INFLUENCE OF PROCESSING PARAMETERS AND POWDER BINDER CONTENT ON PROPERTIES OF HIGH LOFT NONWOVEN FABRICS

In this paper, the influence of processing parameters and powder binder content was studied and analysed on the properties of high loft nonwoven fabrics mainly using statistical analysis method. The relationship between the bulkiness and the warmth retention property was also tested. The analytical results reveal that the increase of the powder content, heating temperature and pressure will affect the tensile strength of nonwovens. Moreover, there are interactions between these parameters. The compression properties only change a little for a powder binder content of 15％—20％. However, with the increase of the heating temperature and pressure, the bulkiness and compression rate will reduce significantly. For the bulk density of high loft nonwoven fabrics, there exists a heat transter mechanism of air convection, but the higher the bulkiness of nonwovens, the larger the thickness and the better the warmth retention property of nonwoven fabrics.

＂Nonwoven＂ Versus ＂Engineered Fabric＂： the Impact These Terms Have on the 15- to 25-Year-Old Females＇ Intent to Purchase

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.

铜箔轧制滑移系演化的晶体塑性有限元模拟

为了定量描述厚度尺寸对极薄带轧制微观变形不均匀性的影响,采用率相关晶体塑性理论和Voronoi图的多晶模型,考虑试样尺寸,晶体取向及其分布,模拟了不同厚度铜箔在相同压下率条件下的变形行为,得到了在细观尺度上铜箔的微观应力应变和滑移系分布.模拟获得的应力-应变曲线和实验测得的曲线基本一致.通过对20%压下率不同厚度铜箔的轧制变形的研究表明,无论是在晶粒内部还是在晶粒间,材料变形都非常不均匀,主要是由在铜箔厚度方向上只有一层晶粒时,晶粒尺寸、形貌和取向的不均匀分布,近邻晶粒取向差以及滑移系启动特性所引起的.     

Wearability of Copper Ion Complex Bamboo Pulp Knitted Fabrics with Chitosan Pretreatment

Wearability is one of important factors for the textile product quality. The wearability of bamboo pulp knitted fabrics was mainly discussed which were treated with chitosan and cupper ammonia solution. Tensile and bursting properties, abrasion resistance,drapability,air permeability,moisture-penetrability and warmth retention properties of fabrics were tested to investigate the changes. The results showed that chitosan pretreatment improved the tensile and bursting strengths,abrasion resistance and moisture penetrability,but decreased the drapability and air permeability.Copper ammonia solution treatments decreased the tensile and bursting strengths,abrasion resistance and air permeability,but increased the drapability, moisture penetrability and warmth retention properties.

Finishing Effect on Warmth Property of Cotton/Kapok Blended Knitted Fabric

Nowadays,more and more natural or functional fibers are being investigated due to their utilization in thermal underwear.Kapok fiber is one of the natural cellulosic fibers whose source is the kapok plant. It has hollow body and sealed tail,which exhibits desirable features required for functional textiles of this nature. In this study,cotton / kapok( 80 /20 by mass) blended yarn with two types of yarn size 18. 5 and 14. 8 tex,respectively are knitted into plain stitches. The fabrics are undergone with an optimal preparation plan according to orthogonal design. Then,after dyeing and softening,fabric properties including thermal and water-vapour resistances, wicking property, pilling behaviour, and surface morphology,are tested and scrutinized for their candidacy for thermal underwear. The results showed that cotton / kapok blended fabrics have good thermal resistance which is significantly higher than those of cotton / modal blended fabrics,and the same water vapour resistance compared with cotton / modal blended fabrics which are normally used as underwear. Cotton / modal blended knitted fabrics has better pilling grade than cotton / kapok blended fabrics. Meanwhile, the cotton / kapok blends fabrics have good wicking property. Collectively,it was concluded that cotton / kapok blended fabric was appropriate for thermal underwear. However,the main limitation of these fabrics is their pilling properties.
