Content available remote Multifunctional Finishing of Cotton Fabric
EN
The research in textiles is being driven by ecology, economy, and functionality. Therefore, the present research is focused on the development of multifunctional textiles that consume minimum energy during their processing, eco-friendly chemicals for functionalization, and use short processing steps. Eco-friendly cross-linkers such as butanetetracarboxylic acid and zinc oxide nanoparticles are used to impart wrinkle recovery, antibacterial activity, ultraviolet (UV) protection, bending rigidity, and antistatic properties to cotton fabric just in one step. The treated fabric has been characterized with Fourier-transform infrared spectrophotometer, scanning electron microscope, and X-ray diffractometer. Wrinkle recovery, tear strength, antibacterial activity, UV protection, and antistatic properties were tested with AATCC 66-1990, ASTM D 1224, AATCC 147, AATCC 183, and UNI EN 1149, respectively. The treated fabric shows excellent functional properties up to 20 washing cycles.

In this study, the possible improvement of the antibacterial and wrinkle resistance performance of 100% nettle fabrics was investigated. To realise this aim, antibacterial and wrinkle resistance finishing processes were applied. 1,2,3,4-Butanetetracarboxylic acid (BTCA) and sodium hypophosphite (SHP) were used to impart the wrinkle resistance property. Moreover chitosan was incorporated in the finishing bath for the antibacterial property. The effects of respective treatments on the physical properties were determined and compared along with their antibacterial activity. BTCA concentration in the solutions influenced the physical properties of the nettle fabrics and 6% BTCA usage was found to be the optimum concentration rate. The addition of BTCA to the chitosan caused an improvement in the wrinkle resistance and slightly softer handle, in comparison with pure chitosan treatment; however, the strength loss slightly increased, as expected. The FTIR-ATR spectra showed a new peak that confirmed the ester linkage formation and crosslinking reaction.

W pracy zbadano właściwości antybakteryjne i odporność na gniecenie tkanin otrzymanych z włókien pokrzywy. W celu nadania tkaninom odporność na gniecenie użyto kwasu 1,2,3,4-butanotetrakarboksylowego (BTCA) i podfosforynu sodu (SHP). Ponadto w celu podwyższenia właściwości antybakteryjnych tkanin do kąpieli wykończeniowej dodano chitozan. Dodanie BTCA spowodowało poprawę odporności na gniecenie i delikatniejszy chwyt tkaniny, jednakże poskutkowało spadkiem wytrzymałości, w porównaniu do tkaniny z pokrzyw niepoddanej obróbce. Tkanina wykończona kombinacją chitozanu, BTCA i SHP wykazała odpowiednią odporność na gniecenie, wytrzymałość na rozciąganie i delikatny chwyt wraz z poprawioną aktywnością antybakteryjną.

This study evaluates the wrinkle behaviour and wrinkle resistant properties of cotton fabrics dyed by Direct Blue 2B in the presence and absence of nano-TiO2 particles. A finishing process on samples was performed before dyeing by means of 1,2,3,4-butanetetracarboxylic acid (BTCA) and sodium hypophosphite (SHP) using a pad dry cure method. Such experiments as wrinkle recovery test (AATCC-128), water drop test and dye fastness determination (ISO 105-C01) were conducted to understand how current treatment impacted the cotton fabrics’ properties. Finally, samples were characterised using the X-ray diffractometery method to scrutinise how crystallinity changes and dominates the structural parameter (wrinkle behaviour) of cotton fabrics. Furthermore, scanning electron microscopy (SEM) was used to visualise the surface variations of the samples before and after dyeing process. The results showed that the wrinkle resistant of cross-linked fabrics have been improved after direct dyeing. Furthermore, levelness dyeing and good fastness properties of dyes on cross-linked fabrics were observed.

Content available remote Formaldehyde Free Binding System for Flame Retardant Finishing of Cotton Fabrics
EN
The promising application of citric acid (CA) and 1,2,3,4-butanetetracarboxylic acid (BTCA) for the purpose of flame retardant (FR) finishing was investigated. Both polycarboxylic acids (PCAs) were applied as an environmentally friendly binder in a reaction with N-hydroxymethyl-3-dimethylphosphonpropionamide. The results were compared with a conventional agent based on melamine formaldehyde. The purpose of melamine resin is to provide nitrogen in order to enhance the flame retarding performance of the treated fabric through synergism with phosphorus. In our previous investigations it was determined that the best catalyst to be used with PCAs is sodium hypophosphite monohydrate (SHP). The FR effectiveness was tested according to the ISO 6940 method, as well as with the limiting oxygen index (LOI) technique according to ASTM D 2863-97. Moreover, the thermal degradation of raw cotton and FR treated cotton fabrics was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).

Badano zastosowanie kwasu cytrynowego i 1,2,3,4-butanotetrakarboksylowego (BTCA) w celu uzyskania anytpalnej preparacji. Obydwa kwasy polikarboksylowe zastosowano jako przyjazne środowisku związki wchodzące w reakcje z 3-dimetylofosfopropionoamidem. Wyniki porównano z konwencjonalną preparacją z udziałem formaldehydu melaminy. Celem zastosowania żywicy melaminowej jest wprowadzenie azotu w celu zwiększenia niepalności. Antypalność materiałów badano zgodnie z normą ISO 6940, jak również metodą Ograniczonego Indeksu Tlenowego (LOI) zgodnie z normą ASTM D 2863-97. Dodatkowo obrabiane materiały poddano analizie termo grawimetrycznej oraz różnicowej kalorymetrii skaningowej.
