Description

High temperature resistant footwear boots shearling making method
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 to 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, improve the stability of skin base chemically-resistant effect, be conducive to follow-up housekeeping operation, improve use properties, increase to greatest extent value-added content of product, the needs of applicable 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, the effect that different retanning methods reaches and excellent, shortcoming is different.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, higher, Secretary has more been proposed for fur and goods thereof both at home and abroad, impel fur manufacturing technique constantly to be improved.How to improve anti-shrinkage temperature, reach customer requirement, become fur retanning procedures problem in the urgent need to address.
Product development for the shearling of finishing anti-150 ℃ of high-temperatures, I engineering technical personnel of company mainly start with from tests such as screening material, change processing condition, be combined retanning with chromium with different Retanning Materials, by to the simultaneous test of several Retanning Materials with to the test of many times contrast of retanning method, the retanning process that development makes new advances, after the sample piece is manufactured experimently out, under 150 ° of C conditions, test, do not shrink in 2 minutes; The color of footwear boots skin by 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 the method is made, heatproof can reach 150 ℃.
The present invention realizes that the technical scheme that above-mentioned purpose takes is as follows: a kind of high temperature resistant footwear boots shearling making method, comprise base skin before weighing prepare with degreasing after the base skin process, it is characterized in that weighing and degreasing between process flow be: retanning, leave standstill, pickling, rinsing; Concrete technical matters step is as follows:
