Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1 and 2, the utility model provides a fire-retardant type alkali-free glass fiber cloth, including: core layer 1, glass fiber layer 2, fire-retardant layer 3 and inoxidizing coating 4.
The core layer 1 includes two nonwoven fabric layers 11, a plurality of support tubes 12, and a tie line 13.
The two non-woven fabric layers 11 are oppositely arranged.
A plurality of support tubes 12 are disposed between the two nonwoven fabric layers 11. The support tubes 12 are arranged in a quincunx pattern. The support tube 12 is woven from elastane. The specific support tube can be formed by weaving polyethylene or polypropylene fibers. Both ends of the support tube 12 are respectively welded to opposite sides of the two nonwoven fabric layers 11. A tie line 13 is connected between the support tube 12 and the adjacent support tube 12.
