Abstract
The present invention relates to the cold-rolling heap printing and dyeing pretreating technology that a kind of dyeing uses, its technological process is: grey cloth, and---cold rolling---clot is banked up---washes---oven dry---semi-products, it adopts homemade serial auxiliary agent substituting import one auxiliary agent fully, the semi-products quality of producing meets the requirements fully, even surpassed external like product quality, it with the moving back of routine, boil, bleaching process compares, and not only shortened technological process, reduce cost, but also improved the quality of semi-products.
Description
The present invention relates to the dyeing pre-treatment process, particularly a kind of cold-rolling heap printing and dyeing pretreating technology.
Cold-rolling heap printing and dyeing pretreating technology is the efficient pretreating technology for printing and dyeing of the popular fabric of the eighties, has the production efficiency height, quality is good, energy savings, characteristics such as the simple operation easily of equipment, only have minority developed country to begin one's study in the world, China has listed this technology in focus development and the promotion project in " eight or five " ruleization.China has only indivedual producers to utilize the import auxiliary agent to carry out technical study at present, produces in enormous quantities along not forming.
Cold-rolling heap printing and dyeing pretreating technology is based on hydrogen peroxide process, adopt efficient refining to float serial auxiliary agent, realize destarch, boiling-off, bleaching unification, its technological process be grey cloth → cold rolling → clot bank up → wash → dry → semi-products, the external West Germany bus husband company that generally acknowledges adopts this technological process exactly, we analyze and research to cold pad-batch additive and cold-pad-batch process that West Germany bus husband company produces according to this technological process, the cold pad-batch additive of discovery West Germany bus husband company is the cost height not only, and effect is not very good.Extensive application often is not so good as present chlorine bleaching process or oxygen bleaching process and calculates.Therefore, the resource of basing on our country works out low cost, and can satisfy the cold rolling heap prescription of technological requirement, becomes a big problem of domestic dyeing.
Task of the present invention is exactly in order to provide a kind of China that is suitable for to produce the cold-rolling heap printing and dyeing pretreating technology that uses, to adopt homemade serial auxiliary agent substituting import one auxiliary agent, so that reduce production costs, improving the printing quality of fabric.
Technological principle of the present invention is with H by means of bleeding agent efficiently
2O
2Infiltrate fabric fibre rapidly with caustic soda etc., utilizing makes the stabilizing agent of decomposing hydrogen dioxide solution that hydrogen peroxide is slowly decomposed more reposefully, through reaction at ambient temperature for a long time, slurry on the fabric is decomposed, pectic substance, cotton seed hulls, wax, pigment etc. are damaged, utilize high temperature (more than 90 ℃) washing again, the impurity that is easy to hydrolysis is removed rapidly, the impurity that is not easy to hydrolysis is removed under the emulsifying agent effect.Thereby reach the technological effect of conventional destarch, boiling-off, bleaching three operations.
The present invention adopt grey cloth → cold rolling → clot bank up → wash → dry → technological process of semi-products, wherein in cold rolling process, the employing padding machine pads, pick-up is more than 90%, contains hydrogen peroxide 50～90ml of 30% in every liter of cold rolling liquid, caustic soda 10～30g stabilizing agent A25～35g of 100%, penetrating agent JFC 3～5ml, detergent 3～5ml commonly used, auxiliary agent JU4～6g, all the other are water.In washing step, adopt the high-temperature water more than 90 ℃, contain efficient detergent powder 4g in every premium on currency dilution, the detergent 2ml clot commonly used operation of banking up is to bank up at ambient temperature 15～17 hours.
To the cold-pad-batch process method of described process of the invention described above and West Germany bus husband company produce 21
S* 21
S108 * 58 all cotton yarn semi-products carry out test comparison, after it the results are shown in Table the 1(literary composition).
The semi-products of producing by the present invention are compared with the semi-products of producing by the cold-pad-batch process method of West Germany bus husband company as seen from Table 1, a little better on the semi-products whiteness of the present invention, feel is a bit weaker, go cotton assorted situation all better, brute force has all surpassed standard-required, can satisfy bleached cotton fabric, dyeing and the calico quality requirement to fabric pretreatment basically.
To process of the present invention and conventional move back, boil, the bleaching process method is produced 21
S* 14
S42 * 44 single-side pile semi-products carry out test comparison, and it the results are shown in Table 2(and sees the literary composition back).
As seen from Table 2 the present invention with conventional move back, boil, the semi-products of bleaching process compare, every specification requirement all is more or less the same.
These two kinds of semi-products are carried out the full-page proof stamp, and the goods behind the stamp are tested, the results are shown in Table 3.The technological process of its stamp is respectively:
Semi-products of the present invention
→ grab suede
Routine is moved back, is boiled, bleaching process semi-products → go up soft
→ wash suede → starching → stamp → evaporate → saponification → tentering
Semi-products printing tests result (21 is moved back, boils, floated to cold rolling heap semi-products calico and routine
S* 14
S442 * 44 grid printing suedes) see Table 3(and see the literary composition back).
As seen from Table 3 with method of the present invention and with routine move back, boil, the bleaching process method all meets double product requirements of printing and dyeing.
In sum, adopt process of the present invention, the semi-products quality of producing such as flannelette, cotton, textile cloth, corduroy of grabbing meet the requirements fully, met or exceeded external like product quality, it with routine move back, boil, bleaching process compares, shortened technological process greatly, a large amount of water, electricity, vapour consumption have been reduced, make printing and dyeing processing pre-treatment cost reduce about 1/2, simultaneously need not go up softener and just can directly grab suede, and can reduce and grab suede road number (1～2 road), the fine hair quality increases, reduce wrinkle, improved quality.Serial auxiliary formula of the present invention is to utilize homemade resource, and cost is low, can satisfy cold-rolling heap printing and dyeing pre-treatment requirement fully.
Below describe technological process of the present invention in detail.
Technological process:
Grey cloth → (singing) → cold rolling → clot is banked up → hot water wash → cold wash → oven dry → semi-products
Cold rolling process is to adopt padding machine to pad, and pick-up is 90%, adds auxiliary agent in cold rolling liquid.Composition in every liter of cold rolling liquid sees Table 4.
The composition consumption
30% hydrogen peroxide 70ml
100% caustic soda 20g
Stabilizing agent A 30g
Penetrating agent JFC 4ml
8801 detergent 4ml
Auxiliary agent JU 5g
Water all the other
The clot operation of banking up is that the fabric after cold rolling is spooled the back is tight with plastic sheeting wrapping, places at ambient temperature 16 hours.
The hot water wash operation is the high-temperature-hot-water that adopts more than 95 ℃, and the inside adds water washing assistant and water, washes at the case of soaping, and contains efficient detergent powder 4g in every premium on currency dilution, 8801 detergent 2ml, and all the other are water.
Cold wash adopts 50～60 ℃ warm water to carry out three washings.
