Abstract
An alkaline pectinase product as assistant for scouring cotton fabrics is prepared from Bacillus pumilus (CCTCC No.M203042) through deep liquid fermenting and compounding. A technology for immersing scouring or steam scouring of cotton fabric is also disclosed. Its advantages are low cost and high quality of cotton fabric.
Description
Technical field
The present invention is the composite of a kind of alkaline pectin enzyme preparation and uses.The refining processing and a kind of weaving biological enzyme formulation that relate to cotton-spinning fabric.
Background technology
Crude fabric after the destarch, its water imbibition and whiteness are all unsatisfactory.Tradition is concise after concentrated base (pH13～14) kiering, needs to consume a large amount of clear water and carries out rinsing.Meanwhile just can produce large amount of sewage, environment is produced greatly influence,, removing non-cellulosic impurity, thereby greatly reduce influence environment so it is concise that people adopt special biology enzyme that fabric is carried out.For example, add pectase decompose pectin matter, and impurity such as lipid that will adhere to and protein are removed from the cotton fiber surface together.Utilize enzyme to carry out refining processing, not only can not influence cellulosic skeleton usually, and can make and reduce to minimum the destruction of cotton fiber.Particularly the good characteristic of alkaline pectase in the cotton spinning preliminary treatment makes it more and more to be subjected to people's attention.
Summary of the invention
The composite and methods for using them that the purpose of this invention is to provide a kind of alkaline pectin enzyme preparation.Use enzyme preparation of the present invention can change existing traditional cotton textiles refining processing technology effectively, improve environment and product quality.Technical scheme of the present invention, a bacillus pumilus (Bacillus pumilus) WSH03-09 through obtaining from row filter now has been preserved in Wuhan China typical culture collection center, numbering CCTCC NO:M203042.The alkaline pectase that liquid deep layer fermenting obtains compositely obtains can be used for cotton-spinning fabric processing (refining process) enzyme preparation of coming unstuck.Concrete preparing process is as follows: the enzyme after the zymotic fluid flocculation and the processing of saltouing is dissolved in following system (g/l): ethanol 20～60, glycerine 100～150, calcium chloride 2～5, Sodium Benzoate 0.5～2.The work of composite enzyme preparation neutral and alkali pectase enzyme is 50～400u/ml.
The composite enzyme preparation of this alkaline pectase can be used for the refining processing technology of COTTON FABRIC.Process conditions are: enzyme dosage 0.5～3g/l, and the Applicable temperature scope is 40～65 ℃, the pH scope is 8.0～10.0, processing time 60～120min.
Beneficial effect of the present invention, described composite enzyme preparation can be used for the refining processing of COTTON FABRIC, can replace traditional alkaline scouring technology, can reduce production costs, and improves the ecological environment and improves the quality of products.
Aspect production cost: can save a large amount of process waters, production time, energy consumption, raw material (caustic alkali) etc., reduce disposal cost simultaneously to waste water;
Aspect ecological environment: reduced to salt content in the environmental emission water and COD etc.;
Aspect product quality: owing to avoided the damage of highly basic to cotton fiber, thus make fabric have excellent handle and dyeing property.
The biological material specimens preservation
Bacillus pumilus, preservation date on May 21st, 2003, depositary institution's title and abbreviation: Chinese typical culture collection center C CTCC, deposit number NO:M203042.
The specific embodiment
Embodiment 1
Cotton fabrics dipping refining process: water pretreating fabrics (90～100 ℃) 1～5min, handle with alkaline pectase again, promptly concise.(process conditions are: enzyme dosage 0.5～3g/l, pH8～9,50～65 ℃ of temperature, processing time 60～120min, nonionic surface active agent 0.5～10g/l).Use the clear water rinsing at last.
Embodiment 2
Cotton fabrics decatize refining process: behind fabric desizing, handle with alkaline pectase, promptly concise.(process conditions are: enzyme dosage 0.5～3g/l, pH8～9,50～65 ℃ of temperature, processing time 60～120min, nonionic surface active agent 0.5～10g/l).Use the clear water rinsing at last.
