Determination of yarn and fiber diameters after swelling using a capillary rise method

Capillary kinetics of textile knitted fabrics are investigated considering the effect of transverse swelling in fiber and yarn scales. A mathematical model was developed based on the industrial construction parameters, the capillary mechanism and the swelling ratio on both porosity scales: macro and...

Description
Summary:Capillary kinetics of textile knitted fabrics are investigated considering the effect of transverse swelling in fiber and yarn scales. A mathematical model was developed based on the industrial construction parameters, the capillary mechanism and the swelling ratio on both porosity scales: macro and micro. The capillary kinetics are used to determine the yarn and fiber diameters after swelling and compared to those determined using a microscopic method. In order to validate our model, a series of experiments was conducted on jersey knitted fabric using raw materials with different swelling ratios: cotton and PET. The results showed good agreement between the two methods of diameter determinations.
