The structural characteristics of the single-layer mesh cloth yarn have a certain relationship with the warmth of the garment, because the structure of the yarn determines whether a static air layer can be formed between the fibers.
The structure of the yarn is fluffy, and there are many voids in the fabric to form an air layer. When there is no wind, there is more static air and better warmth; when there is wind, the air can smoothly pass between the yarns, so the cooling is good.
For a tightly structured yarn, the fabric structure woven therefrom is relatively close, so the air flow is prevented and the warmth is better. When the structure is too tight, the air retained in the fabric is reduced, that is, the static air is reduced. Warmth is poor.
The hygroscopicity of the yarn depends on the fiber properties and the yarn structure. If the filament yarn is smooth, the woven fabric is easy to stick to the body. If the fabric is relatively tight, moisture is difficult to penetrate the fabric. The short fiber yarn has a furry surface that reduces contact with the skin, improves breathability and makes it comfortable to wear.
Second, the impact of single-layer mesh fabric yarn structure on durability
1 The tensile strength, elasticity and wear resistance of the yarn affect the durability of the garment. Affected by the yarn structure.
2 The effect of the yarn structure on the pilling performance: after one fiber breaks in the filament yarn, one end is still attached to the yarn, the broken end is curled by itself, and is pilling by friction; the blended staple fiber yarn has poor cohesion and is easy. Come out.
3 effects on elasticity
Short-staple yarn: a certain external force is applied to the spun yarn. The staple fiber is straightened from the curl, and the external force is canceled, which can restore elasticity. When the staple fiber is straightened and continues to be applied, the staple fiber will slide between the staple fibers. Move or slip, then cancel the external force will produce irreversible deformation.
Filament Yarn: An external force is applied to the filament yarn, and since it does not curl itself, the degree of elongation depends on the properties of the fiber, and therefore its elasticity is small.
The twist has a great influence on the elasticity of the single-layer mesh cloth: the yarn with large twist has a large friction between the fibers, so in the elastic range, it is not easy to be stretched, and the elasticity is relatively poor; and the yarn with small twist, The friction between the fibers is small, relatively easy to be stretched, and the elasticity is good.
