In recent years, studies have focused on the development of fire retardant products that are produced without the use of flame retardants with toxic effects and do not have harmful effects on humans and the environment. In this work, it has been compared the flame retardant properties of some biodegradable fibers obtained from different sources. It is important to investigate the performance of textile surfaces obtained from renewable fibers for flame retardant products and to improve their usage possibilities. The fire retardancy properties of knitted fabrics containing PLA, cotton, lyocell, and chitosan fibers were studied by analyzing the LOI values and burning behaviors. Single jersey knitted fabrics composed of 100% PLA, 100% Lyocell, 95% PLA 5% Chitosan, 95% Cotton 5% Chitosan, 95% Lyocell 5%Chitosan, 80%PLA 15%Cotton 5%Chitosan, 80%PLA 15%Lyocell 5%Chitosan were produced. The flame speed of each material was determined and differences in the flammability behaviors of the fabrics were identified. The lowest flammability occurred for the fabric 95% PLA and 5% Chitosan. The highest flammability was for 100% Lyocell knitted fabric. Knitted textile structures were evaluated for their flammability using the standard fire test ISO 6941. Also, the limiting oxygen index (LOI) of knitted fabrics under ASTM: D2863 was evaluated.

Biotechnology and eco-friendly technologies (ultrasound, ultraviolet, ozone, etc.) called as green chemistry play an important role in the field of environmental protection. In this study, the desizing and bio-scouring of greige woven linen fabrics with commercial enzymes in the one bath was performed by the aid of ultrasound energy. The five factors with three levels Box–Behnken response surface experimental design was chosen to study and optimize the influence of process variables, such as amylase concentration (0–1 g/L), laccase concentration (0–1 g/L), pectinase concentration (0–1 g/L), sonication time (20–60 min) and treatment temperature (30–70 °C), on the whiteness, lightness, weight loss and hydrophility properties of linen samples. The regression model provided an excellent explanation of the relationship among the independent variables and the response. The achieved results indicated that the efficiency of desizing and bio-scouring could be remarkably improved by the aid of ultrasound energy. Also enzymatic & ultrasonic pretreatment of linen fabrics provides thermal energy, time and chemical savings. The results obtained confirm that enzymatic & ultrasonic bio-scouring of linen fabric can be performed in three different ways depending on the required properties.

It has been seen that the approaches related to green-manufacturing have significant role in textile industries upon improvement of awareness on environmentally friendly point of view. Environmental impacts of the material should be taken into consideration for improving new textile structures. Materials should be composed of environmentally friendly raw material and the harmful emissions of whole production processes should be limited, while the material should be easily disposable with no detrimental effects on the environment after use. The aim of this study is to develop textile structures which have sustainable, environmentally friendly and functional characteristics. Antibacterial knitted fabrics have been improved in this study. Raw materials were selected among environmentally friendly new generation fibers. PLA (Polylactic acid), lyocell and chitosan fibers were mixed, the single jersey knitted fabric composed of 80% PLA 15% Lyocell 5% Chitosan having thickness of 30/1 were produced. Production processes which minimize harmful emissions to the environment were used. Antibacterial efficiency of the designed fabric was tested according to AATCC100. In addition, biodegradation of the improved knitted fabric was tested in soil burial test under standardized laboratory conditions for a defined test period of 4, 12 and 24 weeks. After soil burial test, the ecotoxicological assessment of soil was performed with plants growth test.

This article is about bleaching of soybean fibers. Although the studies related to dyeing of soybean fibers have been found in the literature, little has been reported on the effect of bleaching. The natural color of soybean protein fibers is pale yellow or cream, and it is therefore usually necessary to bleach them to improve their whiteness. Different bleaching treatments combined with ozonation were performed in order to establish the effect on whiteness, yellowness, lightness, wettability, hydrophility, moisture sorption, and fiber damage properties of knitted soybean fabric. As a result of study, bleaching process combined with ozonation (ozonation + oxidative bleaching + reductive bleaching) supplied soybean fabric with a white appearance (highest whiteness degree), highest hydrophility, and minimal fiber damage.

In this study, ozonation as an environmentally friendly bleaching method was studied for decolorization of leather products. The effect of ozonation time (3, 5, 10, 15 and 30 min) and water pick-up value (WPV) (0%, 20%, 40%, 60%, 80% and 100%) were investigated on decolorization effect. For this aim, the color measurement and tensile strength tests were performed, and also structural changes were determined by scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) after ozonation process. The results of color measurements showed that 30 min for ozonation and 60% WPV were optimum parameters to obtain maximum decolorization effect. SEM images of the ozonated leathers showed some deformations on the collagen fibers and resulted with the slightly decreases in tensile strength of the products. On the other hand, decreases in the tensile strength values were not statistically important levels.

It is well known that ozone can be used as a bleaching agent for cellulosic textile materials. In the context of this study, investigations were undertaken to optimize bleaching of linen fabrics using Box-Behnken Experimental Design. The bleaching process involved two distinct steps where linen fabrics were ozonated under different treatment times then the latter in a subsequent step were subjected to hydrogen peroxide bleaching under a variety of conditions. As a result of study, three optimum recipes were achieved and pretreatment with ozone for 15 min before peroxide bleaching supplies time and chemical savings.

The aim of this study was to investigate the effects of novel treatment techniques (ozone and ultrasound) on the dyeability of Angora rabbit fiber.

This paper provides a general framework for studying the yellowing tendency of ozonated cotton fabric. Yellowing tendency of ozonated cotton fabric and ways to prevent this situation was examined extensively. For this purpose, five different treatments (hot/cold rinsing, washing, reductive washing, catalase treatment) were performed after ozonation. It was found that performing any kind of treatment was significantly important for preventing yellowing of ozonated cotton fabric during storage.

The aim of this study is to investigate the effects of new advanced processes (ultrasound, ozonation, and ultraviolet) on cotton woven fabric's hydrophility and polymerization degrees, breaking strengths, whiteness, and desizing degrees. For this purpose, all trials were realized with water at 63-65°C by the aid of advanced processes. At the end of the experiments, it was noticed that advanced processes can be used in pretreatment of cotton fabrics. Ultrasonic treatment followed by ozonation gives sufficient whiteness degrees and hydrophilily values to the fabric. At the same time, treatment of cotton fabrics with new processes provides savings of thermal energy, water, and chemicals. Moreover, these processes are considered as green processes because they are ecological in certain conditions when compared with conventional processes.

The aim of this Study was to investigate a novel bleaching technique for Angora rabbit fiber. For this purpose, a detailed investigation on the role of the fiber moisture, pH. and treatment time during ozonation was carried out. Also, the effect of ozonation on the dyeing properties of Angora rabbit fibers was researched. Consequently, it was found that ozonation improved the degree of whiteness and dyeability of Angora rabbit fiber. (C) 2008 Elsevier Ltd. Ail rights reserved.

Polymeric fibres are semicrystalline structures in which the macromolecules are rarely oriented in their equilibrium state. Further instabilities are imparted when the fibres are converted to yarns and the yarns to fabrics. Heat-setting is an important industrial process, as it reduces the fibre strain to an acceptable limit. This paper presents results of a study on the effects of various presettings (heat-, steam- and hot water-setting processes) on the dyeing properties of polyamide 6.6 fibres with acid dyestuffs. It was found that the colour yield is lower for dyed samples after dry heat-setting, but in the case of samples that have been hot water-set or steam-set, the colour yield increases slightly for light shades and remains constant for dark shades, compared with the unset dyed sample.

Wool is an outstanding, multifunctional natural fiber. Its physical and chemical structure makes it valuable since the ancient era of the humanity. However, preparing wool for end use is difficult and complicated, so it needs intensive care on every production step. Its treatment steps start while wool is on fleece form. Among those processes, scouring of raw wool fibers is a strenuous work. Besides this, it is the first step can influence the destiny of the wool for subsequent usages. As it is known, raw wool fleece includes contaminations which can weigh the half or more of the raw wool. Scouring process was managed firstly generally to terminate those impurities. In this study, the effect of ultrasound waves during scouring of raw wool fibers was examined. For this aim wool fleece was scoured consecutively in five washing steps with and without ultrasound. It was found that after third washing step in consecutively ultrasonic washing process, nearly same results provided by the five stepped non-ultrasonic washing regime. Addition to this, the fleece was also scoured separately in different temperatures with only water and with chemicals. Especially the washings at 50 C with ultrasound for 30 min in separate washing regimes was found as an alternative for the non-ultrasonic consecutively washings. On the other hand with the washings at 35 C with only water via ultrasound has shown interesting results too. In general it can be told that application of ultrasound in scouring processes provided improvements in washing efficiency. In other words, addition the ultrasound to scouring processes caused better whiteness degrees and removal of dirties. (C) 2012 Elsevier Ltd. All rights reserved.
