When it comes to leatherwork, choosing the right materials is crucial for achieving both aesthetics and longevity. One of the most vital components in any leather project is the thread used for stitching. Among the various options available, thick thread has gained popularity among artisans and hobbyists alike. This article explores the benefits of using thick threads for sewing leather and provides insights into how they elevate the quality of leatherworking projects.

A lockstitch sewing machine creates a stitch by interlocking a top thread and a bobbin thread. The top thread, which is fed from a spool, is threaded through a needle, while the bobbin thread is wound into a small spool that sits underneath the needle plate. As the needle penetrates the fabric, it carries the top thread down, creating a loop which the bobbin thread catches. As the needle ascends, the two threads interlock, forming a secure stitch. This simple yet effective mechanism is what makes lockstitch machines popular and indispensable in numerous sewing applications.

What if you need a machine that is more industrial but you don’t have the space or the budget for a true industrial machine?

Relative Density Among commonly used white pigments, lithopone has the smallest relative density. Among white pigments of the same mass, titanium dioxide has the largest surface area and the highest pigment volume.

In conclusion, the CaCO3 and TiO2 factory plays a vital role in supporting industrial and economic development by producing high-quality materials for a wide range of applications. The continued growth of industries such as construction, agriculture, and manufacturing relies on the availability of CaCO3 and TiO2 from reliable sources like the factory. As technology advances and demand increases, the factory will continue to innovate and expand its production capacity to meet the needs of a rapidly changing world.

There are numerous manufacturers of titanium dioxide; the largest include Delaware-based Chemours (a spin-off of DuPont Chemical), Texas-based Kronos, and China-based Lomon Billions Group, all of which manufacture pigments for use in products like paints, coatings, and plastics. UK-based Venator is a major supplier of titanium dioxide used in food and cosmetics, along with paints, paper, plastic, and more. As a pigment, it is called Pigment White 6 (PW6), titanium white, or CI 77891. As a food additive, it is known as E171.

Titanium dioxide, a versatile and widely used material, finds its application in various industries including the rubber industry. This white pigment is known for its excellent UV resistance, durability, and opacity, making it an ideal choice for enhancing the properties of rubber products.

In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2.  With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”

In summary, the Food Directorate's position is that there is no conclusive scientific evidence that the food additive TiO₂ is a concern for human health. This is based on a review of the available scientific data relevant to food uses of TiO₂. However, we will continue to monitor the emerging science on the safety of TiO₂ as a food additive and may revisit our position if new scientific information becomes available.
