Wig fiber resistant to high temperature and easy to dye

Abstract

The invention mainly relates to the technical field of man-made fiber processing, and discloses a wig fiber resistant to high temperature and easy to dye. The wig fiber is prepared from the followingraw materials: 40-45 parts of chitosan, 11-13 parts of an epoxy resin and 4-6 parts of graphene. The wig fiber resistant to high temperature and easy to dye is soft and silky, similar to real hair, resistant to high temperature, free of deformation or burning when used at high temperatures and easy to color during dyeing, and is capable of increasing the practicability of wig; sodium selenate solution is added into the chitosan, vacuum rotation is carried out after gradual heating, and UV intermittent irradiation is carried out to promote the combination of selenium and chitosan amino group, and finally freeze-drying is carried out to remove excess water and powder the block chitosan, so as to increase the combination ability of the amino group and the selenium, increase the stability of the modified chitosan and increase the flexibility and cohesiveness of the chitosan; and during the dyeing, the chitosan can be fully bound with dyeing solution, so as to improve the color fastness ofthe wig and enable the wig fiber to besoft, silky and similar to real hair.

Description

technical field [0001] The invention mainly relates to the technical field of artificial fiber processing, in particular to a wig fiber resistant to high temperature and easy to dye. Background technique [0002] Wigs can play a good decorative role, you can change different hairstyles at any time, and can avoid damage to real hair caused by frequent hot dyeing, and can save a lot of time and cost; most of the wigs are prepared after treatment of real hair At present, it is difficult to purchase real hair, and the purchase price is high, which limits the production of wigs, so artificial fibers are gradually used instead of real hair, but most artificial fiber wigs are easy to deform and burn when exposed to high temperatures, and produce unpleasant smell Smell, and after a few washes it becomes very frizzy and hard to manage.

[0002] Wigs can play a good decorative role, you can change different hairstyles at any time, and can avoid damage to real hair caused by frequent hot dyeing, and can save a lot of time and cost; most of the wigs are prepared after treatment of real hair At present, it is difficult to purchase real hair, and the purchase price is high, which limits the production of wigs, so artificial fibers are gradually used instead of real hair, but most artificial fiber wigs are easy to deform and burn when exposed to high temperatures, and produce unpleasant smell Smells and gets very frizzy and hard to manage after a few washes

[0003] The existing patent document CN 101713107 A discloses a high-temperature flame-retardant fiber for wigs, which is prepared by using a copolyester containing polyalkylene terephthalate or polyalkylene terephthalate as the main body. One or more of them can increase the strength and heat resistance of the wig, but the prepared hardness is too large, the softness and smoothness are poor, and when the wig is dyed, the coloring property is too poor; the patent document CN 102926025 A disclosed A method for preparing artificial wig fibers, which uses Antarctic krill shrimp meat protein and sodium alginate as raw materials to prepare artificial wig fibers by blending and spinning. Shrimp powder is stirred and dissolved in 2-4% lye for 5-7 hours, cooled to 35-40°C, filtered, and the filtrate is collected to obtain Antarctic krill shrimp meat protein solution; ②Add sodium alginate to the mixture of water-titanium dioxide solution, stirred at room temperature for 20-30 minutes to completely dissolve sodium alginate to obtain sodium alginate solution; ③ mix Antarctic krill shrimp meat protein solution and sodium alginate solution, stir evenly, and defoam to obtain sodium alginate- Antarctic krill and shrimp meat protein spinning solution", but the document "Fiber-grade sodium alginate raw material and spinning effect analysis, Xu Wen" disclosed "1.2.3 The structure and properties of sodium alginate (4) Sodium alginate is not resistant Strong acid and strong alkali, sodium alginate will be converted into alginic acid and precipitated in strong acid, and sodium alginate will be significantly degraded in a strong alkaline environment." According to the "sodium hydroxide concentration and pH comparison table", 2% sodium hydroxide The pH of the solution is 13.7, the pH of 3% sodium hydroxide solution is 13.88, and the pH of 4% sodium hydroxide solution is 14, which is extremely alkaline. Therefore, the strong alkalinity of Antarctic krill shrimp meat protein solution will obviously affect sodium alginate. cause degradation, the resulting wig has low strength, and is prone to breakage during use, which obviously shortens the service life of the wig; The thermal decomposition process of sodium alginate fiber (b) is similar and can basically be divided into 4 parts

The first step occurs between 30-200°C, mainly due to the volatilization of free water on the surface of the fiber and the loss of bound water in the fiber accompanied by the breaking process of some glycosidic bonds. water, and the glycosidic bond breaks, although the wig will lose water and decompose, it will not cause an open flame, but it still loses its usability
