Description
Technical field
The present invention relates to field of textiles, non-woven fabric manufacturing equipment and the side of specially a kind of silk and tencel hierarchical composite
Method.
Background technique
Natural silk is a kind of China as textile raw material and has used thousands of years, modern research shows that rich in more in silk
Kind of amino acid, water imbibition is that cotton obtains times or more, dry and comfortable, soft particularly suitable for women sanitary articles manufacture；
Tencel (tencel) fiber is the brand name of the LYOCELL fiber of Acocdis company of Britain production, is infused in China
Volume is Chinese entitled " tencel ", a kind of brand-new fiber which is produced as raw material through solvent spinning process using wood pulp.It has cotton
" comfort, " intensity " of terylene, " the luxurious aesthetic feeling " of wool fabric and " the unique sense of touch " of silk and " softness, which is hung down, to be fallen ", no matter
In the state of dry or wet, great toughness.In a wet state, it is the cellulose fiber that the first wet strength outclass cotton
Dimension.A hundred percent natural material, in addition the manufacturing process of environmental protection, allows life style, for this, to meet completely with conservation of nature environment
The demand of modern consumer is closed, and environmentally protective, can be rated as the green fiber of 21 century.Tencel is a kind of cellulose fibre,
Using solvent spining technology, do by force slightly below terylene, but be apparently higher than general viscose rayon, it is wet have than viscose glue by force significantly change
It is kind, there is very high rigidity, good washing dimensional stability (washing shrinkage is only 2%), hygroscopicity with higher, fiber
Cross section is round or oval, and gloss is graceful, and soft, drapability is good, and elegant property is good.In general: tencel includes 1
Have the flexibility 2 of cotton have terylene the warmth retention property laniferous of high-tenacity 3 but it be easy to be hardened under conditions of damp and hot, in cold water
To choose suede also bad.
Sanitary napkin used at present, paper diaper, contact one layer of skin be most critical layer of non-woven fabric, usually require that it
Water absorbing properties are good, and water guide speed is faster, dry and comfortable, soft.Mostly at present is to use chemical non-woven fabrics, also has and uses pure cotton non-woven fabrics on a small quantity.
But with regard to the pro-skin of product, antibacterial, anti-mite, antiultraviolet, the performances such as far infrared, and it is rich in non-silkworm from the aspects of amino acid
Silk does not belong to, however current manufacturing method is all single use silk, or is used in mixed way absorbent cotton+silk, cannot make its tool
There are the natural property of silk, and present manufacturing process higher cost, is not suitable for being widely applied.
Summary of the invention
The purpose of the present invention is to provide the non-woven fabrics manufacturing method of a kind of silk and tencel hierarchical composite, having both can be with
The advantages of keeping the natural property of silk, and reducing cost, can be widely applied, it is mentioned above in the background art to solve
Problem.
To achieve the above object, the invention provides the following technical scheme: the non-woven fabrics of a kind of silk and tencel hierarchical composite
Manufacturing equipment, including the first hello cotton machine, the first carding machine, the second hello cotton machine, the second carding machine, pressure cotton machine, spun-laced machine, dryer
And up- coiler, first feeds and is provided with the first carding machine below cotton machine, and second feeds and be provided with the second carding machine, day above cotton machine
Silk fiber feeds cotton machine and the first carding machine cards into tencel fibre web by first, and silk feeds cotton machine and the second carding machine by second
It is combed into the short fibre web of silk, tencel fibre web and the short fibre web of silk are successively by the spun-laced machine and dryer of setting, dryer side
It is provided with up- coiler.
A kind of non-woven fabrics manufacturing method of silk and tencel hierarchical composite, manufacturing method the following steps are included:
The first step takes tencel fiber, feeds cotton machine using first and grabs, and by the first carding machine cards together, keeps tencel fine
Now netted tencel fibre web is tieed up into, and equilibrium is continuously fallen on above a mobile lace curtaining.
Second step takes 100% mulberry silk, feeds cotton machine using second and grabs, and by the second carding machine together, makes the mulberry silk be in
The existing netted short fibre web of silk, and equilibrium is continuously fallen in above mobile tencel fibre web；
The short fibre web of natural silk and tencel fibre web of superposition are passed through pressure cotton machine by third step, the balanced mobile lace curtaining of continuation,
Keep cotton net pressurization thinning, then mobile by lace curtaining forward equalization.
4th step, by the short fibre web of the silk squeezed and tencel fibre web it is balanced by spun-laced machine, make two layers of cotton net
Non-woven fabrics is tangled into, then by drying machine drying, rolled machine is wound into silk non-woven fabric.
Preferably, according to step 3, by the short fibre web of silk before pressure cotton machine in upper, tencel fibre web under.
Compared with prior art, the beneficial effects of the present invention are: the non-woven fabrics of silk and tencel hierarchical composite of the invention
100% natural silk is covered on above tencel fiber by manufacturing method, with spun lacing technology, composite manufacturing at non-woven fabrics, by two
Person individually combs networking, is superimposed, and by spun-laced machine, manufactures into non-woven fabrics, becomes a kind of advanced composite material (ACM), both kept
The natural property of silk, and cost is reduced, it can be widely applied.
Detailed description of the invention
Fig. 1 is single unit system structure chart of the invention.
