preparation example Construction

[0022] A method for preparing the high-elastic upright cotton of the above-mentioned film bonded honeycomb structure, the method comprises the steps of:

[0023] (1) Preparation before web formation: first 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 absorb moisture compared with natural fibers. Poor performance, 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. In fiber web 1, 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%; the low-melting point polye...

Embodiment 1

[0031] The invention relates to a high-elastic standing cotton with a film-bonded honeycomb structure and a preparation method thereof with a three-dimensional crimped hollow polyester staple fiber as a base material.

[0032] See figure 1 , the high-elastic upright cotton of the film-bonded honeycomb structure, including a plurality of fiber webs 1 stacked in sequence, is characterized in that: the fiber webs 1 are connected end to end in sequence, and the arrangement mode is a back and forth Z-shaped, adjacent The angle between the fiber webs 1 is 0 degree or close to 0 degree, and a hot-melt film 2 is sandwiched between adjacent fiber webs 1 . The structure of the hot-melt film 2 is net shape, the melting point is less than or equal to 110°, and the thickness is less than 0.05mm.

Abstract

Film bonded type honeycomb structured high-elastic upright cotton comprises a plurality of fiber webs formed in a sequentially repeated Z-shaped laminated mode, the fiber webs are sequentially connected end to end, and hot melting films are sandwiched between adjacent fiber webs. The fiber webs are prepared through processes of web forming preparation and mechanical carding web forming. The fiber webs are a mixture of low-melting polyester staple fiber and elastic polyester staple fiber, the low-melting polyester staple fiber is 15% to 35% by weight, and the elastic polyester staple fiber is 65% to 85% by weight. The prepared fiber webs is subjected to processes of fiber web film laying by laying the hot melting films on both sides of every fiber web, vertical layering, drying, trimming and winding to obtain the film bonded type honeycomb structured high-elastic upright cotton. The film bonded type honeycomb structured high-elastic upright cotton is high in elasticity, simple in structure, low in cost and environmentally friendly.

Description

technical field [0001] The invention relates to a high-elastic upright cotton with a film-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-recyclable waste, ...
