Abstract

The invention relates to spandex composite fibers. The spandex composite fibers are added with silver fibers and bamboo charcoal fibers as auxiliary raw material. The ratio of mass portion between of main raw material and auxiliary raw material is 5.5 to 7:1. The preparation method of spandex composite fibers comprises following steps of: firstly, carrying out surface treatment to aramid fibers; secondly, producing blended yarns by employing aramid fibers, polyurethane fibers and bamboo charcoal fibers in a conventional method; thirdly, weaving into fabric and making clothes by adoption of a conventional method. The produced clothes are worn comfortably and feel soft and have anti-bacterial and odor-resistant functions and are low in cost.

Description

technical field [0001] The invention relates to the field of polymer fibers, and in particular designs a spandex composite fiber and a preparation method thereof. Background technique [0002] Spandex is the abbreviation of polyurethane fiber, which is a kind of elastic fiber. Spandex is generally composed of multiple filaments, generally 10D / filament, and now there are 15D / filament, or even 20D / filament. It is generally not used alone, but mixed into fabrics in small amounts. This kind of fiber has both rubber properties and fiber properties. Most of them are used for core-spun yarns with spandex as the core yarn, called elastic core-spun yarns. The main characteristics of this yarn are that it can obtain good feel and appearance, The outer fiber composed of natural fibers has good hygroscopicity; the second is that only 1-10% spandex filament can be used to produce high-quality elastic yarn; the third is that the elastic percentage control ranges from 10% to 20%, which c...
