In today's textile industry, polyester and spandex, as key materials, directly affect the performance and market competitiveness of fabrics.
Optimal selection of polyester fibers
Polyester fiber is one of the main components of Polyester Spandex Hem Rib, and its performance is directly related to the overall quality of the fabric. Jiangyin Feipeng pays attention to the following key indicators in the selection of polyester fibers:
Fineness optimization: The fineness of polyester fiber has a significant impact on the feel and elasticity of the fabric. Fibers of moderate fineness not only provide a soft touch, but also effectively improve the elasticity of the fabric. Jiangyin Feipeng selects polyester fibers with uniform fineness to ensure that the fabric has excellent elasticity and comfort while maintaining strength.
Improved strength: To enhance the durability of the fabric, Jiangyin Feipeng uses high-strength polyester fibers, which perform well when stretched and torn. The company conducts special treatment on polyester fibers by introducing reinforcing agents or adopting copolymerization technology, which significantly improves its inherent strength and ensures the reliability of the fabric in various usage environments.
Elongation control: Appropriate elongation is an important factor for the fabric to maintain shape stability when subjected to stress. When selecting polyester fibers, Jiangyin Feipeng strictly controls their elongation to ensure that the fabric can quickly recover to its original shape after being stressed, and will not lose shape stability due to excessive elongation.
Spandex Select Strategy
Spandex is popular for its excellent elastic properties and is an important component to enhance the elasticity of Polyester Spandex Hem Rib. Jiangyin Feipeng pays attention to the following aspects in the selection of spandex:
Elastic recovery rate: The elastic recovery rate of spandex is a key indicator to measure its recovery ability. Jiangyin Feipeng chooses spandex with high elastic recovery rate to ensure that the fabric can still maintain good elastic performance after multiple stretching, meeting consumers' high requirements for comfort.
Strength and elongation ratio: The strength and elongation ratio of spandex directly affects its degree of deformation and recovery ability when subjected to force. Jiangyin Feipeng compared various brands and models of spandex and selected spandex with moderate strength and high elongation ratio to achieve a perfect balance between fabric elasticity and strength.
Chemical resistance and stability: Spandex is highly sensitive to chemicals and may lose its elasticity due to the influence of chemicals such as bleach, acid and alkali. To this end, Jiangyin Feipeng gives priority to spandex that has undergone special treatments, such as resistance to chlorine bleaching and anti-aging, which significantly improves its chemical resistance and stability.
