Chemical Technology

Fabric Defect Analysis: Fabric samples are analyzed, reasons for occurrence of defects are identified and suggestions are given to rectify the defects. Defect cause analyses are done with respect to Yarn, Weaving and processing and garmenting

Certification of Cloth samples for Customs Dept: Certification of quality parameter mentioned in import /export documents

Performance and Testing of the Processing Chemicals: Performance testing of chemical samples are carried out for Processing units and chemical manufacturers. Tests are carried out by treating the fabric with chemicals and evaluating the properties of treated fabrics. All the tests are carried out in view of actual usages of particular chemical which helps in proper selection of chemical and costs comparison

Testing of Dyestuffs for exports: Dyestuff samples are tested against the quality standards of the manufacturers which forms the basis for importers decision

Preparation of composite soiled stripe: The stripe set is used for testing of washing machine performance evaluation. Stripe set are prepared as per IS 5785-1976. Stitched standard garment and dummy fabric are supplied for evaluation of washing machine performance

Consultancy

1. Mercerization is most important process for cotton fabric dyeing

In mercerization process cotton fabric is padded with 250 gm per liter caustic under tension on mercerization machine. This padded caustic is removed from the fabric in subsequent washing at mercerization machine. This removed caustic is re concentrated to required concentration and reused for mercerization.

Units having caustic recovery plant use about 6 to 8 kgs of fresh caustic per 100 kgs of cloth for mercerization. Units without caustic recovery plant use 20 to 25 kgs of caustic for same production. Unrecovered caustic is washed and cause heavy pollution of effluent.

Consultancy services are provided to industry for proper use and recovery of caustic soda in mercerization process. Production of caustic soda is power intensive. For production of each kgs of caustic almost 4 units electrical power is consumed.

2. Reduction of water consumption

Work is carried out for textile process houses. Water consumption of each processing machine is measured. Water flow and waste water quality is checked. The processing sequence used in each process is studied. Based on the observation made processing steps are reduced or water flow is controlled. Mills can save upto 25% water in processing by these studies besides effluents.

3. Problem specific consultation

Expert team undertakes study in detail on shop floor and implementable suggestions are given

Training of Young Industrialist and Technicians From Industry.
