Effect of Low-Molecular-Mass Additives on Structure and Properties of Nonwoven Materials Prepared by Electrospinning of Polypropylene Melts
Nonwoven materials based on polypropylene with up to 2 wt% added sodium nitrate, which allowed the fiber diameter to be reduced by 40%, were studied. The composition and structure of the materials were charact...

Electrospinning of Nonwoven Fabrics from Polypropylene Melt with Additions of Stearates of Divalent Metals
It was shown that by adding up to 10 wt. % of the stearates of mono- and divalent metals sodium, magnesium, calcium, or zinc it is possible to obtain fibers with diameters of 1-5 μm from a polypropylene melt, ...

Electrospinning of Non-Woven Materials from the Melt of Polyamide-6 with Added Magnesium, Calcium, and Zinc Stearates
Polyamide-6 fibres of diameter 2-3 μm could be produced from the melt by adding (2-10 mass%) divalent metal (Mg, Ca, Zn) stearates, which caused the viscosity to decrease and the electrical conductivity of the...

Rheological Features of Fiber Spinning from Polyacrylonitrile Solutions in an Electric Field. Structure and Properties
Spatially ordered fibers of diameter 260-990 nm were produced by electrospinning from polyacrylonitrile (PAN) solutions. The influence of the rheological properties of solutions of PAN and its copolymers was i...

Method of manufacturing nonwovens by electrospinning from polymer melts
A unit for electrospinning of polymer melts was created. Nonwovens with an average fibre diameter of 0.5-20 μm were obtained from a melt of both pure polyamide 6 and its blends with stearic acid and oleic acid...

Effect of orientation stretch on structure of a composite fibre based on high-density polyethylene and polybutylene terephthalate
Due to the effect of the HDPE matrix in composite fibres based on HDPE-PBTP it is possible to draw the polybutylene terephthalate component to degrees of orientation which exceed the degree of orientation atta...
