The review provides an overview of research findings on microencapsulation for functional textile coatings. Methods the preparation microcapsules in textiles include situ and interfacial polymerization, simple complex coacervation, molecular inclusion solvent evaporation from emulsions. Binders play a crucial role coating formulations. Acrylic polyurethane binders are commonly used finishing, while organic acids catalysts can be chemical grafting as crosslinkers between cotton fibres. Most...

The interest in pH-sensitive textile sensors is growing the global market. Due to their low-cost production, mechanical stability, flexibility, air-permeability, washability, and reusability, they are more suitable than electronic sensor systems. research tailored by applying pH indicator methyl orange cotton fabric during conventional dyeing. Adsorption of dye hindered due electrostatic repulsive forces between anions negatively charged fibre. To overcome this problem, chemical modification...

In this study, a novel green process was developed to produce multifunctional cotton (CO) fabric incorporating TiO2/curcumin composites that simultaneously provides UV protection and photocatalytic performance. For purpose, TiO2 synthesised using the sol–gel process; loaded with natural colourant curcumin as visible light absorber at two temperatures, i.e., 70 350 °C; applied CO via pad–dry–cure process. comparison, without under same conditions. The synthesis conditions °C ensured formation...

The chemical composition of rainwater can serve as an indicator the excess acidifying air pollutants. pH value in presence sulphur dioxide and nitrogen oxides, precursors acid rain, falls below 5.6, which is limit for rain. In this research, tailoring halochromic textile was examined design a functional that sensor inform wearer about pollutants by means immediate colour change. For purpose, polyamide 6 fabric dyed with pH-sensitive Bromocresol green dye, causes change 3.6 (yellow) above 5.4...

Cotton fabric was exposed to low-pressure capacitively coupled plasma enhance the adsorption and adhesion of fragrance microcapsules (FCM). Two plasma-forming gases, namely oxygen (O2) nitrogen (N2), were investigated. The untreated plasma-treated samples investigated for their morphological changes by scanning electron microscopy (SEM), mechanical properties (breaking force, elongation, flexural rigidity), wicking properties. cotton functionalized with FCM effect pretreatment on evaluated...

Commercial microencapsulated photoresponsive dye was applied on cotton, polyester/cotton and polyester fabric using a pad‐dry‐cure process. Colour fastness of the fabrics to washing, wet cleaning, dry rubbing light investigated. The CIELAB colour values before after testing were measured reflectance spectrophotometer, differences calculated evaluate properties. had better cleaning washing than cleaning. showed higher rubbing. photoresponsiveness decreased with prolonged exposure time...

The weak photostability of photochromic dyes applied to textile substrates is one the disadvantages broader use in industry. Therefore, influence optical brightener concentration on both photocoloration and cotton fabric coated with microcapsules using a pad-dry-cure process, as well physical-mechanical properties colorfastness properties, were studied this research. Coated samples subjected different tests according valid EN ISO standards; namely mass per unit area, stiffness, breaking...

The infl uence of the treatment process on dyeability cotton fabric with a natural dye from goldenrod blooms was studied in this research.The dyeing performed untreated and treated samples.The treating samples, using mordant (KAl(SO 4 ) 2 × 12 H O), before during process, whilst cationic agent (Denimcol FIX-OS) only dyeing.The carried out at 60 °C two repetitions three diff erent concentrations aqueous extract, namely without dilution, by diluting extract distilled water volume ratios 1:2...

This work examines the possibility of using leaves from invasive plant species Fallopia japonica (Japanese knotweed) as a source dye for natural dyeing cotton.To achieve higher uptake extracted dye, cationic agent instead classical mordant was used to treat cotton prior dyeing.Distilled water and 0.5 M NaOH were extraction mediums produce dyebaths with diff erent concentrations (10, 20 50 g/L) leaves.The colorimetric measurements revealed that concentration extract, in pretreatment yield...

Introductione mechanisms of surfactants working as levelling agents during reactive wool dyeing have received much attention over recent years due to skittery [1], which represents a serious technological problem.Surface active (surfactants) used can be dye-or bre-substantive regarding their ionic activities.Non-ionic are usually dye-substantive and form water-soluble dye-surfactant complexes in the dyebath, whereas

The development of pH-responsive textile sensors has attracted much interest in recent decades. Therefore, the aim this study was to show that screen printing could be one possible techniques for textile. Several parameters influence pH sensitivity and responsivity a screen-printed with bromocresol green dye were studied, such as substrate (cotton, polyamide), paste composition, type fixation (heat steaming). change mechanical physical properties printed fabrics tested according valid ISO,...
