background information

Carrying out environmental protection, energy-saving and emission-reduction, cleaner production is the severe task that country proposes dyeing, new technology that research application energy consumption is low, few energy-saving low-carbon that discharges pollutants is scouringed and bleaching substitute traditional alkali oxygen technique be realize sustainable development have effect measure.

Traditional pre-treatment, except singing, generally comprises the multiple working procedures such as destarch, kiering, bleaching, has the shortcomings such as technological process is long, energy consumption is large, water consumption is many, contaminated wastewater is serious.Move back, boil, float three-procedure not completely every splitting, but mutually supplement, as destarch time, there is the effect of removing part natural impurity, can alleviate the burden of kiering, and kiering has effect of further removal residual slurry, fabric whiteness is also improved, and bleaching also has the effect of further impurity elimination.The inside and outside colourist in native land all find a kind of can shortened process, simplified apparatus, reduction energy consumption, the way of ensuring the quality of products, i.e. high efficiency shortened process technique, has two-step method and one-step method at present.Two-step method has destarch, kiering, bleaching act of union and destarch, kiering to merge then bleaching, is called for short respectively D-SB method and DS-B method.One-step method generally can be divided into two kinds of cold pad-batch method and steam methods.

As far back as the 1950's of the report of existing pre-treatment abbreviated system abroad, be called at that time sinolprocess continuous bleaching.In recent years, Shortened Pretreatment had had rapid progress and greater advance at aspects such as technology, auxiliary agent and equipment, but compared with Foreign Advanced Lerel, or there is very large gap, be mainly manifested in:

(1) adopt short-flow pre-treating process also not high in the coverage rate of certain areas and kind, particularly between area, development is very uneven, some its coverage rate of advanced coastal area is up to more than 90%, and some only 20%-30% of regional coverage rate, some kind can be come completely by abbreviated system, can still boil and float three step process in traditional the moving back of employing.

(2) semi-products of short flow process cold-pad-batch process processing are of low quality: slurry does not move back clean, and impurity removes not clean (seed shell fruit collodion wax etc.).Capillary effect is not high, greatly affects Liao Hou road dyeing and finishing crudy.Trace it to its cause, mainly the key element of failing to grasp abbreviated system: webbing liquid measure is not high, temperature control is bad, it is improper that stabilizing agent is selected, last washing fails to reach requirement, particularly crucial hot alkali treatment technique fail to grasp, wash insufficient, technology preparation is unreasonable (ratio of hydrogen peroxide, caustic soda stabilizing agent is improper), optimize not, the selection of process conditions does not meet the reaction rule of abbreviated system.

(3) exploitation of auxiliary agent does not adapt to the demand for development of technique kind, fails and the exploitation synchronized development of technique kind.The quality of short process pretreatment auxiliary aid is stable not, still lacks seriation, customizations, standardization and unified testing standard.The exploitation of auxiliary agent kind can not meet abbreviated system demand for development, is particularly suitable for the exploitation of the environment-friendly type auxiliary agent of sub-abbreviated system, can not meet the requirement of process for cleanly preparing far away.

(4) exploitation of short process pretreatment corollary equipment does not catch up with abbreviated system demand for development yet.Particularly automation and electromechanical integration degree are lower.Lack online detection and the metering device of technological parameter, roll the winding apparatus overwhelming majority for passive rather than breast roll active drive.Liquid dispensing apparatus is not high feeding, and decatizing apparatus, temperature do not reach requirement, some serious steam leakage, preheating time deficiency.It is air-dry that crawler type steam box easily produces strut rail, and guide roll type steam box fabric easily moves about and crumples.So far also there is no a high temperature hot alkali treatment equipment that meets technological requirement and meet abbreviated system to require the efficient washing equipment of reaching advanced world standards.

The research and development of the ecological pretreating reagent of short flow process low temperature, restriction and the restriction to China's textile exports for the U.S. and European Union, in China existing weave dyeing and finishing technique, exist that harmful chemical residue is too high, high cost and discharge of wastewater can not guarantee environmental requirement, the problems such as vapour energy consumption is large for processing procedure electricity consumption, providing a kind of is not changing under the condition of existing equipment, reduce system temperature, needn't use caustic soda, hydrogen peroxide and reduce and use other chemical assistant as far as possible, can reach the fabric Additives Products of printing and dyeing pre-treatment all technical requirement.

The ecological pretreating reagent of low temperature, do not contain formaldehyde, APEO(alkylphenol polyoxyethylene), sodium metasilicate, phosphorus etc. be any to human body and the harmful chemical element of environment, when use, needn't add again caustic soda, hydrogen peroxide, can meet every technical requirement of printing and dyeing pre-treatment, effect is very obvious, and can process nearly all fabric such as cotton, blending.In the situation that not changing original equipment, with the plain mode directly adding, realized dyeing destarch, concise, bleach the disposable environmental protection equalization completing.This product application technology maturation, formula is stable, and raw material abundance, can meet the user demand of dye-works.

The ecological pretreating reagent of low temperature, can utilize original equipment, highly basic boiling and bleaching process are combined into a procedure, in the situation that other process conditions are all constant, reach the pretreatment technology index that traditional handicraft is produced, make like this technological operation more easy, quality is effectively controlled more, 3-5 capable of reducing using water tank when production operation, R or L steaming box, technological process is shortened greatly, and only this item is to exempt to add 3 tons, caustic soda every day, saves 100 tons/24h of steam; Saving electricity consumption 500 spends; 500 tons of using water wisely, are equivalent to save 20000 yuan of RMB above (monthly producing 200 myriametre meters) every day, and benefit is considerable.

(1) choosing with compatibility of magistery transformed.Can play a role and keep collaborative stable with other function ingredients again simultaneously, reach certain term of validity.

(2) accurately control process and the chemical environment processed.Processing procedure should be carried out according to controlledization of formula of design, must guarantee that the unbalance of effectiveness do not appear in all chemical constituents, and has variation to site technique and the in good time mechanism cushioning.

(3) reduction of cost.Magistery and accurately controlled design will bring the significantly rising of cost, must develop by strengthening research, and the scheme perfect with exquisiteness takes out consumption, and reduces the expense of each link.
