Embodiment 1

[0027] Regarding the processing technology of the existing waste viscose, we know that after the waste viscose is collected and processed, it is usually reused in the production of viscose short filaments. The existing patent document CN102586954A discloses such a treatment method, which will The waste viscose is collected and processed and then reused in the yellowing machine used in the production of viscose staple yarn, as the raw material for the production of viscose staple yarn. While realizing the production of viscose, it also has the advantages of saving production costs and reducing environmental pollution Index and the production characteristics of improving economic benefits, but for the existing technology, we found that in the known public technology, waste rubber is not directly added to normal viscose, and used for the production of viscose filaments in large production systems, Therefore, for the diversity of waste viscose processing and further reducing the en...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is: in this embodiment, the maturity degree of the waste rubber in the waste rubber collection tank is controlled at 8.8, and the viscose particle content of the waste rubber is controlled at 1000 / ml.

Embodiment 3

[0035] The difference between this embodiment and Embodiment 1 is that the filter involved in this embodiment is a plate and frame filter, wherein the filter cloth of the plate and frame filter consists of two layers of poplin, two layers of plain cloth and one The waste glue sent to the plate and frame filter is filtered through two layers of poplin, two layers of plain cloth and one layer of double fleece in sequence. After filtering, the number of viscose particles in the waste glue is 200 pieces / ml, a viscosity of 38Pa·s, and a maturity of 9.8.

Abstract

The invention discloses a recycling process of waste viscose. The waste viscose obtained through collection is fed into the viscose filament production process after filtration, defoaming and ripening, wherein the waste viscose is dismantling waste viscose of a filter in a viscose production system. According to the recycling process of the waste viscose, the technical problem that the waste viscose cannot be recycled to continue to be applied to the viscose filament production in the existing waste viscose recycling scheme is solved, the waste viscose cannot be directly added into normal viscose after the filtration treatment and can enter the large viscose production system to be applied to the viscose filament production, the economic benefit is obvious in comparison with the way that the waste viscose is applied to viscose staple production, meanwhile the environment-friendly pressure can be reduced, and the viscose production efficiency can be improved.

Description

technical field [0001] The invention relates to a recovery process of waste viscose, specifically relates to the recovery and utilization of waste viscose in the viscose production process, and belongs to the field of viscose production. Background technique [0002] Viscose is made by impregnating a certain amount of pulp in alkali, pressing to remove excess alkali liquid and crushing to form loose flocculent alkali cellulose, and then reacting with carbon disulfide to form cellulose sulfonate, the cellulose sulfonate Viscose can be made by evenly dissolving in dilute lye, and viscose that is qualified and meets spinning requirements can be produced after the viscose obtained is filtered, defoamed, matured and other processes. Among them, the filtering process of viscose is to use a plate and frame filter to remove various solid or semi-molten particles in the viscose, so as to avoid spinning difficulties or decrease in fiber product quality due to clogging of the spinneret...
