在紡製高支紗時，長絨棉的物理性能決(jue) 定著成紗質量，在一定比例範圍內(nei) ，長絨棉含量不同，成紗質量也會(hui) 有顯著差異。尤其是對成紗條幹CV、單紗斷裂強度、毛羽、成紗紗疵（細節、粗節、棉結）影響較明顯。

When spinning high count yarn, the physical properties of long staple cotton determine the quality of the yarn. Within a certain proportion range, the quality of the yarn will also vary significantly depending on the content of long staple cotton. Especially, it has a significant impact on the yarn evenness CV, single yarn breaking strength, hairiness, and yarn defects (details, coarse knots, and neps).

在紡紗過程中，隨著長絨棉含量的增加而逐漸降低。這是因為(wei) 隨著長絨棉含量的增加，纖維平均號數降低，紗條截麵中纖維根數較多，對改善條幹具有一定的作用。在細絨棉中摻入一定數量的長絨棉，可以有效的提高成紗條幹均勻性，以更好的滿足用戶的要求。

During the spinning process, it gradually decreases with the increase of long staple cotton content. This is because as the content of long staple cotton increases, the average number of fibers decreases, and there are more fibers in the cross-section of the yarn, which has a certain effect on improving the evenness. Adding a certain amount of long staple cotton to fine velvet cotton can effectively improve the evenness of the yarn and better meet the requirements of users.

斷裂強度：由於(yu) 成紗能力與(yu) 纖維細度和長度均有一定的關(guan) 係，纖維長度長、纖維利用率高，紗條中散亂(luan) 纖維和短纖維較少，纖維細度細，紗條斷麵內(nei) 的纖維根數多，抱合力增加，因而當在細絨棉配棉中混入長度較長、細度較細的長絨棉後，成紗斷裂強度顯著增加。長絨棉含量單加到25%、由75%增加到85%時，斷裂強度增加的幅度較大，長絨棉含量每增加10個(ge) 百分點，斷裂強度增幅在12%以上；在其他比例段，長絨棉含量每增加10個(ge) 百分點，斷裂強度增加幅度在3%-6%左右。

Breaking strength: Due to the relationship between yarn forming ability and fiber fineness and length, the fiber length is long and the fiber utilization rate is high. There are fewer scattered fibers and short fibers in the yarn, and the fiber fineness is fine. There are more fibers in the cross-section of the yarn, and the cohesion is increased. Therefore, when long and fine staple cotton is mixed with fine cotton, the breaking strength of the yarn significantly increases. When the content of long staple cotton is increased to 25% or from 75% to 85%, the increase in breaking strength is significant. For every 10 percentage points increase in long staple cotton content, the increase in breaking strength is over 12%; In other proportion ranges, for every 10 percentage points increase in the content of long staple cotton, the increase in breaking strength is around 3% -6%.

毛羽：是指伸出紗線體(ti) 表麵的纖維。毛羽性狀是紗線的基本結構特征之一。在多數情況下，紗線毛羽不僅(jin) 影響織物的透氣、抗起毛起球、外觀、織紋清晰和表麵光滑等。一般纖維愈整齊，短纖維含量愈低，成紗表麵越光潔，毛羽也會(hui) 相應減少。這就類似於(yu) 在女生在編辮子的時候，長發辮子總是比短發辮子更為(wei) 整齊、不毛躁。

Hairiness: refers to the fibers that protrude from the surface of the yarn body. Hairiness is one of the basic structural characteristics of yarn. In most cases, yarn fuzziness not only affects the breathability, anti pilling, appearance, clear texture, and smooth surface of the fabric. The more regular the fibers are, the lower the content of short fibers, the smoother the surface of the yarn, and the corresponding reduction in hairiness. This is similar to when girls braid their hair, long hair braids are always more neat and less frizzy than short hair braids.

成紗紗疵：排除紡紗過程中機械、環境、操作、工藝等因素對紗疵的影響。一般來看，隨著長絨棉含絨量的增加，紗疵是逐漸減少的，這是由於(yu) 隨著長絨棉含量的增加，纖維平均長度變長、平均細度變細，紗線中纖維利用率高，抱合力增加，紡紗過程中浮遊纖維較少，產(chan) 生紗疵的機會(hui) 就減少。

Finished yarn defects: eliminate the influence of mechanical, environmental, operational, and technological factors on yarn defects during the spinning process. Generally speaking, as the fiber content of long staple cotton increases, yarn defects gradually decrease. This is because with the increase of long staple cotton content, the average fiber length becomes longer, the average fineness becomes finer, the fiber utilization rate in the yarn is higher, the cohesion increases, and there are fewer floating fibers during the spinning process, reducing the chance of yarn defects.
