Conclusion

In addition to functional advantages, the zigzag foot also opens the door for creativity. Crafters and sewists can explore various decorative stitch patterns that can transform a simple project into a work of art. By altering the width and length of the zigzag stitch, sewists can create unique textures, motifs, or even appliqué designs that add personalized touches to their work. The ability to customize projects in such a way allows for endless possibilities, fueling the imagination of those who wield a sewing machine.

Finally, a regular sewing machine will be easier to operate, compared to a heavy-duty machine. For example, they will tend to be slower, making them easier to control. In addition, threading a heavy-duty machine might be slightly more difficult. Also, most heavy-duty machines don’t have a plastic casing around the engine. This will prevent it from overheating. However, the more frequently you use a heavy-duty sewing machine, the easier it will be for you to adjust to these operational differences. 

The origins of shoe manufacturing date back centuries, where artisans skillfully crafted footwear by hand. This traditional approach, while precise, was time-consuming and limited in scalability. The introduction of the sewing machine in the 19th century marked the beginning of a significant transformation in the footwear industry. However, it wasn’t until the late 20th century that automatic shoe sewing machines emerged, integrating advanced technologies that would redefine production capabilities.

TiO₂ possesses different qualities depending on whether it is produced as a pigment or a nanomaterial. Both forms are tasteless, odourless and insoluble.

All About Titanium Dioxide Pigment

Titanium dioxide (TiO2) is a chemically inert inorganic compound and an insoluble white solid that occurs naturally in several minerals, including rutile, anatase, and brookite. It is created synthetically from the mineral ilmenite. It is an insoluble white solid. Anatase, when compared to brookite and routine, has the most industrial applications, but it is the most toxic form of TiO2.

It is an anatase titanium dioxide pigment produced by a special process from sulfuric acid. Widely used in PVC pipes, interior coatings, industrial pigments, rubber, leather, polyolefins, Printing ink, plastic, paper, etc.

JECFA previously assessed titanium dioxide at its 13^th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
