Abstract
(EN)
The present invention relates to a PLA composite fiber filament, as well as a preparation technique and application thereof. A PLA composite fiber filament of the present invention has a sheath-core structure, and comprises an inner core layer and an outer sheath layer wrapped outside of the inner core layer, the inner core layer being a continuous filament, the material of which the filament is made being a degradable material, the material composition of the outer sheath layer primarily being PLA, PLA indicating polymerized lactic acid, and there being an air flow channel between the inner core layer and the outer sheath layer. The beneficial effects of this are: the PLA composite fiber filament of the present invention not only has good flexibility, does not break easily and does not debond easily, but can also completely biodegrade, which helps protect the environment. Using the PLA composite fiber filament of the present invention causes little filter-tip suction resistance, smoke flows evenly, temperature reduction results are good, and strength is moderate.

La présente invention concerne un filament de fibres composites PLA, ainsi qu'une technique de préparation et une application associées. Un filament de fibres composites PLA selon la présente invention a une structure âme-gaine et comprend une couche d'âme interne et une couche de gaine externe enroulée à l'extérieur de la couche d'âme interne, la couche d'âme interne étant un filament continu, le matériau dont le filament est constitué étant un matériau dégradable, la composition de matériau de la couche de gaine externe étant principalement du PLA, PLA signifiant acide lactique polymérisé, et un canal d'écoulement d'air étant situé entre la couche d'âme interne et la couche de gaine externe. Les effets bénéfiques de la présente invention sont les suivants : le filament de fibres composites PLA selon la présente invention présente non seulement une bonne flexibilité, ne se rompt pas facilement et ne se délite pas facilement, mais est également complètement biodégradable, ce qui contribue à la protection de l'environnement. Le filament de fibres composites PLA selon la présente invention présente une faible résistance à l'aspiration à l'embout-filtre, permet des échappements uniformes de fumée, une réduction satisfaisante de la température et une résistance modérée.
