What is piecing of yarn in textile spinning:


Spinning frame production means yarn production. 1 spinning frame has 80 to 100 spindles and it is not possible to give 100 percent production in 100 spindles during production. Of these, production is stopped all the time due to the loose yarn in 2/4 spindles. A spinner should attach this loose yarn very quickly, i.e. spin the yarn. The sooner this yarn is peeled the higher the production efficiency will be. So a skilled spinner can help increase productivity. https://bdfabric.com/auto-doffing-in-textile-jute-spinning/

Definition of piecing of yarn:

A spinner uses a special method to attach the loose thread head and the edge of the sliver to the protruding needle of the drawing roller. This method of pairing is called Piecing of yarn. This is sometimes called splicing. https://bdfabric.com/jute-spinning-frame-and-its-objectives/

Description of what is piecing of yarn in textile spinning:

For various reasons, the spinning frame stopped when the yarn is turned on. This is called end breakage. The workers are given basic training on how to sew yarn. Workers who pass the initial training are employed as replacement workers. Only when a substitute worker can prove his skills and other qualifications will he be hired as a permanent spinner in Mills. The first thing to do is to hold the spindle’s rotating flyer abruptly by hand. It is very difficult for an ordinary worker to do this but it is very easy for a permanent spinner. In this case, the polished surface of the flyer’s drive tape heap slips, causing the flyer to stop in the spinner’s hand.

The spinner then inserts a specially made hook into the hole of the heap and pulls the head of the loose yarn with the help of the hook and lifts it through the heaping hole. And the sliver on the bottom of the drawing roller grabs the place of delivery in the form of thread and leaves the heap. The yarn is twisted and attached. This must be done at the time of pairing so that the feeding which was stopped due to stop motion must be started immediately, otherwise, the thread will not be attached. Here, with the sliver of the drafting zone, the end of the bobbin is twisted, twisted into a yarn, and production begins.
