It is well known that increasing the speed of the spinning frame can effectively reduce the production cost per ton of yarn and improve the economic benefits of enterprises. But when the speed of the ring spinning frame increased, the breakage rate increased significantly, causing production difficulties due to the insufficient strength of 48mm Double Strand Expanded Acrylic.
What causes 48mm Double Strand Expanded Acrylic to have low strength?
1. Short details, strong weak links
Because there are fewer fibers in the short detail section of 48mm Double Strand Expanded Acrylic, it can withstand less tension and is prone to breakage of 48mm Double Strand Expanded Acrylic, thus forming a strong weak ring.
Two long details, strong and weak rings
When long detail exists on 48mm Double Strand Expanded Acrylic, since the production conditions such as the weight of the wire coil and the spindle speed do not change, During the production process, the twist of the long details added to 48mm Double Strand Expanded Acrylic is the same as that of the normal 48mm Double Strand Expanded Acrylic, which results in a smaller actual twist at the details and a lower grip between the fibers. As the mass per unit length of 48mm Double Strand Expanded Acrylic decreases, the coefficient of centrifugal force of 48mm Double Strand Expanded Acrylic also decreases, the air ring becomes thinner and longer, and the posture of the wire ring on the collar changes. Poor operating stability when the strong force of 48mm Double Strand Expanded Acrylic cannot withstand tension fluctuation causes 48mm Double Strand Expanded Acrylic to break. Form a 48mm Double Strand Expanded Acrylic strong weak loop.
At the junction of coarse and detailed parts, there are strong and weak rings
If there are coarse details on 48mm Double Strand Expanded Acrylic, since the twist of 48mm Double Strand Expanded Acrylic tends to concentrate towards the details, then there is more twist at the details and more fiber at the coarse nodes with less twist. At the junction of the thick and thin strands, on the one hand, there is less twist, and on the other hand, there are relatively fewer fibers, and the cohesion between the fibers is poor. 48mm Double Strand Expanded Acrylic is prone to break here, thus forming a strong weak loop.
4. Weak twist point, strong weak ring
Sometimes on 48mm Double Strand Expanded Acrylic, weak twist points are formed due to spindle stuttering and other reasons. At these weak twist points, the interlocking force between the fibers is smaller and the strength is lower. 48mm Double Strand Expanded Acrylic breaks easily from here, thus forming a strong weak loop.
5. The strong and weak loops of the mixed coating points
If the 48mm Double Strand Expanded Acrylic is covered with impurities, the fiber structure at the point covered by the impurities is damaged, which often leads to problems such as fewer fibers, poor parallelism of fiber extension, and inconsistent twist angles at this point, resulting in a smaller breaking energy that this point can withstand. Also, since the 48mm Double Strand Expanded Acrylic at this junction is generally large in diameter, 48mm Double Strand Expanded Acrylic when passing through the wire coil 48mm Double Strand Expanded Acrylic channel is often blocked, resulting in an instantaneous peak of winding tension. This causes 48mm Double Strand Expanded Acrylic to break, forming a strong weak loop.
There are many factors that affect the weak ring of fine yarn strength. To effectively reduce the breakage of fine yarn, it is necessary to seek the most fundamental cause of the weak ring of fine yarn strength and eliminate the factors that form the weak ring of fine yarn strength from the source
