Frequently Asked Questions | FAQs
What are types of weft insertion?
There are three main types of weft insertion used in weaving:
1)Plain weave: In plain weave, the weft yarns pass over one warp yarn and then under the next, alternating in this way across the width of the fabric. This produces a strong, even fabric that is commonly used in many applications.
2)Twill weave: In twill weave, the weft yarns pass over two or more warp yarns, and then under one or more warp yarns, creating a diagonal pattern on the fabric. This type of weave is often used for fabrics that require more drape or flexibility, such as denim.
3)Satin weave: In satin weave, the weft yarns pass over several warp yarns before going under one, producing a smooth, lustrous surface on the fabric. Satin weaves are often used in high-end fashion and home décor applications.
Which loom has a high weft insertion rate?
Air-jet looms have a high weft insertion rate compared to other types of looms. These looms use compressed air to shoot the weft yarn through the shed (the opening between the warp yarns) at high speeds, resulting in fast and efficient weft insertion. Air-jet looms can produce high-quality fabrics with a wide range of materials and are commonly used in textile production for their speed and efficiency. However, they may require more maintenance than other loom types due to their complex technology
