What is the main purpose of winding?
Objectives of winding: Winding process has some objectives which are given as below: To transfer yarn from spinning bobbin package to a convenient yarn package. To improve the quality of yarn. To get suitable yarn package.
What is the role of yarn tensioning in winding process?
In winding process; yarns are transferred from one package to another. During winding process; the tension of the yarns should be in controlled, otherwise yarn breakage will be increased for high tension or low tension will hampered the winding operation. So, tensioning device plays an important role in winding.
Why is a yarn guide important for weaving operations?
Yarn guides are required to perform the winding or unwinding process properly. In every operation where yarns are transferred from one package to another, yarn guides are required there. Yarn guides are used during winding, warping, beaming and weaving process. … Yarn cleaner also placed along the yarn path.
What is winding in weaving?
WINDING. Winding consists in winding the yarn on a tube. The weaving cones are prepared for the warp (vertical threads) in a cylindrical form, all of the exact same length to avoid waste. For the warp to be produced conical bobbins are made so that the yarn can slide on the frame without problems.
What is the operation in the winding process?
The winding process consists of transferring the yarn from a starting bobbin or spool to a final package, that is a rigid cone wrapped in crossed coils. This process allows the yarn to be packaged in a format that is more suitable for subsequent processing, ie packages of considerable size and easy to unravel.
What is tension in textile?
Tension. Tension is the force that stretches a fabric. Some fabrics, such as acrylic, have a high tensile strength making them strong and hard to tear, whereas chiffon is an example of a fabric with low tensile strength.
Are the yarn preparation processed for weaving?
The processing steps are as follows: Winding and clearing • Weft winding • Warping • Sizing and other applications • Entering and knotting • Loom operation • Finishing • Inspection and measuring. The first five operations are those that prepare the yarns for weaving, the main theme of this lecture.
What is warp winding?
2010 3rd yearTextile Engineering, Wollo university (KIOT) Page 2 WARP WINDING Winding is the process of transferring yarns from ring, bobbin, hank etc into a suitable package. This makes using the yarn on subsequent machines both easier and more economical.
