Description
【Technical field】
The invention belongs to degumming technical field, and in particular to a kind of natural silk degumming agent for improving degumming rate and its preparation side
Method.
【Background technology】
Silk is concretionary fiber, referred to as silk after silk liquid in silkworm body spues through spinning.It is by two cross sections
Constituted in fibroin (also known as fibroin) the outsourcing silk gum of nearly triangle or half elliptic, also pigment, oily wax and inorganic matter, they are deposited
In being silk gum.Wherein silk gum has certain protective effect to fibroin, but if content is excessive, influence whether fibroin gloss and
The technique processing of feel and silk fiber, and the impurity such as grease, wax can bring certain difficulty to post-processing.Therefore, in dye
Before whole processing, it is necessary to first remove the debris such as most of silk gum, grease, wax, make that silk fiber is soft, loose, cleaning.
Fibroin and silk gum are all protein, and ultimate constituent is amino acid, but their amino acid classes and are contained
Amount, molecules align, supramolecular structure and present position all have very big difference.Sericin belongs to globular protein, therein
Polar Amides acid content is more more than fibroin albumen, and molecules align is disorderly, and crystallinity is low.And fibroin protein is linear,
Simple structure and closely, the degree of orientation and crystallinity are higher.Due to the difference on the Nomenclature Composition and Structure of Complexes of fibroin and silk gum, result in
They are some different in nature in dissolubility, water-disintegrable and chemical stability etc..Such as in water, fibroin is not dissolved, silk gum
Then can expanded and dissolving；In the presence of acid, alkali or enzyme, silk gum is easier to be decomposed, and fibroin then shows suitable stability.
The concise essence of silk fabric is exactly these differences using fibroin and silk gum, using appropriate technique and equipment, removing silk gum
Retain fibroin, so as to reach the purpose of degumming.
The Degumming method of current silk is divided into microbial degumming and the class of chemical Degumming two, and chemical Degumming is again according to the change for using
Learn medicine difference and have alkali degumming, the degumming of soap alkali, sour degumming.But at present these method generally existing degumming efficiency is low asks
Topic, it is impossible to carry out degumming well, so that the application of silk is largely have impact on, while in order to pursue degumming effect higher
Rate often takes the means that different degumming modes are combined, although so can to a certain extent improve degumming rate, result
It is often unsatisfactory, while also result in problem with high costs.
【The content of the invention】
Present invention offer is a kind of to improve natural silk degumming agent of degumming rate and preparation method thereof, to solve existing natural silk degumming
There are problems that degumming efficiency it is low or.The silkworm processed using the natural silk degumming agent for improving degumming rate of the invention
Silk, silk fracture strength loss loses smaller with extension at break, and the silk gum before degumming in silk substantially takes off, and effectively improves
The whiteness of silk, glossiness and dyeability.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of natural silk degumming agent for improving degumming rate, in units of weight portion, including following raw material：Ammoniacal liquor 104-152
Part, sodium metasilicate 42-78 parts, surfactant 11-22 parts, bleeding agent 1.8-4.2 parts, dispersant 1.2-2.3 parts, conditioning agent 2-
3.4 parts, cosolvent 1.8-3.2 parts, stabilizer 0.9-1.4 parts.
Further, the mass concentration of the ammoniacal liquor is 22%-28%.
Further, the surfactant is polyacrylamide.
Further, the bleeding agent is alkyl benzene sulphonate potassium.
Further, the dispersant is laruyl alcohol potassium sulfate.
Further, the conditioning agent is acetic acid.
Further, the cosolvent is sodium salicylate.
Further, the stabilizer is boron nitride.
The present invention also provides a kind of preparation method of the natural silk degumming agent for improving degumming rate, comprises the following steps：
S1：Ammoniacal liquor, sodium metasilicate are mixed, 45-48 DEG C of stirring and dissolving is warming up to, mixed liquor I is obtained；
S2：Surfactant, bleeding agent, dispersant, cosolvent are added to mixed liquor I obtained in step S1,52- is heated to
58 DEG C, be 130-185W in ultrasonic power, and rotating speed is that 200-300r/min stirs 18-26min, and mixed liquor II is obtained；
S3：Stop heating and ul-trasonic irradiation, stabilizer is added to mixed liquor II obtained in step S2, be 200- in rotating speed
6-8min is stirred under 300r/min, mixed liquor III is obtained；
S4：To conditioning agent and water is added in mixed liquor III obtained in step S3, the natural silk degumming that can improve degumming rate is obtained
Agent.
Further, pH value is made to be 9.2-10.5 after conditioning agent and water are added in step S4.
The invention has the advantages that：
(1) silk that the natural silk degumming agent for improving degumming rate using of the invention is processed, the loss of silk fracture strength with
Extension at break loss is smaller, and the silk gum before degumming in silk substantially takes off, effectively increase the whiteness of silk, glossiness and
Dyeability, while making its soft smooth.So that obtained silk fabrics glossiness and feel preferably, are carried in subsequent treatment
The quality of fabric high；
(2) natural silk degumming agent treatment silk low cost and the efficiency high for improving degumming rate of the invention.
