It is difficult to meet the needs of multi-functional comfortable fabric through the single functional fibers on the market. The aim of this work was to develop a kind of summer comfortable woven fabric with coolness through the combination of different functional fibers. Blended yarn of bamboo and polyester with grooves was chosen as the warp yarn, which was responsible for moisture absorption and transportation. Nylon filament with a cross-section and fine-denier polyester filament was chosen to twist reversely as a composite weft yarn to provide the coolness function and moisture conduction for fabric. As a comparative weft yarn, polyethylene was chosen as another type of weft yarn. Twelve samples were prepared containing three structures. The effects of fabric structure, weft yarn composition and fineness on the coolness and thermal-wet comfort were evaluated and investigated, including thermal-physiological comfort properties, moisture management properties, the wicking effect and the drying performance. The result showed that the weave structure, weft yarn composition and fineness had a significant influence on the coolness and thermal-wet comfort properties. Fabric woven with plain weave structure contributed to heat dissipation and dynamic coolness. The float yarn in the 2/1 twill and mesh structure was beneficial to promote water transportation vertically. The results also suggested that polyethylene yarn was preferred for coolness fabric, but the liquid moisture management and drying performance of polyethylene fabric should be further improved.

The Xishadegai Mo deposit is a medium‐sized deposit located in the northern margin of the North China Craton. The Mo mineralization is structurally controlled, and spatially and temporally related to the Xishadegai felsic intrusive rocks. Ore bodies mainly occur as quartz veins/veinlets in altered granitic rocks associated with potassic, phyllic, argillic, and fluorite alterations. The ore‐forming process can be divided into 3 stages: Stage I K‐feldspar‐quartz ± molybdenite, Stage II quartz‐pyrite‐molybdenite‐muscovite ± fluorite, and Stage III quartz‐fluorite ± muscovite. Four types of fluid inclusions were distinguished in smoky grey and dark grey quartz of the main‐ore stage (II), including two‐phase aqueous inclusions, CO2‐H2O inclusions, daughter mineral‐bearing multiphase inclusions, and minor vapour aqueous inclusions. The fluid inclusions in smoky grey and dark grey quartz are homogenized at temperatures of 195–350 °C and 191–291 °C, respectively, with calculated salinities of 3.9–11.1% NaCleq and 31.5–33.0% NaCleq, respectively. The ore‐forming fluids belong to a H2O‐CO2‐NaCl system characterized by abundant CO2, moderate to high temperature, and low to high salinity. The δ18OH2O and δD values of ore‐stage quartz vary from −0.2‰ to 0.9‰ and from −120‰ to −104‰, respectively, indicating that the ore‐forming fluids were evolved from magmatic water and gradually mixed with significant amounts of meteoric water. Sulphur and lead isotopic compositions indicate that the ore materials were mainly derived from magmatic sources. Zircon LA‐ICP‐MS U–Pb dating on the mineralized porphyritic moyite yielded a weighted mean age of 235.1 ± 2.0 Ma, corresponding to the Triassic postcollisional setting following the closure of the Paleo‐Asian Ocean between the Siberian Plate and the North China Craton. The εHf(t) values and TDM2 ages range from −15.0 to −12.8 and from 2.2 to 2.1 Ga, respectively, suggesting that the Xishadegai granite was mainly generated by melting of Paleoproterozoic crustal components. Collectively, evidence from geology, fluid inclusion, H‐O‐S‐Pb isotopes, and geochronology suggests that the Xishadegai deposit could be classified as a magmatic–hydrothermal vein Mo deposit. Phase separation (immiscibility and boiling) was the most likely mechanism for ore deposition.
