Abstract

The invention discloses an antibacterial finishing technique of knitted fabric, which comprises the following steps: 1) mixing 1-2 parts by mass of titanium dioxide with the particle size of 45nm, 3-4 parts by mass of silver with the particle size of 10nm, 6-7 parts by mass of carboxymethyl cellulose and 4-5 parts by mass of hydroxypropyl methylcellulose while slowly adding 5-6 parts by mass of sodium silicate, 4-5 parts by mass of polyethyleneglycol bis stearate and 5-6 parts by mass of fatty alcohol polyethenoxy ether within 15 minutes, and continuing mixing for 25 minutes to obtain a nano antibacterial finishing solution; 2) immersing the washed and dehydrated knitted fabric in a dye vat filled with the nano antibacterial finishing solution in a bath ratio of 3:17, heating to 65 DEG C at the rate of 2 DEG C / minute, keeping the temperature for 50 minutes and dehydrating; 3) heating to 95 DEG C, and prebaking for 15 minutes; and 4) heating to 125 DEG C, and baking for 10 minutes. The technique can inhibit the knitted fabric from color change and enhance washing fastness, has enduring antimicrobial effect, and ensures favorable wearability of the knitted fabric.

Description

technical field [0001] The invention relates to an antibacterial finishing process for knitted fabrics. Background technique [0002] The existing antibacterial finishing process for knitted fabrics cannot inhibit the color change of knitted fabrics, the washability is not strong, and the antibacterial effect is not durable. Contents of the invention [0003] The object of the present invention is to provide an antibacterial finishing process for knitted fabrics, which can inhibit the color change of knitted fabrics, improve washability, have a long-lasting antibacterial effect, and ensure good wearability of knitted fabrics. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of antibacterial finishing process for knitted fabrics, comprising the steps of: [0005] 1) 1-2 parts by mass of titanium dioxide with a particle size of 45nm, 3-4 parts by mass of silver with a particle size of 10nm, 6-7 parts by mass ...
