The principle of anti-mite knitted fabric

Author: Synwin–Mattress Manufacturer

There are mainly three types of anti-mite methods for textiles: one is to kill mites. This method is an important anti-mite measure, that is, the application of physical methods or chemical methods to kill mites. Physical methods such as sun exposure, heating, electromagnetic waves, and infrared rays can dry the fabric and destroy the living conditions of the mites. Chemical acaricidal methods are also important, such as the use of pyrethrum extract, dehydroacids, aromatic carbonates, diphenyl ethers, etc.

The second is to avoid mites, that is, to use repellents to drive away mites, which are substances with a smell or taste that mites are afraid of. Repel mites with touch, smell, taste to repel the points. The mechanism of action of currently used organic repellents, such as pyrethrins, acts on the nervous system of mites through contact, while toluamides act on the olfactory organs of mites through gasification.

The sense of smell is the application of volatile substances, such as pheromone; the sense of taste, such as organic acids, etc. But most of the repelling mites is to use the complex effect of smell and taste. In addition, for inorganic repellent, it does not rely on its evaporation to play the role of anti-mite, but the effect of contact repellent.

Various repellents have different effects on repelling mites. The third is to block mites. The blocking method is to use dense fabrics to prevent the mites from passing through, and in some cases repellents are used to further enhance the blocking effect.

In addition, since the remains of insects killed by pesticides are also allergic reaction allergens, the repelling mechanism has great advantages. In order to make consumers feel safe, some companies have developed agents that emphasize repellent properties in the anti-mite processing. There are several kinds of drugs that have been developed, some are used alone or two or more are used together to produce a synergistic effect.

Among the confirmed effective anti-mite processing agents, there are mainly amide-based compounds, thiocyanate-based compounds, aromatic compounds (carboxylate), and borneol derivative series. These anti-mite agents should meet the following basic conditions: 1. Highly active against dust mites: 2. Good anti-mite effect and can withstand processing conditions (heating, etc.); 4. Good compatibility with other additives; 5. No discoloration after processing; 6. Good durability, that is, good resistance to washing and weathering; 7. Suitable for both natural fibers and Taiwanese fibers; 8. Safety The safety of the anti-mite finishing agent is confirmed by multiple inspections including oral acute toxicity, mutagenicity test and skin irritation test. It is required that the anti-mite finishing agent must not affect the physiological function of the human body, and has good safety, especially for people with variable constitution and the skin irritation of infants and young children is negative.

At the same time, it is also required that the fibers or fabrics treated with anti-mite should not produce toxic compounds during subsequent weaving, dyeing and finishing, and use. Synwin Mattress, Foshan Mattress Factory, Foshan Brown Mat Factory: www.springmattressfactory.com.
