New criteria for the qualitative assessment of the relaxation-recovery properties of polymer textile materials for technical purposes, obtained on the basis of the study of parameters-characteristics of mathematical models of the relaxation and recovery processes of these materials, are proposed. The developed criteria allow carrying out a qualitative assessment of the relaxation-recovery properties of polymer textile materials for technical purposes, which significantly reduces the technical and economic costs of designing these materials with specified relaxation and recovery properties, since there is no need to manufacture pilot batches of these materials.

用于技术目的的聚合物纺织材料的松弛恢复特性的定性评估标准

提出了基于技术目的对聚合物纺织材料的松弛-恢复特性进行定性评估的新标准，该标准是基于对这些材料的松弛和恢复过程的数学模型的参数-特征研究而获得的。制定的标准允许对出于技术目的的聚合物纺织材料的松弛-恢复特性进行定性评估，因为无需制造试点，从而大大降低了设计具有特定松弛和恢复特性的材料的技术和经济成本。这些材料的批次。
