Background technology
Cotton fiber is in growth course; content of cellulose increases with the increase of maturity; also has a certain amount of material that in the cotton fiber growth, plays protective effect in addition; and the impurity that generates in the bio-metabolic process; long altogether with the cellulose symbiosis, these materials are called cellulosic commensal or accompaniment.The cellulose commensal mainly contains pectin substance, protein, waxy substance, natural colouring matter etc., the cotton seed hulls fragment of carrying secretly in addition when stripping cotton fiber.The shared ratio of commensal reduces with the raising of maturity of cotton fiber.
Cotton fiber is a hydrophilic fibre from chemical constitution, and good hygroscopicity should be arranged.But because the existence of commensal makes that the hygroscopicity of cotton fiber is very poor, can not satisfy the needs of printing and dyeing processing, can influence dyeing qualities such as dyefastness, dyeing uniformity and colour brightness, and can't embody the good wearability of cotton fabrics.
Be intended to remove the commensal of cotton fiber, improve the moisture pick-up properties of cotton fabrics, the pre-treatment of dying of satisfying the needs of dyeing and finishing processing is commonly referred to as kiering or concise.Printing and dyeing both at home and abroad always and adopting traditional alkali pretreatment that COTTON FABRIC is carried out pre-treatment in the processing, to remove various cotton fiber commensal impurity such as pectic substance, cotton wax, improve the wettability and the outward appearance of COTTON FABRIC, follow-up dyeing, stamp and arrangement processing are carried out smoothly.Traditional alkaline scouring method is to be the main agent of practicing with NaOH, be aided with scouring agent (surfactant), sodium metasilicate, sodium sulfite, sodium phosphate etc. and help experienced agent, under the acting in conjunction of these digesting agents, make natural impurity on the cotton fiber that a series of physicochemical change take place and removed wholly or in part.This technology exists water consumption, energy consumption big, waste discharge alkalescence big (pH＞11), dark, the poor disadvantages such as (COD are up to thousands of mg/L) of biodegradable of colourity, the pollution sources of dyeing maximum have been become, severe contamination ecological environment, simultaneously also cotton fiber is caused bigger damage, influence the quality of COTTON FABRIC.
Except chemical method, the present also commensal in research and utilization biological method removal cotton fiber to reduce the damage of chemical reagent to cotton fiber, alleviates the pollution of kiering waste water to environment.
Abroad started the upsurge of biology enzyme since nineteen nineties in research aspect the cotton pretreatment, Denmark Novozymes Company and Osaka, Japan university develop respectively after alkaline pectase and the protopectinase, and the biology enzyme pretreatment technology is further developed.The selection of enzyme is paid attention in the research of relevant Bio-Enzyme Pretreatment of Cotton Fabric at first both at home and abroad, and single enzyme is to improving the effect of cotton fiber wettability emphatically.Began to turn to the different enzymes of research to mix the complex enzyme of back composition in recent years to improving the synergy of cotton fiber wettability, its emphasis is pectase and cellulase, or add protease, lipase, at, piece together with the back cotton pretreatment is had certain synergy, can remove the impurity on the cotton fiber effectively, also there is a certain distance on the effect but compare, still remains on the enzyme preparation kind is selected, to be furtherd investigate with alkali treatment.Domestic multiple so-called commercial complex enzyme formulation appearred in recent years, but these products mostly are biology enzyme pieces together the product that mixes mutually with chemicals (the especially mixture of alkali), that have even just do not have any enzyme preparation composition at all, and must use (100%H when using up to 10g/L～15g/L
2O
2) hydrogen peroxide carry out oxygen and float processing, its alkali consumption height, the oxidation fierceness easily makes fabric impaired.In addition, although these complex enzyme kinds are a lot, on producing, applied as yet.And the alkaline pectase that Novozymes Company released also is difficult to adapt to the characteristics of China's COTTON FABRIC, also is among the application study.
