Functional fiber method
The functional fiber method is to add a mothproof finishing agent to a fiber-forming polymer, spun it into a fiber with a mothproof effect, or chemically modify an existing fiber to make it have a mothproof fiber, and then use it. Anti-mite fibers are blended with other fibers to form tamper-proof woven fabrics or non-woven fabrics. There are two main ways to use this method:
1. Grafting of copper ions on acrylic fiber by chemical reaction, and connecting with modified acrylic fiber of X-GC golden C19H24N3+O group; or grafting on acrylic fiber by chemical reaction in the same way Copper ions, and connected to the X-GB blue C20H24N3 + O group made of modified fiber and other fibers mixed together, after opening, plaiting and other processes processing, made of anti-mite effect of acrylic non-woven fabrics.
2. A masterbatch obtained by mixing an ethylene-acetic acid copolymer containing 0.1% to 0.3% of an antimony finishing agent, benzalkonium, with a polypropylene polymer in a ratio of 84 to 16. This masterbatch is then mixed with a polypropylene polymer to obtain a polymer constituting a skin component. In addition, polyethylene terephthalate was used as the core of the fiber, and after being melt-composite spun together with the polymer constituting the skin component, it was heat-treated at 125° C. for 20 minutes to obtain a composite fiber having a mothproof effect.
In addition, acrylic fiber is also used as a substrate in foreign countries. When it is in a gel state, it is coated with various anti-caries finishing agents to make the anti-caries finishing agent penetrate the surface of the fiber and improve the anti-mite effect of fibers. The specific anti-caries agent, after special treatment, is added to the acrylic spinning solution to be blended, and then spinning, drying and shaping are performed to obtain an acrylic fiber with good anti-caries effect; and an anti-caries agent to be developed by itself. Anti-mite and antibacterial viscose filaments are made with dual anti-mite and anti-bacterial effects. The filaments are very effective, with a repellency rate of 99.9% for the aphids and an antibacterial rate of 99.9%. The fibers also have good durability and resistance to post-processing.
According to the relevant information, whether it is foreign or domestic use of functional fibers to obtain anti-mite textile materials or products, it is still in the stage of research and testing, and industrial production has not yet been realized. It is still necessary to continue research and test and realize industrial production as soon as possible.
Anti-mite fabric finishing method
Anti-mite fabric finishing method is the use of conventional fabric dyeing and finishing technology, such as spraying, padding, coating and other methods, in the anti-mite finishing solution on the fabric treatment made with anti-mite effect of the fabric.
The finishing method is a pure cotton fabric made by desizing, scouring, bleaching and mercerizing. After 80% of the liquid carrying rate is padding in the prepared anti-aging finishing liquid, it is dried at 120° C. for 2 minutes. Then, after curing at 160°C for 3 minutes, a pure cotton fabric with good mothproof effect is obtained; or a polyester fabric with a liquid content of 80% is subjected to padding in a flood prevention finishing solution and then dried at 100°C. , Heat treatment at 180°C for 1~2min to improve the anti-mite effect of polyester fabric.
Anti-mite finishing of fabrics is the most effective method used at home and abroad. The key to finishing is the anti-caries finishing agent used. The currently used anti-caries finishing agents include borneol derivatives such as Markamid 1-20, isobornyl cyanothioacetate, IBTA, etc.; deoxyacetic acid, such as Anincen CBP; N,N-diethylmethane amide; Carboxylic acid esters, such as o-dicarboxylic acid, dimethyl ester, decyl formate, etc.; diphenyl ethers; phthalimides; pyrethroids, etc.
Since the anti-caries finish on ordinary fabrics is generally processed by caustic soda scouring, oxychlorine bleaching, strong alkali mercerizing, etc., this requires the use of anti-caries finishing agent with acid, alkali, oxidation resistance and resistance Reducing performance, otherwise it will directly affect the anti-mite effect of anti-mite fabrics.
Anti-mite fabrics are mainly used to make bedclothes and are in direct contact with human body. It is absolutely necessary to ensure the safety of the anti-caries agent used on the human body and it will not affect the human body's physiological function. At the same time, it must not be produced during processing. Toxic compounds pose a hazard to operators.
The locusts are found in every corner of people's living environment and are a strong source of allergies that can cause harm to people's lives and health. The relevant departments monitored the distribution of dust mites in residents' homes with most carpets, followed by quilts, mattresses, pillows, floors, and sofas. A mattress that has been used for many years has between 100,000 and 10 million locusts. In a pillow that is used for two years, 10% of the weight is dead feces of dust mites and dust mites. Dust mite is very harmful to human health. Can spread viruses and bacteria, causing bronchial asthma, rhinitis, dermatitis, folliculitis, sputum and other diseases.
With the continuous improvement of people’s living standards and paying more attention to the living environment where they live, the use of textiles with anti-mite and anti-bacterial functions can not only suppress and drive fleas, but also effectively prevent various diseases related to dust mites, and can also inhibit bacteria and bacteria. The breeding of bacteria achieves the goal of improving the living environment.
At present, there are two kinds of processing methods for anti-mite fabrics at home and abroad: functional fiber method and tanning agent method.
