Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.

This method not only prevents fraying but also produces a clean, professional finish, essential for woven and knit fabrics. The capability to sew different types of stitches, including rolled hems and flatlock seams, further increases the versatility of these machines, making them suitable for a wide range of sewing applications, from fashion design to home decor.


  • Understanding the Price of Single Needle Quilting Machines


  • These machines can handle various types of polypropylene bags, from simple to complex designs. Whether it’s a standard gusseted bag or a custom-printed version, the flexibility provided by PP bag silai machines makes them an asset in any manufacturing setting.


  • Sewing with heavy canvas can pose some challenges due to its thickness and texture. The key is to use the right tools and techniques. First and foremost, a heavy-duty sewing machine is essential. Standard machines may struggle to handle the thickness. Look for machines that offer powerful motors and the ability to adjust presser foot pressure for optimal fabric feed.


  • Several places offer sales on 5% thread overlockers. Here are a few options for finding the best prices


  • The Versatility of Zig Zag Embroidery Machines


  • One of the primary advantages of a twin needle sewing machine is its versatility. With the capability to sew two parallel lines simultaneously, this machine can produce a variety of finishes, such as hems, pintucks, and decorative topstitching. You can work with different fabrics, from knits to woven materials, opening up a whole new world of possibilities for your sewing projects.


  • If you have decided to buy a heavy-duty sewing machine, make sure you understand the buying elements you should consider to make the right choice. With the right buying tips, you will buy a modern sewing machine that will suit your needs. On the other hand, when buying it for the first time, ensure you research and know its benefits and how they work. Here are the benefits of buying a heavy-duty sewing machine.

  • In addition to its power and durability, a heavy-duty leather sewing machine also offers a number of specialized features that make working with leather easier and more efficient. These machines often come with adjustable presser feet, walking feet, and feed dogs that are specifically designed to handle the unique characteristics of leather. This ensures that the material is fed through the machine smoothly and evenly, resulting in clean, professional-looking stitches every time.

  • Lock stitch is a sewing technique that involves interlocking two threads—one from the needle and the other from the bobbin—to create a strong seam. This method is particularly advantageous for securing the seams of jumbo bags because it provides a tight, secure closure that can withstand significant tension and pressure. Unlike other stitching methods, lock stitch produces a consistent and uniform seam, reducing the likelihood of bag failure due to seam separation.


  • Industrial sewing machines can use a lot of energy, especially computerized ones. Select sewing machines that won't overload your circuits when using one in a residential setting. Industrial machines tend to require upwards of 430 watts per hour or more.Generally, people start running into problems when running multiple heavy-duty sewing machines on one power circuit or when using multiple machines off of a single power strip. Before setting up your sewing room, consider the wattage (stickers can be found on most machines) and check with your electrician to ensure you will not be blowing fuses or creating fire hazards. Do you live off the grid and use solar or battery to power your electronics? In that case, you may need to purchase an inverter to configure the right electrical current to avoid causing permanent damage to your motor and other electrical components inside your sewing machine.

  • Selecting the correct needle plays a significant role in the stitching process. For leather, a needle with a triangular or chisel point is recommended. This design allows for easier penetration through tough leather fibers. Additionally, the size of the needle should correspond to the weight of the leather being used. A heavier needle (e.g., sizes 18-22) is suitable for thick leather, while a lighter needle (sizes 14-16) works better for thinner varieties.


  • A walking foot is a type of presser foot that features an additional set of feeding mechanisms on top of the fabric. Unlike standard presser feet that rely solely on the machine’s feed dogs to move the fabric beneath the needle, the walking foot grips the fabric from above and moves it in sync with the feed dogs below. This dual feeding action prevents slippage and ensures that all layers of fabric are fed evenly through the machine, which is particularly helpful when sewing thick or textured materials.


  • II. Choosing the Right Heavy Duty Sewing Machine
