Assessment of Polylactide Properties for Use in Knitted Clothing Products

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.

Investigations of Three‐Layer Systems Intended for Protective Clothing for Prematurely Born Babies

“…These properties constitute an important group of special characteristics of clothing and are of particular importance with regard to products that are in direct contact with the skin of the user. [11] Utility comfort of clothing is determined by the state of physiological, sensory, and physical compatibility between humans and the environment. Utility comfort consists of biophysical, sensory, and psychological comfort, with biophysical comfort being one of the most important parameters considered when evaluating clothing products.…”

Effect of the Surface modification of Cellulose nanofibers on the Mechanical Properties and Disintegrability of Specific PLA/Cellulose Composites

“…Due to its biocompatibility and non-toxic features, PLA could be used, among others, in food packaging, drug delivery systems and scaffolds for tissue engineering [8][9][10]. PLA polymers can also be processed into a wide range of fibrous materials used in the production of woven and knitted fabrics [11]. PLA has a high tensile strength and Young modulus, but it suffers from such drawbacks as inherent brittleness, low toughness, low heat resistance, poor processability, barrier properties and foamability, which result from its slow crystallization rate and low melt strength [3,[12][13][14][15].…”

Study of the Tensile and Bending Stiffness Behavior of Antistatic and Antibacterial Knitted Fabrics

“…The literature reviewed shows that mechanical properties were thoroughly investigated for knitted fabrics manufactured from classical fibers; but this research aims to investigate the mechanical properties of antistatic cotton / antistatic polyester knitted fabrics having carbon black in their structure and treated with antibacterial finishing. However, these textiles were studied mainly for their functional properties, such as electrical and antibacterial [17][18][19][20], with strong focus on their mechanical behavior.…”
