Problems solved by technology

However, due to the loose yarn structure and non-uniform supramolecular structure of polyester network filaments, after the fabric is subjected to friction, the fibers are easy to break, slide out of the fabric surface and entangle with each other into balls, resulting in the pilling performance and wear resistance of the fabric. Poor sex

Abstract

The invention provides a preparation method of linen-like fibers. The preparation method comprises the following steps of S1, preparing a cellulose solution; S2, preparing aged cellulose fibers from the cellulose solution in the step S1; S3, preparing cellulose microspheres; S4, preparing cellulose microspheres of which the surfaces are acetylated; S5, grinding polyester slices into powder, addingthe cellulose microspheres subjected to surface acetylation into the polyester powder according to a certain mass ratio, uniformly mixing, adding into a screw extruder, extruding, and granulating toobtain modified regenerated polyester master batch; and S6, melting the modified regenerated polyester master batch prepared in the step S5 into a spinning solution, and carrying out spinning througha melt spinning machine to prepare polyester fibers. According to the linen-like fibers provided by the invention, the polyester fibers with a linen-like bamboo joint effect is obtained by combining polyester and cellulose microspheres, controlling the spinning diameter and directly taking cellulose as the microspheres.

Description

technical field [0001] The invention relates to the field of functional fibers, in particular to a method for preparing hemp-like fibers. Background technique [0002] Polyester linen-like fabric is favored by consumers because of its unique style characteristics. Hemp fabric is popular for its rough and natural appearance, as well as antibacterial, moisture-wicking and other properties. However, pure hemp fiber has a high stiffness and itching feeling, and the garment is easy to wrinkle. Therefore, various hemp-like fibers have emerged as the times require. Linen-like products can be divided into linen-like appearance and linen-like performance. The linen-like process can be started from four aspects: raw materials, spinning technology, weaving, and finishing. In terms of appearance, certain effects can be achieved from the aspects of weave, spinning process and finishing, such as crepe weave, slub yarn, wrinkle treatment, etc.; Linear density and other aspects to achiev...
