Embodiment 1

[0025] An agent for improving wet rubbing fastness against hard water comprises the following components by weight: 88% of weak cationic water-based polyurethane, 10% of hydroxyethylene diphosphonic acid, and 2% of defoaming agent. Accurately weigh the above-mentioned components, add hydroxyethylidene diphosphonic acid and defoamer to the weak cationic water-based polyurethane while stirring, mix evenly, filter and discharge the material, and obtain the hard water wet rubbing fastness improving agent.

[0026] Preparation of stenter working solution: sequentially add softener 30g / L, crosslinking agent 20g / L, color fixing agent 30g / L, hard water wet rubbing fastness enhancer 30g / L, pH regulator 1 g / L; , the temperature is 31°C, and the pH value is 4.98.

[0027] Finish the prepared stenter working liquid on the C32*21 133*60 brushed printed fabric by dipping and rolling, the amount of liquid is 65~68%, and then pre-dry with hot air at 105 ℃, and then 160 on the stenter Bake at...

Embodiment 2

[0030] A hard water-resistant wet friction enhancer comprises the following components by weight: 85% of weak cationic water-based polyurethane, 12% of cetyltrimethylammonium chloride, and 3% of defoamer. Accurately weigh the above-mentioned components, add the cosolvent and defoamer into the weak cationic water-based polyurethane while stirring, mix evenly, filter and discharge the material, and obtain the hard water wet rubbing fastness improving agent.

[0031] Preparation of stenter working solution: sequentially add softener 40g / L, crosslinking agent 30g / L, color fixing agent 30g / L, hard water wet rubbing fastness enhancer 40g / L, pH regulator 1.5 g / L; , the temperature is 35°C, and the pH value is 4.53.

[0032] Finish the prepared stenter working liquid on the C32*21 133*60 brushed printed fabric by dipping and rolling, the amount of liquid is 65~68%, and then pre-dry with hot air at 105 ℃, and then 160 on the stenter Bake at ~170°C for 30 s. Test the dry and wet rubbi...

Embodiment 3

[0035] A hard water-resistant wet friction enhancer comprises the following components by weight: 85% of weak cationic water-based polyurethane, 10% of propylene bis(dodecyl dimethyl ammonium bromide), and 5% of defoamer. Accurately weigh the above-mentioned components, add the cosolvent and defoamer into the weak cationic water-based polyurethane while stirring, mix evenly, filter and discharge the material, and obtain the hard water wet rubbing fastness improving agent.

[0036] Preparation of stenter working solution: sequentially add softener 40g / L, crosslinking agent 30g / L, color fixing agent 20g / L, hard water wet rubbing fastness enhancer 40g / L, pH regulator 0.5 g / L; , the temperature is 36°C, and the pH value is 5.67.

[0037] Finish the prepared stenter working liquid on the C32*21 133*60 brushed printed fabric by dipping and rolling, the amount of liquid is 65~68%, then pre-dry with hot air at 105 ℃, and then put it on the stenter at 160 Bake at ~170°C for 30 s. Tes...

Abstract

The invention discloses a hard-water-resistant wet rubbing fastness improver and preparation and application methods thereof. The hard-water-resistant wet rubbing fastness improver comprises, by weight percentage, 80-94% of weak cation type waterborne polyurethane, 5-15% of cosolvent and 1-5% of defoaming agent. The preparation method includes: accurately weighing the components above, adding the cosolvent and the defoaming agent into the weak cation type waterborne polyurethane while stirring, evenly mixing, and filtering and discharging to obtain the hard-water-resistant wet rubbing fastness improver. The hard-water-resistant wet rubbing fastness improver has the advantages that the hard-water-resistant wet rubbing fastness improver is insensitive to water hardness and salt content, adaptive to production water quality, capable of being used along with post-finishing auxiliaries such as commonly used softening agents, color fixing agents and crosslinking agents, capable of improving the wet rubbing fastness of sueded extra-dark-color active printed or dyed products from 1-2 level to 2-3 level, capable of avoiding energy waste and production efficiency lowering caused by two stentering and capable of solving the problem of oil spot sticky dirt on the surface of cloth at the same time.

Description

technical field [0001] The invention relates to a hard water-resistant wet rubbing fastness improving agent and a preparation and use method thereof, which belong to the technical field of textile printing and dyeing post-finishing. Background technique [0002] After my country's accession to the WTO, the quality requirements of textiles are in line with international standards, and the requirements for the color fastness of dyed fabrics are getting higher and higher. AATCC, ISO and GB stipulate that the wet rubbing fastness of dyed fabrics is qualified at grade 2~3, and foreign customers often require it to reach grade 3 or even grade 3~4. At present, the wet rubbing fastness of some dark red and black series pure cotton brushed fabrics The fastness can only reach level 1~2. One of the main reasons for the poor wet rubbing fastness of fabrics is the floating color transfer of water-soluble dyes and the mechanical friction transfer of colored fiber particles, that is, the ...
