Description
Technical field
The invention belongs to the leather tanning field, wet ornamenting working method after particularly the positive suede upper leather of a kind of pigskin is tanned.
Background technology
The positive suede upper leather of pigskin (market also claims pig Ba Ge) is to process by the pigskin tannin.On the market, for high-quality pig Ba Ge requirement be: pore is not obvious, and fine hair is fine and closely woven, and is even substantially; Thickness is more than 0.9mm, and general thickness is 1.2-1.5mm; The plentiful softness of leather body, fastness is good; The position difference is little, and deburring is few, the yield of leather height.
The weave construction characteristics that pigskin is main:
(1) grain is coarse, and the pig hair is generally three at surface, and isosceles triangle is arranged.Pore seems thick especially in surface exit flare.Grain nipple projection is obvious, and rill is darker, so the grain that seems is coarse;
(2) the position difference is big, and the position difference shows as greatly: difference in thickness is big, fibrage difference is big and grain difference is big;
(3) difference in thickness: the buttocks of pigskin, belly difference in thickness can change from 4.5mm-1.0mm;
(4) fibrage difference: the stern back fibrous bundle of pigskin is sturdy, is the cruciform braiding, and braiding is tight, and limit belly fibrous bundle is very thin, mostly is the waviness braiding, and braiding is loose, and the neck braiding falls between;
(5) grain difference: the pore thickness of buttocks part of pighide, neck and belly and density, the grain rill depth are all obviously different.Generally, the buttocks grain is flat thin than belly;
Particular tissues constructional feature in view of above-mentioned pigskin, so processing high-quality pig Ba Ge must will keep on improving in technology, formulate process program according to pigskin histological characteristic, the detrimentally affect that reduces that the pigskin grain is coarse, the position difference is big etc. and bring, it is poor that the position of pigskin is dwindled in emphasis, the control buffing degree of depth makes finished leather feel, fine hair even as far as possible.
Pig Ba Ge is because be velour, so prepare workshop section, tanning workshop section before its production is only tanned strictly speaking and back three workshop sections of wet finishing workshop section that tan.Forefathers are for the processing of pig Ba Ge, with focus concentrate on tan before workshop section and tanning workshop section, Special attention will be given to degreasing, depilation liming, softening pickling, in conjunction with the importance of operations such as tanning, and the arrangement of the technical process of workshop section and tanning workshop section before tanning.For the back wet finishing workshop section of tanning, only pay close attention to the several single operations of buffing, dyeing and stuffing to the influence of pig Ba Ge quality, back each inter process of wet finishing workshop section of tanning is lacked a global design, arrangement, often occurs following problem easily so it produces pig Ba Ge:
The buffing degree of depth is big, the hide thickness low LCL, and generally between 0.9-1.2mm, fastness is not enough; Fennel is obvious, and fine hair is different in size, and is inhomogeneous; The inclined to one side plate of leather body is hard; Problems such as the position difference is big, and deburring is serious, and yield of leather is low.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming and defect that prior art exists, and provide a kind of finished product fine hair that processes carefully short, even substantially, there is not obvious pore; The plentiful softness of leather body; Thickness is thicker, and fastness is good; Wet ornamenting working method after the positive suede upper leather of a kind of pigskin of the high-quality pig Ba Ge that yield of leather is higher is tanned.
For achieving the above object, technical scheme of the present invention is to comprise following operation:
A pigskin vamp wet blue leather → water squeezing → shaving (cutting the flesh noodles) → light shaving of secondary (cutting grain) → wet-milling → weigh → return is wet → washing → retanning → washing → neutralization → washing → one time stuffing, filling → wash, go out drum → primary drying → redrying → get damp again → shake soft → dry grind → weigh → backwater → washing → dyeing, secondary stuffing → (dye on the top) → wash, go out drum → drying → soft → (other operations) that get damp again → fall → row's chi, warehouse-in
(1) pigskin vamp wet blue leather: select to be combined tanning with other tanning agents for the leather of processing pig Ba Ge through chrome tanning agent tanning or chrome tanning agent;
(2) water squeezing: conventional operation;
(3) shavings: cut flesh noodles, thickness is with the many 0.1-0.4mm of finished product pig Ba Ge thickness;
(4) the light shaving of secondary: cut grain, cut with complete opening, grain is stretched to cut brokenly be advisable, thickness is not changed to some extent;
(5) wet-milling: the wet blue leather buffing, with the 80-200 emery cloth, demand perfection to open is ground to, and destroys grain;
(6) weigh, return wet, washing, retanning, washing and neutralization, general in and between the pH to 5.0-6.5;
(7) washing;
(8) stuffings, filling: a small amount of stuffing, the fatting agent total amount accounts for the 3-8% of tare weight; The stuffing later stage adds the vegetable tanning agent of tare weight 2-5% and fills; This step stuffing amount by quality ratio;
(9) wash, go out drum;
(10) primary drying: adopt vacuum-drying or paste drying that moisture in the skin is down to 30-40%, by quality ratio, require grain flat thin;
(11) redrying: employing nature extension dries in the air or the drying tunnel extension dries in the air is down to 14-18% with moisture in the skin, by quality ratio;
(12) moisture regain: make tare weight moisture remain on 30% ± 5, by quality ratio;
(13) shake soft: adopt the vibration staking machine to handle, softness is advisable to be fit to buffing;
(14) dry grinding: the crust leather dry grinding, adopt the 150-400 emery cloth, the gradation buffing, emery cloth variation from coarse to fine, first mill flesh noodles, abrasive particle face then is during the abrasive particle face, directly with the direct buffing of big buffing machine, or earlier with little buffing machine edging belly and neck neck, adopt the method for whole buffing of big buffing machine then, require no obvious pore, fine hair is carefully short, even substantially.
(15) weigh, backwater and washing;
(16) dyeing, secondary stuffing, secondary stuffing will consider to deduct that part of stuffing amount that has added in stuffing operation; Total stuffing amount is according to the hide requirement, and fatting agent type and effect have difference, and general pig Ba Ge stuffing total amount is to change between the 5-15%.The secondary stuffing is stuffing amount of total stuffing amount deduction.
(17) drum is dyed (at the dark color leather, light leather can omit), washes and goes out on the top;
(18) drying: adopt vacuum-drying and extension to dry dryly to combine, paste drying dries dry combining with extension, perhaps extension dries dry;
