Problems solved by technology

[0002] Polybutylene terephthalate (PBT) in the prior art is a kind of synthetic chemical material, also is a kind of synthetic chemical fiber textile material, develops quite rapidly since industrialization, is widely used in many fields, especially In recent years, with the deepening of research on modified PBT, the scope of application of PBT has been further broadened. Reason: Due to the disconnection of the industrial chain between industries, and the previous production of PBT fabrics, the fiber strength is relatively lower than that of polyester fibers, and it is easy to fluff and pilling, resulting in weaving difficulties. , Insufficient toughness has become a major obstacle to the promotion and application of PBT fabrics. Therefore, the research on the enhancement and toughening of PBT and the optimization of the dyeing and finishing process are important contents of the high functionality of PBT fabrics.

Abstract

The invention relates to an elastic fiber fabric, in particular to an elastic fiber fabric and a preparation method thereof. Warps and wefts are respectively 150D or75D PTS elastic yarns. The elastic fiber fabric is prepared through the steps of winding, twisting, sectional warping, healding, weaving, blank inspection, unrolling and flattening, pre-shrinking treatment, presetting, dyeing, reduction clearing and finishing. The elastic fiber fabric and a preparation method thereof have the advantages as follows: the structure is simple, the chemical fiber differentiation is promoted, the added value is increased, the preparation steps are scientific and reasonable and conform to the basic state policy of energy conservation and emission reduction, and the fabric feels like nylon, has a bright and pure color, is far lower than spandex in price and is a preferred garment material.
