Abstract

The invention relates to a method for preparing a moisture-absorbing and quick-drying fabric. First, the fully-drawn yarn of the textured yarn is prepared: in the process of preparing a round skin-core composite fiber from high-viscosity PET and low-viscosity PET according to the FDY process, the spinneret The spinneret hole of the spinneret is changed from circular to trilobal, and the ring blowing is used to cool it, and the arrangement of the trilobal spinneret on the spinneret is controlled to meet certain conditions, and the relaxation heat treatment is carried out to obtain the fully drawn yarn of the textured yarn; Cotton fiber and textured yarn full-drawn silk are used as raw materials for processing. The processing process is: knitting on the machine → pre-setting → pre-treatment → dyeing → soft treatment → open-width setting; : Water absorption ≥ 250%, drip diffusion time ≤ 1.9 seconds, wicking height ≥ 142mm; quick-drying: evaporation rate ≥ 0.38g / h. The invention effectively solves the problem of increasing the moisture-conducting performance of fibers without using functional finishing, and improving the moisture-absorbing and quick-drying performance of fabrics as a whole.

Description

technical field [0001] The invention belongs to the technical field and relates to a method for preparing a moisture-absorbing and quick-drying fabric. Background technique [0002] Traditional knitted fabrics are generally woven with cotton or blended with other cellulose fibers. Cellulose fibers have good hygroscopicity. When the human body sweats a lot, it can quickly absorb the moisture on the surface of the human body, but the moisture that enters the fiber It is difficult to evaporate, because the hydrophilicity of cellulose fibers is too strong, and the migration resistance of water in the fibers is relatively large. After absorbing water on the side close to the skin, it cannot quickly reach the outside, so it cannot evaporate quickly; in addition, after absorbing water The friction between the cellulose fibers becomes larger, and the stretchability of the fabric decreases when wearing, which will lead to poor wearing experience. [0003] In the prior art, a double-...
