“…Lactic acid is released during the fermentation of waste vegetable raw materials: beets, corn, cereals. At the next stage, polylactide is obtained from lactic acid by polymerization [ 3 , 4 , 5 ]. Crystalline PLA has properties similar to those of known polymers, such as polypropylene and polyethylene, but they have advantages: biocompatibility and biodegradability [ 6 , 7 , 8 , 9 ].…”

A nonwoven fiber made of polylactide/natural rubber with a rubber content from 0 to 15 wt.% was obtained by electrospinning from a solution. The water sorption test showed that the addition of natural rubber into the polylactide matrix did not significantly affect the degree of water absorption of the fibers, which was in the range of 48.9–50.6%. The melt flow rate only increased by 0.5 g/10 min at a content of 15 wt.% natural rubber. The thermal characteristics after 120 days of degradation in distilled water and UV irradiation (50 h) at a wavelength of 365 nm were determined using differential scanning calorimetry. Changes in the values of the phase transition temperatures and the degree of crystallinity were determined. It was determined that the fiber samples from all compositions retained the propensity for photo- and hydrolytic degradation.

“…Most fully biodegradable biocomposites are developed from synthetic biodegradable polymers: polylactide acid (PLA) , polycaprolactone (PCL), polyhydroxybutyrate (PHB) , and polyhydroxyvalerate (PHV). Polyolefins such as polyethylene and polypropylene are widely used for partially biodegradable biocomposites.…”

The properties of biocomposites based on ethylene–octene copolymers (EOCs) were studied. The mechanical, rheological, and physical properties of the biocomposites were investigated with attention to the filler type, filler content, and grade of EOC. Three grades of EOC with different viscosities were used as the polymer matrices. Two lignocellulosic raw materials were selected as fillers: birch wood flour (WF) and oil flax straw (FS). The effect of the filler variation range (30%–70%) on the biocomposites was studied. According to microphotographs, the filler particles were quite uniformly distributed in the polymer matrix. The WF particles had ellipsoid shapes, whereas the FS particles were characterized by cylindrical shapes. The addition of fillers decreased the elongations at the copolymer's break and tensile strengths, but increased the elasticity moduli. The fillers’ hard particles increased the stiffness of the polymer chains in the biocomposites, resulting in declines in elongation at break. The biocomposites with WF had higher tensile strengths and elongations at break than those with FS because the latter were characterized by lower density values than the former. Melt viscosity analysis showed that filler content increased with melt viscosity. The FS biocomposites had higher melt viscosities than the WF biocomposites. POLYM. ENG.

Impact of environmental agents on non-woven polylactide/natural rubber agrofiber

View full text Add to dashboard Cite

In the work an eco-friendly non-woven fiber made of polylactide and natural rubber with a rubber content from 0 to 15 wt.% was obtained by electrospinning. The influence of distilled water and UV irradiation on the agrofibers has been investigated. The water sorption test showed that the addition of natural rubber into the polylactide matrix does not significantly affect the degree of water absorption of the fibrous materials, which is in the range of 49-50.6%. Thermal characteristics after 180 days of degradation in distilled water at 22±2 oC and UV irradiation at a wavelength of 365 nm during 100 hours were determined using the differential scanning calorimetry. Changes in the values for glass transition and melting temperatures, and the degree of crystallinity were determined.
