Problems solved by technology

At the same time, the calcination process will cause the surface silver ions to transform into zero-valent state
These factors lead to a decrease in antimicrobial capacity and thus waste
[0006] The process of preparing antibacterial polyester fibers using silver-based antibacterial agents is difficult and the steps are cumbersome

Embodiment 1

[0041] S2: raw material processing. The raw materials are selected to include 500 parts of dimethyl terephthalate, 500 parts of propylene glycol and 500 parts by weight.

[0042] S3: heating and melting. The material processed by S2 is transported into the reactor, and the temperature in the reactor is

[0044] S4: spinning. The material processed by the metering pump is transported to the spinneret, and it continues to rush towards the spinneret.

[0045] S5: cooling and forming. The filaments ejected from the spinneret were blown by an air conditioner, and the air temperature was maintained at 25°C.

[0046] S6: oiling. The material after S5 treatment is transported to the oil tank containing oil to soak for 85min.

[0047] S7: winding bundle. The spun fibers after the S6 treatment are wound and bundled.

[0048] S8: Curl cut. The material processed by S7 is transported to the crimping machine for crimping, and the

Abstract

The present invention relates to the field of manufacturing raw chemical fibers, and discloses a preparation process of antibacterial raw polyester staple fibers, which includes the following steps: S1: preparation of antibacterial masterbatch; raw materials of antibacterial masterbatch include dimethyl octadecane in parts by weight 50-70 parts of [3-(trimethoxysilyl)propyl]ammonium chloride, 20-40 parts of arachidyl alcohol propionate, 120-150 parts of dimethyl terephthalate, 70-90 parts of propylene glycol and Dispersant 170‑230 parts; S2: raw material processing; S3: heating and melting; S4: spinning; S5: cooling forming; S6: oiling; Virgin polyester staple fiber. By selecting dimethyloctadecyl[3‑(trimethoxysilyl)propyl]ammonium chloride and adding it to the carrier formed by dimethyl terephthalate and propylene glycol together with the dispersant, it can be prepared as a homogeneous Antibacterial masterbatch, easy to obtain and easy to operate. At the same time, the problems of hard agglomeration and poor compatibility can be avoided.

Description

A kind of preparation technology of antibacterial virgin polyester staple fiber technical field The present invention relates to the manufacture field of virgin chemical fiber, more specifically, it relates to a kind of antibacterial virgin polyester short fiber Fiber preparation process. Background technique Primary polyester fiber is a kind of obtained through polycondensation reaction using terephthalic acid and derivatives thereof and ethylene glycol. Widely used chemical fiber, modified fiber has high breaking strength and elastic modulus, excellent heat setting, good heat resistance and light resistance, is One of the fastest growing varieties of synthetic fibers. The molecular arrangement of polyester fiber is regular and compact, and the degree of crystallinity and orientation is high, but Because of the lack of dyeable groups, it is difficult to dye polyester fibers, and the equipment requirements for dyeing are relatively high. Problems are more difficul...
