Abstract
The present invention discloses a dermal flocking leather, which comprises a surface layer, an interlayer and a bottom layer from top to bottom. The surface layer is a PU membrane, the interlayer is a PU foaming layer and the bottom layer is a base cloth. The present invention is characterized in that the bottom layer is also flocked with a scurf layer. The present invention also discloses a manufacturing method of the dermal flocking leather. The present invention adopts the an electrostatic flocking method to transplant discarded leather scraps and shreds onto wet-hair PU leather, thus changing waste into valuable, reducing environmental pollution, strengthening the stretch force of fabric and tear strength, and further increasing the durability of the product. The dermal flocking leather can be used in the products such as vamp, luggage bag and sofa which have high durability requirement. The present invention increases the friction force between the fabric and the adhesive layer, thus ensuring that the fabric is difficult to slide and increasing the practicality of the fabric. No matter seen from the surface or the back surface or felt by hand, the dermal flocking leather is extremely similar to dermis, thus increasing the dermis feeling and the aesthetic property, increasing the added value of the product, having high social value and economic value.
Description
[technical field]
The present invention relates to dermatine, relate in particular to a kind of novel dermal flocked pile leather and manufacture method thereof.
[technical background]
Existing dermatine imitation leather (the wet PU leather of sending out) is made of PU film, PU foaming layer, base cloth.Tensile force, the tearing strength of the dermatine imitation leather of this structure are all relatively poor, and lining is not suitable for the demanding products of durability such as vamp, case and bag, sofa.Fabric back is smooth, easily slides, and feel is poor, and is thinner, and kishke feel is not strong on the whole.Thereby cause added value of product low, selling price is low.
On the other hand, the leather leftover pieces that produced in the leather system factory production process are pressed into the imitation leather except that minority is used for wearing into the skin powder, and major part is fallen as garbage disposal, environment is caused significantly pollute.
[summary of the invention]
Purpose of the present invention is exactly in order to solve problems of the prior art, proposes a kind of dermis flocked pile leather and manufacture method thereof, can improve tensile force, tearing strength, has better durability, and strengthens feel, improves the product kishke feel.
For achieving the above object, patent of the present invention has proposed a kind of dermis flocked pile leather, comprises from top to bottom top layer, middle level and bottom, and described top layer is the PU film, and the middle level is the PU foaming layer, and bottom is a base cloth, it is characterized in that: also be implanted with the scurf layer on the described bottom.
As preferably, described scurf layer is 30.
As preferably, described PU film is 5, and the PU foaming layer is 60, and base cloth is 35.
As preferably, described scurf layer is planted on the base cloth by electrostatic spinning.
For achieving the above object, patent of the present invention has also proposed a kind of manufacture method of dermis flocked pile leather, may further comprise the steps successively:
Grind: the leather leftover pieces onal of collecting is ground, wear into scurf;
Screen cloth: the scurf after the grinding is selected through screen cloth;
Flocking: the scurf that screen cloth is crossed adopts the mode of electrostatic spinning to plant wet sending out on the PU leather, and the wet PU of sending out leather comprises that PU film top layer, PU foaming layer middle level and base cloth bottom, scurf plant on the base cloth that the wet PU of sending out removes from office;
Sanding: adopt roughing-up machine that the scurf layer is carried out sanding;
Post processing:, obtain the dermis flocked pile leather that softness has kishke feel with whole fabric washing back oven dry.
As preferably, the scurf layer is 30 in the flocking step.
As preferably, PU film described in the flocking step is 5, and the PU foaming layer is 60, and base cloth is 35.
The beneficial effect of patent of the present invention: the present invention handles the mode that adopts electrostatic spinning to discarded leather leftover pieces onal and plants wet sending out on the PU leather.Realized turning waste into wealth, reduced environmental pollution.The tensile force, the tearing strength that have strengthened lining strengthen, thereby have strengthened the durability of product, can be used in the product that vamp, case and bag, sofa etc. are had relatively high expectations to durability.Increased the frictional force of lining and adhesion layer, thereby lining be difficult for to be slided, strengthened the practicality of lining, the surface sees that the feel of still seeing from the back side or touching with hand is all very similar to corium, has strengthened kishke feel and aesthetic property.Improve value-added content of product, had very high society and economic worth.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
[description of drawings]
Fig. 1 is the structural representation of dermis flocked pile leather of the present invention;
Fig. 2 is the process chart of the manufacture method of dermis flocked pile leather of the present invention.
[specific embodiment]
Consult Fig. 1, dermis flocked pile leather comprises from top to bottom top layer 11, middle level 12 and bottom 13, and described top layer is the PU film, and the middle level is the PU foaming layer, and bottom is a base cloth, also is implanted with scurf layer 14 on the described bottom 13.Described scurf layer 14 is 30.Described PU film is 5, and the PU foaming layer is 60, and base cloth is 35.Described scurf layer 14 is planted on the base cloth by electrostatic spinning.For richness, the skin sense that strengthens whole leather fabric, the present invention just carries out the flocking of corium scurf on the back side base cloth of wet PU leather on the basis of former imitation leather (the wet PU leather of sending out).Thereby whole fabric practicality, durability and aesthetic property are strengthened greatly.
Consult Fig. 2, the manufacture method of dermis flocked pile leather may further comprise the steps successively:
Grind 1: the leather leftover pieces onal of collecting is ground, wear into scurf.
Screen cloth 2: the scurf after the grinding is selected through screen cloth, sieves below the order number that becomes to need.
Flocking 3: the scurf that screen cloth is crossed adopts the mode of electrostatic spinning to plant wet sending out on the PU leather, and the wet PU of sending out leather comprises that PU film top layer, PU foaming layer middle level and base cloth bottom, scurf plant on the base cloth that the wet PU of sending out removes from office; The scurf layer is 30, and the PU film is 5, and the PU foaming layer is 60, and base cloth is 35.Adopt the technology of electrostatic spinning simple, effective.
Sanding 4: adopt roughing-up machine that the scurf layer is carried out sanding.Reach the effect of corium reverse side.
Post processing 5:, obtain the dermis flocked pile leather that softness has kishke feel with whole fabric washing back oven dry.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
