specific Embodiment 1
[0038] Combine below Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a thermal insulation canvas and its processing technology, including a waterproof layer 1 and a thermal insulation layer 2, the thermal insulation layer 2 is arranged in multiple layers, and the thermal insulation layer 2 is arranged between the upper and lower waterproof layers 1, The insulation layer 2 and the waterproof layer 1 are fixed by ultrasonic welding.
[0039] Specifically, ultrasonic welding points 3 are provided in the array of welded and fixed positions of the insulation layer 2 and the waterproof layer 1 .
[0040] Specifically, the density interval of the ultrasonic welding points 3 is not greater than 15mm.
[0041] Specifically, the waterproof layer 1 is made of composite flame-retardant polyester fabric, and the insulation layer 2 is made of high-molecular thermal insulation and moisture resistance cotton.
[0042] Specifically, the polymer thermal insula...
specific Embodiment 2
[0044] A processing technology for thermal insulation canvas, comprising the steps of:
[0045] Sp1: Spinning of insulation layer 2, blending nomex fiber with cotton fiber;
[0046] Sp1-1: Opening and mixing of raw materials, nomex fiber and cotton fiber contain less impurities, and three opening and mixing can be directly used to loosen and mix the two fiber raw materials as much as possible to form a lap or loose Cotton, and need to prevent fiber damage;
[0047]Sp1-2: Carding, after opening and cleaning, the fibers in the laps or loose cotton are mostly in the state of loose cotton blocks and cotton bundles, containing some small, highly adhesive fibrous impurities, using roller combing The cotton machine combs the small cotton bundles into a single fiber state by means of the movement of the needle surface, so that the fibers are straightened in parallel and made into a uniform sliver;
[0048] Sp1-3: Draw frame and roving, feed 6-8 cotton slivers together into the draw ...

Abstract
The invention discloses heat preservation canvas and a processing technology thereof, and belongs to the technical field of heat preservation canvas, the heat preservation canvas comprises waterproof layers and heat preservation layers, the number of the heat preservation layers is multiple, the heat preservation layers are arranged between the upper waterproof layer and the lower waterproof layer, and the heat preservation layers and the waterproof layers are fixed through ultrasonic welding. In the production process of the canvas, the heat preservation canvas is formed through opening and mixing of raw materials of the heat preservation layer, cotton carding, drawing, roving, spinning, spinning of the waterproof layer and ultrasonic welding of the heat preservation layer and the waterproof layer in sequence. According to the heat preservation canvas, the heat preservation layer and the waterproof layer are adopted to replace cotton, chemical fibers and other short fiber materials in the traditional process, the excellent windproof and cold-resistant capacity can be achieved without heavy and rough thick raw materials, meanwhile, the smooth waterproof layer is good in comfort degree, and the heat preservation canvas has good strength. The heat preservation layer made of high-molecular thermal insulation moisture-resistant cotton formed by blending nomex fibers and cotton fibers has excellent flame retardance and heat preservation performance.
Description
technical field [0001] The invention relates to the technical field of thermal insulation canvas, in particular to a thermal insulation canvas and its processing technology. Background technique [0002] Canvas is a thicker cotton or linen fabric, named after it was originally used for sails. Generally, plain weave is used, a small amount of twill weave is used, and multi-strand yarns are used for warp and weft yarns. Canvas is usually divided into two categories: coarse canvas and fine canvas. Fine canvas is used in the production of clothing and supplies, while coarse canvas, also known as tarpaulin, has good waterproof performance, and its biggest feature is that it is durable and used for large-scale shelter and heat preservation. And this product is mostly used for heat preservation and shielding treatment of air conditioners. [0003] Traditional canvas basically uses cotton, chemical fiber and other short fibers as raw materials, and produces canvas through spinnin...
