Authors: Shen G T, Pavithra; Kumar M, Ramesh; Ahmed Qureshi, Sajid; Das, Subrata
Abstract: This study presents the design and development of an automated device to eliminate auxiliary selvedge in shuttleless
rapier looms, thereby reducing material waste and production costs. The device grasps, cuts, and suctions the protruding
weft ends after each pick insertion, effectively minimising selvedge formation without altering loom parameters.
Experimental results show a 62.5% reduction in yarn waste and associated costs, while the fabric retains comparable
properties in terms of yarn density, tensile strength, tearing strength, bursting strength, air permeability, dimensional
stability, and crimp percentage. The attachment also functions efficiently in jacquard fabric structures, demonstrating its
broader industrial applicability. The device provides a sustainable and cost-effective solution for modern textile production,
enhancing material efficiency without compromising fabric quality

Authors: Manigandan, G; Ramesh Babu, V; Kumar, V; Prakash, C
Abstract: This study investigates the thermal comfort and moisture management properties of knitted fabrics using two different pique
knit structures: single tuck pique and bell pique. The impact of knit structure on various geometric and comfort properties is
evaluated, including loop length, wales per inch, course per inch, tightness factor, bursting strength, fabric thickness, GSM,
fabric stretch, air permeability, warmth retention rate, thermal transmittance coefficient, thermal resistance, CLO, and moisture
management. To construct the fabrics, a yarn linear density of 24s Ne is used, and three different loop lengths (0.265 cm, 0.285
cm, and 0.305 cm) are tested for each knit structure. The goal of this research is to compare the performance of these two knit
structures and determine how they affect the comfort properties of the resulting fabrics. It is observed that the bell pique
structure exhibits better comfort properties than single tuck pique at two loop lengths, and it may help the fabric manufacturers
and designers in selecting the appropriate fabric structure based on the desired comfort properties

Authors: Yangzom, Tsering
Abstract: The Himalayan stinging nettle (Urtica parviflora) remains an underutilised natural resource in Sikkim, with limited
research exploring its fibre potential. This study introduces a novel application of nettle bast fibres for the development of
bacterial transport swabs — a first of its kind globally. Nettle fibres are extracted through retting and enzymatic bioscouring,
followed by detailed characterisation using SEM, FTIR and TGA analyses. Swabs fabricated from these fibres are evaluated
for absorption capacity and validated through qualitative (roll-plate) and quantitative (swab elution) bacterial recovery tests
against standard cotton and viscose swabs. The results reveal that nettle fibre swabs perform comparably to cotton and
viscose in terms of bacterial recovery and absorption efficiency. Additionally, nettle offers advantages of renewability,
biodegradability, and low production cost. The findings highlight nettle fibre as a promising sustainable alternative for
microbiological transport swabs, combining functional performance with environmental and economic benefits

Authors: Narayan Saha, Rudra; Datta Roy, Manas; Ghosh, Subrata
Abstract: This study investigates the effects of braided samples composed of polyester filament yarns simultaneously for variables
like braid structure (1/1 and 2/2) and take-up rate on braiding angle, braid diameter, braid fineness, pick count, pitch length,
total mass, tensile strength, elongation and bending stiffness. This study indicates how changes in braid pattern and take-up
rate affect the mechanical properties of polyester tubular braided structures. The braiding machine's take-up speed directly
impacts the braid's formation speed, and it is possible to modify this speed without affecting the carriers' sequential motion.
To determine the significance of the difference in results, statistical analysis is performed at each state of observation.
