Problems solved by technology

Although the regularity of the PVA molecular chain is high, the film performance is good, and the production efficiency can be improved, it is difficult to desizing, it is not easy to completely desizing, and it is difficult to biodegrade. After desizing, it becomes a recognized environmental pollution substance. Hydroxypropyl Starch is the most commonly used size in sizing production. It has abundant sources, relatively low price, is environmentally friendly, and is easily degraded by microorganisms. It can be desized by biological enzymes, and the desizing waste liquid has little impact on the environment.
However, its hard and brittle serous film has poor adhesion to polyester fibers, which seriously affects its use effect.

Embodiment 1

[0013] According to mass ratio:

[0014] Methyl benzoate 30%;

[0015] Hydroxypropyl starch 30%;

[0016] Carboxymethylcellulose 40%.

Embodiment 2

[0018] According to mass ratio:

[0019] Methyl benzoate 50%;

[0020] Hydroxypropyl starch 40%;

[0021] Carboxymethylcellulose 10%.

[0022] The inhomogeneous phase structure of methyl benzoate is used to toughen the size film, improve the impact resistance and bending fatigue resistance of the size film, and reduce slumping. Secondly, reduce the pollution of desizing wastewater to the ecological environment.

Abstract

The invention discloses a slurry for sizing of polyester fiber and belongs to the technical field of textile polyester fiber sizing slurries. The slurry comprises the following components: 30-50 percent of methyl benzoate, 30-40 percent of hydroxypropyl starch and 10-40 percent of water-soluble cellulose ether. The water-soluble cellulose ether is carboxymethylcellulose. The slurry has the beneficial effect of reducing the pollution of de-sizing wastewater to ecological environment.

Description

technical field [0001] The invention relates to a polyester fiber sizing slurry, which is a starch-based compound containing a methyl benzoate component, and belongs to the technical field of the slurry used for textile polyester fiber sizing. Background technique [0002] At present, the size used for sizing containing polyester fibers is mainly polyvinyl alcohol (PVA) size. Although the regularity of the PVA molecular chain is high, the film performance is good, and the production efficiency can be improved, it is difficult to desizing, it is not easy to completely desizing, and it is difficult to biodegrade. After desizing, it becomes a recognized environmental pollution substance. Hydroxypropyl Starch is the most commonly used size in sizing production. It has abundant sources, relatively low price, is environmentally friendly, and is easily degraded by microorganisms. It can be desized by biological enzymes, and the desizing waste liquid has little impact on the environ...
