Example Embodiment

[0032] Example 1: An environmentally friendly dry skeleton fabrication process, including the following steps:

[0033] (1) Select the fiber: Select the fiber of the curling rate of no more than 10% as the first fiber, select the fiber of the curling rate ≥ 10% as the second fiber; the line density of the first fiber is 0.5dtex, the length is 25 mm;

[0034] (2) Rough opening: Using a starting device, the first fiber is initially started as the base layer fiber material; the first fiber and the second fiber are 2: 1 into a mixed ratio, and thoroughly mixed, to obtain a surface layer Web material;

[0035] (3) Fively open: Control the fed fiber uniform, open soft, and open the base layer fiber material and surface fibrous web materials, respectively;

[0036] (4) Put the base layer fiber material through gas flow, resulting in gram weight of 100 g / m 2 The base layer fiber web having a thickness of 2 mm; then the surface-containing web material passes through the airflow, and the ...

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...
