Abstract:

The article presents the results of a study work on the assessment of selected structural and performance characteristics of weft knitted fabrics, produced from the commercial multifilament polylactide yarn PLA 6201D. The work was carried out on PLA materials with the aim of application in lightweight outerwear. The materials presented are examples of solutions used in the industrial process of the manufacturing and finishing of so-called seamlesswear products. The structure of the materials in the solutions of left-right stitch applied was determined by the indicator of the degree of filling of the knitted fabric “k”, used in the filling characteristics of the linear structure of knitting materials made from the same type of yarn. The functional properties of the materials were determined in the scope of selected indicators, important in the aspect of physiological comfort and clothing’s quality of wear. The PLA yarn was subjected to the assessment selected qualitative and hygroscopic indicators, which was carried out in relation to selected multifilament polyester yarns of similar linear mass.
