Abstract
The invention relates to shape-preserving fibers, textile fabrics, and a method for manufacturing the shape-preserving fibers. The fibers are core-sheath compound fibers which consist of a fiber core layer A and a fiber sheath layer B, wherein the fiber core layer A is formed by polymers with low melting point and high initial modulus, and the fiber sheath layer B is formed by polymers with high melting point and low initial modulus. The core-sheath compound fibers are interlaced with natural fibers to form the textile fabrics. The manufacturing method is to adopt a same-plate bicomponent core-sheath composite spinning component and a spinning machine, to make two compositions with different melting points and with a mass ratio of between 1.5 to 8.5 and 3 to 7 subjected to fusing and spinning through the same-plate bicomponent core-sheath composite spinning component and the spinning machine to form the soft sheath layer B the melting temperature of which is higher than that of the core layer A and the rigid core layer A the melting temperature of which is lower than that of the sheath layer B, and to prepare the core-sheath compound fibers through the sheath layer B and the core layer A. The fabrics or products not only have the presentation qualities of permanent pressing, no corrugation, good elasticity and good shape-preserving property but also have the inherent qualitiesof comfort, sanitation and environmental protection after being subjected to heat-setting, and the shape of the fabrics or the products can not be greatly changed as long as the temperature is lower than the heat-setting temperature.
