Developed and provided is a method by which bagworm silk is collected from a bagworm nest easily, in large amounts, and at a low cost, such silk not containing impurities and being of high quality. Byutilizing the behavior of bagworms, only the pure bagworm silk forming a bagworm nest can be obtained by causing the bagworms to build a nest with a nest material of a solvent soluble material and aneasily-heat-soluble material, dissolving or melting the nest material, and separating the nest material and the bagworm silk.

Disclosed are a dental barrier membrane for guided bone regeneration using a silk matrix and a method of manufacturing the same, wherein the dental barrier membrane is configured such that a silk matrix having a cross-section with a first thickness, produced from silkworms, is subjected to planar division into two or more silk matrix pieces having a predetermined shape with the first thickness. This dental barrier membrane is biocompatible, has superior tensile strength and porosity, and promotes the formation of new bone in bone defects, unlike existing dental barrier membranes.

The invention discloses a processing method of silk tops. The processing method comprises the following steps: (1) finishing raw materials; (2) selecting and checking; (3) combining into consuming refined products; (4) opening cocoons; (5) performing ultraviolet irradiation; (6) performing medium biling; and (7) performing circular carding processing. The silk tops processed by utilizing the processing method have the characteristics of being good in quality and reasonable in cost.

This invention relates to hollow pulp cocoon, dried cocoon and live cocoon filature process, which vacuums the waste hollow pulp cocoon or dried cocoon discarded in traditional process and dips the cocoon under room temperature after being boiled and goes through dispel liquid composed of sodium silicate, sodium carbonate, red oil, borax, hydrogen dioxide solution, surface activity agent and water and finally through filature and shading and processing into silk.

A method of producing a transgenic silkworm that spins bagworm silks and producing a large quantity of bagworm silks by transgenic technology is developed and provided. A gene encoding a modified bagworm Fib H and a transgenic silkworm in which the gene is introduced, wherein the gene is obtained by cloning a gene fragment encoding a bagworm Fib H-like polypeptide comprising a partial amino acid sequence of bagworm Fib H, and fusing the gene fragment to a gene fragment encoding silkworm-derived Fib H, are provided.

The invention relates to a silk cotton machine for manufacturing silk cotton. The machine comprises a frame, a transmission device, a roller, a material groove, a water spray pipe, an upper baffle plate, a lower baffle plate and a scraping knife, wherein an arc-shaped fling-proof plate, an arc-shaped silk pasting plate and a fling-proof chrysalis-removing plate are arranged on the periphery of the roller. Due to the action of the arc-shaped silk pasting plate, silk after passing through the scraping knife can be closely attached on the outer surface of the roller; furthermore, once the silk attached on the roller is flung away from the roller, due to the blocking effects of the arc-shaped fling-proof plate and the fling-proof chrysalis-removing plate, the silk which is flung away can be rapidly returned onto the roller and be prevented from entangling and shedding, and the quality and the finished product rate of the machine processed silk cotton can be further improved; simultaneously, the diameter of the roller of the silk cotton machine can be increased so as to facilitate the manufacturing of an extra-width breadth silk cotton quilt with good uniformity, thereby solving the non-uniformity caused by splicing and the increased process steps during the traditional manufacturing of the extra-width breadth silk cotton quilt.

The purpose of the present invention is to develop and provide a method for thread collection with which it is possible to easily and simply collect pure silken thread originating with bag worms fromthe bag worms, and a thread collection device for implementing that thread collection method. Provided is a device for collecting silken threads from bag worms that is provided with a container for accommodating a bag worm and an entrance and exit hole for removing and inserting a bag worm into that container and wherein the width of the maximum short axis cross section in the inside space of thecontainer is in a range of greater than or equal to 1.2 times and less than 3.1 times the maximum width of a bag worm to be accommodated therein.
