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 technique
Luggage product has become the necessity of people's life, various each in the various occasions such as work, commercial affairs, tourism
The luggage of sample is also from original single functionalization, gradually to diversification, individualized development, dicoration, uniqueness of the people to luggage
The requirement of property is also higher and higher.
The existing decorating method on suitcase leather surface is mostly using following two mode.A kind of mode is directly in skin
Leather surface is printed or is sprayed, and forms pattern or decorative pattern in leather surface, for example, CN103132347A disclose it is a kind of artificial
The surface dye transfer of leather, by rtificial leather contaminate layer with print, spray or coating method apply with reaction type dye simultaneously
It is formed simultaneously pattern or decorative pattern, and so that the reaction type dye is determined that layer can be contaminated in this to shape through washing and dry fixation program
At surface printing pattern or decorative pattern, CN102173244B discloses a kind of surface printing process for leather paint layer, by substrate
It sprays thermoplasticity priming paint and baking-curing forms prime coat, leather dope is then sprayed on prime coat, baking-curing forms finishing coat
Layer, the substrate surface of spray-applied primer and finishing coat is clean, ink logo is then printed, protection is printed on ink logo
Gloss oil, baking-curing ultimately form 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, by these block-like cutting fabric hot pressing fittings at splicing
Material, then is formed, or is that the cutting fabric with specific shape or special decorative pattern, color etc. that will cut is direct
The appointed part for suturing or being pasted onto luggage forms three-dimensional decoration.
By the way of printing or spraying, often pattern or decorative pattern are easy to fall, and pattern is untrue, to a certain extent easily
It influences beautiful.Two block leather fabrics are directly carried out fitting splicing by existing splicing production technology, to fitting glue and production work
Skill it is more demanding, and influenced with the increase of access times or by environmental change, two block leather fabrics be easy to cause to paste
It closes side cracking either two block leather fabric shrinking percentages differences and decorative layer is caused staggered floor occur, crack, fall off；And three-dimensional dress
The pattern of decorations also will receive the influence of adhesive layer or suture site production technology and it caused not to be durable.
Summary of the invention
The object of the present invention is to provide a kind of seamless spliced production technology of leather, solve in the prior art, suitcase leather
Printed patterns are untrue, easily fall and existing leather splicing production process present in splicing layer is easily peelable, cracking, no
The problems such as attractive and durable.
Technical scheme is as follows: a kind of seamless spliced production technology of leather includes the following steps:
(1) leather is subjected to Slice by slice cutting, obtains the musculus cutaneus with a thickness of 0.5-0.7mm；
(2) one layer of hot melt adhesive film is covered in the cut surface of musculus cutaneus, carries out first time hot pressing, cooling 3-6min after hot pressing；
(3) it is cut on through first time hot pressing and musculus cutaneus after cooling using shaped mold, obtains and have shape mould
Have the hollow out musculus cutaneus and hollow out position component of figure；The spacing of the shaped mold figure outer wheels profile and interior line,
I.e. pattern line rugosity is 0.05-0.2mm, and the hollow out position component obtained is made to be filled in corresponding hollow out position on hollow out musculus cutaneus
When, gap is 0.05-0.2mm between the figure of hollow out position and corresponding hollow out position component；
(4) hollow out position component is filled in corresponding hollow out position on hollow out musculus cutaneus, separately takes a block leather as bottom retainer,
It is laid in hollow out position component filled hollow out musculus cutaneus bottom, carries out second of hot pressing, cooling 3-6min after hot pressing.
Preferred cladding is with a thickness of 0.6mm.
Spacing namely pattern line rugosity are between the figure outer wheels profile and interior line of the shaped mold
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
Press time 10-30s.
Preferably, the pressure used is 120 DEG C of 0.3par, temperature, first time hot pressing time 15s, second of hot pressing time
20s。
Cooling time after preferred hot pressing is 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 when cutting；The present invention
Production technology can be applied to the material of leather or other similar leather.It, can be same when carrying out the cutting of step (3)
It is carried out on one piece of musculus cutaneus, obtains the hollow out position component with hollow-out fabric identical suits or material；It pre- can also be first passed through from other
Step (1), (2) are handled, with being cut on different patterns but thickness and the identical musculus cutaneus of hollow out musculus cutaneus, are obtained and hollow out face
It is rich to obtain color after the hollow out position component filling with different patterns for the hollow out position component of skin difference pattern or unlike material
Rich splicing figure, so that product more personalized, diversification.
The beneficial effect of the present invention compared with the existing technology also resides in:
(1) added using the shaped mold that spacing between figure outer wheels profile and interior line is 0.05-0.2mm
Work is cut, and is obtained hollow out figure and hollow out position component, be ensure that the machining accuracy of product；
(2) process is hot-forming twice, ensure that splicing fastness, in second of hot pressing, it can be achieved that by each splicing
Part carries out fitting splicing by hot melt adhesive, realizes close, seamless fitting between the plant-on component of each hollow out position, just like it is muddy
Right day at one, it is wear-resisting durable；
(3) TPU membrane is preferably used, the adhesive thickness with good consistent and uniform, so that hollow out position component can after hot pressing
Hollow out position is inlayed, fixed and be fitted in well, guarantees the consistency on cladding surface after splicing, while being free of solvent, environmental protection
Health, it is easy to process；
(4) the composed pattern three-dimensional sense obtained is strong, handsome in appearance, and entire production process step is simple, the operating time
It is short, high-efficient, safety and environmental protection.
Detailed description of the invention
Fig. 1 is after cutting, and there are the hollow out musculus cutaneus schematic diagrames of hollow out figure；Fig. 2 is from the portion that musculus cutaneus is cut
Divide hollow out position block diagram；Fig. 3 is hollow out position component to be stuffed entirely with into hollow out musculus cutaneus to corresponding hollow out position, and place one
Open the schematic diagram of bottom retainer.
