Spunlaced nonwoven material for composite fiber curtain filtration and its processing method

Abstract

The invention discloses a composite fiber curtain filtering spunlaced nonwoven material and a processing method. Copet composite fibers, whitened polyester fibers, and superfine polyester fibers are realized through the following steps according to the mass ratio of 1.5:2.5:1: 1) copet composite fibers , whitened polyester fiber and superfine polyester fiber are mixed according to the mass ratio of 1.5:2.5:1; 2) After the mixed raw materials are mixed and loosened, they are transported to the air box carding machine by a fan; 3) The mixed fibers are carded into a web and transported to the spunlace machine; 4) spunlace processing on the spunlace machine; 5) dehydration treatment; 6) transfer to the dryer for continuous drying and curing after spunlace processing, wherein the curing temperature of the first oven is 160±3°C, and the second The curing temperature of the second oven is 170±3°C, and the speed is 45-50m / min; 7) Calendering finishing; 8) Slitting and packaging processes. The invention can achieve the effects of printing and dyeing, discounting, polishing, etc., and has the advantages of no slurry and low cost.

Description

technical field [0001] The invention relates to the non-woven material technology for curtain filtering, in particular to a composite fiber curtain filtering spunlace non-woven material and a processing method. Background technique [0002] Materials such as curtains and filters in the prior art mainly use sizing technology, followed by processing methods such as spunlace non-manufacturing fabrics, needle-punched non-woven fabrics, and materials woven from warp and weft yarns. [0003] In the prior art, spunlaced nonwoven fabrics with sizing are usually used, but this kind of product has pollution to the water quality environment caused by the slurry during processing, and at the same time, it is prone to microbial pollution in subsequent use, which is not conducive to environmental protection. Increasing the sizing process results in greater consumption of heat energy, and uneven sizing and uneven thickness, resulting in higher production costs. Materials such as curtains ...
