Washing and Drying Blankets

The dyestuff completly combines with the blanket fiber after adjustment, shape-stabilization, dyeing and high temperature fixation to the blanket greige, but plenty of chemical additives, thickening agent and a little unreacted dyestuff still appear on the surface of the fiber, all this must be removed by water washing. The water washing device is currently consisted of twelve to fourteen water tanks, and on top of it, there exists a rubber cylinder, more importantly, we can adjust the size of crevice between rubber cylinders. Since the rubber cylinder have relative pressure towards the blanket, when the color fixed blanket delivered by mechanical transportation, it will pass by the water tank first, and then the thickening agent will dissolve in it, the sewage containing in the blanket will be squeezed out again after the extrusion of the rubber cylinder. After cleaning and extrusion like this for twelve to fourteen times, the blanket will be completely clean and tidy. 

What is more important in this process is that we need to soften, dishevel and flatten the washed blanket in the last water tank, which is a critical step in all procedures. The basic raw material of blanket is polyester fiber, and polyester fiber on its own is extremely rough, even to the extent that it pricks the hand. Research specialist staffs in Nanjing Lovely Bear Blankets co.,Ltd, devoted themselves to the innovation of various types of flattening and fluffing agent on the basis of special structure of polyester fiber, such as the combination of flattening and fluffing agents and anti static agent MS-30 from Nanjing Yuyang Technology co., Ltd, dispersed uniformly in the last water tank after chemical reaction with the sewage disposal agent, when the washed blanket pass through its aqueous solution(major structure of it is high polymer amino silicone polyester), it can efficiently appear uniformly on the surface of polyester fiber. And the temperature is over eighty degrees Celsius during the process of drying, so this kind of chemical agent will combine with the polyester fiber, forming the perfect protective tissue on the surface of the fiber, which makes the blanket smooth and soft, especially having obvious effects to "cloudy mink blanket", "gold mink blanket" and super fine fiber, and the processed blanket is better than the fur of mink. 

The key points of this section: Firstly, the water washing device of the blanket must be designed reasonably, because there is plenty of sewage in the vapor, which makes it important to purify and reuse the sewage. Secondly, qualities and effects of chemical additives and flattening and softening agents play an important role in the hand feeling and quality of the blanket. Thirdly, this craftwork is applicable to the overwhelming majority of fur, plush, blanket and carpet in the market.
