A Yarn Characterisation Unit: The staple yarn characterisation unit measures the diameter and mass irregularity of cotton/jute yarns along with the yarn faults, hairiness indices, hair counts, U%, CV% in a single run by dual sensing options like image processing and optical sensing. These measurements are useful to predict the final appearance and feel of fabrics in general and export oriented quality checking in particular.

Flexural Rigidity Tester

Fabric Insulation Tester

The fabric bending stiffness tester : The complete behaviour of fabric bending stiffness can be determined dynamically in a simpler, mechanized and computerized way. This tester is suitable for all types of textile fabrics ranging from thin apparel to thick laminated nonwoven including semi- rigid coated fabrics. The dynamic bending stiffness will express the idea of drapability and creasing behaviour simultaneously.

The fabric electrical insulation tester: It can measure fabric electrical insulation property. This tester is suitable for almost all types of textile fabrics. The measurement of electrical insulation will help to design technical textiles used for flooring of high voltage instrument room, jackets used by technicians handling high voltage devices, gloves etc.
