Manufacturing method of fabric for sunscreen blind using Non coating yarn and the fabric material for sunscreen blind and the sunscreen blind thereof

摘要

The present invention relates to a method for weaving a sunscreen blind fabric using an uncoated yarn. According to the present invention, uncoated yarn-based warp and weft threads that have different low melting fiber mixing ratios are used so that sunscreen blind migration, running, and chalking can be dealt with and its drapability can be improved. In addition, the weaving method is to achieve an openness factor of less than 4% based on the utilization of plain weaving using a two-ply body free from warp thread overlapping and twisting. The present invention also relates to a sunscreen blind fabric and a sunscreen blind. In the warp/weft thread- and plain weaving-based sunscreen blind fabric according to the present invention, the warp and weft threads are based on uncoated yarns and have different low melting fiber (LM) mixing ratios. In the case of the warp thread, the LM yarn is mixed at a thickness ratio of 0.05 D1 to 0.08 D1 in the warp thread thickness D1. In the case of the weft thread, the LM yarn is mixed at a thickness ratio of 0.20 D2 to 0.3 D2 in the weft thread thickness D2. The LM yarn mixing ratio is controlled such that the warp/weft thread thickness difference does not exceed 20% and the total ratio of the LM yarn in the woven fabric is maintained within a range of 10 to 20 percent by volume. According to the present invention, a sunscreen blind fabric can be woven that ensures an openness factor of less than 4%, deals with migration, running, and chalking, and is improved in terms of drapability.
