The yellowing resistance of Polyamide 6 fibres modified with acetic anhydride in both aqueous and non-aqueous media vis. dimethylformamide and dimethylsulfoxide was investigated. The modification resulted in a pronounced improvement in yell...
Studying of some factors which affecting the properties of polyethylene ropes
It was found, from a field study, that the maximum amount of ropes, which is produced in Egypt, is the polyethylene ropes. This is due to the satisfactory properties and economics of these ropes. However these ropes in general , are sufferi...
Melt-blown Lyocell – Influence of Solution Characteristics on Fibre Fineness
Melt-blowing is a technique of producing a nonwoven web of microfibres directly from polymer form to web form. Until now, this production method has been used almost exclusively with thermoplastic resins to produce webs suitable for filtrat...
Effect of chemical cross-linking on the properties of acrylic yarns
Courtelle acrylic yarns were cross-linked using hexandiol and pentaerythritol as potential cross-linking agents. Cross-linking of the yarns was achieved via the methylacrylate group present as a copolymer component in the commercially produ...
