Through-Air Drying of Unbacked Tufted Carpets
Textile Research Journal, 2001Magnetic resonance imaging (MRI) and a pilot-scale laboratory through-air dryer are used to study through-air drying of unbacked tufted nylon carpets. MRI is used to study the effect of the vacuum extraction procedure on local moisture distribution within the carpet and to measure local moisture profiles during through-air drying where airflow rate is

Mechanism of Through Air Drying of Paper: Application in Hybrid Drying
Drying Technology, 2003Abstract During through air drying the internal sheet drying history develops as a succession of local moisture content profiles in the sheet thickness dimension. These profiles were determined by interrupting the through drying of 180 g/m2 6-ply sheets, then quickly delaminating and determining the moisture content of each 30 g/m2 ply.

Combined Impingement and Through Air Drying of Paper
Drying Technology, 1997ABSTRACT For this combined drying process the fundamental characteristics were determined using a unique facility in which air convection drying of paper could be investigated over the full range from pure impingement to pure through drying. As well as light weight paper the program tested heavier sheets, of printing paper grammage, which are not ...

Mass Transfer Coefficients and Drying Rates in Through Air Drying: Part II
Drying Technology, 2009In this study experimental results and analysis are given of convective heat and mass transfer in the drying of tissue and towel products (25 and 50 g/m2 basis weight) under commercially realistic conditions under through flow. Parameter effects on drying rate include process variables such as refining, shaping, commercial forming, initial moisture ...

Improving Carpet Through-Air Drying by Means of Increased Air Permeability 1
Textile Research Journal, 2002Air permeability is an important parameter in through-air drying of unbacked tufted carpet. The primary backing of tufted carpet is the dominant parameter determining carpet air permeability. Carpets of identical construction are tufted using woven and nonwoven primary backings, and the effects of primary backing type on air permeability and drying ...

Design of staged through-circulation drying with air reversals
Chemical Engineering Science, 1995A universal mathematical model has been developed for staged through-circulation dryers with air reversals on the basis of the general expression of the characteristic drying curves. The model can be used for analysis and design calculation of the drying of any material in such a process.

Through air drying of paper—the effect of dryer fabric
Drying Technology, 2018AbstractA custom experimental apparatus is designed to perform through air drying under well-controlled drying conditions such as air temperature and mass-flowrate. Using a novel optical measurement technique, the spatial distribution of moisture content in paper during through air drying is quantified as a function of time. The technique is capable of
