Applications of Covered Elastic Thread in Smocking
Smocking thread is widely used in the garment industry. It offers high production efficiency and a relatively competitive price compared with circular woven elastic. As a result, it can be used as an alternative to circular woven elastic in products that require lower load-bearing capacity, such as garment covers, hashtags, nametags, gloves, and face masks.
Thanks to its elasticity, covered elastic thread is also used to manufacture short socks, gloves, elastic bands, women’s underwear, and sewing threads for shirred garments. It is also suitable for various decorative accessories and packaging applications.
