“…The average resistivity test values are shown in table 11. From the analysis of the experimental values we find that the values are ranged between 10 13 (Ω) to 10 14 (Ω), both for surface resistivity and for the resistivity of the volume, values above the resistivity values of dielectric insulating materials (10 11 Ω), comparable to the prexiglas, teflon, air etc. [12].…”

“…Wool has a huge potential for the use of technical textiles [5,6], thanks to its essential and unique characteristics such as: thermal resistance of high values, even in humidity conditions; capacity to minimize thermal and heat variation in humidity conditions; moisture management capacity; capacity to minimize condensation (does not favor mold growth), absorption capacity of volatile organic compounds, formaldehyde, sulfur dioxides, nitrogen oxides and carbon dioxide in the atmosphere; hypoallergenic and nontoxic character [7]; airborne and surface noise reduction capacity (reduction factor ≥ 90%), heat transfer capacity, self-extinguishing capacity in contact with fire sources, biodegradable and compostable character [8,9,10]. The paper proposes the presentation of experimental results of non-conventional textile structures (NTS) from 100% wool fibers, designed and developed at S.C. Cora Trading & Service SRL, on their existing adapted technology, with potential for use in the field of construction, thanks to the thermal insulation properties [11,12,13,14]. The particularity of these structures is the presence in the fibrous blend of both tanned wool fibers and sheared thick wool fibers, with a low degree of valorization, currently, in Romania.…”

Structuri textile neconvenționale cu destinație tehnică, proiectate și dezvoltate la S.C. Cora Trading & Service S.R.L. Fibrele de lână sunt o resursă naturală, regenerabilă, durabilă, cu un impact redus asupra mediului și un potențial enorm pentru omenire. În conditiile în care populația Terrei se înmulțește exponențial, materiile prime sunt din ce în ce mai puține, o afacere bazată pe prelucrarea materiilor prime regenerabile, în special a fibrelor de lână, are mari șanse de supraviețuire și dezvoltare. România, cu o economie agrară foarte dezvoltată, are o populație de aproape 10 milioane de ovine și o producție de peste 16.000 tone de lână medie și grosieră. Având în vedere necesitatea de a stabili cerințe minime de performanță energetică pentru clădirile noi și pentru renovarea majoră a celor existente la nivelul Uniunii Europene, este necesară dezvoltarea de noi materiale și tehnologii, astfel încât posibilitatea de a valorifica lâna pentru domeniul construcțiilor să poată fi un element funcțional pe termen lung. Această lucrare prezintă rezultatele experimentale ale caracteristicilor a 4 structuri textile neconvenționale (STN) realizate din fibre de lână 100%, proiectate și dezvoltate la S.C. Cora Trading & Service SRL, pe tehnologia proprie, existentă și adaptată. Amestecul fibros utilizat, care constă atât din lână de tăbăcărie, cât și din lână de tunsoare, permite dezvoltarea unor structuri inovatoare, cu potențial de utilizare pentru capacitatea lor de izolare termică și cu un mare potențial de dezvoltare durabilă pentru producător. Cuvinte-cheie: lână grosieră de tunsoare, lână de tăbăcărie, structuri textile neconvenționale, conductivitate termică Non-conventional textile structures with technical destination, designed and developed at S.C. Cora Trading & Service S.R.L. Wool fibers are a natural, renewable, sustainable, low impact on the environment, with huge potential for humanity. Given the exponential growth of the Earth's population, raw materials are getting less and less, a business based on the processing of renewable raw materials, especially wool fibers, has a high chance of survival and development. Romania, with an overwhelming agrarian economy, has a population of nearly 10 million sheep and a production of over 16,000 tons of medium and coarse wool. Given the need to set minimum energy performance requirements for new buildings and for the major renovation of existing ones at European Union level, the development of new materials and technologies is necessary, so that the opportunity to capitalize on wool for buildings be a workable item on long term. This paper presents the experimental results of the characteristics of 4 non-conventional textile structures (UTS) made of 100% wool fibers, designed and developed at S.C. Cora Trading & Service SRL, on their existing adapted technology. The fibrous blend used, consisting of both tanning wool and coarse shared wool allow development of innovative structures, with potential of use for their thermal insulation capacity and great potential of...

“…For the fabrication of wool-based building materials, coarse fibers or those fibers that cannot be used in the textile industry are generally used [22]. Wool has good thermal characteristics, with the thermal conductivity of wool panels varying between 0.040 and 0.041 W/mK for densities of 25 ÷ 92.5 kg/m 3 [23].…”

Innovative Use of Sheep Wool for Obtaining Materials with Improved Sound-Absorbing Properties

et al. 2020

In recent years, natural materials are becoming a valid alternative to traditional sound absorbers due to reduced production costs and environmental protection. This study explores alternative usage of sheep wool as a construction material with improved sound absorbing properties beyond its traditional application as a sound absorber in textile industry or using of waste wool in the textile industry as a raw material. The aim of this study was to obtain materials with improved sound-absorbing properties using sheep wool as a raw material. Seven materials were obtained by hot pressing (60 ÷ 80 °C and 0.05 ÷ 6 MPa) of wool fibers and one by cold pressing. Results showed that by simply hot pressing the wool, a different product was obtained, which could be processed and easily manipulated. The obtained materials had very good sound absorption properties, with acoustic absorption coefficient values of over 0.7 for the frequency range of 800 ÷ 3150 Hz. The results prove that sheep wool has a comparable sound absorption performance to mineral wool or recycled polyurethane foam.

“…The use of renewable materials for building insulation has been characterized by a significant increase in recent years, as a result of specific incentive systems and a generally increased awareness of economic and ecology related advantages [1]. Among the variety of newly proposed solutions for building wall insulation, the case of wool panels obtained by different technological processes from locally produced sheep wool is significant [2]. Despite the clear advantages associated with the use of such materials, their biodegradability can make them more susceptible to adverse environmental factors, among which a main role is played by infestations of the common clothes moth Tineola bisselliella (Hummel) (Lepidoptera: Tineidae).…”

In this study the resistance opposed to Tineola bisselliella larvae by a commercial sheep-wool panel incorporating borate salts was determined under laboratory conditions. The susceptibility of clothes moth larvae to different concentrations of disodium octaborate tetrahydrate (DOT) incorporated in pure wool was also determined. The commercial wool panel showed a remarkable resistance to moth attack compared with pure untreated wool, and the damage to panel samples was limited to their surface. As a result of bioassays exposing larvae to pure wool treated with DOT, a concentration dependent effect was observed, achieving a good efficacy at an application rate between 40–100 mg/mL. This study highlights the need to protect wool-based construction material with appropriate insecticidal (antifeedant or repellent) substances and supports the development of eco-sustainable solutions.
