Problems solved by technology

Acrylic size polymethyl acrylate and polyacrylamide both have serious re-adhesion phenomenon, because: the synthesized size contains too many hydrophilic groups, and the strong water absorption makes the dried size film easy to absorb moisture and partially It dissolves and has a certain viscosity, so it is easy to have insufficient moisture absorption and stickiness on the loom, thus affecting the weaving effect

Embodiment Construction

[0007] The present invention will be further described in detail below in combination with specific embodiments.

[0008] The acrylic size is characterized in that it includes the following components in weight percentage: 20-30% modified starch, 20-40% chitosan, 30-60% methyl acrylate.

[0009] The weights of the components used in Examples 1-4 are shown in Table 1 (in kg)

[0010] Example 1 Example 2 Example 3 Example 4 modified starch 20.3 23.5 29.9 26.5 Chitosan 23.0 27.5 39.1 40.1 Methyl acrylate 30.5 42.6 60.0 51.2

[0011] Adopt the size of embodiment 1 to test T / C 65 / 35 13 / 13 345 / 236 kind on the sizing machine, the sizing rate is 12.5%, the solid content rate is 7.6%, the moisture regain is 2.3%, and the viscosity is 5.3% , the enhancement rate was 16.8%, and the elongation reduction rate was 23.9%. In addition, it can be seen from the slices of the sizing machine that the size liquid penetrates well, the size film is ...

Abstract

The invention relates to an acrylic size which is characterized by comprising the following components in percentages by weight: 20-30% of modified starch, 20-40% of chitosan and 30-60% of methyl acrylate. A large number of amino groups is contained in the molecular formula of the chitosan and can be combined with the hydroxyl on the methyl acrylate group to neutralize a part of hydrophilic groups, therefore, the water absorption is properly reduced, and the moisture absorption and viscosity properties are reduced.

Description

technical field [0001] The invention relates to a slurry and belongs to the field of textile chemistry. Background technique [0002] Warp yarn sizing can increase wear resistance and fit hairiness, and can also enhance and maintain elongation for fine-sized yarns. When weaving with air-jet looms, the effect of fit hairiness is more prominent. The main components of the current size are modified starch, PVA and acrylic paste. Acrylic size polymethyl acrylate and polyacrylamide both have serious re-adhesion phenomenon, because: the synthesized size contains too many hydrophilic groups, and the strong water absorption makes the dried size film easy to absorb moisture and partially It dissolves and has a certain viscosity, so it is easy to have insufficient moisture absorption and re-adhesion on the loom, thus affecting the weaving effect. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a biodegradable cotton fiber slurry...
