Abstract: The fastness of dyeing of fabrics, also called color fastness, refers to the ability of colored fabrics to resist various external effects without discoloration. In recent years, in the international fabric workwear trade, the requirements for dyeing fastness In addition to ensuring the quality of the products, we also pay attention to its safety and environmental protection. The national standard requirements for the fastness of dyeing are water resistance; dry friction resistance and wet friction resistance. The fastness of dyeing required by the EU ecological cloth mark has increased the sun dyeing strength on the basis of the national standard. The fastness of dyeing of knitted mattress fabric , also called color fastness, refers to the ability of colored fabrics to resist various external effects without changing color. In recent years, in the international fabric workwear trade, the requirements for fastness to dyeing are not only guaranteed. In addition to the qu...
Waterproof and moisture permeable fabric waterproof principle Fabric waterproofness refers to the barrier and hate resistance of fabrics when they pass through liquid water. Traditionally, the term "waterproof fabric" is used to describe a fabric that is impervious to impervious fabrics when applied with water pressure, whether liquid or gaseous, not for the entire life. This feature is always maintained inside. Water does not pass through the fabric but can wet the surface of the fabric. Generally, the fabric can be made waterproof as long as it is applied to the surface of the fabric or the fabric is laminated with a dense film that does not pass through the water. Waterepellent fabric refers to the ability of a fabric to resist the penetration of water fabric under static conditions that do not undergo any external force. Water-repellent fabrics allow gaseous water to pass through, while liquid conditions do not allow liquid water to penetrate, which essentially does no...
