Description
Technical field
What the present invention relates to is nonwoven and manufacture field thereof, more specifically says a kind of compound nonwoven cloth and production equipment thereof with transverse elasticity.
Background technology
Nonwoven is by comprising that the raw material such as chemical fibre and string making under the condition of suspension media using water or air, though name is called cloth, but it can not be weaved, nonwoven is environment-friendly materials of new generation, there is powerful good, air permeable waterproof, environmental protection, pliable and tough, nonpoisonous and tasteless, and the advantage such as low price. if this material is placed in outdoor through natural decomposition, its MaLS only has 90 days, be placed in and indoorly in 8 years, can decompose, nontoxic when burning, tasteless, and without any material of leaving over, thereby free from environmental pollution, therefore environment protecting is splendid, due to these advantage thing features, nonwoven has obtained using widely, can be applicable to agricultural film, shoemaking, mattress, child-mother-covering, decorate, chemical industry, printing, automobile, the every profession and trade such as building materials and furniture, can be used as dress lining cloth, health care disposable surgical clothing, mouth mask, cap, sheet, the disposable tablecloth in hotel, beauty treatment, the gift bag of Saunas and extremely current fashion, the products such as fine work bag or shopping bag.
And in the application of these nonwoven, wherein a lot of fields have all proposed flexible demand to nonwoven, such as disposable glove, diaper side band etc. need to be followed the field of human motion, and existing common non-woven fabric is not have spring function, can not meet the demand of this series products. The above-mentioned shortcoming and defect existing in order to overcome prior art, the staff of this area also develops kind of a multiple tool nonwoven springy, as Chinese patent application publication No. is: CN102501484A, disclosed a kind of high-elasticity non-woven fabric and manufacturing equipment thereof, this technical scheme provides a kind of elastomeric nonwoven, this nonwoven is pasting one deck resilient middle layer by two-layer common nonwoven cloth clamp and is forming, intermediate layer is formed by hot melt by TPUE, and the compound nonwoven cloth combining possesses certain elastic performance. But the middle elastic layer of this nonwoven is formed by hot melt, the meldable fibre bar forming can not be evenly arranged, so the elastic force forming is also inhomogeneous, on the other hand, the meldable fibre bar forming distributes in longitudinal arrangement mode, so the compound nonwoven cloth of its formation does not have transverse elasticity, the nonwoven needing in the products such as diaper side band is very high to the requirement of transverse elasticity, so the elastic force nonwoven that in actual applications, prepared by this scheme needs the special dimension of transverse elasticity to be difficult to obtain practical application for nonwoven.
For the research and development of nonwoven that need transverse elasticity, Chinese patent Granted publication number is: the disclosed a kind of elastic composite nonwoven fabric of CN202592834U, the structure of this compound nonwoven cloth comprises intermediate thin rete, the first nonwoven layer and the second nonwoven layer, intermediate thin rete is folded between two-layer nonwoven layer, and be provided with some equidistant elastic spaces in the first nonwoven layer and the second nonwoven layer, utilize this elastic space to make this compound nonwoven cloth possess certain transverse elasticity. But this transverse elasticity is limited by this equidistant space, and elastic force limits to very much, is difficult to be applied in actual production process.
