Description
Technical Field
The invention relates to the field of functional fabrics, and particularly relates to a preparation method of a modified polyester-nylon fabric.
Background
Because of its excellent physical and chemical properties, polyester fibers are widely used in textile industry and other industries. However, the polyester fiber has a smooth surface and no hydrophilic group on a macromolecular chain, so that the antistatic property, the hydrophilicity and the wearability of the polyester fiber are poor. Improving the hydrophilicity of the polyester fiber is a main way to improve the antistatic performance and the wearability of the polyester fiber. The alkali decrement can not only greatly improve the hydrophilic performance of the polyester fiber, but also increase the softness and drapability of the fiber, but the environment is seriously polluted by using a large amount of alkali.
Many methods for improving the hydrophilicity of the polyester fiber comprise a physical modification method, a chemical modification method and the like. Generally, the chemical modification method is to graft hydrophilic agents such as acrylic acid, chitosan, polyethylene glycol and the like onto the polyester fiber to improve the hydrophilic performance of the polyester fiber. Among these chemical agents, chitosan is a hydrophilic agent which is very environmentally friendly and has good properties. The chitosan molecule contains a large amount of amino and hydroxyl, has good biocompatibility and degradability, also has good hemostatic and anti-inflammatory effects, and is widely applied in many fields. However, the molecular weight of chitosan is hundreds of thousands to millions, so that the chitosan is insoluble in water and only soluble in dilute acid, and the application of the chitosan is limited. The molecular weight of the chitosan is reduced, so that the hydrophilic effect of the chitosan can be improved, and certain performances which are not possessed by the high molecular weight chitosan can be endowed.
Allantoin, the main ingredient of snail mucus, helps skin regeneration and repair, and is a natural antioxidant for slowing down the aging process of human skin. For the snail, when the shell and the soft body part are damaged by external beating, the allantoin has the functions of diminishing inflammation and repairing to the snail, and the important function of body regeneration is completed; collagen is an important component of skin connective tissue, maintains the formation of intact skin together with elastin, is used as a humectant in beauty care products, and has the effect of keeping moisture; elastin, a tissue protein that keeps the skin elastic, when the skin loses elasticity as people age, the phenomenon of wrinkles will occur correspondingly, proper supplementation of elastin can prevent skin wrinkles from appearing in advance, and can reduce the damage of ultraviolet rays to the skin. At present, most of snail mucus is used in the field of cosmetics, but as a protein similar to silk fibroin, silk fibroin finished fabrics have been widely applied in the field of textile fabrics, and at present, no application is provided for the snail mucus finished fabrics.
