Abstract: A method of manufacturing a wool-like yarn from continuous filaments of polymer material comprises steps of: providing partially oriented, continuous filaments of the polymer; drawing and air texturizing the partially oriented filaments to form threads, wherein a first group of straight filaments forms a core of the thread and a second group of filaments are overfed with respect to the first group of filaments to form a hairy sheath; and twisting or cabling a plurality of the threads together to form the wool-like yarn to have a weight of greater than 2000 dtex. The resulting wool-like continuous filament yarn is intrinsically UV resistant, antistatic and recyclable.

Abstract: A polymeric yarn composition having antimicrobial and/or antibacterial properties includes: (i) an herbal masterbatch, and (ii) a base polymer. The base polymer may include one of polybutylene terephthalate (PBT) or polyethylene terephthalate (PET), or polyamides, or polypropylene. Further, the herbal masterbatch may include: (a) an herbal component includes Neem or Turmeric or extract or combination thereof, and (b) a carrier polymer. The carrier polymer may be the same as the base polymer and may include one of: PBT, PET, polyamides or polypropylene. To make a polymeric yarn, the herbal masterbatch and the base polymer may be melted and extruded together to obtain the polymeric yarn having the herbal component in a range of 0.01% to 10% by weight of the polymeric yarn.

Abstract: Disclosure provides a twisted and heat-set Bulked Continuous side-by-side bi-component Filament (BCF) yarn including a plurality of side-by-side bi-component filaments, each includes first and second polymer components. The first polymer component forms a first side of the side-by-side bi-component filaments, and includes polybutylene terephthalate (PBT) in at least 25 and up to 75 volume percent of the filament in the BCF yarn. Further, the second polymer component forms a second side of the side-by-side bi-component filaments, and includes one of polyethylene terephthalate (PET) or polylactic acid (PLA) in at most 75 and down to 25 volume percent of the filament in the BCF yarn. The twisted and heat-set BCF yarn is obtained by a single-step continuous process, and subsequently followed by steps of twisting and/or cabling and heat-setting.

Abstract: The present disclosure discloses a high resilience and stain resistant bulked continuous filament yarn. The yarn comprises a plurality of continuous filaments of polybutylene terephthalate (PBT), wherein the polybutylene terephthalate (PBT) has intrinsic viscosity in the range of 0.8 to 1.3. The yarn is obtained by a process comprising melt spinning of the plurality of continuous filaments of PBT; extrusion of the plurality of continuous filaments; quenching of the extruded filaments; drawing of the quenched filaments; texturizing of the drawn filaments; cooling of the texturized filaments, overfeeding of the cooled-texturized filaments; and winding of the overfeed filaments with or without tangling for obtaining the high resilience and stain resistant bulked continuous filament yarn. The high resilience and stain resistant bulked continuous filament yarn has a stain resistance rating of more than 3 and a hexapod rating of 2 or more after 12000 cycles.

Abstract: A polymeric yarn composition having antimicrobial and/or antibacterial properties includes: (i) an herbal masterbatch in a range of 0.01% w/w to 10% w/w, and (ii) a base polymer in a range of 90% w/w to 99.99% w/w. The base polymer may include one of polybutylene terephthalate (PBT) or polyethylene terephthalate (PET), or polyamides, or polypropylene. Further, the herbal masterbatch may include: (a) an herbal component includes Neem or Turmeric or combination thereof in a range of 1% w/w to 75% w/w, and (b) a carrier polymer in a range of 25% w/w to 99% w/w. The carrier polymer may same as the base polymer and may include one of: PBT, PET, polyamides or polypropylene. To make a polymeric yarn, the herbal masterbatch and the base polymer may be melted and extruded together to obtain the polymeric yarn having the herbal component in a range of 0.01% to 10% in weight of the polymeric yarn.

Abstract: A process is described wherein pile yarn is woven with cotton weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve the PVA fibers. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn, corresponding to an increase in the air space in the pile yarn. By increasing the air space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels. The present invention further relates to pile yarn in terry woven fabric (warp yarn), or weft yarn, in the case of flat fabrics.

Abstract: Processes for forming embossed terry towels and the resulting towels are described herein. The towels have an uneven surface. Thus, the background can be at one height, and the design can be at another height, which is typically higher than the background. The process involves twisting the pile warp that will be used for the design on the towel with PVA filament yarn. The remaining pile warp, which is used to form the background, is 100% cotton. The pile warp is then woven with the ground warp and weft warp to form the towel. The towel is subject to a steaming process, which shrinks the PVA/cotton pile fibers, but does not affect the 100% cotton fibers. The PVA/cotton pile fibers shrink to at least about 50% of their original length under tension free conditions. The towel is then subjected to shearing to produce a velour texture. Due to the shrinkage of the PVA/cotton pile yarns, only the background (100% cotton) pile is cut, and the shrunk pile remains uncut.

Abstract: Towels which produce little to no lint (herein referred to as “lint-free”) and methods for making such towels are described herein. The lint-free towels contain a small amount of short cotton fibers in the pile yarn and the pile yarn contains a low twist factor. In the preferred embodiment, 24% or more of the noil is removed when the pile yarn is produced. This combination of low twist factor with few short cotton yarn, results in soft, absorbent, lint-free towels. Preferably, the lint-free towels contain yarn with a hairiness index of 5 to 7.5. The lint-free towels are produced by twisting the pile yarn with a poly vinyl alcohol (PVA) spun yarn. After weaving the yarns to form a towel, the PVA yarn is then dissolved during the production process, leaving twistless pile yarn.
