Embodiment 1

[0024] Aiming at the defects in the prior art, the invention provides a method for adding a viscose dissolving aid, first adding the dissolving aid into the dissolving lye, dissolving and mixing, and then adding the dissolving lye mixed with the dissolving aid into the fiber Sulfonate is dissolved.

[0025] A method for adding a viscose dissolving aid, specifically comprising the steps of:

[0026] (1) Deployment of dissolved lye mixed with dissolution aids: inject desalted water, caustic soda and dissolution aids into the dissolved soda tank respectively. The liquid level is interlocked; the dissolution aid is injected into the dissolving alkali barrel through the peristaltic pump, and the peristaltic pump and the regulating valve of the caustic soda are opened and closed in interlocking; the demineralized water refers to pure water that does not contain salt. The opening and closing chain is the opening and closing chain of the peristaltic pump opening and stopping and the ...

Abstract

The invention discloses an adhesive dissolving auxiliary agent adding method. The method comprises the following steps: at first, adding a dissolution auxiliary agent into a dissolving liquid alkali, mixing to dissolve the auxiliary agent, and then adding the dissolving liquid alkali containing the dissolution auxiliary agent into cellulose sulfonate to dissolve cellulose sulfonate. Because the viscosity of dissolving liquid alkali is low, dissolution auxiliary agent is quickly dissolved into the dissolving liquid alkali. The dissolving liquid alkali is mixed during the blending process, and the dissolution auxiliary agent is evenly dispersed into the dissolving liquid alkali, so the dissolution of cellulose sulfonate becomes easier.

Description

technical field [0001] The invention relates to the technical field of viscose fiber production, in particular to a method for adding a viscose dissolving aid. Background technique [0002] Viscose fiber is the full name of viscose fiber, which is divided into viscose filament and viscose staple fiber. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Its moisture content is most in line with the physiological requirements of human skin, and it has the characteristics of smooth and cool, breathable, antistatic, and brilliant dyeing. In the production of viscose fiber, in the viscose solution preparation process, it is necessary to add a dissolution aid that is conducive to the dissolution of cellulose sulfonate. This aid needs to be uniformly and dispersedly added to the viscose solution. Adding 1 / 10,000 to 5 / 100,000 to order and uniformity is an important factor restricting the performance of additives. [0003] The existing additives are a...
