At Ujyo Bussan Co., Ltd., we continue to develop and expand our "Refinement Sewing Thread Color Sample" with a focus on 100% cotton machine threads and cotton/polyester core yarns. By bringing together standard colors and years of experience, we cater to alteration jeans shops and jeans apparel manufacturers with thicker count machine thread. In addition, we also offer a specialty service for demanding needs with a low-quantity special order service of 40 to 60 cones. From the materials, choice of color, color bleeding and product sample, to the after treatment color and texture, we take all of your requirements into consideration.
Color Sample
	The bule "Refinement Sewing Thread COLOR SAMPLE FOR DENIMS & PROFESSIONALS" is a complete industrial machine thread color card that specializes in thicker count threads (#0-#50) for jeans. For designers and sewing manufacturers, this is an invaluable resource. Especially relating to UJ Core Yarn, it is possible to confirm a thread's exact width as sample threads of each thread count and color are included. Every thread gauge, material construction, special characteristics, and notice of usage is clearly marked so this Color Sample can be used as a resource when choosing a thread. A complete description in English is also included. To Enlarge Image
