Abstract

The invention relates to the technical field of cotton textiles and specifically relates to a modified cotton fiber and easy-care fabric prepared therefrom. A preparation method of the modified cottonfiber comprises the following steps: performing alkaline water dipping on cotton fibers with sodium hydroxide solution, bleaching the cotton fibers, pretreating the treated cotton fibers with organicsolution, and performing modifier treatment and centrifugal purification on the cotton fibers, wherein a cotton fiber modifier comprises titanium sulfate, urea, butyl titanate, sodium hydroxymethyl acrylamide and chitosan. The fabric prepared by mixing the modified cotton fibers, polypropylene fibers and chinlon is good in skin-friendly performance and also has air permeability and anti-wrinkle performance.

Description

technical field [0001] The invention relates to the technical field of cotton textiles, in particular to a modified cotton fiber and a non-ironing cloth prepared therefrom. Background technique [0002] Cotton is a plant that can provide natural plant fiber products. It is a crop with important strategic value. The cotton fiber in cotton has good toughness, high strength, excellent elasticity, chemical stability and moisture absorption performance. It is the best fabric fiber. Clothing made of cotton has good warmth retention, strong air permeability, and has excellent skin-friendly properties, making it very comfortable to wear. [0003] But cotton textiles also have its own shortcomings. For example, cotton textiles often shrink after rinsing due to the curling characteristics of the fiber itself. The shrunken cotton textiles need to be ironed. Nice, but re-wrinkled after multiple rinses. Contents of the invention [0004] Aiming at the problems existing in the prior a...
