Embodiment 1

[0045] 1. Preparation of water-soluble polyester:

[0046] 95.8kg terephthalic acid, 12kg isophthalic acid, 15.6kg dimethyl isophthalate-5-sodium sulfonate, 8kg 1,4-cyclohexanedicarboxylic acid, 40.1kg ethylene glycol, 16.6kg new Put pentylene glycol and 50g of isopropyl titanate into the reaction kettle, replace the air with nitrogen to discharge the air, stir and raise the temperature, and react at 220-255°C. When the by-products reach the theoretical value, reduce the pressure and polymerize, the reaction temperature is 250-280 ° C, stop the reaction after reaching the end point, fill with nitrogen to eliminate the vacuum, and extrude the material.

Abstract

The invention discloses a size mixture for sizing filament. The size mixture is characterized by comprising the following components in percentage by weight: 5 to 25 percent of water soluble polyester, and 75 to 95 percent of acrylic size, wherein the viscosity of the water soluble polyester is 0.35 to 0.6. The composite can be adhered to terylene well; the adhesion and the tensile property of the size are greatly improved; the permeability of the acrylic size can be improved, and the viscosity is reduced; and by matching the water soluble polyester and the acrylic size, the performance of the size can be improved. The sizing percentage is reduced, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of textile sizing, and in particular relates to a size mixture for filament sizing, a preparation method and application. Background technique [0002] Slurries are divided into two categories: natural and synthetic. The former includes starch, modified starch, alginate, etc. The latter uses carboxymethyl cellulose (CMC), polyvinyl alcohol, polyacrylate and the like. The two can also be mixed with each other. At present, the size of the domestic filament sizing is mainly acrylic size, but the film strength of the general acrylic size is not enough, and it is prone to slack. Moreover, in terms of polyester filament sizing, its adhesion and wear resistance need to be improved. In addition, if the amount is too large, the sizing will easily cause moisture absorption and stickiness. The present invention thus comes. Contents of the invention [0003] The purpose of the present invention is to provide a si...
