Since the fall of 2004, textile and apparel students at a United States public university have been designing apparel with nonwoven fabrics. Over the last two years, the students' designs have sparked interest in the industry which has begun to create new and innovative fabric designs. The industry, however, still struggles over the best name for the fabric. This sparked the research question, "What impact 15- to 25-year-old's intent to purchase a garment?"Through a convenience sampling method, an online questionnaire was distributed to 15- to 25-year-old United States females. The questionnaire included questions regarding demographics and psychographics, and asked respondents to choose garments they would intend to purchase based on known attributes such as style, brand,price, place, and fabrication and fiber content. There were a total of 14 garments, seven tops and seven bottoms. Four of these garments, two tops and two bottoms were constructed of nonwoven fabrics.The respondents accepted the nonwoven fabrics when shown in garments in an online setting. This demonstrates that visually, these fabrics are comparable to traditional woven and knit fabrics. The "nonwoven" polyester and nylon blend fabric increased in popularity when the respondents were told the fabrication and fiber content.However, the "engineered" polyester and polyethylene blend fabric dropped to last place when fabrication and fiber content were known. This indicates that 15- to 25-year-old respondents do not understand or are not interested in fibers or fabrications described as "engineered fabric" with a polyester/polyethylene blend. More research will have to be done to determine if the fabrication term "engineered fabric"or if the polyester/polyethylene blend fiber content caused a lack of interest or decreased intent to purchase.Research has currently begun to determine the right combination of fiber content and fiber size to develop a nonwoven fabric with an acceptable hand for apparel fabrics.  相似文献

The nonwoven composites have sandwich structure, with the first and third layers being nonwovens and the middle layer of woven fabric. On the basis of tests of the single rip tearing strength and drawing out resistances of both the nonwoven composites and the woven fabric, the single rip tearing failure mechanism of the composites were analyzed. Then theoretical calculation model for the single rip tearing strength was established, which indicates that the breaking strength of warp and weft yams in the nonwoven composites, the density of warp and weft yarns and drawing out resistances are the main influencing factors. In the end, experimental verification was made, which shows that theoretical values conform to the measured values well.  相似文献

本文研讨非织造布力学性质估算方法。取对称于两垂直轴的各向异性平面体,各方向的应力与应变保持线性,应用平面体任意方向的拉伸模量与主模量间的关系式,推导得出上述平面体的顶破强力计算公式。顶破强力计算式中包括舍弹性常数(材料拉伸应力方向与主模量方向间夹角的函数)、材料最小断裂伸长率和试样尺寸等参数。设令非织造布符合上述平面体模型,采用非织造布力学性质实测资料验证其适应程度。文中给出两种涤纶热轧非织造布的试验结果与理论计算值随参数值变化的规律基本一致,丙纶溶喷非织造布的顶裂强力实测值与理论计算值的差异随参数值不同而变化。  相似文献

Spacer fabric is a typical three-dimensional fabric, including upper layer, lower layer, and spacer layer. It is widely applied in protecting cushion products for unique space structure, which attributes good comfortability to infants and the disabled elderly in reducing diseases resulting from hot and humidity under long-time sitting and lying period. It necessitates studying the microenvironment change between body and clothes and corresponding performance. Compressibility. air permeability, heat and moisture permeability, and bending and humiture in microenvlronment of spacer fabric are analyzed and compared with foam cushion and nonwoven cushion. Experimental results show that corresponding performance of spacer fabric is better in protecting cushion than those of foam and nonwoven. Compared with traditional foam cushion and non-woven cushion, spacer fabric is more suitable for protecting cushion, and provides an alternative and optimal cushion material in medical products to protect infants and the disabled elderly from bedsores resulted from long-time sitting and lying.  相似文献

The relationship between light scattering intensity and basis weight of nonwoven fabrics is studied by using the theory of electromagnetic wave propagation and scatter-ing in random media.The theoretical analysis shows that the backscattering intensity of nonwoven fabric is closely related to its basis weight,and 2 series nonwoven samples manufactured by spun-bonded and thermal-bounded processing methods are tested for checking the theoretical expression.The study shows that the scattering intensity increases with increasing basis weight of nonwoven fabrics in exponential equation,and theoretical expression is consistent with the experimental data.  相似文献
