Frequently Asked Questions | FAQs

What is the importance of weft insertion by air jet?

Weft insertion by air jet is an important method of inserting weft yarns into woven fabrics. In this method, the weft yarn is propelled through the shed by a high-speed jet of air. The importance of weft insertion by air jet lies in its ability to produce high-quality, high-speed, and efficient weaving.
One of the key advantages of air-jet weft insertion is its high speed. Air-jet weaving machines can operate at speeds of up to 1500 picks per minute, making it a highly efficient method of production. This high speed is particularly important for manufacturers who need to produce large volumes of fabric in a short amount of time.
Another advantage of air-jet weft insertion is its ability to produce high-quality fabrics with uniform and consistent yarn insertion. The air-jet technology ensures that the yarn is inserted into the fabric with precision and accuracy, resulting in a high-quality finished product. Additionally, air-jet weft insertion can be used to weave a wide range of yarns, from fine and delicate to heavy and robust, making it a versatile method of production.
Finally, air-jet weft insertion is also an environmentally friendly method of production, as it requires less energy and water compared to other methods of weaving. This makes it a sustainable and cost-effective option for manufacturers looking to reduce their environmental impact and save on production costs.
