The difference between the use of Gore-Tex Jackets and ordinary Jackets
Many Jackets use PU and TPU materials, also waterproof and moisture permeable, but they are very different from GoreTex's E-PTFE materials in actual outdoor environments.
First, the three major types of waterproof and breathable fabrics on the market today:
1. High-density fabrics: Use high-count cotton yarns and in fact ultra-fine synthetic fiber fibers to make tight fabrics with high water vapor permeability and waterproof properties after water repellent finishing. The high density is characterized by good moisture permeability, good softness and drape, but low water pressure resistance (usually less than 1 meter), high defective rate, difficulty in dyeing and finishing, and poor edge rub resistance.
2. Coated fabric: can be divided into hydrophilic coating and microporous coating fabric (TU and TPU). Hydrophilic coatings coat the surface of the fabric with a hydrophilic coating, which is waterproof because it covers all the voids in the fabric. If there are hydrophilic genes on the polymer chain and their content and arrangement are appropriate, they can interact with water molecules, adsorbing water molecules on the high-humidity side by means of hydrogen bonds and other intermolecular forces, and passing the hydrophilic gene clusters on the polymer chains. Desorb on the side of low humidity. Coated fabrics are generally simple to process and are characterized by low moisture permeability and low water pressure resistance. Due to the limitations of raw materials, processes, and the method itself, the contradiction between moisture permeability, air permeability, water pressure resistance, and washability has no
