Abstract
The invention relates to a manufacturing method for improving the heat-resistant performance of leatherboard in the wool sheepskin industry, in particular to a method for manufacturing high temperature-resistant wool sheepskin for shoes and boots. In the high temperature-resistant wool sheepskin, the leatherboard can resist high temperature of 150 DEG C. The method comprises the steps of: preparing blank skin before weighing and processing the blank skin after degreasing; and the method is characterized in that: a process between the weighing process and the degreasing process comprises the steps of retanning, standing, pickling and rinsing, wherein in the retanning step, a fatliquor GLH which is diluted by adding hot water, diluted formic acid, chromium powder, Bayer zirconium ZB33 and sodium bicarbonate are added to extract alkali. In the key technology, a method for combining a chrome tanning agent and a zirconium tanning agent is adopted in the retanning process; and the leatherboard of products produced under the condition that the using amount of the chrome tanning agent and the zirconium tanning agent is adjusted to a reasonable ratio meets the requirement of resisting temperature of 150 DEG C completely, fibers of the leatherboard are compact, and the dyed leatherboard is bright and strong in colors. The products are suitable for fields of manufacturing the shoes and boots, the high temperature-resistant wool sheepskin and the like.
Description
Technical fieldThe present invention relates to the making that shearling industry dermatotome resistance toheat improves, especially relate to the high temperature resistant footwear boots shearling making method that the dermatotome heatproof will reach 150 ℃.
Background technologyCompany obtains client's information at the beginning of 2010, and a kind of product that a domestic foreign trade corporation makes is badly in need of wanting a kind of heatproof to reach 150 ℃ high temperature resistant footwear boots shearling.All about 95 ℃, the shearling that can reach anti-150 ℃ of high-temperatures still belongs to blank at home, outward shearling product heatproof degree generally speaking.
Retanning occupies critical role in fur industry; It is that the good skin base of tanning is carried out another tanning, can replenish the deficiency of just tanning, and improves the stability of skin base chemically-resistant effect; Help follow-up housekeeping operation; Improve use properties, increase value-added content of product to greatest extent, be suitable for the needs of various uses.
At present, chrome tanning agent retanning, aldehyde tanning agent retanning, aluminum tanning agent retanning or synthetic tanning agent, vegetable tanning agent, resene tanning agent retanning several different methods are generally taked in the fur retanning, and effect that different retanning methods reaches and excellent, shortcoming thereof have nothing in common with each other.The advantage of chrome tanning agent retanning is to improve the shrinkage temperature of dermatotome, and the stability of the fullness of increase dermatotome, elasticity, flexibility, chemical-resistant reagent and anionic dyestuff are to the colourability of dermatotome; Along with the fur industrial expansion, requirement higher, that upgrade has been proposed for fur and goods thereof both at home and abroad, impel fur manufacturing technology constantly to be able to improve.How to improve anti-shrinkage temperature, reach customer requirement, become the problem that fur retanning operation presses for solution.
Product development for the shearling of accomplishing anti-150 ℃ of high-temperatures; My engineering technical personnel of company mainly from screening material, change test such as processing condition and start with, combine retanning with chromium with different retanning materials, through contrasting to the simultaneous test of several kinds of retanning materials with to the test of many times of retanning method; The retanning technology that development makes new advances; After the appearance piece is manufactured experimently out, under 150 ° of C conditions, test, do not shrink in 2 minutes; The color of footwear boots skin through draw a design, setting-out reaches customer requirement, makes product dermatotome heatproof and the hair color produced reach customer requirement.
Summary of the inventionThe object of the present invention is to provide a kind of high temperature resistant footwear boots shearling making method, the shearling that this method is made, heatproof can reach 150 ℃.
The present invention realizes that the technical scheme that above-mentioned purpose takes is following: a kind of high temperature resistant footwear boots shearling making method; Comprise base skin before weighing prepare with degreasing after the base skin handle, it is characterized in that weighing and degreasing between process flow be: retanning, leave standstill, pickling, rinsing; Concrete technical matters step is following:
Steps A, base skin are prepared
Undertaken by existing following common process step: footwear boots base skin, cropping, swabbing, boiling hot hair, cropping, secondary swabbing are scalded hair, carding, cropping, brush formic acid liquid, scald hair, cropping, are checked, weigh, and said weighing is accurately to weigh 132 kg/ grooves as following operation materials foundation;
