AI Technical Summary
Existing knitted fabrics tend to shed fibers during washing after the addition of a pile layer, resulting in a decrease in warmth retention.
Design a composite knitted fabric, which uses a first fabric layer and a second fabric layer. The first and second pile strips are bonded to the fabric layers and arranged opposite each other to form an air gap to prevent the convection of air inside and outside. The structural strength is enhanced by connecting them with hot melt adhesive. The pile strips are placed inside the fabric layers to avoid direct friction.
It improves the warmth and durability of knitted fabrics, reduces shedding, and maintains the fluffiness and warmth of the pile.

TECHNICAL FIELD
[0001] The utility model relates to textile technology field, concretely is a kind of composite knitted fabric. BACKGROUND
[0002] With the progress of science and technology, the development of society, China's textile industry has been rapid development, with the rapid development of fabric, more and more different kinds of fabric come into being.
[0003] Knitted fabric is formed by bending yarn into loops and interlocking each other by using knitting needle, and it is divided into warp-knitted fabric and weft-knitted fabric, which is widely used in many fabrics. Knitted fabric has soft texture, breathable and cool characteristics, so it is often made into underwear, tights and sportswear, etc., and is welcomed and loved by consumers.
[0004] At present, the existing knitted fabric is usually breathable and cool, so it has poor warmth retention. In order to improve the warmth retention, a layer of fluff layer is usually arranged on the knitted fabric. The fluff layer is soft and fluffy, and has good heat accumulation and warmth retention, so as to improve the warmth retention of the knitted fabric. However, since the fluff layer is arranged on the surface of the knitted fabric, it will shed during washing, so that the fluff becomes sparse, which can easily lead to the decrease of the warmth retention of the knitted fabric.

[0007] As a further setting of the utility model, gap is formed between first fluff strip and second fluff strip.
[0008] As a further setting of the utility model, the first cloth layer and the second cloth layer are both made of several elastic yarn weft knitting.
[0009] As a further setting of the utility model, the elastic yarn includes wire core and anti-abrasion yarn spirally wound outside the wire core, and the anti-abrasion yarn is twisted by several polyamide fibers.
[0010] As a further setting of the utility model, the core includes inner core and covering yarn spirally wound on the outer side of the inner core, the inner core is formed by first winding and second winding spirally interlaced, the first winding is formed by twisting a plurality of spandex fibers, and the second winding is formed by twisting a plurality of polyester fibers.
[0011] As a further setting of the utility model, the first connecting section and the second connecting section are bonded together by hot melt adhesive.
[0012] Compared with the prior art, the utility model has the beneficial effects that:
[0013] The utility model discloses a first fluff strip and second fluff strip are set up, and there is a larger gap between the fluff on the first fluff strip and the second fluff strip, can store a large amount of static air, thereby forming the air interlayer between the first protruding section and the second protruding section, effectively prevent the convection of the inner and outer air, thereby forming a plurality of static air layers in the knitted fabric, reducing the heat loss, making the knitted fabric have better warm-keeping and heat-storing effect, and since the first fluff strip and the second fluff strip are arranged in the knitted fabric and are not directly exposed to the outside, the knitted fabric is not directly subjected to friction when washing, thereby reducing the hair loss, and even if the hair loss still remains in the knitted fabric, thereby keeping the warmth of the knitted fabric.
