Heald Wires are an essential component that are used in the textile industry for the purpose of weaving. They help in guiding the warp threads for weaving. These wires play an important part in weaving as they make the process of weaving easy and produce better quality textiles. This is because they enable proper orientation of warp yarns and thus prevent any weaving errors.
To maintain consistent standards in terms of quality, performance and safety, the Bureau of Indian Standards has established certain guidelines as per IS 8565: 1977. The standard sets out the specifications of materials, dimensions, and mechanical strength to ensure that the wire does not break down under constant stress while weaving. The Manufacturers must obtain BIS certification to enhance trust in the Indian textile industry.
What is IS 8565: 1977
This is the Indian Standard for Heald Wires used in the textile industry, which outlines requirements for workmanship, dimensions and mechanical properties of the product. This standard is set by the BIS (Bureau of Indian Standards) to ensure that product quality and safety are met, and the wires are
- Manufactured with precise dimensions for accurate guidance during weaving
- Designed to ensure smooth weaving performance
- Tested for mechanical strength to withstand continuous loom operations
- Inspected for surface finish and defects such as cracks
