Embodiment 1
[0093] The bright high-strength and low-elongation viscose fiber involved in the present invention is made of pulp raw materials, which are sequentially impregnated, ground, crushed, kneaded, depolymerized with pure oxygen, yellowed, dissolved, filtered, defoamed, matured, and drawn by spinning. After stretching and post-treatment, the viscose fiber meets the requirements of:
[0100] Super long fiber rate 0%, double long fiber 0mg / 100g,
[0101] Defect 0.5mg / 100g.
Embodiment 2
[0103] The difference between this example and Example 1 is that the pulp raw material used in this example 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 by this embodiment meets the product characteristics of high-strength and low-elongation viscose fiber.
Embodiment 3
[0105] The difference between this example and Example 1 is that the pulp raw material used in this example is a mixture of cotton pulp and bamboo pulp with a mass ratio of 4:1. After testing, the viscose fiber prepared by this embodiment meets the product characteristics of high-strength and low-elongation viscose fiber.

Abstract
The invention discloses a superfine viscose fiber and a preparation method thereof. The superfine viscose fiber is prepared by using a pulp material sequentially through impregnation, grinding, pressing and crushing, kneading, pure oxygen reduced polymerization, xanthation, dissolution, filtration, defoaming, ripening, spinning and drawing and post-treatment. The viscose fiber satisfies conditions that the fineness is 0.88 to 1.11D, the dry fracture strength is higher than or equal to 3.20cN / dtex and the wet fracture strength is higher than or equal to 1.60cN / dtex. The high-tenacity low-elongation viscose fiber disclosed by the invention is a novel fiber type realized through technical innovation and has an indicator system different from common viscose fibers and modal fibers, products made by the viscose fibers not only reflect fiber characteristics of high tenacity and low elongation of modal fibers, but also reflect better skin adaptability than cotton fibers, can effectively replace the existing differential viscose fibers and can promote the development and industrial upgrade of downstream novel textiles on the premise of improving the downstream processing performance of the viscose fibers.
Description
technical field [0001] The invention relates to the field of superfine viscose fiber and its preparation method, in particular to the process control of superfine viscose staple fiber and its preparation method, and belongs to the innovation in the technical field of viscose staple fiber and cellulose fiber production. Background technique [0002] At present, textile fiber raw materials are mainly divided into natural fiber raw materials represented by cotton, hemp, etc., petroleum-based fiber raw materials represented by polyester, acrylic fiber, etc., and bio-based raw materials such as viscose fiber regenerated from natural cellulose materials. Fiber raw material. At present, with the scarcity of land resources and the shortage of human resources, the cotton planting area is declining year by year, and cotton products will not be able to meet the growing needs of people's living standards; With the increasing awareness of functionality and environmental protection, more...
