Abstract

The present invention relates to a method for preparing moisture-absorbent and quick-drying fabric. The method comprises: preparing fully-drawn yarn of textured yarn: in the process of preparing the round sheath-core composite fiber from high-viscosity PET and low-viscosity PET according to the FDD process, changing spinneret holes from circular to trilobal, performing cooling by using cross air blow, controlling the arrangement of the trilobal spinneret holes on a spinneret plate to meet certain conditions, and performing relaxation heat treatment to obtain the fully-drawn yarn of the textured yarn; and taking the cotton fiber and the fully-drawn yarn of the textured yarn as the raw materials for processing, wherein the processing process is: weaving on the machine, finalizing the designin advance, performing pre-treatment, performing dyeing, performing soft treatment, and performing scutching and setting. The prepared moisture-absorbent and quick-drying fabric has the moisture absorption that: a water absorption rate is greater than or equal to 250%, a drip diffusion time is less than or equal to 1.9 seconds, and a wicking height is greater than or equal to 142mm; and the quick-drying performance that: a evaporation rate is greater than or equal to 0.38g / h. According to the method provided by the present invention, the problem of increasing the moisture conductivity of thefiber without using functional finishing is solved, and the moisture absorption and quick-drying performance of the fabric can be improved 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-...
