Problems solved by technology

[0004] Acrylic yarn is the raw material of textile yarn. Acrylic yarn is mainly acrylonitrile fiber, the acrylonitrile content is greater than 85%, and the hardness is relatively high. It needs to be improved by adding a soft and smooth agent with high amine value, but because acrylic yarn Containing a large amount of strong anionic groups, a large amount of softening agent gathers on the surface of the fiber, it is difficult to reach the inside of the acrylic fiber yarn, and it is also difficult to absorb evenly, so it is difficult to handle. In this regard, the invention provides a soft and smooth fabric for acrylic fiber yarn. agent to solve the above problems

Abstract

The invention provides a softening and smoothing agent for acrylic yarns and a preparation method of the softening and smoothing agent. The softening and smoothing agent comprises a compound as shown in a structural formula 1, alcohol ether carboxylate, betaine, isomeric alcohol ether, an octadecylamine surfactant and water. The compound shown in the structural formula 1 is shown in the specification, in the structural formula 1, R1 is equal to-CH2CH2CH2NHCH2CH2NH2NH2, R2 is equal to- N > = 100. In the structural formula 1, R1 and R2 can greatly increase the amino density and increase the amine value, and can soften rigid polyacrylonitrile, so that the fabric obtains good softness and smoothness. The softening and smoothing agent is weak or moderate in ionicity, can permeate and migrate into the acrylic yarn under the synergistic effect of the alcohol ether carboxylate, the betaine, the isomeric alcohol ether and the octadecylamine surfactant, effectively adsorbs acrylonitrile in the acrylic yarn, improves the softness of the acrylic yarn, and endows the acrylic yarn with good hand feeling.

Description

Technical field [0001] The present invention relates to the field of acrylic yarn processing, and more particularly to a soft lane and a preparation method thereof for acrylic yarns. Background technique [0002] Acrylic is one of the three major synthetic fibers of the world. It has the characteristics of bright color, soft feel, light, warm, anti-mite, and its performance is approximately wool, and the price is only 20% ~ 30% of wool, and the welcome of consumers . The appearance of acrylic appearance is white, curled, fluffy, soft, like wool, mostly used with wool blend or as a wool, so it is called "synthetic wool". [0003] Acrylic is the product name of polyacrylonitrile fibers in our country. Acrylic is very unique in the interior, an irregular spiral conformation, and there is no strict crystallization zone, but high order arrangement is arranged in low sequence. Since this structure has good thermal elastic (can be processed), the acrylic density is small, which is small...
