    摘要： A support garment may have a seamless support garment configured for use by a person. The garment may have first and second arm openings configured to be about 0.5 to 1 times greater than a diameter of an average user's arms; a neck opening configured to be about 2 to 4 times greater than a diameter of an average user's neck; a portion of the arm openings and neck opening opposite each other form integral shoulder straps; a band configured to fit at an under bust of the user defining a torso opening; two cup regions positioned above the band to receive the user's breasts, two cup regions positioned above the band to receive the user's breasts, the cup regions being 100-200 percent thicker at a portion of the cup configured for placement of the user's nipple and tapering to a garment body thickness as the taper extends away from the nipple portion; wherein, the support garment is configured from a material having between 50-200 percent elasticity.

    摘要： A high-strength high-modulus polyimide fiber and its preparation method pertain to the technical field of high-performance organic fiber. This fiber includes the polyimide (PI) fiber made from 3,3′,4,4′-biphenyl tetracarboxylic diandhydride (BPDA), p-phenylenediamine (pPDA) and 2-(4-aminophenyl)-1H-benzimidazol-5-amine (BIA), wherein the molar ratio between PPDA and BIA is 1:10˜3:1. During the synthesis, other diamine and diandhydride monomers may also be added. In the preparation process, the gradient temperature reaction method and one-step continuous preparation method are adopted, the synthesis and processing difficulty caused by the increase of the content of BIA is overcome, the problem of poor uniformity and stability of fiber is solved and PI fiber with high strength and high modulus is obtained. Its strength may reach 4.5 GPa and modulus may reach 201 GPa. Moreover, the sources of the raw materials are extensive, the spinning process is continuous, the cost is low, the efficiency is high and industrial production may be realized.
