Embodiment 1

[0093] The bright high-strength low-extension viscose fiber according to the present invention adopts pulp raw materials to undergo dipping, grinding, crushing, kneading, pure oxygen depolymerization, yellowing, dissolving, filtering, defoaming, maturation, spinning and drawing. It is prepared after stretching and post-treatment. After testing, the viscose fiber satisfies:

[0094] Denier 1.11D, dry breaking strength 3.10 cN / dtex, wet breaking strength 1.60cN / dtex,

[0095] The strength required to produce 5% elongation in the wet state is 0.55cN / dtex,

[0096] Dry elongation at break 13.0%, wet elongation at break 18.0%,

[0097] Crystallinity 40.0%, radial water swelling degree 22%,

[0098] Linear density deviation rate -4%, whiteness 83%,

[0099] Residual sulfur 8.0mg / 100g, length deviation rate +0.5%,

[0100] Super long fiber rate 0%, double long fiber 0mg / 100g,

[0101] Defects 0.5mg / 100g.

Embodiment 2

[0103] The difference between this embodiment and Embodiment 1 is that the pulp raw material used in this embodiment is a mixture of cotton pulp, bamboo pulp, wood pulp, and hemp pulp with a mass ratio of 3:1:1:1. After testing, the viscose fiber prepared in this embodiment meets the product characteristics of high-strength and low elongation viscose fiber.

Embodiment 3

[0105] The difference between this embodiment and Embodiment 1 is that the pulp raw material used in this embodiment is made by mixing cotton pulp and bamboo pulp with a mass ratio of 4:1. After testing, the viscose fiber prepared in this embodiment meets the product characteristics of high-strength and low elongation viscose fiber.

Abstract

The invention discloses a luminous high-strength low-elongation viscose and a production method thereof. The luminous high-strength low-elongation viscose is made by subjecting pulp material to soaking, grinding, press-crushing, rubbing, all-oxygen accumulation reducing, yellowing, dissolving, filtering, defoaming, curing, spin-drawing and post-processing; the luminous high-strength low-elongation viscose is 1.11D to 1.33D in fineness, not less than 3.10cN/dtex in dry break strength and not less than 1.60cN/dtex in wet break strength. The luminous high-strength low-elongation viscose is a novel fiber made by technical innovation, has an index system different from the common viscose and the modal fiber, has the high strength and low elongation features of the modal fiber, is higher in skin affinity than the cotton fiber and can effectively replace the existing differential viscose, downstream processability of the viscose is improved, and the development and industrial update of the downstream novel textiles can be promoted.

Description

Technical field [0001] The invention relates to a light-type high-strength low-strength viscose fiber and a preparation method thereof, and specifically relates to a variety of light-type high-strength low-strength viscose staple fiber and process control of a preparation method thereof, and belongs to the production of viscose staple fiber and cellulose fiber Innovation in the field of technology. Background technique [0002] At present, textile fiber raw materials are mainly divided into natural fiber raw materials represented by cotton and linen, petroleum-based fiber raw materials represented by polyester, acrylic, etc., and bio-based fibers such as viscose fiber regenerated from natural cellulose materials. Fiber raw materials. At present, with the scarcity of land resources and the shortage of human resources, the area of ​​cotton planting is declining year by year, and cotton products will not be able to meet the increasing needs of people’s living standards; and with th...
