Abstract

The present invention relates to a making method of high bulkiness hot-air non-weaving fabric and products thereof. Firstly, fibre is made into composite fibre material with a surface layer and an inner layer, wherein the melting point of the inner layer is higher than that of the surface layer. Then the fibre material is carded into a fibre net layer through a cotton feeding device and a cotton carding device. The fibre net layer is sent to a hot-air device where the hot air makes the fibre with low melting point melted and stuck to form a bridge. A semi-finished product is curled and shaped. Pores of each fibre net layer of the product are arranged radially. Therefore, water can be diffused radially and be quickly absorbed, and is not easy to leak back. The high bulkiness hot-air non-woven fabric is especially suitable for being surface material of common sanitary material, and is not added with chemical binding agents. The high bulkiness hot-air non-woven fabric has low pollution.

Description

The high bulkiness hot-air non-weaving cloth goods

The present invention relates to a kind of high bulkiness hot-air non-weaving cloth goods, the particularly a kind of fusing point of composite fibre raw material and novel process for preparing of fiber properties (as fineness and crimpness) difference of utilizing, and do not add chemical adhesive in the method, make product, this product can be used as the surfacing of hygienic material, it has advantages such as highly-breathable and flexibility, is particularly suitable for doing the surfacing of general cotton wool and paper diaper.

The surfacing manufacture method of existing cotton wool and paper diaper, general all with the pressing mode or the hot blast Nonwovens of heat pressure roller, wherein, the pressing mode of heat pressure roller is that fiber B is given roll extrusion through roller (ROTTER) A1 and the A2 of array heating, and wherein roller A1 and A2 can use face wheel or engraving flower roller, form the hot pressing Nonwovens, but because of its finished product quality thinner, in case Boardy Feeling easily forms and bleeds back after pressing, flexibility is poor, and causes the uncomfortable even formation skin disease of user.The shortcoming that existing hot blast Nonwovens and hot pressing mode Nonwovens exist is summarized as follows:

1, the surfacing made of the pressing mode of heat pressure roller is not had a flexibility, uses sense of touch not good.

2, the surfacing made of the pressing mode of heat pressure roller, because of the pressure of roller is big, fiber surface forms thin slice, and tight exists, and hygroscopicity is poor.

3, the surfacing made of the pressing mode of heat pressure roller is because of combining closely between its fiber, so gas permeability is poor.

4, the surfacing made of heat pressure roller pressing mode not only is not easy to absorb, and bleeds back easily, can't reach the dry and comfortable effect in surface.

5, the hot blast Nonwovens can't provide the surfacing of high loft (BULK) in the past, so the scope of application is restricted.

6, hot blast Nonwovens surfacing, (Denier) is identical for the Yin Qidanni number, causes the hole of each fiber web layer certain, makes moisture content absorb easy formation the in back and bleeds back.

The purpose of this invention is to provide a kind of high bulkiness hot-air non-weaving cloth goods, the hole of its each fiber web layer becomes a radiation-like arrangement mode, and the diffusion that makes moisture content can be a radiation-like absorbs rapidly, and does not bleed back.

For achieving the above object, the present invention takes following design: this high bulkiness hot-air non-weaving cloth goods, it is a layer structure, the bulkiness of the composite fibre raw material of each layer employing, crimpiness and red Buddhist nun count difference, the hole of each fiber web layer becomes a radiation-like arrangement mode, described composite fibre raw material is divided into top layer and internal layer, and the fusing point of internal layer is higher than the fusing point on top layer, is the bridge formation that is formed by the lower surface fibre fusion effect of fusing point between the fiber in each layer.

Manufacture method comprises following step: at first fiber is made a composite fibre raw material with top layer and internal layer, the fusing point of its internal layer is higher than the top layer fusing point, again with fibrous raw material after feeding cotton device feeding, is fiber web layer by the comb and parallel cotton fibers prior to spinning device with its combing, utilize belt conveyor that fiber web layer is sent in the hot air apparatus, hot blast penetrates fiber web layer in the cycling hot wind furnace of hot air apparatus, make the lower fibers melt of fusing point, utilize this fusion effect to make and form the bridge formation combination between fiber, and be bonded together mutually, form the high loft semi-finished product, again through the batching apparatus coiling and molding.

The invention will be further described below in conjunction with accompanying drawing.

Fig. 4 is a goods schematic diagram of the present invention

Among Fig. 1, A1, the roller (Roller) of A2 heating, can use face wheel or engraving flower roller, B is a fiber, Fig. 2 A, Fig. 2, among Fig. 3, at first fiber is made composite fibre raw material 1 with internal layer 11 and top layer 12, the fusing point of its internal layer 11 is higher than the fusing point on top layer 12, again with fibrous raw material 1 after one feeds cotton device 2 feedings, 3 combings become a fiber web layer 4 by the comb and parallel cotton fibers prior to spinning device, this fiber web layer 4 can utilize belt conveyor 8 that fiber web layer is imported in the hot air apparatus 5, above-mentioned feeding unit 2 and comb and parallel cotton fibers prior to spinning device 3 can be according to the needs of reality use, feed several fibrous raw materials with different fibrous physical properties 1, they feed different feeding in the cotton device 2 respectively, perhaps adopt different mixed cotton modes to feed in the cotton machine respectively, to reach different effects, and fiber web layer 4 penetrates by the hot blast 52 in the cycling hot wind furnace 51 of hot air apparatus 5, can be with the lower fibers melt of top layer 12 fusing points, and this fusion effect of borrowing, make and form bridge formation (Crosslinkage) combination between fiber, and together bonded to each other, formation one has the semi-finished product 7 of high loft, relends and helps batching apparatus 6 coiling and moldings.

Ask for an interview Fig. 4, by the bulkiness (Bulk) of the composite fibre 1 of feeding itself, crimpiness (Crimp) causes high bulk effect, and because its red Buddhist nun's number (Denier) difference, cause the arrangement mode of 9 one-tenth one radiation-like of hole of each fiber web layer 4, make moisture can be the diffusion of a radiation-like, absorb rapidly, and be difficult for bleeding back, be particularly suitable for doing the surfacing of general hygienic material, the present invention pollutes low, very with practical value also because of adding chemical adhesive.

Advantage of the present invention:

1, flexibility is good: because it has high loft, so good skin-friendly and easypro is arranged Fit sense, be fit to do the surfacing of general hygienic material;

2, thickness is arranged: have more abundant sense of touch than general embossing adhesive-bonded fabric;

3, good permeability: the hole of each fiber web layer becomes the arrangement mode of a radiation-like, makes Moisture content can be the diffusion of radiation-like, so can absorb rapidly, is difficult for again bleeding back, and keeps the surface Dry and comfortable;

4, do not add any auxiliary agent, do not produce skin hypersensitivity, do not hinder skin.

Claims

1, a kind of high bulkiness hot-air non-weaving cloth goods, it is characterized in that: it is layer structure, the bulkiness of the composite fibre raw material of each layer employing, crimpiness and red Buddhist nun count difference, the hole of each fiber web layer becomes a radiation-like arrangement mode, described composite fibre raw material is divided into top layer and internal layer, and the fusing point of internal layer is higher than the fusing point on top layer, is the bridge formation that is formed by the lower surface fibre fusion effect of fusing point between the fiber in each layer.
