SITRA’s activities since its inception was centred around addressing the needs of the spinning mills which on areas like testing of fibre and yarn, labour and machine productivity, cost control, bench-marking of operational and technical parameters, training, etc. Accordingly, the department of Mechanical Processing, as this division was originally referred to, was established along with the Physics division in the year 1957. Later this division was bifurcated into two specialized division namely the Spinning division and the weaving and knitting division.

The Spinning division with a team of experienced technocrats having enormous experience of domestic and overseas units offers value added services such as Quality audit, Machinery audit, Quality oriented machinery audit for specific quality issues, Training and need based consultancy services.

The pilot mill which operates a part of this division houses all industrial model machinery to replicate a spinning mill for providing solutions on areas relating to product development and processing of range of fibres from cotton to unconventional natural fibres like Hemp, Flax, Banana, Milkweed fibre, recycled cotton and blends to help in evaluation of yarn quality and optimization of process parameters. Ti would help mills seeking the service to scale up similar processes in their mills.

Spinning division also carries out various R&D activities in areas relating to machinery modification for yarn quality improvement, evaluating fibre characteristics of the cotton varieties towards projecting their influence on yarn quality, relevance and impact of modernization in the spinning industry, etc.
