Description
Technical Field
The utility model belongs to the technical field of non-woven fabrics technique and specifically relates to a melt-blown spunlace composite non-woven fabric.
Background
The thermal conductivity of polypropylene is the lowest of all fibers, and is generally 2.1-4.2X 10-4 cal/cm. DEG.s. As a thermal insulation material, better than wool, polypropylene (polypropylene) is the chinese trade name for isotactic polypropylene fibers. Polypropylene is particularly lightweight, having a density of only 0.91g/cm3, and is currently the lightest of all synthetic fibers. Polypropylene has high strength and good chemical corrosion resistance, but polypropylene has poor heat resistance, light resistance and dyeing property.
The fiber web is sprayed by adopting a plurality of strands of superfine water jets generated by high pressure, and is commonly called as high-pressure water needle. After the water needle penetrates through the fiber web, the water needle is rebounded by the supporting net curtain and penetrates through the fiber web again, and therefore, the fibers in the fiber web are displaced, penetrated, tangled and cohered under the hydraulic action of the high-speed water needle penetrating in different directions, and the fiber web is reinforced.
With the gradual improvement of the quality of life and health care consciousness of people, the melt-blown spunlaced composite non-woven fabric becomes an ideal necessity in the daily life process of people, the market demand of the non-woven fabric is very large, various functional products are well favored by people, for example, gauze made of polypropylene (polypropylene) and the like have the advantages of no adhesion to wounds and no toxicity, and therefore, the non-woven fabric can be widely applied to the medical industry.
The section and the longitudinal form of the polypropylene fiber are similar to those of terylene; the alkali resistance and the acid resistance are good, and the coating is insoluble in common organic solvents, does not mildew or damage; the pure polypropylene fiber has poor moisture absorption capacity, almost no moisture absorption, a wicking effect, good capillary action, nearly zero moisture regain under standard conditions, no obvious change of performance in a dry and wet state, and poor spinnability of the pure polypropylene fiber; the strength, the elongation at break, the elasticity and the wear resistance are superior to those of cotton fiber and are close to those of terylene; poor dyeing performance and incomplete dyeing chromatogram; the sun resistance is poor, the aging is easy, and static electricity is easy to accumulate during processing; the polypropylene fiber has higher strength and initial modulus, and is close to the polyester fiber; the density is low, so that the variety with the lightest specific gravity in common synthetic fibers; the heat conductivity is low, and the heat preservation is good; the wear resistance is good, the flat wear resistance is close to that of chinlon, but the bending wear resistance is slightly poor; the polypropylene has lower glass transition temperature and unstable heat setting effect.
The polypropylene fiber has the advantages that the polypropylene fiber is suitable for producing medical and sanitary materials, gauze made of polypropylene fiber has the advantages of no adhesion to wounds and no toxicity and can be used for medical purposes, the polypropylene fiber is not only used for weaving carpets and some special industrial permanent magnets, but also can be used for processing civil engineering cloth and artificial lawns, the price of the polypropylene fiber is lower, the polypropylene fiber can be used for producing blended weaving materials of cotton and viscose fiber, and the polypropylene fiber can be used as raw materials of filter cloth and carpet, and can also be used for producing the cotton and viscose fiber, and the polypropylene fiber has the advantages of poor physical properties of filter cloth and carpet, including poor longitudinal section strength of polypropylene fiber, good moisture resistance, good chemical resistance, good moisture resistance, good chemical resistance, good moisture resistance, good.
When used as a wiping material for wet wipes, the polypropylene melt-blown nonwoven fabric alone is inferior in water absorption. If a spunlace nonwoven produced by a parallel-laid method is used, it is easily deformed and the shape retention is not good. If the spunlace nonwoven fabric produced by the cross lapping mode is used, the production speed is slow and the cost is high.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
This embodiment will be described in detail with reference to fig. 1. The embodiment relates to a melt-blown spunlace composite nonwoven fabric which comprises a fiber assembly I1 and a fiber assembly II 2, wherein the fiber assembly I1 and the fiber assembly II 2 are reinforced by spunlace. The fiber assembly I1 is PP melt-blown non-woven fabric, and the fiber assembly II 2 comprises a cross-lapping fiber layer 21 and a parallel-lapping fiber layer 22. The cross-laid fiber layer 21 is adjacent to the fiber assembly 1.
The grammage of the PP meltblown nonwoven fabric used is in the range of 10-30 grams per square meter and the diameter of the PP fibres used is 0.5-1.5 μm. In this example, the raw material used for the cross-lapping fiber layer 21 in the fiber assembly 2 is polyester fiber with a specification of 38mm × 1.56dtex, and the raw material used for the parallel lapping fiber layer 22 is sea-island type microfiber or orange petal type microfiber. After the spunlace reinforcement, the non-woven fabric forms an ultrafine fiber layer, and the wiping dirt-removing capacity is increased. The impact of the superfine fiber by the water jet high pressure water flow can make the sea part of the island superfine fiber be dispersed and leave the island part. The sea-island type ultrafine fiber used had a fineness of 1.56dtex, in which the number of islands was 36, 37 or 51, and the proportion of the "sea" portion was 20%. In this example, the cross-laid fiber layer has a grammage of 20-40 grams per square meter and the parallel lay has a grammage of 10-20 grams per square meter.
Forming a cross lapping fiber layer 21 by polyester fibers through a carding machine and a cross lapping machine, wherein the longitudinal and transverse strength of the cross lapping fiber layer 21 is 1.1-1.5: 1. directly forming a net by superfine fibers through a carding machine to form a parallel lapping fiber layer 22, wherein the longitudinal and transverse strength proportion of the parallel lapping fiber layer 22 is 4-6: 1. the longitudinal strength is greater because the fibers combed by the carding machine are more oriented in the direction of the carding machine. This is also the reason for the poor shape retention of parallel-laid nonwoven fabrics.
The cross-lapping fiber layer 21 and the parallel-lapping fiber layer 22 are overlapped in such a manner that the parallel-lapping fiber layer 22 is on the upper side and the cross-lapping fiber layer 21 is on the lower side, thereby forming a fiber assembly 2. And then the fiber aggregate II 2 is superposed with the PP melt-blown non-woven fabric, and the cross lapping fiber layer 21 is contacted with the PP melt-blown non-woven fabric. And the superposed fiber aggregate I1 and fiber aggregate II 2 are subjected to spunlace reinforcement and drying to form the non-woven fabric related to the embodiment. After testing, the ratio of the longitudinal strength to the transverse strength of the finally formed non-woven fabric is 1.5-2: 1, has good shape-preserving capability.
