Study On The Moisture Comfortable Performance About Thin Wool Knitted Fabrics

Wool is a natural textile fiber, and wearing comfortable of wool is well. For a long time, warmth and flexibility are concerned more when producing wearing knitted fabrics by wool, so wool fabrics are often used on thick clothing in autumn and winter. With the development of production on fine count of wool fiber and yarn, and in-depth study on wool clothe comfortable, people become realized that fine wool yarn is also suitable for summer clothing, even some features better than cotton fabric which is often used on summer clothing, because wool fabric has many good properties such like high moisture absorption, non-stick body, cool sense etc. However, for the summer, the human body sweat easily, there is less study focus on the properties of wool knitted fabrics under different moisture absorption situation.This paper choice two kind of wool yarn and two contrast cotton yarn, test and analyze the influence of different humidity on wool and cotton yarn, including diameter, bending rigidity, elastic recovery and tangential compression-recovery etc. Compared with cotton yarn, experimental results showed that, under different moisture absorption, the diameter of wool yarn changed little and not obvious, bending rigidity is low and the feeling of wool is more soft and comfortable, elongation at fracture is high and become growth with the increasing of humidity, elastic recovery is excellent even under wet station.The four types of yarn were knitted to plain and interlock fabrics respectively. Moisture comfort properties of wool and cotton knitted fabrics under different moisture absorption conditions were tested and analyzed, such as air & moisture permeability, quantity of surface water, bend rigidity, compression-recovery and wrinkle recoverability etc. Results showed that the wool knitted fabric is quite well in air permeability, slightly well in moisture permeability, also superior to cotton knitted fabric in bend rigidity, compression-recovery and wrinkle recoverability, but poor in quantity of surface water.The fuzzy mathematics was introduced to evaluate comprehensively the properties of wool knitted fabrics with mathematical methods, fuzzy mathematics can be drawn quantitative relationship between the internal. It is more objective and reasonable when use fuzzy mathematics to evaluate comprehensively the properties or influence of things. In this paper, comprehensive evaluation system method of the fuzzy mathematics was used to evaluate both the wool and cotton knitted fabrics'comfort performance. The factors such as air & moisture permeability, bend rrigidity, compression-recovery and wrinkle recoverability were selected to evaluate comprehensively two kinds of fabric. Evaluation results indicate that the comprehensive performance of wool knitted fabric under wet situation is better than cotton knitted fabric. In particular, fine count wool knitted fabric's performance was significant. However, the evaluation results of the two kind of knitted fabrics is different, comprehensive evaluation should be done agine for different purposes before developing a new kind of wool knitted products.
