Raw Sheep Wool Management for Thermal Insulation Materials: The Case of Lithuania

ABSTRACT

Raw sheep wool preparation processes are closely related to the use of environmentally harmful raw materials. To solve this problem, alternative ways of cleaning wool, often called environmentally friendly, are being sought. In this research, the possibilities of using Lithuanian wool for the production of thermal insulation materials were investigated. For this purpose, 4 tons of raw wool of different breeds of sheep was selected from various Lithuanian sheep breeders’ farms. Sources of impurities in wool were identified and the amount of fat in wool was assessed. After the initial re-selection, the wool was washed in different modes and with different detergents. The recycled and washed wool was supplied to the factory for the production of thermal insulation material.The aim of this work is to identify the main sources of wool impurities, analyze the quality of wool of different sheep breeds from different farms and evaluate the washing efficiency of different detergents and methods for different sheep breeds wool, and evaluate the quality of prepared wool raw material during different actual production processes. The results of the research provide preconditions for the improvement of thermal insulation materials of the sheep wool production and its quality management.

摘要

羊毛原料的制备过程与使用对环境有害的原料密切相关. 为了解决这个问题, 人们正在寻找清洁羊毛的替代方法, 通常被称为环境友好型. 在这项研究中, 研究了使用立陶宛羊毛生产隔热材料的可能性. 为此, 从立陶宛各绵羊养殖场挑选了4吨不同品种的绵羊原毛. 确定了羊毛中杂质的来源, 并评估了羊毛中的脂肪含量. 在最初的重新选择之后, 羊毛以不同的方式和不同的洗涤剂洗涤. 回收和洗涤的羊毛被供应给工厂用于生产隔热材料. 这项工作的目的是确定羊毛杂质的主要来源, 分析来自不同农场的不同绵羊品种的羊毛质量, 评估不同洗涤剂和方法对不同绵羊品种羊毛的洗涤效率, 并评估在不同实际生产过程中制备的羊毛原材料的质量. 研究结果为羊绒生产中保温材料的改进和质量管理提供了前提条件.

Highlights

The sources of impurities in raw wool are related to all stages of the raw material preparation.

The washing of raw wool can be conducted with a lower impact on the environment.

Production rate of the thermal insulation material depend on three main factors.
