preparation example Construction

[0026] A kind of preparation method of the high-elastic nonwoven fabric of above-mentioned honeycomb structure, this method comprises the steps:

[0027] (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 6, the we...

Embodiment

[0059] A high-elastic nonwoven fabric with a honeycomb structure with a thickness of 105 mm and a preparation method thereof.

[0060] See figure 1 , figure 2 , a high-elastic nonwoven fabric with a thickness of 105mm honeycomb structure, including a plurality of composite fiber webs 1 stacked in sequence, characterized in that: the composite fiber webs 1 are connected end to end in sequence, arranged in a zigzag back and forth, adjacent There is a fiber layer angle 3 between the composite fiber webs 1, and the fiber layer angle 3 is less than 1 degree and approaches 1 degree, and there are hot-melt fibers 2 between adjacent composite fiber webs 1, and the hot-melt fiber Fiber 2 is a low-melting-point polyester staple fiber with a melting point of 110°, a fineness of 2D, and a length of 51 mm.

Abstract

A high-elastic non-woven fabric with a honeycomb structure comprises a plurality of compound fiber meshes sequentially stacked in a back-and-forth Z shape. The compound fiber meshes are sequentially in end-to-end connection, and a hot melting fiber is clamped between the adjacent compound fiber meshes. When the high-elastic non-woven fabric is manufactured, through preparation prior to mesh formation and a process of mesh formation through mechanical combing, an upper layer fiber mesh, an elastic fiber mesh and a lower layer fiber mesh are prepared respectively and then are overlaid into the compound fiber mesh through a fiber mesh compounding process; each of the upper layer fiber mesh and the lower layer fiber mesh is the mixture of a low melting point polyester short fiber and a three-dimensional curly hollow polyester short fiber, and the elastic fiber mesh is the mixture of a low melting point polyester short fiber and an elastic polyester short fiber. The prepared compound fiber meshes are vertically laid through a vertical mesh laying process, the hot melting fiber is scattered between the compound fiber meshes, and then the high-elastic non-woven fabric with the honeycomb structure is obtained through a drying, trimming and winding process. The high-elastic non-woven fabric not only is high in elasticity and simple in structure, but also is low in cost and environmentally friendly.

Description

technical field [0001] The invention relates to a high-elastic 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 waste, and it is e...
