Analysis and modeling of drying behavior of knitted textile materials

Abstract

Drying properties of textiles in summer and/or after any kind of physical activity resulted in sweating is of great importance for garments with high clothing comfort. This study analyses the drying behaviour of knitted fabrics produced from various fibres at different ambient air conditions. Drying kinetics and modelling of fabrics dried in standard environmental conditions were investigated in the first part. Polyester and lyocell fabrics were found to be the fasted dried samples. A two-stage modelling that is a combination of linear approach and thin-layer equations were used, and the best fitted equation was found to be the logarithmic one. The two-stage model was also proved to predict the drying rate. The second part included the effects of ambient humidity on drying times and rates. Drying time of polyester and polyester blended fabrics was affected by the increase in the humidity to a great extent. Furthermore a quadratic function was found to be highly correlated with the computed data so it was proposed to define the drying behaviour by ambient air humidity and drying time.

Design of Epidemic Prevention Medical Special Clothing Based on Mathematical Model Analysis

“…Article. In this article, the design of special clothing for epidemic prevention and medical treatment is taken as the research object, and the mathematical model analysis method is creatively used to combine the research of epidemic prevention and clothing design in the medical field through computer science and technology, which opens up a new perspective for the design of special clothing for epidemic prevention and medical treatment [12]. eoretically speaking, the design of special clothing for epidemic prevention and medical treatment based on mathematical model abandons the previous model of mechanical design on demand and evaluates and considers the quality of special clothing for epidemic prevention and medical treatment from all aspects through the analytic hierarchy process, so as to extract the key factors that should be considered in the design of special clothing for epidemic prevention and medical treatment [13].…”

Drying kinetics and mechanical properties of low temperature microwave dried cashmere fibers

“…[17][18][19] Some researchers have investigated various thin-layer models to describe the application of MVD in different food products, 16,17 and some researchers have applied thin-layer drying models to textile product drying. For instance, Cay et al 20 use linear approach and thin-layer equations to predict the drying rate of knitted textile materials, and Akyol et al 21 use thinlayer models for simulation of the textile drying process. Therefore, it is feasible to use thin-layer drying models to predict the drying kinetics of cashmere fibers under MVD.…”

Implementation of Pre-Heating System in Stenters for Improving Machine Performance and Increasing Efficiency

“…Wet cellulosic fabrics have been found with increased drying time as they are generally hygroscopic in nature and hold a significant amount of bound moisture. Unbound (free) moisture can be assumed for the synthetics like polyester fabrics which lead to shorter drying times [5].…”

“…Mechanical pre-drying is regarded as one of the energy-efficient measures of textile wet processing [9]. During pre-heating/drying, the evaporated water from the fabric surface is carried out to the surrounding air via a diffusion mechanism [5]. Though mechanical de-watering is much economical than pre-drying using heat, the remaining moisture regain is comparatively higher in case of mechanical means since much of the residual water creates chemical bonding with fiber.…”
