Mite is a body of about half a millimeter of arthropod animal products, it is more species. Among them, dust mites usually grow in mattresses, plush toys, sofas, bedding and pillows and other household items. Existing research shows that 97% of adults will be infected by mites, and common diseases include rhinitis and dermatitis. At present, most anti-mite fibers on the market are obtained by adding synthetic additives to the spinning solution and then spinning. The disadvantages of this type of fiber are: on the one hand, these additives are directly added to the fiber, which is easy to contact with human skin and affect human health; on the other hand, synthetic anti-mite additives are more toxic and more harmful to the human body. There are also some anti-mite fibers through the method of finishing, anti-mite additives on a variety of fibers, so as to play the role of anti-mite. The disadvantage of this method is that the finishing method will not only affect the quality of the fiber itself, but also cause the fabric to feel bad. At the same time, the washing resistance of the finishing additive is poor, and the anti-mite duration is short, which cannot meet the needs of consumers. There is a kind of anti-mite viscose fiber on the market, which is made by crushing the commercially available anti-mite agent into nano-scale powder and adding it to the viscose spinning solution for wet spinning. The effective components of the commercially available anti-acaricide are not clear, and its biological toxicity and ecological safety cannot be judged, which is not conducive to promotion. In addition, the preparation process of powdered acaricide is difficult and the cost is high.

In order to solve the above problems in the existing technology, the present invention provides a multifunctional function with sterilization function.Fiberboard. It adopts the following technical solutions: the fiberboard includes one layer of fiberboard composed of low melting point polyester fiber and three-dimensional crimped round hollow fiber from top to bottom; Fiberboard layer composed of low melting point polyester fiber and spiral regenerated fiber; Fiberboard layer composed of low melting point polyester fiber; Fiberboard layer composed of negative ion fiber; Fiberboard layer composed of low melting point polyester fiber and plant fiber;Fiberboard; There is a fluff layer above the first layer of fiberboardaA pile layer B is arranged under the first layer of polyester fiberboard; A glue layer is arranged between the first layer of fiberboard, the second layer of fiberboard, the third layer of fiberboard, the first layer of fiberboard and the first layer of polyester fiberboard.

Compared with the existing technology, the new type.FiberboardThe advantages are: first, by optimizing the structure and preparation materials, the fiberboard layer is composed of low melting point polyester fiber and plant fiber, polyester fiberboardLayer I has strong air permeabilitySo as to improve the stability and tensile strength of the device. Two is composed of negative ion fiberFiberboardThe inner fiber wall of the inner layer is adsorbed with a negative ion layer to prevent the mattress from being contaminated and mites breeding. The third is to optimize the structure to ensure a certain sound insulation effect, with good elasticity and tension. Four is the device can beInSterilization at a high temperature of about 180 degrees Celsius, while using physical methods to eliminate the growth of bacteria and dust mites, is conduciveGood sleep and human health.
