Abstract

The invention relates to a knit fabric. There is a need for knit fabrics made that are comfortable to wear, have good washability and high softness. Good washability implies both dimensional stability of the fabric and maintaining positive surface aspects such as hairiness, pilling and fiber splice even after several washings. This object is solved according to the invention by a knitted fabric made from at least one yarn which consists of or contains lyocell filaments. The resulting fabric has a high wearing comfort and superior mechanical qualities.

Claims

exact text as granted — not AI-modified
1 . A knit fabric made from at least one yarn which contains or consists of lyocell filaments. 
     
     
         2 . The knit fabric according to  claim 1 , wherein the yarn comprises at least 10% lyocell filaments. 
     
     
         3 . The knit fabric according to  claim 1 , wherein the yarn has at least 2000 TPM. 
     
     
         4 . The knit fabric according to  claim 1 , wherein the combined shrinkage of the knit fabric after one to five washings is less than 10%. 
     
     
         5 . The knit fabric according to  claim 4 , wherein the combined shrinkage of the knit fabric after one to five washings is less than 5%. 
     
     
         6 . The knit fabric according to  claim 1 , wherein the spirality over 50 cm is less than 20 mm after one washing. 
     
     
         7 . The knit fabric according to  claim 1 , wherein the hairiness of the knit fabric has a grade not worse than 3 in the original state. 
     
     
         8 . The knit fabric according to  claim 1 , wherein the knit fabric has a grade of not worse than 4 in a Martindale pilling test after 1000 and/or 2000 cycles and/or not worse than 3.5 after 5000 cycles in the original state and/or after five washings. 
     
     
         9 . The knit fabric according to  claim 1 , wherein the knit fabric scores at least 40000 cycles no destruction and/or to hole formation in a Martindale abrasion test. 
     
     
         10 . The knit fabric according to  claim 1 , wherein the fabric is dyed with at least one of a reactive, vat, sulphur and direct dye. 
     
     
         11 . The knit fabric according to  claim 10 , wherein the dye used is at least one of a bifunctional and a multifunctional dyestuff, and wherein the cellulose in the yarn is cross-linked. 
     
     
         12 . The knit fabric according to  claim 1 , wherein the fabric is resin finished. 
     
     
         13 . The knit fabric according to  claim 1 , wherein the fabric is a peach skin fabric. 
     
     
         14 . A textile article, comprising a knit fabric according to  claim 1 . 
     
     
         15 . A yarn containing or consisting of lyocell filaments. 
     
     
         16 . The knit fabric according to  claim 1 , wherein the spirality over 50 cm is less than 25 mm after five washings. 
     
     
         17 . The knit fabric according to  claim 1 , wherein the hairiness of the knit fabric has a grade not worse than 3 after one washing. 
     
     
         18 . The textile article according to  claim 14 , wherein the article is a garment.
