Spincoil Technology achieves excellent Antistatic Properties
The antistatic performances of a fabric are extremely important in Protective Garments aimed at dissolving electrostatic discharges, which could cause fires, but they are equally crucial in Garment studied for the protection of process and products (cleanrooms).
The innovative SPINCOIL technology was born of hard studying and several prototypes realized by Argar S.r.l. in order to obtain excellent antistatic properties through continuous yarn containing conductive fibers, which guarantees outstanding performances of electrostatic charge dispersion even after several washing and drying cycles.
The production and finishing methods mostly used to get antistatic properties of fabrics are the use of discontinuous yarn with inherent antistatic fibers or antistatic finishing processes.
Antistatic finishing processes have a limited lifespan and low resistance to washing cycles. The use of discontinuous yarn with inherent antistatic fibers implies serious risks to maintain the antistatic properties because of antistatic fiber dispersion. This is particularly experienced in knitted fabrics which must be sheared (such as fleeces and sweaters), because shearing operation cuts and brakes the discontinuous antistatic fibers, thus degrading or even dissolving the antistatic properties.
None of the two methods was judged adequately trustable by Argar Technology.
Hence the idea of SPINCOIL technology was conceived, using continuous yarn including antistatic fiber. Over the years a full range of Protective Knitted Fabrics Tes-firESD®, Hvis-Tes® ESD and Shield-Tes® were developed in several knits like jersey, pique, sweater, rib fabric and fleece. Some of these knitted fabrics comply with EN1149-5, showing even after 25 or 50 washing cycles almost unchanged antistatic properties.
The R&D Dept. of Argar Srl is continually improving its products and studying innovative projects for new articles and new technologies.
