Abstract

The invention discloses a collagen fiber reducing leather, belonging to the field of leather products. A collagen fiber reducing leather base cloth is utilized as a base cloth layer (1), a resin layer (2) is bonded and cured on the base cloth layer (1), and the surface of the resin layer (2) is distributed with animal skin-imitated skin lines (3). The performance of the collagen fiber reducing leather base cloth is close to that of animal skin, and the surface of the resin layer (2) is provided with the skin lines (3) and is fine and smooth, thus the collagen fiber reducing leather in the invention has good skin imitation effect and can be used for directly preparing final leather products such as leather garments, sofa, bags, leather shoes and the like.

Description

Collagen fiber reducing leather

Technical field

The present invention relates to a kind of leather and fur products, especially a kind of regenerated leather, i.e. collagen fiber reducing leather.

Background technology

Traditional regenerated leather all is that the leftover bits with various leathers and Animal Skin are ground into powder, then by adhesive or meldable fibre with powder-stuck, be pressed into the regenerated leather of monoblock.In recent years, occurred a kind of collagen fiber reducing leather base cloth on the market, it is that leftover bits with various leathers and Animal Skin extract collagenous fibres earlier, again collagenous fibres are woven into netted, pinprick reinforcement finished leather base cloth.The collagenous fibres of this collagen fiber reducing leather base cloth constitute three-dimensional network structure, with the collagenous fibres structural similarity in the skin corium of animal corium, thereby its mechanical property, hygroscopicity, gas permeability, anti-flammabilitys etc. are approaching with corium.But this collagen fiber reducing leather base cloth rough surface can not directly be used for making final leathercraft such as fur clothing, sofa, case and bag, leather shoes.

Summary of the invention

The purpose of this invention is to provide the good collagen fiber reducing leather of a kind of skin emulation effect, its surface is fine and smooth, can directly make final leathercraft such as fur clothing, sofa, case and bag, leather shoes.

For this reason, technical solution proposed by the invention is, a kind of collagen fiber reducing leather mainly constitutes base cloth layer by the collagen fiber reducing leather base cloth, and at this adhesive solidification skim resin bed above base cloth layer, and this resin layer surface is distributed with the dermatoglyph of emulation skin.

Therefore, the present invention with the approaching collagen fiber reducing leather base cloth of corium performance be base material, the very thin resin bed of adhesive solidification on it, the surface has the dermatoglyph of emulation skin again, thereby skin emulation effect is good, and the resin layer surface exquisiteness, such collagen fiber reducing leather can directly be made final leathercraft such as fur clothing, sofa, case and bag, leather shoes.

The present invention is further illustrated below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is the embodiment of the invention 1 a local section structural representation;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the another kind of embodiment section structure schematic diagram of dermatoglyph 3 among Fig. 2.

The specific embodiment

Embodiment 1 as shown in Figure 1 and Figure 2, base cloth layer 1 is the collagen fiber reducing leather base cloth, its collagenous fibres constitute space network, with the collagenous fibres structural similarity in the skin corium in the animal corium, its performance and corium are approaching.The resin bed 2 that adhesive solidification one deck is very thin on base cloth layer 1.The material of this resin bed 2 is generally polyurethane (PU), polyvinyl chloride (PVC) resin.Then, stamp the dermatoglyph 3 of imitative various animal corium on resin bed 2 surfaces with conventional release liners method.Because this dermatoglyph 3 is to be shifted by the dermatoglyph on the release liners to stamp, so this dermatoglyph 3 is smooth smooth pattern type dermatoglyphs 30.

Embodiment 2 is that with the difference of embodiment 1 embodiment of dermatoglyph 3 is different, i.e. the structure difference of dermatoglyph, and as shown in Figure 3, the dermatoglyph 3 of embodiment 2 is concave-convex type dermatoglyphs, promptly in resin bed 2 surface distributed projection 32 between one group of groove 31 and the groove 31 is arranged.This concave-convex type dermatoglyph is to suppress up by flower rolling impression method before the resin solidification of resin bed 2.Be carved with the groove and the projection of imitative animal corium dermatoglyph on the flower roller, behind the flower roll-in seal resin bed 2 solidified, resin bed 2 surfaces have just formed the concave-convex type dermatoglyph.

Claims

1. a collagen fiber reducing leather mainly constitutes base cloth layer (1) by the collagen fiber reducing leather base cloth, it is characterized in that: go back adhesive solidification skim resin bed (2) on described base cloth layer (1), and the surface distributed of resin bed (2) has the dermatoglyph (3) of emulation skin.

2. collagen fiber reducing leather according to claim 1 is characterized in that: described dermatoglyph (3) is the smooth smooth pattern type dermatoglyph (30) that is printed on resin bed (2) surface.

3. collagen fiber reducing leather according to claim 1 is characterized in that: described dermatoglyph (3) is the concave-convex type dermatoglyph, is made of the projection (32) between one group of groove (31) and the groove (31).
