摘要:
Sklerenchym-Fasern, insbesondere Flachsfasern, die in einem gereinigten Verbund aus Elementarfasern vorliegen, die im wesentlichen in Erstreckungsrichtung des Verbundes ausgerichtet sind, werden durch Naßspinnen zu einem Faden hoher Festigkeit und geringen Fadengewichtes verarbeitet.

Selon l'invention, les fibres issues du teillage sont soumises aux opérations préalables suivantes :
a. coupe à une longueur comprise entre 150 et 400 mm, b. préimprégnation par de l'eau, c. action de la vapeur sous une pression comprise entre 10 et 15 bars pendant une durée comprise entre 20 et 60 secondes, d. détente à pression atmosphérique, e. lavage et séchage,
qui sont soumises aux étapes de préparation sur tout type de matériel : lin, laine ou coton; enfin le ruban de fibres obtenu est filé au mouillé. Le fil de lin obtenu a l'aspect et la structure d'un fil de lin au mouillé et a une souplesse le rendant apte à une utilisation en bonneterie, sur métier à tricoter.

The invention relates to the separation and recovery of components from vegetable raw materials. The invention provides a method for separating components from vegetable material which comprises at least leaf and/or stem parts, characterized in that the material is at the least partly fiberized and subsequently is separated into a fiber fraction and a juice stream, such that the fiber fraction principally comprises relatively firm tissues such as epidermis, sclerenchyma and vascular bundles, and the juice stream principally contains soft tissues such as parenchyma and cytosol. In a preferred embodiment, the invention provides a method for separating a juice stream which comprises in particular chloroplasts.

La présente invention a pour objet un procédé de traitement de matières fibreuses, notamment des plantes à fibres ou des fibres grossières, qui consiste à les mettre au moins une fois au contact d'un milieu fluide dont la température est inférieure à 250° Kelvin pendant un temps bref compris entre la fraction de seconde et quelques minutes, et à soumettre ces matières fibreuses à un procédé physique de séparation sélective de leurs différents constituants. Le procédé s'applique au traitement des plantes à fibres telles que le lin, chanvre, kenaf.
摘要:
Provided are: a homogeneous fiber board which has small variation in weight per square meter; and a method of the same. The present fiber board (100) is obtained by: mixing a vegetable fiber (1) (such as kenaf fiber) and a thermoplastic resin fiber (such as polypropylene fiber) to form a web; forming a fiber mat by needle punch method or the like to interlace the fibers that constitute the web; and heating and compressing the fiber mat. The vegetable fiber is crimped in advance by stirring a raw material fiber in presence of water. The present production method has: a web-forming process wherein a web is formed by mixing a vegetable fiber and a thermoplastic resin fiber; a mat-forming process wherein a fiber mat is formed by interlacing the fibers that constitute the web; and a board-forming process wherein a fiber board is formed by compressing the fiber mat with heating.
