Description

Single-sided hydrophilic single-sided waterproof fabric Technical Field The application relates to the field of fabrics, in particular to a single-sided hydrophilic single-sided waterproof fabric. Background The current single-sided hydrophilic single-sided waterproof fabric is mainly applied to the fields of sportswear, outdoor clothing and the like, but the prior art has the problem of balance between hydrophilicity and waterproofness. When the inner layer of the fabric is made of a high-hydrophilicity material, sweat can be absorbed rapidly, but moisture is easy to penetrate into the outer layer to form obvious sweat stain marks, otherwise, if the outer layer is subjected to heavy waterproof treatment, the moisture absorption effect of the inner layer is inhibited, and the wearing comfort is reduced. In the traditional process, a double-layer fabric composite structure is mostly adopted, but the problems of thickness increase and air permeability reduction exist. The partial single-layer structure is treated by the after-finishing coating, but the coating cracking easily occurs to cause insufficient durability, and the finishing process has obvious influence on the moisture absorption performance of the hydrophilic layer. In the existing woven structure, the blending of the hydrophobic fiber and the hydrophilic fiber easily causes the disorder of capillary effect, the directional moisture conduction is impossible, and the unidirectional transmission of the moisture management effect is difficult to realize. Therefore, there is a need for a fabric that realizes moisture absorption of the inner layer and perspiration prevention of the outer layer through structural optimization. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a single-sided hydrophilic single-sided waterproof fabric. The sweat stain prevention effect of the inner layer moisture absorption and the outer layer of the fabric can be realized.
