Title
(EN) NONWOVEN WEBS COMPRISING POLYSACCHARIDES
(FR) COUCHES NON TISSÉES COMPRENANT DES POLYSACCHARIDES
Abstract
(EN)
Disclosed herein are nonwoven webs comprising a nonwoven substrate and a binder comprising a polysaccharide. In one embodiment, the polysaccharide can comprise poly alpha-1,3-glucan, a poly alpha-1,3-glucan ether compound as disclosed herein, a poly alpha-1,3-glucan ester compound as disclosed herein, a graft copolymer comprising a backbone comprising dextran and poly alpha-1,3-glucan side chains, a crosslinked graft copolymer comprising a backbone comprising dextran and poly alpha-1,3-glucan chains, or a mixture thereof. Also disclosed are articles comprising the nonwoven webs, and methods of making the nonwoven webs.
(FR)
L'invention concerne des couches non tissées comprenant un substrat non tissé et un liant comprenant un polysaccharide. Selon un mode de réalisation, le polysaccharide peut comprendre du poly alpha-1,3-glucane, un composé d'éther de poly alpha-1,3-glucane tel que décrit ici, un composé d'ester de poly alpha-1,3-glucane tel que décrit ici, un copolymère greffé comprenant un squelette comprenant des chaînes latérales de dextrane et de poly alpha-1,3-glucane, un copolymère greffé réticulé comprenant un squelette comprenant des chaînes de dextrane et de poly alpha-1,3-glucane, ou un mélange de ces derniers. L'invention concerne également des articles comprenant les couches non tissées et des procédés de fabrication des couches non tissées.
