Functional Model of a Warp-Knitted Machine for Producing 3D Technical Knitted Fabrics

Abstract

The article describes the construction and testing of a functional model of an innovative warp – knitting machine for technical spatial knitted fabrics with an original structure. Design assumptions regarding the geometrical, kinematic and driving characteristics of the machine are described. The functional model as well as its physical implementation as a research stand are presented. The production phases of the 3D knitted fabric are also demonstrated. The research results are described and their importance for the construction of a machine prototype of the production version are emphasised.

The effect of fabric structure on the pilling and abrasion resistance of interlock weft-knitted fabrics

“…As seen in all fabric structures, by increasing the cycles of abrasion, the weight loss percentage of the fabrics increases, which represents the decrement in the fabrics’ abrasion resistance. This observation confirms the findings of previous research (Emirhanova and Kavusturan, 2008).…”

“…Hence, the higher number of miss or tuck stitches in the fabric structure will lead to the lower abrasion resistance of the fabric. This finding is in confirmation with the results of previous researchers (Emirhanova and Kavusturan, 2008), while in contrast with the results observed by Kane et al . (2007).…”

“…According to the results, in all fabric structures, by increasing the cycles of abrasion, the pilling tendency of the fabrics increases. This finding has been reported by previous researchers as well (Emirhanova and Kavusturan, 2008; Uyanik and Topalbekiroglu, 2017). Furthermore, increasing the number of miss/tuck stitches in the fabric structure enhances the pill formation, and this phenomenon is dominant in fabrics containing tuck stitches in their structure.…”

This finding is in confirmation with the results of previous researchers (Emirhanova and Kavusturan, 2008), who showed that fabric structures containing tuck or miss stitches exhibit lower resistance to pilling, while in contrast with the results of Uyanik and Topalbekiroglu (2017), who observed that the combination of tuck-knit stitches in the structure of single jersey fabrics improves the pilling performance of the fabric compared to fabric with knit stitches.…”

“…Emirhanova and Kavusturan (2008) studied the effects of knit structure on the pilling and abrasion resistance of winter outerwear knitted fabrics. Among fourteen different knit structures considered, tuck stitch fabrics exhibited the lowest abrasion resistance.…”
