Example Embodiment

[0018] The technical scheme of the present invention will be further elaborated below in conjunction with the drawings and specific embodiments:

[0019] Such as figure 1 with figure 2 Shown: the present invention provides a reinforced, heat-insulating three-dimensional fabric, comprising an upper surface layer 1, a lower surface layer 2, and an intermediate layer 3 arranged between the upper and lower surface layers, the intermediate layer 3 includes spacer filaments 31 and a silica aerogel 32 doped with whiskers 321 or / and reinforced short fibers 322, the silica aerogel 32 is uniformly filled in several spaces formed by the arrangement of spacer filaments 31; The spacer wire 31 is W-shaped (such as figure 1 Shown) or X-shaped (such as figure 2 Shown) Arrangement structure.

[0020] As a preferred solution, a heat reflective coating 4 is provided on the upper surface layer or / and the lower surface layer to further reduce heat radiation and surface temperature.

[0021] As a pre...

Abstract

Disclosed reinforced heat-insulation three-dimensional fabric comprises an upper surface layer, a lower surface layer and an intermediate layer arranged between the upper surface layer and the lower surface layer, wherein the intermediate layer comprises spacing fibers and silica aerogel dopped with whisker or/and reinforced short fiber, and multiple intervals formed by arrange of the spacing fibers are filled with the silica aerogel. The three-dimensional fabric provided by the invention not only has good fire resistance, heat resistance and heat insulation performance, but also has good compressive strength, bending strength and tensile strength, is capable of satisfying the application requirements in the fields of fire fighting, industrial heat insulation and the like, and has practicality.

Description

technical field [0001] The invention relates to a three-dimensional fabric, in particular to a reinforced and heat-insulating three-dimensional fabric. Background technique [0002] Three-dimensional fabric, also known as spacer fabric, refers to a double-layer fabric structure, which is composed of upper and lower fabrics and spacer yarns, and the middle of the fabric is connected by spacer yarns of different stiffness. Spacer yarns usually use polyester or nylon filaments with high bending stiffness, so that the two surface layers can be propped up and separated to form a middle layer with a certain thickness that stores more air. The structural characteristics of the spacer fabric and the characteristics of the spacer yarn endow the spacer fabric with a stable structure and unique physical properties, which can be widely used in many fields such as clothing, decoration and industry. [0003] In a strong heat radiation environment, personal protective equipment and occasi...
