This literature review takes on the common perception that sheep wool fibers with a fiber diameter greater than 22 to 25 μm cause a prickling sensation on the human skin. Therefore, the breeding goal was to reduce the fiber diameter with currently fibers smaller than 18 μm are being called superfine wool fibers. On the contrary, most regional sheep have a greater fiber diameter because there are mainly held for food supply and landscaping purpose. Since their wool is not further processed it is treated as hazardous waste and needs to be disposed at the owner’s cost. One obvious solution for using the existing fiber resource would be to reduce the fiber diameter. But not every breed of sheep and climatic conditions are suitable to reduce fiber diameters low enough to avoid a prickling sensation. However, there are studies on merino wool fibers indicating that there are more key determinants than just the fiber diameter who have an influence on the tactile perception such as fiber structure, curvature, bending properties, yarn and fabric characteristics. Understanding the behavior of regional wool fibers properties under the influence of a changing temperature as well as humidity and the functioning and perception of the human skin under those conditions is a crucial part in order to extend the common assumption that a prickling sensation depends solely on the fiber diameter. A distinct cause-effect relation between regional wool fibers, its products and the tactile perception of the human skin as it has been carried out for fine merino wool is key to assess the useability and evaluate areas of application. Not only applications but also the different manufacturing processes from raw wool to a finished fabric are subject to necessary adjustments in order to change the tactile perception of wool fibers other than the superfine ones. By pointing out possible applications for regional wool fibers the degree of usage of unexploited resources can be increased. A greater usage and acceptance of regional wool fibers can support and help to establish a textile value chain and sustain the genetic pool of the different breeds of sheep which can be found throughout Europe.

摘要

This literature review takes on the common perception that sheep wool fibers with a fiber diameter greater than 22 to 25 μm cause a prickling sensation on the human skin. Therefore, the breeding goal was to reduce the fiber diameter with currently fibers smaller than 18 μm are being called superfine wool fibers. On the contrary, most regional sheep have a greater fiber diameter because there are mainly held for food supply and landscaping purpose. Since their wool is not further processed it is treated as hazardous waste and needs to be disposed at the owner’s cost. One obvious solution for using the existing fiber resource would be to reduce the fiber diameter. But not every breed of sheep and climatic conditions are suitable to reduce fiber diameters low enough to avoid a prickling sensation. However, there are studies on merino wool fibers indicating that there are more key determinants than just the fiber diameter who have an influence on the tactile perception such as fiber structure, curvature, bending properties, yarn and fabric characteristics. Understanding the behavior of regional wool fibers properties under the influence of a changing temperature as well as humidity and the functioning and perception of the human skin under those conditions is a crucial part in order to extend the common assumption that a prickling sensation depends solely on the fiber diameter. A distinct cause-effect relation between regional wool fibers, its products and the tactile perception of the human skin as it has been carried out for fine merino wool is key to assess the useability and evaluate areas of application.
