Embodiment

[0014] This embodiment is a cross-shaped non-woven polyester fiber multi-layer fast filter fabric, which provides a multi-layered structure for deep filtration. The structure of the cross-shaped cross-section fiber is used to generate grooves, so that the efficiency of liquid filtration can be improved and the lateral flow can be reduced. The consumption of textile fabrics has the advantages of surface filtration and depth filtration at the same time. Its preparation process comprises the following steps:

[0015] 1) Take 40 parts of acrylic resin, add 0.5 parts of ammonia water and 59.5 parts of water in sequence and mix evenly to obtain a resin solution;

[0016] 2) Use 2D*51mm cross-section polyester as the raw material, output the cotton net according to the general non-woven fabric process, and keep the fibers as smooth as possible, and control the cotton weight of the carding machine to 10g / m 2 ~11g / m 2 , and at the same time reduce the speed of the main cylinder wheel...

Abstract

The invention discloses cross-shape profiled-section polyester fiber multilayer quick-filtering nonwoven, prepared by: 1) adding 0.5 part of liquid ammonia and 59.5 parts of water into 40 parts of acrylic resin, and mixing well to obtain resin solution; 2) using cross-section polyester of 2D*51 mm as a raw material to discharge a cotton mesh; 3) using a cotton spreading machine to make the cottonmesh into a multilayer nonwoven cotton mesh having six layers of fiber; 4) introducing air bubbles into the resin solution; 5) mixing well the multilayer nonwoven cotton mesh and the bubbled resin solution; 6) drying. The problem is solved that profiled-section fiber has insufficient strength; the multi-groove cross-section fiber is made into filtering nonwoven of multilayer structure; filtering efficiency is effectively improved, and consumption of cross-flow filtering nonwoven is reduced; the advantage of deep filtering is also provided.

Description

【Technical field】 [0001] The invention relates to a filter non-woven fabric, in particular to a multi-layer fast filter non-woven fabric of cross-shaped special-shaped polyester fiber. 【Background technique】 [0002] The filtration process can be divided into four types: surface filtration, depth filtration, cake filtration, and cross flow filtration. At present, non-woven fabrics mostly use melt-blown non-woven fabrics or air-laid non-woven fabrics as filter materials, which are characterized by single-layer non-woven fabrics and irregular fiber distribution. The effect of surface filtering is good, but it needs a multi-layer stack to have the effect of deep filtering. [0003] Therefore, it is necessary to provide a new cross-shaped polyester fiber multi-layer fast filter non-woven fabric to solve the above problems. 【Content of invention】 [0004] The main purpose of the present invention is to provide a cross-shaped cross-section polyester fiber multi-layer rapid fil...
