Abstract

It is disclosed a method of producing a yarn having the look and feel of natural fibers, the method comprising the steps of preparing a first plurality of man-made textile fibers or a second plurality of natural textile fibers, the first and second plurality of textile fibers being obtained from breaking the first or the second textile fibers under the effect of a mechanical force applied to the first or the second textile fibers. A final blend for producing the yarn, can be prepared by adding the first plurality of textile fibers to a plurality of man-made fibers, or by adding the second plurality of textile fibers to a plurality of man-made fibers, or by adding the first plurality of textile fibers to the second plurality of textile fibers.

First claim

The invention claimed is:

1. A yarn comprising
a blend of fibers of yarns comprising
a plurality of noils of man-made textile fibers, wherein the content of fibers whose length is less than 12.7 mm is at least 5% by weight, and said blend further comprises
a plurality of man-made fibers in staple form,
wherein said blend has a coefficient of variation (CV %) of the length distribution of fibers which is higher than the coefficient of variation (CV %) of the length distribution of the plurality of man-made fibers in staple form, and wherein the plurality of man-made fibers in staple form are regenerated cellulosic fibers and the noils have a neps count between 50 and 300 count/gram.

2. A yarn according to claim 1 , wherein the length distribution of the fibers in the final blend of fibers is defined by a coefficient of variation (CV %) of at least 25 percent.

3. A yarn according to claim 1 , wherein the noils have a length comprised between 4 and 38 mm.

4. A yarn according to claim 1 , wherein the content of fibers having the length less than 12.7 mm in the noils is between 5 and 65 percent by weight.

5. A yarn according to claim 1 , wherein the coefficient of variation (CV %) is calculated as a function of the numberwise average fiber length (Ln) of the textile fibers.

6. A yarn according to claim 1 , wherein the yarn comprises virgin man-made fibers mixed together with the noils of man-made fibers.

7. A yarn according to claim 6 , wherein the virgin man-made fibers mixed together with noils of man-made fibers comprise fibers having different denier and/or different cross-section shape.

8. A yarn according to claim 6 , wherein the noils are of man-made fibers in staple form.

9. A yarn according to claim 8 , wherein the noils are chosen from regenerated cellulosic fibers, the regenerated cellulosic fibers being chosen from lyocell, viscose, modal, cupro, bamboo, polynosic fibers, or acetate.

10. A yarn according to claim 1 , wherein slubs in the yarn are provided.

11. A yarn according to claim 1 , wherein the noils of said plurality of noils of man-made textile fibers have a length comprised between 4 mm and 38 mm, a content of fibers whose length is less than 12.7 mm comprised between 5 and 65 percent by weight and coefficient of variation (CV %) of the length distribution between 25 and 80 in percentage.

12. A fabric comprising the yarn according to claim 1 .

13. A garment comprising the fabric according to claim 12 .
