Problems solved by technology

Inorganic antibacterial agents have the advantages of safety, heat resistance, durability, and durability. The disadvantages are that they are expensive, and some antibacterial agents have heavy metal toxicity problems. The quality of inorganic antibacterial agents on the market is also uneven.
However, limited by the quantity of raw materials and processing conditions, natural antibacterial agents cannot be marketed on a large scale, and they begin to decompose when the temperature reaches 160-180°C, which greatly limits their application range.

Abstract

The invention discloses an antibacterial agent for compound fabric and an application of the antibacterial agent and belongs to the technical field of functional design of textile. The antibacterial agent comprises components in parts by weight as follows: 0.7-1.5 parts of tetrakis hydroxymethyl phosphonium sulfate, 2-4 parts of sodium hypophosphite, 1-2 parts of sodium hexametaphosphate, 0.1-0.2 parts of sodium carboxymethylcellulose, 0.1 parts of choline chloride and 80-100 parts of water. The antibacterial agent is applied to the antibiotic finish process of pure cotton fabric and comprises finish steps as follows: step one, the pure cotton fabric is soaked in a sodium citrate solution, taken out and drained; step two, the drained pure cotton fabric is subjected to double dipping and double rolling in the antibacterial agent, the pick-up is 30%, and the pure cotton fabric is dried, baked, washed with soap and aired. The antibacterial agent doesn't contain heavy metal or organic halogen, doesn't have poor effect on the environment and has high safety; the heat resistance is higher, and the antibacterial effect lasts long; meanwhile, the preparation cost is low, a process is simple, and industrial popularization is facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of textile functional design, and relates to a composite fabric antibacterial agent and its application. Background technique: [0002] Antibacterial agents are an important component of textile antibacterial finishing, which can be divided into three categories according to their structure: inorganic, organic and natural antibacterial agents. Inorganic antibacterial agents have the advantages of safety, heat resistance, durability, and durability. The disadvantages are that they are expensive, and some antibacterial agents have heavy metal toxicity problems. The quality of inorganic antibacterial agents on the market is also uneven. Organic antibacterial agent is the earliest antibacterial agent used, and it is also the main body of antibacterial agent for fabrics. There are two types of elution type and non-elution type. Many; but some organic antibacterial agents are more toxic, will produce microbial r...
