PURPOSE:The titled high-performance product containing a boron compound and an organosilicon compound in specific ratios, respectively, stably producible without deteriorating physical properties and spinning properties, having high melt dropping properties, slightly igniting in case of touch with fire, having improved flameproofing properties. CONSTITUTION:A fiber structure such as multifilament yarn, woven fabric, knitted goods, etc., consisting of polyester yarn comprising mainly polyethylene terephthalate, is incorporated with 0.5-5mol calculated as B atom based on constituent unit of polyester or a boron compound (e.g., orthoboric acid, etc.) and 1-30wt% based on polyester of an organosilicon compound (preferably polyorganosiloxane diol, etc.,), to give the aimed product. To obtain the polyester constituting the product, preferably polyesters containing the boron compound and the organosilicon compound, separately are blended before spinning is completed and spun. |
