Description
Technical Field
The invention belongs to the field of functional coated textiles, and particularly relates to a preparation method and a coating device of an ultrathin waterproof coating fabric.
Background
With the development of science and technology, the progress of social economy and cultural level and the improvement of the requirements of people on living matter level, the pursuit of comfort, beauty and functionality of clothing has become fashionable. In recent years, lightweight textile fabrics have become popular with consumers. The light and thin textile fabric is made of proper fiber raw materials and adopts effective spinning, weaving and dyeing and finishing processing processes on the premise of not changing the original style of the fabric, so that the weight of the fabric is light and the texture is light and thin. On the premise of ensuring the original performance of the fabric, the fabric is further thinned and thinned, and good comfort can be provided for users in the taking process. For the light and thin functional fabric, the aim of the fabric design is to make the weight of the fabric smaller in unit area, and at present, the preparation of the light and thin functional fabric is usually realized by optimizing raw materials, adjusting processing technology and fabric structural design and optimizing a functional finishing scheme. For outdoor fabrics, a large amount of sweat is usually generated when people wear the outdoor fabrics, and if the outdoor fabrics cannot quickly discharge sweat to the outer surface, discomfort of human bodies is easily caused.
It would be desirable to develop an outdoor fabric that is lightweight and thin, has a waterproof effect, and is capable of rapidly discharging sweat to the exterior surface. The above-mentioned effects are generally achieved by a different-surface waterproof/hydrophilic finishing, and the differential capillary effect is utilized to enhance the moisture-conducting effect, thereby improving the wearing comfort. At present, when the outdoor fabric is prepared, firstly, waterproof finishing is carried out on the fabric, and then single-sided coating finishing is carried out, but a layer of continuous film is usually arranged on the surface of the outdoor fabric, so that the air permeability of the outdoor fabric is greatly affected, and meanwhile, the method is still higher in sizing. Earlier research shows that when a layer of coating with a hydrophilic effect is coated on the waterproof fabric, when the viscosity of a coating slurry system is higher, a more uniform continuous coating can be obtained, but the air permeability of the fabric is greatly influenced; however, when the viscosity of the system is reduced, the surface energy of the waterproof fabric is low, so that the coating slurry cannot form a uniform coating on the fabric.
