[0027] The invention discloses a preparation method of antibacterial PVC polyester coated yarn, which mainly comprises two steps of preparing a masterbatch and coating the masterbatch with polyester yarn.

[0028] The preparation of color masterbatch comprises the following steps:

[0029] a, in parts by mass, weigh each component raw material;

[0030] b. Put the raw materials of each component into the high-speed mixer for high-speed mixing;

[0031] c. After stirring and cooling to 50 degrees, transfer to the hopper, and the hopper is sent into the main engine hopper through the conveying device;

[0032] d. Cut into particles by a granulator, that is, masterbatch.

[0033] The speed of high-speed mixing is 700-800 rpm.

[0034] The steps of polyester filament coating masterbatch are:

[0035] a. The filaments are put into the filament frame, passed through the tensioner positioning device into the mold, and the mold is loaded into the shunt

[0036] b. Put the masterb...

Abstract

The invention relates to a preparation method of an antibacterial PVC polyester coated filament. The method consists of: 1) color masterbatch preparation: weighing the following raw materials; putting the raw materials into a high-speed mixer to conduct high speed mixing; carrying out stirring cooling to 50DEG C, then transferring the mixture into a hopper, and sending the hopper into a host hopper by a conveying device; cutting the mixture into particles by a pelletizer, thus obtaining color masterbatch; 2) coating: putting polyester filament into a filament rack, penetrating a mold by a tensioner positioning device, and mounting the mold into a diverter; adding the color masterbatch into a hopper, carrying out heating plasticizing, then bringing the color masterbatch to the diverter by a host motor; letting a traction disc drive the polyester filament to perform coating through the diverter; and conducting cooling with cooling water, then bringing the filament into an automation line, performing detection, and then conducting rolling-up. The carrier resin with polyvinyl chloride as the color masterbatch is added with an antibacterial nano material, the polyester filament is colored, and is also endowed with good antibacterial properties. The stiffness handfeel of the polyester filament is enhanced, and the finishing process of additional application of a stiffening agent in a follow-up processing process of polyester window decorations can be eliminated.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial PVC polyester coated yarn, which belongs to the field of coated yarns of synthetic fiber filaments. Background technique [0002] At present, the output of polyester fiber in my country exceeds 10 million tons, one third of which needs to be dyed. The dye dyeing method will discharge 40 million tons of colored sewage every year. The light fastness of dyeing, washing, perspiration, sublimation, etc. The fastness is far lower than that of pre-spinning coloring, and has not adapted to the needs of social development and improvement of people's living standards. Pre-spinning coloring of polyester is a new technology that melts or disperses color masterbatch in polyester spinning stock solution for melt spinning to directly produce colored polyester fibers. It is the most effective way to save polyester dyeing. [0003] With the improvement of people's living standards, people pay more and mo...
