Thermoplastic fiber bonded palm fiber mattress core material and preparation method thereof

Abstract

The invention discloses a palm fiber mattress core material bonded by thermoplastic fibers. The palm fiber mattress core material sequentially comprises a non-woven fabric surface layer, a PP melt-blown non-woven fabric layer, a palm fiber layer and a non-woven fabric bottom layer, wherein the palm fiber layer has a net layer structure formed by dispersing and mixing thermoplastic fibers and palmfibers and then thermally bonding, the thermoplastic fibers are selected from PP, PET, PA, PE and ES fibers, and the palm fibers are selected from palm fibers and / or coconut fibers. According to the invention, the adopted PP and other conventional materials are wide in source and low in price, are thermoplastic materials, and can be recycled through a certain technology, so that the used materialshas cost advantage and environmental protection performance in bonding and compounding of palm fibers.

Description

technical field [0001] The invention relates to the technical field of layered products, in particular to a thermoplastic fiber-bonded brown silk mattress core material and a preparation method of the brown silk mattress core material. Background technique [0002] Brown silk mattresses are currently one of the most popular types of mattresses. The natural characteristics of its main raw materials cater to the current consumer psychology of advocating nature. The palm silk used mainly includes mountain palm or palm fiber (mainly palm leaf sheath fiber) and coconut silk fiber (coconut husk fiber). Both fibers are natural fiber resources with a wide range of sources and low prices. It is of positive significance to fully develop and utilize the two fibers. Especially palm fiber, it has the characteristics of not easy to be moldy and moth-eaten, not easy to be chemically corroded, high rigidity, excellent elasticity and toughness, not easy to break, and porous structure.

Problems solved by technology

This patented method uses low-melting point two-component sheath-core fiber as the binder between fibers instead of glue, so as to achieve the technical effect of environmental protection and formaldehyde-free, but also, the middle layer is mixed, carded, paved The processing of low-melting point two-component sheath-core fiber and coir fiber by netting will cause uneven web formation due to the great difference in the properties of the two fibers, and the process of three-layer one-time integral molding is likely to cause a low melting point in the middle layer Insufficient heating of two-component sheath-core fiber and coir fiber will affect the bonding effect and ultimately affect the elasticity and durability
