The reason for yarn drop in ring frame:
Table of Contents
Introduction:
Since there are various defects in the spinning frame during yarn production, it is normal for the product to be defective. However, care must be taken so that the amount of error is not excessive. To reduce this, proper raw materials should be well machined and hard supervised during production. During the preparation of the yarn, rings are available in the spinning frame as a byproduct of neutrophils, hard waste, invisible dirt, etc. Draft, twist, etc. are provided for making yarn in the ring-spinning frame which needs to be reduced and increased as required. https://bdfabric.com/building-motion-of-ring-frame/
The reason for yarn drop in ring frame:
This can happen in the ring frame if the almost parallel fibers or yarn buttons that have been delivered are not able to reach the bobbin, i.e. the yarn cannot be tangled in the bobbin. Rather it is a miracle or an unusual phenomenon not to drop the yarn. However, in the modern era, there are many high-quality ring fame and back processed matches whose rate of yarn drop in the ring-spinning frame is negligible. https://bdfabric.com/roller-clearer-of-ring-spinning-machine/
The reason for the yarn drop in the ring frame can be mainly divided into two parts.
1. Technological fault
2. Mechanical fault
1. yarn drop in ring frame-Technological fault:
# If the twist is not correct
If the yarn twist is more or less than required, the yarn drop rate increases.
# If the speed of the spindle is excessive
If the speed of the spindle is increased more than the quality of the yarn, then the rate of yarn drop increases.
# If the yarn tension is excessive
Increased yarn tension due to various technical reasons increases the rate of yarn drop.
# If the roller setting is not correct
The closer or wider the setting, the higher the yarn drop rate.
# If the draft is incorrect
Giving more or less break daft will increase the rate of yarn drop.
# If the diameter of the empty bobbin is not correct
If the diameter of the empty bobbin increases as compared to the requirement, the rate of yarn drop will increase.
#Roving Somewhere thick Somewhere thin
If there is an error in roving, the rate of yarn drop will increase.
# If the relative humidity is low or high
If the humidification system is not correct, the rate of yarn drop will increase.
2. Mechanical fault
# If the ring is defective.
# In case of an old or defective roller.
# If the roller cover is defective.
# If the traveler is broken.
# If the setting of the ring is not correct.
# If the spindle vibrates.
# If Bobin’s center isn’t right.
