Ordinary filament yarn:
It has a straight and smooth appearance, no hairiness on the surface, generally strong luster, and the fabric has a sense of silk;
Poor fluffy, cool and smooth feel, not easy to pilling, not easy to stain, easy to hook wire, poor coverage;
The fiber strength is fully utilized, with small extensibility and good dimensional stability;
Hygroscopicity depends on the fiber composition. Thermoplastic fiber has poor hygroscopicity, easy to generate static electricity and is airtight.
Untwisted filament yarn:
Each single filament in the untwisted filament yarn is stressed evenly and arranged in parallel and straight, but the transverse structure is extremely unstable, easy to pull out and separate, and the yarn body is relatively soft;
Twisted filament yarn:
Twist filament yarn is stable in both longitudinal and transverse directions, and the uneven fiber orientation can be adjusted in the whole filament yarn by twisting; The yarn is stiff and round.
Textured yarn:
At the same time, it has the characteristics of staple yarn and filament yarn.
The moisture absorption, air permeability, softness, elasticity and warmth retention of the silk are improved;
The yarn surface is dull, fluffy or elastic, and feels soft, so as to improve the covering ability;
The utilization degree of fiber strength is slightly worse than that of filament yarn, and the extensibility is related to the processing method.
The fabric has high dimensional stability and good shape retention;
It maintains the characteristics of easy washing and quick drying of synthetic fiber fabrics;
Processing is more complex than filament.
False twist textured yarn:
The curl state is mainly spiral, with spiral rings in both positive and negative directions; The structure of the yarn is uniform and bulky, with good warmth retention and softness, but the hook wire and fuzzing and pilling; The main features are fluffy and extensibility. Its diameter can be many times higher than that of the precursor. Depending on the twist, the extensibility can also be greatly increased. The elasticity of high elastic wire can reach 2 ~ 4 times or more, and the low elastic wire can be reduced as needed.
