Abstract
The invention provides a method for forming pebble-grain surface of cowhide leather. The method comprises the following steps: 1) placing blue leather in a drum; adding water, oxalic acid and sulfated ester compounds; rotating the drum; and carrying out water discharge, water washing and water exchange; 2) adding water and aliphatic series polyaldehyde; rotating the drum; neutralizing with alkali; adding crylic acid and grease; rotating the drum; and carrying out water discharge, water washing and water exchange; 3) adding water, crylic acid, a synthetic tanning agent, dispersed tannin, a mimosa extract, a quebracho extract and a dye and rotating the drum; 4) dying through the core with the dye, then adding melamine, dicyandiamide, the mimosa extract, the quebracho extract, grease and a pebble forming agent; rotating the drum; and solidifying acid and exchanging water; and 5) adding water, crylic acid and grease and rotating the drum; solidifying acid; carrying out water discharge, water washing and water exchange; 6) adding water and oil-wax fatliquor, and 7) carrying out dry finishing. By the method, a pebble effect can be naturally exerted on the grain surface of the leather and the potential added value of the leather is expanded.
Description
Technical field
The present invention relates to a kind of formation method of ox-hide bubble grain.
Background technology
The grain that existing method for leather-making produced, or be the wholegrain face, and be planar, it is little that effect is hindered in screening; Be embossing, in order to hide wound, and change the natural effect of grain side of leather, lack the natural beauty of leather; Be through buffing, remove epidermal area, letting the human consumer can not distinguish is corium, reduces the class of leatherware, thereby reduces economic worth and result of use.
The content of invention
The object of the present invention is to provide a kind of formation method of ox-hide bubble grain, present method can form bubble effect, neither buffing naturally on grain side of leather; Also not embossing; Keep the wholegrain face, but bubble hides permanent disability again, and beautiful spatial grain is arranged again; With the use value and the aesthetic effect of 3-D effect raising leather, enlarge the potential added value of leather greatly.
For achieving the above object, technical scheme of the present invention is:
A kind of formation method of ox-hide bubble grain comprises the steps:
1, a kind of formation method of ox-hide bubble grain is characterized in that comprising the steps:
1) blue skin is placed in the rotary drum, add 35 ℃ water, oxalic acid, sulfonated ester compound (model: PF; Production firm: German bright mirror company), rotated 120 minutes, draining then, wash, change water;
2) add 30 ℃ water, aliphatics polymerization aldehyde rotated 15-30 minute, again with in the alkali with 40 minutes, adding vinylformic acid, grease rotation 30 minutes, draining then, wash, change water;
3) add 25 ℃ water, add vinylformic acid, synthetic tanning agent, dispersion tannin, wattle extract, quebracho extract, dyestuff and rotated 60 minutes;
4) pass through the heart through dyeing after, add trimeric cyanamide, Dyhard RU 100, wattle extract, quebracho extract, grease and bubble and form agent and rotated 60 minutes; Water is changed in the solid acid of stuffing then;
5) add 45 ℃ water, add vinylformic acid, grease rotated 50 minutes, water is washed, changed to the solid acid of stuffing then, at draining;
6) add 65 ℃ water, add oily wax fatting agent, rotated 30 minutes;
7) change water, cold water washing goes out drum, takes horse, and hold over night stretches, vacuum, extension dries in the air, drying, fall soft, toggling.
The ratio of the adding weight part of described step 1) medium blue skin, water, oxalic acid and sulfonated ester compound is: 100:150:0.5:0.7.
Described step 2) add-on of water is 1 times of blue skin weight part in; The add-on of aliphatics polymerization aldehyde is 2 times of (model MS-1 production firms: Hong Linhua company) of blue skin weight part; Acrylic acid add-on is 2% of a blue skin weight part; The grease add-on is a 1% (model: FA-78: production firm: Hong Linhua company) of blue skin weight part; Described alkali adopts NaHCO
3, add-on is 1.2% of a blue skin weight part.
The add-on of water is 1 times of blue skin weight part in the described step 3); Acrylic acid add-on is 2% of a blue skin weight part; The add-on of synthetic tanning agent is a 3% (model: JHL of blue skin weight part; Production firm: Zhejiang is contained and is converged); Disperseing the add-on of tannin is 0.5% (model: JM of blue skin weight part; Production firm: Zhejiang is contained and is converged); The add-on of wattle extract is 6% (model SRT of blue skin weight part; Production firm: SETA company); The add-on of quebracho extract is a 4% (model: ATO of blue skin weight part; Production firm: SETA company); The add-on of dyestuff is a 3% (model: WP of blue skin weight part; Production firm: that God in charge of the Earth department).
The add-on of trimeric cyanamide is a 3% (model: RT-DX of blue skin weight part in the described step 4); Hong Linhua company), the add-on of Dyhard RU 100 is 1.5% (model: RT-DA of blue skin weight part production firm:; Hong Linhua company), the add-on of wattle extract is 6% (model: SRT of blue skin weight part production firm:; SETA company), the add-on of quebracho extract is 4% (model: ATO of blue skin weight part production firm:; SETA company), greasy add-on is 1.5% (model: AK of blue skin weight part production firm:; Production firm: Smit company); The add-on that bubble forms agent is a 5% (model: RT-NP of blue skin weight part; Production firm: Hong Linhua company); The add-on of fat is a 2% (model: Smit company of PolyolAK production firm) of blue skin weight part.
The add-on of water is 1 times of blue skin weight part in the described step 5); Acrylic acid add-on is 2.5% of a blue skin weight part; The grease add-on is 2.5% (model 2.5NT of blue skin weight part; Production firm: the thick company of power); The add-on of fat is 2% (model FA-78, a production firm: Hong Linhua company) of blue skin weight part.
The add-on of water is 1 times of blue skin weight part in the described step 6); The add-on of oil wax fatting agent is that (wherein to adopt model be SSW to 3/4ths amount for the 3-5% of blue skin weight part
#All the other amounts of 1/4th adopt model EXP; Production firm: be U.S. SALEM company).
The invention has the beneficial effects as follows: the present invention adds sulfonated ester compound at the blue skin retanning initial stage, is intended to handle blue skin to such an extent that color and luster is beautiful, and uniformity significantly stretches the neck line, opens the belly coarse groove, thereby improves yield of leather.Carry out the aldehyde retanning then, obtain bulky hand, the careful grain of consolidation.Neutralization is then created suitable infiltration and combining environmental for back filling, stuffing, bubble form.Adding vinylformic acid, trimeric cyanamide, Dyhard RU 100, synthetic tanning agent, is poor in order to improve the position, improves the leather fullness ratio.Adding wattle extract, quebracho extract are in order to let leather obtain good flexibility, to be come out boldly, the leather of good springiness (low elongation).The inventive method retanning process does not adopt the chromium retanning, reduces the chromium constituent content greatly, is beneficial to environmental protection, reduces environmental protection treatment difficulty and cost, and improves the environmental protection concept of leather relatively, and it is relieved that the guide consumption person uses.Core of the present invention is to add bubble and forms agent NP, and it is a kind of displaced type synthetic tanning agent, gives leather careful grain, helps vegetable tanning agent rapid permeability and dispersion, obtains splendid fullness ratio and soft hand feeling, obtains careful, warping strength grain simultaneously.Key is the effect through it, make grain epidermis rule to heaving in the air, form the pearl face effect of stereoscopic three-dimensional, look exactly like many beautiful bubble lifes on grain side of leather.So product of the present invention is the bubble ox.After the said process, add grease and oily wax fatting agent, vouchsafe more oily oil sense of leather, but leather does not seem dry because added so much tannin extract with other tanning agent, and increase leather soft effect and stronger tear-resistant and anti-blasting effect.
