The core spandex is covered to a fantastic extent and the core exposure is a lot less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically around the core filaments, the elasticity on the wrapped yarn is very well well balanced and can usually be processed inside the later on course of action without the need of shaping treatment, however the processing price of double wrapped yarn is larger. It is principally employed for elastic fabrics for example leg guards, elastic belts, sock openings and tights.

The compressed air sorts rhythmic community factors, resulting in a cloth that feels extremely delicate and smooth.
Solitary covered yarn involves wrapping an individual layer of masking yarn around a core yarn, commonly spandex. This process leads to a yarn that gives average elasticity and strength, which makes it suited to a variety of programs.
Herng Fa's Superior technological know-how enables us to personalize the most crucial and matching yarns Based on your distinct prerequisites, ensuring a tailor-made Option for your textile wants.

The elongation on the SCY can also be mostly determined by the efficiency in the spandex core yarn twisting an excessive amount of, the outer layer of fibre wrapped as well closely, and the elastic effect of your spandex yarn can’t give a fantastic effectiveness so the elongation decreases.
Herng Fa's system is particularly notable for its versatility, since the matching yarn and The 2 most important yarns may be adjusted In keeping with precise customer specifications.
