织物结构对吸湿快干面料导湿性能的影响

 为开发符合市场需求的吸湿快干涤纶织物,以国产吸湿快干低弹网络涤丝为原料,试制了具有不同密度和不同组织结构的系列织物,并采用毛细效应和水滴扩散试验测试其吸湿导湿性能,探讨了影响织物吸湿导湿性能的因素。分析表明织物的吸湿导湿性与织物组织结构、密度及经纬纱交织频率等有着密切的关系。纬密过高或过低、交织频率较大的平纹组织与交织频率较小的16枚缎纹组织均不利于导湿性能的提高。当经纬密度分别为64、40根/cm、组织为5枚缎纹或4枚斜纹时,织物的吸湿导湿性能较优。

干爽涤纶织物透气透湿性能测试与分析

通过对26种干爽(导湿快干)涤纶织物透气性、透湿性能的测试分析,可以看出:影响织物透气性的主要因素是纱线的组成和织物的紧度。纯涤纶织物,不论其截面形状如何,透气性都差,涤、棉交织物中,涤纶含量越高,透气性越差;纱线越粗,织物的经纬向密度越大,织物的紧度越大,透气性越差;织物的透湿性能与组成纱线纤维的种类,纱线的粗细及经纬纱的密度有关。棉的含量越高,透湿性越好,五叶涤纶丝Coolfibre(CF)与棉交织的织物的透湿能力要优于涤纶DTY与棉交织的织物。

Investigation on permeability and moisture management properties of different denim fabrics after repeated laundering

The physiological comfort determined by air permeability and moisture management properties of fabrics is influenced by various constructional parameters of the fabric which give woven fabric a porous structure. Evaporation of sweat during wear has the potential to cool the body besides restricting the additional weight of sweat being absorbed by the fabric. In this study, comfort characteristics of denim fabrics with different weft yarn of cotton, polyester and core spun Lycra have been discussed. Effect of enzyme washing and repeated laundering on air permeability, moisture management and drying rate has also been discussed. It was observed that air permeability and water vapour permeability of unwashed denim fabrics with cotton weft yarn are significantly higher than the fabric with polyester and Lycra cotton weft yarns. The wetting time is higher for cotton and Lycra cotton yarn fabrics. One-way transport index is highest for Lycra cotton weft fabrics and lowest for fabrics with polyester weft. Fabrics with polyester weft yarns show highest spreading rate, spreading radius and drying rate due to better wicking and hydrophobic nature of polyester fibres.

Thermo-physiological comfort properties of double-face knitted fabrics made from different types of polyester yarns and cotton yarn

Double-face knitted fabrics with hydrophobic inner and hydrophilic outer layers are characterised by their advantageous thermo-physiological comfort property that facilitates the transport of sweat from skin to outer fabric layer where it can be evaporated easily. In this study, for the production of double-face knitted fabrics, cotton yarn as hydrophilic yarn type and five different polyester filament yarns consisting of standard polyester, hollow polyester, micro polyester, textured polyester and textured micro polyester as hydrophobic yarn type were used. In order to determine the thermo-physiological comfort properties of the fabrics, air permeability, water vapour permeability, thermal conductivity, thermal resistance and overall moisture management capacity were measured. The results were comparatively analysed using statistical methods. The experimental results demonstrated that the polyester-type yarns and the combinations of them with the cotton yarn in fabric layers affected the thermo-physiological comfort properties significantly. The fabrics with polyester-type inner face and cotton outer face showed the best moisture transmission properties.

Thermal and mass transport properties of polyester–cotton plated fabrics in relation to back layer fibre profiles and face layer yarn types

Clothing plays an important role in maintaining thermal equilibrium between a human body and the ambient environment by serving as a medium for heat, moisture vapour and liquid moisture transfer. The ability of fabric to maintain this equilibrium is related to thermo-physiological comfort. Plating is an innovative knitted fabric production technique to obtain bi-layered fabrics. An attempt has been made to engineer plated knit structures with such a combination of fibre cross section in the back (inner/next to skin) and the yarn type in the face (outer) layer, so that a rapid liquid transfer from back layer by wicking and quick liquid absorption and evaporation by the face layer can be achieved. Plated fabrics using the combination of triangular polyester fibre in the back and carded cotton yarn in the face layer showed the higher thermal resistance, higher absorbent capacity and would be warmer to the initial touch. However, the combination of combed cotton yarn with triangular polyester fibre resulted in fabrics with the higher air permeability, moisture vapour transmission rate and transplanar wicking.
