Abstract
The invention discloses a kind of biological enzyme silk fiber scouring agent, in parts by weight, including following components：100 parts of compound protease, 40 50 parts of fermentation of Aspergillus niger liquid, 12 18 parts of laccase, 20 38 parts of cellulase, 30 50 parts of stabilizer, 12 19 parts of bleeding agent, 25 parts of Lanthanum Isopropoxide, 36 parts of amyl group phenol polyethenoxy ether.Scouring agent obtained by the application can effectively remove the impurity such as silk gum and grease on silk fiber, required concise mild condition, to equipment requirement than relatively low, and silk fiber will not be damaged.And the scouring agent of the application can keep good stability, service life is longer.
Description
Technical field
The present invention relates to textile auxiliary field, more particularly to a kind of biological enzyme silk fiber scouring agent.
Background technology
Silk is a kind of natural protein fibre, is that the silk liquid solidification secreted out of by silk glands in silkworm body forms.Silk is former
Removed in material outside main component fibroin, also containing the impurity such as silk gum and a small amount of grease, wax, hair, grass cuttings.It is inside silk
Fibroin, outsourcing silk gum, the content of fibroin and silk gum are different because silk species is different.Silk gum shields to fibroin, but silk
Glue can excessively influence the gloss of silk, therefore removing unit sub-wire glue is needed in silk process so that it is peculiar that silk obtains its
Gloss and feel.The impurity such as grease, wax, hair and grass cuttings on silk can bring certain difficulty to following process, because
This also needs to remove these impurity before processing so that silk fiber is soft, fluffy, clean.Silk processing before need by silk gum,
The process that the impurity such as grease remove is referred to as concise.
The concise of silk fiber can be divided into two kinds of situations：The first, concise, raw silk and its fabric of raw silk and its fabric
More silk gum is usually contained, other impurities are less, therefore the concise mainly degumming of such raw material；Second, silk spinning raw material
It is concise, silk spinning raw material is waste silk, piques etc. caused by the processes such as sericulture, the production of hybrid seeds, filature, and this kind of raw material type is more, of poor quality
Not larger, part material is more containing glue, and part material is more containing grease, therefore this kind of raw material is concise including degumming and oil removing.At present
The method for refining of silk has：Soap alkali is concise, open width Fast Degumming, High pressure degumming and biological enzymatic scouring.Soap alkaline process is concise to be
First carried out with alkali preliminary concise, then refining processing is carried out using soap as scouring agent, the softness of the meeting influence silk fabrics of this method
Degree and whiteness, easily damage the structure of silk fiber.Open width Fast Degumming has fast eliminating silk gum and does not damage silk fiber
The advantages of, but the Type Compound Refining Agent complicated component that this method uses, cost are higher.High pressure degumming method needs high temperature height
The condition of pressure, it is higher to equipment requirement, increase processing cost.
Biological enzymatic scouring method is to carry out refining processing to silk fiber using biology enzyme.Biology enzyme is from biological cell point
Secrete what is, main component is protein, can leave organism and be individually present, have special catalytic action.Enzyme is like it
He participates in the pilot process of reaction by catalyst, but does not consume finally, and referred to as " enzymatic is anti-for the process of this usual catalytic reaction
Should " process.The catalytic property of enzyme is special, there is the advantages of other catalyst are incomparable.The use of very little is used in enzymatic reaction
Amount can just play the catalysis efficiency of protrusion, while enzyme is green as a kind of biological agent, safe and non-toxic evil, energy complete biodegradable
Colour circle is protected.Since 20th century, the research and development of various enzymes make great progress, and have been widely used in multiple necks
Domain, especially in textile industry, a variety of working processes have been applied to it.Refining processing is carried out to silk fiber using biology enzyme,
It is green, and can have good scouring result.
The content of the invention
It is an object of the invention to provide a kind of biological enzyme silk fiber scouring agent, the scouring agent can effectively remove silkworm
The impurity such as silk gum and grease on silk fiber, required concise mild condition, to equipment requirement than relatively low, and will not be to silk fibroin
Dimension damages.And the scouring agent of the application can keep good stability, service life is longer.
It is a further object of the present invention to provide the application method of the biological enzyme silk fiber scouring agent.
To achieve the above object, the present invention uses following technical scheme：
A kind of biological enzyme silk fiber scouring agent, in parts by weight, including following components：
100 parts of compound protease, fermentation of Aspergillus niger liquid 40-50 parts, laccase 12-18 parts, cellulase 20-38 parts are stable
