Raincoat, generally refers to clothing made of waterproof fabric with rainproof function&Nbsp; Raincoats are suitable for waterproof fabrics such as adhesive tape, oilcloth, and plastic film. Modern raincoat waterproof fabrics focus on breathability, commonly used such as special nylon and Gore Tex. A breathable raincoat is conducive to the release of hot and humid moisture from the raincoat when worn, increasing its comfort

Scope of application:

Suitable for raincoats made mainly of plastic, waterproof fabrics, etc., not for disposable raincoats.

Test items:

. 2. Accessories (zippers, buttons, heat seals): The zipper should be smooth and smooth, with good engagement and no missing or damaged teeth. The buckle is firmly installed, with suitable tightness and symmetrical buckle positions. The heat seal should be flat, and the width of the heat seal after bonding should not be less than 16; Mm. 3. The sewing thread is smooth and straight, the needle code is uniform and neat, the upper and lower threads are suitable for tightness, and there are no defects such as broken or open threads. The needle pitch density is 5; No less than 13 stitches within cm. 4. Dimensional deviation and mutual deviation: Dimensional deviation and mutual deviation comply with relevant requirements. 5GB/T; 3923.1&Nbsp; The breaking strength of HG/T 2580 fabric should not be less than 200 for textile composite materials; N. The tensile fracture force of plastic materials should not be less than 40 N. 6FZ/T; 80007.1 Adhesion fastness: The adhesion force should not be less than 35; No fracture within N or deformation limit range. 7GB/T; 5713 color fastness plastic material does not fade. 8GB/T; The water pressure resistance of 4744 waterproof textile composite material should not be less than 20; KPa. 9. Aging resistant products should not have adhesion, discoloration, or water ripples under high temperature conditions. The product should not have cracks under low temperature conditions. Formaldehyde content in 10GB 18401 is a colorless gas with a pungent odor. Textiles containing formaldehyde will gradually release free formaldehyde during people's wearing process, causing respiratory and skin inflammation through contact with the human respiratory tract and skin, and also causing eye irritation. The pH value of textiles in 11GB 18401 refers to the residual acid and alkali content in the fabric. If various chemicals in textile printing and dyeing processing are not fully washed or neutralized, the acidity and alkalinity on the fabric are too high, exceeding the range of pH adaptation of the human skin, which can easily cause skin itching, allergies, inflammation and other diseases, and even damage the sweat glands and nervous system of the human body, affecting human health. 12GB 18401 Decomposable Carcinogenic Aromatic Amine Dyes Decomposable aromatic amine dyes refer to dyes synthesized from carcinogenic aromatic amines, commonly known as "prohibited azo dyes". After decomposable aromatic amine dyes are made into clothes, they cannot be distinguished from the appearance of textiles and can only be detected through technical testing, and cannot be eliminated. This type of dye can cause various malignant diseases and absorb carcinogens when in contact with human skin
