Static control

Polyquatemium-11 is the copolymer of A/-vinylpyrrohdinone and dimethyl-arninoethyl methacylate quatemized with dimethylsulfate (20). It is used widely but provides Htde hold to the hair. Its primary advantage is its abiUty to improve the ease of wet combing and control static while giving a light set hold. 

Humidification. Adding moisture to air has long been used to control static and to help dissipate static electricity in textile mills (see A IR conditioning). Moisture does not improve the electrical conductivity of the air, but it increases the electrical conductivity of materials absorbing moisture. 

Antistatic Material that minimizes static charge generation, provides controlled static charge dissipation, or both.

Fibers emerging from the spinneret are cooled under controlled conditions, passing over guides and rollers to a take-up spool or bobbin. Often a finish is applied before windup to control static electricity and friction (Stevens 1993). Large-scale production machinery produces fiber at a rate of thousands of feet a minute. A schematic diagram of a melt-spinning apparatus is drawn in Figure 8-10.

Various industries make efforts to introduce static control to workplace, products and packaging. As many as 10% of the failures of electronic equipment are related to static electricity. To control static electricity in the work place, many products should be conductive (coatings, mats, bench tops, etc.). Packaging has been developed using conductive fillers. This creates new opportunities for manufacturers of products and fillers. 

The viscosity of this formulation can be reduced by the addition of ethanol if desired. Fabric softeners made with an Accosoft product are non-yellowing, control static and maintain rewet properties of the fabric.
