--According to the feedback from the market, some customers can't get the required performance after using wet rubbing fastness improving agent on denim fabrics.Through the customer's finishing process, we know that the problem is the drying temperature, generally it needs to be dried at 100-120 ℃ after dipping treatment to achieve the desired effect, while the customer actually drying temperature is only 60-80 ℃, which can not make the wet rubbing fastness improving agent better combine with the fabric, thus affecting application effect. In order to solve this problem, our company has developed a special wet rubbing fastness improving agent for jeans HT-819, drying temperature at 60-80 ℃ and will not affect the application effect.
