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...
This study presents the quantity and quality of flax (Linum usitatissimum L.) hemp (Cannabis sativa fibers obtained depending on fiber extraction method. The methods used in this were osmotic degumming, dew retting, water retting. degummed straw was analyzed for content, while metrological, chemical, physical properties determined obtained. It shown that these change based method used. highest content using degumming These are characterized by a light color, no unpleasant odor, low linear...
The article presents the exploration of flax and hemp fibers' surface free energy depending on chemical composition fiber, which is closely related to plant variety method extracting fiber. For this purpose, tests (SFE), evaluation percentage content individual fiber components FTIR analyses were conducted. research was carried out with use fibrous materials prepared in three different ways: 1. To analyze effect subsequent stages fibers refining process SFE, 2. explore dependence SFE...
Hemp fiber variety, Bialobrzeskie, contains phenolic acids in its chemical composition giving it inherent antioxidant and antibacterial activity. The use of this raw material fabric manufacture allows the creation functional clothing with a positive effect on human skin. aim study was to develop biologically active made pure industrial hemp materials, where cannabidiol (CBD) extract applied surface strengthened bioactivity. design technology focused keeping properties steady level avoiding...
Global warming has led to a change in climatic conditions. Since 2006, drought contributed reduction of food production and other agriculture-based products many countries. The accumulation greenhouse gases the atmosphere caused some changes composition fruits vegetables, making them less nutritious. To analyse this situation, study was conducted on effect quality fibres provided by main fibre crops Europe, namely flax (Linum usitatissimum). experiment consisted growing under controlled...
Abstract The presence of inhibitors proteinases was stated in many species plants. There are macropeptides the molecular weight ranging from 3700 to 8000, often bound carbohydrates. Potential sources legumes, cereals, potatoes and also some fruits. They characterized by different activity. „Single‐headed”︁ inhibit one type proteolytic enzyme, when „double‐headed”︁ inhibitors, possessing two independent active sites, can several types enzymes at same time. differ resistance temperature change...
The objectives of the study were to develop functional natural fiber clothing with microcapsules containing active herbal extracts properties enhancing treatment dermatoses and confirm efficiency clothing's activity by testing its effect on biophysical parameters human skin. As a result work, enriched green tea Viola tricolor enclosed in ethyl cellulose was produced. applied inner surface linen knitted fabric, which ensured direct contact substances patients' affected tested according our...
Abstract In this paper, we present a new methodology of clothing engineering construction for the medical application. Project “BIOAKOD” intends to propose solutions elderly people with dermatological defects. This purpose requires particular concept because additional functionality expected in clothing. It means that proposed needs cover human body an aesthetic way and gives comfort use it, it should also bring adding value health treatment dermatosis (psoriasis)..
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)...
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...
Introduction. The Institute of Natural Fibers and Medicinal Plants has been carrying out complex research connected with application natural dyes on knitted fabrics fabrics. paper presents the results part conducted at Institute, related to Project BIOAKOD – Bioactive curing clothing based fibers. Aim. aim project’s task 3 was develop organic cotton linen dyeing technology using extracts obtained from plants. Material methods. Plant depending content active substances their precious...
Abstract Relationship between genotypes represented by two fibrous hemp varieties and some agrotechnical factors was investigated in the study. The aim of it finding how selected (three sowing dates, densities five harvest dates) influence on total fiber content using osmotic degumming plants method for determination. Results showed 34% higher Beniko comparison to Tygra. It also shown that stronger correlated with date than its density.
