Skaifei is a Lingerie Production Firm built around a single engineering discipline: seamless knitting. Most apparel factories cut and sew fabric into garments, and most of the engineering work happens at the seam. Skaifei's engineering work happens at the knitting machine, where a circular knit program sets the gauge, the stitch density, and the compression gradient in a single pass — no seams, no cut-and-sew tolerances, no fabric waste at the edge. The factory has been running this model since 2008, with the production base in the Chaoyang-Gurao seamless apparel industrial cluster in Guangdong province, China, and a Moscow warehouse for CIS clients that handles the Eastern European and Russian markets.
