Description

Moisture absorption is breathed freely, the preparation method of the Synthetic Leather spunlace non-woven cloth of antibacterial
Technical field
The present invention is to be related to the preparation method of spun lacing weaving material, especially moisture absorption, ventilative, antibacterial polyurethane synthesis The leather preparation method of spunlace non-woven cloth.
Background technique
Non-woven fabrics does not have latitude and longitude, cuts out and sews and is all very convenient, and light easy sizing, deep by manual fan Like.Because it is a kind of fabric for not needing spinning and weaving and being formed, only textile staple or long filament are determined To or random alignment, form fibre net structure, then reinforced using the methods of mechanical, hot sticky or chemical.
It not instead of by one by one yarns interwoven, woollen yarn knitting together, fiber directly passed through into the method for physics It is bonded together, so, when you take the viscous title in your clothes, it finds that, it is the end of a thread that can not taken out one by one.It is non- Woven cloths breach traditional weaving principle, and have that process flow is short, throughput rate is fast, yield is high, at low cost, purposes extensively, The features such as raw material sources are more.
Spinning building and non-woven fabrics are subordinate relation.The production technology that there are many manufactures of non-woven fabrics, wherein spun-bond process is it One of producing technology of non-woven fabrics (including spun-bond process, meltblown, Hot rolling, spun lacing method, now most of on the market is all with spinning The non-woven fabrics of bonding production)；Non-woven fabrics has terylene, polypropylene fibre, polyamide fibre, spandex, acrylic fibers etc. according to ingredient；Different ingredients have Completely different non-woven fabrics style.And spinning building, it is commonly referred to as terylene spun-bonded, polypropylene spunbond；And the style of both cloth is non- Very close to can just be determined by high temperature test.
Non-woven fabrics is a kind of non-woven cloth, it is that fiber is directly passed through gas using high polymer slice, staple fiber or long filament Then spun lacing is passed through in stream or mechanical networking, needle thorn or hot rolling are reinforced, the non-woven cloth finally formed by final finishing.Tool There is soft, ventilative and planar structure tencel product, advantage is not generate Soft flocks, it is tough, durable, silky soft, It is one kind of reinforcing material, and there are also the feelings of cotton to compare with cotton goods, the sack of non-woven fabrics is easily formed, Er Qiezao Valence is cheap.
Its shortcoming is that 1）Intensity and durability are poor compared with textile cloth；2）It cannot be cleaned as other clothes；3） Fiber arranges in certain direction, so being easy to split from right angle orientation etc..Therefore the improvement of production method is focused primarily on and is prevented In the improvement of division.（4）Water imbibition is poor；Bonded fabric product is rich in color, bright-coloured bright and beautiful, Eco-Fashion, widely used, beautiful big Side, pattern and style are all various, and light, environmentally friendly, recyclable, and the environmental protection by internationally recognized for ecology of preserving our planet produces Product.Suitable for agricultural film, shoemaking, process hides, mattress, child-mother-covering, decoration, chemical industry, printing, automobile, building materials, the industries such as furniture, And dress lining cloth, health care disposable surgical clothing, mask, cap, sheet, the disposable tablecloth in hotel, beauty, Saunas or even current The gift bag of fashion, fine work bag, shopping bag, advertising bag etc..Environment-friendly products, it is widely used, it is economical and practical.Due to its appearance It is similar to pearl, also known as pearl painting canvas.
Non-woven fabrics is by including chemical fibre and plant fiber etc. under conditions of using water or air as suspension media wet It is made on method or dry method paper machine, though without weaving therefore non-woven fabrics is called for cloth.Non-woven fabrics is environment-friendly materials of new generation, tool Have a good, air permeable waterproof of strength, environmental protection, flexible, non-toxic and tasteless, and it is cheap the advantages that.It is environment-friendly materials of new generation, is had Water repellent, it is ventilative, flexible, not combustion-supporting, nontoxic nonirritant, rich in color the features such as.If the material be placed in it is outdoor through natural decomposition, Its MaLS only has 90 days, disposed within to decompose in 8 years, and when burning is nontoxic, harmless, to free from environmental pollution, therefore environmentally friendly Come therefrom.
