Effect of the particle size of fluorocarbon‐based finishing agents on fastness and color properties of 100% cotton knitted fabrics

This study examines the effect of the particle size of fluorocarbon‐based water‐oil‐soil‐repellent finishing agents on color fastness and colorimetric properties by experimental analyses. Therefore, two finishing agents with different particle sizes were applied to red‐dyed and blue‐dyed knitted fabric samples of single jersey and rib‐structured knits, produced from 100% cotton yarns. The results show that smaller particle size causes less color change for all washings (0, 1 and 5), both of the dyes and the fabric structures (single jersey and rib). Also, it is observed that smaller particle size positively affects the rub fastness results.

A new approach for simultaneous salt-free dyeing and functional finishing, i.e. UV protection and antibacterial properties of cotton fabric were studied. In this study, cotton fabric was cationized with 3-chloro-2-hydroxypropyl trimethylammonium chloride. Two types of reactive dyes (CI Reactive red 120 and CI Reactive yellow 145) were doped with different amounts (0.035, 0.053, and 0.07 mol) of TiO₂ nano-sol by sol–gel method and applied on cationized cotton fabric using pad–dry–steam method without the addition of salt. The chemical and morphological structures of the dyed fabrics were characterized by attenuated total reflection-Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, and X-ray diffractometry. Different properties were investigated such as color strength, fixation, fastness properties (washing, rubbing, and light), UV blocking, antibacterial activity, and tensile strength. Samples dyed with titanium dyeing solutions exhibited better antibacterial efficacy and durable UV protection, with minimal impact on color depth and tensile strength compared with the samples dyed with commercial reactive dyes.

Comfort properties of bamboo/cotton blended knitted fabrics produced from rotor spun yarns

The comfort characteristics of bamboo/cotton-blended knitted fabrics made from rotor-spun yarns were studied in this research work. Five different blend proportions namely 100% bamboo, 100% cotton, 50:50 cotton:bamboo, 70:30 cotton:bamboo and 30:70 cotton:bamboo were used to produce rotor-spun yarns of 30^sNe_c.

All the fabric samples were dyed and finished. Fabric samples were evaluated for geometrical properties such as course/inch, wales/inch, stitch density and thickness apart from measuring comfort properties such as airpermeability, thermal conductivity, thermal resistance and water vapour permeability. The results indicated that 50/50 bamboo/cotton-blended knits have comparable fabric quality in terms of comfort properties with respect to 100% bamboo fabrics.

A novel treatment for multifunctional finishing and reactive dyeing of polyamide‐6–cotton blend

A new approach to simultaneous functional finishing and reactive dyeing of polyamide‐6–cotton fabric (50/50) is developed. The extent of improvement in the functional and dyeing properties is determined by the UV‐absorber, UV‐Sun® CEL, concentration, type and concentration of the used reactive dye as well as the treatment sequence.

After 15 washing cycles, the depth of shades and the fastness properties of the obtained dyeings are not seriously affected. The incorporation of the used UV‐absorber onto the blend fibres was also confirmed by SEM analysis.

Dyeing of cotton fabric for improved mosquito repellency

Recently, mosquito repellent textile materials are increasingly in demand from consumers as a preventive measure from mosquito-borne diseases like malaria, dengue. Mosquito repellent-treated textile material initially shows good repellency against mosquitoes but upon repeated washing cycles this effect gets washed off considerably. In the present work, 4-Amino-N, N-diethyl–3-methyl benzamide (MD) is synthesized from N, N-diethyl-m-toluamide (DEET) and it is used as base material for synthesis of azo group. This synthesized base MD was then coupled with three different napthols to get dyed cotton fabric using diazotization process. This dyed cotton fabric has imparted mosquito repellent finish in one, single operation of dyeing cum finishing. This approach is based on modification of universally used mosquito repellent and synthesizing an azo group-based dye in the fibre matrix of the cotton fabric. The chemical structures of the MD were characterized using FT-IR and ¹H-NMR spectroscopy. The fastness properties of the dyed cum finished fabric were measured to evaluate the performance of the dyed fabric. Efficacy of mosquito repellency of the dyed cotton fabric was studied using standard methods. The dyed cotton fabric using napthols and MD showed very good and durable mosquito-repellent activity.
