PROCEDE DE CONSERVATION SANITAIRE DE FIBRES DU LIBER ET ADDITIF SPECIAL DE CONSERVATION SANITAIRE POUR FIBRES DE JUTE UTILISE DANS CE PROCEDEDE

THE PROCESS FOR HEALTH PRESERVING BAST FIBRES AND THE JUTE FIBRE SPECIFIC HEALTH PRESERVING ASSISTANT USED IN THE SAME

Abrégé français

L'invention porte sur un procédé de conservation sanitaire de fibres de chanvre, qui comprend les étapes suivantes consistant à : (1) pulvériser l'additif préparé sur les fibres de chanvre, le rapport en poids entre l'additif et les fribres de chanvre étant de 0,4 à 0,5; (2) introduire les fibres de chanvre traitées à l'étape (1) dans le premier entrepôt de conservation sanitaire et les y laisser pendant 2 à 3 jours; (3) retirer du premier entrepôt de conservation sanitaire les fibres de chanvre améliorées à l'étape (2), les retourner, puis les placer dans le deuxième entrepôt de conservation sanitaire. Une fois que la température est proche de 50-60°C, les conserver pendant 5 à 6 jours dans l'entrepôt de conservation sanitaire. Le procédé de conservation sanitaire permet à l'additif de mieux pénétrer dans l'âme interne des fibres de chanvre, avec pour effet d'améliorer efficacement l'aptitude au filage des fibres. De plus, l'invention porte sur un additif spécial de conservation sanitaire utilisé dans le procédé de conservation sanitaire précité. Cet additif de conservation sanitaire permet d'améliorer l'humidité et la souplesse des fibres, tout en garantissant la blancheur appropriée des fibres.

PROCESS FOR HEALTH-PRESERVING HEMP AND SPECIAL
HEALTH-PRESERVING ADDITIVE IN JUTE FIBRE USED THEREIN
Technical Field
The invention relates to the fibre assistant field, in particular relates to a
process for
health preserving bast fibres and a jute fibre specific health preserving
assistant used in the
same.
Background
With the rising of human material living standards, more and more people begin
to move
their attention from the durability of clothing to the comfort of clothing.
Due to the good
moisture absorption, air permeability, low static and good antibacterial
properties of bast
fibre, bast fabrics have gained more and more popularity with people. The
existing bast
fabrics mainly refer to the linen, ramie or the combination obtained through
blended
spinning or interweaving said materials with other fibres such as cotton,
wool, chemical
fibres, or silk, etc. However, as linen and ramie are expensive, the bast
fabrics are not widely
used. Jute fibre is one of the most widely used cellulose fibres and only
follows cotton fibre
in the world. Jute is cheap in price and has better moisture absorption and
drapability than
linen and ramie, and its antibacterial ability just follows that of hemp, so
that it has great
application value and developmental potential. However, the lignin content in
jute is quite
high (up to 10-13%), which is several times higher than that in linen, and
jute fibre is very
thick and hard, and with poor spinnability, restraining the use of jute in
fabrics. In the
existing technology, in order to improve the spinnability of said fibres, the
nature fibres must
be firstly degummed and thinned. However, although the fibres are degummed and
thinned,
the fibres still remain hard, and are difficult to be spun. Therefore, it is
necessary to improve
the fibre traits of the bast fibres that are degummed and thinned.
Nowadays, the ordinary process for improving the fibre traits of bast fibres
is to health
