Based on this, in order to improve the production technology of super-flexible spandex, this paper summarizes the optimization points of three production technology factors from three aspects: operation, facilities and formula, and puts forward corresponding technology upgrading methods around these optimization points, and constructs a set of super-flexible spandex production technology upgrading scheme. After a period of use, it is found that this scheme can effectively improve the production technology of super-flexible spandex and enhance the production level of super-flexible spandex. In this paper, three technical upgrading methods of super-flexible spandex are elaborated in detail, including optimizing spinning process operation, improving spinning process facilities and adjusting spinning process formula, as well as improving PTG molecular weight, changing PTG/MDI molar ratio, reducing additive dosage, adjusting spinneret capillary hole size, appropriately reducing spinning tension and improving spinning process, hoping to help the development of polyester fiber material manufacturing industry. It realized the in-depth analysis of the process system construction of super-flexible spandex, hoping to provide assistance for the development of polyester fiber material manufacturing industry.展开更多

The fabric structure, weight, types of fibers, and fiber blend proportion influence the bursting strength parameter. The tenacity of polyester fiber is better than cotton and spandex. The study focused on predicting knit fabric bursting strength test value using different fibers (cotton, polyester, and spandex) with varying percentages of the blend ratio. This study used fifteen categories of blended fabrics. The Pearson Correlation and the hypothetical ANOVA regression analysis were conducted to do the statistical significance test. The experimental result reveals that the bursting strength test result increased with the increased percentage of polyester and suggested a suitable regression equation. The dominance of the polyester fiber was observed throughout the experiment, i.e., the higher the polyester blend proportion, the higher the bursting strength value. The inclusion of polyester in blends can reduce the cost of fabric. The developed prediction model or equation can help the fabric manufacturer make appropriate decisions regarding getting the expected bursting strength. The researcher hopes that the findings from this study will motivate new researchers, advanced researchers, and the textile manufacturing industry.展开更多

By using high particle size pigment carbon black and hyperdispersant, selecting scientific control conditions and appropriate amount of carbon black, the black stock solution meeting the requirements of dry spandex spinning can be produced by using stock solution coloring method. Effectively promote the industrial production of black spandex on the existing production line. Based on this, this paper explores the research process, production process and key technical points of dry spinning black spandex production technology.展开更多
