Furthermore, the weaving layers are all woven by hollow yarns. The hollow yarns greatly reduce the weight of the fabric with the same thickness and contribute to improving the bulkiness of the fabric.

Furthermore, the inner layer knitted layer and the surface layer knitted layer are both woven by profiled fibers, the profiled fibers are formed by bundling a plurality of fiber monofilaments in parallel, and the cross sections of the fiber monofilaments are Y-shaped. Due to the structural design of the profiled fibers, the surfaces of the inner layer knitted layer and the surface layer knitted layer are more fluffy, and the heat retention property is improved.

Furthermore, the height of the bump structure is 0.1-0.2 mm.

Furthermore, the inner layer knitted layer and the surface layer knitted layer are both plain weave.

Further, the braided layer is two or three layers.

Furthermore, the polypropylene warm-keeping knitted fabric further comprises a printing layer, and the printing layer is located on the surface of one side, far away from the woven layer, of the surface knitted layer. Due to the design of the printing layer, the functionality of the fabric is improved, and the fabric is more attractive.

Further, the lining knitting layer, the surface knitting layer and the knitting layer are connected through long floating threads.

Furthermore, the surface of one side of the knitting layer of the inner layer, which is far away from the knitting layer, is provided with a soft velvet layer. Due to the arrangement of the soft velvet layer, the comfort and the heat retention of the fabric are improved.

Further, the heat generating fiber is far infrared fiber. The far infrared fiber can absorb external heat and store the heat and then radiate the heat to the human body.

Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage:

1. the utility model discloses a set up the multilayer weaving layer, and along being close to the direction of keeping away from the nexine knitting layer, the density of the bump structure on polypropylene fibre layer increases gradually in each weaving layer, and on the thickness direction along the surface fabric, the bump structure in the weaving layer forms multi-level structure like this, because the bump structure density on surface fabric top layer is higher, outside consequently the heat in the skin can slowly discharge, makes the cold-proof effect of fabrics performance.

2. The combination of the polypropylene fiber layer and the heating layer enables the fabric to combine the advantages of the polypropylene fiber and the heating fiber. Especially, the heating effect of the heating fiber is utilized, and the good heat preservation effect is achieved by means of heat radiation.

3. The design of the convex point structure in the weaving layer makes the space that holds the air form in the weaving layer to pin the air, reduce body surface air and external heat exchange efficiency, thereby increase its warmth retention property.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Examples

Referring to the attached drawings, the polypropylene warm-keeping knitted fabric in the preferred embodiment of the present invention includes an inner knitted layer 4 contacting with the human body and a surface knitted layer 2 contacting with the external environment, and a three-layer knitted layer 3 is provided between the inner knitted layer 4 and the surface knitted layer 2. The inner layer knitting layer 4, the surface layer knitting layer 2 and the knitting layer 3 are connected through long floating threads.

The inner layer knitting layer 4 and the surface layer knitting layer 2 are both plain weave. The inner layer knitting layer 4 and the surface layer knitting layer 2 are both woven by profiled fibers, the profiled fibers are formed by parallelly bundling a plurality of fiber monofilaments 20, and the cross sections of the fiber monofilaments 20 are Y-shaped. Due to the structural design of the profiled fibers, the surfaces of the inner layer knitted layer 4 and the surface layer knitted layer 2 are more fluffy, and the heat retention property is improved.
