Description

[Detailed description of the invention] Fibers whose specific heat and electric charge are very similar to those of the human body and which have good adsorption of pigments are materials for clothes that are elegant and have a pleasant feel, but they also have a history of being stain-resistant and easy to wash. When this happens, it becomes a garment of great value.

The two fibers of fibroin that are produced by the silk thread of the silkworm are made sticky with each other and then spit out, making up about 20 to 30% of the raw silk.
The purpose of the present invention is to transform sericin, which occupies the majority of silk, into a complex structure, and to make it into spheres that can be used practically as an everyday base material by taking its time as the outer layer of silk.

Fibroin fibers are relatively smooth long fibers with a nearly triangular cross section. The elongation is about 20%, which is weaker than cotton wool, nylon, etc. Although its disadvantage is that it has poor sunlight resistance, it has a length M that is strong against impacts.

Although sericin is flexible when swollen, it has the disadvantage of being irritating to water.

Therefore, old rice was pounded with stones, etc., and by scouring, the rice was softened and made into beautiful silk fabrics.

Shintoshi washes sericin through scouring and uses it as a flexible silk fabric, but the demand for it has been limited because it gets dirty easily and is difficult to wash.

Therefore, covering silk with a film makes it difficult to get wet. Sericin itself does not change, but it has the property that its properties change when its structure changes, and it becomes resistant to staining even after drying, making it easier to carry around. Furthermore, it is resistant to sunlight. It dries easily even if you dry it in the shade, and you can use a dehydrator, so it won't turn yellow, and even if you don't use detergent, if you shock it in the water, the dirt will come off, so there will be no soap left on the cloth, which can cause browning due to free fatty acids.

The gaps between sericin molecules contain air or water, which acts like a terminal and maintains the properties of raw silk, but its properties can be changed by making it more complex.

In order to change sericin into a complex structure, there is a method of combining cocoon fibers with a substance with a complex structure, such as a solution of Shibu (shibu), which allows several molecules of condensation to form under specific conditions at a certain temperature and for a certain period of time. It becomes a polymerized compound and can maintain its role as the outer layer of fibroin.

It becomes stronger and has a good effect on the weaving process as a fiber with threadability.

The traditional impression that silk is weak against water has been changed to the impression that it can withstand water, and now silk is resistant to impact and has a beautiful luster, while maintaining its outstanding characteristics that are comparable to other natural fibers. *The point is that it will grow worldwide - Togu←Prickly Needle -'l
I screamed.

An example of implementing the present invention is as follows.

The cocoon layer is infiltrated with a solution of around 10% Oki Shibu, and the cocoon fibers, which have complex properties, are drawn from the reeling tank and conjugated to make raw silk.

Claims (1)

[Claims] A method of making silk into raw silk for textiles that does not easily get wet, which is characterized by modifying cocoon fibers with a Shibu (astringent) solution so as not to stain the outer layer.
