Problems solved by technology

However, the removal operation requires enormous effort and cost, so as a result, the production cost becomes high
In addition, it is difficult to completely remove impurities by the conventional technology, and the final product is also mixed with very few leaflets, etc., and the silk is dyed light brown due to pigments derived from impurities, etc., which is a low-quality product.

Embodiment 1

[0107]

[0108] (Purpose)

[0109] It was verified that using the silk picking device of the present invention, it is possible to easily and simply collect a block of silk that does not contain impurities and is composed of pure bag moth larvae silk.

[0110] (method)

[0111] As the bag moth larvae, the last instar larvae of the bag moth collected in the field in November were used. The maximum body width of each individual is in the range of 9.0 mm to 10.0 mm, and the total length is in the range of 30.0 mm to 32.0 mm.

[0112] A 10 mL polypropylene conical tube (Iwaki Corporation) was used as the container of the silk picking device. The width (inner diameter) of the maximum short-axis section of the internal space of this container was 14.5 mm, and the length was 97.0 mm. In this case, the tube opening corresponds to the container access hole. In addition, a test tube rack was used as the fixing part.

[0113] After the bag moth larvae were taken out from the nest u...

Embodiment 2

[0116]

[0117] (Purpose)

[0118] It was verified that the silk picking device of the present invention equipped with a discharge hole can collect a block of silk silk without impurities from an active bag moth larvae.

[0119] (method and results)

[0120] As the bag moth larvae, 10 sub-to-last instar larvae of the tea bag moth collected in the field in June were used. The maximum body width of each individual ranged from 6.0 mm to 8.0 mm, and the total length ranged from 24.0 mm to 30.0 mm.

[0121] A polypropylene 10 mL pipette tip (Pipette tip, Eppendorf) was used as the container of the silk picking device for verification. The width (diameter) of the maximum short-axis cross-section of the inner space of this container was 13.5 mm. Furthermore, in the case of a pipette tip, the pipette connection port corresponds to the container access hole. On the other hand, the bottom of the tube (tip tip) was cut to create a discharge hole with a diameter of 3.5 mm. A 10-mL ...

Embodiment 3

[0123]

[0124] (Purpose)

[0125] The relationship between the ratio of the maximum short-axis cross-section width of the container inner space of the silk picking device to the maximum body width of the housed bag moth larvae and the formation of silk lumps was verified.

[0126] (method)

[0127] As the bag moth larvae, the last instar larvae of tea bag moth larvae collected in the field in June with a total length of 30 mm and a maximum body width of 7 mm were used.

[0128] The width (diameter) of the largest short-axis section of the inner space of the container in the silk picking device is 9 mm (2.5 mL pipette tip made of polypropylene, φ9 mm × height 115 mm: Eppendolf), 12.0 mm (6 mL glass test tube, φ12mm × height 75mm: As one), 15.0mm (15mL glass test tube, φ15mm × height 85mm: As one), 22.0mm (50mL glass test tube, φ22mm × height 200mm: As one), 30.0mm (50mL Conical tube made of polypropylene, φ30mm x height 118mm: As one company), 120mm (cylindrical plastic co...

Abstract

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.

Description

technical field [0001] The present invention relates to a device for collecting silk derived from larvae of moths belonging to the family Psychidae (Psychidae), that is, silk silk from Psychidae larvae (hereinafter, in this specification, often expressed as "silk picking device"), and using the A method of collecting high-purity spun silk derived from bag moth larvae with a silk device. Background technique [0002] Silk constituting the cocoons of insects and hair of mammals have been used as animal fibers for clothing and the like since ancient times. In particular, silkworm silk (in this specification, often expressed as "silk silk") derived from silkworm (Bombyx mori) larvae is excellent in moisture absorption and desorption, moisture retention, and heat retention, and has a unique luster. and smooth skin feel, so it is valued as a high-quality natural material even now. [0003] However, in nature, there are animal fibers that are comparable to silk silk or have prope...
