Abstract

The invention provides a two-step production method of a compound wrinkling-style non-woven fabric, and the compound wrinkling-style non-woven fabric. The two-step production method comprises the following steps: S1, laying two layers of fiber webs on the upper surface and the lower surface of a low-melting-point mesh fabric, and strengthening through a spunlace non-woven process to form a compound spunlaced non-woven fabric substrate; S2, placing the compound spunlaced non-woven fabric substrate obtained in the S1 into a hot-air drying room to be processed so as to obtain the compound wrinkling-style non-woven fabric after the low melting mesh fabric shrinks in the longitudinal and transversal directions and the upper and lower fiber layers of which the melting point is higher than that of the mesh fabric have no change. The non-woven fabric prepared by the production method provided by the invention has the advantages of being high in dry and wet strength, excellent in water absorbability, and large in dust containing capacity. When the non-woven fabric is applied to the cleaning field, the intensity of the cleaning work is reduced, and valuable time and water resources are saved.

Description

Two-step production method of a kind of compound wrinkling formula non-weaving cloth and products thereof
[technical field]
The present invention relates to a kind of production method of compound wrinkling formula non-weaving cloth, be specifically related to two-step production method of a kind of compound wrinkling formula non-weaving cloth and products thereof.
[background technology]
Along with the raising of people's living standard, the hygienic requirements of people to the inhabitation such as family, restaurant, playground is also more and more higher.The cleaning tool rag that we often adopt, mop can not solve the problem run into, very well particularly to the cleaning of some corner health.And for all kinds of stupid stain on floor, it can not remove totally by mop completely.Simultaneously, common rag or mop surface are planes, dust containing capacity is limited, can be very fast full by fiber pore filling by dust when wiping, weaken dust removing effects, people need when clearing up repeatedly to rinse rag or mop, and the work back and forth of repetition not only makes cleaning become quite dull, and loses time and water.
[summary of the invention]
For the problems referred to above, the object of the present invention is to provide a kind of little for solving existing Clean-non-weaving cloth dust containing capacity, dry, wet strength is low, yielding compound wrinkling formula non-weaving cloth and production method thereof.
The present invention is achieved by the following technical solutions, provides a kind of two-step production method of compound wrinkling formula non-weaving cloth, it is characterized in that, comprise the following steps:
S1 adopts the production and processing of water acupuncture manipulation nonwovens process to go out composite water non-woven cloth base material;
The composite water non-woven cloth base material of step S1 is put in hot air baking room and processes by S2, and now the grid cloth of low melting point shrinks to generation in length and breadth when being heated, and fusing point is unchanged higher than the fibrage up and down of grid cloth, i.e. obtained compound wrinkling formula non-weaving cloth.
Especially, described step S1 is specifically according to following scheme implementation:
S11, on two carding machine spunlacing method production line, selects and has good hygroscopicity fibre as raw material, hygroscopicity fibre combing is formed upper and lower two layer web;
Grid cloth even, in the middle of two carding machines, is laid in the middle of two layer web by S12, and form a kind of three-decker lace curtaining body, the more fibroreticulate fusing point of fusing point of described grid cloth is low;
S13 is by lace curtaining body feeding spun-laced machine obtained for step S12, and after being combined into one under the effect of liquid drugs injection, drying, winding, make composite water non-woven cloth base material.
Especially, in described pair of carding machine water thorn production line, the one in selecting two comb one paving, two comb Shuan Pu, two comb directly to spread.
Especially, described hygroscopicity fibre net is short fiber of cellulose or adopts polyester staple fiber and short fiber of cellulose to mix in proportion, wherein the content of polyester staple fiber is lower than 30%, so while reduction water thorn production difficulty and holistic cost, can not reduce the water imbibition of non-weaving cloth.
Especially, described grid cloth material is polyethylene or the polypropylene of low melting point.
Especially, for the ease of the carrying out of water thorn production technology, the fineness of described short fiber of cellulose is 1.1-2.7dtex, length is 38-51mm.
Especially, in order to improve the outward appearance of non-weaving cloth, intensity and dust containing capacity, the grammes per square metre of described grid cloth is 8-12g/m 2, described fibroreticulate grammes per square metre is 30-60g/ ㎡.
Especially, the bake out temperature in described step S13 is 100-120 DEG C, and the temperature of this scope both can flash baking fleece, again lower than the softening point of grid cloth, ensure that composite non-weaving cloth flat appearance is even.
Especially, in described step S2, the temperature of hot air baking room is 130-180 DEG C, this temperature can ensure intermediate layer---the low-melting-point polyethylene of grid cloth or polypropylene material produce and shrink, and the fleece of levels is indeformable, thus make non-weaving cloth produce wrinkling effect; Vertical lateral shrinkage is 20%-40%, and shrinkage factor controls within the scope of this, and the appearance of non-weaving cloth can be made best; The compound wrinkling formula woven cloths grammes per square metre formed after shrinking is 45-80g/ ㎡.
The present invention also provides a kind of compound wrinkling formula non-weaving cloth prepared according to said method.
Compared to prior art, two-step production method of a kind of compound wrinkling formula non-weaving cloth provided by the invention and products thereof, the compound wrinkling formula woven cloths adopting the method to prepare is layered composite structure, namely water jet process compound two layer web is being adopted with the upper and lower surface of grid cloth, the three-decker be integrally formed, wherein fleece adopts the cellulose fibre of water imbibition excellence, comparatively fleece fusing point is low for the fusing point of grid cloth, cellulose fibre ensures the high-hydroscopicity of woven cloths, low melting point grid cloth ensures the intensity of woven cloths, both combine and ensure that woven cloths has good doing, wet strength and dimensional stability, simultaneously the rigidity of low melting point grid cloth is greater than fibroreticulate rigidity, and spot is removed in corner woven cloths being stretched into not easily enter at ordinary times or gap, wrinkling formula structure adds the dust containing capacity of woven cloths.
In sum, the manufacture cloth adopting production method of the present invention to prepare have dry, wet strength is high, water imbibition is good, and the advantage that dust containing capacity is large, is applied to cleaning applications, alleviates the intensity of clean work, saves valuable time and water resource.
