Noise pollution is one of the most pressing issues in our society today. Controlling noise has become one of the most essential and prevalent factors in the development of acoustic materials. Traditionally, numerous expensive and synthetic sound-absorption materials, such as glass fibre, carbon fibre and polymer fibres were utilised to suppress noise, posing additional harm to living organisms and the environment. Natural fibres derived from renewable resources can be utilised as sound-absorption materials that are inexpensive, bio-degradable, recyclable and readily available. Natural fibre-reinforced composites are currently exclusively used for diverse applications in the automobile industry, construction, building sectors, furniture and other industries. The risk of physical harm and health issues has been greatly reduced by adopting these natural fibre materials. In this research, an attempt has been made to manufacture composites from four natural fibres: hemp, bagasse, Arenga pinnata and bamboo. These four natural fibres were mixed in a 50:50 proportion along with polypropylene and developed into a textile composite using the thermal bonding method. The developed natural composite materials were tested for sound-absorption co-efficient using the impedance tube method and various physical properties, such as flexural rigidity, thickness, tensile strength, elongation, areal density, air permeability and thermal conductivity, were analysed for the composites using the standard testing procedures. All the possible influential factors that determine the acoustic characteristics property of the fibres are taken into consideration for the enhancement of the acoustic absorption of the composites. The sound-absorption co-efficient percent of the Arenga pinnata/polypropylene composite sample is higher than other fibres.

In order to impart good application properties to locust bean gum size for all-polyester yarn, a series of acrylate monomers including methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, and common hydrophilic monomer–acrylic acid were grafted onto molecular chains of native locust bean gum to obtain locust bean gum-g-P(AA-co-acrylate) products with similar grafting ratios through Fenton’s reagent, respectively. The effects of carbon chain length of the series of acrylates on sizing properties of the grafted locust bean gum for polyester warp were studied. It was found that by grafting acrylates onto the molecular chains of locust bean gum the sizing properties of the locust bean gum were improved markedly. Under the condition of similar grafting ratios, locust bean gum-g-poly(AA-co-methyl acrylate) showed the highest apparent viscosity, water solubility, film strength, wettability, and adhesion to polyester fiber in all the grafted locust bean gum prepared. Meanwhile, locust bean gum-g-poly(AA-co-butyl acrylate) and locust bean gum-g-poly(AA-co-2-ethylhexyl acrylate) had the highest wear resistance and elongation of sizing film, respectively. The modified locust bean gum grafted with acrylate monomers with different carbon chain lengths was able to meet various requirements in the sizing process for polyester yarn.
为了使刺槐豆胶浆料在全涤纶纱线中具有良好的应用性能，通过Fenton试剂将丙烯酸甲酯、丙烯酸乙酯、丙烯酸丁酯、丙烯酸2-乙基己酯和普通亲水性单体丙烯酸接枝到本地刺槐豆胶的分子链上，分别得到接枝率相近的刺槐豆胶-g- p (aa -共丙烯酸酯)产物。研究了丙烯酸酯系列碳链长度对接枝刺槐豆胶涤纶经纱上浆性能的影响。结果表明，通过在刺槐豆胶分子链上接枝丙烯酸酯，可以明显改善刺槐豆胶的上浆性能。在相同接枝率的条件下，皂荚胶-g-聚丙烯酸甲酯(AA-co-methyl acrylate)的表观粘度、水溶性、成膜强度、润湿性和对聚酯纤维的粘附性在所有制备的皂荚胶中最高。同时，皂荚胶聚(aa -co-2-乙基丙烯酸丁酯)和皂荚胶聚(aa -co-2-乙基丙烯酸己酯)的施胶膜耐磨性和伸长率最高。改性刺槐豆胶接枝不同碳链长度的丙烯酸酯单体，能够满足涤纶纱上浆工艺的各种要求。

Clothing and bedding that are labeled as “wrinkle-free,” “iron-free,” or “easy-care” use formaldehyde resins that can release a significant amount of formaldehyde. For patients who are allergic to formaldehyde, this can trigger allergic contact dermatitis. Unlike many other countries, formaldehyde levels in clothing are not regulated in the United States. The purpose of this study is to measure the amount of formaldehyde released from a variety of men’s dress shirts, women’s clothing, children’s clothing, and pillowcases, before washing and after washing using a Rotawash. This study has also looked at whether the price of an item has any correlation with the amount of formaldehyde released.

Blue-green algae is an environmental problem; they reproduce rapidly and threaten aquatic ecosystems. Therefore, research on their use as a new energy resource is being actively conducted in various fields. This study was carried out to apply the natural dye from blue-green algae to the textile dyeing industry. Two methods were used to dye cotton and silk fabrics using blue phycocyanin dye extracted from blue-green algae. Six mordants were also tested in the process. The dyed fabrics were evaluated through dyeing depth and color fastness (washing, rubbing, dry cleaning, and light) tests. Phycocyanin dyed both fabrics blue and the dyeing effect was better on silk than on cotton fabric. In addition, Al, Sn, and Fe mordants were most effective for dyeing fabrics and co-mordants were more effective than pre-mordants.

The source for reactive dye transfer of cotton fabric varies in different studies, and there is limited information on the washing factors. This study explored the source of Reactive Red 195 colored cotton fabric dye transfer and reported the effects of three key washing factors and their interactions with two types of dye transfer inhibitors. First, the high-performance liquid chromatography results show that the peak of completely hydrolyzed Reactive Red 195 matches the peak of the washing residue of the fabric colored by Reactive Red 195. The dye transfer process is positively related to the hydrolyzed dyes. Based on this, response surface method models for the three factors, water consumption, water hardness, and dye transfer inhibitors concentration for polyvinylpyrrolidone and lauryl betaine were built. Both response surface method models show that due to the presence of Ca2+ and Mg2+, the increase in water hardness reduces the zeta potential on the fabric surface, and causes a decrease of electrostatic repulsion between the dye and the fabric. The dye transfer inhibiting effect is reduced. The increase in dye transfer inhibitor concentration strengthened the effect of inhibiting the transfer of hydrolyzed Reactive Red 195. In addition, there is a cross effect between water hardness and dye transfer inhibitor concentration. There is optimal water hardness and dye transfer inhibitor concentration to maximize the inhibition of hydrolyzed Reactive Red 195 dye transfer. The water consumption shows a limited effect because the washing time is long enough to reach a balance in the fabric and washing fluids. Polyvinylpyrrolidone with many hydrophilic groups is easy to combine with hydrolyzed dyes. While lauryl betaine is a small molecule surfactant, the structural differences make the response surface method model show that polyvinylpyrrolidone has a better effect than lauryl betaine. The discoveries can be used to guide dye transfer inhibitor development. Further investigations, including dye transfer inhibitor synthesis and modification, are needed.

Electrospun porous beaded fibers show great potential in the industrial application of many different fields; in addition, the processing parameters play an extremely important role in producing the required porous beaded fibers. In this study, polystyrene porous beaded fibers were fabricated via the electrospinning method. To further research into the formation mechanism of the electrospun porous beaded fiber, the influences of both flow rate and applied voltage on the jet motion and surface morphology of polystyrene porous beaded fibers were investigated in a systematic and comprehensive way. Images of jet trajectories and fiber morphologies under selected parameters were captured by high-speed photography and scanning electron microscopy, respectively, to explore the formation mechanism of porous beaded fibers. The experimental results showed that both flow rate and applied voltage have tremendous influence on the jet pattern and resultant fiber morphology, namely, the higher flow rate results in a multi-jet pattern and larger bead diameter, and the larger applied voltage leads to multi-jet trajectory and a reduction in the number and diameter of beads.

In this study, we used the new nanobubbles technology to create a green reactive washing process for the textile industry, as one of the most polluting sectors where environmentally friendly process designs are indispensable to protect the environment. With this technology, the possibility of eliminating the soaping-off step from the reactive washing sequence was investigated. For the design of an environmentally friendly reactive washing process, the effects of increasing the process temperature of the soaping-off step as well as the use of oxygen-enriched NBs in all washing steps after reactive dyeing with three different dyes were investigated. The results were evaluated by comparing the color coordinates, strength, and fastness of dyed cotton towels washed according to the conventional and alternative processes as well as examining the absorbance and chemical oxygen demand values of the washing baths. Alternative washings did not cause significant differences in color coordinates, while the lowest color strength and highest fastness values were obtained after washing with nanobubbles. The absorbance graphs showed that the most colorful baths belonged to the first bath of the nanobubble washing regime. Chemical oxygen demand measurements revealed that the alternative washing systems were more environmentally friendly than the conventional ones. Based on the results of this study, we concluded that it was possible to implement more eco-friendly washing methods by eliminating the use of soap. Graphical abstract

The production of colorful yarn dyed fabrics consumes a lot of dyes, auxiliaries, and water. It generates a plethora of chemical pollutants and will cause potential environmental problems. Defining the chemical footprint can transform the environmental risk caused by human activities into an intuitive form of toxicity measurement. Based on the chemical footprint methodology, this article calculated and evaluated the chemical footprints of a kind of yarn dyed fabric with the USEtox model. The results revealed that sodium hydroxide caused the most severe human toxicity, and di(hydrogenated tallow) alkyl dimethyl ammonium chloride caused the most severe ecotoxicity. The comprehensive evaluation of human toxicity and ecotoxicity with life cycle assessment polygon method showed that the preshrinking process had the largest environmental load. Selecting environmentally friendly softeners in the preshrinking process can alleviate the environmental impacts caused by the production of yarn dyed fabrics.

Besides the advantages of polyester materials, such as ease of production, usage, and maintenance, the hydrophobic properties could cause disadvantages. Applying hydrophilic finishing to the polyester product, its liquid transmission properties could be improved, and better comfort provided to the user. This study aimed to investigate the liquid absorptivity properties (vertical wicking, water vapor permeability, and drop test) of the fabric given hydrophilic properties by applying a partial hydrophilic process on a 100% polyester textile surface. It aimed to transfer the hydrophilic finishing agent to the polyester product using a printing method other than the padding method. In the printing application, 100% open, striped (50% open – 50% closed), continued honeycomb (65% open – 35% closed), and non-continued honeycomb (35% open – 65% closed) pattern screens were used. The liquid transmission properties of fabrics were evaluated by changing the ratio of the hydrophilic treatment applied to the fabric surface via with the printing method. In terms of the applicability of the printing method as an alternative to the impregnation method in order to achieve decreased chemical consumption, it was aimed to investigate whether the method of giving hydrophilic features by the printing method could create an alternative to the padding method. The results showed that the liquid transmission properties of fabrics could be controlled and improved by the printing method depending on the proportions of the hydrophilic and hydrophobic surface areas. In addition, it was observed that the liquid transmission properties of the fabrics vary depending on whether these areas are continued or non-continued.

In addition, it was observed that the liquid transmission properties of the fabrics vary depending on whether these areas are continued or non-continued.","PeriodicalId":6955,"journal":{"name":"AATCC Journal of Research","volume":"9 1","pages":"143 - 151"},"PeriodicalIF":0.7,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45286163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of novel nanofibrous filters has received much attention. Nanofibrous nonwoven mats are applicable in air filtration, but their structural characteristics lead to weak mechanical properties. By incorporating graphene with polyimide, we fabricated nanofibrous mats for air filtration. The results indicate that these mats are highly efficient (up to 99.1%) for air filtration and have strength improvement and thermal stability. These mats are expected to be applied for extreme conditions.
