The invention relates to a wool, cotton and cotton polyester interweaving weft knitting double-faced pile fabric. According to the fabric, pure-cotton silvalin is adopted as looped pile inner yarn, wool is adopted as middle connection yarn, cotton polyester silvalin is adopted as surface layer yarn, the pure-cotton silvalin, the wool and the cotton polyester silvalin are woven on a single-face circular weft knitting fleece machine to form a stitched looped pile fabric, in the weaving process, the wool middle connection yarn generates wool exposed points on the outer surface of the cotton polyester fiber surface layer, and the wool exposed points account for 30-33% of the area of the cotton polyester fiber surface layer; the looped pile inner yarn is napped, the wool exposed points are sanded to obtain the weft knitting double-faced pile fabric with the pure-cotton gigging inner layer, the wool connection layer, the cotton polyester surface layer and the wool felt layer, wherein the pure-cotton silvalin accounts for 52-57%, the wool accounts for 7-22% and the cotton polyester silvalin accounts for 22-27%. The fabric has the advantages of being fine in suede, high in wool touch, soft and full in hand touch, good in heat retention property, good in breathability, good in mold holding nature, capable of resisting static electricity and low in price.

The invention discloses an endometrium biopsy tool, a biopsy tool preparation device and a preparation method, and relates to the technical field of medical instruments. The biopsy tool includes a sampling device and a protection device, the sampling device and the protection device use TiB 2 / Al 2 o 3 Made of ceramic composite material, the sampling device includes an operating rod, the inner end of the operating rod is provided with a sampling spoon, the inner edge of the sampling spoon is provided with a scraper, and the outer end of the operating rod is provided with an operating handle, The protection device includes a protection tube, the inner end of the protection tube is provided with an expansion head, the length of the operating rod is greater than the length of the protection device, and the operating handle enters from the inner port of the expansion head The protective tube protrudes from the outer port of the protective tube, and the operating rod inside the protective tube is provided with a support ball. The biopsy tool has the advantages of simple structure, convenient use, small trauma and the like.

The invention discloses a solar water heater heat collection pipe and relates to the technical field of solar energy. The solar water heater heat collection pipe comprises an outer pipe body and an inner pipe body. A vacuum layer is formed between the outer pipe body and the inner pipe body. The inner pipe body is a sleeve formed by pressing nano diamond alkene. The outer surface of the inner pipe body is sequentially provided with an infrared reflective layer, an absorption layer and a light transmittance protective layer from inside to outside. The invention also provides a manufacturing method of the solar water heater heat collection pipe. The manufacturing method comprises the following steps that the inner pipe body is manufactured; the infrared reflective layer is deposited; the absorption layer is coated; and the light transmittance protective layer is deposited, so that the solar water heater heat collection pipe is obtained. According to the solar water heater heat collection pipe and manufacturing method of the solar water heater heat collection pipe, the sleeve made from the nano diamond alkene serves as the inner pipe body of the heat collection pipe, and the heat conductivity of the nano diamond alkene is very high and reaches up to 120 W.K<-1>.cm<-1>, so that rapid heat conduction is achieved, energy sources are saved, and the using efficiency is improved.
