Handheld sewing machines are incredibly compact, allowing you to take them anywhere. They are ideal for those with limited workspace or those who enjoy sewing while traveling.

5. Walking Foot Mechanism A walking foot is a great addition for sewing leather as it helps to evenly feed the material through the machine, preventing slipping and ensuring neat seams.

The Importance of Choosing Strong Sewing Machine Needles

While the long arm double needle chain stitch technique offers many benefits, it is not without its challenges. Operators need to have specific training to handle these machines effectively, as improper use can lead to thread tension issues or uneven stitching. Additionally, not all fabrics are suitable for this stitching method; selecting the right fabric composition is essential to achieving the desired results.

In addition to its various stitch options, an overlock serger sewing machine also has the ability to adjust thread tension, stitch length, and stitch width. This level of customization allows you to achieve the perfect stitch for any fabric or project you are working on. Additionally, many modern sergers come equipped with automatic threading features, making it easier than ever to set up your machine and start sewing.

Historical references

Titanium dioxide is predominantly used as a pigment in products such as paints, coatings, plastics, food, cosmetics, and paper. The ability of TiO2 to scatter light and provide a white color makes it an essential ingredient in achieving high-quality finishes in these applications. However, the production of titanium dioxide can be complex and costly, given that it involves raw materials such as ilmenite and rutile, as well as advanced processing technologies. Manufacturers are continuously striving to optimize costs without compromising quality, making the search for affordable suppliers a top priority for many businesses.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.

We've used titanium dioxide safely for decades. However, recently its safety was called into question. 
 
At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
 
It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects. 
 
A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
 
In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.
