2. Material handling plays a pivotal role in the spinning industry, influencing yarn quality significantly across various stages from processing to storage. Over here, we have delved into the critical effects of sliver handling on sliver and yarn, highlighting key factors that impact the final product.

3. Effect of Spring Load and Storage Time on U% Slide Title One of the crucial aspects affecting yarn quality is the spring load of sliver cans and the duration of storage. Yarn unevenness (U%) tends to increase when sliver cans have lower spring loads and are stored for longer periods. This phenomenon occurs due to the heightened probability of fiber leakage between adjacent sliver coils. orange - e86324 deep blue - 0a355c

4. Effect of Spring Load and Coil Position on Strength CV% Slide Title The strength coefficient of variation (CV%) in yarn is significantly influenced by the spring load of sliver cans and the position of the sliver coils within them. Older sliver cans with reduced spring stiffness often exhibit higher CV% in strength. This is primarily due to the deformation and stretching of sliver fibers within the can. orange - e86324 deep blue - 0a355c

5. Effect of Storage Time and Coil Position on Thin Places Slide Title Extended storage times of sliver cans also impact yarn quality, particularly in terms of introducing thin places. Thin places in yarn occur when there are irregularities in sliver structure, often caused by sliver splitting and stretching during processing stages such as drafting at the speed frame. orange - e86324 deep blue - 0a355c

6. Effect of Coil Position and Storage Time on U% Slide Title Similar to strength CV%, yarn unevenness (U%) is affected by the position of sliver coils within the can and the duration of storage. At higher storage times, particularly with bottom sliver coils, compression forces from the weight of upper layers and the spring mechanism can flatten the sliver. This flattening process, coupled with stretching during subsequent processing, contributes to an elevated U% in the yarn. orange - e86324 deep blue - 0a355c
