Description

Powder prepared from silkworm cocoon, manufacturing method and use thereof {Powder prepared from a cocoon and the method

The present invention relates to a powder prepared from silkworm cocoons, a method for producing the same, and a use thereof.

The use of the present invention relates to functional insoles, insole surface fabrics and toothbrushes coated with silk powder on the surface.

Silk refers to fibers and their products obtained from silkworms. In other words, cocoon yarn, raw yarn, oxa, sub-jamsa, silk yarn, silk yarn, silk yarn, water spinning yarn and cotton wool and fabrics, knitted fabrics made of these raw materials are included. Silk is an animal natural fiber that is superior to cotton, wool, and chemical fiber nylon, polyester, and acrylic.

Natural silk has been widely used as a material for garments since ancient times because of its excellent affinity for living organisms and its own softness. In addition, since silk is composed of fibroin, which is a protein component, silk has been studied for its various uses, such as extracting amino acids important to the human body and using them as health foods. Therefore, various methods have been studied for powdering silk from cocoon and using it for health food or clothing products and new biomaterials.

Conventional powders were obtained by removing yarns from silkworms and then pulverizing the yarns in a dry or wet manner. Here, the dry method is to powder the silk fibroin by mechanical grinding means, to obtain a powder by grinding through a two-step process consisting of a first process and a second process, in order to obtain a fine powder of 10 ㎛ or less Go through the third process. In the wet method, the yarn is dissolved in an organic solvent or a salt and then dried and powdered.

Due to the classification according to the cocoon screening criteria, a large quantity of cocoons with poor quality are disposed of and disposed of, and a lot of losses and processing costs are required.

So far, E.V.A and PVC have been used as insoles for shoes, and PS and PA have been used as toothbrush handles, and polymer single products or the same synthetic materials were mixed for various purposes. For example, it was used for the purpose of providing color, gloss, processability, design, texture, and the like to the product. However, products made from these materials did not actively respond to consumer tastes. Basically, slippery sensation in direct contact with human skin, eye fatigue due to reflected light, and poor absorption of sweat caused harm to health directly and indirectly.

In order to solve the above problems, the present invention provides a silk fine powder prepared directly from the cocoon to reduce the inconvenience and economic burden of the method for obtaining the silk fine powder from the conventional fiber and also to powder directly from the cocoon To provide a powder prepared from silkworm cocoons which have been enhanced in functionality by coating silk powder on a shoe insole or a toothbrush handle based on the method of obtaining and the excellent sweat absorption and breathability of silk, and a method and a use thereof. It is to be done.

In order to achieve the above object, a feature of the present invention is not only silkworm cocoon, but also silkworm which is judged to be unsuitable and the silkworm cocoon of poor quality through a simple process to crush silk by direct grinding. The present invention relates to a powder prepared from silkworm cocoons which are powdered and used for the handle of a shoe insole or a toothbrush, a manufacturing method and a use thereof.

In the powdering process, the pulverization is very advantageous in terms of cost because it does not incur double costs because it directly pulverizes the cocoon as compared with the powdering using conventional silk or waste silk. It is also useful for the treatment of waste cocoons because they use poor quality cocoons as well as regular cocoons.

Silk is chemically a natural protein, and the main components of this protein, which are secreted from the silk glands of silkworms that spew thread, are composed of fibroin and sericin. One cocoon consists of about 1,000 to 1,300 meters of elongated fibers. The silkworm vomiting cocoon consists of two strands of fibroin and sericin, and the sericin forms a cocoon covering two strands of fibroin. The double structure of fibroin and sericin is characteristic of silk that is not found in other natural fibers, and sericin is dissolved and removed during processing into fabrics.

Fibroin of keratin or silk fiber, which is a major component of wool, is a condensate of various amino acids by polypeptide binding as one protein, and thus is a positive compound having amino base (-NH₂) and carboxyl base (-COOH) in its molecular structure. .

The present invention is used as insoles and insoles fabricated by finely crushing the silk powder containing silk powder or waste silk and coated on the existing insole material EVA or PVC, or coated on a polymer film and attached to a mobile phone or mouse will be

The present invention will be described in detail with reference to the following Examples.

Example 1
