Preparation and property characterization of chitosan/polyvinyl alcohol filtration film

Cailiao gongcheng, 2020
CS (chitosan)/PVA (polyvinyl alcohol) film was prepared by scraping, and then soaking it in a coagulation bath. The morphology and structure of CS/PVA films at different solidification time were investigated.

Development auxiliaries for dyeing polyester with disperse dyes at low temperatures [PDF]

, 2017
High-molecular weight organic compounds known as carriers are widely used to expedite polyester dyeing at atmospheric pressure at 100 °C. However, carriers are usually poorly biodegradable and can partially plasticize fibres. Also, dyeing at temperatures
