Problems solved by technology

Direct use of antibacterial fiber has a long-lasting antibacterial effect, but it is only suitable for synthetic fibers and recycled fibers, which requires high technical requirements, complicated operation, and high cost; the use of antibacterial finishing agents is simple and convenient, suitable for most fiber textiles, and low cost
However, the durability of the antibacterial properties of the existing knitted fabrics obtained by using antibacterial finishing agents cannot be guaranteed, and it will have a certain impact on the wearability of the fabrics.

Embodiment 1

[0019] An antibacterial finishing process for knitted fabrics, comprising the following steps: first immerse the washed and dehydrated knitted fabrics in a dye vat filled with nano-antibacterial finishing solution, heat at a constant speed to 40°C, and keep warm for 30 minutes, then heat up to 80°C, pre-bake for 5 minutes, then raise the temperature to 110°C, and bake for 2 minutes.

[0020] Wherein, the nano antibacterial finishing solution comprises the following components by mass percentage: composite finishing agent 0.5%, adhesive 4% adopts ultra-soft and environmentally friendly adhesive TEP, and dispersant 3% adopts phosphorus-free high-efficiency chelating dispersant LA -48, the penetrant 2.5% uses non-ionic fast penetrant LK-31, and the liquor ratio is 1:10.

[0021] The composite finishing agent includes titanium dioxide and silver, wherein the particle size of the titanium dioxide is 65 nm, the particle size of the silver is 20 nm, and the mass percentage of titaniu...

Embodiment 2

[0023] An antibacterial finishing process for knitted fabrics, comprising the following steps: first immerse the washed and dehydrated knitted fabrics in a dye vat equipped with nano-antibacterial finishing liquid, heat at a constant speed to 45°C, and keep warm for 35 minutes, then heat up to 85°C, pre-bake for 3 minutes, then raise the temperature to 110°C, and bake for 1.5 minutes.

[0024] Wherein, the nano antibacterial finishing solution comprises the following components by mass percentage: composite finishing agent 1%, adhesive 4% adopts ultra-soft and environmentally friendly adhesive TEP, and dispersant 5% adopts phosphorus-free high-efficiency chelating dispersant LA -48, 3% of the penetrating agent is non-ionic fast penetrating agent LK-31, and the bath ratio is 1:10.

[0025] The composite finishing agent includes titanium dioxide and silver, wherein the particle size of the titanium dioxide is 60 nm, the particle size of the silver is 20 nm, and the mass percenta...

Abstract

The invention discloses an antibiotic finishing process for a knitted fabric, which comprises the following steps: firstly, soaking the knitted fabric which is washed and dehydrated into a dye vat with nano antibiotic finishing liquor, heating to the temperature of 35 to 45 DEG C at a uniform speed and carrying out heat preservation for 25 to 35 minutes; and then, after dehydrating, heating to the temperature of 75 to 85 DEG C, prebaking for 1 to 5 minutes, then heating to a temperature of 105 to 115 DEG C and baking for 1.5 to 2.5 minutes. The process disclosed by the invention inhibits color change of the knitted fabric, improves washability, has a more durable antibiotic effect and ensures excellent wearability of the knitted fabric.

Description

technical field [0001] The invention relates to the technical field of knitted fabric treatment, in particular to an antibacterial finishing process for knitted fabrics. Background technique [0002] Bacteria can proliferate rapidly in a humid environment, and the climatic conditions formed between the human body and ordinary knitted fabrics are the best place for the reproduction and reproduction of microorganisms. Therefore, various knitted fabrics used by people every day have become the main source of bacterial reproduction and spread. one of the carriers. [0003] With the improvement of living standards, people's awareness of health care for knitted fabrics is increasing, and close-fitting knitted fabrics with health, antibacterial, environmental protection and safety properties are favored by consumers. The processing of existing antibacterial knitted fabrics mainly adopts two technical approaches: one is to add antibacterial agents before fiber spinning, and perform...
