1000M Cone Embroidery Thread * Colorfast - Five year dye lot guarantee * High Sheen Polyester * Premium Tensile Strength * 40wt. A high sheen, high tensile strength, lubricated embroidery thread which results in excellent production and adds magnificent color and luster to your finished products. All phases of the manufacturing process are performed in-house to insure quality. Employees are thoroughly trained on the use of the equipment and internal procedures to maintain high level of quality. Each cone is coded so that a lot number, machine, and operator can be identified if necessary. Each lot of new raw material is inspected and tested to make certain the quality of materials going into production are sufficient for producing a quality product. The same is true for finished products. An internal lab is used to test random samples of raw materials and finished cones, for control reasons. Furthermore, an independent, international testing lab is used to measure the quality of threads with respect to tensile strength and color fastness. No environmentally harmful products or carcinogens are utilized in production. All water used to dye the thread is properly treated to separate dye stuff from the water used in production. The inert sandy, grit material which remains is used as a land fill substance to help fight erosion along the coastlines. The use of certain dyes may change in order to adhere to environmental safety regulations. Commitment to quality includes the safety of our customers and our planet.
