棉氨汗布的尺寸及物理性能测试研究

基于氨纶的性能特点,采用19.68 tex的环锭纺棉纱和44.00 tex氨纶在28针/25.4 mm的Relanit3.2针织圆机上,编织纯棉、棉氨半添纱、棉氨全添纱3种纬平针织物,并分别编织3种线圈长度的试样,对织物的尺寸及物理性能进行测试。结果表明,线圈长度和氨纶含量对针织物的尺寸及物理性能有一定影响;随着氨纶含量的增加,织物横密、纵密增大;含氨纶的面料更紧密,织物的克质量和厚度较大,但透气性、抗起毛起球性、歪斜程度较差。     

艾草改性竹黏纤维针织物服用性能测试分析

对8种不同规格的艾草改性竹黏纤维针织物的服用性能进行测试,并分析其耐磨性、抗起毛起球性、芯吸性、透气性、透湿性与织物结构参数之间的关系。结果表明,艾草改性竹黏纤维针织物的芯吸性、透气性和透湿性较好,艾草改性竹黏纤维含量对针织物的耐磨性和抗起毛起球性影响不大。艾草改性竹黏纤维与涤纶纤维混纺可以提高织物的耐磨性,但织物的芯吸性会略微下降。织物组织结构是影响织物透气性的重要因素,采用提花、网眼和蜂窝类组织可以提高织物的透气性,但织物的耐磨性和抗起毛起球性会有所下降。

Effect of blend proportion on thermal behaviour of bamboo knitted fabrics

This study presents the thermal comfort properties of single jersey knitted fabric structures made from cotton, regenerated bamboo and cotton–bamboo blended yarns. Cotton, bamboo fibre and blends of the two fibres (100% cotton, 100% bamboo, 50:50 cotton:bamboo, 67:33 cotton:bamboo, 33:67 cotton:bamboo) were spun into yarns of identical linear density (20?tex). Each of the yarns so produced was converted to single jersey knitted fabrics with loose, medium and tight structures. The thermal conductivity of the fabrics was generally found to decrease with increase in the proportion of bamboo fibre. The relative water vapour permeability and air permeability of the fabrics were observed to increase with increase in bamboo fibre content. Statistical analysis also indicates that the results are significant for air permeability, thermal resistance, thermal conductivity and relative water vapour permeability of the fabrics.     

The effect of knit structures with tuck stitches on fabric properties and pilling resistance

The patterns of knit fabrics are designed by loops, tuck stitches, and float stitches and their combinations. The tuck stitch has important influences on fabric properties. It increases the fabric’s weight, thickness, and width and makes the fabric more porous than other fabrics. In this study, to determine the effects of knit structures which are made from the same cotton yarn with tuck stitches on fabric properties and pilling resistance, circular knit fabrics with different locations and number of tuck stitches were produced and dyed under the same conditions. In the evaluation process of the results, graphs were drawn and variance analyses were performed. At the end of the study, important findings were determined. The number and location of the tuck stitches and stitch length are effective factors on the structural, physical properties and the pilling resistance of knit fabrics. The fabrics with tuck stitches have much higher porosity, weight, and thickness compared to single jersey fabric. The dyeing process increases fabric weight. Single jersey has the lowest pilling resistance in comparison to fabrics having tuck stitches. The fabrics having more pores and larger pores show higher resistance to pilling. Dyeing and finishing processes decreased the pilling resistance of fabrics.     

Investigation into the curling behavior of single jersey weft-knitted fabrics and its prediction using neural network model

This research investigates the effect of fiber, yarn, and fabric parameters on curling phenomenon of single jersey weft-knitted fabrics which is interpreted to have curling surface in both course and wale direction. Taguchi’s experimental design is used to estimate the optimum process conditions and to examine the individual effects of all controllable factors on curling one by one. The controllable factors are blending ratio of polyester to cotton fiber, yarn twist and count, fabric structure, knit density, and relaxation time. Results show that fabric structure and knit density have the most dominant effect on the fabric curling. The optimum conditions of minimum curling values were also determined. Finally, the curling surface in course and wale direction as a two features of curling phenomenon was predicted using artificial neural network which selects scale conjugate gradient learning algorithm based on process parameters of single jersey weft-knitted fabrics. Our findings confirm the good capability of artificial neural network algorithm to predict these features.     

Instrumental evaluation of fabric abrasive wear using 3D surface images

Fabric abrasive wear consists of both fuzzing and pilling phenomena, which are often assessed subjectively by comparing the sample to the photographic standards. This paper introduces a stereovision system to generate the three-dimensional (3D) image of surface appearance for objective evaluation of fabric wear. The 3D information of a fabric surface obtained from the stereovision system can be used to extract the fuzzing and pilling parameters that are insusceptible to fabric structures, colors, and fiber contents. Ten types of fabrics were treated on a standard fabric abrasion testing machine (the Martindale Tester) and visually graded. From the 3D images of these fabrics, the fabric fuzziness was quantified using a set of surface roughness parameters, such as the root mean square roughness (R_q), the mean roughness depth (R_z), bearing ratio (t_p), and skewness (R_sk), and the fabric pilling was measured by density (D), height (H), size (S), and area ratio (AR) of individual pills. The results from the 10 tested samples demonstrated that the 3D measurements can characterize fuzzing and pilling appearance of fabric and quantify the degree of fabric abrasive wear.
