Abstract:In order to solve the problems such as short service life,more hairiness and broken ends of travelers in high-speed spinning,the Taguchi test method is introduced and the wear resistance of Ni-W-P alloy coating on travelers are studied by the method.The signal noise ratio of the research results is analyzed,the primary and secondary relationships of the effects of sodium tungstate,organic amine,sodium citrate and pH value on the wear resistance are obtained,and the optimal combination of coating preparation process is put forward.The results show that the three main factors affecting the wear resistance of Ni-W-P alloy coating of travelers are the concentration of sodium tungstate,sodium citrate and organic amine,the validation numerical test is carried out according to the optimized factor ratio,and the experimental and predicted values of signal noise ratio are -0.239 754 and -0.399 590.It is pointed out that the wear resistant layer of electroless plating Ni-W-P alloy can effectively improve the wear resistance of traveler and prolong its service life.The application of traveler with Ni-W-P alloy plating in spinning can reduce yarn hairiness and broken ends,improve yarn quality,and the service life of the traveler is not less than 15 d,and can meet the requirements of high-speed spinning and long service life.
