METHOD OF MANUFACTURING COATED SAILCLOTH COMPRISING ULTRA HIGH MILECULAR WEIGHT POLYETHYLENE FIBER AND HIGH STRENGTH POLYESTER FIBER

摘要

The present invention relates to a method for manufacturing a coated fabric for sailcloth. The coated fabric for sailcloth is manufactured by subjecting a fabric for sailcloth consisting of an ultra high-molecular polyethylene fiber and a high-strength polyester fiber to pretreatment, curing, tentering, resin coating, and thermosetting. In order to prevent the deterioration in physical properties of the ultra high-molecular weight polyethylene fiber, the curing treatment is performed at a temperature of 130-140, which is relatively lower than the curing temperature of the general high-strength polyester textile. Considering the deterioration in setting characteristics of the high-strength polyester due to the curing treatment, the width widening is minimized at the time of tentering and the thermosetting is conducted at a temperature of 100 or lower. The process for manufacturing a coated fabric for sailcloth of the present invention can effectively prevent the deterioration in physical properties of the ultra high-molecular weight polyethylene fiber contained in the coated fabric for sailcloth and effectively prevent the slow reduction in the width of the coated fabric for sailcloth during storage.
