The finishing process of jeans is the key link to improve their texture and feel, which involves multiple steps and methods.
First of all, the washing process is the top priority. Stone washing is a classic washing method. By tumbling jeans with pumice in the washing machine, the surface of the fabric is worn out, making the denim softer. In this process, the size, number and length of the pumice will affect the final texture.
For example, appropriately increasing the number of pumice and extending the washing time can make jeans have a stronger wear effect, and have a time-worn texture. At the same time, enzyme washing is also a common method, using biological enzymes to decompose the slurry and part of the fiber on the surface of denim, making the fabric softer and smoother. Different types of enzymes and concentrations can produce different degrees of softening effects. For example, the use of cellulase can accurately control the degree of wear of the fabric and improve the delicateness of the feel.
Secondly, the use of softener has a direct effect on improving the feel. After washing, adding high-quality softener can make jeans feel more comfortable. Softener can fill the gaps between denim fibers and reduce the friction between fibers. Silicone softener is a commonly used one. It can form a protective film on the fiber surface, making the fabric have a good smooth feeling. Moreover, the amount of softener and the treatment method are also critical.
If the amount is too much, the fabric may be too greasy and lose the original stiff texture of denim; if the amount is too little, the ideal soft effect cannot be achieved. Therefore, it is necessary to accurately control the amount of softener according to the material of the jeans and the desired feel.
In addition, the resin finishing process can improve the texture of jeans. By applying resin on the surface of denim, the fabric can be made more stiff and stylish, and its wear resistance can also be increased. In the resin finishing process, factors such as temperature, pressure and time need to be strictly controlled.
For example, appropriately increasing the temperature of resin finishing can speed up the reaction between resin and fiber, but too high a temperature may damage the fiber. This process allows jeans to have better shape retention while maintaining softness, so that the wearer can feel a good texture.
Finally, surface treatments such as sanding and calendering can also enhance the texture of jeans. The sanding process is to use a sanding machine to grind a layer of fluff on the fibers on the surface of denim, making it feel warmer and softer. Calendering is to use high-temperature and high-pressure rollers to calender the surface of jeans, making the surface of the fabric smoother and more glossy. The comprehensive use of these finishing processes can enhance the texture and feel of jeans in many aspects, making jeans not only comfortable to wear, but also having a unique sense of quality.
