Document Type and Number:
WIPO Patent Application WO/2020/006786
Kind Code:
A1
Abstract:
A production process of a filter cloth using mixed thermally-melted yarn sprayed cotton as a base layer, comprising feeding a material on layers of the filter cloth, feeding the material on an upper layer of nonwoven fabric, a middle sprayed cotton layer and a lower layer of nonwoven fabric, wherein the middle sprayed cotton layer uses a sprayed cotton layer having a thermally-melted yarn; scattering powder for the middle sprayed cotton layer, conveying carbon powder into a powder scattering mechanism, and scattering the powder to the middle sprayed cotton layer so that a layer of mixed powder is uniformly scattered to the middle sprayed cotton layer during transmission; drafting the upper layer of nonwoven fabric, the middle sprayed cotton layer and the lower layer of nonwoven fabric by means of a drafting mechanism, and then conveying same into an oven mechanism in a stacked manner for heating; pressing the heated stacked material; and sending the pressed material into a cooling mechanism for cooling. By doping the thermally-melted yarn to the middle sprayed cotton layer, the thermally-melted powder or glue can be prevented from covering the carbon powder, and influencing the filter effect of the carbon powder; and the filtering effect of the carbon powder can be exerted to the largest extent.
