Embodiment Construction

[0025] A production method of spunlace non-woven fabrics, polyolefin fiber polypropylene fiber PP or polyester fiber polyester PET slices are fed into the hopper through a suction machine, enter a screw extruder, heat the slices to a temperature of 160-220°C, and pressurize to 5 The fluid in the molten state of ~20MPa uses a filter ≥ 200 mesh to filter out the impurities in the fluid and then flows into the spinning box, and enters the drafting air duct through the spinneret, and is cooled by 5 ~ 15°C freezing air. Perform drafting and cooling to make the spinning reach within 2 deniers, and the spun filaments reach the netting machine at a speed of >5000m / min, and spread into a uniform filament messy net. It is continuously output from the mesh curtain, sprayed and pre-wetted through the water spray pipe, and enters the spunlace machine for the first spunlace. The spunlace machine uses 2 to 3 spunlace heads with a pressure of 3 to 15MPa. After spunlace, the filament mesh has ...

Abstract

The invention discloses a method for producing spun-laced non-woven fabrics. The method is as follows: firstly, filaments are adopted for spinning, web-forming and primary spun-lacing; secondly, the filaments are added with a wood pulp lead-in recombiner for compounding after the primary spun-lacing; thirdly, secondary spun-lacing is performed after compounding; fourthly, squeezing and drying are performed; wood pulp is prepared on line into wet sheets by adoption of wet web-forming; the wet sheets are led into the recombiner and compounded with the filaments after the primary spun-lacing. The method has short production process flow and low equipment investment; the spinning and spun-lacing technology, the wood pulp wet web-forming technology and the spun-lacing compounding technology are effectively combined, thereby the speed is quick and the productivity is high. The filaments and the prior wood pulp are used as raw materials, and slicing, spinning and web-forming of the filaments and web-forming of the prior wood pulp are performed, and then spun-lacing is compounded; the whole production process fully utilizes water, energy and materials and the fabrics are produced at one step, thereby the production cost is low. The products produced have the strength of the filaments, the hydroscopic property of the wood pulp and the hand feeling of staple fiber spun-laced fabrics, do not fall off flock, are easy to degrade, and are novel products of 'green and environment-friendly' compound non-woven fabrics.

Description

technical field [0001] The invention relates to a production method of a nonwoven fabric, in particular to a production method of a spunlace nonwoven fabric. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. , Non-woven fabrics have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. Among them, the spunlace non-woven fabric uses the water needle flow with a pressure of 3 to 25Mpa to shoot the fiber net on the support net. Since the support net has a reflection effect on the water needle flow, the fibers move with the impact and rebound of the water flow. The fiber webs are entangled with each other t...
