Definitions
- the present disclosure relates to carpet with single yarn self-twisted loop piles that has an appearance and aesthetics similar to cut pile construction with improved durability and methods for making the same.
- BCF bulked continuous filament
- Twisted and heat set yarn is then stitched through a pre- constructed backing to form a loop or a tuft.
- the loop is cut on a tufting machine, thereby generating two tufts or pile for each loop. Loops can be cut in different patterns and styles creating the possibility of making carpets with both cut and loop pile with various designs.
- Cut pile carpets have a soft hand and a unique appearance and aesthetics, but lack durability due to untwisting of tufts caused by foot traffic. While loop pile carpets are more durable, they have a harsh hand and very different look from cut pile carpets.
- U.S. Patent Application No. US 2003/0165656A1 discloses a carpet fiber yarn comprising carpet fiber and binder fiber wherein the yarn is subjected to singeing to remove protruding fiber ends and heat to sufficiently melt the binder fiber.
- U.S. Patent No. 5,478,624A discloses a synthetic yarn made from a blend of base fibers selected from the group consisting of polyester nylon 6 and nylon 66 and 1-12 weight percent of a heat activated binder fiber having a melting point within the range of 165°C-190°C.
- U.S. Patent 6,782,686 discloses a method for forming a textured loop pile rug or carpet using torque created by twisting following by cabling and forming of a cable twist of multiple yarns.
- China Patent application No. CN1262346 discloses a device for preventing twisted yarn from crinkling.
- An aspect of the present disclosure relates to a carpet that has hand, appearance and aesthetics similar to a cut pile carpet but which exhibits much improved durability and texture retention as compared to standard cut pile carpet.
- the carpet of the present disclosure comprises single yarn twisted at a higher twist level than typically used which is stitched through a pre- constructed woven or nonwoven fabric backing to form a loop or a tuft. Loop pile gets automatically twisted due to live twist in single yarn,
- the single yarn is twisted in the range of 1 to 15 turns per inch (tpi). In one nonlimiting embodiment, the single yarn is twisted in the range of 3 to 12 tpi. In one nonlimiting embodiment, the single yarn is twisted in the range of 5 to 10 tpi.
- the single yarn is directly tufted into carpet without a yarn heat setting step.
- Another aspect of the present disclosure relates to a method for tufting a twisted single yarn without snarling.
- Single yarn with high twist level has natural tendency to form snarl which can cause machine stop and show as a defect in the carpet.
- yarn tension is controlled as the yarn unwinds from the package on the creel via a tension band around the package.
- the tension band is set so that yarn tension coming off the package is in the range of 0.001 grams per denier to 0.3 grams per denier.
- the tension band is set so that yarn tension coming off the package is in the range of 0.01 grams per denier to 0.1 grams per denier.
- yarn tension as it is coming off the package is controlled by using a sleeve or bag around the package.
- snarls are removed by subjecting the yarn right after unwinding from the package to tension in the range of 0.001 grams per denier to 0.3 grams per denier, more preferably, in the range of 0.01 grams per denier to 0.1 grams per denier.
- the method further comprises controlling yarn tension throughout the tufting process to prevent re-formation of snarls.
- FIGs. 1A and IB are representations of embodiments of the present disclosure inclusive of a self twisted loop pile carpet sample (FIG. 1 A) and a single loop (FIG. IB) from the carpet.
- FIGs. 2A and 2B are representations of embodiments of a standard cut pile carpet sample (FIG. 2A) and a single tuft (FIG. 2B) from the carpet.
- FIG. 3 is a schematic representation of an apparatus under in the present disclosure inclusive of a tension band around the yarn feed package on a tufting creel.
- Embodiments of the present disclosure will employ, unless otherwise indicated, techniques of chemistry, fabrics, textiles, and the like, which are within the skill of the art. Such techniques are fully explained in the literature.
- the present disclosure relates to carpet that has hand, appearance and aesthetics similar to a cut pile carpet but which exhibits much improved durability and texture retention as compared to standard cut pile carpet.
- the present disclosure also relates to methods for producing yarns and caipet.
- Synthetic yarns used in the manufacture of soft floor coverings are very frequently formed from two or more individual yarns, and these individual yarns are themselves formed from many constituent filaments.
- two or more yarns are twisted or "cabled” together, to form plied yarns having various properties useful in the construction of soft floor coverings. See, e.g. U.S. Patent 6,782,686.
- a standard cabling process involves physically rotating one yarn, fed from a creel, around a second yarn fed from a
- the carpet of the present disclosure comprises single yarn twisted at a higher twist level than is typically used.
- the twist level of the single yarn ranges from 1 to 15 turns per inch (tpi).
- the single yarn is twisted in the range of 3 to 12 tpi.
- the twist level of the single yarn ranges from 5 to 10 tpi.
- Yarn twisting in accordance with the present disclosure is performed with single yarn and without cabling or cable twist.
- Yarns comprising any synthetic yarn material, any natural fiber yarn material and/or combinations thereof can be used in the carpet of the present disclosure.
- Nonlimiting examples include yarns comprising polyesters, nylons and/or olefins, such as polypropylene and any combinations thereof.
- yarns of all fiber cross-sections and deniers per filament can be used.
- Examples of fiber cross-sections capable of being created include triangular (or "delta"), trilobal, round, tetragonal, pentagonal, octagonal, and irregular shapes.
- the fiber can be solid, or can have one or more voids running along the length of the filament.
- yarn with a denier ranging from 100 to 10000 can be used.
- yarn with a denier ranging from 400 to 3000 can be used.
- yarn with a denier ranging from 600 to 2000 can be used.
- the single twisted yarn can be directly tufted into carpet without a yarn heat setting step.
- the single twisted yarn is directly tufted into carpet by stitching through a pre-constructed woven or nonwoven fabric backing to form a loop or a tuft. Loop pile becomes self-twisted due to live twist.
- the present disclosure further provides a method for tufting of twisted single yarn. Twisted single yarn has very lively twist and a strong tendency to snarl. In the present disclosure, a method is provided for tufting twisted single yarn without snarling.
- yarn tension is controlled as the yarn unwinds from the package on the creel via a tensioning device such as a tension band as depicted in FIG. 3 around the package.
- the tension band comprises an elastic or self-retracting cord which can be wrapped around the yarn package to keep a certain minimum tension and prevent snarling in the yarn as it unwinds.
- the tension band wraps at least once around the yarn package, preferably on the front end.
- the tension band is held in place by attaching it to creel.
- the tension band is set so that yarn tension coming off the package is in the range of 0.001 grams per denier to 0.3 grams per denier.
- the tension band is set so that yarn tension coming off the package is in the range of 0.01 grams per denier to 0.1 grams per denier.
- yarn tension as it is coming off the package is controlled by using a sleeve or bag around the package.
- snarls are removed by subjecting the yarn right after unwinding from the package to tension in the range of 0.001 grams per denier to 0.3 grams per denier, more preferably, in the range of 0.01 grams per denier to 0.1 grams per denier. Desired yarn tension can be achieved by using commercially available hysteresis or other types of tensioner.
- the method further comprises maintaining yarn tension throughout the tufting process to avoid re-formation of snarls.
- FIGs. 1A and IB are representations of embodiments of the present disclosure comprising self twisted loop pile (FIG. 1 A) and a single tuft (FIG. IB) carpet.
- FIG. IB the loop 20 in self-twisted loop pile 15 is formed automatically during tufting due to the lively nature of twist in single yarn 25.
- Self-twisted loop pile formed in this way has hand, appearance and aesthetics similar to cut pile without having the drawback of untwisting of a single cut pile as shown in FIG. 2B.
- the carpet 10 of the present disclosure has exceptional durability and texture retention as compared to the cut pile carpet depicted in FIG. 2A.
