Multi-filament polyester (polyethylene terephthalate, PET) yarn with a low-melt point of 60˚ C (140˚ F). Rather than being a detriment to durability, the low melt temperature of this yarn increases the strength and stability of a surrounding fabric. The textile will be composed of a standard yarn type with a higher melt temperature, or no melt temperature. The low-temp yarn is incorporated in a small percentage during the construction of the main fabric. After activation with heat, the yarn functions as an adhesive, binding together the surrounding yarns where they touch. By leveraging yarn format for incorporation of the bonding agent, the textile’s inherent properties, such as breathability, are not disrupted. The fiber is manufactured through melt spinning. Once in yarn form, it can be converted into textiles in the same manners — weaving, knitting, braiding, stitching, etc. — as the other yarns composing the bulk of the fabric. Yarn is sold on cones of 0.25 kg or 1 kg (0.5 lb. or 2.2 lb.), boxed and palletized. The most common yarn size is 167 dtex (150 Denier), but multiple deniers are available from 23 dtex–840 dtex. (21 Denier–756 Denier). The fiber is offered in both black and white to reduce visibility in the final product. Custom sizes and colors can also be provided. Both OEKO-TEXⓇ and REACH certifications have been achieved. Applications include footwear, apparel, accessories, industrial, automotive, and construction textiles.
