A good pre-treatment in cotton, a proper washing in wool and a good finish are not possible to mention a successful pre-treatment without proper thermofixing in all synthetics, but especially in polyester products. According to a research done by a textile company, only 23% of the faults are real painting and printing, 11% is the finishing fault and the remaining is the indirect and direct pre-finishing fault. As a result of pre-finishing processes, which are the first finishing treatments of all white, painted and printed fabrics, some irregularities already existing in the fabric may be removed, or new defects or irregularities may occur in the fabric. The reason that makes the job hard and which in many cases makes it possible to realize the importance of a good and correct frontrunner is that most of the mistakes that result from the pre-finishing are not immediately visible but become visible only after the oppression and especially after the straight color. A good pre-finishing process is only the result of sizing, trash, oil, wax, pectin, hemicellulose, colored substances etc. inside or outside the fibers in the fabric. And it is not sufficient to ensure a good degree of hydrophility and whiteness. To be able to talk about a good frontrunner; 1. It is homogeneous in all the effects that are provided (such as trash pouring, desizing, hydrophilicity, whiteness, swelling of the fibers, pH value and moisture level of the lifting). 2. No damage to the fibers, 3. Not coming to the broken fruit in the fabric, 4. Good dimensional stability Must also be provided. Pre-finishing operations are done in principle as follows: 5. The reactive groups, which are basically blocked, are released. 6. The effects of the finishing process, such as subsequent dyeing and printing, will be completely eliminated. Thanks to a good pre-finishing process; The cost of operations such as repainting and correction is reduced. The damages caused by the "second quality goods" are prevented. Foreign materials found in the fiber structure are removed. For example, raw cotton and the raw cotton fabric obtained therefrom have remarkable amounts of matter and impurities.
