Problems solved by technology

[0003] The polyester fiber is in contact with the human body and the charged body, and it is easy to generate static electricity. In addition, in order to improve the decorative and other functions of the polyester fiber fabric, some flame retardant ingredients are usually added to the polyester fiber, but the commonly used flame retardant ingredients are generally It is a reactive flame retardant component. When in contact with the human body, it will cause a certain degree of damage to the human body and cause an allergic reaction. In addition, the added components put forward higher requirements for the quality control of polyester fiber

Abstract

The invention discloses a preparation method of an allergy-free polyester fiber. The preparation method includes the following steps: 1, mixing components, and melting at 250-300 DEG C to obtain melt; 2, spinning the melt in the step 1 to enable the melt to flow out, and cooling a dissolved system to 20-30 DEG C; and 3, winding the cooled system in the step 2 to obtain the allergy-free polyester fiber. According to the method, one or more of poly(ethylene furandicarboxylate), polylactic acid ester and polybutylene terephthalate are used as a matrix, and the antimonous trioxide is added, so that the polyester fiber has fiber strength and density, and can effectively avoid causing human skin sensitivity.

Description

technical field [0001] The invention belongs to the field of fiber technology, and in particular relates to a preparation method of hypoallergenic polyester fiber. Background technique [0002] Polyester fiber refers to the synthetic fiber obtained by spinning the polyester formed by polycondensation of organic dibasic acid and dibasic alcohol, which belongs to the polymer compound. The common polyester fiber generally refers to polyethylene terephthalate, which is polymerized from terephthalic acid and ethylene glycol, and is currently widely used in many fields such as clothing, cloth, and fillers. [0003] The polyester fiber is in contact with the human body and the charged body, and it is easy to generate static electricity. In addition, in order to improve the decorative and other functions of the polyester fiber fabric, some flame retardant ingredients are usually added to the polyester fiber, but the commonly used flame retardant ingredients are generally It is a re...
