. Those of ordinary skill will appreciate that the
disclosed yarn construction has application well beyond that of a glove,
including
but not limited to sleeves, arm bands, vests, coats, pants, leggings and other
clothing items. The invention is disclosed in the form of a glove, but also
embodied in any other garment, having the following yarn constructions: (1) a
string knit glove formed with fibers of cotton and high-density polyethylene;
and
(2) a sting knit glove formed with fibers of cotton, steel and fiberglass. In
each
instance, the cotton string is exposed to provide comprehensive and wet grip
ability. Of course, many other garments may be made of these yarn
constructions.
[00013] The use of a cotton string not only provides for gripping of wet or
moist objects,
but also provides a cost benefit. It is known that gloves (or sleeves or other
garments) with superior cut resistance are made from yarns that cost
substantially
more than the materials of the present invention. Moreover, it has been found
that
ATL_IMANAGE-4274535 v3 4
CA 02666598 2009-04-16
WO 2008/057205 PCT/US2007/022436
gloves made of the second yarn has significantly enhanced cut resistance when
compared to a glove made of aramid fibers of the same weight.
1000141 Described somewhat more particularly, the present invention is
embodied in a
glove made with a unique combination of materials that provides effective
gripping ability for a user. For example, the invention includes a cut
resistant and
comprehensive gripping ability glove made with a composite yarn having a
cotton
string or fiber comprising approximately 5 to 85 percent of the composite yarn
by
weight, and a high-density polyethylene string or fiber comprising 5 to 85
percent
of the composite yarn by weight. Another embodiment of the present invention
is
a glove made with a composite yarn having a cotton string or fiber comprising
approximately 20 to 84 percent of the composite yarn by weight, a steel string
or
fiber comprising approximately 8 to 45 percent of the composite yarn by
weight,
and a fiberglass string or fiber comprising approximately 8 to 45 percent of
the
composite yarn by weight. Yet another embodiment of the present invention is a
glove made from composite yarn having a cotton string or fiber comprising
approximately 70 percent of the composite yarn by weight, a steel string or
fiber
comprising approximately 15 percent of the composite yarn by weight, and a
fiberglass string or fiber comprising approximately 15 percent of the
composite
yarn by weight. In each of these embodiments, it is to be understood that the
cotton string or fiber is exposed so as to contact an item to be handled. By
use of
the cotton fiber, the glove is able to contact the item more comprehensively
than
would PVC dots or the like. Instead, the cotton fiber is able to make contact
with
ATL-IMANAGE-4274535 0 5
CA 02666598 2009-04-16
WO 2008/057205 PCT/US2007/022436
an object to be secured at all points where the user makes contact with the
object,
as opposed to just those points at which a PVC dot or the like is found.
[00015] It will be appreciated by those of skill in the art that the elemental
yarns described
herein may be used to manufacture a variety of garments. In fact, while the
present invention has specific application to cut-resistant and enhanced
gripping
ability gloves, sleeves and the like, it has application to any garment or
product
that may be constructed in accordance with the invention. Thus, any fabric,
garment or other product manufactured with a composite yarn having either
cotton and high-density polyethylene or cotton, steel and fiberglass is made
in
accordance with the present invention. Thus, the present invention includes:
1000161 a composite yarn as described herein having fibers of cotton and high-
density
polyethylene, or fibers of cotton, steel and fiberglass; a method of
manufacturing
such composite yarns for the construction of garments such as a glove; and a
method of manufacturing a cut resistant and enhanced gripping ability fabric
for
use in the manufacture of a glove, garment or other item such as protective
apparel or the like.
[00017] Objects, features and advantages of various systems, methods, and
articles of
manufacture according to various embodiments of the invention include:
[00018] Systems for providing cut resistant fabrics and garments having a
composite yarn
with either cotton and polyethylene or cotton, steel and fiberglass with the
cotton
string exposed, such as a glove;
