Abstract
The present invention discloses a method for producing washable reverse raised leather. It is characterized by making scytoblastema successively undergo the procedures of rehydration, retanning, washing by using water, neutralizing, washing by using water, dyeing, fattening, color-fixing and washing by using water according to the conventional mode.
Description
Technical field
The present invention relates to a kind of treatment process of suede leather, especially a kind of manufacture method of washable suede.
Background technology
Suede is a skin of the skin surface being worn into the villous effect, and the product permeability made from suede is good, and outward appearance is elegant and graceful, and is wear-resistant, but its deficiency is easily dirty and difficult maintenance.Particularly under the bad situation of environment, matte is easily inhaled people's dust, meets water and will make the fine hair lodging again, and the distortion of fading owing to can not wash, is maintained and clean pretty troublesome.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of washable suede, the suede of making by this method can directly clean in water and be colour-fast, indeformable.
Technical scheme of the present invention is such: a kind of manufacture method of washable suede, be achieved by the following scheme: prepare the suede embryo, scytoblastema is carried out backwater, retanning, washing, neutralization, washing, dyeing, stuffing, solid acid and washing step in the usual way successively; And between above-mentioned dyeing process and stuffing operation, carry out fixation operation and washing step successively, the fixation operation is to carry out in the mixture of the cationic fixing agent of the derivative of aliphatic amide, and requiring pH value is 3.8-4.0, by this fixation operation the scytoblastema after dyeing is carried out fixation; Fixing operation after above-mentioned last washing step again, this fixedly operation be to be to carry out among the 3.0-3.2 at pH value with the zirconium tanning material, fixedly do not make scytoblastema yielding and further scytoblastema is carried out fixation by this regular worker's ordered pair scytoblastema.
Above-mentioned fixation operation is such: calculate with the scytoblastema of handling 100 weight parts, add the water of 45-50 ℃ of 80-100 weight part in rotary drum, rotated 15-20 minute; The formic acid that adds the 0.3-0.5 weight part then rotated 15-20 minute, added the formic acid of 0.3-0.5 weight part again, rotated 15-20 minute again, and making pH value is 3.8-4.0; The cationic fixing agent that adds the 1.2-1.5 weight part at last rotated 45-60 minute.
The said fixing operation is such: calculate with the scytoblastema of handling 100 weight parts, add the water of 35-40 ℃ of 100-120 weight part, the formic acid of 0.3-0.5 weight part in rotary drum, rotated 10-15 minute; The zirconium tanning agent that adds the 1.5-2.0 weight part then, making pH value is 3.0-3.2, rotates 45-60 minute.
After adopting such scheme, the manufacture method of a kind of washable suede of the present invention is carried out fixation operation and washing step for the third time successively between dyeing process and stuffing operation, by this fixation operation the scytoblastema after dyeing is carried out fixation; Fixing operation after the 4th washing step is again carried out solid shape by this regular worker's ordered pair scytoblastema and is not made scytoblastema yielding and further scytoblastema is carried out fixation.Suede with the inventive method is made has colour-fast, indeformable characteristics, and with the product that suede of the present invention is made, the nursing after being convenient to wear can be cleaned in washing machine, wash afterwards indeformable, colour-fast, fabric inside that can polluted product.
Embodiment
The manufacture method of a kind of washable suede of the present invention is achieved by the following scheme:
One, prepares scytoblastema: the suede embryo of 100 selected weight parts is placed in the rotary drum.
Two, backwater: in being placed with the rotary drum of scytoblastema, add the water of 45 ℃ of 100 weight parts, the AP-C grease-removing agent of 0.5 weight part, the SAF nonionic of 0.3 weight part and return humectant, rotated 120 minutes.
Three, retanning: water is drained, add the water of 35 ℃ of 80 weight parts, the formic acid of 0.3 weight part in addition, rotated 10 minutes, making pH value is 3.3-3.5; Add the chromium powder of 0.6 weight part, the syntannin NA of 1.5 weight parts again, rotated 90 minutes; Add the sodium formiate of 1.0 weight parts again, and rotated 30 minutes; The sodium bicarbonate that adds 0.4 weight part again rotated 20 minutes; The last sodium bicarbonate that adds 0.4 weight part again rotated 20 minutes, spent the night, and making pH value is 3.9-4.1.
Four, washing: scytoblastema and rotary drum are washed with clear water.
Five, neutralization: water is drained, add in addition water, 2.5 weight parts of 30 ℃ of 100 weight parts sodium formiate, 2.0 weight parts in and tannin PAK-S, rotated 20 minutes; Add the sodium bicarbonate of 1.5 weight parts, the bicarbonate of ammonia of 1.5 weight parts again, rotated 100 minutes, making pH value is 5.5-6.0.
Six, washing for the second time: scytoblastema and rotary drum are washed with clear water.
Seven, dyeing: water is drained, add the water of 30 weight part normal temperature, the ammoniacal liquor of 1.5 weight parts, the dyeing auxiliary of 1.5 weight parts in addition, rotated 10 minutes; Add dyestuff, the synthetic filling tannin PR of 1.5 weight parts, the dispersion tannin OS of 1.5 weight parts of 3 weight parts again, rotate 60-90 minute until the saturating heart.
Eight, fixation: water is drained, add the water of 50 ℃ of 100 weight parts in addition, rotated 15 minutes; The formic acid that adds 0.5 weight part then rotated 15 minutes, added the formic acid of 0.5 weight part again, rotated 15 minutes again, and making pH value is 3.8-4.0; The cationic fixing agent RD-A that adds 1.5 weight parts at last rotated 45 minutes.
Nine, washing for the third time: scytoblastema and rotary drum are washed with clear water.
Ten, stuffing: water is drained, add the water of 50 ℃ of 100 weight parts, the lanolin of 2.0 weight parts, the synthetic fat liquor of 4.0 weight parts, the phosphorylation synthetic oil of 4.0 weight parts in addition, rotated 60 minutes, and added 2.0 parts by weight of acrylic resins again, rotated 30 minutes.
