Abstract
The invention provides a leather and a leather product, and a processing method thereof. The processing method comprises the following treatments on a defatted and depilated raw hide material: liming, deashing pickling, tanning, retanning and bottom dyeing, toggling drying, finishing, gloss oil spraying, ironing and milling. The finishing process is as below: dropwise adding liquid wax on back of a dry hide blank subjected to toggling drying, and infiltrating the liquid wax to the front of the dry hide blank to show liquid wax stain; rubbing the front of the dry hide blank with the liquid wax for 1-5 times, drying, and continuing to rub the liquid wax for 1-3 times; and spraying gloss oil on the hide blank applied with a cracking liquid and ironing the hide blank at the temperature 90-115DEG C for 3-15 s. The invention also provides the leather processed by the above method. Through improving the finishing process, the invention endows the appearance of the leather with rich color changes and varied texture, so as to produce different visual and sensory effects.
Description
Technical field
The present invention relates to a kind of leather and leatherware and working method thereof, belong to leather processing technical field.
Background technology
The development of leather industry and human lives and national economy is closely bound up, is the mainstay industry of light industry.At present, leatherware on market has had good, the fashionable and coloury feature of use properties, but be subject to the restriction of complete processing, leatherware is common " uniform " on style and tone, for example, can there is not notable difference in for example, outward appearance and feel with the homochromy naughty goods of style (case and bag), human consumer is in use difficult to embody individual character, even there will be the embarrassment of " collision ", in this case, even very high-grade goods, its quality and effect also can be had a greatly reduced quality.Along with improving constantly of consumption idea, people also improve the requirement of leather thereupon, human consumer of today not only payes attention to leather quality, and the abundant variation that brings of the outward appearance vision of more pursuing leatherware and the diversity effect of leather skin texture texture, thereby reach embodiment individual character, lead the object of trend.Therefore, personalization that how can more perfect embodiment leatherware, enriches leatherware and brings people's visual effect, to meet human consumer's higher demand, is the unremitting pursuit of people and yearning always.
Summary of the invention
Technical problem underlying solved by the invention is to provide a kind of working method of leather, by the improvement to covering with paint technique, make the outward appearance of leather there is abundant chromatic aberration and various skin texture texture, even if utilize same skin base to process the goods of identical style, also can produce different visions and sensory effects.
The present invention also provides a kind of leather and leatherware that utilizes aforesaid method processing.
The invention provides a kind of leather processing method capable, comprise the raw stock through degreasing depilation is handled as follows: liming, deliming pickling, tanning, retanning dye the end, toggling oven dry, covering with paint, blast finishing ink, it is soft to press, fall, wherein, described covering with paint technique is as follows:
Drip oily wax liquid at the reverse side of dry hide base of drying through toggling, and it is positive and manifest fuel-displaced wax liquid stain trace to make dripped oily wax liquid infiltrate into dry hide base;
Utilize oily wax liquid to carry out obliterating 1-5 time in dry hide base front, after it is dry, continue obliterating be full of cracks liquid 1-3 time;
Described leather processing method capable has also comprised that to obliterating the skin base of be full of cracks liquid carries out after blast finishing ink hot pressure 3-15 second at temperature 90-115 ℃.
The present invention is in covering with paint technique, and the raw material composition of used oil wax liquid can be (% by weight): oily 5-20%, wax 45-70%, permeate agent 5-15% and water 20-40%.
The present invention is in covering with paint technique, and the raw material composition of be full of cracks liquid used can be (% by weight): cracking resin for synthesizing 10-30%, casein 30-50%, permeate agent 2-8%, light agent 3-7% and water 20-40%.
The present invention is in covering with paint technique, and in this oil wax liquid, described grease separation, from vegetables oil or animal oil, is known in this field and conventional oil, and those skilled in the art can suitably select as required.
The present invention is in covering with paint technique, and in this oil wax liquid, described wax for example can be, petroleum wax and the derivatives such as paraffin, Microcrystalline Wax, Vaseline; The polyolefin-wax such as polyethylene wax, Poly Propylene Wax and derivative; The synthetic waxs such as Fischer-Tropsch wax; The natural series waxes such as rice wax, carnauba wax; Ester is that wax, department of botany's wax, animal are wax, SOLID ORGANIC silicon wax, montanin wax etc., is known in this field and conventional wax.
The present invention is in covering with paint technique, in this oil wax liquid, the effective constituent of described permeate agent is selected from alkylphenol polyoxyethylene, aliphatic alcohol polyethenoxy alcohol, aliphatic poly ammoniacum emulsion or aerosol-OT salt etc., be known in this field and conventional permeate agent, those skilled in the art can select as required.
The present invention is in covering with paint technique, in this be full of cracks liquid, the effective constituent of described permeate agent is selected from alkylphenol polyoxyethylene, aliphatic alcohol polyethenoxy alcohol, aliphatic poly ammoniacum emulsion or aerosol-OT salt etc., be known in this field and conventional permeate agent, those skilled in the art can select as required.
The present invention is in covering with paint technique, and in this be full of cracks liquid, described light agent is known to the skilled person and conventional leather polish, can select as required.
Method of the present invention is particularly useful for processing the finer and close rawhide of texture, such as various ox-hides, sheepskin, pigskin etc.
The present invention also provides a kind of leather, and this leather can be that the method for recording according to the present invention obtains.In the present invention, utilize the leather of this working method production because of the variation of its chromatic aberration and cortex skin texture, be also referred to as " month covering ".
Adopt " month covering " provided by the invention can the various case and bag of processing and fabricating, furniture or article overcoat (such as cell-phone cover, IPAD protective sleeve etc.), the grain effect on surface, makes it in numerous leathercrafts, can demonstrate noble quality, cultured and unusual.
Compared with prior art, technical scheme of the present invention has following beneficial effect:
The present invention has changed in conventional leather working method and has covered with paint, lacquer, colour wash, etc. technique,, traditional covering with paint processing requirement is at the dry hide base front face surface spraying daub of drying through toggling and wiping or waxing wet goods, require evenly to embrocate as much as possible, the final consistence of monoblock skin base on outward appearance and tone of pursuing, utilize the goods of such skin base processing also just inevitable uniform, and lacking individuality difference; And the present invention is dripped oiling wax liquid at the reverse side of skin base, again at positive obliterating oil wax liquid and be full of cracks liquid, and drip and be coated with and the ununiformity of obliterating process by control, thereby process and there is the abundant and various leather of skin texture texture of aberration, even if utilizing the goods that such leather is processed is same style, same to tone, for example can process various case and bag, can not there is duplicate appearance effect yet, user no longer worries the embarrassment that " collision " brings, more be beneficial to and meet that human consumer looks for novelty, the individual sexual demand of changes persuing, be also beneficial to the quality that promotes leathercraft.
