preparation example Construction

[0028] A method for preparing a high-elastic flame-retardant nonwoven fabric of the above-mentioned honeycomb structure, the method comprises the steps of:

[0029](1) Preparation before web formation: first mix and open various fiber raw materials required for preparing the upper layer fiber web 4 , the elastic fiber web 5 and the lower layer fiber web 6 . The non-woven mixed opening equipment runs at a high speed. Since the raw materials are all chemical fibers, the hygroscopicity is poor compared with natural ones. Static electricity is easily generated during the mixed opening process. Adding an oil agent during the opening process can prevent static electricity from being generated. And affect product quality. The preparation material of the upper layer fiber web 4 and the lower layer fiber web 6 is a mixture of low-melting point polyester staple fiber and three-dimensional crimped hollow polyester staple fiber. In the upper layer fiber web 4 and the lower layer fiber web...

Abstract

The invention relates to a high-elastic flame-retardant non-woven cloth of a honeycomb structure. The high-elastic flame-retardant non-woven cloth of the honeycomb structure comprises a plurality of compound fiber webs which are stacked in a round-trip Z shape. The inner sides of the fiber webs are spread with mixed powders of hot-melting powders and flame-retardant powders. The compound fiber webs are connected from heads to ends in sequence. Hot-melting fibers are clamped between adjacent compound fiber webs. When the high-elastic flame-retardant non-woven cloth of honeycomb structure is manufactured, an upper layer fiber web, an elastic fiber web and a lower layer fiber web are prepared respectively through the processes of reparation before web forming and carding web by a machine. The hot-melting powders and flame-retardant powders are spread on the upper layer fiber web, the elastic fiber web and the lower layer fiber web. The upper layer fiber web, the elastic fiber web and the lower layer fiber web are overlapped into a compound fiber web. The upper layer fiber web and the lower layer fiber web are a mixture of low-melting-point dacron staple fibers and three-dimensional crimped hollow dacron staple fibers. The elastic fiber web is a mixture of low-melting-point dacron staple fibers and elastic polyester staple fiber. Vertical lapping is conducted through the process of vertical lapping, hot-melting fibers are spread between the compound fiber webs, and the high-elastic flame-retardant non-woven cloth of the honeycomb structure is manufactured through the processes of drying, trimming and winding.

Description

technical field [0001] The invention relates to a high-elastic flame-retardant nonwoven fabric with a 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-recyclable wa...
