Soil Release finish:

What is Soil Release Finish?

Durable press fabrics containing polyester fibres are known to show tendency to retain stains and also attract soil from the wash liquor during washing. This is due to hydrophobic nature of these fabrics. Various soil-release agents have been developed. These are described as durable film forming polymers containing polymer groups which are capable of hydrogen bonding with water. These finishes are applied by a pad-cure process along with the resin.

Antistatic Finishing:

During spinning, weaving and finishing, textile fibres, yarns and fabrics are subjected to friction. Static electricity is
thus generated on the fibre. Polyester fibre has low conduction hence it accumulates static electricity. Static electricity gives rise to a number of problems. For instance, the operator at the delivery end of a stenter may get electric shocks because of static electricity. Garments made of polyester fibres attract soil during normal wear and also have a tendency to cling to the body of the wearer.

Non-durable antistatic agents are usually hygroscopic surface-active materials, closely allied in composi6on to softeners and wetting agents. A permanent antistatic finish can be given by using a combination of a cationic and an anionic compound.

Cationic quaternary ammonium compound - 3-4%

Acetic acid (30%) - 0.5-1 cc/l

Treat the fabric with the above composition for 10-20 min at 70'C (in a jigger). Then add (anionic alkyl sulphate) - 1.6-2.2%

Continue treatment for another 10-20 min. Dry and cure if required.
