Abstract
The invention provides a manufacturing method for chromium-free aldehyde-free tanned pigskin shoe lining leather. The method comprises the following steps: placing bare pigskin in a rotary drum and then adding industrial salt, sodium bicarbonate, peregal and disodium ethylenediaminetetraacetate; then adding a zirconium tanning agent, sodium bicarbonate and an aluminum tanning agent into the rotary drum, heating an obtained mixture to a temperature of 40 DEG C, allowing the rotary drum to rotate for 180 min, stopping the rotary drum and standing the rotary drum overnight; in the next day, taking the pigskin out from the rotary drum, carrying out washing, adding the washed pigskin into the rotary drum, then adding water, neutralization tannin and sodium bicarbonate into the rotary drum again and draining off water; adding water, Tara powder, a penetrating agent, sulfited fish oil, sulfited rape oil and formic acid into the drained rotary drum, taking the pigskin out from the rotary drum and stacking and standing the pigskin; and carrying out toggling, milling, toggling, trimming, ironing, grading and measuring according to a conventional process so as to obtain the chromium-free aldehyde-free tanned pigskin shoe lining leather. According to the invention, through addition of disodium ethylenediaminetetraacetate as a masking agent, a pH value is reasonably adjusted, process balance that the surface of the zirconium tanning agent is not excessively tanned and the aluminum tanning agent is not easily eluted is achieved, and manufacturing of the chromium-free aldehyde-free tanned pigskin shoe lining leather is made possible.
Description
Technical field
The present invention relates to a kind of manufacture method of lining leather of pigskin shoes, be specifically related to the manufacture method of a kind of Chrome-free without aldehyde tannage lining leather of pigskin shoes.
Background technology
Lining leather of pigskin shoes is an important kind of leather, and wherein the content of sexavalent chrome and Cr (VI) and free formaldehyde is an important green technology index of lining leather of pigskin shoes goods, directly determines the quality of lining leather of pigskin shoes.If containing Cr (VI) and free formaldehyde in leather goods, injury can be produced to human body.After entering 2010; European Union's most countries specifies in succession, footwear leather is after heat aging, and the content through test Cr (VI) is less than 3mg/kg, and free formaldehyde is less than 75mg/kg leather, in children's goods and toy product, Cr (VI) must not detect, and free formaldehyde is less than 25mg/kg.
The existing manufacture method of lining leather of pigskin shoes is:
1) by the control to the stages operating method such as process, tanning, neutralization, dyeing, retanning, oiling, arrangement, storage of pigskin raw material skin, make the content of the Cr (VI) in the leather goods produced lower than 2.5mg/kg.The method adopts conventional chrome tanning process, controls again the quantum of output of Cr in finished product (VI), relative environmental protection.But due in finished product containing a large amount of Cr (III), therefore when being processed into finished shoe, when human consumer wears the shoes that this shoe lining leather makes, in burn-in test process, under heating and effect of sunlight, all can produce Cr (VI), the health of harm human consumer.(king Chu. the manufacture craft of lining leather of pigskin shoes: China, CN200710070363 [P] .2008-01-09.)
2) adopt organophosphorated salt chrome-free tanning agent, produce environmental protection without chrome tanning lining leather of pigskin shoes by softening, pickling, main tanning, rewetting, oxidation, neutralization, retanning, full gear.There is no chrome tanning agent in the method course of processing, Cr (VI) can not be produced, relative environmental protection.But owing to containing organophosphorus tanning agent in finished product, therefore after being processed into finished shoe, in considerable time, even whole shoes are scrapped completely from being processed into, and under heating and effect of sunlight, all constantly can produce free formaldehyde, the health of harm human consumer.(Wang Dezhen. a kind of manufacture method of chromium-free tanning environment protection pigskin shoes: China, CN200910036633 [P] .2009-06-24.)
Summary of the invention
The object of the invention is to provide a kind of without chrome tanning, does not contain formaldehyde, environmental protection, to the Chrome-free of the people's friendly manufacture method without aldehyde tannage lining leather of pigskin shoes.
For achieving the above object, the technical solution used in the present invention is:
1) disacidify: the naked pigskin after getting 100 parts of picklings by mass fraction and the normal-temperature water of 100 parts add in rotary drum, and then in rotary drum, add 8-15 part Industrial Salt rotate 30 minutes, add 0.2-0.8 part sodium bicarbonate, 0.1-0.3 part peregal and 0.1-0.3 part disodium ethylene diamine tetraacetate rotate 45 minutes;
2) main tanning: add 1-3 part zirconium tanning agent and rotate 120-180 minute in rotary drum, the sodium bicarbonate adding 0.1-0.5 part rotates 30 minutes, add 1-3 part aluminum tanning agent and rotate 90 minutes, add 0.2-0.8 part sodium bicarbonate again and rotate 30 minutes, the pH value of regulator solution is be warmed up to 40 DEG C after 3.8 to turn 180 minutes, stops drum and spends the night;
3) neutralize: next day, go out drum, washing, the pigskin after washing is joined in rotary drum, then to add in rotary drum in 200 parts of normal-temperature water and 1-3 part and tannin rotates 30 minutes, add 0.2-0.5 part sodium bicarbonate and rotate 30 minutes, add 0.6-1 part sodium-acetate and rotate draining after 30 minutes;
4) retanning is refueled: the normal-temperature water adding 200 parts in the rotary drum after draining, 3-6 part tower draws powder and 0.2 part of permeate agent fatty alcohol-polyoxyethylene ether to rotate 60 minutes, add 1-3 part sulfited fish oil and 1-3 part sulfiting rape seed oil rotates 30 minutes, be warming up to 55 DEG C again to rotate 90 minutes, add 0.5-1 part formic acid and rotate 30 minutes, add formic acid 0.5-1 part again and rotate 30 minutes, wash out drum take horse leave standstill;
5) technique is carried out toggling, is fallen soft, toggling routinely, namely deburring, pressing, classification, gage obtain Chrome-free without aldehyde tannage lining leather of pigskin shoes.
Because zirconium tanning agent easily collapses face, surface is crossed and is tanned, aluminum tanning agent is not water-fastness, easy wash-out out, the present invention is masking agent by adding disodium ethylene diamine tetraacetate, Reasonable adjustment pH, reaches zirconium tanning agent surface and only to tan and aluminum tanning agent is not easy wash-out technological balance out, make to create possibility without aldehyde without chrome tanning lining leather of pigskin shoes.Tanned as main by the cheap aluminum tanning agent without potential murder by poisoning and a small amount of zirconium tanning agent simultaneously, draw powder as retanning by natural tower, thoroughly achieve the manufacture of lining leather of pigskin shoes that is real, that can wear next to the skin.Moreover present method operation is basic technological operation, is applicable to tannery's commercial application.
