Problems solved by technology

[0006] (3) The third category is dry-laid skeleton cloth, which is the least used in the market and is not yet mature; the advantage is that it has no peculiar smell and no harmful VOC gas release; the disadvantage is that it has an ugly appearance, poor uniformity, fibers and threads, and hardness. Generally, it is necessary to increase the gram weight to increase the hardness

Embodiment 1

[0032] Embodiment 1: a kind of manufacturing process of environment-friendly dry-laid skeleton cloth, comprises the following steps:

[0033] (1) Select fibers: select fibers with a crimp rate no more than 10% as the first fiber, and select fibers with a crimp rate ≥ 10% as the second fiber; the linear density of the first fiber is 0.5dtex, and the length is 25mm;

[0034] (2) Coarse opening: using opening equipment, the first fiber is initially opened as the base layer fiber material; the first fiber and the second fiber are opened and fully mixed at a mixing ratio of 2:1 to obtain the surface layer web material;

[0035] (3) Fine opening: control the fed fibers to be uniform and soft, and finely open the base layer fiber material and the surface layer fiber web material respectively;

[0036] (4) The fiber material of the base layer is air-laid to obtain a grammage of 100g / m 2 , a base layer fiber web with a thickness of 2mm; then the surface layer fiber web material is ai...

Abstract

The invention discloses environment-friendly dry-method framework cloth and a preparation process thereof. The dry-method framework cloth comprises a base layer and a surface-layer fiber web compounded on the surface of the base layer; the base layer and the surface-layer fiber web are connected together through air laying and needling reinforcement; the base layer is prepared from first fibers with the crimp rate not exceeding 10% and the length larger than 20 mm; the surface-layer fiber web is prepared by mixing the first fibers with the crimp rate not exceeding 10% and the length larger than 20 mm and second fibers with the crimp rate larger than or equal to 10%; and the mixing ratio of the first fibers to the second fibers is (2-5): 1. The dry-method framework cloth has good hardness and strength, and is free of peculiar smell and VOC release.

Description

technical field [0001] The invention belongs to the technical field of air purification filter materials, and in particular relates to an environment-friendly dry-process skeleton cloth and a manufacturing process thereof. Background technique [0002] Skeleton cloth is suitable for household appliance filter materials (air purifiers, vacuum cleaners, etc.), automotive air conditioner filter materials, etc., and polyester ultra-short fibers are generally used. Skeleton cloth is manufactured by wet process, impregnation process or dry process. It has the characteristics of high stiffness, high air permeability and light weight. It is the first choice for filter materials. It will not be deformed in the case of large air volume passing through. [0003] The existing skeleton cloth manufacturing process mainly has the following advantages and disadvantages: [0004] (1) The first type of wet-process felt skeleton cloth, with the largest amount; the advantages are good-looking...
