example 1

[0030] Add 10 grams of silver-loaded nano-zinc oxide powder into the three-necked flask, add 0.3 grams of silane coupling agent (KH-560) into it, use absolute ethanol as solvent, and stir and reflux at 78° C. for 2.5 hours. The treated sample is dried and ground to obtain surface-modified silver-loaded nano zinc oxide particles.

example 2

[0032] Add 30 grams of silver-loaded nano-zinc oxide powder into the three-necked flask, add 1 gram of silane coupling agent (KH-560) into it, use absolute ethanol as solvent, and stir and reflux at 80° C. for 3 hours. The treated sample is dried and ground to obtain surface-modified silver-loaded nano zinc oxide particles.

example 3

[0034] The silver-loaded (Ag + The content is 3%) nano-zinc oxide powder, 20 grams of dispersant (polyethylene wax-1#) and 680 grams of pre-crystallized and dried pure PET chips are blended and extruded on a twin-screw extruder, and the temperature in each zone of the granulation process is The order is 165°C, 265°C, 265°C, 265°C, 260°C. Then it is pelletized by a plastic pelletizer. The antibacterial masterbatch with good dispersion effect and high antibacterial agent content is obtained.

Abstract

The invention provides an antibiotic PET fiber with silver nanometer zinc oxide, relative preparation method and application. The invention uses the method of composite spinning to add the silver nanometer zinc oxide into the layer of terylene, while prepared modified terylene has higher antibiotic sterilize ability. The invention can apply the mass continuous production of fusion spinning modified terylene.

Description

technical field [0001] The invention relates to an antibacterial PET fiber and a preparation method thereof, in particular to an antibacterial PET fiber modified by silver-loaded nano-zinc oxide and a preparation method thereof. Background technique [0002] In real life, people will inevitably come into contact with microorganisms such as various bacteria and fungi. These microorganisms grow and multiply rapidly under suitable environmental conditions, and spread diseases through contact, affecting people's health. In daily life, all kinds of textiles are a good living place for these microorganisms and an important source of disease transmission. Human beings live surrounded by microorganisms. Fiber can absorb many microorganisms. If the temperature is appropriate, these microorganisms will multiply rapidly and cause various harms to the human body. In recent years, the antibacterial properties of fiber products have attracted more and more attention. The research on fi...
