The paper considers the use of basalt ore - natural raw materials volcanic origin in Uzbekistan, as well wide fibers various sectors economy and their further prospects. Basalt rocks are for production ultrafine fibers, belong to magmatic possess high chemical thermal stability. single-component that have been enriched, melted homogenized by ancient activity. However, main energy input primary ...

poly(vinylidene fluoride) (pvdf) fibers with two molecular weights were prepared via electrospinning process. in this process, the concentration of spinning depended drastically on the gelation process. also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (sena). proof of this incompatibility was explained by the properties of pvdf and its...

The essence of the pneumo-mechanical spinning method lies in transformation tape into a discrete stream fibers, formation wedge-shaped ribbon from this form an open end groove chamber and yarn by torsion, which is removed wound bobbin. Yarn obtained on rotor machine differs structure ring machines, it has lower breaking load produced with higher filling twist.

Nanofiber-based products are widely used in the fields of public health, air/water filtration, energy storage, etc. The demand for nonwoven is rapidly increasing especially after COVID-19 pandemic. Electrospinning most popular technology to produce nanofiber-based from various kinds materials bench and commercial scales. While centrifugal spinning electro-centrifugal considered be other two wel...

We describe a phenomenon of ribbon-to-fiber transformation observed in the process of spinning of single wall carbon nanotubes dispersed in polymer solutions. In the process of spinning, a gel-like ribbon comprised of nanotube bundles bound by polymer is withdrawn from a solvent bath. We show that upon crossing the liquid-air interface, the ribbon may either retain its flat shape or fold into a...

Wet spinning was used to manufacture fibrous alginate hydrogel wound dressings. Samples manufactured using varied operating parameters (decreased air pressure and calcium concentration or increased nozzle diameter and alginate concentration) were compared with the control samples. The changes in the fiber size, Young's modulus, swelling ratio, fetal bovine serum (BSA) release efficacy, water va...

A facile method termed magneto-mechanical drawing is used to produce polymer composite microfibers. Compared with electrospinning and other fiber spinning methods, magneto-mechanical drawing uses magnetic force generated by a permanent magnet to draw droplets of polymer/magnetic nanoparticle suspensions, leading to fabrication of composite microfibers. In addition, because of the rotating colle...

Major ampullate (MA) spider silk has fascinating mechanical properties combining strength and elasticity. All known natural MA silks contain at least two or more different spidroins; however, it is unknown why if there any interplay in the spinning dope. Here, spidroins from Araneus diadematus are co-produced Escherichia coli to study possible dimerization effects thereof on of fibers. During p...
