What Is The General Control Of The Yarn Return Rate?

Under the premise of the design of the suction yarn when the self-linking joint is completed, it is directly linked to the number of knots. Therefore, the so-called yarn return rate should be the combined result of the quality of the yarn under the previous spinning process, the cutting amount of the electronic yarn clearer and the primary winding rate of the automatic winder. It is not independently controlled on the automatic winder. index of.

Self-winding yarns often have the phenomenon of chaotic yarns and mesh yarns (spider webs), generally starting from the following aspects:

(1) Check if the tension disc is caught with debris, chaotic yarn and return wire and clean it;

(2) Check if the suction negative pressure is between 38-42 and adjust;

(3) Check the big and small nozzles and mouth for burrs and clean;

(4) Check if the presser bar is deformed and adjusted;

(5) Check whether the process tension design is reasonable and optimized;

(6) Check whether the distance between the surface of the package and the large nozzle is reasonable and optimized;

(7) Slowly slow down the drum speed;

(8) Set the suction function of the large nozzle to 3 times (the nozzle stops rotating after 3 times of suction, avoiding repeated invalid actions). If the yarn is not sucked, the driver will handle it and look at the yarn first. Whether there is a mess on the surface, and then peel off, and then drive.

Shang Shande produces all kinds of hemp yarn, pure cotton yarn, polyester viscose yarn, polyester cotton yarn, etc., and this year also launched special hemp yarns such as color spinning yarn. It has more than 20 years of production experience in the industry. Layer feedback, reducing quality problems and improving production efficiency.
