The present invention relates to a polysaccharide antimicrobial deodorant blend yarn and to fabrics and textiles made thereof, and more particularly, to an excellent antimicrobial deodorization and washing resistance using polysaccharide fibers containing silver (Ag) metal fine particles. It relates to a polysaccharide antimicrobial deodorant blend yarn imparted to the properties and to fabrics and textiles made therefrom.

Textile products such as blankets, pads, sofas, carpets, and other clothing products such as infant goods, socks, and underwear are used to breed various bacteria and dust mites such as Staphylococcus aureus and pneumococcus, and various diseases, atopic dermatitis, It causes allergic dermatitis and creates an environment that is harmful to health. In particular, these bacteria and ticks can be a serious threat to health for infants, children and the elderly. Moreover, the bodies and excreta of house dust mites are known to cause atopic dermatitis or allergic dermatitis, and are known to have a physically eliminated method.

Meanwhile, chitosan is a natural polymer obtained by deacetylating chitin extracted from crustaceans such as crabs and shrimps, and is known as a natural antibacterial agent that is harmless to humans. According to US Patent No. 3,533,940, chitosan can be prepared from chitin, and US Patent No. 5,114,788. No. discloses a method of making a fabric in which a solution containing chitosan is immersed in a cotton fabric.

However, the sterilization effect of silver and its effectiveness have to solve some problems in order to apply well known facts or sterilization power to textile products.

Japanese Patent Application Laid-Open No. 54-38951 discloses a method of preparing an ion exchange copolymer and treating the fiber with an aqueous silver salt solution to impart antimicrobial properties. However, conventional techniques generally use silver or chitosan powder. As a method of spinning by mixing in a solution or a melt, a method of treating fibers or films using a method of padding or coating is known. In addition, in the case of using silver electrolyzed water in clothes and drying it or immersing it in silver fine particle solution, it is difficult to maintain the effect due to the dropping out of laundry, and in order to prevent the fall of silver, a coating agent is used in the fiber. However, this causes a result of covering the silver with a coating agent has a problem that is difficult to express the antimicrobial activity of the silver.

The present invention is conceived to solve the problems of the prior art as described above, the object of the present invention is to combine the advantages of silver (우수한) with excellent antimicrobial and antimicrobial and human-friendly chitosan polymer combined synergistic effect It is to provide a polysaccharide antimicrobial deodorant blend yarn to achieve and excellent laundry durability.

Do. If the size of the particles is less than 1nm, it is difficult to produce the fine particles. If the size of the particles exceeds 100nm, it is not good to reduce the radioactivity due to reaggregation of particles, non-uniform dispersibility, weak bonding force, nozzle clogging, and the like.

In the present invention, a polysaccharide of chitin or chitosan is used as a fiber-forming substance. In particular, it is preferable to use chitosan polymer powder having a deacetylation degree of 75% or more and molecular weight of 100,000 to 2,000,000 from which inorganic salts and proteins are removed. The chitosan powder can be dissolved in an acidic solution. The acid in the acidic solution is preferably an organic acid such as acetic acid, lactic acid, formic acid, glycolic acid, acrylic acid, succinic acid, gluconic acid, tartaric acid, maleic acid, citric acid, glutamic acid, and more. good. It is preferable to use distilled water, pure water, deionized water, and the like, and the chitosan may be chitin.

The antimicrobial deodorant blend yarn of the present invention is a first step of producing polysaccharide filament fiber containing silver (Ag) metal fine particles 5 to 20 crimps per inch and cut into lengths of 20 to 100 mm to make short fibers. After mixing 1 to 50% by weight of fibers and 50 to 99% by weight of short fibers of general fibers, the second process is followed by a normal blended yarn manufacturing process consisting of a carding, carding, regular cotton, and spinning process.

In the polysaccharide fiber, if the number of crimp is less than 5 / in difficult to blend even due to the slip phenomenon when blended with other fibers, it is difficult to uniformly cut the fiber due to physical damage of the fiber when more than 20 / / This deteriorates and adversely affects the blending process. In addition, if the length of the short fiber is less than 20mm, the fiber length is too short and tends to drift and move around between the rollers in the draft process, which is driven to the outer side of the yarn or to catch and increase the fiber bundle. If it exceeds 100mm, it does not mix uniformly with other fibers and is driven to the center of the spinning yarn or cut between rollers in the drafting process, which is also a cause of disinfectant.

As the general fibers, all fibers such as natural fibers such as cotton, hemp, wool, and silk, regenerated fibers such as rayon and lyocell, and synthetic fibers such as nylon, polyester, and acrylic may be employed according to purposes and uses. will be.
