合成纤维或以合成纤维为主要成分的混纺织物,通过加热处理——即在高温下对合纤织物拉幅,以松弛从纤维到织物加工过程中产生的分子间的内应力,从而使织物外观平挺,尺寸稳定,这种工艺称为热定型。它还能使织物在整理过程中染料、助剂的焙烘和固着。因此热定型机是合纤织物印染加工的主要设备之一。织物在定型整理时的加工温度一般在180—200℃左右,热室(即烘房)内的传热方式主要是靠热空气对流,即利用加热装置和空气的循环,使空
Synthetic fibers or synthetic fibers as the main component of the blended fabric, by heat treatment - that is, the synthetic fiber tenter at high temperature to relax from fiber to fabric during the process of intermolecular internal stress, so that the fabric appearance Leveling, dimensional stability, this process is called heat setting. It also enables the fabric in the finishing process of dyes, additives curing and fixation. Therefore, heat setting machine is a synthetic fiber printing and dyeing processing of the main equipment. Fabrics in the finishing process temperature is generally 180-200 ℃ or so, hot room (ie drying room) in the heat transfer mode is mainly by the hot air convection, that is, the use of heating devices and air circulation, the air
