Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures
Packaging Technology and Science, EarlyView.This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...

Grafting of polypropylene fibers. II. Electrokinetic properties of grafted polypropylene fibers
Journal of Applied Polymer Science, 1987Electrokinetic 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.

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.

1999
Special types of polypropylene (PP) fibers were developed in order to widen their application. The special fibers may be ranged into the following main groups: • multicomponent fibers containing at least two different polymers; • fibers with changing cross-section geometry (profiled and partly filled); • bioactive fibers.

Fractographic characterization of isotactic polypropylene fibers
Microscopy Research and Technique, 2020AbstractIn 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 ...

The Coloration of Polypropylene Fibers
1987Polypropylene, as produced, does not possess properties normally attributed to a fiber-forming polymer. Despite a relatively low melting point, it is not stable below melt temperatures and will degrade in UV light at room temperature, unless stabilizers are added.

Effects of reinforcing fibers on the crystallization of polypropylene
Polymer Engineering & Science, 2000AbstractThe 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).

Polymorphism in polypropylene fibers
Journal of Applied Polymer Science, 2003AbstractThe 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.

Bagasse Fiber-Polypropylene Based Composites
Journal of Thermoplastic Composite Materials, 1999Processing 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.
