Nylon is a long-chain synthetic thermoplastic poly meric amide having recurring amide groups as an in tegral part of the main polymer chain. This polymer is capable of being formed into a filament in which the structural elements are oriented along the filament axis. The term “nylon' includes nylon-66 (polyhexamethylene
Interaction enhancement of Lyocell cellulose chains for controlled ...
Aug 1, 2023 · Lyocell is treated as a biodegradable, sustainable, and low-carbon emission cellulose fiber, but it possesses a high fibrillation tendency in the dyeing process which is generally conducted at alkaline, wet and high-temperature conditions.
Flame-retardant anti-fibrillation Lyocell fibers prepared by online ...
Dec 19, 2023 · In this paper, we used online-treatment of coagulated fibers during spinning to obtain flame-retardant and anti-fibrillation Lyocell fibers with crosslinkers and flame retardants that penetrate the fiber surface easily and react more quickly with the cellulose molecular chains.
Sustainable Cross-Linking of Man-Made Cellulosic Fibers with Poly ...
Dec 3, 2021 · Lyocell-type fibers often exhibit a high tendency to fibrillate under wet abrasion conditions, and fibrillation must be diminished for a better quality of the textile product. In this study, we propose a green route for cross-linking regenerated cellulose fibers using citric acid (CA) and 1,2,3,4-butanetetracarboxylic acid (BTCA) to prevent the ...
High Strength Cellulosic Filament Yarn replacing Polyester & Nylon Carlo Centonze, Co-founder HeiQ Plc. ITMF Annual Conference, Samarkand September 2024
High surface area nonwovens via fibrillating spunbonded …
Sep 1, 2009 · This paper deals with the production of modified ‘Islands-in-the-Sea’ filament cross-sections that enhance the fibrillation of such filaments to produce micro- and nano-fiber webs that have considerably higher surface area compared to their conventional counterparts.
Making positive use of the fibrillation of lyocell fibres in …
Jul 1, 2023 · Surface fibrillation of lyocell offers interesting application possibilities, particularly for short fibre-reinforced materials, as the higher specific fibre surface reduces the critical fibre length of lyocell, leading to improved stress transfer from the matrix to the fibre.
Fibrillar polymer–polymer composites: morphology, properties and ...
Oct 1, 2008 · Microfibrillar reinforced composites (MFCs) are comprised of an isotropic polymer matrix reinforced with an even dispersion of high aspect ratio micro or nanofibrils, made from the secondary dispersed polymer after the blend has undergone strengthening via alignment and stretching of its molecular chains through a mechanical process.
Fibers containing the copolymers gave less fibrillation than lyocell fibers, which became more noticeable at higher VA content. Addition of copolymers proved effective for the control of...
Finishing of Lyocell Woven Fabrics | Factors That Increase Fibrillation …
Micro-fibrillation (secondary fibrillation) has been evidenced by the treatment of the textile fabric in a lab apparatus which has a perforated cylinder (carried out by the specialists from...
