[0004] In addition, CN101270530A discloses a fine-denier polyester filament knitted wiping cloth, which improves wiping performance and liquid absorption performance by using fine-denier polyester filament and combining with a texture structure with a concave-convex effect, but because it is a single layer Fabric, although the liquid absorption performance will be good, but the liquid retention will be relatively small, and the thickness of the wiping cloth is relatively thin, and the weight is small, which is easy to cause secondary pollution of solvents

Abstract

The invention discloses wiping cloth with a multilayered structure and processing method for the wiping cloth. An upper layer and a lower layer of the wiping cloth are made of ultrathin polyester fibers and common polyester fibers; a middle layer of the wiping cloth is made of common polyester fibers; the filament number of the ultrathin polyester fibers is 0.1-0.4dtex; the filament number of the common polyester fibers is 0.5-1.2dtex; the common polyester fibers are projected out of the upper surface and the lower surface of the wiping cloth; and the occupied area of the common polyester fibers are lower than the superficial area of the upper and lower surfaces of the wiping cloth. After the wiping cloth is purified, cut off and washed, the generation rate of particles with the diameters smaller than or equal to 0.5 micrometer in air can reach 16-2000 per m (2) (the diameters of the particles are smaller than or equal to 0.5 micrometer), and the generation rate of the particles in liquid can reach 1-1000 per cm (2). The wiping cloth has firm handfeel, and is excellent in liquid suction property and liquid retainability, excellent in wiping performance, simple in processing procedure and low in cost; and the wiping cloth does not have additional impurities.

Description

technical field [0001] The invention relates to a wiping cloth with a multilayer structure, in particular to a wiping cloth with a multilayer structure with high water absorption and water retention performance and a processing method thereof. Background technique [0002] In order to meet the requirements of different surfaces to be wiped and different degrees of cleaning, there are many types of wipes on the market, including non-woven fabrics, knitted fabrics, and woven fabrics. The fiber materials used include natural fibers, ultrafine synthetic fibers, and the like. For wiping cloths, everyone generally pays more attention to the wiping performance, but rarely pays attention to the water absorption and water retention performance. However, in the actual use process, the water retention capacity of the wiping cloth affects the scope of use of the wiping cloth. Most of the wiping cloths currently used are woven fabrics, single-sided woven fabrics or non-woven fabrics wit...
