Blended Polypropylene Fibers

Journal of Macromolecular Science, Part A, 1998
The preparation, and especially the dyeability of blended fibers polypropylene and terpolymer acrylonitrile-butadiene-styrene and/or polypropylene and polystyrene, respectively are presented in this paper. Modified polypropylene fibers fix the dyestuffs much better and have lower tenacity according to the amount of the additive.

Fractographic characterization of isotactic polypropylene fibers

Microscopy Research and Technique, 2020
AbstractIn this article we present an opto‐thermo‐mechanical characterization of isotactic polypropylene monofilament during failure by fracture. The digital photoelasticity, the two‐beam Pluta polarising interference microscope and the computed tomography are used to provide quantitative data and visual models of the fracture regions of isotactic ...

Grafting of polypropylene fibers. II. Electrokinetic properties of grafted polypropylene fibers

Journal of Applied Polymer Science, 1987
Electrokinetic properties of methacrylic acid- and acrylonitrile-grafted polypropylene fibers measured in the presence of cationic dyes are reported. The zeta potential of polypropylene fibers decreases, and the surface charge density along with surface conductivity increases as the concentration of the dyes in the streaming solution increases.

Effects of reinforcing fibers on the crystallization of polypropylene

Polymer Engineering & Science, 2000
AbstractThe effects of the incorporation of different types of fibers on the crystallization kinetics and thermodynamics of isotactic polypropylene (iPP) are investigated. The study is mainly performed by thermal analysis, both in isothermal and constant cooling rate conditions, utilizing differential scanning calorimetry (DSC).

Bagasse Fiber-Polypropylene Based Composites

Journal of Thermoplastic Composite Materials, 1999
Processing and properties of bagasse fiber-polypropylene composites are reported. Four different chemical treatments of the vegetal fibers were performed in order to improve interface adhesion with the thermoplastic matrix: namely isocyanate, acrylic acid, mercerization, and washing with alkaline solution were applied.

Polymorphism in polypropylene fibers

Journal of Applied Polymer Science, 2003
AbstractThe structure of polypropylene fibers formed by different spinning conditions was studied. The investigations were carried out using wide‐angle X‐ray scattering (WAXS) and small‐angle X‐ray scattering (SAXS) methods. It was stated that in noncolored fibers the mesophase and the monoclinic α forms were formed.
