Natural fibers, which are an important part of human environment, also valuable raw materials used for textile and non-textile production. Diversity natural fiber shapes forms is caused by their occurrence in different climatic zones. The abundance the sources arouses interest gives opportunity more comprehensive studies and, what follows, finding new applications fibers industry. This paper presents collection well- little-known from exotic plants that come various Image analysis conducted...
Flax and hemp fibers are known as textile raw materials with pro-health properties. This paper presents results of research aimed at investigating the antioxidant activity in order to explain a mechanism for favorable influence textiles made these when contact human skin. The study new approach evaluation terms their inherent Antioxidant properties flax were tested use FRAP DPPH methods. content phenolic acids: syringic, sinapinic, p-coumaric ferulic acid was determined HPLC. proved that...
The aim was to modify products made of natural fibres in order reduce the composite porosity, flammability and improve mechanical properties epoxy laminates. In obtain desired chemical modification roving fabric with use silanization flame retardant treatment conducted. For this purpose different types silanes compounds were used. Flammability prepared fibre - samples tested by microcalorimeter (PCFC). effect modifications reinforcing reduced even 400%. Investigations porosity composites...
This paper concerns the management of natural waste fibres. The aim this research was production multifunctional acoustic and thermal insulation materials from protein lignocellulosic fibre wastes, according to a circular bioeconomy. For manufacture materials, local mountain sheep wool mixture bast generated by string were used. Insulating in form mats produced needle-punching technique with different contents obtained. basic parameters mats, i.e., thickness, surface weight air permeability...
The aim of this research was to develop composites dedicated thermal insulation, developed on the basis natural raw materials. consisted mixture lime, cement, water, and two biodegradable materials: a local mountain sheep wool treated as troublesome waste hemp shives obtained by processing decorticated straw Białobrzeskie variety. On laboratory scale, blocks were produced with varying percentages fraction 10 30 mm. Sheep used in ways: (1) mixed mass or (2) arranged layer between lime. basic...
The commonly used flax process of decortication allows the mechanical extraction fibre from plant stems without prior retting. one-type obtained in this is characterised by very low quality, as it poorly divided, has high linear mass and amounts impurities. This paper presents a description newly developed method obtaining quality cottonized decorticated application wet degumming for fibre. experiment involved studying parameters fibres after each step technological i.e. decortication, final...
The wool of several native breeds raised in Polish mountains and foothills was examined. content natural contaminants basic parameters, thickness length determined during investigations. In addition, the morphology analyzed by electron microscopic observations. It revealed, that fleece sheep for all is a mixed type, which formed from more delicate, thinner shorter with addition thicker longer guarded hairs. fraction hairs, high amount medullated fibers kemp occur. Comparing obtained white...
The aim of the study was exploration properties wool derived from sheep reared in Poland. Twenty-nine breeds diverse type farming, e.g. for meat, dual-purpose wool-milk, and versatile are bred Poland, but only few them have uniform wool. Because there is a lack data determining quality quantity Polish wool, wool-based textile industry Poland uses mainly imported raw material. Wool has an impact on processing efficiency determines possibility its further use. In order to assess local (Polish...
The study explored the impact of hydrodynamic degumming process applied for decorticated monomorphic flax on fiber quality. experiment was designed as first stage research leading to development a method elementarization and cottonization; in particular, effectively dividing bundles ensure low linear density reducing impurities content, make fibers suitable cotton spinning systems. covered disposal gluing substances, mainly pectins from fibers, with use specially lab-scale Model Device...
The work deals characteristics of new flax Hera variety in terms fiber quality with regard to agronomic assessment and seeds quality. results the analyzes were related reference varieties Nike, Sara Modran grown Poland 2022 season. study included evaluation agrotechnical experiment, straw taking into account morphology surface as well cross section fiber. Moreover, conducted. was characterized by highest total (6.27 t/ha, 0.627 kg/m2) yield (5.16 0.516 kg/m2). Straw best average (78.5 cm)...
Introduction: Butterfly pea flower Clitoria ternatea L. belongs to family Fabaceae. The plant has many applications in various industries. most important usage is medicine and as a food dye. In Europe, it almost unknown textile dye, unlike Asian countries. Objective: aim of the study was assess dyeing properties materials made from protein fibers (sheep's wool natural silk) by water extract pea.Methods: Knitted fabric sheep's silk were selected for testing. colors both using six methods...
The aim of this study was to develop a natural nonwoven layer made cottonized bleached flax and cotton fibers which is suitable replace one the three polypropylene layers face mask type II in order reduce non-biodegradable waste production limit negative impact used masks on environment. work focused design structure based properly blending as well ensuring cover factor, can support mask's barrier properties against air dust particles does not make breathing difficult. Additionally,...
The aim of this study was to explore the possibility re-use disposable masks in order prevent excessive waste generation during pandemic period. COVID-19 has caused rapidly increasing production resulting from necessity common usage personal protective equipment. This research covers evaluation structure surgical subjected a threefold steam, gas or plasma sterilization process verify their re-use. results showed that even after three cycles did not cause significant changes mask air...
Summary Introduction: Coreopsis tinctoria Nutt. is an annual plant with small flowers in yellow and claret. In dyeing process, a whole range of colours can be obtained using various methods. Objective: The aim the study was to present wide colors little-known C. . its health promoting properties. Methods: our research, we selected 3 types wool: Polish Merino, Żelaźnieńska, Lowland Sheep compared on these wools 6 Results: results indicate that basic colour wool influences intensity after as...
