KB SEIREN is engaged in the sale of yarns and garment textiles. In yarn marketing, we utilize the flexibility of Hokuriku Synthetic Fibers Plant, which allows small-lot manufacturing of diversified products, to shift to differentiated yarns developed with our original technology. As for the textiles business, we focus on the markets for "sportswear," "inner wear" and "clothing materials" to enhance our direct approach to apparel makers.
