The count in yarn refers to a standard number denoting the thickness or fineness of the yarn. It is an indicator of how many length units of yarn weigh one unit of mass. For instance, in the cotton count system (Ne), a higher number means a finer yarn, as it denotes more length per unit weight (e.g., Ne 30 means 30 hanks of yarn each of 840 yards weigh 1 pound). Different materials might use different systems, such as the metric count (Nm) for linen, wool, and synthetic fibers, highlighting the meters per gram. Understanding yarn count is crucial for selecting the right yarn for specific projects, affecting the texture, drape, and overall outcome of the fabric.
No, PLA (Polylactic Acid) is not polypropylene plastic. PLA is a biodegradable and bioactive thermoplastic polyester derived mainly from renewable resources like corn starch or sugar cane. In contrast, polypropylene, a petroleum-derived plastic, is a type of thermoplastic polymer resin known for its toughness and flexibility. While both are widely used in the packaging industry, their origin and environmental impact differ significantly. PLA is applauded for its biodegradability, making it a preferred choice in applications aimed at reducing plastic waste and promoting sustainability. Polypropylene, though recyclable, is not biodegradable and poses more of a challenge in terms of environmental sustainability.
For repairing a broken walnut gun stock, a commonly recommended adhesive is a two-part epoxy resin. This choice is due to its high strength, ability to fill gaps, and compatibility with wood. It provides a durable bond that can handle the stresses typically exerted on a gun stock. Before applying, ensure the broken surfaces are clean and fit together well. Lightly sanding the area can improve adhesion. Apply the epoxy according to the manufacturer's instructions, clamp the pieces in place, and allow it to cure fully, typically 24 hours. For best results, consider reinforcing the repair with dowels or brass pins, especially in areas subjected to high stress.
