Abstract
The invention mainly discloses a bleaching pre-processing process for a pure cotton padding cloth. The process consists of six steps: stretching the cloth; sewing; singeing; scouring; bleaching; and drying, and has the innovation that the bleaching process is one-step enzyme-oxidation bleaching which comprises the following steps of: steaming the padding cloth for 65 minutes at the temperature of 100.5+/-0.5 DEG C by using mixed bleaching solution containing scouring enzyme with pH value ranging from 10 to 11; and performing open washing on the bleached padding cloth for three times with clean water at the temperature of between 85 and 90 DEG C. The process has the advantage of realizing bleaching at one time because the biological enzyme is used as one of the raw materials for bleaching. The process simplifies the working procedure, reduces the damage to the padding cloth fiber and contributes to environmental protection.
Description
Technical field
The present invention relates to a kind of bleaching pre-processing process of pure cotton padding cloth, be specifically related to a kind of minimizing chlorine and float step, realize the bleaching pre-processing process of environment amenable pure cotton padding cloth.
Background technology
Conventional pure cotton padding cloth bleaching process is: stand cloth, margin to seam, singe, destarch, advance that pan boiling refining, the washing that takes the dish out of the pot, chlorine are floated, washing, dechlorination, washing, open-width, oxygen float, dry, and is organized into finished product after at last.
The shortcoming of this technology is:
1, technological process is many: in bleaching process, mainly contain twice bleaching: chlorine floats with oxygen and floats, and the additional step of preface before and after all having in the middle of twice bleaching, like this, causes that technological process is many, activity time is long, causes cost up.
2, bleaching process is unfriendly to environment: in the technology of routine, rinsing is floated to float with oxygen by chlorine and is constituted, and wherein, can discharge chlorine when chlorine floats, and to environment structure harm, is not suitable for present environmental protection concept.
3, this bleaching process is bigger to lining cloth damage: because chlorine floats what float employing with oxygen is chemical agent, therefore bigger to the damage of fiber, makes that the final lining cloth grammes per square metre that forms is on the low side.
Summary of the invention
Main task of the present invention is to provide a kind of bleaching pre-processing process of pure cotton padding cloth, is specifically related to a kind of employing biology enzyme as one of bleaching raw material, reaches the once purpose of bleaching.This technology had both reduced operation, made the damage of lining cloth fiber reduce again, and also was beneficial to environmental protection.
In order to solve above technical problem, the bleaching pre-processing process of a kind of pure cotton padding cloth of the present invention, described technology by stand cloth, margin to seam, singe, boiling-off, bleaching, oven dry six big steps constitute, its innovative point is: described bleaching process is a step enzyme oxygen bleaching: adopt the mixed bleach solution that contains scouring enzyme of ph value at 10-11, under 100.5 ± 0.5 ℃ temperature, lining cloth gas was steamed 65 minutes then, and then the lining cloth after the bleaching is got final product for three times with the temperature open washing of clear water with 85-90 ℃.
Further, the constituent mass percentage of the described mixed bleach solution that contains scouring enzyme is as follows: 188 scouring enzyme 1-4%, and hydrogen peroxide: 0.8-1.2%, waterglass: 0.9-1.5%, refining agent: 0.3-0.6%, all the other are the aqueous solution.
The invention has the advantages that:
1, existing technological process is shortened greatly, has improved work efficiency, conserve water, electricity, and do not need chlorine to float, and the discharging of chlorine when so just having reduced bleaching, thus stopped because of the pollution of twice bleaching environment.
2, in the technology of the present invention since adopted biology enzyme as the bleaching raw material; thereby reached the protection to fiber, reduced the damage that the chemical reagent bleaching brings, so wanting of the more former operation of fabric strength after the bleaching pre-treatment is high; feel is more former technology soft also, and fabric weight is heavier relatively.
The specific embodiment
Pure cotton padding cloth enzyme oxygen bleaching pre-treatment process of the present invention by stand cloth, margin to seam, singe, boiling-off, bleaching, oven dry six big steps constitute, specifically technology is as follows:
At first, stand cloth: lining cloth is neatly paved, and then the cloth Mo Yin that buys oil, print position is transferred to apart from leftover of bolt of cloth 20-25cm.
Then, margin to seam: margin to seam promptly refers to two lining cloth to be connected to a cloth by making.General margin to seam requires: the margin to seam pin is close: 32-30 pin/10cm, suture hangover: 2-3cm.
Margin to seam is singed: singe and also singe for routine, can carry out single or double as requested and singe after handling.In the present invention, the temperature of burner is 800-900 ℃ when singing, the speed of lining cloth be controlled at 120-140 rice/minute, the number of times of singing is: positive and negative each twice.The lining cloth effect of singing of back gained of singing is that cleanliness gets final product more than or equal to 3 grades.
Next will carry out boiling-off to the lining cloth of singing after handling: the reagent of boiling-off is made of following component: NaOH:35 ± 2g/l, the CE-1 refining agent that Nantong Si Ente produces: 6g/l, all the other are water.Mentioned reagent is placed in the groove, heat after 70-75 ℃, with lining cloth with 55-60 rice/minute speed from its reagent, pad through twice, guarantee the time of lining cloth in reagent about 1.5 minutes, again through under 100.5 ± 0.5 ℃ the temperature lining cloth gas being steamed 65 minutes.Then, the lining cloth after the boiling-off is carried out open washing 3 times in clear water, the open washing temperature remains on 90 ℃ and gets final product.
Next carry out enzyme oxygen and float operation, the reagent in this operation is: 188 scouring enzyme: 20g/l, and hydrogen peroxide: 10.5g/l, waterglass: 13g/l, the CE-1 refining agent that Nantong Si Ente produces: 4g/l, all the other are water; Above reagent is transferred to the ph value between 10-11, then with lining cloth with 50-55 rice/minute speed from its reagent, pad through twice, the assurance time of lining cloth in reagent through under 100.5 ± 0.5 ℃ the temperature lining cloth gas being steamed 65 minutes, is finished bleaching again about 1.5 minutes.And then to the lining cloth after the bleaching with clear water with 85-90 ℃ temperature open washing three times, the ph when making the lining cloth cropping is to being controlled at 6-6.5.
At last, the lining cloth after the bleaching is carried out conventional oven dry handle and the back arrangement, make the finished product lining cloth.
