Inkjet printers are not typically designed for printing on PVC cards due to the rigid nature of the material and the specific ink requirements. PVC cards require special dye-sublimation or direct-to-card printing technologies for optimal results. However, some users have reported success with certain inkjet models like the Canon Pixma series, specifically the iP7220 or MG6420, by using third-party feeders and specialized inks that adhere better to non-porous surfaces. It's important to note that standard inkjet inks may not bind well to PVC, leading to smudging and poor durability. For professional-grade PVC card printing, dedicated card printers such as those from Zebra, Fargo, or Magicard are recommended. These printers use thermal transfer or dye-sublimation methods, ensuring high-quality prints that are scratch-resistant and long-lasting. If you're considering an inkjet option for occasional PVC card printing, make sure to test compatibility and print quality thoroughly before committing to bulk production.
Organic viscose yarn is a type of yarn produced from the cellulose of organic plants, such as bamboo, soy, or sugarcane, that are grown without the use of synthetic pesticides or fertilizers. The process of making viscose involves dissolving the plant cellulose in chemicals and spinning it into fibers, which are then turned into yarn. What sets organic viscose apart is its sourcing from certified organic crops, ensuring a lower environmental impact compared to conventional viscose. It combines the benefits of being eco-friendly with the softness, breathability, and absorbency of viscose, making it an appealing choice for eco-conscious consumers. However, it's important to note that the chemical process of producing viscose, even when organic, still raises environmental concerns. Consumers looking for eco-friendly textiles are encouraged to consider the full lifecycle impact of organic viscose and explore other sustainable options as well.
Polypropylene is well-regarded for its durability. As a thermoplastic polymer, it exhibits a high resistance to many chemical solvents, bases, and acids. Its fatigue resistance is one of its most notable attributes, making it ideal for products that undergo repeated flexing. Additionally, polypropylene has a good resistance to physical damage and environmental factors such as water and UV light, although prolonged exposure to UV can degrade it over time. It is used widely in packaging, textiles, automotive components, and consumer goods due to its robustness, flexibility, and versatility. However, its performance can be affected by extreme cold, where it becomes brittle.
