Abstract: A method for manufacturing fabric with flat screen and digital printed patterns includes: singeing, pretreatment, flat screen scraping sizing, drying, pattern printing, humidification, steaming treatment, washing, and non-ironing and soft setting. The pretreatment is a biological enzyme pretreatment process including: cloth feeding at 75° C., dipping, scouring and bleaching in a working fluid, heating to 90° C. for treatment of 30 minutes, draining, hot water washing and cold water washing. A shortened process flow can be realized, and the positioned sizing that uses a flat screen to scrape a sizing agent to a pattern position to be digital spray-printed on instead of traditional full-width sizing for sizing and printing, which greatly reduces the amount of sizing agent used, lowers production cost and reduces waste water pollution, and solves problem that the fabric is mottled caused by the application of sizing agent in areas without printed pattern due to full-width sizing.

Abstract: A bimodal three-dimensional mammary gland imaging quality detecting phantom and method, which includes: a three-dimensional breast appearance phantom structure made of agarose gel containing polyethylene, which is a radiation equivalent material of adipose tissues under X-rays, the relaxation time of hydrogen protons in the agarose gel under a 3T magnetic field is equivalent to that of human adipose tissues, and mammary gland tissue duct phantoms and phantoms of lobules of mammary gland are distributed in the breast appearance phantom structure. The phantom can be used for the image quality detection and analysis of mammary gland imaging by the systems of magnetic resonance and mammography, the material is elastic and can be compressed on a mammography platform for imaging, and the phantom can also be vertically placed in the magnetic resonance mammary gland coil for tomography, so two imaging modes of one phantom are achieved, and the application range is expanded.
