Stabilization of Polypropylene Fibres

Fibre Chemistry, 2001
An optimum method was found for incorporating a polymeric concentrate of the light and thermal stabilizer Chimassorb 944 in the amount of 0.2 %. The method allows fabricating a fibre with satisfactory physicomechanical indexes that retains more than 80% of its strength after UV irradiation for 30 days.

Strengthening of polypropylene fibre

Fibre Chemistry, 1971
It has been shown that elongation of polypropylene fibre at a temperature above the melting point of the unoriented polymer is accompanied not only by an increase in structure orientation, but also by formation of a denser structure, which ensures a high fibre strength.

Structure of photooxidized polypropylene fibres

Polymer Science U.S.S.R., 1987
Abstract Photooxidative degradation of polypropylene fibres which differ in the degree of orientation was studied. IR spectroscopy revealed that in the presence of light stabilizers the induction period of oxidation was prolonged and the accumulation of carbonyl groups in the fibre was slowed down.

Characterisation of modified polypropylene fibres

Journal of Materials Science, 2003
Due to excellent mechanical properties, high chemical stability and processability polypropylene fibres are mostly used in different technical fields. However, because of low surface energy, lack of reactive sites and sensitivity to photo or thermal oxidation the polymer properties are insufficient for some applications.

Interfaces in Alfa Fibre-Polypropylene Matrix Composites

Materials Science Forum, 2008
Model composites with Polypropylene (PP) as matrix and alfa fibres (cellulose-based fibres obtained from the esparto grass of the subsaarian dry regions of Tunisia) were prepared for fibre/matrix interfacial characterization studies. The matrices tested were PP and PP combined with PP modified with maleic anhydride (PP-g-MA).
