Embodiment Construction

[0018] Preferably, fibers are produced from spinning dopes. It has been found that, despite the addition of at least one additive according to the invention, surprisingly no decomposition of the spinning dope occurs, especially when the spinning dope contains cellulose, and very particularly when the spinning dope When composed of cellulose, N-methylmorpholine-N-oxide (NMMNO) and water as the main components.

[0019] A suitable production process is known from DE 10 2007 054 702 A1, in particular for polymer compositions comprising cellulose or modified cellulose, especially in the form of shaped bodies.

[0020] The polymer compositions may comprise polymers and are used in the usual manner for the manufacture of fibres, threads, yarns, nonwovens, garments and medical aids such as bandages and compression stockings.

[0021] In a preferred embodiment, the polymer is selected from the group consisting of cellulose, modified cellulose, polyamide, polyacrylic acid, polyester, ...

Abstract

The invention relates to fibers and threads having an occlusion function. A polymer composition contains a polymer and at least one active substance selected from the group consisting of an active substance generating blocking, in particular an active substance generating an inner blocking or an active substance generating an outer blocking, a moisturizing agent, a pain or itch-reducing active substance and mixtures thereof.

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of March 13, 2015, an application number of 201580024257.3, and an invention title of "Fiber and Yarn with Obstructive Effect". technical field [0002] The present invention relates to a polymer composition comprising a polymer and at least one active substance, and to a shaped body having such a polymer composition; the use of the shaped body and the polymer composition; and the corresponding yarns, nonwovens, clothing and medical aids. Background technique [0003] Polymer compositions that "function" by additives are known. Thus, for example US-A 5,766,746 describes cellulose fibers comprising flame retardant components. DE 100 37 983 A1 describes polymer compositions with an alkaloid component and DE 100 07 794 A1 describes polymer compositions with materials from marine plants or animals. [0004] This polymer composition is further processed into ya...
