EspañolIn modern textile technology, waterproof technology fabric is undoubtedly a striking innovation. This fabric combines modern technology with traditional textile craftsmanship to provide waterproof performance while maintaining a certain degree of breathability and comfort, thus meeting people's needs in various adverse weather conditions.
The development history of waterproof technology fabric can be traced back to the 1970s, when scientists first developed waterproof breathable membranes (WBMs). These membranes are combined with textile materials through lamination to ensure the waterproof and breathable properties of the fabric. These membranes are mainly divided into two types: hydrophilic non-porous membranes and hydrophobic microporous membranes.
Hydrophilic non-porous membranes are continuous non-porous membrane materials processed from hydrophilic polymers such as polyurethane (PU), polyacrylonitrile (PAN), cellulose, etc. The non-porous structure of this material is not easy to absorb foreign matter such as dust, so there will be no clogging of the holes, and the moisture-proof effect can be maintained for a long time. However, in order to obtain good breathability, the fabric needs to be close to the skin and in direct contact with sweat, which greatly reduces the comfort of the fabric and limits the application of hydrophilic non-porous membranes.
In contrast, hydrophobic microporous membranes are made of hydrophobic polymers as basic raw materials through phase separation, biaxial stretching or electrospinning. The interior of the membrane is an irregular mesh or sponge structure with a large number of tiny micron-sized interconnected pores. This structure makes the hydrophobic microporous membrane not need to be in direct contact with the sweat produced by the human body, thereby ensuring the comfort of the human body. The research on waterproof and breathable membranes is mainly focused on hydrophobic microporous membranes.
Waterproof technology fabrics have a wide range of applications, especially in outdoor clothing, protective clothing, wound dressings and smart clothing. They show good application prospects. In outdoor clothing, waterproof technology fabrics can not only effectively resist wind, rain and cold, but also maintain good breathability and comfort, so that the wearer can still stay dry and warm in adverse weather conditions. In the field of protective clothing, waterproof technology fabrics provide reliable protection for workers to prevent the invasion of harmful substances. In the medical field, the application of waterproof and breathable membranes has brought revolutionary changes to wound dressings, which helps wounds heal and recover.
As an important textile technology innovation, waterproof technology fabrics are constantly changing people's lifestyles and working methods. By combining modern technology with traditional textile processes, waterproof technology fabrics not only provide waterproof performance, but also maintain good breathability and comfort, providing strong protection for people's life and work in various adverse weather conditions. With the continuous advancement of technology and the continuous expansion of application fields, the development prospects of waterproof technology fabrics will be broader.
