• ABSTRACT Hydrophobic fibers and fibrous structures having durable antistatic property and a process for producing such hydrophobic fibers and fibrous structures also are provided, by utilizing the above antistatic agent.
• the present invention relates to a novel antistatic agent soluble in organic solvent which can afford durable antistatic property, highly resistant to washing and dry cleaning, to hydrophobic fibers made of such polymers as polyester, polyacrylic, polyamide, polyvinylchloride, polyethylene and polypropylene polymers as well as fibrous structures such as cloth and knit fabrics made of such fibers, if applied to those fibers of fibrous structures in an organic solvent system.
• the present invention relates to hydrophobic fibers and fibrous structures having durable antistatic property and a method for producing such fibers and fibrous structures.
• Hydrophobic fibers and fibrous structures made of such fibers as mentioned above have excellent properties such as toughness and chemical resistance, but, as they are hydrophobic, they have great volume specific resistance and, therefore. they tend to produce a remarkable static electrification phenomenon even by a slight friction, thus causing various electrostatic faults.
• Such faults will not only hinder a normal operation of the process steps for producing textile goods from textile fibers, for example, drawing and twisting, winding, warping, knitting and weaving, sewing, etc., but also cause lowering of product qualities or various troubles such as stains on products due to dust absorption and unpleasant feelings to human bodies.
• the former method has disadvantages such as the low dispersibility of the antistatic agent is liable to cause breaking of yarns and occurence of knotted yarns during melt spinning or lowering of qualities such as reduction of strength and elasticity. Further, due to thermal deterioration caused in melt spinning, dispersion into the coagulating bath in wet spinning, etc., only special kinds of antistatic agent can be used.
• the latter method is a temporary antistatic treatment method, in which, since the antistatic agent is stripped off by washing, the antistatic effect is gradually lowered or completely lost, which has not only the disadvantage of hurting the feeling of fibrous structures, but also has a greater disadvantage of not having a durable antistatic effect.
