Problems solved by technology

The composite nano-components of inorganic and organic matter are complex, and the implementation of the method requires modification of the original textile pretreatment equipment; in addition, in order to improve the affinity and durability of nano-zinc oxide and fabrics, the adhesive acrylate The addition of will affect the fabric style and feel worse
Another example is the disclosed functionalized nano-chitosan and nano-titanium dioxide modified tussah silk fabric of CN102677465A, which plays an anti-ultraviolet effect by nano-titanium dioxide, and improves the cross-linking fixation of chitosan and tussah silk fabric by organic polyacids, effectively improving and enhancing Tussah silk fabrics have comprehensive properties such as anti-wrinkle, softness, anti-bacterial, anti-shrinkage, self-cleaning, anti-ultraviolet, and dye adsorption efficiency, but the dispersion system of the finishing agent is also relatively complicated, and the preparation of nano-scale composite dispersion finishing liquid is cumbersome. High requirements on the stability of its dispersion system

Abstract

The invention provides a modified-chitosan-containing anti-ultraviolet finishing agent for cotton fabric and anti-ultraviolet cotton fabric obtained by aid of the anti-ultraviolet finishing agent. The modified-chitosan-containing anti-ultraviolet finishing agent for the cotton fabric is a uniformly mixed solution of 3,4,5-trimethoxybenzoyl chitosan, a crosslinking agent, a penetrant and an acetic acid or lactic acid solution, wherein the crosslinking agent is organic polycarboxylic acid or amino-modified silicone oil emulsion; the penetrant is either JFC or peregal O. The anti-ultraviolet cotton fabric with anti-ultraviolet, anti-bacterial and anti-crease finishing functions is obtained through double-dip double-nip, water washing and drying, the anti-ultraviolet, anti-bacterial and anti-crease finishing functions are high in durability, the cotton fabric still maintains the original style of the fabric after finishing, the hand feel, the strength, the whiteness and the color of the cotton fabric are not affected, and the original human body affinity is maintained; the finishing agent is simple in composition and easy to prepare, and a finishing process is simple and environment-friendly.

Description

technical field [0001] The application of the present invention relates to a fabric anti-ultraviolet finishing agent and its finished fabric, especially relates to a modified chitosan anti-ultraviolet finishing agent and its finished cotton fabric. Background technique [0002] Chitosan is a natural polysaccharide polymer material with rich sources, safety, non-toxicity and good biodegradability. At present, the application of chitosan and its derivatives in the functional finishing of textiles is mainly limited to antibacterial, anti-mildew and anti-wrinkle aspects. Such as the modified chitosan-modified nano-silver antibacterial composite material prepared by patent CN104128602A, the chitosan and nano-silver synergistically exert antibacterial effect. [0003] There are two main categories of textile anti-ultraviolet finishing agents, one is anti-ultraviolet shielding agent, which reduces the transmittance of ultraviolet light by means of reflection, refraction or scatter...
