Embodiment 1

[0020] Example 1: see figure 1 As shown, a light-weight thermal insulation fabric includes an outer dense thermal insulation layer 10 sewn into one and located on the surface, a hollow thermal insulation layer 20 located in the middle, and an inner dense thermal insulation layer 30 located on the inner layer, wherein the outer dense thermal insulation layer The raw material of layer 10 is the superfine fiber-wool blended yarn prepared by 80% superfine fiber with a public count of 1500N and 20% wool fiber through the blending process, and the superfine fiber-wool blended yarn is used as Warp yarns and weft yarns are manufactured to obtain an outer dense thermal insulation layer 10, which ensures the thermal resistance of the fabric and is used to improve the cold resistance of the surface of the fabric. Yarns are manufactured as warp yarns and weft yarns to obtain a hollow insulation layer 20. Since the hollow fiber has a thin tubular cavity in the axial direction, the hollowne...

Embodiment 2

[0021] Embodiment 2: the technical scheme of this embodiment 2 is the same as that of embodiment 1, the difference is that: this embodiment 2 proposes a kind of light-weight thermal insulation fabric, and the outer surface of the outer dense thermal insulation layer is sewn waterproof fabric, and this embodiment 1 makes The lightweight thermal fabric has a grammage of 245 grams per square meter.

Embodiment 3

[0022] Embodiment 3: The technical solution of this embodiment 3 is the same as that of embodiment 1, the difference is that: this embodiment 3 proposes a light-weight warm-keeping fabric, and the hollow fiber yarn adopts 90% hollow fiber and 10% phase change fiber blending When the external temperature rises, the phase change fiber absorbs heat energy and melts to store heat in the hollow insulation layer, and when the external temperature decreases, it releases heat and crystallizes to release heat to the hollow insulation layer; specifically, in this In an embodiment, the phase-change fiber adopts Comfort Temp constant-temperature phase-change fiber sold by Swiss Scholler Company.

Abstract

The invention discloses a light warm-keeping fabric. The light warm-keeping fabric comprises an outer compact heat-preservation layer and located on the surface layer, a hollow heat-preservation layerlocated in the middle, and an inner compact heat-preservation layer located on the inner layer, wherein the outer compact heat-preservation layer, the hollow heat-preservation layer and the inner compact heat-preservation layer are sewn into a whole; ultrafine fiber-wool blended yarn prepared from ultrafine fibers and wool fibers through a blending process are adopted as raw materials of the outer compact heat-preservation layer to guarantee heat resistance of the fabric and improve the cold-proof property of the surface of the fabric, wherein the metric count range of the ultrafine fiber-wool blended yarn is not lower than 1000 N; hollow fiber yarn woven by hollow fibers is adopted as the hollow heat-preservation layer, and a cavity for avoiding air convection is formed in the middle ofthe fabric; and an ultrafine non-woven fabric prepared from ultrafine fibers through a non-weaving process is adopted as the inner compact heat-preservation layer to quickly adsorb heat-preservation air in an idle state, wherein the metric count range of the ultrafine non-woven fabric is not lower than 1000 N. The heat-preservation property of the fabric is improved through a combination of composite functional layer structures, meanwhile the raw materials are portable, and bloating of the fabric is further avoided.

Description

technical field [0001] The invention belongs to the field of knitted fabrics, and in particular relates to a lightweight warm-keeping fabric. Background technique [0002] With the rapid development of the domestic economy, people's living standards have been significantly improved, and there is a higher level of demand for clothing and home textiles. Specifically, conventional warm and cold-proof clothing mostly uses heavy and bloated warm-keeping flocs, which lack aesthetic feeling, and as people pay more attention to aesthetics, fabrics with light weight and warm-keeping properties have become the main technical trend of the fabric industry. [0003] Seeking both warm and lightweight fabrics has become the main research and development direction of the textile fabric industry. In recent years, more technical solutions have been proposed. For example, the invention patent with the publication number CN109989172A discloses a warp-knitted light-weight thermal shirt fabric, a...
