The impact of automatic machine sewing extends beyond the production line; it also reshapes the workforce dynamics within the industry. While automation may lead to a reduction in the number of manual sewing jobs, it simultaneously creates new opportunities in machine operation, programming, and maintenance. Workers are required to adapt to these changes by acquiring new skills related to operating sophisticated machinery and understanding digital design software. As a consequence, the industry sees a shift toward a more technologically savvy workforce, fostering a culture of continuous learning and adaptation.

Popular Sewing Machines for Tent Making

The handheld bag closer is a compact and portable sealing machine that provides a quick and effective means of closing bags. Its design typically features a user-friendly interface, allowing operators to seal bags with minimal training or skill. Most models are equipped with an electric motor, heat sealer, or stitching mechanism, enabling them to accommodate various materials, including plastic, paper, and fabric.

Leatherworking, often viewed as a meticulous and intricate craft, can sometimes be daunting for beginners. Traditional sewing machines can be heavy, cumbersome, and often require extensive setup. This is where handheld leather sewing machines shine. Their lightweight design and user-friendly interface simplify the sewing process, allowing users to get started right away without the need for complicated setup or bulky equipment.

The aim of this work was to examine particularly the Degussa P25 titanium dioxide nanoparticles (P25TiO₂NPs) because they are among the most employed ones in cosmetics. In fact, all kinds of titanium dioxide nanoparticles (TiO₂NPs) have gained widespread commercialization over recent decades. This white pigment (TiO₂NPs) is used in a broad range of applications, including food, personal care products (toothpaste, lotions, sunscreens, face creams), drugs, plastics, ceramics, and paints. The original source is abundant in Earth as a chemically inert amphoteric oxide, which is thermally stable, corrosion-resistant, and water-insoluble. This oxide is found in three different forms: rutile (the most stable and substantial form), brookite (rhombohedral), and anatase (tetragonal as rutile), of these, both rutile and anatase are of significant commercial importance in a wide range of applications [3]. Additionally, the nano-sized oxide exhibits interesting physical properties, one of them is the ability to act as semiconducting material under UV exposure. In fact, TiO₂NPs are the most well-known and useful photocatalytic material, because of their relatively low price and photo-stability [4]. Although, this photoactivity could also cause undesired molecular damage in biological tissues and needs to be urgently assessed, due to their worldwide use. However, not all nanosized titanium dioxide have the same behavior. In 2007, Rampaul A and Parkin I questioned: “whether the anatase/rutile crystal form of titanium dioxide with an organosilane or dimethicone coat, a common titania type identified in sunscreens, is appropriate to use in sunscreen lotions” [5]. They also suggested that with further study, other types of functionalized titanium dioxide could potentially be safer alternatives. Later, Damiani found that the anatase form of TiO₂NPs was the more photoactive one, and stated that it should be avoided for sunscreen formulations, in agreement with Barker and Branch (2008) [6,7].
