Focus On Thread For 20 Years
Filament Thread
Filament Thread will not fray, unravel or break when sewing at high speeds that results in stitching evenly and smoothly, even while quilting several thick layers of fabric together. Therefore, the thread manage to handle all hard tasks for tough fabric.
Bonded Thread
Bonding refers to the process of coating a thread in a resin placed on the thread to add strength and heat tolerance to prevent knots, snapping, and tangles when densely sewing at high speeds. Therefore bonded thread is stronger than regular thread and the best option for tough material.
Embroidery Thread
Our embroidery thread refers to machine embroidery thread made from polyester filament. As the most popular go-to thread choice for embroidery, the thread has outstanding strength and durability to perform densely at multi-direction or through multi-layers without any damage, plus color fastness and gorgeous luster.
PLA Yarn And Thread
Polylactic acid (PLA) is a biopolymer material produced through the fermentation of biomass sources like corn, beets, sugarcane, and straw cellulose, resulting in the polymerization of small molecules of lactic acid. The fibers made from PLA raw materials using spinning techniques are a novel and eco-friendly type of fiber.
PTT Yarn
PTT is a type of synthetic fiber made from a polymer known as polytrimethylene terephthalate, versatile and suitable for a wide range of applications that demand flexibility, durability, and comfort, including swimwear, yoga pants, leggings, undergarment, furniture upholstery and bedding.
