The Influence of the Spinning Systems on the Surface Damage of Cotton Fibers

Damage to the surface layer of cotton fibers was observed. Cotton fibers were transformed to yarns in the classical and open-end spinning systems. Damage was observed using a scanning electron microscope JSM-5500LV f-my Jeol. The samples were chosen from the initial and final stages of the technological process. Seven types of damage to t..

Worsted Cashmere Top and Yarns Blended with Low or High Curvature Superfine Merino Wool

In this replicated experiment, we investigated the impact of cashmere on blends with superfine wools on the quality of tops, rovings, and worsted spun yarns. We also investigated the relative performance of soft, low crimp/low fiber curvature superfine wool when compared with cashmere and also when compared with traditional high crimp/hig..

다이와보노이㈜는 친환경(ECO) 관련 소재 전략 ECOFRIEND® 일환으로 면에 근접한 레이온섬유를 사용한 신소재 COLRFA를 판매 전개하고 있다.

Use of Electrospun Nanofiber Web for Protective Textile Materials as Barriers to Liquid Penetration

To examine the potential of electrospun nanofibrous webs as barriers to liquid penetration in protective clothing systems for agricultural workers, layered fabric systems with electrospun polyurethane fiber web layered on spunbonded nonwoven were developed. Barrier performance was evaluated for the layered fabric systems with different le..

Effect of Roller Speed and Moisture Content of Cotton on Ginning Rate, Lint Quality and Electric Energy Consumption in Double Roller Gins

To optimize the ginning parameters, a study was performed to investigate the influence of leather roller speed, fiber moisture on ginning rate, lint quality and electric energy consumption during ginning on double roller ginning machine. Seed cottons of different staple lengths were ginned at three levels of roller speed and moisture cont..

Kynurenine Located within Keratin Proteins Isolated from Photoyellowed Wool Fabric

This paper describes the identification of the yellow chromophore-containing residue kynurenine within photoyellowed wool. Photoyellowed Merino wool fabric was tryptically digested and the resultant peptides were separated by high-performance liquid chromatography. Peaks with absorbance at 400 nm were collected and analyzed by tandem quad..

Shear Flow Properties and Melt Spinning of Thermoplastic Polyvinyl Alcohol Melts

Polyvinyl alcohol (PVA) is a water-soluble polymer, which is difficult to process in melt form owing to its poor processability and thermoplasticity. The thermoplastic polyvinyl alcohol (TPVA) prepared in this study is a brand new material for use in melt spinning. Satisfactory processability of TPVA can be obtained efficiently by using t..

Performance of Selected Clothing Systems under Subzero Conditions: Determination of Performance by a Human-Clothing-Environment Simulator

It is necessary to measure the performance of outdoor/protective clothing materials in terms of comfort properties under dynamic enduse conditions. A vertical type human-clothing- environment simulator was used to evaluate the thermal comfort performance of layered textile materials under dynamic conditions. Fabric layers of PET knit/flee..

Simulation of Fiber Entanglement by Modeling Vorticity in Water Flow Field

This research developed a model of the hydroentanglement process, based on the first principles of fluid mechanics. This model proceeded from the assumption that fiber entanglement in the hydroentanglement process is proportional to the average vorticity in the fiberweb. Two-dimensional simulations of the water flow through the fiberweb a..
