Theoretical Calculation Model of Single Rip Tearing Strength for the Nonwoven Composites

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.

Photo-Grafting Copolymerization of PP Nonwoven Fabric and Its Application for Acidic Dye Adsorption and Filtration

The monomer methacrylamido propyl trimethy ammonium chloride（ MAPTAC） was copolymerized onto the fiber surface of polypropylene（ PP） nonwoven fabric under ultroviole radiation. The weak acid red GN dye adsorption and adsorptive filtration performance of the resulted PP fabrics were investigated.The results showed that the grafting copolymerization preferred to happen in the inner layer of the fabrics. The water flux of the grafted fabrics decreases with the increase of grafting yield. The collapse of the grafted polymer chains causes the flux increase in acidic condition,or vice versa at alkaline version. The coiling of the polyelectrolyte chains upon the dye adsorption seems to violate the routine assumption of the rigid substrate, and this gets the adsorption energy constant negative. The static adsorption process follows the Lagergren＇s pseudo-second order kinetic equation. The removals of circa（ ca.） 100% of the total permeation volume3 500 mL simulated dye wastewater was reached during permeation.The dye adsorbed fabrics were regenerated by the mixed media of the cationic surfactant / ethanol /water. The grafted fabric assumes stable fabric integrity and stability during permeation,and presents excellent dye adsorption capacity,easy desorption, and repeatable utilization.     

＂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.     

Relationship between Light Scattering Intensity and Basis Weight of Non-Woven Fabrics

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.

气体扩散层集流体对Ni(OH)2纳米结构电化学性能的影响

We report the electrochemical performance of Ni(OH)₂ on a gas diffusion layer (GDL). The Ni(OH)₂ working electrode was successfully prepared via a simple method, and its electrochemical performance in 1 M NaOH electrolyte was investigated. The electrochemical results showed that the Ni(OH)₂/GDL provided the maximum specific capacitance value (418.11 F·g?1) at 1 A·g?1. Furthermore, the Ni(OH)₂ electrode delivered a high specific energy of 17.25 Wh·kg?1 at a specific power of 272.5 W·kg?1 and retained about 81% of the capacitance after 1000 cycles of galvanostatic charge–discharge (GCD) measurements. The results of scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS) revealed the occurrence of sodium deposition after long-time cycling, which caused the reduction in the specific capacitance. This study results suggest that the light-weight GDL, which can help overcome the problem of the oxide layer on metal–foam substrates, is a promising current collector to be used with Ni-based electroactive materials for energy storage applications.
