Problems solved by technology

Although the fineness of the silk produced by these two methods is nearly 1 / 3 smaller than that of the traditional (tetrasomnous cocoon) silk, its properties still cannot meet the needs of special purposes.

Embodiment 1

[0018] After dissolving the "superfine element" medicinal powder with hot clean water, dilute it with cold clean water to 1250 times of liquid medicine. According to the weight ratio of medicinal liquid: mulberry leaves being 1:5, the medicinal liquid is evenly sprayed on the mulberry leaves until it is fully sprayed evenly. After the medicinal liquid on the mulberry leaves dries up slightly, feed them to Baiyu×Qiufeng 4th-instar silkworms raised in a clean environment of 25-28°C with suitable ripe mulberry leaves, and the feeding time is continuous at 25-28°C 24 hours. Continue to use normal ripe mulberry leaves to raise them in a clean environment at 24-25°C. After 10 days, the silkworms mature, and the three-drowning induction rate of silkworms is 100%. Use a 2.8cm×4.3cm square grid or a wave crest distance of 4.5-5cm and a peak height of 5.5-6.0cm to fold the cocoon on the cocoon. The environment in the box is kept at a temperature of 23-25°C, a humidity of 70-75%, and un...

Embodiment 2

[0020] After dissolving the "superfine element" medicinal powder with hot clean water, dilute it with cold clean water to make a 2500 times liquid medicine. According to the weight ratio of medicinal liquid: mulberry leaves being 1:5, the medicinal liquid is evenly sprayed on the mulberry leaves until it is fully sprayed evenly. After the medicinal liquid on the mulberry leaves dries up slightly, feed them to Baiyu×Qiufeng 4th-instar silkworms raised in a clean environment of 25-28°C with suitable ripe mulberry leaves, and the feeding time is continuous at 25-28°C 48 hours. Continue to use normal ripe mulberry leaves to raise them in a clean environment at 24-25°C. After 9 days, the silkworms mature, and the three-dormant induction rate of silkworms is 100%. Use a 2.8cm×4.3cm square grid or a wave crest distance of 4.5-5cm and a peak height of 5.5-6.0cm to fold the cocoon on the cocoon. The environment in the box is kept at a temperature of 23-25°C, a humidity of 70-75%, and ...

Embodiment 3

[0022] After dissolving the "superfine element" medicinal powder with hot clean water, dilute it with cold clean water to make a 2500 times liquid medicine. According to the weight ratio of medicinal liquid: mulberry leaves being 1:5, the medicinal liquid is evenly sprayed on the mulberry leaves until it is fully sprayed evenly. After the medicinal liquid on the mulberry leaves dries up slightly, feed them to Xinhang×Baiyun 4th instar silkworms raised in a clean environment of 25-28°C with suitable ripe mulberry leaves, and the time of feeding the medicinal leaves is continuous at 25-28°C 48 hours. Continue to use normal ripe mulberry leaves to raise them in a clean environment at 24-25°C. After 9 days, the silkworms mature, and the three-dormant induction rate of silkworms is 100%. Use a 2.8cm × 4.3cm square grid or a wave crest distance of 4.5-5cm and a peak height of 5.5-6.0cm to fold the cocoon on the cocoon. The environment in the box is kept at a temperature of 23-25°C,...

Abstract

Method for preparing fine silk thread is characterized by inducing tetramolter with superfine agent to tri-molt to produce tetramolter silk, wherein the single yarn fineness is 1 Denier. It has better colored, refraction, and crease-resisting property than tetramolter silk, it has small fibre finess deviation, high lustration, low cost, products made by such silk have improved luster and chromaticity.

Description

technical field [0001] The invention relates to a production method of superfine silk. Background technique [0002] Silk is the strands spit out by the silkworm (Bombyx mori L.) during cocooning. It has the characteristics of slenderness, toughness, softness, ventilation, moisture absorption, elasticity, good luster, and strong dyeing. It is an important textile raw material and can be used to weave beautiful Excellent silk and luxurious clothing and handicrafts enjoy a high reputation at home and abroad. The fineness of traditional (four-sleeping silkworm cocoon) silk is 2.6-3.0 denier (Denier), and its anti-wrinkle performance is poor. It cannot weave ultra-thin silk and its products with flavor, and it cannot achieve the ideal effect when used in the production of core silk. , It is also not suitable for fields such as special thorn rust wire, which does not meet the diversified needs of today's society. [0003] In order to meet the diverse needs of the society for si...
