Problems solved by technology

[0002] Methyl acrylate size, polymethyl acrylate and polyacrylamide all have serious re-adhesion phenomenon. One of the reasons is that: the synthetic size contains too many hydrophilic groups, and the strong water absorption makes the dried size The film is easy to absorb moisture and partially dissolve, and has a certain viscosity, so it is easy to have insufficient moisture absorption and stickiness on the loom, thus affecting the weaving effect
Another reason is that the vitrification temperature of the synthetic slurry is too low, and it shows a high elasticity that is easy to deform in the temper

Embodiment Construction

[0008] The present invention will be further described in detail below in combination with specific embodiments.

[0009] A methyl acrylate slurry is characterized by comprising the following components in parts by weight: 10-30 modified starches, 1-10 urea starches, 1-15 phospholipids, and 10-25 methyl acrylates.

[0010] The weights of the components used in Examples 1-4 are shown in Table 1 (in kg)

[0011] Example Example Example Example modified starch 10.1 20.5 17.6 30.0 Urea starch 1.5 2.3 5.7 10.0 Phospholipids 1.2 10.2 5.3 15.0 Methyl acrylate 10.2 15.3 20.8 25.0

[0012] The slurry prepared in Example 1 is used in T / C and T / R, the sizing rate is 14.82%, the moisture regain rate is 3.5%, the reinforcement rate is 13.68%, the elongation reduction rate is 27.5.0%, and the hairiness is close In good condition and retacked well.

[0013] The above specific embodiments do not limit the technical solutions of the pres...

Abstract

The invention relates to methacrylate slurry which is characterized in that the methacrylate slurry comprises the following components in part by weight: 10-30 parts of modified starch, 1-10 parts of urea starch, 1-15 parts of phospholipid and 10-25 parts of methacrylate. The positive-charge phospholipid contains stearamide (SA), cholesterol derivatives and the like, simultaneously has hydrophilic and hydrophobic groups and can improve the hydrophilcity of surface groups of the methacrylate slurry, effectively improve the moisture absorption and the viscosity of the methacrylate slurry and reduce the use quantity of PVA (Poly Vinyl Alcohol) after being combined with the methacrylate.

Description

technical field [0001] The invention relates to a methyl acrylate size, the viscosity of which does not change much after moisture absorption, and belongs to the field of textile chemistry. Background technique [0002] Methyl acrylate size, polymethyl acrylate and polyacrylamide all have serious re-adhesion phenomenon. One of the reasons is that: the synthetic size contains too many hydrophilic groups, and the strong water absorption makes the dried size The film is easy to absorb moisture and partially dissolve, and has a certain viscosity, so it is easy to have insufficient moisture absorption and re-adhesion on the loom, thereby affecting the weaving effect. Another reason is that the vitrification temperature of the synthetic slurry is too low, and it shows a high elasticity that is easy to deform in the temperature range of use. The property of easy deformation makes the sizing yarns easy to stick to each other, resulting in re-adhesion and affecting the weaving effect...
