Problems solved by technology

From the perspective of economy and energy saving, the short process and one-bath method are the development direction of textile finishing. In order to obtain textiles with excellent waterproof performance and good hand feeling, it is necessary to combine waterproofing agent and softener in the same bath, but At present, there is such a problem when compounding that the addition of silicone softener often leads to a decrease in the performance of the waterproofing agent, that is to say, the use of waterproofing agent and silicone softener in the same bath cannot achieve better results

Abstract

The invention discloses a silicone softener used in the same bath with a fluorine-based water repellent and a preparation method thereof. The present invention first prepares unsaturated polyurethane acrylate long carbon chain monomer UPALCM by reacting isocyanate ethyl acrylate with long carbon chain aliphatic alcohol; then adds UPALCM monomer and allyl epoxy polyether into hydrogen-containing silicone oil PHMS according to the proportion , heated up to 60‑90°C, added chloroplatinic acid catalyst to react for 2‑10 hours, and removed low boilers by distillation under reduced pressure to obtain co-modified silicone oil. Then tetramethylhexamethylenediamine acetate and co-modified silicone oil are dissolved in an organic solvent according to the ratio, reacted at a temperature of 70-100°C for 1-20h, and finally the silicone oil is emulsified under the action of a composite emulsifier to obtain A silicone softener used in the same bath with fluorine-based water repellent. The preparation method of the invention is simple, and the prepared softener can not only improve the hand feeling of the fabric, but also not reduce the performance of the waterproof agent, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of silicone softener preparation, in particular to a silicone softener used in the same bath with a fluorine-based waterproofing agent and a preparation method thereof. Background technique [0002] With the progress and development of society, multifunctional textiles have become the mainstream, and people have put forward more and more requirements for textile finishing. Usually, after the textiles are waterproofed, the handle of the fabric tends to harden. To obtain a better handle, the waterproof and soft two-bath method is generally used to achieve it. From the perspective of economy and energy saving, the short process and one-bath method are the development direction of textile finishing. In order to obtain textiles with excellent waterproof performance and good hand feeling, it is necessary to combine waterproofing agent and softener in the same bath, but There is currently such a problem when compo...
