An Overview of Genetic and Environmental Factors Affecting Wool Quality and the Usage Areas of Wool

Abstract

Although there are a wide variety of sheep breeds around the world today, the quality wool used by the textile industry comes from the Merino breed. The quality of Merino wool affects the workflow and processing efficiency of the wool in the processes that these wools will be subjected in the factory. In addition, the quality of the final products and their potential use are determined by the quality of the fiber. The factors affecting the amount and quality of wool fiber produced by a sheep can be examined under two main headings as genetic effects and physiological and environmental effects. In this review article, general information about the factors affecting the quality of the fleece and the usage areas of wool fibers is given.

Yapağı Kalitesini Etkileyen Genetik ve Çevresel Faktörler ile Yapağıların Kullanım Alanlarına Genel Bakış

Abstract

Günümüzde dünya genelinde çok çeşitli koyun ırkları bulunmakla beraber, tekstil endüstrisinin kullandığı kaliteli yün, merinos ırkından gelmektedir. Merinos yününün kalitesi, bu yünlerin fabrikada göreceği işlemlerdeki iş akışını ve yünün işleme verimliliğini etkilemektedir. Ayrıca nihai ürünlerin kalitesi ve potansiyel kullanım alanı lifin kalitesi tarafından belirlenmektedir. Bir koyunun üreteceği yapağı miktarı ve kalitesini etkileyen faktörler genetik etkiler ile fizyolojik ve çevresel etkiler olmak üzere iki ana başlık altında incelenebilir. Bu derleme makalede yapağı kalitesini etkileyen faktörler ve yün liflerinin kullanım alanları hakkında genel bilgi verilmektedir.
