A three-roll calender for textiles and a textile calendering method

Abstract

The invention relates to a three-roller calendar for a textile and a textile calendaring method. The calendar comprises a rack, a cloth feeding device, an upper roller, a middle roller, a lower roller, a cooling device, a cloth discharge device and a pressurizing device, wherein the upper roller is a spindle roller and fixed on the rack; the middle roller and the lower roller are respectively a mirror surface heating roller and a hydraulic equalizing roller and movably arranged on the rack; the upper roller, the middle roller and the lower roller can respectively rotate around the respective shaft leads; the middle roller is a driving roller; the upper roller and the lower roller are driven rollers; the pressurizing device is connected with the lower roller; the upper roller comprises a roller shaft and a roller body; the roller body is formed by a pure nylon layer and a nanometer aluminum oxide modified nylon layer. By adopting the three-roller calendar disclosed by the invention, deformation of each roller in the pressurizing process is counteracted, cloth is even in pressure in different breadths, and the glossiness and the softness of the calendared cloth are improved. In addition, the calendar and the calendaring method disclosed by the invention are applicable to the cloth with any thickness and made of any materials.

Description

technical field [0001] The invention relates to a calendering method for textiles and a three-roll calender used therefor. Background technique [0002] In order to prevent the deformation of the rolls during the textile calendering process, resulting in different smoothness and softness at different parts of the product width, the simple way is to make the rolls into a spindle shape to offset the deformation during the work process, but the disadvantage of the spindle shape is that when the roll After the shape is fixed, it can only be applied to one pressure. If the processed fabric is changed, the working pressure must be changed, so the rolls need to be changed. Not only the operation is troublesome but also the cost is high, and different rolls need to be equipped. In order to overcome this problem, the German KUSTERS company and RAMISEH company invented the hydraulic uniform roll respectively. There is a cavity inside the roll, which is filled with hydraulic oil, and t...

Problems solved by technology

However, the nylon roller cannot be used at a higher temperature. Its melting point is 210°C, and its heat distortion temperature is 169°C. Therefore, the general working temperature is below 150°C. At the same time, the friction coefficient of the nylon roller is low, and the cloth fiber is produced during the calendering process. The effect of twisting is poor
