In recent years, environmental problems such as global warming, in which the average temperature of the earth s atmosphere rises due to the greenhouse effect, abnormal climate, byproducts from production activities, and the shortage of future conservational resources due to the increase in consumption have become global issues. In Korea, phenomena such as yellow dust, fine dust, and air pollution, which are directly related to public health, are emerging as social problems and attracting attention as a sustainable topic. Along with efforts to preserve the environment, technology development for ecofriendly textiles continues to improves in the field of textiles. In this study, to address the global textile industry s desire for sustainability, a bionic nylon material combined with a collagen peptide extracted from marine waste was selected, and R&D was conducted for various commercializations. This study was conducted to investigate the dyeability of circular knitted bionic nylon fabrics, as well as to determine the effect of scouring properties as a function of scouring agent concentration and dyeing properties as a function of dye type, dye concentration, dyeing temperature, and dyeing time on the dyeability of bionic nylon.

Antibacterial, Scalable Manufacturing, Skin-Attachable, and Eco-Friendly Fabric Triboelectric Nanogenerators for Self-Powered Sensing

Textile-based triboelectric nanogenerators (T-TENGs) are an indispensable cornerstone of new wearable electronics. However, the manufacturing processes of T-TENGs usually involve complex chemical processes and expensive materials. The friction materials utilized in these T-TENGs generally come from nonrenewable resources. Here, we report the development of the scalable fabrication of a flexible, skin-attachable, and eco-friendly fabric triboelectric nanogenerator (FTENG) with satisfactory comfort and excellent antibacterial properties by introducing eco-friendly green materials, Tencel and chitosan fibers. The yarn triboelectric nanogenerator (YTENG) fabricated by a scalable fancy yarn spinning technology using Tencel and chitosan fibers exhibits high flexibility, small diameter, low weight, high scalability, and productivity as well as low cost, which contribute to the widespread application of T-TENGs. Benefiting from the excellent compatibility of YTENGs, automatic weaving for producing such FTENGs is demonstrated. The output voltage, current, and power density of a fabricated FTENG operating at a single-electrode mode can reach 31.3 V, 1.8 μA, and 15.8 mW/m2, respectively, by applying a 3 Hz mechanical drive of 100 N with a size of 5 × 5 cm2. Such FTENGs have been used as self-powered sensors for body motion monitoring. This study presents a novel and sustainable strategy for the development of eco-friendly T-TENGs.

Analysis of Motivational Conditions Behind Sustainable Consumption in China’s Uniform Market

A uniform is distinctive clothing worn by members of the same firm or organisation. In China, the market for professional garments is extremely large. However, as mandatory professional clothing, uniforms are frequently used, torn, and replaced, leading to textile waste. Further, the use of non-recyclable or non-biodegradable fabrics is bound to create greater environmental pressure. This study focuses on the textile material in the uniform market to analyse the motivational conditions behind sustainable fabric consumption. A total of 294 usable online surveys were obtained in 2019. Multi-item scales were adopted to measure five variables: corporate public image, corporate ethics, employee social status, environment awareness, and sustainable premium. Structural equation modelling was applied to test the hypothesises. Results reveal that the improvement of an employee’s social status can effectively facilitate the probability of utilising eco-friendly fabrics. This study can thus help increase the usage of eco-friendly fabric in China’s uniform market.

Hydrogel bacterial cellulose: a path to improved materials for new eco-friendly textiles

In this paper, we present a novel, ecologically friendly technology for the synthesis and modification of kombucha-derived bacterial cellulose in order to produce textiles of desired physicochemical and mechanical properties. The procedure of manufacturing cellulose in the form of a stable hydrogel bacterial cellulose (HGBC) ensures the desired properties for the application of such a material, e.g., in the textile industry. Bacterial cellulose was obtained from a yeast/bacteria kombucha culture (a symbiotic consortium also known as “tea fungus” or SCOBY) that is easy and cheap to breed. The process of bacterial cellulose manufacturing and modification was optimized in order to obtain a maximum recovery of raw materials, minimal energy consumption and ensure the use of only natural and renewable resources. The obtained materials were characterized in terms of their wettability, mechanical properties, and flame resistance. Moreover, the morphology and composition of the materials were determined by using scanning electron microscopy and infrared spectroscopy, respectively. Additionally, it was proven that the HGBC materials might be used to manufacture various articles of clothing using commonly available sewing techniques, which are not adequate for non-modified cellulose-based materials. Finally, the synthesized fabrics were used as wristbands and parts of T-shirts and tested on volunteers to determine a skin-to-skin contact behaviour of the prepared fabrics. The reported results allow for confirming that the HGBC fabric may be used as a new textile and the proposed synthesis method is in accordance with the “green chemistry.”Graphic abstract

UV-protection property of Eri silk fabric dyed with natural dyes for eco-friendly textiles

Eri silk (Samia ricini) is a wild silkmoth which has been promoted and supported to culture for textile industry in Thailand. Especially for the recent decade, textile industry was interested to develop eri silk for casual eco-friendly textile style with functional properties. This research aims to study on UV protection property of eri silk fabric dyed with natural dyes from plant extracts and their washing fastness property. The processes included extracting the colorants from Thai plants i.e. natural indigo, Burma padauk bark, Neem bark, etc., mordanting the eri silk yarn with potassium aluminum sulphate, iron (II) sulfate and dyeing with their natural dyes to increase the washing fastness property. Eri silk fabrics were woven by the dyed eri yarn providing an excellent protection (UPF 50+) with a proper shade for making 3 prototype clothing products. The result shows that UPF property of eri silk fabric dyed with Burma padauk bark, Gloden shower seed, Neem bark, Andaman satinwood leave and mordanted with iron (II) sulfate presented highest UPF (>100) with good washing fastness. Three prototype products were designed with color matching with natural dyes and fabricated which were hat, scarf and dress. The first product, hat, made from the hand-weave fabric comprised of Ne 20/2 eri spun silk yarn as a warp yarn and Ne 20/2 eri spun silk yarn that dyed from Burma padauk bark as weft yarns. Second product was scarf which made from Ne 20/2 eri spun silk yarn as a warp yarn and Ne1.2 eri hand-reel silk yarn dyed from natural indigo and Burma padauk bark as weft yarns. The last product was dress which made from Ne 30/2 eri spun silk yarn that dyed from sappen as a warp yarn and Ne 30/2 eri spun silk yarn that dyed from indigo as weft yarns. These eco-friendly eri silk products exhibited excellent functional UV-protection property.

Measuring Saudi Mothers’ Awareness of Sustainable Children’s Clothing

A mother begins to care about her baby once she learns about her pregnancy. She becomes even more concerned about her baby after delivery, and, therefore, starts to scrutinize everything that is of interest to the baby, including the selection of adequate clothing that is not harmful to sensitive skin. Given the importance of providing comfortable and healthy clothing to our children, it was necessary to focus on the type of fabrics from which children’s dresses are made. Also there has been a need to understand the best characteristics and specifications of fabrics, as sustainable fibers that are made from cotton are commonly preferred over synthetic fibers which are considered unsuitable for children due to the sensitivity of their skin. With the beginning of the 21st century, fast fashion has become a source of growth, and production of clothing doubled dramatically. Estimates indicate that consumers are turning to cheaper clothes which are usually discarded after a short time, while ignoring sustainable fabrics and quality of clothing, thus harming the children’s skin. Based on this fact, this research seeks to examine Saudi mothers’ awareness of sustainable fabrics, their interest in purchasing eco-friendly children’s clothing as well as their purchasing preferences of children clothing. This paper also seeks to raise awareness among mothers on the importance of choosing sustainable fabrics for children’s clothing, guide mothers to opt for quality of fabrics over designs, encourage designers to create designs for children’s clothing using eco-friendly fabrics, and encourage merchants to use and market eco-friendly fabrics in order to reduce the environmental pollution, in line with the Saudi Vision 2030.

Investigation of tensile strength and elongation properties of chenille upholstery fabrics including recycling polyester yarns

Every day, millions of plastic and polyethylene terephthalate bottles are being thrown away by people. This leads not only to the reduction of landfills and increase in environmental problems but also to pollution of marine and oceans that affect the lives of many living things. Therefore, recycling of waste polyethylene terephthalate bottles with recycling technologies has great environmental importance. In this study, recycled polyester yarns obtained by recycling waste polyethylene terephthalate bottles and standard polyester yarns were used in staple forms, as well as binder and pile yarns of the chenille yarn structure. In this context, 16 different chenille yarns were produced and the production parameters such as rotor speed, spindle speed, and pile density are kept constant by selecting the appropriate values. Then, these chenille yarns were used as weft to produce upholstery fabrics. Tensile strength and elongation tests were applied to the upholstery fabrics, and the results were evaluated statistically. As a result of the tensile strength tests and statistical analyses, it is concluded that the weft breaking strength of all types of woven fabrics, which have 100% recycled polyester in the structures of chenille yarns as weft, is slightly decreased compared to other types, but this decrease is not statistically significant. The use of recycled polyester yarns in the structures of chenille yarns, which are widely used in the upholstery sector, will be beneficial in producing more sustainable and eco-friendly fabrics.

Terminalia arjuna Dyed Woolen Yarn - Effect of Binary and Ternary Metal Salt Combinations: A Greener Route for Production of Ecofriendly Textiles

ABSTRACT Terminalia arjuna(Roxb.) Wight and Arn. (family: Combretaceae) is a large evergreen cardioactive plant drug available throughout India. The bark of T. arjuna is medicinally used as a tonic and is chemically characterized by the presence of tannins and related compounds with 20.0–24.0% tannin content. This research study investigates the use of barks of T. arjuna for the extraction of color components to develop natural and beautiful shades on wool with different hues and tones using binary and ternary metal salt combinations (aluminum potassium sulfate, ferrous sulfate, and stannous chloride). The dyeing was carried by exhaustion method and dyed samples were analyzed using a reflective spectrophotometer in terms of CIELAB (L*, a*, and b*) and color strength (K/S) values. Wash and light fastnesses were investigated according to (International Organization for Standardization)ISO standards. pH has marked effect on the K/S values of dyed woolen yarn. The results showed that overall 54 different shades having good to very good fastness properties were produced by control dyeing (un-mordanted) and the use of different metallic salt combinations in dyeing of wool using T. arjuna bark extract as a source of natural dye.

Coloration, UV Protective, and Antioxidant Finishing of Wool Fabric Via Natural Dye Extracts: Cleaner Production of Bioactive Textiles

Biocompatibility and biodegradability of natural compounds attracted researchers to utilize them toward healthy environment, and so for the production of ecofriendly textiles. The present study reports a cleaner production approach to develop bioactive textiles via the application of Acacia nilotica, Terminalia arjuna, and Adhatoda vasica natural dyes. Colorimetric characteristics, sun protection and antioxidant properties of bioactive wool fabrics have been evaluated. Evaluation of these characteristics with the effect of iron pre‐mordanting was also assessed. A broad range color palette is obtained with good fastness results to washing and rubbing. Sun protection properties of developed bioactive wool fabrics were assessed in terms of ultraviolet protection factor (UPF) and UV transmittance in ultra‐violet region (UV‐A and UV‐B), relative to un‐dyed wool fabrics. Antioxidant properties of developed wool fabric were determined in terms of % inhibition of peroxidation by ABTS (2,2′‐Azino‐bis(3‐ethylbenzothiazoline‐6‐sulphonic acid)) radical scavenging activity. Transmittance values of <5% and >40% inhibition of peroxidation demonstrates the use of promising natural multifunctional finishing agents from A. nilotica, T. arjuna, and A. vasica natural dyes for the development of bioactive textile fabrics. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

Biofunctional wool using β-cyclodextrins as vehiculizer of citronella oil

Abstract The use of biopolymers such as cyclodextrin in textiles for the development of biofunctional fabrics is an alternative for the development of eco-friendly textiles. Cyclodextrins can create covalent interactions with the chemical groups available in wool, allowing the sorption of active molecules that will be released, such as the citronella oil. Therefore, this work investigates the formation of cyclodextrin complex oil applied in wool and its release mechanism. The complexes obtained and grafted to the fabric. New microstructures formed have been characterized using instruments as TGA, DLS, FTIR-ATR and SEM, besides the verification of the durability of the finish and the cytotoxicity of the obtained fabric. The release of citronella oil was, also analyzed and mathematical adjustments were performed using the approach proposed by Korsmeyer-Peppas in order to verify the release mechanisms. Results have indicated the formation of the complex and its fixation by covalent bonding, according to the FTIR-ATR specter and SEM images, have shown an non-fickian, but controlled, release profile. For this reason, the application of the complexes in wool fabrics shows promising options for the design and production of eco-friendly biofunctional materials for controlled release, allowing the oil properties to be used in textile matrices.

Phytic acid as an eco-friendly flame retardant for silk/wool blend: A comparative study with fluorotitanate and fluorozirconate

Abstract Because of the urgent needs for eco-friendly textiles and environmental protection, the development and application of sustainable flame retardant (FR) agents have become a research hotspot. In this work, naturally occurring and phosphorus-rich phytic acid (PA) was used to improve the FR ability of silk/wool blend using an adsorption technique, and comparative studies were conducted on the application conditions, FR effect, smoke suppression, heat release capability, catalytic char forming, and FR mechanism of PA and conventional FR agents (K2TiF6 and K2ZrF6). The application of PA at pH 1.3–2.0, moderate temperature, and proper concentration remarkably improved the FR ability of the blend as per the limiting oxygen index and vertical burning assessments. Although the PA treated blend was inferior to the K2TiF6 treated blend in initial FR ability, it exhibited better FR effect after repeated washing. Among three FR agents used, PA had the best smoke suppression, lowest heat release capability, highest ability to inhibit the thermal oxidation of the degraded products of fibers, and best catalytic char forming effect. PA acted as an effective FR in the solid phase. However, the application of PA had a shortcoming of decreasing the whiteness of the blend.
