Modification of Fiber Engineering
Fiber engineering can be based on the chemical modification of spinning materials or the modification of spinning and fiber post-processing technology; Or both chemical modification and physical modification. The obvious examples of chemical modification are the improvement of the stability of polyp...

People transform synthetic fibers
Synthetic fiber nylon ties lack hydrophilic groups. The hygroscopicity of polyethylene and polypropylene is almost zero, and that of polyester is only 0.4%, which is far from meeting people's wearing requirements. Therefore, people began to study the improvement of hygroscopicity of synthetic fibers...

Connection between crystalline polymers
From a thermodynamic point of view, the strain applied to the polymer reduces the amorphous state, resulting in the decrease of melting point, the increase of melting point and the increase of undercooling at a given temperature. However, in the spinning process, the temperature of the polymer gener...
