The norms are given for different types of weaving machines, such as shuttle looms, rapier looms, air-jet looms and water-jet looms. The norms are also given for different types of fabrics, such as plain weave, twill weave, satin weave and dobby weave. The norms are expressed in terms of ranges or averages, depending on the variability of the data. The norms are updated periodically based on the feedback from the industry and the latest technological developments.
The norms for weaving are useful for the textile manufacturers to benchmark their performance against the industry standards and to identify the areas of improvement. The norms also help in reducing the production cost, improving the quality and increasing the productivity of weaving machines. The norms can be accessed by purchasing the publication from Sitra or by downloading it from their website.
Sitra also offers other services to the weaving and knitting industry, such as quality audit, machinery audit, defect analysis, training and consultancy. Sitra has a well-equipped weaving and knitting lab with various machines for sample development and testing. Sitra also conducts research and development projects on various topics related to weaving and knitting, such as fabric engineering, fabric properties, fabric defects, fabric design and fabric processing.
