Abstract
The invention provides an efficient short-flow pre-treating process for high-grade high-density cotton fabrics in order to remove the impurity and slurry from cotton woven. The process comprises the steps of feeding cloth, hot washing, padding enzyme solution, steaming, hot washing, warm washing, padding floating solution, wet steaming, hot washing, warm washing and drying. The specific step is to desize with wide-temperature enzyme on a pre-treated desizing section, boiling, whitening a whitening section with alkali oxygen technique and a wet short steaming device in order to remove the impurity and slurry from cotton fibers, for the purpose of shorting the process flow and decreasing the consumption. The invention has the advantages that (1) the process flow is shortened, the working efficiency is promoted and the product quality is promoted, (2) the harmful wastes are decreased and the environment is protected, and (3) the consumption of water, steam and energy is decreased and the manufacturing cost is lowered.
Description
(1) technical field
The present invention relates to a kind of fabric printing pre-treatment process of field of textiles, particularly relate to a kind of high Efficient Short Process Pretreatment that is applied to the high-count and high-density pure cotton fabric.
(2) background technology
Along with the enforcement of recycling economy rules, energy savings reduces the fundamental state policy that disposal of pollutants will become China, is long-term strategic task.Because the contradiction between rapid development of economy and the energy supply and demand increases the weight of day by day, causes rising steadily of energy prices in recent years, the expense of energy resource consumption and the proportion of entreprise cost rise year by year.Have competitiveness on the product price for making, reducing cost of the necessary every possible means of making use of momentum then is one of effective ways of energy-saving and emission-reduction by improving technology.
COTTON FABRIC needs to carry out pre-treatment before dyeing and finishing, to remove impurity and the slurry in the fabric.Impurity in the COTTON FABRIC is divided into natural impurity and slurry two big classes.Natural impurity: approximately contain 6～10% in cotton fiber, comprise wax, ash content, nitrogen substance, organic acid, pectin substance, polysaccharide, undetermined part etc., this part impurity is mainly removed by bleaching process.Slurry: mainly be before weaving cotton cloth warp thread to be carried out starching and retains on the cloth cover.The kind that the rate of sizing is looked fabric is different and different, is generally 4～8%, and the close weave class is up to 8～14%.In recent years, be to improve loom speed, the textile sizing rate also has greater than 14%.Slurry is mainly removed by the destarch operation.
Traditional general employing of conventional pre-treatment process is boiled continuously and is floated machine, is a kind of more traditional kiering equipment.Its technological process is: advance cloth → pad kiering liquid → bar grid steam box (70min, 100 ℃ ,) → 4 steam tank-washer wash → pad bleaching liquid → bar grid steam box (45min, 100 ℃) → heat wash → temperature washes → dries.Its weak point is: during (1) kiering, and work liquid measure big (about 3500L), thereby be fit to concentratedly carry out kiering and bleaching, produce 15 myriametres continuously.(2) digesting agent requires height, at 30～50g/L NaOH, in the time of 100 ℃, needs to keep never degenerating in 80 hours, more can not floating oil.When (3) the control bleaching liquor padded working solution, left, center, right band liquid measure required to be consistent.For example: bar grid decatize case, after fabric pads working solution, enter the decatize preheating zone, be raised to 100 ℃, by controlling device fabric neatly is stacked on the bar grid of upper strata then, along with the motion of sports bars grid, transfer to again on lower floor's bar grid.The 70min that banks up during its kiering, 100 ℃ of saturated vapors, the 45min that banks up during bleaching, 100 ℃ of saturated vapors; Its result: 1. be prone to fold; 2. the left, center, right whiteness is inconsistent; 3. the left, center, right capillary effect is inconsistent.
My company adopts the high efficiency shortened process pretreatment technology to the high-count and high-density pure cotton fabric, promptly be moving back of pre-treatment to be boiled (destarch) section adopt wide temperature enzyme desizing, kiering, bleaching section employing alkali oxygen technology in conjunction with wet short steaming equipment, are easy to by impurity and slurry in the washing removal fiber.
At present, still do not find about the open source literature of so short process pretreatment technology.
(3) summary of the invention
The objective of the invention is based on energy-saving and emission-reduction, shortened process is enhanced productivity, and improves the quality of products, and a kind of high-count and high-density COTTON FABRIC high Efficient Short Process Pretreatment is provided.
Technical scheme of the present invention is to realize like this.
A kind of high-count and high-density COTTON FABRIC high Efficient Short Process Pretreatment, purpose are impurity and the slurries of removing in the COTTON FABRIC, comprise into conventional operations such as cloth, washing, oven dry in its technological process.The technological process of this pre-treatment is: advance cloth, heat wash, pad that enzyme working solution, decatize, heat are washed, temperature is washed, pad boil float working solution, wetly steam, heat is washed, temperature is washed, dry.
Its critical process technical conditions are as follows:
1, hot washing process condition:
Temperature: 80 ℃, time: 1min, bleeding agent: 1g/L.
2, pad the enzyme working solution:
The enzyme desizing Working solution prescription is:

The high efficiency shortened process pretreatment technology characteristics of this programme:
1, adopts abbreviated system, its objective is in order to improve pre-treatment speed, energy efficient, reduce water consumption, make treatment fluid soak into as early as possible, absorb, require auxiliary agent to have infiltration rapidly, emulsifying ability is strong, the detergency height, high temperature resistant, anti-concentrated base, the characteristics of anti-hard water, through exploring the composite T of going out, S auxiliary agent, i.e. tween: sapn=4:1, can adapt to this technology preferably.
2, move back and boil steam box and go out to suck alkali PH detection case:
Common process (NaOH)＞10g/L (pH value is about 13～14),
Enzymatic process (this programme) PH:7.
3, from technological process as can be seen, short flow process is moved back, boils, is floated three segment process and compares with routine, need not guipure decatize case, replace with wet steaming equipment, enzyme desizing is easily washed, and 5 are steamed tank-washer after the former destarch, (3 heat are washed now only to steam tank-washer with 4,1 cold wash) finish, full machine flow process is short, reduces more than 12 meters than original process equipment spread length.
Conclusion
1, this technology is that efficient and environment-friendly type auxiliary agent and new cleanproduction process combine, for pretreatment procedure is formulated reasonable flow process, and the combining process energy savings, reducing to pollute and implement cleaner production provides foundation.
2, enzyme desizing technology is moved back the section of boiling owing to alkali-free, and sewage effluent PH only is 7, is a kind of environment-protective process of cleaner production therefore.
3, the high efficiency shortened process relative cost is lower, reduces by 0.03 yuan for every meter than conventional three segment process.
4, the semi-products index of whiteness and capillary effect can reach the technological requirement of dyeing and calico fully.
5, owing to boil the unique choice of equipment of the section of floating, saved steam, the reaction time is short, saves 3 tons/myriametre of steam, and electric 18Kw/ myriametre has shortened the production cycle, has reduced labor strength.
Comprehensively described: the high Efficient Short Process Pretreatment equipment investment is few, and operating cost is low, is the technology of a kind of cleaner production and better economic benefit, and simultaneously every semi-products index can satisfy behind dyeing or the stamp operation fully to the technological requirement of semi-products.
