Experimental Study Of Textile Fibers Rapid Drying Method

The content analysis of textile fiber is one of the important indicators of physical andchemical performance of textile products, as well as an important means of textiles anti-fraudinspection regulation. For blending textiles that cannot be broken up, chemical dissolved methodis the main current way as a quantitative analysis of textile fiber content. Meanwhile, drying is acrucial procedure in chemical dissolved method, and the drying efficiency is a vital factor thatinfluence the efficiency of detection directly. The standard provisions of the state stipulates thatthe basic method of textile fiber drying is oven drying method. Specifically, textile fiber ought tobe put inside the airtight ventilation oven for about4~16hours. Although the results are accurate,stable, but it is time-consuming, which greatly restricted the efficiency of quantitative analysis oftextile fiber content.In this article, in order to find a fast drying method of textile fiber, infrared drying methodand microwave vacuum drying method are carried out respectively, and explored combined dryingplan of the two methods.(1)In the research of infrared drying experiment, the research object is wool textile fiber, andinfrared drying experiment was carried out. With the single factor experiment, the temperature, theinfrared radiation distance and the influence of base mass of a single dry sample to the dryingcharacteristics are studied. The results showed that higher temperature, farther distance, andsmaller dry base mass can induce a faster speed of drying. By using linear regression analysisprogram, different drying models are analyzed and compared. The conclusion is that the pagemodel can describe the process of wool fiber infrared drying better, which can be used to predictdrying rate and moisture content of each drying period. The mathematical model of infrareddrying about wool fiber is established.(2)In the research of microwave vacuum drying experiment, the research object is wooltextile fiber, and microwave vacuum experiment was carried out. With the single factorexperiment, the loading capacity, microwave power and the influence of base mass of a single drysample to the drying characteristics are studied. The results showed that smaller load, greaterpower of microwave can induce a faster drying rate, while the mass of drying base has no influence on the drying rat. By using linear regression analysis program, different drying modelsare analyzed and compared. The conclusion is that the page model can describe the microwavevacuum drying of wool fiber better, which can be used to predict drying rate and moisture contentof each drying period. The mathematical model of microwave vacuum drying about wool fiber isestablished.(3)The alliance plan of microwave vacuum and infrared drying experiment was discussed. Bythe three factors, which are microwave power and mass ratio, microwave time and infraredradiation distance, the microwave vacuum and infrared drying orthogonal experiment is carriedout with taking the average drying rate as the experimental index. The conclusion is that the sortorder of the three factors to the influence of the average drying rate of alliance drying is thatmicrowave power and mass ratio, microwave time and infrared radiation distance.
