Problems solved by technology

In the above process, the group B treatment agent is sprayed on the fabric by atomization. In the actual process application, special atomization equipment, microwave processor and centrifuge must be added to complete the process. The investment is large, the process cost is increased, and the atomization It is difficult to evenly distribute the spray paint on the fabric during processing, which affects the processing quality and feels bad
At the same time, this kind of spraying only makes the spray paint adhere to the surface of the fabric. In fact, it is difficult to make the spray paint effectively penetrate into the gaps and fiber pores of the fabric. poor washing

Embodiment 1

[0049] One, prepare finishing solution A, its weight ratio is:

[0050] AgNO 3 : 0.15%, Water: 99.5%,

[0051] Polyvinylpyrrolidone: 0.18%, fatty alcohol polyoxyethylene ether: 0.17%;

[0052] 2. Immerse the fabric in the finishing solution A by padding, and control the excess rate to 60%;

[0053] Three, prepare finishing solution B, its weight ratio is:

[0054] Water: 99.8%, Sodium tetrahydroborate: 0.1%,

[0055] Fatty alcohol polyoxyethylene ether: 0.1%;

[0056] 4. The fabric soaked in finishing solution A is soaked in finishing solution B by padding, so that finishing solution A and finishing solution B undergo a chemical reaction to generate nano-metallic silver particles with antibacterial and deodorizing effects; The surface action energy of the particles is very strong, which makes it easy for the nano-silver particles to agglomerate. At this time, the protective agent polyvinylpyrrolidone, which has both protection and dispersion effects, effectively prevents ...

Embodiment 2

[0060] The process and steps of embodiment two are the same as those of embodiment one, but its finishing solution A is slightly different from the components of finishing solution B:

[0061] Finishing liquid A, its weight ratio is:

[0062] AgNO 3 : 0.1%, Water: 99.7%,

[0063] Polyvinylpyrrolidone: 0.08%, fatty alcohol polyoxyethylene ether: 0.12%;

[0064] Finishing liquid B, its formula weight ratio is:

[0065] Water: 99.9%, Sodium tetrahydroborate: 0.04%,

[0066] Fatty alcohol polyoxyethylene ether: 0.06%;

[0067] Wherein, by padding car, when the fabric is dipped in finishing liquid A, control the excess rate of 55%; by padding, when the fabric soaked in finishing liquid A is immersed in finishing liquid B, control the excess rate of 60%. %; The process of drying and setting the washed fabric should be carried out at 95°C.

Abstract

This invention relates to a method for preparing an antibiotic stinking-proof textile, which comprises the following steps: 1) preparing A finishing liquid including AgNO3, penetrant and dispersing preservative; 2) immersing the textile in the A liquid by pad mangle; 3) preparing B finishing liquid including reducer and dye leveler; 4) immersing the textile in the B liquid by the pad mangle and reacting to generate the nanometer silver particles; 5) cleaning the finishing liquid not reacted; 6) drying and shaping. The penetration, dispersing protection, reduction and equalizing technology are all proceeding in the liquid, by which the compounded nanometer silver particles can be absorbed and penetrated in the surface and gap of the textile evenly.

Description

Technical field: [0001] The invention relates to the field of functional fabrics, in particular to a preparation method of high-efficiency antibacterial and deodorant fabrics. Background technique: [0002] In nature, microorganisms exist widely. Because textiles are also an important medium for transmitting germs, people will inevitably come into contact with various microorganisms in daily life. Under normal circumstances, we do not feel the harm of pathogenic bacteria, but when the conditions are suitable, the pathogenic bacteria on the human skin gather and multiply in large numbers, and cause great harm to human health through the skin, respiratory tract, digestive tract and blood. This is also one of the main causes of disease. [0003] On the one hand, antibacterial and deodorant textiles can protect the fabric itself, including preventing the surface of textile fibers from staining, discoloration, embrittlement, and anti-microbial protection of fiber products in st...
