Detailed description of the invention
The present invention is set forth further below in conjunction with detailed description of the invention.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
A kind of Finish of Cotton Fabric with Polycarboxylic Acid anti-crease finishing liquid of the present invention, Finish of Cotton Fabric with Polycarboxylic Acid anti-crease finishing liquid contains polybasic carboxylic acid crease-shedding finishing agent and the 2-6.8g/L catalyst of 30-100g/L, and catalyst is NaOH.
Wherein, polybasic carboxylic acid crease-shedding finishing agent is the saturated polybasic carboxylic acid containing more than three or three carboxyls; Polybasic carboxylic acid crease-shedding finishing agent is one or both the compound in 1,2,3,4-BTCA (BTCA), citric acid (CA); Described COTTON FABRIC is pure cotton fabric or the cotton content blending/MIXED FABRIC at more than 60wt%.
Carry out research to the catalytic mechanism of NaOH to find, thermogravimetric analysis (TG) shows, NaOH can make the one-tenth acid anhydride temperature of BTCA be reduced to about 170 DEG C by about 190 DEG C, improves the one-tenth anhydride reactant activity (as shown in Figure 1) of BTCA molecule.According to the theory becoming ester after XianCheng's acid anhydride, this is conducive to BTCA and effective esterification and crosslinking occurs cellulose, improves wrinkle recovery angle of woven fabrics using viscoelasticity theory.
Infrared test shows, under 160 DEG C of constant temperature, keep 3min, adds the BTCA acid anhydrides absworption peak (1845cm that NaOH makes catalyst
-1near) intensity larger than the acid anhydrides absorption peak strength of pure BTCA (Fig. 2).This also demonstrates the one-tenth acid anhydride that NaOH facilitates BTCA.Possible cause is: adding of NaOH can make BTCA generating portion carboxylic acid sodium salt, and this reduces the intermolecular interaction of hydrogen bond of BTCA, thus improves its one-tenth acid anhydride activity.
For polybasic carboxylic acid finishing of cotton textiles, first polybasic carboxylic acid forms acid anhydrides reactive intermediate, and then acid anhydrides reacts with cellulose generation esterification and crosslinking again, and crosslinking degree is proportional with wrinkle resistance: the degree of cross linking is higher, and the wrinkle resistance of finish fabric is better.Therefore, NaOH improves the one-tenth acid anhydride activity of BTCA molecule, is finally conducive to improving anti-crease finishing effect.
