Spinning chenille yarn differs from spinning other cotton yarns, therefore, the operational control rules also differ. The rules and common problems are as follows:
a) During the operation, operators should frequently check if the cutting blade is dull and replace it if necessary, otherwise it may affect the cutting quality.
b) The use of spacers and rollers has a significant impact on the yarn count. Operators should continuously improve their estimation and feel capabilities to ensure the spun yarn is uniform and consistent.
c) Before using a new spacer, each side and corner should be sanded smooth and polished to a gloss level of V11 or higher using sandpaper to ensure the smooth wrapping and draping of the chenille veil.
d) Yarn defects caused by breakage or stopping should be marked with knots to facilitate inspection and repair by winding operators. If defective yarns such as loose yarn or exposed core are found, the processing technology should be adjusted scientifically, the machinery repaired, and the damaged yarn bobbins handed over to specialized staff for handling.
e) Regularly maintain the machinery to ensure it is clean and tidy, and that the connecting textile channels are unobstructed to prevent defects caused by fly waste.
Chenille yarn, also known as spiral long-pile yarn, is a new type of yarn. It is spun using two strands as copper core cables, with the loose yarn sandwiched in the center by twisting. Therefore, it is also figuratively called corded cotton yarn.
Chenille yarn, with its characteristics of being thick, soft to the touch, and lightweight yet durable, is widely used in the home textile and knitwear industries, creating a new trend in product development; it also brings good economic benefits to manufacturers.
Chenille Machine Working Principle and Operation Techniques
The chenille spinning machine, also known as a corded spinning machine, is a new type of spinning equipment used to produce chenille yarn. The domestically produced model of this machine was developed by adapting and redesigning the production plan based on the absorption and assimilation of internationally exhibited prototypes. The product it produces is called chenille yarn, also known as spiral yarn or broken yarn, a new type of fancy yarn. Because of its rope-like appearance, it is also called rope yarn. It is spun using two strands as the core yarn, with short, blade-cut pile yarn sandwiched between them through twisting. Chenille yarn, with its caterpillar-like appearance, full, loose pile, soft hand feel, and vibrant colors, produces fabrics that are rich and lightweight, and is widely used in home textiles, knitted apparel, automotive accessories, and antique-style fabrics, among many other fields. In recent years, it has become a new highlight in the development of new textile products and a new growth point for enterprise economic benefits.
Operating Techniques and Precautions
Spinning chenille yarn differs from spinning other yarns, therefore, the operating requirements also differ. The requirements and precautions are as follows:
a) During the operating process, operators should frequently patrol and check if the cutting blades are dull. Replace them promptly, otherwise, the cutting quality will be affected.
b) The condition of the spacer plates and rollers directly affects the yarn count. Operators must continuously improve their visual inspection and feel skills to ensure uniform and consistent yarn quality.
c) Before using a new spacer plate, all sides and edges should be sanded smooth and polished with wet sandpaper to a smoothness level of V11 or higher to ensure smooth yarn wrapping and sliding.
d) Yarn defects caused by breakage or shutdown should be knotted for inspection and repair by winding workers. If defective yarns such as fuzzy yarn or exposed core are found, the process should be adjusted promptly, equipment inspected, and the damaged yarn bobbins handed over to designated personnel for handling.
e) Regularly maintain the machine cleanliness and tidiness, and unblock the spinning channel to avoid fly waste defects.
