Roles of Molecular Parameters in the Preparation of Syndiotactic Poly(vinyl alcohol) Microfibrillar Fiber During Saponification of Poly(vinyl ester)
We reported that syndiotactic poly(vinyl alcohol) (s-PVA) fiber of well-oriented microfibrillar structure, similar to a natural cellulose fiber, was directly formed during saponifying poly(vinyl pivalate) (PVPi) or copolymers of vinyl pival...
Improvement of the Thermophysiological Comfort with Modified Polypropylene Fibers
The search and creation of new sophisticated products, with high economic added value added and original functional properties, based on existent technology, has awake a great interest, becoming decisive to increase competitiveness of the t...
Improvement of the functional performance of Polyethylene ropes: Part (I)
Since high-density polyethylene (HDPE) ropes have been used widely in many industries, their properties and effect on the performance behavior should be thoroughly studied for each application. Processing of HDPO includes mixing of raw mate...
Effect of Acylation on some properties of Polyamide 6 Fibres
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...
Effects of Laser Induced Periodic Surface Structures (LIPSSs) on Nylon Fabrics
Laser Induced Periodic Surface Structures (LIPSSs) on polymers have been widely studied in the last decade. There are two main types, namely high-fluence and low-fluence induced structures [1]. When the laser energy is below the ablation th...
