|Stitching and Understanding of Thread|
Different applications require different types of thread. The way the thread is made has a significant impact on the way the thread behaves in stitching and the final product. The half a dozen common thread construction methods include:
Spun polyester threads are first spun from polyester fiber into one long single thread. Two or more of these single threads are twisted or plied together to form sewing thread. The number of threads plied together determines the size. Threads are often coated with a finish like hot wax or silicone to enhance the sewing performance. Spun polyester threads are known for superior strength and better sunlight and abrasion resistance compared to similar 100% cotton threads. The versatility of spun polyester allows it to be used to construct the sheerest of lingerie or the heaviest of denim. Spun polyester thread is the most commonly used thread globally.
Textured threads are constructed from long filaments of yarn like polyester that is bulked up by many different mechanical methods. Textured threads in the relaxed state have a good feel because of the bulking.
Core threads are constructed from a wide range of fibers and materials. A staple fiber is spun around a bundle of continuous filament. A cross-section would look a bit like a doughnut. Core threads are available in a wide range of sizes and are used in everything from fine blouses to heavy coveralls. Core threads are recommended for automatic sewing machines. The surface fibers retain the thread lubricant, which helps the thread provide exceptional sewing performance, resulting in high productivity and low down time on high-speed automatic multi-directional lockstitch machines.
One example has cotton fiber wrapped around a polyester core. This thread provides the feel and appearance of cotton with the strength of the polyester core. Core threads are widely used for sewing, from delicate blouses to heavy clothes. The cotton wrapped polyester core thread is often used in jeans or chinos.
Why Core Spun with Cotton Wrap?
Core Spun threads are made from High Tenacity Polyester Filament covered with Cotton during spinning. Special treatment process gives it an extremely smooth surface & bright luster. Its key benefits are:
