Abstract

The invention relates to a preparation method of a swimsuit fabric. The preparation method comprises the steps of: firstly, preparing elastic polyester fibers, i.e., in the process of preparing roundside-by-side composite fibers from modified PET (which contains an antibacterial agent) and PTT according to an FDY process, changing spinneret orifices on a spinneret plate into a three-leaf shape from a round shape, adopting annular blowing cooling, controlling arrangement of the three-leaf-shaped spinneret orifices on the spinneret plate to meet a certain conditions and then carrying out relaxation thermal treatment to obtain the elastic polyester fibers; and then by using the elastic polyester fibers as a raw material, carrying out flow of antioxidation finishing (after attaching antioxidation finishing liquid to the elastic polyester fibers in an electrostatic spraying mode (a distance is 15 to 50mm, and a voltage is 30 to 100V), carrying out microwave treatment (a frequency is 80 to150MHZ, and time is 10 to 15min)), spinning, weaving and anti-ultraviolet-ray finishing so as to prepare the swimsuit fabric. The swimsuit fabric has an elastic elongation gamma 1 of 133 to 138% and an elastic recovery rate gamma 2 of 98 to 100%.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a preparation method of swimwear fabrics. Background technique [0002] Swimsuits generally use multi-material blended fabrics, the most common being nylon and ammonia, polyester and ammonia. Spandex is generally not used alone, but applied in an appropriate amount in the fabric to improve the stretchability of the fabric. Among them, the Lycra produced by the former DuPont Company in the United States can be stretched to 4 to 7 times the original length, and can quickly restore the original length after the external force is released; after it is blended with various fibers, the fabric can keep the fabric close to the body; The spandex content in swimsuits is about 15% to 20%, and such swimsuits can expand and contract freely with body movements. If the proportion of spandex is further increased, the dimensional stability of the fabric will deteriorate, because spandex w...
