Problems solved by technology

Since PVA is a typical refractory biodegradable polymer substance, its wastewater has high COD and poor degradability, and direct discharge will seriously pollute the water body
[0003] In order to improve the degradability of the slurry, CMC (sodium carboxymethyl cellulose) is used as the slurry of continuous spun viscose filaments, but the CMC film-forming strength is low, and the cohesion of the viscose filaments after oiling is poor, so it cannot Meet the production needs of multiple varieties of products
There is also a method of using high-performance starch size, but the film-forming strength of this type of size cannot meet the production requirements of continuous spun viscose filaments

Abstract

The invention discloses a novel continuous spinning viscose filament yarn treating agent as well as a preparation method and application thereof. The treating agent comprises the following components in parts by mass: 10-50 parts of a nonionic surfactant; 5 to 20 parts of an anionic surfactant; 10 to 60 parts of a bundling agent; 0.2 to 2 parts of an antioxidant; 0.2 to 1 part of a bactericide; and 20 to 80 parts of deionized water. The prepared treating agent has excellent water solubility, viscosity stability, film-forming property, desizing property and degradability. The viscose filament yarn treated by the treating agent has good cohesive property, the bifurcation phenomenon cannot occur between parallel filaments, and no particulate matter exists on the surface of the filaments. In the downstream refining process, the viscose fibers are easy to desize and free of residues, follow-up dyeing cannot be affected, and waste can be degraded.

Description

technical field [0001] The invention relates to the field of chemical auxiliaries, in particular to a novel continuous spun viscose filament treatment agent and a treatment method. Background technique [0002] In the production process of viscose fiber, continuous spun viscose filaments are parallel filaments without twisting. It is necessary to attach oil and slurry on the surface of viscose filaments to give fibers cohesion, smoothness, and antistatic properties. Continuous spun viscose filaments have higher requirements for cohesion, and PVA (polyvinyl alcohol) has excellent film-forming properties and is often used as a slurry. However, in the downstream textile process, the oil and size of the viscose fibers need to be removed. Since PVA is a typical refractory biodegradable polymer substance, its wastewater has high COD and poor degradability, and direct discharge will seriously pollute the water body. [0003] In order to improve the degradability of the pulp, CMC ...
