How does PU coating give nylon Taslon Oxford cloth waterproof properties?

In the diverse field of textile materials, nylon Taslon Oxford cloth has become an ideal choice for many application scenarios due to its excellent comprehensive characteristics. Its excellent waterproof performance is particularly eye-catching, which depends largely on the key PU coating processing link in the production process. So, how does PU coating give nylon Taslon Oxford cloth strong waterproof ability? Behind this lies the sophisticated coating technology and unique film-forming principle. ​

As a widely used textile material, nylon Taslon Oxford cloth has a basic structure composed of warp and weft fibers tightly interwoven. Although this woven structure gives the fabric a certain initial waterproof ability, it still needs to be further improved in the face of strict waterproof requirements. At this time, PU coating technology plays a vital role. ​

PU coating, that is, polyurethane coating, is evenly applied to the surface of nylon Taslon Oxford cloth through specific and precise coating technology. The coating process requires strict control of multiple key factors to ensure the quality and effect of the coating. The selection of coating equipment is crucial, and different types of coating equipment are suitable for different production scales and fabric characteristics. For example, common scraper coating equipment can control the thickness of the coating by precisely adjusting the gap between the scraper and the fabric. When coating nylon Taslon Oxford cloth, the scraper gap is adjusted according to the texture of the fabric and the expected waterproof performance requirements so that the PU coating material can be evenly covered on the surface of the fabric. ​

The temperature and speed in the coating process are also important parameters that affect the quality of the coating. During the coating process, the appropriate temperature can ensure that the PU coating material has good fluidity and is easy to be evenly distributed on the surface of the fabric. If the temperature is too high, the coating material may solidify prematurely and cannot be evenly covered; if the temperature is too low, the material will have poor fluidity and it will be difficult to form a continuous coating. The coating speed needs to match the temperature and the curing time of the coating material. If the coating speed is too fast, the coating may not be fully attached to the surface of the fabric; if the speed is too slow, it will affect production efficiency. For the coating of nylon Taslon Oxford cloth, after a lot of practice and process optimization, the appropriate temperature range and coating speed have been determined to ensure that the PU coating can be evenly and firmly covered on the surface of the fabric.​

Once the PU coating is evenly covered on the surface of the nylon taslon oxford, it enters the critical curing stage. The curing process is the core link for the coating to form a continuous and dense waterproof film. Under specific curing conditions, the molecules in the PU coating material undergo a cross-linking reaction to form a stable three-dimensional network structure. This cross-linking structure gives the coating good physical properties, such as wear resistance, flexibility and waterproofness. The curing process is usually carried out in a heated environment, and the PU coating material is fully cured by precisely controlling the heating temperature and time. For the PU coating on the nylon taslon oxford, it is generally cured within a specific high temperature range. This temperature can ensure that the coating material is fully cross-linked without damaging the fiber structure of the nylon taslon oxford. ​

When the PU coating is cured, the continuous and dense waterproof film formed on the surface of the nylon taslon oxford plays a key waterproof role. From a microscopic perspective, there are many tiny pores between the fibers of the nylon taslon oxford. Although these pores are difficult to detect with the naked eye, they are potential channels for water molecules to penetrate. The waterproof film formed by the PU coating can perfectly fill these pores, just like building an indestructible barrier on the surface of the fabric. When water molecules encounter this waterproof film, due to the dense structure of the film, they cannot easily penetrate, thus effectively preventing the penetration of water. ​

In practical applications, this PU-coated nylon Taslon Oxford cloth shows excellent waterproof performance. In the field of outdoor products, such as making tents, tents need to resist rainwater for a long time under various severe weather conditions. Nylon Taslon Oxford cloth treated with PU coating can reliably prevent rainwater from penetrating, providing campers with a dry and comfortable living space. In the production of assault jackets, the fabric is not only required to have excellent waterproof performance, but also to have a certain degree of breathability. While effectively blocking rainwater, the PU-coated nylon Taslon Oxford cloth can discharge the moisture emitted by the body through special process design, avoiding the wearer from feeling stuffy, and ensuring the comfort and convenience of outdoor sports.​

PU coating is evenly covered on the surface of nylon Taslon Oxford cloth through a specific coating technology, and forms a continuous and dense waterproof film after curing, which fundamentally improves the waterproof performance of nylon Taslon Oxford cloth. This process involves precise control of coating technology, strict control of curing conditions and the microstructural advantages of waterproof film. It is the synergy of these factors that makes nylon Taslon Oxford cloth stand out among many textile materials and become a high-quality choice to meet various waterproof needs. It is widely used in outdoor equipment, daily necessities and other fields, providing reliable waterproof protection for people's lives and activities. ​
