preparation example Construction

[0023] A method for preparing the above-mentioned fiber-bonded honeycomb structure of high-elastic flame-retardant upright cotton, characterized in that: the method comprises the following steps:

[0024] (1) Preparation before web formation: Mix and open the various fiber raw materials required for the preparation of fiber web 1. The non-woven mixed opening equipment operates at a high speed. Since the raw materials are all chemical fibers, they are hygroscopic compared with natural fibers. Poor, it is easy to generate static electricity in the mixed opening process, adding oil agent during the opening process can prevent the product quality from being affected by static electricity. The preparation material of fiber web 1 is a mixture of low melting point polyester staple fiber and elastic polyester staple fiber, the weight percentage of low melting point polyester staple fiber is 15%~35%, and the weight percentage of elastic polyester staple fiber is 65%~85% . Low-melting ...

Abstract

The invention discloses high-elastic flame-resistant upright cotton of fiber bonding type honeycomb structure. The high-elastic flame-resistant upright cotton of the fiber bonding type honeycomb structure comprises round-trip Z-type successively laminated fiber webs; the mixed powders of hot melting powders and flame-resistant powders are sprayed in the fiber webs; the fiber webs are successively connected end to end; and hot melting fibers are clamped between the neighboring fiber webs. During the preparation, the fiber webs are prepared by the web forming pre-preparation and mechanical combing web forming processes; the web net is the mixture of low-melting-point polyester staple fibers and elastic polyester staple fibers; and the weight percentage of the low-melting-point polyester staple fibers is 15%-35%, and the weight percentage of the elastic polyester staple fibers is 65%-85%. After the mixed powders of the hot melting powders and the flame-resistant powders are sprayed to the fiber webs, the fiber webs performs the vertical web through the vertical web process, and the hot melting fibers are sprayed between the fiber webs, so the high-elastic flame-resistant upright cotton of the fiber bonding type honeycomb structure is prepared by drying, edge-cutting and winding processes. The high-elastic flame-resistant upright cotton of the fiber bonding type honeycomb structure has the characters of high elasticity, good fire resistance, simple structure, low cost, and environment friendliness.

Description

technical field [0001] The invention relates to a high-elastic flame-retardant upright cotton with a fiber-bonded honeycomb structure and a manufacturing method thereof, belonging to the field of nonwoven fabrics. Background technique [0002] Fluffy materials are a necessity of human social life and are closely related to people's lives. For example, sound insulation materials, sofas, mattresses, boss chairs, sports equipment, clothing and other fields need to use fluffy materials. According to the preparation method of fluffy materials, there are usually four categories: sponge, warp-knitted spacer fabric, three-dimensional elastic woven fabric, and non-woven fabric. Sponge is a kind of porous material, which is mainly made of soft foam in polyurethane foam. Because of its low price, light weight, soft and plump hand feeling and good resilience, sponge occupies a dominant position in the market. However, sponge production has fatal shortcomings such as pollution and non-r...
