Description
Technical field
The present invention relates to a kind of production technology of leather, the seamless spliced production technology of specifically a kind of leather belongs to skin
Leather and leather and fur products processing technique field.
Background technology
Case and bag product has become the necessity of people's life, in various occasions such as work, commercial affairs, tourisms, various each
The case and bag of sample are also from original single functionalization, and gradually to variation, individualized development, people are to the ornamental, unique of case and bag
The requirement of property also more and more higher.
The existing decorating method on suitcase leather surface, is to use following two modes mostly.A kind of mode is directly in skin
Leather surface is printed or sprayed, in leather surface formation pattern or decorative pattern, for example, CN103132347A discloses a kind of artificial
The surface dye transfer of leather, by dermatine contaminate layer with print, spray or coating method apply with reaction type dye simultaneously
Pattern or decorative pattern are formed simultaneously, and the reaction type dye is determined that layer can be contaminated so as to shape in this through washing and drying fixation program
Into surface printing pattern or decorative pattern, CN102173244B discloses a kind of surface printing process for leather paint layer, by base material
Thermoplasticity priming paint and baking-curing formation prime coat are sprayed, leather dope, baking-curing formation finish paint are then sprayed on prime coat
Layer, the substrate surface of spray-applied primer and finish paint is cleaned totally, then printing-ink pattern, protection is printed on ink logo
Gloss oil, baking-curing ultimately forms printing pattern layer.Another way is by the way of splicing, for example, print will be first passed through in advance
The leather of the processing such as brush, spraying, is cut into fabric of different shapes, these block cutting fabric hot pressing is fitted into splicing
Material, then be molded, or be that the cutting fabric with given shape or special decorative pattern, color etc. that will be cut is direct
The appointed part of case and bag is sutured or be pasted onto, three-dimensional decoration is formed.
By the way of printing or spraying, often pattern or decorative pattern easily drop, and pattern is untrue, to a certain extent easily
Influence is attractive in appearance.Two block leather fabrics are directly carried out laminating splicing by existing splicing production technology, to laminating glue and production work
The requirement of skill is higher, and increase with access times or is influenceed by environmental change, easily causes two block leather fabrics patch
Close side cracking either two block leather fabric shrinkage factors difference and cause decorative layer staggered floor occur, ftracture, come off;And three-dimensional dress
The pattern of decorations can also be influenceed by adhesive linkage or suture site production technology and cause it not to be durable.
The content of the invention
It is an object of the invention to provide a kind of seamless spliced production technology of leather, solve in the prior art, suitcase leather
Printed patterns are untrue, easily drop, and existing leather splicing production process present in splicing layer it is easily peelable, cracking, no
Attractive and durable the problems such as.
Technical scheme is as follows:A kind of seamless spliced production technology of leather, comprises the following steps:
(1)Leather is subjected to Slice by slice cutting, the musculus cutaneus that thickness is 0.5-0.7mm is obtained;
(2)One layer of hot melt adhesive film is covered in the cut surface of musculus cutaneus, first time hot pressing is carried out, 3-6min is cooled down after hot pressing;
(3)Cut using shaped mold on the musculus cutaneus after first time hot pressing and cooling, obtain and carry shaped mold figure
Hollow out musculus cutaneus and hollow out the position part of shape;The spacing of the shaped mold figure outer wheels profile and interior line, Ye Jitu
Shape line roughness is 0.05-0.2mm, when the hollow out position part of acquisition is filled in corresponding hollow out position on hollow out musculus cutaneus, is engraved
Gap is 0.05-0.2mm between the figure in room and corresponding hollow out position part;
(4)Hollow out position part is filled in corresponding hollow out position on hollow out musculus cutaneus, a block leather is separately taken as bottom retainer, tiling
In the hollow out musculus cutaneus bottom for having finished the part filling of hollow out position, second of hot pressing is carried out, 3-6min is cooled down after hot pressing.
It is preferred that cladding thickness be 0.6mm.
Spacing between the figure outer wheels profile and interior line of the shaped mold, namely pattern line rugosity is
0.05-0.2mm, preferably 0.1mm.
Further, the first time hot pressing, the pressure used is 105-130 DEG C of 0.15-0.4par, temperature, for the first time
Hot pressing time 10-20s, second of the hot pressing, the pressure used is 105-130 DEG C of 0.2-0.45par, temperature, second of heat
Pressure time 10-30s.
It is preferred that, the pressure used is 120 DEG C of 0.3par, temperature, first time hot pressing time 15s, second of hot pressing time
20s。
It is preferred that hot pressing after cool time be 5min.
The hot melt adhesive film can be commercially available hot melt adhesive film, preferably TPU membrane.
The cutting of leather of the present invention can be carried out using staking machine, and leather surface layer is retained during cutting;The present invention
Production technology can be applied to leather or the material of other leather-likes.Carrying out step(3)Cutting when, can be same
Carried out on one piece of musculus cutaneus, obtain the hollow out position part with hollow-out fabric identical suits or material;Pre- it can also be first passed through from other
Step(1)、(2)Handle, with being cut on different patterns but thickness and hollow out musculus cutaneus identical musculus cutaneus, obtain and hollow out face
The hollow out position part of skin difference pattern or unlike material, after the hollow out position part filling with different patterns, obtains color rich
Rich splicing figure so that product more personalized, variation.
The present invention is also resided in relative to the beneficial effect of prior art:
(1)Using spacing between figure outer wheels profile and interior line sanction is processed for 0.05-0.2mm shaped mold
Cut, obtain hollow out figure and hollow out position part, it is ensured that the machining accuracy of product;
(2)By hot-forming twice, it is ensured that splicing fastness, in second of hot pressing, it can be achieved to lead to each splice
PUR is crossed to carry out realizing close, seamless laminating between laminating splicing, the plant-on component of each hollow out position, just like completely day
Into one, it is wear-resisting durable;
(3)It is preferred to use TPU membrane, the adhesive thickness with good consistent and uniform so that hollow out position part can be fine after hot pressing
Inlay, it is fixed and be fitted in hollow out position, it is ensured that the uniformity on cladding surface after splicing, while without solvent, environmentally-friendly sanitary,
It is easy to process;
(4)The composed pattern third dimension of acquisition is strong, handsome in appearance, and whole production process step is simple, the operating time is short, effect
Rate is high, safety and environmental protection.
