long arm stitching

- Apparel Production The lock stitch is prevalent in finishing seams, hems, and securing fabric layers, providing a clean and professional look to garments.

In summary, the typical double needle sewing machine is a fantastic addition to any sewist’s toolkit, providing efficiency, versatility, and professional-quality results. Its ability to create two lines of stitching in a single pass not only saves time but enhances the aesthetic appeal of the finished product. Whether for commercial applications or personal projects, mastering the double needle technique can significantly elevate one’s sewing capabilities and creativity. As the sewing industry continues to evolve, the double needle sewing machine remains a trusty companion for those looking to push the boundaries of fabric artistry.

Sewing is a wonderful hobby that combines creativity with practicality. If you’ve recently acquired a sewing machine or are looking for simple projects to enhance your skills, there are plenty of easy sewing projects that can be tackled even by beginners. These projects not only provide an opportunity to practice sewing techniques but also result in functional items that you can use or gift. Here are a few easy sewing projects to consider.

Introduction

The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.

As an professional Lithopone factory, Jinan Hongquan Titanium Industry Co., Ltd is located in Jinan, a beautiful spring city. The company’s scientific research personnel sincerely cooperate with well-known domestic universities and various titanium dioxide production enterprises to study and produce active Lithopone with great concentration. Some of its products have been widely used in chemical, textile, paper, plastic, paint and other production fields.

In addition to its physical properties, titanium dioxide also has environmental benefits. As a non-toxic compound, it is safe to use in homes, offices and public places. Coatings formulated with titanium dioxide contain virtually no volatile organic compounds (VOCs), ensuring minimal impact on indoor air quality and human health. Additionally, due to their long-lasting nature, titanium dioxide-infused paints can help create a more sustainable environment by reducing waste and the need for frequent repainting.

For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.  

At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.
