Composite spun fibers have the following performance characteristics:
1. Good mechanical properties
High strength: Composite spun fibers are usually composed of two or more different polymers, which complement and reinforce each other, making them stronger than single fibers. They can be used to manufacture industrial fabrics, tire cords, etc. that require high strength.
High elasticity and elastic recovery: Some composite spun fibers have special molecular or phase structures, which give them good elasticity and elastic recovery ability. For example, parallel composite fibers can produce elasticity and fluffiness similar to wool. Composite elastic fibers have natural spiral curling and good swelling, elasticity, and elastic recovery rate, which can be used to produce elastic fabrics, sportswear, etc
2. Good thermal performance
High temperature resistance: Some composite spun fibers are added with high temperature resistant polymers or inorganic materials, such as high-performance polymers like polyimide, to maintain stable performance in high temperature environments. They can be used as high temperature resistant materials in aerospace, military and other fields.
Low thermal shrinkage: By selecting appropriate polymer combinations and spinning processes, the thermal shrinkage rate of composite spun fibers can be controlled at a low level, ensuring the dimensional stability of fibers and their products when heated. It is suitable for fields that require high dimensional accuracy, such as insulation materials in electronic devices.
3. Improvement of moisture absorption and breathability performance
Moisture absorption enhancement: By combining polymers with good moisture absorption properties with other polymers, the moisture absorption of composite spun fibers can be improved, making the fabric more comfortable to wear. For example, by combining natural fibers with synthetic fibers, the advantages of both can be combined to improve the problem of poor moisture absorption of synthetic fibers
Good breathability: The special structure and composition of composite spun fibers give them good breathability, allowing air and water vapor to freely pass through and improving the comfort of wearing. They are commonly used in sports clothing, outdoor clothing, and other fields.
4. Good chemical stability
Strong corrosion resistance: Some polymers in composite spun fibers have good chemical corrosion resistance, which enables them to resist the erosion of chemical substances such as acid, alkali, salt, etc. They can be used as filter materials, protective clothing, etc. in the fields of chemical engineering, environmental protection, etc
Good anti-aging performance: by adding antioxidants, ultraviolet absorbers and other additives, as well as selecting polymers with high stability, the anti-aging performance of composite fibers has been improved, extending the service life of fibers and their products, which can be used in outdoor building materials, car interiors and other applications exposed to the natural environment for a long time.
5. Outstanding functionality
Antibacterial performance: Adding antibacterial agents or using polymers with antibacterial functions to composite fibers can endow the fibers with antibacterial properties, prevent the growth and reproduction of bacteria and fungi, and are suitable for textiles in medical, health and other fields.
Antistatic performance: By adding anti-static agents or using conductive polymers to composite with other polymers, composite spun fibers can have anti-static properties, reduce the generation and accumulation of static electricity, and avoid the harm caused by static electricity, such as work clothes used in electronic, chemical and other places where static electricity is easily generated.
Shape memory function: Some special composite fibers have shape memory function, which can undergo shape changes under external stimuli (such as temperature, humidity, etc.) and restore their original state after the stimulus disappears. They can be used for research and applications in intelligent textiles, biomedical fields, and other fields
6. Strong processability
Good spinnability: The preparation process of composite spun fibers is relatively mature, and different polymers can be made into composite fibers with various structures and properties through different composite spinning methods, such as parallel type, skin core type, sea island type, etc., to meet different usage needs
Strong compatibility: Composite spun fibers can be blended or interwoven with other fibers to further improve the performance and functionality of the fabric, and expand its application range. For example, blending with natural fibers such as cotton, linen, and silk can improve the comfort and aesthetics of the fabric.
