Aphids are a kind of organisms that are very harmful to human health and can spread viruses and bacteria, and can cause various diseases such as hemorrhagic fever, dermatitis, folliculitis, and phlegm. According to statistics, 60% of asthma patients have an allergic reaction to dust mite antigens, and 80% of children's asthma is caused by dust mite antigen allergy. A large number of clinical studies abroad have also found that early childhood exposure to dust mite allergens in the family is closely related to children who later developed asthma.
The emergence of flood-preventing textiles enables human beings to stay away from the harm of locusts and to defend our health. Anti-mite textiles are also increasingly entering people's lives. It is understood that there are two ways to prevent decay in textiles, one is physical flood control, and the other is chemical flood control. Chemical anti-mite is the use of anti-mite and anti-bacterial finishing agents to treat fabrics, so that the fabric has anti-mite function. So, what about the safety of anti-caries agents? How do the anti-caries agents are used in textiles? Does the country have standards in this area? A reporter from China Textile Economic Information Network (hereafter referred to as CTEI) interviewed Wang Xingfu, director of the technical center of Beijing Jieer Shuang High-tech Company and senior engineer Wang Xingfu, asking him to read out the relevant issues of anti-caries agent for readers.
CTEI: The components of the anti-caries agent are harmless to the human body. Can the anti-mite performance of the finished fabric be reduced after washing?
Wang Xingfu: In recent years, the diseases caused by locusts have been widely reported in various media, making the damage of locusts increasingly becoming the focus of attention. In winter, the climate is very dry, especially in the north, and the water is very scarce. People's skin will be in a state of water shortage for a long time, so it may produce a large amount of sebum and dander secretions. And these secretions can provide very rich food sources for locusts.
Anti-bacterial anti-bacterial finishing is to use anti-mite anti-bacterial agent treatment fabrics, so as to obtain anti-mite, anti-bacterial, anti-mildew, deodorant, keep the textiles clean and sanitary processing technology. Its purpose is not only to keep the fabrics clean, but also to prevent infectious diseases, ensure the safety and health of the human body and wear comfort, reduce the cross-infection rate of the public environment, and enable the fabric to obtain new functions of health care.
The safety of antibacterial antibacterial agents to humans can be verified from the results of toxicity experiments.
(1) Acute oral toxicity of antibacterial and antibacterial finishing agents; According to the classification criteria of acute toxicity, the application liquid of anti-caries antibacterial finishing agent is actually non-toxic substance.
(2) Skin irritation: According to the skin irritation intensity classification standard, the antibacterial agent application liquid is non-irritating to the skin.
(3) Eye irritancy: According to eye stimulating intensity grading standard, the anti-caries antibacterial agent application liquid is non-irritating to eyes.
(4) Micronucleus test: In accordance with GB7919-87 experimental method, the micronucleus test of bone marrow polychromatic erythroblasts in mice was performed. The results showed that there was no significant difference in the incidence of micronucleus in the anti-bacterial and antibacterial finishing sample group and the solvent control group. No in vivo mutagenicity was observed.
Anti-mite fabrics are made of anti-mite finishes with active chemical reactions. They form an insect-repellent film on the surface of fabrics, have efficient and rapid knock-out killing effect on mites, and have a good repellent effect. At the same time, the anti-mite fabric has good washing resistance, can withstand more than 30 times of household washing conditions, without losing the anti-mite effect.
CTEI: Are there any national standards for anti-cockroach agents? These standards mainly specify which indicators.
Wang Xingfu: In recent years, with the continuous expansion of the application of flood prevention textiles on the market, it is necessary to comprehensively assess and standardize qualitative and quantitative evaluation methods for flood prevention textiles. Not only do production companies hope to adopt scientific test methods to test and understand products, improve production processes, and achieve reasonable levels of flood protection, but consumers also want to have a unified index to characterize flood protection to illustrate and promote products. Anti-mite effect achieved.
In order to improve the quality of flood prevention textiles, eliminate counterfeit and shoddy products from flooding the market, and protect the interests of producers and consumers, it is necessary to establish a rapid measurement method and uniform standards to regulate and promote the development of flood prevention textiles. The textile industry standard FZ/T01100-2008 "Evaluation of Textile Flood Control Performance" drafted and drafted by Beijing Jieer Shuang High-tech Co., Ltd. on March 12, 2008 was implemented on September 1, 2008, and the standard was revised and upgraded in the same year. The national standard GB/T 24253-2009 "Assessment of the Properties of Textile Flood Control" was implemented on February 1, 2010.
Taking into account the internationally widely used main methods for the determination of the effects of flood prevention, the "Intrusion Prevention Method", the "Glass Tube Method", and the "Simplification and Utility" of the "Proliferation Inhibition Method" to prevent the growth of aphids, these methods are used to establish standards. The basis.
Flood control performance test: Flood control performance is measured by the repellency rate of aphids. The repellency rate is calculated as follows.
Repellent rate = (1-) × 100%
CTEI: What are the characteristics of Jier Shuang's anti-caries agent?
Wang Xingfu: Beijing Jieer Shuang High-tech Co., Ltd. has been engaged in antibacterial finishing research has 19 years of experience, our company mass production of antibacterial finishing agents and antibacterial finishing cloth, the Chinese People's Liberation Army 90 training shoes using the company's production of antibacterial deodorant in the bottom cloth . The anti-bacterial antiseptic finishing agent SC-998 produced by our company has high efficiency, broad-spectrum anti-bacterial property, excellent durability, and good safety.
Antibacterial and anti-caries finishing agent SCJ-998 is suitable for anti-mite and antibacterial finishing of cotton, wool, silk, wool and blended fabrics with chemical fiber. Its main component is a chlorobenzimidazole polymer compound with a pyrazole amide structure with active groups and microcapsules based on pyrethroid compounds. The active groups attached to SCJ-998 can be used on fibers. OH, -NH- form a covalent bond, so that the fabric after antibacterial and anti-mite treatment has excellent washing resistance; SCJ-998 with antibacterial groups act on the bacterial cell membrane, cell membrane defects, increased permeability, cells The leakage of cytoplasm inside can also hinder the synthesis of bacterial proteins and cause the depletion of the body's core protein body, which in turn kills the bacteria; the antibacterial group of SCJ-998 also acts selectively on the ergot of the fungal cell membrane. Sterols change the permeability of cell membranes, leading to the loss of important substances in the cells and death of fungi. At the same time, SCJ-998 forms an insecticide-resistant film on the fabric surface, which can effectively and quickly kill locusts and have a good repellent effect.
Antibacterial and anti-caries finishing agent SCJ-998 is composed of three components: SCJ-998A, SCJ-998B and 998C. Antibacterial anti-caries finishing agent SCJ-998 is non-flammable, non-explosive and non-toxic to human body. The antibacterial agent SCJ-998 has no adverse effect on the whiteness, shade, strength, feel and breathability of fabrics (the intellectual property of this product is protected by national laws).
CTEI: Will fabrics with anticaries agents affect the anti-cariogenic effects after dyeing and are there limitations on dyeing?
Wang Xingfu: The method for treating fabrics with anti-bacterial and antibacterial finishing agent SCJ-998 can be padding and dipping coating. The amount of SCJ-998 is 3 to 6% o. w. f (ie 3 Kg to 6 Kg SCJ-998 per 100 Kg dry fabric), depending on the type and use of the fabric being treated.
Padding process: fabric-->dyeing-->drying-->dip anti-mite antibacterial solution (rolling rate 75%)-->drying (80-100°C)-->high temperature tenter (150°C × 20-30 seconds, or 120°C × 3-4 minutes).
From the above process point of view, because the anti-mite finishing is after the dyeing process, the anti-mite finishing does not affect the dyeing effect.
CTEI: Mainly used in those areas?
Wang Xingfu: The anti-bacterial antibacterial agent SCJ-998 has good safety, broad-spectrum high-efficiency anti-cariogenic anti-bacterial properties and excellent washing resistance. The anti-bacterial and anti-bacterial finishing agent SCJ-998 is low in price and easy to use. It is suitable for anti-mite and anti-bacterial finishing of cotton, linen, silk, wool, polyester/cotton, polyamide, acrylic, viscose and other fabrics. It is used to produce bedding textiles, underwear, towels, carpets, interior decoration products, air filter materials, and textiles that have anti-mite, antibacterial, odor-repellent and mildew-proof functions.
With the strengthening of product quality supervision and standardization work, as well as the rapid development of China’s economy and the rapid improvement of people’s living standards, people’s demand for various types of functional products will continue to increase. Especially in the past two years, domestic and even global, biosafety incidents have occurred frequently. More and more consumers are aware of the seriousness of biohazards, and at the same time, they have also promoted the research and development of various functional and health-care products, such as antimicrobials. Fabrics, anti-drip bedding and mattresses, anti-smashing carpets, anti-dark curtains, etc.
