Abstract

A lining fabric ( 3 ) for a clothing article ( 1 ). The lining fabric ( 3 ) is hygroscopic to ensure good wearing comfort, and has sufficient dimensional stability to allow washing in a household laundry machine. The lining fabric ( 3 ) is made from yarns ( 6 ) containing or consisting of Lyocell filaments ( 7 ). The Lyocell filaments ( 7 ) have an average linear density of less than 1.5 dtex, preferably less than 1.4 dtex and even more preferred, less than 1.3 dtex. The washing shrinkage after five washings is preferably less than 4% in each of two perpendicular directions.

First claim

The invention claimed is:

1. A lining fabric having at least one layer consisting of yarn, the yarn consisting of Lyocell filaments, wherein, in the conditioned state, the average linear density of the Lyocell filaments in the yarn is between 0.6 and 4 dtex, and wherein the lining fabric has a combined washing shrinkage after five washings of not more than 10%.

2. The lining fabric according to claim 1 , wherein each yarn has a linear density between 30 and 200 dtex.

3. The lining fabric according to claim 2 , wherein each yarn the washing shrinkage after five washings in one direction is not more than 3.5%.

4. The lining fabric according to claim 1 , wherein, in the conditioned state, the average dry tenacity of the Lyocell filaments is at least 30 cN/tex.

5. The lining fabric according to claim 1 , wherein, in the conditioned state, the average dry elongation at break of the filaments is at least 6%.

6. The lining fabric according to claim 1 , wherein the lining fabric is dyed.

7. The lining fabric according to claim 6 , wherein the dye is a reactive dye.

8. The lining fabric according claim 1 , wherein the yarn comprises a resin finish.

9. The lining fabric according to claim 1 , wherein the at least one layer of the lining fabric is woven and consists of or contains a weft yarn and a warp yarn as the yarn.

10. The lining fabric according to claim 9 , wherein the weft yarn is made of Lyocell filaments having a lower average linear density than the Lyocell filaments in the warp yarn.

11. The lining fabric according to claim 9 , wherein at least one of the warp yarn and the weft yarn is a ring yarn.

12. A clothing article having an inner side made of a lining fabric according to claim 1 .

13. A method of making a lining fabric of a clothing article, the method comprising producing the lining fabric of claim 1 .

14. A lining fabric having at least one layer consisting of yarn, the yarn consisting of Lyocell filaments, wherein, in a conditioned state, an average linear density of the Lyocell filaments in the yarn is between 0.8 and 1.5 dtex, and wherein the lining fabric has a combined washing shrinkage after five washings of not more than 10%.

15. A lining fabric having at least one layer consisting of yarn, the yarn consisting of Lyocell filaments, wherein, in a conditioned state, an average linear density of the Lyocell filaments in the yarn is between 0.8 and 1.5 dtex, and wherein the lining fabric has a combined washing shrinkage after fiver washings of not more than 10%, and wherein, in the conditioned state, an average dry tenacity of the Lyocell filaments is 37 cN/tex to 40 cN/tex.
