Abstract

In the article, the rheological properties of the adhesive-binding systems used in production enterprises and the newly developed polymer systems are studied. In order to determine the thermal stability of the developed systems, a thermal analysis of thickeners with different compositions was carried out. Mass loss was observed in the heating curve of the thickener based on PAA, PVA and Na-CMS. Endothermic effects observed during heating can be caused by physical phenomena such as liquefaction, evaporation, changes in crystal structure, or chemical reactions such as dehydration. The rheological properties of imported sodium alginate, a thickener based on PAA, PVA and Na-CMS, were compared with the properties of the adhesive-binding polymer system with a new composition. It was found that the rheological properties of the proposed new composition thickener are close to the rheological properties of sodium alginate. It was proved during the experiments that the level of thixotropic recovery is especially high in the polymer system with a new composition. When used as an adhesive-binder for silk fiber fabrics with newly developed thickeners, in addition to improving the physical and mechanical properties of the fabric, the wastewater generated at the stage of washing the fabric after flower pressing does not have a negative impact on the environment and the world of living plants.

基于PAA、PVA和Na-CMS的真丝织物印花组合物的性能

本文研究了生产企业使用的胶粘剂结合体系和新开发的聚合物体系的流变性能。为了确定所研制体系的热稳定性，对不同成分的增稠剂进行了热分析。在PAA、PVA和Na-CMS增稠剂的加热曲线上观察到质量损失。在加热过程中观察到的吸热效应可能是由液化、蒸发、晶体结构变化等物理现象或脱水等化学反应引起的。对进口海藻酸钠(PAA、PVA、Na-CMS)增稠剂的流变性能与新组成的黏着结合聚合物体系的流变性能进行了比较。结果表明，新合成的增稠剂的流变性能接近海藻酸钠的流变性能。实验证明，在新组成的聚合物体系中，触变回收率特别高。将新开发的增稠剂用作真丝纤维织物的粘合剂，除能改善织物的物理机械性能外，织物在花压后洗涤阶段产生的废水不会对环境和植物世界产生负面影响。
