The textile industry has a promising scope in the near future and is flourishing all over the world. With the emerging trends of fashionable dresses among the common people, there is a never-ending demand for high-quality fabrics and textile products in the market. It is important for every textile industry to make sure that the quality of their fabric is the best. If a company fails to provide the best products to the customers, there are very few chances of survival of the company for a long time as the competition is very high in the textile markets. There are many different attributes of fabrics and garments that contribute to their quality which include thread count, GSM, color appearance, texture, smoothness, colorfastness, etc.
Color fastness is one of the most factors that determine the quality of fabric or garment. Most of the buyer have primary requisite of better colorfastness in the garment. It can be addressed as the property of fabric due to which it resists color fading upon exposure to light, washing, rubbing, and perspiration. Color fastness is necessary for the fabrics as running color can be dangerous and allergic too.
There are many factors that can severely affect the colorfastness of fabric. Some of these include the chemical features of the fabric. The synthetic fibers show better fastness than the natural fibers. textile testing instruments
The molecular structure of the dyes also has a significant effect on the colorfastness. If the molecule of the dye if larger in size, it will show better fastness as it can be easily entrapped inside the polymeric chain space the process and temperature used for dyeing also has a significant effect on the color fastness. It is important to perform dying at a prescribed temperature of a particular dye or fabric. If the temperature is increased or decrease, it can lead to bad color fastness. The depth of shade also affects this property of the fabric. The deeper the shade would be, the lower the fastness would be. Additionally, if there are several other different chemicals present in the fabric apart from dyes, it also can alter the color fastness properties of the fabric. Colorfastness also depends on the actual conditions to which the fabric is subjected to.
Colorfastness is tested in laboratories using a crock meter which accurately and precisely gives the exact measure of the color fastness of dyed fabric. The lab testing instrument is used in almost every textile manufacturing and processing industry along with garment export houses and buying houses.
