Embodiment 1

[0027] Add 1.27Kg of octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.78Kg of secondary alcohol polyoxyethylene ether (8), 0.26 Kg of paraffin emulsifier and 90Kg of water into a 500Kg reaction kettle, and heat up while stirring to 60~65℃, then slowly add 7.69KgC which has been preheated at 60~65℃ 16-18 Advanced alkyl ketene dimer, fully stirred to get 10% concentration of waterproof synergist.

[0028] Take 0.5Kg of the above-mentioned waterproof synergist, and 2.0 Kg of commercially available TG5601 (C 6 Perfluoroacrylic acid waterproofing agent) mixed, added to 97.5Kg of water, prepared waterproofing agent solution. Then, pad the polyester fabric with the above water-repellent agent solution, and the excess rate is 55-60%, and then dry and treat it at high temperature (170°C) for 3 minutes on a hot-air stenter setting machine to obtain a polyester fabric with waterproof function.

Embodiment 2

[0030] Add 0.67Kg octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.50Kg secondary alcohol polyoxyethylene ether (8), 0.16 Kg paraffin emulsifier and 92Kg water into a 500Kg reaction kettle, and heat up while stirring to 60-65°C, then slowly add 6.67KgC preheated at 60-65°C 16-18 Advanced alkyl ketene dimer, fully stirred to get 8% concentration of waterproof synergist.

[0031] According to the method of embodiment one, handle polyamide fiber, obtain the nylon fabric with waterproof function.

Embodiment 3

[0033]Add 1.48Kg of octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.99Kg of secondary alcohol polyoxyethylene ether (8), 0.33 Kg of paraffin emulsifier and 85Kg of water into a 500Kg reaction kettle, and heat up while stirring to 60~65℃, then slowly add 11.20KgC which has been preheated at 60~65℃ 16-18 Advanced alkyl ketene dimer, fully stirred to get 14% concentration of waterproof synergist.

[0034] According to the method of Example 1, the polyester / polyamide ultrafine composite fiber is processed to obtain a polyester / brocade fabric with waterproof function.

Abstract

The invention belongs to the technical field of fine chemical engineering and relates to a waterproof synergistic agent for improving the textile water-proof finish. The waterproof synergistic agent consists of a synergistic agent, an emulsifying agent and water, and is characterized in that the mass sum of the synergistic agent and the emulsifying agent accounts for 8 to 15 percent of the mass of the waterproof synergistic agent, the mass ratio of the synergistic agent to the emulsifying agent is 10:(2-3), the synergistic agent is selected from C16-C18 high-grade alkyl ketene dimmer, the emulsifying agent is a mixture formed by octadecyl dimethyl ethoxy hyamine, secondary alcohol ether (8) and a paraffin emulsifier, and in addition, the mass ratio of the octadecyl dimethyl ethoxy hyamine to the secondary alcohol ether (8) to the paraffin emulsifier is (4-5):3:1. After the waterproof synergistic agent is added to C4 or C6 short-chain perfluor crylic acid waterproof emulsion, the waterproof effect and the durability of a perfluor crylic acid waterproof agent can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals and relates to a waterproof synergist for improving the waterproof finishing of textiles. Background technique [0002] In the textile printing and dyeing process, the waterproof finishing of textile materials is a commonly used finishing process. The waterproofing agent mostly uses organic fluoropolymers with low surface tension. For example, the most widely used textile waterproofing on polyester fibers and polyamide fibers perfluorooctane acrylic emulsion, but perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS) and their salts accumulate in the environment and in human and animal tissues. They are organic polymers that are difficult to degrade. Potential hazard to human health and the environment. Therefore, there are strict restrictions on the use of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) at home and abroad. [0003] With the strict restrict...
