Abstract

The invention relates to the technical field of household textiles, in particular to a preparation method of an acrylic and polyester fiber blended yarn. The method comprises the following steps of (1) performing polyester modification treatment: adding persulfate, N,N-dimethylformamide and acrylamide into water, uniformly stirring to prepare a solution, then putting polyester fibers into the solution, carrying out a grafting reaction under the ultrasonic action in a nitrogen atmosphere, and then carrying out washing and drying to obtain modified polyester; and (2) mixing the modified polyester obtained in the step (1) with acrylic fibers, and spinning a mixture into the blended yarn through open-end spinning. Hydrophilic groups are grafted to the polyester fibers through the grafting reaction, so that the hygroscopicity of polyester is improved; and the modified polyester and the acrylic fibers are blended to prepare the yarn, so that the hygroscopicity and softness of the acrylic and polyester blended yarn can be further improved. A textile prepared from the blended yarn is good in hygroscopicity and softness.

Description

technical field [0001] The invention relates to the technical field of household textiles, in particular to an acrylic polyester fiber blended yarn and a preparation method thereof. Background technique [0002] Acrylic fiber, also known as polyacrylonitrile fiber, is a synthetic fiber processed from polyacrylonitrile as the main monomer (the monomer content accounts for more than 85%), and its main repeating unit is -CH 2 CH(CN)-. [0003] The appearance, feel, elasticity and warmth of acrylic fiber are similar to that of wool. In addition, acrylic fiber is brightly dyed, light-resistant, heat-resistant, acid-resistant, oxidant-resistant, organic solvent-resistant, mildew-proof, moth-proof, aging-resistant, easy to wash and dry , and light weight (second only to polypropylene), it is an important raw material for sweaters, warm clothing and other fabrics. [0004] However, the wear resistance of acrylic fiber is not good, which is the worst wear resistance among synthetic...
