Abstract
The present invention relates to a method for preparing tinea pellionella silk by using tinea pellionella silk vesicles. The tinea pellionella silk has the same use value as natural protein fiber, such as natural silk, wool, etc. The present invention is characterized in that the degumming and the impurity removal of the tinea pellionella silk vesicles are carried out in an alkaline solution bath, and the tinea pellionella silk vesicles form tows through rough smelting, refining and hydrotherm extension. The fineness of prepared tinea pellionella silk is from 0.48 to 0.91, the break elongation rate is from 26 to 34% (dry state), and the brute force is 4.2 gram force per denier. The yield of the tinea pellionella silk prepared by the tinea pellionella silk vesicles with the method of the present invention relates to 25 to 38%. The tinea pellionella silk has luster, a soft smooth hand feel, and good light transmission, when pulled and twisted, the tinea pellionella silk generates a drone. The tinea pellionella silk has a natural silk feel, and can partially replace natural silk and wool.
Description
The present invention relates to a kind of refinement method of natural protein fibre, specifically, it is to adopt the method for the bag silk capsule that the pretty young woman tied of wild or ARTIFICIAL CULTURE by the impurity elimination of coming unstuck, hydrothermal solution drawing-off refinement silk.
As everyone knows, a bag pretty young woman is an a kind of Lepidoptera bag pretty young woman section insect, kind surplus known its kind in the whole world has 800, and known its kind reaches more than 100 kinds in China.The bag pretty young woman is a food with the plant, and feeding habits are extensive, reach 32 sections, 65 kind of plant, so be a kind of insect that endangers agricultural and forest.
Silk is the invention of great significance of Ancient Times in China, by by the secreted silk cocoon of being formed of the sericterium of giant silkworm section insect, separates the reel silk from cocoons system of relaxing through coming unstuck, boiling-off is produced, and can not reel silk from cocoons system person just be made into the silk spinning material again by doubling, slubbing, finespun.Because the raw material sources of silkworm and tussah are limited, influenced the production of silk goods, and the utilization of wild silkworm class is not paid attention at present as yet, so the exploitation of silk has the environmental benefit and the social benefit of tangible economic worth and " turning harm into good ", " turning waste into wealth ".
The silk fiber number of the inventive method preparation wants much thin than the fiber number of silk (1.2-3.5-6.5D) between 0.48-0.91D; But the elongation at break of silk is the 26-34%(dry state) and the elongation at break of silk is the 15-25%(dry state) much higher; Silk still keeps the brute force of 70-90% at 200 hours at sunshine on the light fastness; And the silk class only reaches about 50%; The dry state brute force of general silk is the 3.4-4.0 grams of force per Denier, and the dry state brute force of silk is more than 4.2 grams of force per Denier; The fibre property that other is relevant, silk is relatively more approaching or similar to the performance of silk.
The present invention is a kind of method that adopts the bag silk capsule that the pretty young woman tied of wild or ARTIFICIAL CULTURE by the impurity elimination of coming unstuck, hydrothermal solution drawing-off refinement silk.
Do not put down in writing the preparation method of silk in prior art as yet, the general wild silkworm of Ancient Times in China is adopted acetic acid to do solidification liquid and takes out and draw tussah, and the present invention realizes by mode down:
A kind of refinement method of silk, comprise the silk capsule the haircut deinsectization, come unstuck, steps such as refining, refining slightly, it is characterized in that
1. come unstuck, slightly refining, refinement step carry out in the alkaline solution of heat is bathed;
2. finish above-mentionedly come unstuck, slightly the silk capsule after refining, the refinement step carries out the hydrothermal solution drawing-off at least two pairs pressure roller drawing machine, described hydrothermal solution is hot bath.
3. through the silk bundle after the hydrothermal solution drawing-off, again through rare acidity neutralization bathe with remove on the tow with alkalescence.
It is characterized in that described alkaline solution comprises: the aqueous solution of sodium carbonate, potash, sodium bicarbonate, saleratus, NaOH or potassium hydroxide.
The described alkaline solution of the step that it is characterized in that coming unstuck also comprises bleeding agent in bathing.
The surfactant that also comprises soap, anion surfactant or band protease during the alkaline solution that it is characterized in that thick refining, refinement step is bathed.
It is characterized in that the silk bundle process acid bath neutralisation treatment through the hydrothermal solution drafting step, the acidity neutralization that described neutralizer is made up of acetic acid, hydrochloric acid, phosphoric acid or sulfuric acid weak solution is bathed.
1% aqueous sodium carbonate that the silk capsule that its feature also is to get 100 parts (weight) is added to 2000 parts (weight) is heated with stirring to 95 °-100 ℃ in bathing, and comes unstuck two hours, then by hand or mechanical impurity elimination; Again the silk capsule is added to the 0.5%(weight of 2000 parts (weight)) aqueous sodium carbonate bathe, be heated with stirring to 95 °-100 ℃ and came unstuck 2-3 hour, then by hand or mechanical impurity elimination; Again the silk capsule is added in the 0.5% aqueous sodium carbonate bath of 2000 parts (weight), be heated with stirring to 95 °-100 ℃, came unstuck 2-3 hour, then by hand or mechanical impurity elimination, come unstuck finish after, the alkaline water liquid melting bath that the silk capsule is put into 0.5% sodium carbonate of 2000 parts (weight) and 0.5% soap secondary repeatedly slightly refines, then the silk capsule is added to again refining in the alkaline aqueous solution of 0.25% and 0.25% soap of 2000 parts (weight), the refining number of times is to obtain 25-38 part silk bundle 1-2 time;
The above-mentioned silk bundle that obtains is carried out hydrothermal solution drawing-off growth strand by the pressure roller drawing machine more than two pairs; Again described long filament bar is cut into the rectangular of required size by cutter.
The advantage of the inventive method is that the rate of producing of preparation is up to 25-38%, the silk of gained is glossy, soft smooth, light transmission is good, draw to rub with the hands scroop sound is arranged, and fibre property excellence: the silk fiber number is the 26-34%(dry state at 0.48-0.91 between the dawn, its elongation at break), brute force is about 4.2 grams of force per Denier, and its light fastness was excellent especially, and silk still kept the brute force of 70-90% through 200 hours.Therefore, silk can partly replace natural protein fibres such as silk, sheep, and method of the present invention is " turning bane into boon ", " turning waste into wealth ", for control with utilize a bag pretty young woman insect to have positive meaning and economic benefit.
Below will be by specific embodiment, the present invention will be described in more detail.
