Embodiment Construction

[0020] A kind of antibacterial polyethylene terephthalate fiber, firstly, adding nano-scale 3-6% in the synthesis of polyester to obtain nano-modified polyester, polyester can be directly obtained nano-modified by melt spinning process Polyethylene terephthalate filament.

[0021] Implementation example:

[0022] 1. The synthesis of polyester is at first catalyst solution configuration: the present invention uses p-toluenesulfonic acid and titanium isopropoxide as catalyst, first determines the consumption of ethylene glycol, then adds catalyst to the catalyst configuration container, and the addition of p-toluenesulfonic acid The amount is 100×10 of the amount of ethylene glycol -6 , the amount of titanium isopropoxide added is 300×10 of the amount of ethylene glycol -6 , inject a small amount of ethylene glycol, stir and heat to dissolve the catalyst in ethylene glycol at 100°C, the dissolved ethylene glycol catalyst solution enters the dilution container, and inject the r...

Abstract

The invention relates to the field of polyester filament preparation, in particular to a 3D warp-knitted spacer fabric prepared from antibacterial polyester filaments, which is characterized by being prepared by the following steps of: adding 0.5 to 1 percent of nano-scale silver-loaded zirconium phosphate in the process of synthesizing polyethylene terephthalate to obtain nano-modified polyester; and directly performing a melt spinning process to obtain antibacterial polyethylene terephthalate filaments, and weaving the prepared filaments by using a double tricot machine. The 3D warp-knitted spacer fabric is mainly applied to 3D mattresses, infant mattresses, pillow inners, fillers of auto seat cushions, sofa and other high-grade soft furniture, medical protective articles, air conditioner filter systems and other fields, and the products have excellent properties such as nontoxicity, long-term self-cleaning property, low possibility of sinking, good air permeability and the like.

Description

technical field [0001] The invention relates to the field of preparation of polyester filaments, in particular to a 3D warp-knitted spacer fabric made of antibacterial polyester filaments. Background technique [0002] With the improvement of people's living standards, the requirements for daily necessities are getting higher and higher. The original products are difficult to meet people's needs. Various new materials are being continuously developed and applied. The unique advantages have created the functionalization, comfort and high-grade of the new materials. The new materials have many advantages, and of course the added value created is also high. [0003] Among them, the new polyester polyethylene terephthalate can be processed into 3D warp-knitted spacer fabrics through chemically synthesized filaments, which has broad application prospects and can be used to replace sponges and felts in traditional mattresses, sofas and other upholstered furniture. Filling, change...
