Embodiment 1

[0028] The antibacterial fiber contains 20% chitosan, 3% sodium polyacrylate PAAS, 5% acetic acid, 2%-maleic anhydride and PET in the weight percentage.

[0029] The method for antibacterial fiber, comprises the following steps:

[0030] (1) preparation contains chitosan eutectic composition

[0031] In terms of weight percentage, mix 20% chitosan, 3% sodium polyacrylate PAAS, 5% acetic acid, 2% maleic anhydride and part of PET, and knead at 170-200°C to obtain a chitosan co-melt combination. The material is then cooled and discharged, and crushed by a plastic crusher to a chitosan-containing eutectic composition powder below 5 mm for subsequent use; wherein the weight ratio of chitosan to PET is 1: 2.5;

[0032] (2) Prepare chitosan-containing antibacterial masterbatch, mix the chitosan-containing eutectic composition powder prepared in step 1 with PET in a weight ratio of 1-3, melt and co-extrude through a co-rotating twin-screw extruder, water-cool, and cut Granules, drie...

Embodiment 2

[0036] The antibacterial fiber contains 25% chitosan, 4% sodium polyacrylate PAAS, 7% acetic acid, 3%-maleic anhydride and PET in the weight percentage.

[0037] The method for antibacterial fiber, comprises the following steps:

[0038] (1) preparation contains chitosan eutectic composition

[0039] In terms of weight percentage, mix 25% chitosan, 4% sodium polyacrylate PAAS, 7% acetic acid, 3%-maleic anhydride and part of PET, and knead at 170-200°C to obtain chitosan co-melting The composition is then cooled and discharged, and pulverized by a plastic crusher to a chitosan-containing eutectic composition powder below 5 mm for subsequent use; wherein the weight ratio of chitosan to PET is 1: 2.5;

[0040] (2) Preparation of chitosan-containing antibacterial masterbatch

[0041] Mix the chitosan-containing co-melt composition powder prepared in step 1 with PET in a weight ratio of 1-3, melt and co-extrude through a co-rotating twin-screw extruder, water-cool, pelletize, and...

Embodiment 3

[0045] The antibacterial fiber contains 30% chitosan, 5% sodium polyacrylate PAAS, 10% acetic acid, 5%-maleic anhydride and PET in the weight percentage.

[0046] The method for antibacterial fiber, comprises the following steps:

[0047] (1) preparation contains chitosan eutectic composition

[0048] In terms of weight percentage, mix 30% chitosan, 5% sodium polyacrylate PAAS, 10% acetic acid, 5%-maleic anhydride and part of PET, and knead at 170-200°C to obtain chitosan co-melting The composition is then cooled, discharged, and pulverized by a plastic crusher to a chitosan-containing eutectic composition powder below 5 mm for subsequent use; wherein the weight ratio of chitosan to PET is 1: 2.5;

[0049] (2) Preparation of chitosan-containing antibacterial masterbatch

[0050] Mix the chitosan-containing co-melt composition powder prepared in step 1 with PET in a weight ratio of 1-3, melt and co-extrude through a co-rotating twin-screw extruder, water-cool, pelletize, and ...

Abstract

The invention provides an antibiotic fiber. The antibiotic fiber comprises, by weight, 20-30% of chitosan, 3-5% of a dispersant, 5-10% of a fusogen, 2-5% of a grafting modifier, and the balance PET. The invention also provides a preparation method of the antibiotic fiber, and a pillow core and a quilt core containing the antibiotic fiber as a filling material. Present antibiotic products have safety performance problems and defects which are not adapted to industrial production, so the antibiotic fiber of the invention which can highly effectively inhibit more than twenty harmful bacteria of escherichia coli, staphylococcus aureus, Candida albicans and the like with an average bacteriostasis rate of equal to or more than 98%, and can not generate side effects to beneficial flora in human bodies has the effect of ecological bacteriostasis, and is adapted to industrial production.

Description

technical field [0001] The invention relates to an antibacterial fiber, a preparation method thereof, a pillow core and a quilt core containing the antibacterial fiber. Background technique [0002] At present, most of the fiber raw materials used in the textile products of underwear, hosiery and bedding in the world are cotton fibers or blended with other chemical fibers. These fibers do not have a good function of inhibiting and killing bacteria. After entering the 21st century, people put forward higher requirements for home textile products such as underwear, hosiery, bedding, etc.: moisture guide, water absorption, perspiration, antibacterial, personal comfort and hygiene, while the existing These cotton fibers or blended products with other chemical fibers cannot meet these needs. [0003] The macromolecular structure of PET fiber itself has strong antimicrobial properties, but because it will be "contaminated" with various oils, auxiliaries and finishing agents durin...
