Abstract
A non-woven cloth made of bleached cotton is prepared through antistatic treating of bleached cotton, carding to become net, hydro-entangling and baking.
Description
The present invention relates to a kind of non-woven cloth made of bleached cotton and production method thereof.
Nonwoven fabric claims non-weaving cloth again, is textile industry nonwoven material production field.The process that the present invention adopts is a water thorn technology.
The bleaching cotton is that raw cotton fiber is taken off surperficial wax, fat etc., and the hygienic material fiber after bleaching is handled.Become the nonwoven fabric of the nonwoven of softness, moisture absorption through water thorn nonwoven processes; Be widely used in aspects such as hospital gauze, beauty and make-up, women sanitary articles and articles for babies.
Since bleaching cotton in the degreasing bleaching process fiber sustain damage, attenuate shorten, powerfully descend, fiber surface is sent out puckery and it is thread to form wadding, so in mixing shredding and carding process, easily produce static, fiber easily is damaged, form more cotton knot and combing, shift difficulty, can't ordinary production.Simultaneously because the influence of the oxidant of bleached cotton fiber in the degreasing bleaching process, there is small amount of fibers to degrade, hemicellulose is soluble in water and form the colloid flocculence, add and be damaged that the fiber that interrupts is quiet to be entered in the water when water stings, and to a certain degree will stop up water thorn liquid drugs injection hole (only for about 0.1mm) and has a strong impact on product quality even can't produce when accumulating to.The difficult combing of cotton short fiber in the world today, the global problem that in water thorn process, often causes water treatment system to stop up.
Because there is above-mentioned difficulties in the cotton spunlace non-woven cloth production of bleaching, so the cotton production of bleaching is world-famous puzzle always, its product just becomes the highly sophisticated products of spunlace non-woven cloth.
The production method that the purpose of this invention is to provide a kind of non-woven cloth made of bleached cotton.
Another object of the present invention provides a kind of non-woven cloth made of bleached cotton.
The object of the present invention is achieved like this: the production method that a kind of non-woven cloth made of bleached cotton is provided.The production method of described non-woven cloth made of bleached cotton comprises following scheme:
1, will bleach cotton and carry out antistatic treatment.Method is that the aqueous solution that adds 0.2% quaternary ammonium salt cationic surfactant of fibre weight sprays and mixes, and under air-tight state balance 24-72 hour, enter next procedure then.This antistatic additive chemical name is: trihydroxyethyl methyl quaternary amine methosulfate, contain free triethanolamine＜4.0%, and soluble in water, have hygroscopicity, can use with CATION, nonionic surface active agent.Fiber surface resistance after this product is handled can be from 10
10Be reduced to 10
6
2, transform big Bearded-needle knitted cloth.For making fiber can be carded to the filament state well, and can be shifted away smoothly, passed through long-term exploration and test, the specification of the big cylinder metal needle of carding machine has been done following improvement:
Simultaneously, the card clothing of corresponding combing part has been done corresponding adjustment:
It is very desirable to adjust the back effect, and fibre web shifts smoothly, cotton knot is few, damage is light, cloth surface evenness and brute force take an evident turn for the better.
3, transform water treatment system.Stop up the water needle plate problem for solving, we transform water treatment system, have increased efficient air-floating apparatus and sand formula filter in original water circulation system, to remove staple fibre and the gluey flocculate in the recirculated water.In air-floating apparatus, in reactive tank, add aluminium polychloride, NaOH, polyacrylamide etc. and can produce the auxiliary agent of flocculation, the attraction function of the micro-bubble (about 1 micron) that utilizes dissolved air again and produced, just can make organic impurities and jelly in the recirculated water be condensed into spongy flocculate, filter the less flocculate that flocculant is condensed by the sand formula again and aggregate into big flocculation piece, so that belt filter is removed.
By above improvement, the filter quality of water is greatly improved and guarantees, better solved the blockage problem of water thorn plate, guaranteed carrying out smoothly of product quality and production.
Former technical process is: grab cotton, mixed cotton, shredding, combing, water and sting, dry, batch, cut, when water stings through belt filter I, belt is filtered II, fine filtering, and then gets back to the water thorn.
Existing technical process is: antistatic treatment, grab cotton, mixed cotton, shredding, combing (changing card clothing), water and sting, dry, batch, cut, when water stings, float, add flocculant, the filtration of sand formula, belt worker, belt II, the smart filtration, and then get back to the water thorn through vapour.4, at last by dry, batch, cut, pack finished product.
Another object of the present invention is achieved in that
A kind of non-woven cloth made of bleached cotton is provided.Described non-woven cloth made of bleached cotton be bleached cotton fiber is carried out antistatic treatment, card clothing are remodeled, after the system reform of water thorn by mixed cotton, shredding, combing, water stings, dry, batch, cut, operation such as packing makes bleaching cotton spunlace non-woven cloth.
This process of producing product is pollution-free, sanitation and hygiene, and with back natural degradation, complete compliance with environmental protection requirements, soft, moisture absorption is breathed freely, close skin is comfortable.Can be directly used in hospital gauze, dressing, surgical material, high-grade face-cloth, articles for babies, cotton pads etc.
The invention will be further described below in conjunction with preferred embodiment of the present invention:
Embodiment 1: add with 100 kilograms of pure bleaching cotton short fibers 0.2 quaternary amine sun from from
Aqueous surfactant solution evenly sprays and mixes, and balance is 36 hours under air-tight state.
The big Bearded-needle knitted cloth of carding machine is transformed improved big Bearded-needle knitted cloth technical parameter
For: pin tooth depth 2.5mm, 18 ° of pin tooth angles, pin tooth density 550 tooth/inches.Original
Water circulation system in increase efficient air-floating apparatus and sand formula filter, add polymerization chlorine
The amount of changing aluminium is: 20-30 kilogram/1000 ton water.Will be through Antistatically treated bleaching
Combing in the cotton fiber feeding carding machine is stung, is dried, batches, cuts packing through water and makes
Bleach cotton spunlace non-woven cloth.
Embodiment 2: the viscose with 70% bleached cotton fiber and 30% produces nonwoven fabric by the method that embodiment 1 provides.
Embodiment 3: the polyster fibre with 70% bleached cotton fiber and 30% produces nonwoven fabric by the method that embodiment 1 provides.
