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.
