In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”

The composition of lithopone underscores its superiority in specific applications. Ideally, prepared lithopone consists of 30 to 32 percent sulfide of zinc, and a negligible percentage of zinc oxide (1.5%), with the remaining majority being barium sulfate. These attributes render lithopone nearly comparable to the best grades of French process zinc oxide in terms of whiteness. Furthermore, its oil absorption, which sits between lead carbonate and zinc oxide, solidifies its position as a functional and efficient white pigment.

  • Compound feed and triple feed sewing machines offer unmatched precision and durability for heavy-duty sewing tasks.  Their advanced feeding mechanisms ensure consistent fabric movement and stitch quality, making them invaluable assets for industrial sewing operations.  Elevate your production capabilities—buy a compound feed sewing machine today and experience the difference it can make.

  • At its core, a walking foot machine is designed with a unique feeding mechanism that allows the presser foot to walk along with the fabric as it moves through the machine. This mechanism is particularly beneficial when working with multiple layers of thick materials such as leather, canvas, or upholstery fabrics, which can be challenging to sew with standard sewing machines. The walking foot evenly feeds the layers of fabric through the machine, preventing slippage and ensuring that all layers move at the same pace. This results in a more consistent stitch quality and minimizes the risk of puckering or distortion.


  • 4. Material Usage Waste generated during the overlocking process must also be factored into the overall cost. Efficient use of materials can help in minimizing waste and lowering costs.
