Abstract
The invention provides a soft leather processing process. The soft leather processing process comprises the following steps: raw material preparing, washing, neutralizing, retanning, dyeing and fat-liquoring, and post-processing. By adopting the processing method provided by the invention, the leather obtains enough softness; and surface fat-liquoring is carried out by use of an unstable fat-liquoring agent, heating, pressurizing, pressing and ironing are carried out after drying, so that the leather is softer.
Description
Technical field
The present invention relates to leather processing field, particularly relate to a kind of moccasin leather processing technique.
Background technology
Leather is the most perishable animal of degeneration obtained by physics, the chemical processes such as depilation and tanning
Skin.Leather is made up of at three dimensions close weave natural protein fibre, and its surface has a kind of special
Grain layer, has natural graining and gloss, comfortable feel.Along with the reach of science, the performance of synthetic leather
Although more and more close to natural leather, but the index of natural leather can not be reached forever.Its reason is skin
The character of leather comes from life sciences.Animal skins is a part for life entity, life sciences deep and profound
The most general physics and chemistry can imitate, and people can synthesize bovine insulin, but definitely can not synthesize public affairs
Cattle, cow and goat.It addition, leatherware the most also has special psychological value, i.e.
Conspicuous and consoling oneself property, this just with have on the ring that ring made of copper makes with gold and be experienced as the same at heart.
Along with the raising of quality of life, people only can be increasing to the demand of leather, and can not move towards decline,
Therefore say that leather industry is that " do not fall day industry " is not more.
Summary of the invention
The present invention provides a kind of moccasin leather processing technique, for realizing the purpose of the present invention, the technical side of the present invention
Case is as follows:
A kind of moccasin removes from office processing technique, and it concretely comprises the following steps:
(1) preparation of raw material: prepare wet oxhide, and peel to thickness be 2-2.2mm；
(2) washing: carrying out washing 5-9min to leather with water, temperature controls at 30-40 DEG C, and washing amount is
300%, add 0.3%Tetrlix SMS afterwards and clean 20-30min；
(3) neutralize: after water washed, add 50% water, be neutralized at 30-35 DEG C；
(4) retanning: the Chromopol SG adding 0.5% carries out leather retanning；
(5) dyeing and fat-liquoring: add stain and leather is dyeed, carry out stuffing technique afterwards；
(6) later stage processes: carry out after stuffing drum, take horse, water squeezing, stretch, be vacuum dried, get damp again,
Flatiron, light pressure, finished product.
Preferably, in step (5), the component of stain is: sodium formate 1.5%, Sellasol NG1.5%,
Kastanie N4%, aniline dyes 2%, sodium bicarbonate 0.3%, Mirosan512 2%, formic acid 1.5%, surplus
For water.
Preferably, it is additionally provided with water-washing step, by the leather after stuffing in the middle of step (5) and step (6)
10min is cleaned at 20 DEG C.
Beneficial effect: the invention provides a kind of moccasin leather processing technique, its step includes: the preparation of raw material,
Washing, neutralization, retanning, dyeing and fat-liquoring, later stage process, and the processing method that the present invention uses makes skin obtain
Enough pliabilitys, then carry out surface stuffing with a kind of non-stable fatting agent, skin is pressed in dried heating pressurization,
Make leather more soft.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with detailed description of the invention, the present invention is expanded on further.
A kind of moccasin removes from office processing technique, and it concretely comprises the following steps:
(1) preparation of raw material: prepare wet oxhide, and peel to thickness be 2-2.2mm；
(2) washing: carrying out washing 5-9min to leather with water, temperature controls at 30-40 DEG C, and washing amount is
300%, add 0.3%Tetrlix SMS afterwards and clean 20-30min；
(3) neutralize: after water washed, add 50% water, be neutralized at 30-35 DEG C；
(4) retanning: the Chromopol SG adding 0.5% carries out leather retanning；
(5) dyeing and fat-liquoring: add stain and leather is dyeed, carry out stuffing technique, stain afterwards
Component be: sodium formate 1.5%, Sellasol NG1.5%, Kastanie N4%, aniline dyes 2%, little
Soda 0.3%, Mirosan512 2%, formic acid 1.5%, surplus are water；
(6) later stage processes: carry out after stuffing drum, take horse, water squeezing, stretch, be vacuum dried, get damp again,
Flatiron, light pressure, finished product.
The invention provides a kind of moccasin leather processing technique, its step includes: the preparation of raw material, washing, in
Process with, retanning, dyeing and fat-liquoring, later stage, the processing method that the present invention uses, make skin obtain enough soft
Softness, then carry out surface stuffing with a kind of non-stable fatting agent, skin is pressed in dried heating pressurization so that skin
Remove from office more soft.
Obviously the present invention implements and is not subject to the restrictions described above, as long as have employed the method structure of the present invention
Think and the improvement of various unsubstantialities that technical scheme is carried out, or the most improved design by the present invention and technology
Scheme directly applies to other occasion, all within protection scope of the present invention.
