This invention belongs to the field of functional textile materials and provides a cooling and antibacterial polyester fabric and its preparation method. The invention employs a melt-blended spinning design of a thermally conductive antibacterial core-shell masterbatch and a polyester matrix. The masterbatch uses a zinc oxide submicron rod-shaped inorganic core as its core, coated with a silane coupling layer and a quaternized copolyester shell. During fiber drafting, the one-dimensional zinc oxide rods are aligned axially, significantly improving the longitudinal thermal conductivity of the fiber and enhancing the instantaneous cooling sensation upon contact. Simultaneously, the quaternized copolyester shell exhibits good compatibility with the polyester matrix, constructing a dense, wash-resistant, and antibacterial network. This achieves synergistic optimization of high-strength, fine-denier spinnability with high-filler thermal conductivity, durable antibacterial properties after 50 machine washes with a soft and comfortable feel, and high functionalization efficiency with low migration safety. It resolves the technical contradictions in existing polyester fabrics regarding thermal conductivity and cooling sensation versus antibacterial durability, functionality versus safety, and processability versus comfort, and has broad application value in areas such as intimate apparel and bedding.

This invention belongs to the field of polymer composite materials technology, and provides a low-odor flame-retardant polypropylene composite material and its preparation method. The preparation of this composite material includes the following steps: mixing polypropylene, a flame retardant, a lubricant, an antioxidant, and a defoamer to obtain a premix; mixing the premix and an odor inhibitor to obtain an intermediate product; and melt-extruding and granulating the intermediate product to obtain the low-odor flame-retardant polypropylene composite material. This invention eliminates odorous volatile substances generated during the preparation of the premix by heating, defoaming with a defoamer, and vacuuming. Furthermore, after eliminating the odorous volatile substances, an odor inhibitor is added to further suppress the generation of unpleasant odors. The resulting polypropylene composite material has advantages such as low odor and high flame retardancy.

A heat exchanger (1) includes: a tube (10) through which a first fluid flows; and fins (20) which are formed by bending the plate-shaped members and which promote heat exchange between the first fluid and the second fluid flowing outside the tubes. The outer surface (21) of the fin has a first region (21A) and a second region (21B) having higher hydrophilicity than the first region. A groove (22) for improving the hydrophilicity of the outer surface is formed in the second region. The second region is disposed adjacent to a region (12A) of a portion of a joining portion (12) between the tube and the fin.

The utility model provides a three-section type shoe drying deodorization pen. The three-section type shoe drying deodorization pen comprises a heating air duct module, a turning hose module and a main switch module. The heating air duct modules are arranged at the two ends of the device correspondingly and each comprise an ultraviolet lamp strip, a motor, fan blades and a thermal fuse heating device. The turning hose modules are respectively arranged between the heating air duct modules and comprise turning hoses and wire hoses; the main switch module is arranged between the turning hose modules and comprises a charging port, a switch and a battery. According to the shoe dryer, shoes can be heated and dried through the thermofuses and the fan blades under the driving of the motor, and the heating efficiency is high; meanwhile, the ultraviolet lamp strip is driven to specially sterilize the front end of the shoe, and organic gas is quickly oxidized and decomposed to achieve the effect of removing peculiar smell; due to the three-section type bendable design, compared with a shoe dryer in the prior art, the three-section type shoe drying deodorization pen is efficient, small and portable.
