Abstract

A sportswear fabric should have good stretch and recovery behaviour. This study facilitates an effective design and development of high-stretch sportswear using different knitted structure. Nine types of knitted fabrics were produced by varying the type of fibre and type of structure. An experiment work is done to study the fabric size, stretch and elastic recovery properties. The statistical analysis showed that type of fibre and type of knitted structure significantly influence the fabric stretch. Plain structure fabric showed higher stretch value than rib and interlock-knitted fabric. The high stitch density caused by reduce stretch value in the course- and wale-wise due to yarn floating rather than overlapping influenced the weight and thickness of knitted fabrics. The elastic recovery analysis indicated that the recovery value of plain-knitted structure with polyester-spandex blend is higher among studied fabrics. However, the recovery value decreased over time in comparison with stretch value.

Highlights

  • The heavier weight of knit specimen was, the thicker its thickness was in descending order ‘interlock structure polyester-spandex, micro-polyester and 100% polyester-knitted fabric’, ‘rib structure polyester-spandex, micro-polyester and 100% polyester-knitted fabric’, ‘plain structure polyester-spandex, micro-polyester and 100% polyesterknitted fabric’

  • Thickness and weight of specimen were influenced by density change caused by reducing and increasing fabric size

  • High density caused by floating in course-wise causes more knitted fabric weight gain than by loop overlapping

Summary

Introduction

The stretchable knitted structures play an important role in body comfort and fit. The knitted structures allow wearer the freedom of movement with least resistance due to their stretchability and elasticity [1, 2]. Regular physical activity is important to maintain consistency in human health. To achieve comfort and functional support during various activities such as walking, stretching, jogging, athletes and sports persons use sports clothing [3, 4]. Stretch properties represent a significant mechanical property of clothing material that influences clothing pressure. Stretch properties are measured as the percentage of fabric stretch and fabric growth, and recovery [5–7]
