Abstract

The invention discloses a production method for ultrafine raw silks of 7 / 9D specifications. The method includes: processing high-quality ultrafine-denier cocoons with the fineness of 1 denier by hot air at the low temperature, drying the cocoons to dried cocoons by a dry method, cooking the dried cocoons for a short time at the low temperature to appropriately-cooked cocoons by the aid of steam and a cocoon cooking method, and reeling with 8 fixed cocoons by a small-aperture ceramic eyelet at a low speed to produce the ultrafine raw silks of the 7 / 9D specifications. The produced ultrafine raw silks of the 7 / 9D specifications are small in denier deviation and high in cleanliness, and a novel product woven by the raw silks is unique in gloss and flavor, crease-resistant, capable of improving dyeing property greatly and good in social and economic benefits. In addition, the traditional sericulture can be improved, and diversified demands of domestic and foreign markets can be met.

Description

technical field [0001] The invention relates to a production method of raw silk, in particular to a production method of 7 / 9D superfine raw silk. Background technique [0002] Raw silk is a product made by embracing several silkworm cocoons through silk reeling. It has the characteristics of softness, smoothness, fullness, good elongation, elasticity, soft luster, strong hygroscopicity, and no irritation to the human body. High-grade textile materials can be used to weave all kinds of silk fabrics for clothing, interior products, handicrafts, decorations, etc. Traditional raw silk has specifications such as 20 / 22D, 27 / 29D, 28 / 30D, 34 / 36D, 40 / 44D, etc. It has poor wrinkle resistance and cannot weave ultra-thin flavored silk and its products. To the desired effect, it is also not suitable for fields such as special thorn rust wire, which does not meet the diversified needs of today's society. [0003] The fabric woven from fine denier raw silk has the characteristics of stro...
