Problems solved by technology

[0003] However, the internal molecules of polyester are closely arranged, and there is no hydrophilic structure between the molecules, so the moisture regain is very small and the hygroscopicity is poor.
Due to the poor hygroscopicity and antistatic property of polyester, the air permeability of polyester fabric is not good, and the dyeability and pilling resistance are poor.

Abstract

The application relates to the technical field of textile fabrics and provides multifunctional polyester fiber and a preparation method thereof. The multifunctional polyester fiber has a skin-core structure including a skin layer and a core layer, wherein the skin layer is a polyester layer; and the core layer is a PET layer containing a liquid-crystal material with color change when in a wet condition and titanium dioxide. The invention also provides an application of the fiber, i.e., provides a fabric with the functions of preventing accidental exposure and warning a wet condition; the weaving material of the fabric includes the multifunctional polyester fiber. By adopting the multifunctional polyester fiber provided by adopting the application, the functions of preventing accidental exposure and warning the wet condition of the textile fabrics can be realized, and the practicability is wide.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a multifunctional polyester fiber, its preparation method and application. Background technique [0002] Polyester is an important variety of chemical synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation. —— Polyethylene terephthalate (PET), which is then spun and processed into fibers. Polyester fiber is a hydrophobic fiber with a tight structure. It has good physical and chemical properties such as high strength, good elasticity, good shape retention, and high dimensional stability. The clothes woven from it are durable, good electrical insulation, and easy to wear. Washing and drying quickly, it has the reputation of "washable and wearable", so it is wi...
