AI Technical Summary

Benefits of technology

The invention relates to a process for obtaining a usable yarn from longer staple fibers made of collagen. The fibers should be at least 15 mm in length, but shorter fibers can also be used in the yarn. This designation is important because it ensures that a sufficient amount of the collagen-based fibers are longer than the designated length. The technical effect of this invention is the production of a yarn with improved properties that can be used in various applications.

Problems solved by technology

A challenge is however that the natural fiber sources, when used exhibits inferior properties e.g. in relation to strength and other relevant properties when used e.g. in relation to yarn spun from these fibers.

Embodiment Construction

[0079]In this description and claims, the percentage values relating to an amount of material are percentages by weight (wt. %) based on the total weight of the filament or the staple fiber in question unless otherwise indicated. Word “comprising” may be used as an open term, but it also includes the closed term “consisting of”.

[0080]In the current application term “fiber product”, when used refers to fibrous filaments or staple fibers.

[0081]The term “staple fiber” refers to fibers of discrete length, such as shortened fibrous filaments. The staple fibers include individual fibrils interlocked together. The fibrous filament may be shortened into staple fibers of a certain length.

[0082]The staple fibers may be further processed in order to provide an item, such as a yarn or a non-woven material.

[0083]The fibrous filaments and / or staple fibers may be used for forming items of textile and / or shoe industry. Items include, for example, yarns, fabrics, woven materials, non-woven materials...

Abstract

Disclosed embodiments describe a reconstructed filament comprising natural protein fibrils and an additive. Disclosed embodiments also describe a wool comprising: a plurality of staple fibers formed of reconstructed filaments, wherein the reconstructed filaments comprise natural protein fibrils and an additive. Disclosed embodiments also describe a yarn spun from staple fibers, the yarn comprising: staple fibers comprising reconstructed filament, wherein the reconstructed filament comprises natural protein fibrils and an additive. Disclosed embodiments also describe an item comprising a reconstructed filament, wherein the reconstructed filament comprises natural protein fibrils and an additive.

Description

FIELD OF THE INVENTION[0001]The invention relates to a filament and yarn produced on the basis of a natural proteinBACKGROUND OF THE INVENTION[0002]There is an increasing interest to replace or reduce the use of fossil based materials with bio-based and renewable materials so as to support environmental sustainability. The development and use of renewable raw materials can help to reduce the usage of fossil resources. A challenge is however that the natural fiber sources, when used exhibits inferior properties e.g. in relation to strength and other relevant properties when used e.g. in relation to yarn spun from these fibers.SUMMARY OF THE INVENTION[0003]The invention relates to a reconstructed filament wherein the reconstructed filament comprises natural protein fibrils and an additive.[0004]In the present context, the additive designates an additive which is bonding distinct natural protein based fibrils. Additive(s) added onto the surface of the reconstructed protein fiber filame...
