Description

Method for manufacturing yarn containing chitosan for weaving fibers {Method of weaving thread with chitosan}

The present invention relates to a method for producing yarn containing chitosan for weaving fibers, and more particularly, to weave various types of yarn by weaving natural fibers, chemical fibers, regenerated fibers, etc., which are usually manufactured to weave yarn. The present invention relates to a chitosan fiber and a chemically modified chitosan fiber of Patent Application No. 99-17502 previously filed by the present applicant, and to a yarn manufacturing method containing chitosan prepared by the method for producing the same.

In general, most garments are made of natural or chemical fibers, and the general process for making these garments is to buy yarn, weave the fabric, and then use a lye to reduce and shrink. And dye first.

And after printing the pattern which has a predetermined pattern, it washes with water. By the way, the dye used in this printing process uses chemical dyes harmful to a human body, and urea, hydrochloric acid, etc. which are harmful to a human body are used also in a water washing process.

When the printed fabric is dried, packaged and shipped, the clothing manufacturer purchases the fabric, cuts the fabric into a predetermined form, sews and irons the fabric in a predetermined form, and determines whether the product is abnormal. Only products without these are shipped to the market.

In addition, most of conventional clothes do not radiate far infrared rays and do not have antibacterial effect, so if you keep wearing them, sweat, fat, dust and germs will be produced by breeding germs based on sweat, and various skin diseases will be caused. Cotton type is acid-treated due to the weakening of the fiber, and heaves quickly.

In general, products that take up a lot of weight in daily life such as clothing, socks, and bandages that are woven with a mixture of cotton, wool, silk, and acrylic such as natural fibers, recycled fibers, artificial fibers, and chemical fibers, or blended with each other Everyone is using it.

However, in modern society, the environmental pollution according to the living environment has reached the extreme due to the outflow and pollution of the waste water, and these things are causing the disease, which makes people's health worse.

In addition, many of the necessities of life such as clothing and socks are used by those who are harmful to the human body such as man-made fibers or chemical fibers, so those who have a lot of sweating jobs or have skin diseases and other illnesses Eggplant disease was caused or worsened.

The present invention has been made in order to solve the above problems, the object of which is to make a yarn from chitosan prepared by the applicant of the present applicant and to the chitosan natural fibers such as cotton, wool, silk or recycled fibers, artificial fibers, chemical Chitosan fiber is a biofunctional material that can be used as a medical, veterinary and plant wound healing agent by mixing and blending with fibers, etc., with superior antimicrobial properties, high dyeing resistance to direct dyes and reactive dyes, and excellent sweat and antistatic properties. It is to provide a yarn manufacturing method containing chitosan for weaving fibers that can relieve discomfort and harm the skin of the human body to help promote health.

Therefore, as shown in patent application No. 99-17502, which is previously filed for producing a yarn according to the present invention, chitosan fibers are produced by directly spinning chitosan into an aqueous solution of an alkali mixture, whereby the chitosan solution is spun directly into an alkaline aqueous solution. The chitosan fiber comprised from 100% chitosan obtained by this is provided.

In addition, several aldehydes are used to provide chemical modification of chitosan fibers to provide N-alkylidene and N-arylidene chitosan fibers.

Also provided are methods of making chitosan fibers and modified chitosan fibers.

In the chitosan fibers produced by the above method, the present invention is to weave chitosan fibers into chitosan yarns using a yarn manufacturing method that is commonly used, and also to the chitosan fibers, such as natural fibers, chemical fibers, recycled fibers, It is to contain a fiber to produce a yarn.

Looking at another embodiment of the present invention as follows.

Example 1

In order to weave various types of yarn using a conventionally used yarn manufacturing method, cotton is mixed or blended with the chitosan fibers to weave the yarn.

Example 2

It is characterized by weaving the yarn by mixing cotton and polyester to the chitosan fiber using a conventionally used yarn manufacturing method.

Example 3

It is characterized by weaving a yarn by mixing polyester to chitosan fibers using a conventionally used yarn manufacturing method.

Example 4

The yarn is woven by blending acryl and wool on the chitosan fibers, and by mixing acryl and cotton on the chitosan fibers using a conventional yarn manufacturing method.

Example 5

Using a conventional yarn manufacturing method, the silk is blended with the chitosan fibers, and the wool is mixed with the chitosan fibers to weave the yarns.

Example 6

It is characterized by blending polyester and wool in chitosan fibers and blending polyester and silk in chitosan fibers using conventional yarn manufacturing methods.

Chitin according to the present invention is a high value-added biopolymer that is commercially extracted from shellfish of crustaceans as the next most abundant natural polymer material on earth. Since such chitin is water insoluble, it is a major obstacle in utilization. Therefore, by deacetylating chitin to obtain chitosan, it can be converted into chitosan, in which water solubility is expressed in weakly acidic liquid, and such water-soluble chitosan is industrially used more useful than chitin.

Since chitin and chitosan are poorly soluble in general solvents, it is difficult to prepare them into a solution, and thus, little has been developed so far regarding the production of molded articles such as fibers and films that can be obtained by the wet method. It may be said that the industrial application of chitin and chitosan is delayed compared with the wide use of cellulose because of such poor solubility.

Typically, as described above, the garment is made of yarn in a state in which various fibers are mixed or mixed with each other, and the garment is made by weaving the cloth with the yarn, and the general textile material does not absorb sweat or sweat caused by sweat because it is not antibacterial. The odor is caused by the production of clothing such as chitosan yarn in the state of weaving chitosan yarn with chitosan fibers as described above, so that chitosan absorbs sweat and thus sweat is absorbed by chitosan.

In addition, the chitosan is excellent in antimicrobial activity and can revitalize the skin cells of the human body to prevent eczema and other dermatitis that may be caused by sweat in advance to produce a garment such as chitosan containing yarn Wearing it has features that can be prevented from various diseases that occur on the skin.

In addition, when the chitosan yarn is manufactured, the chitosan fiber is mixed with or mixed with various kinds of natural fibers and chemical fibers such as cotton, polyester, acrylic, and the like to produce clothing. It can achieve the effect according to.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, weaving chitosan yarn in a conventional manufacturing method according to the present invention and weaving the yarn, such as natural fibers, chemical fibers, regenerated fibers, and the like by weaving the yarn to prevent the antistatic and the smell of sweat is generated due to sweat It is a very useful invention that can relieve the discomfort and at the same time prevent the occurrence of the disease has an excellent effect on maintaining and promoting health.
