Claims24
A method for forming a textured loop style flooring article comprising:
- twisting a first yarn end with a second yarn end using a first twist forming a third yarn end;
- cabling two third yarn ends in a same direction as the first twist of the first yarn end and the second yarn end using a cable twist forming a final yarn, wherein a differential twist occurs between the first twist and the cable twist imparting a torque to the final yarn creating a textured effect in the final yarn, wherein the final yarn comprises a denier of about 2000 to about 20,000;
- and
- tufting the final yarn in a loop pile construction of a flooring article having the textured effect.
A method for forming a textured loop style flooring article comprising:
- twisting at least one feed yarn end with a second feed yarn end using a first twist forming a third yarn end;
- twisting a fourth feed yarn end with a fifth feed yarn end using the first twist forming a sixth yarn end;
- cabling the third yarn end and the sixth yarn end together in a same direction as the twisting of the yarn ends in forming the third yarn end and the sixth yarn end using a cable twist forming a final yarn, wherein a differential twist occurs between the first twist and the cable twist imparting a torque to the final yarn creating a textured effect in the final yarn, wherein the final yarn comprises a denier of about 2,000 to about 20,000;
- and
- tufting the final yarn in a loop pile construction of a flooring article having the textured effect.
A flooring article having a textured effect comprising at least two first yarn ends twisted together with a first twist forming a third yarn end, said third yard end and another at least two-ply yarn end twisted together with a cable twist in the same direction as the first twist creating a final yarn;
- a differential twist occurring between the first twist and the cable twist imparts a torque to said final yarn for a textured effect;
- and said final yarn being tufted into a loop pile construction, wherein the final yarn comprises a denier of about 2,000 to about 20,000.
