Abstract: This paper discusses the water-repellent and anti-static finish of polyester fabrics and polyamide fabrics. The fabrics were finished by using antistatic agent DM-3724 and waterproof agent 9033 in one bath and the interplay between waterproof effect and antistatic effect was investigated. The test results show that the waterproof effect tends to be weak with the increase of dosage of antistatic agent, especially occurs in polyester fabrics; on the other hand, with the increase of dosage of waterproof agent, the antistatic effect of polyester fabrics gradually improved, while the polyamide fabrics was opposite. Water-repellent and antistatic one-bath process could endow the fabrics with good waterproof effect and antistatic effect, through adjusting dosage of the agents.

Key words: water-repellent finish; antistatic finish; polyester fabric; polyamide fabric
