The present invention relates to a method for the production of polysaccharide fibers which, as a fiber-forming substance, comprise a mixture of cellulose and &#x3b1;(1&#x2192;3)-glucan, as well as to the fibers made thereof and to their use.

Polysaccharide fibers and method for the production thereof

The present invention relates to a method for the production of polysaccharide fibers having increased fibrillation tendency, which, as a fiber-forming substance, comprise a mixture of cellulose and &#x3b1;(1&#x2192;3)-glucan, as well as to the fibers made thereof and to their use.

Polysaccharide fibers with an increased fibrillation tendency and method for the production thereof

The present invention relates to a fiber of the Lyocell type which has a titer of from 0.8 dtex to 3.3 dtex and is characterized by the following relationships: The fiber according to the invention displays a specific combination of properties with regard to the H&#xf6;ller factors, the flexibility and the abrasion resistance within a planar assembly. Hence, the fiber shows a behavior more similar to viscose and can be processed in the textile chain according to viscose standard methods.

Cellulose fiber

The invention relates to flame-retardant cellulosic man-made fibers containing a flame-retardant substance in the form of an oxidized condensate of a tetrakis hydroxyalkyl phosphonium salt with ammonia and/or a nitrogenous compound which contains one or several amine groups whereby the fiber has a tenacity of more than 18 cN/tex in a conditioned state. Production process and the use of the fibers according to the invention are further objects of the invention.

Flame retardant cellulosic man-made fibers

The present invention relates to flame-retardant Lyocell fibers which include incorporated inorganic additives which are particularly suited for use in flame barriers for articles of manufacture, such as mattresses and upholstered furniture applications.
