Synthetic fiber antistatic treatment

Polymer films can be made antistatic with a-sulfonated fatty acid salts and esters [94]. For example, an antistatic additive for polypropylene manufacture can be prepared from potassium methyl a-sulfopalmitate, styrene oligomer, and 2-propanol [95]. The treatment of synthetic fibers and fabrics with a-sulfo-... 

Antistatic agent for treatment of acryl-based synthetic fibers. 

Synthetic fibers do not contain natural impurities although there are added impurities such as sizing materials and oil stains. Therefore, their pretreatment process is simpler than other natural fibers. However, synthetic fibers such as polyester and acrylic have poor wettability, dyeability, and antistatic behavior. After plasma treatment, the fiber surface gets physically altered, and hydrophilic functional groups are introduced to the fiber surface, which improves the wettability of the fiber significantly. In recent years, many researchers have studied ways to modify polyester textile materials, and good results have been obtained (Morent et al., 2008). 

In using this new approach, conventional corona treatment is combined with injection in a reactive medium of microcapsules in aerosol form. Chemical nanotreatment or coating occurs when the aerosol condenses on the substrate at low temperature, resulting in a durable effect (most likely due to the formation of covalent bonds). An improved antistatic behavior is also obtained on textile substrates. Application is possible on both natural and synthetic fibers, as well as on thermosensitive hydrophobic substrates such as polypropylene and polyethylene.
