Problems solved by technology

For high-production nonwoven carding machines, there are often several layers of cotton webs that need to be stripped and then superimposed. At this time, if the traditional stripping device is used, the following disadvantages will occur: (1) Each layer of cotton web needs a stripping roller or Apron, too many machine parts, cost increase
(2) Cotton stripping roller or apron stripping device has too much draft on the cotton web, which seriously affects the quality of non-woven products

Embodiment Construction

[0019] A production process of spunlace composite high-performance polyphenylene sulfide fiber filter material, which uses polyphenylene sulfide fiber and glass fiber base cloth as raw materials, and the raw materials are inspected--weighing and feeding--feeding into the long curtain-- Cotton blending-fine opening, layering is carded separately by the first carding machine and the second carding machine, and then laid on the cross-lapper respectively, then unwinding-lamination-prewetting, and spunlace by multi-pass spunlace machine - Dehydration, drying - coiling.

[0020] This process links the equipment involved in the production process--carding machine, cross-lapper and final product weight detection to form a comprehensive automatic control closed-loop system. Feedback to the computer, the computer controls to change the process parameters of the lapper and carding machine, automatically compensates and adjusts the uniformity of the fiber web, so as to ensure the uniformi...

Abstract

The invention relates to a process for producing spunlaced composite high-performance polyphenylene sulfide fiber filtering material, belongs to the fibrous raw material textile production technology field. The process uses polyphenylene sulfide fiber as raw material, has the following steps: processing raw material by checking, weighing, feeding, feeding into long certain, mixing cotton and fine loosing; layering and carding respectively by a first carding machine and a second carding machine; putting respectively into mesh placing machine for placing mesh; debatching, congruent, superposing and prewetting; spunlacing by a plurality of spunlacing machine, dewatering, drying and reeling. The advantages of the invention is that: the invention adopts polyphenylene sulfide high-performance fiber as raw material, the raw material is adapted to high efficient high speed carding production for its self physical and chemical properties, structure and adaptability to meshing and reinforcing process; improves spunlacing entanglement effect to fiber; improves the mechanical strength of spunlaced composite filtering material significantly, and ensures the end product to achieve excellent mechanical properties, filtering quality and chemical resistance property.

Description

technical field [0001] The invention relates to a production process of a spunlace composite high-performance polyphenylene sulfide fiber filter material, and belongs to the technical field of using fiber raw materials to manufacture textiles. Background technique [0002] The nonwoven carding machine in the traditional production process has two main carding units, the main cylinder and the breast cylinder, and there are generally one to two transfer rollers between the main cylinder and the breast cylinder, so the breast cylinder is transferred to the main cylinder The amount of fiber in forests is limited. The traditional carding machine web stripping device adopts mechanical stripping, and the stripping of the cotton web is realized through stripping rollers, aprons or chopping knives. For high-production nonwoven carding machines, there are often several layers of cotton webs that need to be stripped and then superimposed. At this time, if the traditional stripping dev...
