2results about How to "Lower contact temperature" patented technology

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 utility model relates to the field of tables and benches, and in particular to a tea-brewing table and bench, comprising a table body including a tabletop and a first support frame located below the tabletop. A hole is provided at the center of the tabletop. The first support frame is a ring-shaped support frame with a vertical projected area smaller than the projected area of ​​the tabletop. A functional compartment, installed in the hole, is either a storage basket or a stove body. The stove body includes the functional compartment and an induction cooker or charcoal stove that can rotate 180° around a horizontal axis, installed inside the functional compartment. Through the synergistic effect of the hourglass-shaped structure of the ring support frame (a combination of first rings with diameters increasing and decreasing from bottom to top) and the rotating stove body mechanism (a functional compartment with a limiting groove and a T-shaped block mounting bracket), structural stability is ensured while providing legroom that conforms to the user's sitting posture curve. The largest diameter ring is precisely positioned within the ankle height range.
