Hybrid yarns which include oil seed flax plant bast fiber and other fibers and fabrics made with such yarns

A thermoformable hybrid yarn comprising:

• at least two groups which are twisted together to form the yarn, the yarn comprising:
• a first fiber group which comprises oilseed flax plant bast fibers having have a length of from about 15 mm to about 75 mm, a tenacity of at least about 1.5 grams/Denier, a breaking elongation of from about 1 to about 20% and a crimp of from about 5 to about 80%;
• and
• a second filament group which comprises at least one thermoplastic filament having a melting point of at least about 10° C. and below the thermal decomposition point of the plant bast fibers, wherein the first and second group are ring spun to a yarn.

A method for making a hybrid yarn comprising at least two groups, a first fiber group and a second fiber group:

• mixing the first fiber group, the second fiber group, a hydrophobic lubricant, and a hydrophobic antistat to provide a lubricated fiber group;
• and
• spinning the lubricated group,
• the first fiber group comprising flax oilseed plant bast fibers having a tenacity of at least about 1.5 grams/Denier, a breaking elongation of from about 1 to about 20% and a crimp of from about 5 to about 80%,
• the second filament group being selected from the group consisting of synthetic fibers, natural plant fibers other than flax bast fibers and mixtures thereof, the second filament group having a fiber tenacity of above about 1.5 gram/Denier and a breaking elongation of from about 5 to about 75%, and
• the first fiber group and the second fiber group being in amounts effective for proving a yarn with a tenacity of at leat about 0.8 grams/Denier.
