Preparation method of multifunctional polyester fiber

Abstract

The invention discloses a preparation method of multifunctional polyester fiber. The method comprises the following steps of: A) adding equal sepiolite, nanotube halloysite and tourmaline into water, and stirring for reaction; B) adding an acrylic acid solution, a polyethylene glycol solution, an ammonium persulfate solution and deionized water into the system of the step A), and stirring for reaction; C) cooling the mixture formed in the step B) to room temperature to form viscous liquid, drying at 110-120 DEG C, and grinding to obtain multifunctional modified material with particle size not greater than 2 microns; and D) adding the multifunctional modified material obtained in the step C) into polyester melt, uniformly stirring, and spinning with a '+'-shaped profile hole spinneret plate to obtain the multifunctional polyester fiber. The method disclosed by the invention has the advantages that: the prepared polyester fiber has high water absorption property; due to the microporous and special-shaped fiber structure, the polyester fiber has high air permeability and moisture absorption property, and the human body feels comfortable; and the multifunctional polyester fiber can permanently release negative oxygen ions, thereby being good for health.

Description

technical field [0001] The invention relates to a textile technology method, in particular to a method for manufacturing multifunctional polyester fibers. Background technique [0002] Polyester fiber has a large output and a wide range of uses. Its strength, abrasion resistance, resilience and dimensional stability can better meet the needs of various end uses. However, polyester fiber is a typical hydrophobic fiber with a moisture absorption rate of only 0.4%. As a material for wearing next to the skin, its wearing comfort is very poor, especially when the human body sweats, it is difficult to perspire, which makes people feel hot and uncomfortable. Feel. At the same time, polyester fiber has poor hygroscopicity, which also brings a series of problems to weaving, such as easy to accumulate static electricity, easy to absorb dust, and difficult to remove oil stains. Therefore, since the industrialization of polyester fiber, research on the modification of polyester fiber ...
