Problems solved by technology

[0003] At present, the direct-laid wood pulp composite spunlace wiping cloth developed by a few domestic spunlace companies has the disadvantages of low lateral strength (not yet reached 60N / 5CM) and easy deformation, which is not conducive to deep processing and the application of high-end wiping cloths.
However, the vertical and horizontal strength ratio of the wood pulp composite spunlace wiping cloth in the prior art is above 3.6:1, the transverse strength is low, the elongation is too large, and it is easy to deform

preparation example Construction

[0030] A method for preparing a composite spunlaced nonwoven fabric of the present invention, the 100% polyester fiber is sequentially fed through unpacking, coarse opening, fiber mixing, fine opening, carding, cross-lapping, drafting and the first Spunlace to obtain a non-wiping layer, and then composite the non-wiping layer with a wiping layer composed of 100% wood pulp paper material for the second time to obtain a composite spunlace nonwoven fabric.

[0031] The beneficial effect of the preparation method of composite spunlace nonwoven fabric of the present invention is:

[0032] (1) Feed 100% polyester fiber through bale opening, coarse opening, fiber mixing, fine opening, carding, cross-lapping, drafting and the first spunlace, so that the CD transverse strength of the non-wiping layer obtained Up to 100N / 5CM has the characteristics of high strength, and then the wiping layer and the non-wiping layer are spunlace compounded for the second time, so that the longitudinal a...

Embodiment 1

[0044] The composite spunlace nonwoven fabric of this embodiment includes a wiping layer and a non-wiping layer, the wiping layer is made of 100% wood pulp paper material, and the non-wiping layer is made of 100% 1.2D×38MM polyester fiber material, so The non-wiping layer is made of 100% polyester fibers through cross-laying and the first water entanglement, and the wiping layer and the non-wiping layer are combined through the second water entanglement. The weight of the wiping layer is 38±2g / m 2 ; The weight of the non-wiping layer is 30±3g / m 2 , the weight of the wiping layer and the non-wiping layer after the second spunlace composite is 68±4.5g / m 2 .

[0045] The preparation method steps of the composite spunlace nonwoven fabric of the present embodiment are as follows:

[0046] (1) Preparation of non-wiping layer: 100% 1.2D×38MM Jiangsu Yizheng spunlace special fiber is fed through bag opening, coarse opening, fiber mixing, fine opening, carding, laying and drawing to...

Abstract

The invention relates to a composite spunlaced nonwoven fabric which comprises a wiping layer and a non-wiping layer, wherein the wiping layer is formed by 100% wood pulp paper material; the non-wiping layer is formed by 100% polyester fiber material; the non-wiping layer is manufactured by carrying out cross lapping and spunlace on the 100% polyester fiber; the wiping layer and the non-wiping layer are compounded together by spunlace. The invention also relates to a preparation method of the composite spunlaced nonwoven fabric. The ratio of the longitudinal strength to the transverse strength of the composite spunlaced nonwoven fabric is controlled to be less than 2: 1, and the longitudinal strength is close to the transverse strength, so that the composite spunlaced nonwoven fabric is not easily deformed; the CD transverse strength of the composite spunlaced nonwoven fabric reaches up to 100N / 5cm; the composite spunlaced nonwoven fabric is thin, does not drop scraps, and is soft after absorbing moisture and good in wiping property; the composite spunlaced nonwoven fabric is good in wear resistance, the wiping efficiency is increased by 20%, the service life is prolonged by 30%, and the service performance of wiping cloth is effectively improved.

Description

technical field [0001] The invention relates to a nonwoven fabric for industrial wiping, in particular to a composite spunlace nonwoven fabric and a preparation method thereof. Background technique [0002] Spunlace non-woven fabric production technology is a new type of non-woven fabric technology. It uses high-pressure water to spray and puncture the fibers placed on the supporting mesh curtain, so that the fibers are affected by the reflected water needles in all directions. And intertwined and reinforced into cloth. Since the appearance and performance of spunlace nonwovens are the closest to traditional textiles, and have many characteristics such as good hand feeling, softness, and not easy to fall off, the production technology of spunlace nonwovens has developed rapidly in the past two decades, and the annual production has reached 309,000 tons. At present, there are 190 domestic spunlace production lines in China, including more than 30 imported lines, with a tota...
