Silica sol is a colloidal solution of silica particles dispersed in water. This structure gives silica sol excellent fluidity and dispersibility, and it can mix well with other slurry components. In textile slurry, the addition of silica sol can improve the uniformity of the slurry and ensure a smooth and uniform coating during the coating process, thereby improving the overall appearance and feel of the fabric.
Silica sol has good bonding properties. One of the main functions of textile slurry is to firmly bind fibers and fillers together to enhance the strength and durability of the fabric. The bonding ability of silica sol enables the fabric to maintain good structural stability after coating and drying, reducing problems such as fuzzing and shedding caused by washing and use. This is particularly important in the production of high-end fabrics, because high-end fabrics not only need a good feel, but also excellent durability.
Silica sol also plays an important role in improving the water resistance and anti-fouling properties of fabrics. After coating, silica sol can form a dense protective film on the surface of the fabric to prevent moisture and dirt from penetrating into the fiber. This property can not only extend the service life of the fabric, but also reduce the frequency of cleaning and reduce resource consumption during the washing process. This is of great significance for environmental protection and sustainable development.
Furthermore, the high temperature resistance of silica sol makes it perform well in some special applications. In the textile printing and dyeing process, some processes need to be processed at high temperatures, and silica sol can maintain its performance and will not lose its adhesion or degrade due to high temperatures. This makes silica sol widely used in heat treatment processes, especially in the production of functional fabrics such as fireproofing and antistatic.
Silica sol also has good UV resistance. Under sunlight, ordinary slurry may be degraded by ultraviolet rays, causing the color of the fabric to fade or the physical properties to deteriorate. The anti-ultraviolet properties of silica sol can effectively protect the fabric and maintain its bright color and physical properties. This is essential for the production of textiles used outdoors, especially tents, parasols and other products.
