Problems solved by technology

However, the thickness of the cocoon layer of the male and female silkworm cocoons of the same species is different, and the size of the pupal body is different. Therefore, it is difficult to prepare high-grade and high-grade raw silk by using the conventional silk reeling process of mixed male and female silkworms.
[0004] For the existing fluorescent cocoon silkworm varieties, the conventional mixed drying, boiling, and mixed silk reeling processes are still used, only male and female composite silk can be reeled, and mass production of 6A-grade raw silk cannot be achieved

Embodiment 1

[0016] Select an ultraviolet light source lamp with an emission wavelength of 300 to 380 nanometers and an ultraviolet light-transmitting glass in this wavelength range to form a simple fluorescent detection device for male and female cocoons of silkworms. According to the characteristics of the silkworm cocoon: female cocoon purple fluorescence, male cocoon white fluorescence or female cocoon white fluorescence, male cocoon yellow fluorescence or female cocoon purple fluorescence, male cocoon yellow fluorescence, perform fluorescence judgment, and separate female and male cocoons .

[0017] The size and thickness of the cocoon layer of the female and male silkworm cocoons were measured respectively. Referring to the conventional cocoon drying process, the cocoon drying process conditions were adjusted as follows: when drying the female cocoons, reduce the constant-speed drying temperature by 3-10°C, and shorten the deceleration drying time by 0.5°C. ~3.5 hours; for male cocoo...

Abstract

The present invention discloses a process for preparing high-quality gender cocoon fibre. Said process comprises the following steps: adopting breeded fluorescent cocoon color to judge breed variety of gender silkworm under ultraviolet light source, respectively measuring sizes of female / male silkworm cocoon and thickness of cocoon layer after separating female silkworm cocoon from male silkworm cocoon, adjusting the cocoon drying technological conditions according to determination of conventional technological condition for cocoon drying and cocoon boiling, wherein for female cocoon, the reducing dry temperature is adjusted to 3-10 DEG C and the shortening reduced speed dry time is adjusted to 0.5-.5 hours, for male cocoon, the prolonging reduced speed dry time is adjusted to 0.5-.5 hours; regulating the technological conditions for cocoon boiling, for female cocoon, the prolonging boiling setting time is 1-3 minutes, for male cocoon, the shortening boiling debug time is 1-3 minutes; then, reeling silks at an auto cocoon cooking machine or an auto fiber-fixed reeling machine to manufacture male silkworm bast silk with a gradation of 6A and female silkworm bast silk with a gradation of 5A-6A. The obtained bast silks is one or two gradations higher than the male / female mixing bast silk, and then realizes the batch silk reeling of cocoon fibre, with high quality.

Description

technical field [0001] The invention relates to a drying and reeling process of silkworm cocoons, in particular to a method for preparing high-quality gendered silk, which belongs to the technical field of silk production in textile engineering. Background technique [0002] At present, the cocoons of conventional current silkworm varieties are mixed with male and female cocoons, and the cocoon cooking process is based on factors such as differences between silkworm varieties, differences between breeding seasons, cocoon size and cocoon layer thickness, etc., with reference to certain experience, such as Determined by the "Cocoon Harvesting and Drying Business Manual" (Jiangsu Silk Import and Export Corporation, April 1994), it is generally believed that in the conventional cocoon drying and cocoon boiling process conditions, constant drying temperature, deceleration drying time and cooking Adjustment time is a relatively critical link, and the dete...
