Method for preparing mask base cloth

Abstract

The invention provides a method for preparing a mask base cloth. The method for preparing the mask base cloth comprises the steps that the preparation of a modified fiber and the preparation of a blended fiber base cloth are carried out, specifically, according to the preparation of the modified fiber, an unsaturated amino acid modified viscose fiber is adopted, specifically, 0.01-0.3 part, by weight, of an emulsifier and a 0.015-0.5 part, by weight, of a pH regulator are added in 100 parts, by weight, of water, then 10-30 parts, by weight, of the viscose fiber is added, under nitrogen atmosphere, 0.01-0.1 part, by weight, of an initiator is added, then unsaturated amino acid is added, 0.01-1 part, by weight, of a chain transfer agent is added after the reaction is started, and amino acidmodified viscose fiber is obtained by washing and drying after the reaction. The mask base cloth solves the problem that the improvement of mechanical properties reduces the bonding degree and liquidretention rate of the base cloth, so that the base cloth has excellent mechanical properties, meanwhile, the flexural rigidity of the base cloth is reduced, and the flexural rigidity is as low as 0.0132gf.cm<2> / cm, the flexibility is good, the bonding degree of the base cloth to the skin is improved, and the liquid retention rate of the base cloth is improved and can reach 2702%.

Description

technical field [0001] The invention relates to a preparation method of a facial mask base cloth, in particular to a preparation method of a modified blended spunlace facial mask base cloth. Background technique [0002] Facial mask is a skin care product popular among beauty lovers because of its convenient portability and obvious effect. Masks can be divided into carrier-free masks and carrier-based masks according to the way of use. The latter refers to a mask that uses film-forming materials or fiber materials (ie, mask base fabric) as a carrier and supplemented with nutrients to apply to the face. At present, the best-selling mask in the market is the mask base fabric as the carrier. Common mask base fabric materials mainly include non-woven fabrics, silk, conceptual invisible silk, hydrogel, pure cotton fiber, biological fiber, and viscose fiber. , Tencel and bamboo charcoal fiber. The market claims that the difference in the function of the stick-on mask mainly depe...

AI Technical Summary

Problems solved by technology

The base fabric of a general facial mask can only play the role of preserving the nutrient solution, lacks functional groups, and has poor functionality, resulting in poor compatibility with the skin

[0003] When viscose fiber is used to prepare the base fabric, the strength is low. Due to the action of water during the stretching process of the base fabric in a wet state, the mechanical properties such as strength and elongation at break are seriously reduced, and it is easy to be damaged. Therefore, blending is used to increase the base fabric. strength and elongation at break, but at the same time it will increase the flexural rigidity of the base fabric, make its softness worse, and make it less compatible with the facial skin, so that the mask and its preserved nutrient solution cannot effectively act on the skin and exert its full potential.
