Pigments absorb specific colors due to their molecular structure and the way they interact with light. When white light strikes a pigment, the molecules absorb certain wavelengths (colors) of light while reflecting others. This absorption occurs because the energy from specific wavelengths matches the energy gap between the electrons' ground state and an excited state in the pigment molecule. Electrons absorb this energy and jump to higher energy levels, leaving the other wavelengths to be scattered or reflected. The color we perceive is primarily the wavelengths that are not absorbed but instead are reflected back to our eyes. For instance, chlorophyll appears green because it absorbs red and blue light strongly but reflects green wavelengths. Different pigments have distinct molecular structures, leading to different energy gaps and, consequently, varying absorption spectra. Therefore, each pigment absorbs specific colors based on its unique molecular makeup and the energy requirements of its electrons.
To make medical grade cannabis oil, one must start with high-quality, pesticide-free cannabis. Decarboxylation is the initial important step, which involves heating the cannabis at about 220°F for 30-45 minutes to activate THC and CBD. Next, the decarboxylated cannabis is mixed with a solvent (commonly ethanol or food-grade oils) to extract the cannabinoids. The mixture is then strained to remove plant material, and the solvent is evaporated in a well-ventilated area using low heat under a vacuum to create a potent oil. It's crucial to know the laws in your region regarding cannabis use and extraction. Precision, cleanliness, and safety are key to producing medical-grade oil, including using lab-tested starting material and possibly testing the final product for potency and purity.
PVC-free heat transfer materials offer an eco-friendly alternative to traditional vinyl transfers. These materials are based on polyurethane (PU), which provides similar durability and flexibility without using the chlorine found in PVC, making them less harmful to the environment. The absence of PVC not only reduces toxic releases during manufacturing but also during disposal or recycling. PU-based transfers are suitable for a wide range of textiles and are popular in the production of sports apparel, children's clothing, and eco-conscious fashion brands. When choosing PVC-free heat transfer materials, it's essential to consider their compatibility with the fabric, durability, and the environmental standards they meet. Many suppliers now offer these materials with certifications to attest to their eco-friendliness. Opting for PVC-free heat transfers is a step toward sustainable production practices in the textile industry.
