Material for manufacturing wet tissues for wiping transparent glassy hard surface and preparation method thereof

Abstract

A material for manufacturing wet tissues for wiping transparent glassy hard surface is composite non-fabric cloth composed of an upper fiber net layer, a middle absorption layer, and a lower fiber net layer; wherein the upper fiber net layer and the lower fiber net layer consist of fiber nets, the fiber nets are made of double-component fibers with a skin-core structure, the double-component fibers have been processed through a hydrophilic treatment, the fiber length of the double-component fibers is from 38 to 60 mm, and the fiber fineness of the double-component fibers is from 2 to 6 deniers; the middle layer is a layer of substance which is prepared from cellulosic fibers and thermoplastic fibers and has a high hygroscopic property; the double-component fibers is preferably any one component selected from polyethylene / polypropylene or polyethylene / polyester, wherein the material of the outer layer is polyethylene; and the thermoplastic fiber adopted in the absorption layer is the same polyethylene of the outer layer material of the double-component fibers. The material for wiping wet tissues has the advantages of good water-retention rate, good water diffusion performance, and low scrap dropping rate, can meet the requirements of no water-logging and wiping trace, quick drying, and no scrap dropping, and can be applied to the field of high-end wiping wet tissue. The invention also relates to a preparation method of the material for wiping wet tissues.

Description

technical field [0001] The invention relates to a material for wiping wet wipes, such as a material for wiping wet wipes on surfaces such as glasses and glass instrument panels, in particular to a material for wiping wet wipes on transparent glassy hard surfaces and a preparation method thereof. Background technique [0002] For wiping wipes on transparent glassy hard surfaces such as glasses and glass instrument panels, it is usually required to achieve the effects of wiping no water stains, scratches, quick drying, and no chipping. In order to achieve such effects, the materials used for wiping wipes must meet the requirements Under the condition of low liquid content (the weight ratio of the contained liquid to the liquid carrier material is ≤1.5 times), the liquid can fulfill the requirements of diffusion and wetting in the material. At present, the materials for this kind of wet wipes are mainly three kinds of materials: hot air / hot rolled nonwoven fabric, spunbond nonw...

AI Technical Summary

Problems solved by technology

At present, the materials for this kind of wet wipes are mainly three kinds of materials: hot air / hot rolled nonwoven fabric, spunbond nonwoven fabric and spunlace nonwoven fabric, all of which have their own advantages and disadvantages: hot air / hot rolled nonwoven fabric wipes Since the raw material is a chemical fiber treated with hydrophilicity, most of the liquid contained in it exists on the surface of the fiber, and only a small part is stored inside the fiber. The water retention is poor, and water stains will appear during the wiping process; spunbonded non-woven fabrics Because the woven fabric has a filament structure, it will not shed crumbs during the wiping process, but also because it is a chemical fiber, the water retention is poor, and there will be water stains when wiping; when the liquid content of the spunlace nonwoven fabric is less than 1.5 times, The liquid cannot effectively spread and infiltrate in it, and it is easy to cause uneven dryness and wetness

[0006] The above-mentioned wiping cloths have their own advantages and disadvantages. The ultra-fine fibers developed by various Japanese companies are reinforced into wiping cloths through spunlace or weaving. They have soft hand feeling and good wiping effect, but the cost of ultra-fine fibers is too high.

The polyester / wood pulp mixed spunlace wiping cloth developed in the United States has a relatively large loss rate of short fleece during the reinforcement process, and it will shed debris during the wiping process; German Freudenberg’s products have damage to fibers, and after coating Cloth treatment will affect the feel of the material; Chinese patent ZL200920200638.4 has inconsistent water retention and wear resistance on both sides of the material, which affects the performance of the product. Under the condition of low liquid content, it cannot be completely diffused and wet; introduced in Chinese patent 200820216683.4 The middle melt-blown non-woven fabric of the rag is ultra-fine chemical fiber, and its water absorption effect is not as good as cellulose fiber. During the wiping process, due to poor water retention, water stains will appear; the non-woven composite mechanism introduced in Chinese patent 01818625.4 Fiber materials need to be bonded first and then crushed, which increases the process and cost, and feels rough

The composite spunlace nonwoven fabric introduced in Chinese patent 201120513032.3 has poor water diffusion performance, and there will be water stains in the wiping process
