1. Warmth retention
The structural characteristics of yarn have a certain relationship with the warmth retention of clothing, because the structure of yarn determines whether a static air layer can be formed between fibers.
The yarn structure is fluffy and there are many gaps in the fabric, forming an air layer. When there is no wind, there is more still air and better warmth retention; when there is wind, the air can pass smoothly between the yarns, so it is cool Sex is better.
For yarns with a tight structure, the structure of the fabric woven from it is also relatively tight, so the air flow is blocked and the warmth retention is better; when the structure is too tight, the air trapped in the fabric is reduced, that is, it is still. If the air is reduced, the warmth retention will be poor.
2. Hygroscopicity
The hygroscopicity of yarn depends on fiber characteristics and yarn structure. If the filament yarn is smooth, the woven fabric will stick to the body easily. If the fabric is tight, it will be difficult for moisture to penetrate the fabric. The short fiber yarn has a furry surface, which reduces contact with the skin, improves breathability and makes wearing comfortable.
2. The influence of yarn structure on durability
① The tensile strength, elasticity and wear resistance of yarn affect the durability of clothing. Affected by yarn structure.
②The influence of yarn structure on the pilling performance: after one fiber in the filament yarn is broken, one end is still attached to the yarn, and the broken end curls itself, causing friction and pilling; blended short fiber yarn, hugging The resultant force is poor and easy to come out.
③ Effect on elasticity
Staple fiber yarn: Apply a certain external force to the staple fiber yarn, and the staple fiber will be straightened from the crimp. When the external force is removed, the elasticity can be restored; and after the staple fiber is straightened If you continue to apply force to it, the short fibers will slip or slip. At this time, if the external force is removed, irreversible deformation will occur.
Filament yarn: When external force is applied to filament yarn, since it does not curl, the degree of elongation depends on the performance of the fiber, so its elasticity is small.
Twist also has a great impact on elasticity: yarns with large twists have greater friction between fibers, so within the elastic range, they are not easily stretched and have relatively poor elasticity; while yarns with small twists, fibers The friction force between them is small, it is relatively easy to be stretched and has good elasticity.
