Description

Technical Field

[0001] The utility model relates to a thermal insulation composite knitted fabric. Background Art

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlacing them with knitting needles. They are divided into warp knitted fabrics and weft knitted fabrics. Knitted fabrics have the characteristics of soft texture, moisture absorption and breathability, perspiration and warmth retention, and most of them have excellent elasticity and extensibility. Compared with woven fabrics, they have high production and are suitable for small batch production. Knitted clothing is comfortable to wear, fits the body, has no sense of tightness, and can fully reflect the curves of the human body. Knitted fabrics have a soft texture. In addition to good wrinkle resistance and breathability, they also have greater extensibility and elasticity, making them suitable for underwear, tights and sportswear. After changing the structure and improving dimensional stability, knitted fabrics can also be used as outerwear. Knitted fabrics can be woven into grey cloth first, and then cut and sewn into various knitted products; they can also be directly woven into fully formed or partially formed products, such as socks, gloves, etc. Knitted fabrics are used for clothing, daily life and decoration such as underwear, outerwear, socks, gloves, hats, bed sheets, bedspreads, curtains, mosquito nets, carpets, lace, etc., and are also widely used in the fields of industry, agriculture, and medical health. However, the existing knitted fabrics are generally single-layered and are made of yarns, so the existing knitted fabrics have poor thermal insulation performance during actual use.
