Problems solved by technology

[0002] After the pure cotton woven fabric is finished by the existing easy ironing finishing process, it feels obviously hard and itchy. However, the resin finishing agent will destroy the fibers of the fabric while fully cross-linking with the fabric, resulting in a decrease in the softness and smoothness of the fabric, a hard hand feel, and a tingling sensation when worn.
[0003] At the same time, most of the resin finishing agents used in the existing easy-ironing finishing process are synthesized by formaldehyde, so the formaldehyde content of the fabrics made by it is relatively high (generally 20-120ppm), which is harmful to the human body during wearing. bad health

Abstract

The invention provides a formaldehyde-free easy-ironing and finishing method for a pure cotton woven fabric. The method comprises the following steps: pretreatment of singeing and desizing; alkali mercerization treatment, wherein the concentration of alkali liquor is 20-28 baume degrees, and the treatment time is 45-60 seconds; liquid ammonia mercerization treatment; crosslinking treatment: performing crosslinking treatment on the fabric by adopting a ternary copolymerization softener; washing and shaping treatment; pre-shrinking treatment; obtaining a pure cotton woven fabric finished product. With the adoption of the technical scheme provided by the invention, the obtained pure cotton woven fabric not only has a good luster effect; but also has obvious body bone and good resilience, is soft and rich in hand feeling and good in crease-resisting effect.

technical field [0001] The invention relates to a formaldehyde-free easy ironing finishing method for pure cotton woven fabrics, belonging to the technical field of textiles. Background technique [0002] After the pure cotton woven fabric is finished by the existing easy ironing finishing process, it feels obviously hard and itchy. However, the resin finishing agent will destroy the fibers of the fabric when the cross-linking reaction occurs fully with the fabric, thereby causing the softness and smoothness of the fabric to decrease, the hand feeling is hard, and there is a tingling sensation when worn. [0003] At the same time, most of the resin finishing agents used in the existing easy-ironing finishing process are synthesized by formaldehyde, so the formaldehyde content of the fabrics made by it is relatively high (generally 20-120ppm), which is harmful to the human body during wearing. Bad health. [0004] In view of the above problems, it is an urgent technical pro...
