This study aims to deal with the dyeing of nylon-/cotton-blended fabric in one bath using direct and acid dyes.

Abstract

Purpose

This study aims to deal with the dyeing of nylon-/cotton-blended fabric in one bath using direct and acid dyes.

Design/methodology/approach

The cellulose in cotton/nylon-blended fabric was chemically modified using 3-chloro-2-hydroxypropyl tri-methyl ammonium chloride (CHPTAC) as cationizing agent to impart positive charge on the cellulose. The modified and unmodified blended fabrics were dyed in a single bath with direct and acid dyes under various concentrations of 0.5, 1, 2, 4 and 6 per cent on the weight of fabric by exhaust method. The dyeing of modified and unmodified fabrics was characterized through the properties such as K/S and colorfastness to washing, rubbing and light.

Findings

The modified fabric exhibited higher color yield, comparable rubbing fastness and good washing fastness.

Originality/value

The dye uptake was maximum in a single-bath dyeing process of nylon-/cotton-blended fabrics without electrolyte addition, which minimizes the impact of dyes on environment.

This paper aims to investigate the influence of picking sequence, weave design and weft yarn material on the thermal conductivity of the woven fabrics.

Abstract

Purpose

This paper aims to investigate the influence of picking sequence, weave design and weft yarn material on the thermal conductivity of the woven fabrics.

Design/methodology/approach

This work includes the development of 36 woven samples with two weave designs (1/1 plain and 3/1 twill), three picking sequences (single, double and three pick insertion) and six different weft yarn materials (cotton, polyester having 48 filaments, polyester with 144 filaments, spun coolmax having Lycra in core and coolmax in sheath, filament coolmax and polypropylene). The thermal conductivity was measured using ALAMBETA tester.

Findings

The results showed that weft yarn material, weave design and picking sequence have a meaningful impact on the thermal conductivity of woven fabric. The value of thermal conductivity was lowest for the fabrics with three pick insertion and 3/1 twill weave in all weft yarn materials.

Research limitations/implications

Plain woven fabric with single pick insertion is feasible for summer wear to enhance the comfort of wearer. By changing the warp yarn grouping and material, improved thermal conductivity/resistance can also be achieved.

Originality/value

The authors have studied the combined effect of different weft yarn materials with different picking sequences and different weave designs on thermal conductivity of the woven fabrics.

Abstract

Purpose

Eri silk fiber has superior thermal insulation behavior, better softness than cotton fiber. However, Eri silk’s use in the commercial arena has not yet taken off. The purpose of the study is to explore the comfort properties of the fabric, which enhances the commercial acceptance of Eri silk clothing.

Design/methodology/approach

In this investigation, three different single knit Eri silk structures were produced with different loop lengths and yarn counts to analyze the influence of process variables on low-stress mechanical properties. To execute the research work, Eri silk spun yarn of three different linear densities (15 tex, 20 tex, 25 tex) were chosen. Three different knitted structures were produced, such as single jersey, popcorn and cellular blister, and two different loop lengths were also selected.

Findings

The cellular blister structure has shown appreciable low-stress properties next highest position was attained by the popcorn structure. Yarn fineness and loop length were significant with most of the low-stress properties.

Research limitations/implications

The findings of this research will contribute to a greater awareness of Eri silk knitted fabric and its process parameters in relation to its commercial utility.

Originality/value

This study was conducted to explore the influence of knit structure, loop length and yarn count on the low-stress properties of Eri silk-based thermal clothing.
