“…The treated wools show significantly enhanced hydrophilicity, as indicated by the maximum wicking height up to 132 mm, which is 12 times higher than that of the untreated yarns with the maximum wicking height of 10.4 mm (figure 4(b)). This may be ascribed to the integrative action of the clean effect, rough surfaces and introduced hydrophilic bonds by oxygen plasma [33,34]. Moreover, 0.03 ml water drop can keep non-absorbent on untreated wools, but the water drop can be completely absorbed within 5 s by the treated wools (figure 4(c)).…”

Twisted yarn artificial muscles have attracted great interests for diverse applications, such as soft robotics, miniaturization controllers and smart textiles. A challenging issue in fabricating the twisted yarn artificial muscles is to retain the inserted twist. Different from the exiting strategies of forming double-helical structures or harnessing complex chemical technologies, we herein propose a simple combination of plasma and UV-light treatments to train natural wools into twist-stable single-helical yarn artificial muscles without external torsional tethering, which realizes easy fabrication of twisted actuators, and achieves better moisture-actuating performance (nearly 5 times higher in maximum rotation) compared to equivalent double-helical actuators. The stable morphology of woolen yarn muscles affected by the opening and closing of disulfide bonds is explained from microstructure characterization and theoretical analysis. The charming properties of single-helical yarn muscles will provide new inspiration for the development of fiber-based actuators in industrial routines, which is expected to promote the practical application of yarn muscles in smart textiles and wider fields.

“…Pigment printing is, as far as the simple application is concerned, not only the oldest but also the easiest printing technology. It provides advantages such as the convenience of practically final printing in its printing stage, print quality and adaptability to practically all types of fabric or mixture as well as the ability to avoid washing after fixing [43]. Fine spreading thicknesses that have little appeal to any fabric [43].…”

“…The process of plasma is extremely simple to handle and only requires a brief treatment period; the surface alteration depths of plasma material vary from 100 to several micrometers; the bulk of the polymer remains intact; and the original material retains mechanical, physiochemical, and electro-physical properties [43]. Plasma is a complete gaseous ion, electron, metastable, neutral, radical, and photonic combination.…”

“…This article analyzes the capacity of the pigment-printing process to print diverse textile materials (natural, synthetic, and mixes) with natural dyes (which have no affinity for some of the fibers) (which have no affinity for some of the fibers). [43] Two different techniques can be applied i) Treatment with plasma then printing and ii) Printing then plasma treatment i) Plasma treatment è printing process è fixation è washing è air-drying.…”

P LASMA treatment for almost all synthetic and cellulosic textiles is considered to be one of these physical technologies. Plasma treatment does not involve the treatment of hazardous chemicals and thus, compared to chemical treatment, there are no problems with effluents. The study demonstrated that most types of materials (natural synthetics and blends) with natural dye using pigment printing techniques can be printed using high-quality plasma radiation. It is an environmentally friendly process, fast-growing, and finds certain potential applications. The study claims that polyester plasma therapy and surface modifications can alleviate difficulties with printing. The study investigates the treatment of a PET fabric with an efficient plasma approach to activate the surface before cationization treatment.

“…Wetting is the capacity of a fluid to continue reaching with a strong surface that coming about because of the intermolecular associations. the level of wet (wettability) is controlled by a force balance among adherent and coherent powers [21]. The contact point (θ), as set in Figure 6, is the edge at which the liquid-vapor interface meets the solid-fluid interface.…”

B IORemeDIAtION using enzymes is an important tool in textile industry; therefore the goal of the present study is to subrogate the pretreatment of natural (cotton) and recovered (viscose) cellulosic fabrics with microbial acidothermophilic cellulase produced by the native egyptian fungus Aspergillus terreus RS2. the produced enzyme was examined at two activity levels (10 and 20U/mL) in order to reduce the effluent load that was produced from scouring and bleaching processes and to upgrade a naturally adequate transaction for water and power economy. the effectiveness of the enzymatic pretreatment under the optimum conditions on raw, scoured and bleached cellulosic fabrics has been proved as the results indicated an increase in the color intensity of the treated fabrics in compare to the untreated one for different classes of reactive dyes based on Anthraquinones and Double azo. the fastness properties of the pretreated dyed fabrics were implemented. the contact angle for the pretreated cellulosic fabrics, tensile strength, Scanning electron microscopy and FtIR analyses were performed.
