All-cotton no-iron technology can be called a high-tech technology in the 21st century, so what is its ironing mechanism? Woolen cloth? As we all know, cotton fiber molecules are generally in a state of disorder and no stationary phase. When cotton fabrics are affected by water molecules and external forces, relative slip occurs between macromolecular chains, resulting in so-called denaturation under the action of external forces. When the external force or water molecules are removed, the degeneration caused by this slippage cannot be restored. This is the wrinkling phenomenon of cotton fabric.

If a hinge network can be created between cotton fiber macromolecules, then there will be no relative slippage under the action of external force or water molecules, that is, no movement will occur. wrinkle. The method to promote the formation of a hinge network between macromolecules is based on resin finishing. Through finishing, a cross-linking reaction occurs between the resin molecules and the cotton fiber molecules, thereby achieving the denaturation and recovery properties of the cotton fiber. The cotton fabric can be washed after being made into clothing. No need for ironing and no wrinkling. This kind of finishing resin usually uses formaldehyde resin or low-formaldehyde modified 2D resin. When configuring the resin finishing liquid, in addition to formaldehyde or 2D resin, it should also be equipped with various additives such as catalysts, softeners, etc. Use it to improve fabric feel and comfort.

Iron-free finishing technology usually consists of 4 process principles depending on the finishing machine and processing process: 1) Pre-baking process: Fabric-top Resin finishing-drying-baking-garment making-ironing. 2) Post-baking process: fabric-resin finishing-drying-garment making-ironing-baking. 3) Impregnation method process: fabric-garment making-resin finishing-drying-ironing-baking 4) Vapor phase method process fabric-adding additives-garment making-ironing-vapor phase treatment.

Due to the strengthening of people’s awareness of environmental protection and health care in dressing in recent years, the European Community, the United States, Japan and other developed countries have all proposedenvironmental protection For textiles and clothing requirements, the internationally recognized standard for ecological textiles is the European “Oeko Tex standard 100” standard. Clothing that meets this standard can be labeled as environmentally friendly clothing.
