Description

Colour patterned leather and production method thereof

The invention relates to batik, tie dyeing new technology and produce, have the leather and the production method thereof of chromatic pattern pattern.

Traditional technology of stamp on cloth is not suitable for leather, and on leather, carry out the method for colour printing and dyeing, although people have done many explorations, and effect is all undesirable, Here it is can only see the leather and fur products of solid color for a long time on market, and seldom sees the reason of the especially colored flower musculus cutaneus of colored musculus cutaneus leather leather goods.

The purpose of this invention is to provide a kind of colour patterned leather and production method thereof, can produce clothing leather and other surface leather at an easy rate with this method with chromatic pattern art pattern, the clothes made from this leather, shoes and hats, case and bag, ornament etc., can increase aesthetic feeling, thereby beautify people's life.

The batik that the inventor is traditional with China, knot dyeing method are diverted from one use to another in leather after improving, and have obtained success.

Batik, tie dyeing are a kind of traditional handicrafts that dyes on cloth, and its technical essential is: batik is to describe on cloth or printed patterns (being called encaustic painting) with the wax liquid of fusing; Tie dyeing is to tie up cloth (being called embroider) with rope, band by the pattern of design; Then above-mentioned cloth is dropped into the dyeing (be called and dye primary colours) of heating in the dye liquor; Dye and cloth is taken out dry leveling after good, have the resist printing effect, thereby do not dye primary colours or dye lightlyer, thereby form the pattern of various uniquenesses owing to be coated with the place of waxing liquid or tying.In China, generally this product is on sale throughout the domestic and international market as workmanship or local native article, spend cloth in vain as the orchid of Anshun, Guizhou batik factory production and promptly belong to this type of.

The inventor has analyzed above-mentioned process, because its pattern produces with the resist printing method, if this method is diverted from one use to another in leather, institute's impression case decorative pattern that can not adopt the general method of printing and dyeing and produce, protrude from the bad feel of leather surface, simultaneously the inventor also sees, the pattern that produces with the method is that same shade changes and produces, and color effect can't occur.This inventor is further done following trial again also obtained success.

The feature of this method is to wait to dye on the leather surface, method with coloring grounding obtains colored, promptly use the shades of colour dyestuff in advance, pattern by design, adopt picture, spray, brush, method such as be coated with is made colour with leather surface, and then with the fusing wax liquid or other resist agent on this leather surface, manufacture pattern (encaustic painting), and/or with restricting, band is tied up resist printing (embroider), this leather is submerged in the dark dye solution, heat up and the maintenance certain hour, dye (dying primary colours), take out after cooling, clean, softening, fixation, postprocessing working procedures such as typing leveling can produce had both had traditional wax, artistic characteristic of bandhnu has the leather of the various color artistic patterns of colored impression again.Select leather coloring technology commonly used to dye.

Leather of Sheng Chaning and goods thereof in this way, not only bright and colourful, both artistic and practical, have China traditional wax, artistic characteristic of bandhnu, and COLOR FASTNESS height, soft level and smooth, production equipment is simple, and is cheap, help dominating the market, for society provides a kind of new colour patterned leather and production method thereof.

Among the embodiment of this production method such as Fig. 1, the figure

Operation 1 is for giving treatment process, and be mainly to improve Color and establish, as use water-soluble dye, owing to often have grease on the leather, easy dyeing not, the processing of methods such as available soap boiling.

Operation 2 is the coloring grounding operation, this operation is to give on the leathering of processing in process, requirement according to artistic design, use versicolor dyestuff, with specific method such as drawing, spray, brush, be coated with, impose on leather, form colored patch decorative pattern, pay special attention to the transition and the linking of different colours patch decorative pattern intersection, make it harmony.

The another kind of method that realizes this operation is that dyestuff is imposed on the medium, this medium is contacted with leather and makes leather catch background color.

Operation 3 is encaustic painting or embroider operation, can only use encaustic painting on same block leather, also can only use embroider, also can be simultaneously with above-mentioned two kinds of methods.Encaustic painting is to draw or printed patterns on the leather surface of first-class background color with wax liquid or other resist agent of fusing, and this method is suitable for manufacturing well-regulated pattern; Embroider is to tie up above-mentioned leather or together tie up with medium with rope, band.On same leather surface, can prick one or more wisps, tie up the different resist printing effect of the different generations of tightness, be suitable for manufacturing irregular decorative pattern.The something in common of encaustic painting and embroider is it all is a kind of resist printing processing method, makes it after dying primary colours through operation 4, handles the background color that kept owing to above-mentioned resist printing and forms contrast with darker primary colours and present various patterns.Before operation 4,, also can on product, form abundant random little line and be called the ice line if leather is pieced together stranding, folding.

Operation 4 is for dying primary colours, and the darker color of general employing if use water-soluble dye, then needs and will drop into through the leather of operation 3 in the container, and the adding primary colours aqueous solution is to the submergence leather, and heating up also keeps certain hour to get final product.Temperature generally is no more than 95 ℃ in this operation, in order to avoid influence the leather performance.

Operation 5 is for cooling, cleaning, the leather that will dye primary colours removes tie string, band cools off and the flush away loose colour.

Operation 6 is post processing, and this operation is primarily aimed at former operation and establishes, and can comprise dewax and fixation treatment, the softening all or part of contents such as processing, dried of handling, finalize the design.Dewax is that the wax liquid that solidifies is removed; Fixation is in order to increase COLOR FASTNESS, and softening is to softening processing through leather that may hardening after the dyeing, making it to become softness, setting is that the leather that has wrinkled is flattened, recover smooth bright and clean, drying is to make the moisture of leather reach the requirement of regulation, in order to warehouse-in or shipping.

Claims (2)
