Description

High-performance dry-process paper-cotton compound non-woven fabric and preparation method thereof and utilization

Technical field

The invention belongs to textiles and non-weaving cloth technical field, more specifically relate to a kind of high-performance dry-process paper-cotton compound non-woven fabric and preparation method thereof and utilization.

Background technology

Along with the reinforcement of the mankind to the raising day by day of its own existence environment understanding of importance and the ecological awareness, environmental consciousness, green product has become the human focus of paying close attention to of 21 century.

In recent years, the whole world starts the green consumption notion of " returning natural ", and people's consumption orientation has been produced increasing influence.Follow " pollution-free food " closely before, " green textiles ", " ecological textile " have become the trend and research focus of the current world.

Textiles and non-weaving cloth and people's social and economic activities are closely related; A big series products that closely contacts with conducts such as goods such as underwear, clothes, bedding, panty liner, baby diaper, sanltary towel, all kinds of cloths for wiping or dusting and the mankind; Be regarded as human second skin and first living environment, directly have influence on the health and safety of the person.Therefore, the pollution from textiles is caused more pay close attention to widely and watch out for.The rules of some relevant environment protection requirement of developed country are more and more, and its measuring means and standard-required are also increasingly high.

Under these circumstances; Each state all helps environmental protection in active development, production, helps the product of health; High-performance dry-process paper-cotton compound non-woven fabric is the international nonwovens industry new product of focus development in recent years; It not only has good brute force and the uniformity, quality softness, surfacing, absorbability is good; Have more good biological degradation function, meet the requirement of environmental protection and recycling economy, be applicable to all kinds of medical and healths, daily living article, all kinds of special cloth for wiping or dusting, paper for cleaning or the like.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, a kind of high-performance dry-process paper-cotton compound non-woven fabric that uses in extensive range, excellent performance, environmental protection is provided.

Another object of the present invention is to provide the preparation method of this high-performance dry-process paper-cotton compound non-woven fabric.

The present invention also has a purpose to be this high-performance dry-process paper-cotton compound non-woven fabric is applied to new medical dressing; Sanltary towel, protection pad, baby diaper, adult-incontinence articles, the civilian and industrial fields such as cleaning material of promptly abandoning material and high optics precision instrumentation, most advanced and sophisticated machinery and being used for national defence and special high-tech area.

For achieving the above object, the present invention has taked following technical scheme:

High-performance dry-process paper-cotton compound non-woven fabric has layer structure, and two-layer up and down is the viscose staple fibre layer, and the centre is the pulp layer.

The preparation method of high-performance dry-process paper-cotton compound non-woven fabric comprises the steps:

After a, the carding machine combing of short rayon fiber, form two-layer fibre web up and down through opening or cleaning and particular design;

B, lower floor's fibre web fed distance weak point, feeding earlier is combined into the net system;

C, pulp feed behind air lay and are combined into the net system, and topped on lower floor's fibre web, form range upon range of compoundly, and the upper strata is the pulp net, and lower floor is the viscose glue net;

D, upper strata fibre web feed the net system that is combined into immediately, and be topped on the pulp fibre web, forms three folded layer by layer (viscose glue, pulp, viscose glue) composite constructions;

E, three folded layer by layer fibre webs are fed composite spunlaced machine system, carry out repeatedly Hydroentangled;

Range upon range of blank behind f, the water thorn is dried through dryer;

Blank after g, the oven dry is cut, and coiling obtains final " sandwich " formula high-performance dry-process paper-cotton compound non-woven fabric then.

The high-performance dry-process paper-cotton compound non-woven fabric of gained of the present invention can apply to new medical dressing; Sanltary towel, protection pad, baby diaper, adult-incontinence articles, the civilian and industrial fields such as cleaning material of promptly abandoning material and high optics precision instrumentation, most advanced and sophisticated machinery and being used for national defence and special high-tech area.

Compared with prior art, the present invention has following beneficial effect:

1. key of the present invention is to adopt the carding equipment of particular design; Reach with the combing simultaneously of a combing function and go out two-layer fibre web up and down; Utilization is the difference of fibre web fed distance up and down; To become the pulp net of net through the air lay system, and be compounded in the centre of fibre web up and down, formation three is the hydro-entangled non-woven fabric of folded (viscose glue, pulp, viscose glue) composite construction layer by layer.This project product not only has the excellent biodegradability ability, meets the requirement of environmental protection and recycling economy, is applicable to all kinds of medical and healths, daily living article, all kinds of special cloth for wiping or dusting, paper for cleaning or the like.

2. water stings fixed employing pulley type and platform-type structure combining form, and high-pressure hydraulic pump adopts the three-throw ram pump of import function admirable, and discharge pressure is big, can realize more effectively that the water thorn of composite web is fixed.Compare with light water thorn concretion technology, tangle, bonding effect is good, the product brute force improves greatly, and surfacing is stable and reliable for performance, energy efficient.

3. light water thorn production line water treatment system adopts single-stage to filter, and the purification of water quality degree is poor.And the comprehensive all in the world processing methods at present of this project water treatment system are optimized combination; Unique design thinking reasonable disposition according to multistage filtering; Have the advantages that treating capacity is big, effect is splendid, help production high-performance, abrasive hydro-entangled non-woven fabric product.The recycling of industrial water helps cleaner production and reduces production costs.It is compound that produced in conventional processes product needed of the present invention uses the production equipment more than two to carry out, and the present invention only need use one of carding system equipment that the clean holy Industrial Co., Ltd. in Taiwan produces just can come out direct with following short fiber layers combing and the pulp layer carries out compound with going up short fiber layers.

4. light water thorn nonwoven fabric production line generally adopts drying cylinder collision type drying, the product Boardy Feeling, and dry efficiency is low.And this project adopts efficient hot-air through type circulation drying system that the fibre web after the water thorn is compound is carried out highly-effective drying, has both improved dry efficiency, has saved the drying energy consumption, can guarantee that again the hydro-entangled non-woven fabric product has good hand feeling.

5. utilize pulp and fibre web water thorn compound; Its product is moisture-penetrable ventilated, soft, do not fall flock; And wood pulps is cheap; 50/50 wood pulps/terylene Hydroentangled product is more much lower than the production cost of 30/70 traditional terylene/viscose glue Hydroentangled product, and the wood pulps fiber can evenly be distributed in the chemical fiber web effectively, and the key property of product is constant.Therefore, pulp water jet bonding composite non-woven cloth is the desirable raw material of cloth for wiping or dusting, wet towel, the medium usefulness of baby wipe.
