How to modify polyester?

Compared with natural fibers, polyester fibers have shortcomings such as low moisture content, poor air permeability, poor dyeing performance, easy pilling and pilling, and easy contamination. In order to improve these shortcomings, chemical modification and physical deformation methods are adopted. Chemical modification methods include:

Main Processes of Spandex Coated Yarn

In the spinning process, the spandex stretch is an important process parameter, which affects the elasticity of the covered Yarn and fabric, as well as the strength, elongation, evenness, and creep properties of the covered yarn. The pre draft ratio of spandex is too small to fully exploit the advantages of good elasticity of elastic fabrics. When the draft is too high, it is difficult to spin, and it is easy to cause yarn breakage, resulting in a decline in product quality; In addition, the percentage content of spandex fiber also affects the elasticity of the covered yarn, with high content and good elasticity. Under certain conditions of spandex fiber specifications, increasing the drafting ratio decreases the percentage content of the spandex fiber, which means that the pre drafting ratio of the spandex fiber is inversely proportional to the percentage content of the spandex fiber in the yarn.

Features of spandex coated products

1、 Air wrapped yarn (ACY) is a yarn that draws wrapped fiber filaments and spandex filaments through a certain type of nozzle at the same time, and forms a rhythmic network of points through regular injection pressure of highly compressed air. The fabric feels soft and smooth;
