Optimizing the quality of chunky chenille yarn: Precisely controlling the twist to reduce appearance defects

In the textile industry, chunky chenille yarn is deeply loved by consumers for its unique texture and appearance. However, in the production process, appearance defects such as exposed core yarn, uneven feather yarn or poor joints often occur, which not only affects the beauty of the product, but also reduces its market competitiveness. In order to improve the quality of chunky chenille yarn and reduce these appearance defects, it is particularly important to accurately control the key technical parameters in the production process, among which the twist of the core yarn and the feather yarn is a key control point.

Exposed core yarn and uneven feather yarn are common appearance problems in chunky chenille yarn. Exposed core yarn refers to the core yarn exposed on the surface of the yarn, which destroys the uniformity and beauty of the yarn. And uneven feather yarn refers to the uneven distribution of fibers (feather yarn) wrapped around the core yarn, resulting in uneven yarn appearance. These problems often stem from insufficient twist between the core yarn and the feather yarn, which makes it impossible for the core yarn to tightly bind the feathers, resulting in hair loss and exposed core yarn during subsequent processing or use.

In order to solve these problems, increasing the twist of the core and feather yarn is an effective means. Twist refers to the number of twists per unit length of yarn, which determines the tightness and strength of the yarn. By appropriately increasing the twist, the bonding force between the core and the feather yarn can be enhanced, so that the core can bind the feathers more tightly, thereby reducing the phenomenon of hair loss and core exposure. At the same time, increasing the twist can also help improve the uniformity and stability of the yarn and improve the overall quality of the product.

However, the increase in twist is not the more the better. Too high twist will cause the yarn to become too tight and hard, lose its original softness and fluffiness, and may even cause problems such as weaving bias. Weaving bias refers to the skew phenomenon of yarn due to excessive twist during the weaving process, which seriously affects the appearance and performance of the fabric. Therefore, when determining the twist parameters, it is necessary to fully consider the product's use needs and market needs to find the best balance point.

In order to determine the best twist parameters, companies need to conduct a lot of experiments and research. During the test, yarns with different twists can be selected for weaving to observe the changes in performance indicators such as appearance quality, feel, and strength. Through comparative analysis, we can find out the twist range that can effectively reduce appearance defects and maintain good yarn performance.

In addition to testing to determine the optimal twist, enterprises also need to make timely adjustments based on actual production conditions. Because in the actual production process, factors such as the batch of raw materials, the state of equipment, and the skill level of operators may affect the quality of yarn. Therefore, enterprises need to establish a complete quality management system to strictly monitor and manage each link in the production process to ensure stable and reliable yarn quality.
