Problems solved by technology

Among polycarboxylic acids, butane tetracarboxylic acid (BTCA) has the best finishing effect, but its application is limited due to its high price, high baking temperature, easy to cause yellowing of fabrics, and poor solubility in water.

Embodiment 1

[0023] Compound emulsifiers were prepared with different ratios of SPAN80: Tween80: OP-15, and emulsions with different concentrations of CSA-1 were prepared. The results are shown in Table 1;

[0024] Table 1

[0025]

[0026] As can be seen from Table 1, the CSA-1 emulsions prepared by the 6 formulations in Table 1 can meet the requirements of ready-to-use, and the emulsions prepared by (5), (3), and (4) have a relatively long stable time.

Embodiment 2

[0028] Prepare CSA-1 emulsion earlier by formula (1) among the embodiment 1; Prepare finishing solution again: CSA-1 emulsion 120g / L (the quality of CSA-1 emulsion is to the volume of finishing solution), ammonium sulfate 10g / L (sulfuric acid The quality of the amine to the volume of the finishing solution), and the remaining amount of water. For padding fine plain cloth fabric, the liquid retention rate is 70% → pre-baking at 90°C for 2min → baking at 150°C for 1.5min. Determination of wrinkle recovery angle is shown in Table 2.

Embodiment 3

[0032] Prepare CSA-1 emulsion earlier by formula (2) among the embodiment 1; Prepare finishing solution again: CSA-1 emulsion 130g / L (the quality of CSA-1 emulsion is to the volume of finishing solution), ammonium sulfate 10g / L (sulfuric acid The quality of the amine to the volume of the finishing solution), and the remaining amount of water. Padding cotton poplin fabric, liquid retention rate 70% → pre-baking at 90°C, 2min → baking at 150°C, 1.5min. Determination of wrinkle recovery angle is shown in Table 3.

Abstract

The invention relates to a finishing method using a cotton and cotton-containing fabric non-ironing finishing agent. The method comprises the following steps of: (1) mixing SPAN80, Tween 80 and OP-15 in a mass ratio of 2-5:2-5:1 to prepare a compound emulsifying agent and mixing the compound emulsifying agent and CSA-1 in a mass ratio of 5-10:90-95 to prepare CSA-1 emulsion; (2) mixing the CSA-1 emulsion and ammonium sulfate to prepare finishing liquid; and (3) padding a textile fabric, and pre-baking and baking the textile fabric to obtain a needed textile fabric. The finishing agent has theadvantages of low price, low needed baking temperature, good finishing effect, little environment pollution and good application prospect.

Description

technical field [0001] The invention belongs to the field of anti-wrinkle and non-ironing finishing of textile fabrics and garments, in particular to a finishing method using a non-ironing finishing agent for cotton and cotton-containing fabrics Background technique [0002] Although cotton fabric is soft and comfortable to wear, it is easy to wrinkle and shrink, making it difficult to handle. Anti-wrinkle finishing can improve the elasticity, wrinkle recovery and dimensional stability of cotton fabric. Cotton fibers have crystalline and amorphous regions, and the amorphous part determines the flexibility of the fiber. When the fabric is wrinkled, the fibers are bent and deformed by the external force, and cannot be completely restored to their original shape after the external force is removed. In places with low side order, the macromolecules are not arranged neatly, and the hydrogen bonds in the region are deformed when subjected to external forces, and the strength of th...
