Description

A kind of method of making velour with defective leather

[technical field]

The invention belongs to the leather processing field, particularly be a kind of method that defective leather leather is processed into suede garment leather, cashmere hats and shoes luggage leather.

[background technology]

At present, after the animal skin tanning, what dermatotome was complete can make smooth leather through ornamenting, and velour is made in also can coming the hide fiber pull-up of the complete no rhabdion of dermatotome.But animal skin forms in growth various hinder in sore joint trace and the machinery in stripping, the processing of tanning, the wound that chemical action causes residual, leather more than 50% belonged to have broken hole, lack piece, breach, retouch indenture wounds leather such as cutter, scuffing, numb plate, with residual leather in chaff plate, the poor plate etc., and cut open time leather in two, three layers of meat getting the upper leather mouth.The disable area of these leathers limits whole skin and can't make smooth leather or the velour of finishing.Therefore, how processing the defective leather leather is a technical barrier that exists in the leather processing technical field.Solve this technical barrier, common way is to paste one deck artificial rust on surface, makes the veneer leather.But this technology is only feasible to the intact leather of gined cotton, to gined cotton broken hole arranged, lack piece, breach, the wounded or disabled skin of retouching cutter, wound etc. then is difficult for implementing.Because any wounded or disabled vestige on skin surface still can be reflected to the veneer surface and come up behind the veneer.The method of " tanning chemistry and technology " the 610th page of proposition that another kind of way such as Chengdu Univ. of Science ﹠ Technology and northwest light industry institute collaborate, it is that the leather bits are pulverized, and with Chinese workers' material hide fiber is disperseed, add resin again after pressure grind into regenerated leather.Select materials and only be limited to the good-for-nothing leather of reticular layer bits but implement this technical scheme, have the leather bits of grain layer, then inapplicable because of being separated into fiber.Go out like this to remove from office in two or three layers of good-for-nothing meat outside the bits, other wounded or disabled leather then all can't be processed into regenerated leather with this technology because of having grain layer.

[summary of the invention]

Problem in view of the known technology existence, purpose of the present invention just provides a kind of method of utilizing defective leather processing velour, it can grind moulding without pulverizing, loosen collagen fibre, interpolation resin, pressure, these complicated technologies, but be after the basis is carried out and simply repaired with former defective leather, with the flocking of skin flocking technology, change can be covered up the wounded or disabled vestige of repairing effectively, obtains the same suede garment leather of a kind of and intact leather flocking, shoes and hats luggage leather.For achieving the above object, the present invention takes following scheme to realize: the broken hole of hindering skin, lack piece, breach with shear the skin bit that equates, needlework or unite by a seam by hand with sewing machine for fur, fritter skin piece is become bulk and nail exhibition, with tackiness agent the stitching trace on skin surface, and physical abuse, retouch cutter, indentures such as pit are floating, chaff plate with the adhesive coated skin, poor plate place, make it infiltrate the chaff plate, poor slab base inside is filled enhancing to the fibre gap of loose poorization, makes base-material with the defective leather leather of repairing, evenly be coated with one deck skin flock binder, replant one deck fine hair, drying is solidified, and can obtain suede garment leather, the shoes and hats luggage leather.Method provided by the invention implements very simple.It is just filled broken hole, scarce piece with needlework and cuticle piece, and the crack is sewed up, and is floating outer scar with tackiness agent, and interior residual filling is strengthened, and with the flocking of existing skin flocking technology, can obtain intact velour.It is compared with common veneer leather, regenerated leather technology, both the raw material skin is not done strict screening, does not also need special production equipment, chemical materials and complicated technology, so general workman just is easy to implement this technology.

[description of drawings]

The present invention has following accompanying drawing:

Fig. 1 sews and mend the front elevation of defective leather for the present invention;

Fig. 2 is the end face structure figure of velour of the present invention along the scytoblastema of A-B line, binder film, matte.

[embodiment]

Below more in conjunction with the accompanying drawings, describe the method that proposes according to the present invention in detail, further describe its implementation detail and working condition.The defective leather that this method relates to comprises: the wound leather of the broken hole 2 that differs in size, the wound leather that there is scarce piece 3 at the edge are arranged in time leather 1 of Xiao Zhang's width of cloth or fritter, the dermatotome, skin edge or the middle wound leather that mechanical tear crack 4 is arranged, the wound leather that machinery scuffing 6 is arranged on the skin surface, the wound leather of retouching cutter hook trace 7 is arranged, the wound leather that the depression pit 8 of chemical corrosion is arranged, there is the residual leather of chaff plate 9 due to the chemical agent damage reticular layer dermatotome inside, has the microbial attack hide fiber to cause residual leather and two, the tri-layer leather of poor plate 10; A kind of manual needlework or sewing machine for fur device of sewing up usefulness arranged, have one, a kind of tackiness agent that skin and flocking are used of mending is arranged, the skin flocking apparatus that has a kind of leather that is generally after the darning to provide matte to use the wood-block 5 of sewing up convex ridge tailor's tack exhibition usefulness.

When implementing this method, needlework or sewing machine for fur device become to be fit to the sheet of cutting cloth to Xiao Zhang's fritter skin 1 piece by hand by flow process, broken hole on the dermatotome 2 is cut equal skin bit squeegees, sew and mend the scarce piece 3 that the skin limit is torn neat, Pi Bian or the middle sealing of tearing 4 are sewed up, with nail the darning convex ridge line on the dermatotome is being stretched behind the wet water on the plank 5, use more than or equal to the tackiness agent of 20000 centipoises the suture after stretching, sealing is floating, floating the mechanical trauma indenture 6 on the surface, cutter hook trace 7 is floating retouching on the surface, floating the various pit indentures 8 on the surface, tackiness agent with 12000～15000 centipoises is applied to chaff plate 9, the surface of poor plate 10, make it be penetrated into dermatotome inside by intended component, fill the poor fibre gap 11 of chaff, chaff plate tensile strength is recovered, the interior fiber of chaff plate is enhanced, repairing on the good defective leather base, evenly be coated with the tackiness agent 12 of one deck 0.5 millimeter～1 mm thick, with existing skin flocking apparatus, for the defective leather that coats tackiness agent is planted one deck fine hair 13, after flocking, residual all vestiges in the wound of on leather, repairing, just covered up effectively, and obtained a kind of defective leather 1 base that has, binder film 12, the suede garment leather that matte 13 three-layered nodes close, cashmere hats and shoes, luggage leather.
