Biodegradable Nonwoven of an Aliphfatic-Aromatic Copolyester with an Active Cosmetic Layer

Abstract

Polymeric products enriched with natural additives e.g. hyaluronic acid, plant hydrolates or collagen may find a wide application avenue due to the ever-growing demand for natural cosmetics. The ecology of cosmetics is equally important. Therefore, in the work presented a biodegradable nonwoven was prepared with natural components as an active layer for cosmetic application. Synthesied was the biodegradable aliphatic-aromatic copolyester: poly (1.4 butylene succinate-co-glutarate-co-adipate-co-terephtalate). suitable for the forming of spunbond nonwoven. The active layer was deposited by padding on basic nonwoven. Assessed were microbiological and mechanical properties as well as the in- compost decomposition of the product. Activity against S. aureus and E. coli was tested and microbiological purity estimated. The best serviceable composition of the active layer was selected based on the microbiological properties tested. It contains sodium hialuronate, plant hydrolate of the bitter orange (Neroli), and collagen. Thanks to good mechanical properties, nonwoven made of aliphatic-aromatic co-polyester may serve as a carrier of the cosmetic layer in applications like face masks.

Comparison of the Silhouette of Virtual Clothes by Fabric Characteristics of Nylon Fabric for the Utilization of Virtual Clothes

“…Samples were prepared in three directions: warp, weft, and bias. The experiments were conducted sequentially on the weight, thickness, bending stiffness, and tensile stiffness, which are less damaging to the fabric . To measure the weight, the average weight in the warp, weft, and bias directions was measured using an electronic scale, and the weight per unit area was obtained by dividing this by the fabric area.…”

The thickness of the samples was measured using the thickness tester of the CLO kit according to the CLO fabric kit manual, and the bending distance and length were measured using a bending tester.…”

Biodegradable Nonwoven Materials with Antipathogenic Layer

“…Meltblow nonwoven, 1000× The nonwoven was activated by the padding method, which did not change the morphology of the fibers. The applied substances covered the fibers without damaging their structure [55]. The biodegradable spun-bonded nonwovens with active layers are shown in Figure 2.…”

Production of cellulosic textile materials with antimicrobial properties

“…Cotton, wool, silk, jute, and linen are the most susceptible to microbial attack. Microbial growth on synthetic fibers is slower compared to their natural counterparts because the polymeric backbone does not retain much water [7,8,9].…”
