Preparation process of antibacterial polyester fiber fabric

Abstract

The invention discloses a preparation process of an antibacterial polyester fiber fabric, which relates to the technical field of clothing fabrics. The preparation process of the antibacterial polyester fiber fabric comprises the following steps: grinding tourmaline in the presence of a dispersant to obtain a tourmaline powder; mixing the tourmaline powder with titanium dioxide and then adding toa maleic anhydride solution to carry out a grafting reaction to obtain a grafted tourmaline mixed powder; adding the mixed powder of grafted tourmaline powder in the process of polyester synthesis toobtain composite polyester; performing melt spinning on the composite polyester to obtain a polyester fiber; and weaving the polyester fiber to obtain the polyester fiber fabric. According to the preparation process of the antibacterial polyester fiber fabric provided by the invention, after the polyester fabric clothing contacts a human body, the generated negative ions enter the human body through the respiratory tract and enter the blood through the alveolar epithelial layer, thereby increasing blood oxygen content and lung capacity.

Description

technical field

[0001] The invention belongs to the technical field of apparel fabrics, in particular to a preparation process for antibacterial polyester fiber fabrics. Background technique

[0002] Fabrics are commonly used textile substrates in daily life and work. There are many types, including high-temperature resistant fabrics, corrosion-resistant fabrics, shading fabrics, UV-resistant fabrics, antibacterial fabrics, etc., which are used in different fields according to their performance characteristics.

[0003] Polyester fiber fabrics are widely used in existing synthetic fibers. What people usually call polyester fiber refers to polyethylene terephthalate (PET) fiber, which is composed of polyethylene terephthalic acid and polyethylene Polyester chips formed by diol polycondensation are spun, and the final fiber is an ideal textile raw material. Its elastic property is close to that of wool, and because of the high rigidity of the macromolecular chain in the fiber...
