In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.

3. Versatility Besides garment making, double needle sewing machines are also employed in home décor projects, quilting, and leatherwork. Their adaptability make them a valuable addition to any sewing setup.
At the core of the double needle chain stitch sewing machine lies its unique threading system. Unlike conventional sewing machines that use a single needle and bobbin mechanism, the double needle machine operates with two needles threaded simultaneously. These needles penetrate the fabric and form a chain stitch, which is a type of stitch characterized by its interlocking loops. The two needles work in tandem to create parallel rows of stitching, resulting in a strong seam that can withstand stress and strain.

Overlock chain stitching is an invaluable technique in the world of sewing, providing a robust, flexible finish to a variety of textiles. Its efficiency in seam construction and its ability to prevent fraying make it a staple in both professional and home sewing environments.
