织物结构对毛衫保暖性能的影响

为研究织物结构对织物保暖性能的影响,选取了四平组织、罗纹空气层组织、1+1罗纹组织、畦编组织和半畦编组织5种常用的毛衫组织结构,采用相同的原料编织一系列弯纱深度的试样并进行线圈长度、织物厚度、透气性和保暖性能测试。结果表明： 四平组织织物最轻薄;畦编组织织物保暖性最好且透气性最佳;织物的保暖性受厚度和透气性的双重影响,对于单一线圈结构织物,在一定的弯纱深度范围内,厚度对保暖性的影响起主导作用,随着弯纱深度的增加透气性对保暖性的影响占主导作用;保暖轻薄系数与弯纱深度之间为二次多项式关系。     

针织防晒衣面料防紫外线和热湿舒适性研究

为探讨针织防晒衣面料的防紫外线和热湿舒适性能,选取市面上8种常见的针织防晒衣面料,分别对其进行防紫外线性能、耐洗涤性、接触冷暖感、吸湿性、透湿性及透气性能的测试与分析,最后采用灰色关联分析法,优选出最佳针织防晒衣面料。结果显示：5#、6#自称具有防紫外线功能的针织防晒衣面料并不是真正意义上的防紫外线产品;水洗对针织防晒衣面料的防紫外线性能影响不大;织物吸湿性和织物厚度呈负相关;当纤维原料、纱线线密度、织物组织、织物密度相近时,织物厚度越大,织物透湿性越小;织物透气性和织物结构有关,织物结构越紧密,织物透气性越差;3#双珠地网眼针织防晒衣面料的透气性和透湿性最好,其UPF值为50.00+,UVA小于5.00%,是优质的针织防晒衣面料。

Comparative study of copper ion complex bamboo pulp and cotton knitted fabrics. Part II: wearability and durability

Apart from the antibacterial performance, wearability and durability are also important factors for the textile product quality. The paper mainly discusses the wearability and durability of bamboo pulp and cotton-knitted fabrics which were treated with alkali and copper ammonia solution. Washing fastness, release properties of copper ions when washing, bursting properties, abrasion resistance, permeability, moisture penetrability, and warmth retention properties of fabrics were tested to investigate the change after copper ammonia solution treatment. The results showed that although the release quantity of bamboo pulp fabrics was higher, the washing fastness of bamboo pulp fabrics was better than that of cotton fabrics. After 90 times’ washing, the copper ion complex fabrics still had good antibacterial performance. For both cotton and bamboo pulp fabrics, properties of the bursting strength, moisture penetrability and warmth retention had been improved, whereas properties of abrasion resistance and air permeability had receded.     

Weight reduction of microfibre polyester fabric and the effect on its physical and mechanical properties

For the present work, a heat‐set microfibre polyester woven fabric was treated with five different sodium hydroxide concentrations in similar conditions. Their physical and mechanical properties were studied and discussed. Changes in eight properties due to the weight reduction, i.e. surface properties, tear strength, crimp, compression, pressure recovery, crease recovery, abrasion and weave density which are reported in this work were not available for any type of weight reduced polyester fabrics in the cited literature. Results show that the weight reduction decreases yarn and fabric strength, fabric abrasion resistance, fabric tear strength and bending stiffness. On the other hand, it increases fabric thickness under low pressure, crease recovery angle, air permeability and drape of the fabric. The treatment showed no significant effect on the surface properties of the samples.

The Assessment of Fabric Wear and Handle Caused by Increments of Accelerator Abrasion in Dry Conditions Part I: Changes in Some Fabric Mechanical Properties as a Result of Abrasion

In this paper, sane aspects of the physical and mechanical properties of woven fabrics, such as mass, thickness, stiffness, air-permeability, and compression, are considered as criteria for assessing the effects of damage caused by changes in frictional abrasion when the Accelerator Tester is used. Two 100% cotton woven fabrics were used in the experiment. Results show that changes occurred in fabric properties as a result of incremental wear. The mass per square metre, coercive couple, and flexural rigidity show a consistent decrease, while thickness, air–permeability, and compression show inconsistent increases with increasing time of abrasion.     

Characterization of fabric properties knitted from multifilament polyester textured yarns with various number of filaments

The purpose of this study is to investigate the physical and mechanical properties of fabrics knitted from textured polyester multifilament yarns with various numbers of filaments in the yarn cross-section. In this regard, some of the characteristics of yarns and fabrics, knitted from the mentioned yarns, were measured and analysed. Analysis of results showed that increasing the number of filaments in the yarn cross-section leads to a decrease in yarn’s diameter and abrasion resistance. Moreover, examining the properties of the weft-knitted fabrics revealed that increasing the number of filaments causes a rising trend in the compressibility and bursting strength of fabric. On the contrary, the thickness, air permeability and abrasion resistance decreases due to a growth in the number of filaments. A decline in the strength and elongation of yarns and fabrics produced from them is also another result of increasing the number of filaments in the yarn cross section.     

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.     

Permeability properties of single jersey fabrics made of hollow yarns

In this work effect of using hollow yarns on the permeability properties of the single jersey knitted fabrics were studied. Firstly yarns were produced by ring spinning machine using cotton, viscose and acrylic fibres in the mantle and water soluble polyvinyl alcohol (PVA) fibre in the core. Single jersey fabrics were knitted and PVA core was removed subsequently by washing process to create hollow yarn. Weight, air permeability and water transmission rate properties of fabrics were measured before and after washing and compared with reference fabrics. Due to the removal of PVA fibres from the yarn core after washing treatment, air permeability and water vapour transmission rate of the all kind of single jersey fabrics which were produced with hollow yarns increased as well as weight of the fabrics decreased which will cause more comfort during any exercise. It was also found that mantle fibre type and PVA ratio have significant effect on the fabric properties.
