Experimental study of structural characteristics, dimensional change in washing, non-creasing properties and air permeability of Swiss double piqué flax knit fabrics

Abstract

The structural characteristics, dimensional change after four washing cycles, non-creasing properties and air permeability of Swiss double piqué knitted fabrics from cotton/flax (70% cotton, 30% flax), PAN/flax (70% PAN, 30% flax) and 100% flax yarns have been investigated. These knitted fabric samples of varying densities were produced on a 10 -gauge circular knitting machine. The results of investigation showed that the structural characteristics, dimensional change in washing, non-creasing properties and air permeability are highly dependent on the type of yarn used. Besides the type of yarn, the structural characteristics, such as the number of wales W and courses C per centimeter, fabric stitch density S, weight Ws, and fabric tightness K, are also influenced by the average loop length la. The weight Ws and thickness t of knitted fabrics are determined by the diameter of the yarn used. Usually, primary dimensional alterations of knitted fabrics of all yarn types occur after the first and second washing cycles. The non-creasing properties of the examined knitted fabrics are mainly affected by the type of yarn, rather than the average loop length la. Lastly, the air permeability AP of knitted fabrics is affected by the type of yarn, the average loop length la, and fabric density S.

“…These issues have been addressed by scientists M.S. Bukhonka (2023) studied the effect of mixing natural and synthetic fibres on improving the consumer properties of the resulting materials, which is carried out to achieve a high level of comfort and functionality of finished textile and knitted products.…”

The effect of miss stitches on the dimensional and stretch properties of double weft cotton/flax knitted fabrics

“…Stitches such as knit, miss, and tuck can lead to variations in fabric properties. [3][4][5] Each knit structure has its own distinct characteristics, and the choice of a particular structure depends on the desired properties and intended application of the fabric. [6][7][8][9] Choosing the appropriate knit structure for cotton knitted fabrics becomes crucial to effectively enhance properties like smoothness of the fabric surface, air permeability, heat transmittance, and hydrophilicity.…”

“…22 The width repeat of the miss stitches influences the dimensional changes of the single weft jacquard knitted fabrics. 23 Investigation of the influence of the type of relaxations such as knitting&dry relaxation, dye&dry relaxations, dye&wash relaxations for the single jersey, 1 × 1 rib and interlock knit structures on the dimensional properties of cotton knitted fabrics showed that the shape of the loop in the fabric and loop length of yarn are the main factors which are responsible for the dimensional properties. 24 Knitted garments experience various stresses and loads throughout their use, which can vary in magnitude, direction, and duration.…”

Analysing the Effect of Flax Fiber Content on Knitted Garments

“…It has been stated that linen blended fabrics increase cotton UV protection factor and color efficiency, reduce burst strength and allow more moisture absorption (Sanad, 2011). In another study, Bukhonka (2023), conducted a study on the dimensional changes and air permeability of Swiss double pique knitted fabrics produced using PAN/linen, cotton/linen and pure linen. It was determined that there was more dimensional change in knitted fabrics made from cotton/linen and pure linen yarns and that the knitted fabric made from pure linen yarn had the highest air permeability (Bukhonka, 2023).…”
