台州How does the composition of the core yarn affect its quality?

Core yarn is a type of yarn made up of two or more different fibers, usually consisting of one coarse fiber wrapped around a fine fiber. This structure gives core yarn a range of advantages and characteristics in terms of quality. The composition of the core yarn has a significant impact on its quality. The effect of core yarn composition on quality is discussed in detail below.

First of all, the outer fiber of the core yarn plays a key role in its quality. The choice of cover fiber determines the look and feel of the yarn. For example, if a smooth, soft cotton fiber is used as the cover fiber, the yarn will have a smooth, soft handfeel and is suitable for making high-grade garments. If rough hemp fiber is chosen as the cover fiber, the yarn will show rough and textured characteristics, suitable for making outdoor equipment. In addition, the strength and abrasion resistance of the outer fiber will also affect the quality of the yarn. If the strength of the overcoat fiber is low, the yarn will be easy to break and not durable; while if the abrasion resistance of the overcoat fiber is poor, the yarn will be easy to pilling or hairiness, which will affect the quality.

Secondly, the core fiber of core yarn also has an important impact on its quality. The choice of core fiber determines the tensile strength and elasticity of the yarn. For example, if the choice of high strength polyester fiber as the core fiber, the tensile strength of the yarn will increase, suitable for the production of products requiring tensile properties, such as swimwear and sportswear. If an elastic fiber such as spandex is used as the core fiber, the elasticity of the yarn will be increased, which is suitable for products that require resilience properties, such as socks and tights.

In addition, the interaction of the fibers in the core yarn has an impact on the quality. The interaction between the fibers determines the stability and abrasion resistance of the yarn. If the fiber interactions are strong, the yarn is more stable and less prone to deformation, whereas if the fiber interactions are weak, the yarn tends to be loose and prone to deformation and pilling. In addition, the interaction between fibers also affects the abrasion resistance of the yarn. If the interaction between the fibers is strong, the yarn is less prone to pilling or feathering; while if the interaction between the fibers is weak, the yarn is prone to pilling or feathering.

The composition of the core yarn also has an effect on its quality stability. Different fibers have different chemical properties and thermal stability. If the core yarn consists of two fibers with similar chemical properties, the yarn is more stable and less prone to discoloration or fading. If the core yarn consists of two fibers with large differences in chemical properties, the yarn is prone to discoloration or fading. In addition, different fibers have different thermal stability. If the spinning temperature used in spinning exceeds the melting point of the fibers, the fibers will melt or burn, affecting the quality.

In summary, the composition of the core yarn has an important influence on its quality. The selection of outer fibers determines the appearance, feel and abrasion resistance of the yarn; the selection of inner core fibers determines the tensile strength and elasticity of the yarn; the interactions between the fibers determines the stability and abrasion resistance of the yarn; and the chemical properties and thermal stability affects the discoloration and fading of the yarn. Therefore, when manufacturing core yarns, it is necessary to carefully select and match various fibers to ensure that the output yarn has excellent quality.
