Waterproof breathable fabric includes two aspects of protective clothing performance
1. Waterproof and breathable performance
The performance of the waterproof breathable fabric includes two aspects of the protective clothing performance: on the one hand to prevent moisture from passing through the fabric, and on the other hand to allow the device to emit into the fabric the ability to exude, that is, breathe the heat of the woven object. Reflective clothing manufacturers for a wide range of people, road traffic police, night action police, sanitation workers, construction workers, the elderly and children, outdoor activities, cyclists, travelers are suitable for wearing reflective safety clothing. Reflective clothing can reduce night traffic accidents reflective safety clothing, it is the reflective film placed on the surface of the clothing, for night road or road work safety clothing. In the case of no interference at night, the effective distance of reflection and luminous is 500 meters, the safety suit is simple to manufacture, convenient to change the film, low cost, easy to promote, is an ideal night safety protective clothing. An indication of the fabric's ability to allow water vapor to vent into the skin against the environment. Reflective clothing can reduce night traffic accidents reflective safety clothing, it is the reflective film placed on the surface of the clothing, for night road or road work safety clothing. In the case of no interference at night, the effective distance of reflection and luminous is 500 meters, the safety suit is simple to manufacture, convenient to change the film, low cost, easy to promote, is an ideal night safety protective clothing.
2. PET fabric main development process is coated and laminated fabric, the auxiliary silk of the development of high density fabric. Clad fabrics and laminated fabrics, because it can achieve high water and moisture permeability, and may be required to provide different grades and products of different requirements to occupy the market. PET fabrics such as claim impervious to water and human sweat and moisture through the fabric. According to the claims, the waterproof and permeable polymer film should meet the following conditions: (1) the pore size should be larger than the water vapor molecules; ② Under normal condition, the water in the skin is lost 250 g/m224h, palm, foot is 500 g/m224h. Therefore, the material considered is ideally to achieve a water vapor permeability of at least 4000 g/m224h.
3. Waterproof breathable fabric treatment methods can be divided into: coated fabric: directly coated fabric, transfer coating, foam coating, or wet inverted phase technology coating, surface pore closure or coating agent reduced to a certain degree, so as to obtain water resistance. Coating agent, which includes: neoprene rubber, polyvinyl chloride, polyacrylate, polyurethane, silicone rubber, polytetrafluoroethylene, polyvinylidene fluoride, etc. Wet-permeable cloth is obtained by the action of microporous structure or by a special method of forming a coating layer of hydrophilic paint in groups. Due to the raw material and the treatment itself, the contradiction between air permeability and water pressure resistance and water washing resistance is not well solved in this method. Laminated fabric: The waterproof breathable microporous film or non-porous hydrophilic film, using a special adhesive, through the lamination process of ordinary fabric composite together, to form a waterproof breathable laminated fabric. Fabric can be laminated when two or more layers of fabric are made. Protective fabric laminating not only performs well, but also has a wide selection of technologies, design flexibility, and is non-polluting. Currently in the high share of laminated fabric waterproof breathable fabric market. After this by the United States WLGORE formed products produced by PTFE microporous membrane, and called for Gore-Tex fabric of moisture permeability waterproof laminated fabric, moisture capacity, high water resistance, good comprehensive performance, is considered to be the world's advanced waterproof and breathable cloth. PTFE microporous membrane microporous structure can solve waterproof, wind proof, moisture permeability, moisture transfer performance and flexibility, durable, lightweight, waterproof, washing resistance, and low cost, has good chemical stability, thermal stability, water resistance, flame retardant, moisture resistance and water hole processing characteristics, making the preparation of the preferred material selective penetration membrane. Protective clothing in addition to waterproof breathable fabric and fabric anti-mosquito, anti-static fabric, flame-retardant fabric, fabric anti-acid and the like.
The 2023 Industrial Protection and Occupational Health Exhibition opened on October 24th at the Dusseldorf Exhibition Hall (A+A 2023) in Germany
Including the Chinese flame retardant cloth base, its characteristics mainly lie in improving the management of flame retardant cloth base layer from bottom to top cover adhesive layer,
First of all, flame retardant non-woven materials can be divided into three categories: nonwoven polyester flame retardant, flame retardant polypropylene nonwoven and nonwoven viscose flame.
Electric arcs, though lasting only a fraction of a second, are hazardous to life. Reflective clothing It is the reflective film placed on the surface of clothing, used for night road or road work safety clothing.
