Yarns suitable for durable light shade cotton/nylon clothing fabrics containing carbon doped antistatic fibers

Yarns which are suitable for use in the warp of durable cotton/nylon clothing fabrics dyed in light shades with permanent antistatic properties are disclosed.

ComforSpin-a new spinning process

In the ComforSpin process from Rieter, an intermediate zone is inserted between the draft and yarn formation. The ready drafted fibre structure is condensed laterally by means of aerodynamic forces in this intermediate zone. The fibre structure which is fed to the spinning triangle is so narrow that the spinning triangle becomes so small ..

Assessment of interlaced yarns by means of computeraided image analysis

The development of new biodegradable films based on blends of biotransformed cellulose and starch is presented. A preparation method for blended films using alkaline solutions of a mixture of biotransformed cellulose and starch is described. Their mechanical properties, as well as their susceptibility to biodegradation, are also discussed
