The use of dopamine to synthesize melanin as a natural dye on fabrics has the disadvantages of complicated processing, long processing time, and high cost. This study simplifies the processing conditions of the oxidative polymerization of dopamine and develops wool fabric melanin coatings with different finishing effects by adjusting the reaction time. The results of computer color matching, ultraviolet (UV) protection properties, and color fastness indicated that the treated wool fibers were effectively dyed, and they achieved UV resistance properties comparable to those realized in other studies in a relatively short time. The degree of lightness (L) and UV protection factor of the treated fabric reached up to 13.3 and 80+, respectively. Samples W/PDA 60 and W/PDA 120 absorbed more than 95% of the UV light. The color fastness was greater than Grade 4. The Fourier infrared spectrum and X‐ray diffraction studies revealed that the chemical and crystalline structures of the wool fiber did not change significantly after the treatment. The breaking strength of samples W/PDA 60 and W/PDA 120 was about 50% higher than that of the original wool fabric. This efficient and simple method provides a feasible and promising solution for the color deepening and UV finishing of high value‐added wool products. It can be a potential choice for upgrading the printing and dyeing industries from the perspective of ecological protection.

The present study reports the mechanical performance of polytetrafluoroethylene (PTFE) coated fabrics. Glass fabrics with two weave structures, three dimensional plain-woven knitted (3D) and satin weave (SW) were tested. These fabrics were coated with PTFE in different weight percentages (30% and 60%). Mechanical tests included uniaxial tensile, tear (double tongue and pendulum tear), puncture, yarn pull-out and low-velocity impact (LVI) tests. The influence of weave pattern and PTFE coating on these mechanical properties was investigated. In the case of yarn pull-out and tensile tests, 60% PTFE coated glass fabrics exhibited better performance due to the increased adhesive bonding and inter-yarn friction. However, the 30% PTFE coated glass fabrics exhibited better performance for tear, puncture, and LVI tests. The SW fabrics exhibited superior performance to the 3D fabrics in all the mechanical tests performed. Overall, the results indicate that SW fabrics offer better mechanical performance than 3D fabrics under different loading conditions. In terms of coating percentage, 30% PTFE coated fabrics exhibited better mechanical performance than the 60% coated ones.

“…Since Hermann Staudinger won the Nobel Prize in 1920 for his important discovery in polymeric materials to the present century, countless numbers of polymeric materials have been produced using a variety of manufacturing techniques. [11][12][13] In this context and based on the statistical reports issued by the economic research centers, the indicators of the global polymeric materials market are witnessing a huge growth for the purchase and production of these materials, assuring that these indicators will reach their highest summit in the near future. 11,14 For example, not to be limited to, in the United States of America, the purchase of polymeric materials has been estimated at a whopping sum ofe530$ billion, that the rate of purchase will increase bye5% during the forecast period (2020-2030), to becomee830$ billion by 2030.…”

Research problem The demand for polymeric materials is increasing day by day, provided that they have excellent virtues to meet desired needs. The best way to obtain high-quality polymeric materials was surface treatment in multiple methods. All the methods that have been used were expensive, multi-stage, harmful to the environment, and other shortages. Therefore, we sought in our paper to invent and develop a surface metallization protocol under green and safe conditions, based on integrating two safe methods for preparing nanomaterials (electrospinning/ultrasound) in one-pot. Aim of this work The main objective of this work is to answer a question that has been neglected in other papers: how does in-situ metallization affect the crystalline behavior of the semi-crystalline phase of the PAN matrix depending on different amounts of MA NPs and their synergy for the rest of the properties (morphological and structural) is presented, in first degree. In the second degree, an explanation of the synergy mechanism between the mechanical/hydrophilic properties and the modified structural properties of metalized fibers has explained. Results Here, an unaccustomed and green methodology to metalize the polyacrylonitrile, PAN, surface is reported with the intention of fashioning of a stable fibrous structure and the best specifications. The in-situ metallization process is essentially based on a loading of various amount of silver nanoparticles, as MA NPs “MA NPs”, (1 wt%, 4 wt%, 7 wt% and 10 wt%), which prepared by ultrasound irradiation assisted with a little amount of a reducer system (hydrazine/NaOH), on the PAN surface. The physiochemical characterization of as-synthesized fibrous samples was consisted of two parts: (i) characterization of sample nature (utilizing of XRD and UV-Vis. techniques), (ii) the chemical structure/morphological characterization (utilizing FESEM, TEM and AFM techniques) with performing all relevant measurements. From crystalline and UV-Vis. assessments, the observed shift in the diffraction peaks towards lower angles and slight shifts in the absorption bands of PAN (1 0 0) in the 1AgPAN and 4AgPAN samples, containing smaller-sized nanoparticles, are overt results of an improvement in the crystalline traits of the parent matrix. The FT-IR data revealed the intensification and overlapping of the IR-bands “C= N, C≡ N, N-H, C=O and O-H” without band shifting for fibrous samples with low content of MA NPs (1AgPAN and 4AgPAN samples). The intercalation of the MA NPs between the chains of the molecular matrix and the strong interconnection/hydrogen bonds between both components explain not only the change of the crystalline properties of the crystalline matrix but also the homogeneous distribution and creation of a stable layer of the MA NPs on the 0AgPAN surface, confirmed by the FESEM and TEM images. The results of the study of mechanical properties showed that the loading of small spherical particles onto the polymeric matric, in particular 1AgPAN and 4AgPAN samples, was positively reflected on the improvement of the mechanical performances and the related values, not in the 7AgPAN and 10AgPAN samples. Because the MA NPs have a hydrophobic character, loading them onto the bare polymeric fiber surface made the metalized fibers a stronger hydrophobic than that of hydrophilic character, which is consistent with differences in surface roughness (increasing Ra values). The main focus of this paper was to study the synergy of structural properties with each other. So, the results of the synergistic relationship study showed that the low amount of the MA NPs led to a comprehensive and positive correlation between all structural properties and in turn affected the mechanical properties-hydrophobic/hydrophilic properties. Noting that the fibers of the 1AgPAN and 4AgPAN samples had the best structural stability, compared to the fibers of the 0AgPAN, 7AgPAN and 10AgPAN samples, when they were: decreasing in Z value, increasing fiber diameter/particle size “P.S.”, increasing RCR and C.D. values and decreasing D.D, alteration in values obtained of the mechanical behavior and the increasing of contact angle “CA” values for water “H2O” droplets and decreasing for ethylene glycol “EG”. As a final result, the changes observed in the aforementioned measurements were reasonably regular and gradual for fibers with low MA NPs content, while the same measurements were significantly deteriorated in the case of fibers with higher MA NPs contents.
