Abstract
An artificial down filling material comprising artificial down clusters (1), wherein each of the down clusters (1) comprise a number of filaments (10) arranged side by side in a bundle, the filaments (10) being bonded, preferably melt bonded, together at a bonding location 20, wherein the filaments (10) are self-crimped, multi-component filaments (10), the cross-section of the multi-component filament having at least three corners (211).
Claims21
An artificial down filling material comprising artificial down clusters, wherein each of the down clusters comprise a number of filaments arranged side by side in a bundle, the filaments being bonded together at a bonding location, wherein the bonding location is between the ends of the filaments, whereby the down clusters have free filament ends at each of the ends of the bundle, wherein at least 50% by weight of the total amount of filaments are self-crimped multi-component filaments, the cross-section of at least 50% by weight of the total amount of the multi-component filaments having at least three corners, and wherein the bundle of filaments optionally is textured.
An artificial down filling material comprising artificial down clusters and artificial feathers, wherein each of the down clusters comprise a number of filaments arranged side by side in a bundle, the filaments being bonded together at a bonding location, wherein the bonding location is between the ends of the filaments, whereby the down clusters have free filament ends at each of the ends of the bundle, wherein at least 50% by weight of the total amount of filaments are self-crimped multi-component filaments;
- optionally the artificial down filling material comprising 60 to 95% by weight of artificial down clusters and 5 to 30% by weight of artificial feathers.
A method for providing an artificial down filling material, the artificial down filling material comprising artificial down clusters, wherein each of the down clusters comprise a number of filaments arranged side by side in a bundle, the bundle of filaments optionally being textured, the filaments being bonded together at a bonding location, wherein the bonding location is between the ends of the filaments, whereby the down clusters have free filament ends at each of the ends of the bundle, wherein at least 50% by weight of the total amount of the filaments are self-crimped, multi-component filaments, the cross-section of at least 50% by weight of the total amount of the multi-component filaments having at least three corners, said method comprising:
- bonding filaments in a yarn, the yarn optionally being textured, at bonding locations along the longitudinal extension of the yarn, wherein the yarn comprises at least 50% by weight of the total amount of filaments (10) being self-crimped, multi-component filaments, the cross-section of at least 50% by weight of the total amount of the multi-component filaments having at least three corners;
- and
- cutting the yarn in between the bonding locations to provide bundles of the filaments arranged side by side, each of the bundles having free filament ends at each of the ends of the bundles, whereby providing the artificial down filling material.
