  • the preferred characteristics of spun- dyed viscose fibers are from 1.3 to 1.7 dtex fiber fineness and a fiber length in the same range than the fiber length of the Lyocell fiber component.
  • the sparkling wipe blends according to the invention are suitable for baby wipes, facial cleaning wipes, intimate wipes, household wipes, sanitary products and facial mask.
  • the sparkling wipe blend according to the invention can be in the form of fiber bales (which is the usual form for the transport of staple fibers) wherein a bale contains both fiber components already blended before compressing.
  • the blend may be prepared from bales which contain only one fiber component during the so-called "opening" or before or during carding of the opened fibers of the different components.
  • nonwoven products for hygiene applications are - among others - wet wipes, hygiene wet wipes, flushable wipes, facial masks, top sheets, baby diapers, female pads, pantyliners, and incontinence products.

  • thermobonding step is needed to produce the nonwoven fabric.
  • the processability of the blended fibers on the non-woven facility enables running with full capacity because the cellulosic fibers stick together much better than blends of cellulosic with synthetic fibers. Therefore by using lyocell fiber instead of the synthetic fiber in the fiber blend, the tenacity of the resulting nonwoven is significantly higher which result in a better processability for example in the spun lace machines.
  • top-sheets made using the fiber blends according to the invention enable better comfort for females and baby skin and therefore support a healthier skin.
  • Colorful face masks can be produced by using the fiber blends
  • Such face masks support the regeneration of the skin cells.

These pigments are medically approved for the sanitary clean products.
  • Dispersants for the dyes used for spindyeing the fibers according to the invention have to also be in agreement with FDA and INCI list. Allowed dispersants are: Dimethylolpropionic acid, Phosphorilated tall oil fatty acids, Propanoic Acid, Siloxanes and Silicones (Cethylmethyl, dimethyl, methyl 11- methoxy-11-oxoundecyl), Trimethylolethane, Trimethylolpropane.

Abstract

L'invention concerne un mélange fonctionnel de fibres Lyocell et de fibres de viscose teintes dans la masse avec des pigments incorporés approuvés selon les normes FDA et INCI. En particulier des mélanges de fibres non tissées très homogènes peuvent être produits. Les fibres de viscose teintes dans la masse contiennent des pigments approuvés selon les normes FDA et INCI comme le bleu de cuve 1, le rouge pigment 170, le rouge 121, le jaune 83, le violet 23, le jaune 1, le jaune 110, le jaune 3, le jaune 74, le rouge 146, le rouge 2, le bleu 15:3, le bleu 15, le vert 7, le noir 7, le rouge 254. Ces fibres satisfont aux spécifications de la Pharmacopée Européenne selon la norme 01/2008:0034 (version 6.0). Les fibres Lyocell peuvent contenir, par exemple, des agents actifs tels que du ZnO ou de l'argent à des fins de fonction antibactérienne. Les mélanges de fibres selon l'invention peuvent être utilisés pour des lingettes (toilette intime, soins du visage, soins de bébé, nettoyage), pour des masques du visage, pour des feuilles de dessus et des parties ADL pour produits d'hygiène féminine, pour couches de bébé et pour produits d'incontinence. Ces mélanges de fibres permettent d'excellentes performances de gestion de lotion.
