What are the preparation methods of composite spun fibers
2025-05-06The preparation methods of composite spun fibers mainly include the following: 1. Two component composite spinning: Two different polymer melts or solutions are separately input into the same spinning component, and after merging at the nozzle, they are extruded to form composite fibers. According to the distribution patterns of the two components in the fiber, it can be divided into various type

Why is polyester fiber used on shirts
2025-04-29The use of polyester fiber on shirts is mainly based on its advantages of being firm, wrinkle resistant, easy to wash and dry, durable and economical. The following is a specific introduction: 1. Wrinkle resistant: Polyester fibers have high strength and elastic modulus, are not easily deformed, and can maintain a good fit of the shirt, making it more crisp to wear. Even after multiple wearing an

Why is the light resistance of polyester fiber good
2025-04-15Polyester fiber has good light resistance for the following reasons: 1. stability of molecular structure: the molecular chain of polyester fiber contains benzene ring structure, which has high conjugation stability, can absorb and scatter ultraviolet rays, and reduce the damage of ultraviolet rays to the molecular chain. At the same time, the ester group (-coo-) in the polyester molecular chain f

How to change the fiber properties of composite spun fibers
2025-04-08Composite spun fibers change their properties in various ways, mainly including the following aspects: 1. Combining the characteristics of different polymers: Composite spun fibers are composed of two or more polymers with different properties. For example, by combining high-strength polyester with soft polyamide, the fibers can have both the high strength of polyester and the soft feel of polyam

What are the specific effects of the water absorption of polyester fibers on the comfort of clothing
2025-03-18The poor water absorption of polyester fibers has both negative and positive effects on clothing comfort, as follows: 1. Negative impact Heat sensation: Due to the low water absorption of polyester fibers, sweat discharged from the skin surface cannot be absorbed in a timely manner. Sweat will accumulate between the skin and clothing, causing the skin to feel damp and stuffy, especially i
