Description

Technical Field

[0001] The utility model relates to an air layer wool double-faced fabric, belonging to the technical field of textile fabrics. Background Art

[0002] As people's living standards improve, the requirements for clothing performance in all aspects are getting higher and higher. In terms of thermal insulation, it is required to have good thermal insulation properties, while also being thin and light. Double-faced woolen fabric is a fabric woven from two pieces of fabric with different textures. Double-faced woolen fabric is usually suitable for winter outerwear due to its thicker fabric. Existing double-faced woolen fabric is usually formed by bonding two layers of fabric together, and its thermal insulation fabric depends on the thickness of the double-layer fabric. However, compared with the cold winter in the north or plateau areas, the thermal insulation effect will be relatively weak. How to improve the thermal insulation effect of double-faced woolen fabric in the cold winter has become a problem to be solved. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 and Figure 2 The present embodiment is described in detail. The present embodiment involves an air layer wool double-faced fabric, comprising a surface layer 1, an inner layer 2, and a weft yarn 3 for connecting the surface layer 1 and the inner layer 2; an air layer 4 is formed between the surface layer 1 and the inner layer 2.

[0019] The surface layer 1 is formed by interweaving the surface warp yarn and the surface weft yarn according to the warp satin weave, the surface warp yarn includes a core yarn and a wrapping yarn wrapped around the outside of the core yarn, the wrapping yarn is a caterpillar cross-section polyester filament, the cross section of the caterpillar cross-section polyester filament includes a fiber body 11 in the shape of a straight line and raised portions 12 symmetrically arranged on both sides of the fiber body 11; the side of the surface layer 1 away from the inner layer 2 has a caterpillar cross-section polyester filament formed by raising the warp to form a fluff layer 5. The fiber body 11 is in the shape of a straight line, and the raised portions 12 arranged on both sides make the fluff in the fluff layer 5 have good uprightness. After being touched or in contact with other objects, the fluff in the fluff layer 5 can stand up quickly.

[0020] Furthermore, the core yarn includes aerogel fiber yarn twisted in parallel. The surface weft yarn includes woolen spun yarn, and a woolen worsted yarn is wound around the outside of the woolen spun yarn. The surface warp yarn and the surface weft yarn are interwoven in a warp satin weave, which is characterized by one side of the warp float long line being located on the outside. The warp satin weave is a five-piece three-fly warp satin weave. The woolen spun yarn used in the surface weft yarn has a fluffy structure and has a good warming effect.

[0021] The inner layer 2 is interwoven with inner layer warp yarn and inner layer weft yarn, wherein the inner layer warp yarn is woolen worsted yarn. The inner layer weft yarn includes woolen spun yarn, and a woolen worsted yarn is wound around the outer side of the woolen spun yarn. The woolen spun yarn used in the inner layer weft yarn has a fluffy structure and has a good warming effect.

[0022] Furthermore, the binding weft yarn is hollow polyester filament, which can also improve the warmth-keeping effect.

[0023] Embodiment 2

[0024] The utility model relates to an air layer wool double-faced fabric, which is different from the first embodiment in that the core yarn also includes hot-melt filaments twisted with antibacterial polyester filaments. The hot-melt filaments are specifically a core-skin structure, with a core layer of high-melting-point PET and a skin layer of low-melting-point PET. The low-melting-point PET can melt at a lower temperature and can bond with the corresponding fibers, thereby reducing the shedding of the fluff layer 5.

[0025] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
