2results about How to "Cool feeling" patented technology

This utility model relates to a cooling and UV-resistant jacquard knitted fabric and garment. The front of the fabric consists of alternating concave and convex stripes, each made of 40D / 24F polyethylene nylon core yarn and 20-50D spandex. The knitting pattern is four loops per cycle, with the first four loops using the polyethylene nylon core yarn and spandex. The concave stripes are formed by loops knitted by the first needle of each of the first four loops. The convex stripes are formed by loops knitted by the second and third needles of the first and second loops, respectively, followed by float knitting, and by the second and third needles of the third and fourth loops, respectively, followed by float knitting and loop knitting. Through the combination and loop-forming method of the functional yarns—polyethylene nylon core yarn and high-elastic spandex—the fabric achieves a cooling sensation and highly effective UV blocking across the entire wavelength range, while also possessing breathability, high elasticity, and comfort.

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.
