DF241A系列染色机是我厂在总结多年来生产GR201系列、GR202系列和MF系列染色机经验的基础上，结合近年来纱线染色的新工艺、新技术以及各客户的新要求，博采国外先进染色机长处而开发的立式圆筒形全充满式的高温、高压纱线染色机。
该产品主要适合在140℃以下对棉、毛、麻、涤棉、涤等天然纤维及其混纺织物的绞纱、筒子纱进行染、煮、漂白、清洗等工艺处理。
该机与以前常规染色机相比较，其突出优点为：
一、采用最新设计的目前国内最先进、优良的高效率、高抗汽蚀的混流泵。其染液正反循环通过泵内的换向阀自动完成，泵内叶轮能为染纱过程提供大流量和足够扬程系数，其穿透性强，适染高难织物，被染织物色牢度高，具有很好的匀染效果，适染多种织物。
二、全充满结构：该机具有化料系统（搅拌器和化料桶），加料加压系统（辅泵）、染液内外循环系统（冷却器）。这样能使染色过程在常温高压和高温高压中，对织物完成工艺要求，适用性广，染色色光度好。
三、自动化程度高，工艺重演性好，操作使用方便：因为该机配备电脑控制，使染色操作过程自动化，减少手动操作而引起的人为因素。染色过程完全按照工艺要求运行，各功能、指令帽电器系统程序控制，使工艺具有重演性，减少缸差。
四、合理、完善的操作环境和高度的安全性：该机采用自封式锅口密封，气动式名优口锁紧联动安全装置，且气动式锅盖启闭装置，使用方便，安全可靠。
各管口采用气手两用阀门，锅内的盘管，加热冷却系统均采用自动控制，劳动强度低，操作环境舒适。
DF241 series,dyeing machine is the vertical cylinder type full filling high temperature & high pressure dyeing machine for yarns,which is developed gy our factory on the basis of sumjarizing experiences on producing GR201series,GR202series amd MF series dyeing machinge,combining with new process,new technology and new requiremnets of variors customers on yarm dyeing ,and absorbing advantages of foreing advanced dyeing machines ,This product is mainly suitable for process treatment (such as dyeing,boiling,blanching and cleaning,etc.)under140℃ for cotton,wool,hemp ,polyester cotton and polyester fiber,etc. matural fiber,and reeled yarn & cheese of thier blend fabric.
Comparing with previous nomal dyeing machine, its outstanding advantages are:
1.Adopt the most advanced mixed flow pump(with excellent high efficiency and high cavitation resistance perfomanc)fo newest desigh currently in China. The direct reverse circulaeion tor dyeing is executed by change ralve inside the pump .The impeller inside the pump can provide large flow and enough head coelicient for yarm dyeing procredure.Due to its strong penetrbility,it is suitable for very difficrlt texture and various kinds of textures.The dyed textrue is with high color fastness and good uniform dyeing effects.
2.Full-filling structure:Theis machine is equipped with chemical raw meterial system(beater and chemical material barrel),mat4rial feeding &pressurizing system(auxiliary pump),and intermal & extermal ciculation system of dye liqcr(cooler).Thus the dyeing procedure can be cpmpleted to meet process requiements under both normal tempreature high pressure and high temperature ghgh pressure.The qpplicablity is wide and the dyeing ahade is good.
3.High automation degree with good process repestability and convenient operation:Since thes machine is equipped with computer control system,the dyeing operation.The dyeing procedure can be executed completely according to process requirements.Each function and order can be controlled by program of electric system,thrs the process is with repeatability and the cylinder difference is rseduced.
4.Ressonsble,prefect operating environmert and high safety:This machine adopts selfsealimg type sealing member for kettle,pneumatic kettle locking interlocking asfety device,and pneumatic prening & closing device for kettle cover.It is with convenient operation and is safety *& reliable.Each orifice adoptes & manual dual-purpose valve and the coil heating systems inside kettle are all automatically controlled.Hence,the labor strength is low and the operaftion environment is comfortable.
