A cooling, UV-resistant jacquard knitted fabric and garment

Abstract

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.

Description

Technical Field

[0001] This utility model relates to the field of knitting weft knitting, and in particular to a cool-feeling UV-resistant jacquard knitted fabric and garment. Background Technology

[0002] Weft-knitted fabrics are made from yarns such as polyester, nylon, cotton, wool, and elastic fibers. They are fabrics formed by using knitting needles on various weft knitting machines to bend the yarns into loops and interlock them in the horizontal direction.

[0003] With advancements in textile technology and the development of new yarn materials, the market demand for fabrics with differentiated functionalities is growing. Currently, most cooling and UV-resistant fabrics are made from conventional polyester / nylon fabrics through finishing processes with auxiliaries. However, the cooling and UV-resistant agents in these fabrics are lost due to friction from wearing and washing, leading to a rapid decline in their functional effects and making it difficult to meet the requirements for long-term use.

[0004] Therefore, it is necessary to provide a cooling and UV-resistant jacquard knitted fabric that enables products to have long-lasting UV protection and cooling effects. Utility Model Content
