Embodiment 1

[0033] A method for preparing loofah viscose fiber, which uses loofah as raw material and includes preparation, cooking, alkali refining, bleaching, washing, concentration, copying, dipping and pressing, aging, yellowing, grinding, dissolving, mixing, filtering, desiccating Foaming, filtering, spinning, drawing and post-treatment processes to obtain viscose fibers, the specific steps are:

[0034] (1) Material preparation: cut off the loofah, wash it with water, and press it to facilitate cooking and feeding.

[0035] (2) Cooking: adopt the cooking liquid to carry out in the closed steaming ball, heat up in stages, cooking aid green oxygen; The cooking liquid is calculated as NaOH, which is 15% of the relative absolute dry loofah raw material quality, and the mass ratio of solid to liquid is 1 : 2.5, the degree of vulcanization of the cooking liquid is 18%, and the cooking aid green oxygen is 0.5% of the relative absolute dry loofah mass.

[0036] The specific method is: cool...

Embodiment 2

[0054] A method for preparing loofah viscose fiber, using loofah as raw material, including preparation, cooking, alkali refining, bleaching, washing, concentration, copying, dipping and pressing, aging, yellowing, grinding, dissolving, mixing, filtering, After defoaming, filtering, spinning, drawing and post-treatment processes, viscose fibers are obtained. The specific steps are:

[0055] (1) Pre-hydrolysis of raw materials: After the loofah is cut, washed and squeezed, it is pre-hydrolyzed, the mass ratio of material to liquid is 1:3.4, and it is kept for 160 minutes after a small steam release, at a temperature of 160°C.

[0056] (2) Cooking: The cooking liquid is carried out in a closed steaming ball, and the temperature is raised in stages, and the cooking aid is green oxygen;

[0057] The cooking liquid is calculated as NaOH, which is 26% of the mass of the absolute dry loofah raw material, the mass ratio of solid to liquid is 1:3.5, the degree of vulcanization of the c...

Embodiment 3

[0074] A method for preparing loofah viscose fiber, using loofah as raw material, including preparation, cooking, alkali refining, bleaching, washing, concentration, copying, dipping and pressing, aging, yellowing, grinding, dissolving, mixing, filtering, After defoaming, filtering, spinning, drawing and post-treatment processes, viscose fibers are obtained. The specific steps are:

[0075] (1) Pre-hydrolysis of raw materials: After the loofah is cut, washed and squeezed, it is pre-hydrolyzed, the mass ratio of material to liquid is 1:3.2, and it is kept warm for 120 minutes after a small steam release, and the heat preservation temperature is 165°C.

[0076] (2) Cooking: The cooking liquid is carried out in a closed steaming ball, and the temperature is raised in stages, and the cooking aid is green oxygen;

[0077] The cooking liquid is calculated as NaOH, which is 20% of the mass of the absolute dry loofah raw material, the mass ratio of solid to liquid is 1:5.0, the degree...

Abstract

The invention discloses loofah viscose fibers and a preparation method thereof. Loofah sponge, loofah leftovers or seeded loofah is used as a raw material; and the viscose fibers with excellent performance and natural antibacterial performance are produced by the processes of material preparation, digestion, alkali refining, bleaching, washing, concentration, pulping, impregnation, squeezing, ageing, yellowing, grinding, dissolution, mixing, filtration, deaeration, filtration, spinning, drafting and post treatment. The quality index of the loofah sponge pulp fully accords with the quality requirement of pulp for the viscose fibers, the antibacterial performance of the loofah sponge is reserved, the use value of the loofah sponge is improved, the problem of raw material shortage of the conventional viscose fibers is solved, agricultural wastes can be fully utilized for producing the biomass fibers, and environmental pollution and excessive dependency on the petroleum resource are reduced.

Description

technical field [0001] The invention relates to a viscose fiber, in particular to a loofah viscose fiber and a production method thereof. The viscose fiber is produced by using loofah, loofah leftovers or seeded loofah as raw materials, and belongs to the technical field of chemical fibers. Background technique [0002] With the improvement of people's living standards and the impact of the world's energy crisis, people gradually realize the advantages of natural environmental protection materials, especially the demand for natural environmental protection materials for clothing is increasing, and the fabric can be naturally degraded after being discarded. Viscose fibers account for a considerable proportion. The main raw material that people are used to produce pulp for viscose fiber at present is hardwood, coniferous wood or cotton linters, such as patent ZL200610020980.7 (cotton, wood, hemp, bamboo composite cellulose novel pulp and its manufacturing method) disclosure A...
