Factors affecting pilling
Effect of the yarn: The more the crimping waveform of the fiber, the less the fiber is easy to stretch when twisted, and the fiber tends to loosen and slip during the rubbing process to form a furry on the surface of the yarn. For this reason, the better the crimping property of the fiber, the easier it is to pilling. The finer the fiber, the more the fiber ends are exposed on the surface of the yarn, and the better the fiber flexibility, so the fine fibers are easier to entangle the pilling than the coarse fibers. And for fiber length
Generally speaking, shorter fibers are easier to pilling than long fibers. In addition to the influence of the number of ends of the fibers, the friction and cohesion between the long fibers are large, and it is difficult for the fibers to slide to the surface of the fabric, and it is difficult to entangle the balls. The twist of the yarn and the smoothness of the surface have a great influence on the pilling. The yarn with high twist has tight cohesion between the fibers. When the yarn is subjected to friction, the fiber slips less from the yarn and the pilling phenomenon decreases. However, the sweater is a soft fabric, and the excessively high twist makes the fabric hard, so it is not possible to prevent the pilling by increasing the twist. The effect of the yarn finish, the smoother the yarn, the shorter and less the surface hair, so the smooth yarn is not easy to pilling.
The influence of the fabric structure: the fabric with loose texture of the fabric is easier to pilling than the fabric with tight structure. High-grade fabrics are generally tighter, so low-grade fabrics are easier to pilling than high-grade fabrics. The flat surface of the fabric is not easy to pilling, and the uneven surface of the fabric is easy to pilling. Therefore, the anti-pilling property of the fat flower fabric, the ordinary flower fabric, the rib fabric, and the jersey fabric is gradually increased.
The influence of dyeing and finishing process: After dyeing and finishing the yarn or fabric, it will have a greater impact on the pilling resistance, which is related to the dye, auxiliary, dyeing and finishing process conditions, and the yarn dyed by the hank yarn is more than the scattered yarn. The dyed or top-dyed yarn is easy to pilling; the fabric dyed with the jersey is easier to pilling than the woven fabric; the fabric is shaped, especially after finishing with the resin, its pilling resistance is greatly enhanced.
Effects of wearing conditions: The greater the friction experienced by sweaters fabric when worn, the more the number of frictions it receives, the more severe its pilling phenomenon.
Anti-pilling finishing method and process
Cardigan is a molded product. It has certain difficulties in using singeing or shearing to prevent pilling. The anti-pilling finishing methods commonly used today mainly include mild fluffing and resin finishing. The resin finishing method works better.
