NOVELTY - The plate type solar heat insulation heat preservation polyester cotton, comprises a heat preservation cotton layer (1), a cotton layer (2), a hot melt fiber net adhesive layer (3), and an aluminum foil layer (4). The polyester cotton has a four-layer compound structure. The heat preservation cotton layer has vertical or flat laying structure. The strength of the cotton core layer has a flat lapping structure. The heat preservation polyester cotton is processed by taking hot-melting fiber and functional fiber in accordance with a weight ratio of 15:85.    USE - Used as a plate type solar heat insulation heat preservation polyester cotton.    ADVANTAGE - The plate type solar heat insulation heat preservation polyester cotton exhibits good fire-proof properties, high life quality, increased aging resistance and corrosion resistance, and excellent performance, can be easily processed, and does not pollute the environment.    DETAILED DESCRIPTION - The plate type solar heat insulation heat preservation polyester cotton, comprises a heat preservation cotton layer (1), a cotton layer (2), a hot melt fiber net adhesive layer (3), and an aluminum foil layer (4). The polyester cotton has a four-layer compound structure. The heat preservation cotton layer has vertical or flat laying structure. The strength of the cotton core layer has a flat lapping structure. The heat preservation polyester cotton is processed by taking hot-melting fiber and functional fiber in accordance with a weight ratio of 15:85 and then carding the fibers by a unit of vertical or flat laying paving square of uniform thickness of 300-1500 G to prepare heat preservation cotton between the insulation board and flocculation cotton wheel, taking hot melting fiber and functional fiber in accordance with a weight ratio of 45:55, performing flat laying after carding the paving method of square with uniform thickness of 90-400G to prepare strong flocculating cotton wheel, performing heat preservation of cotton wadding tire to the strong flocculating cotton tire to prepare the heat preservation cotton layer and cotton layer, taking 100% of direct hot-melt fiber loosening comb into per square meter gram weight of 10-30 G ultra-thin fiber net as adhesive layer to prepare hot melt fiber net adhesive layer, preparing the high performance fiber composite cotton by preparing the ultra-thin fiber net paving strong upper wadding layer as the adhesive with aluminum foil paper at the same time into the second section oven using double-area hot high temperature heat storage heating method, and cutting the strong cotton layer to form the high-performance fiber composite cotton. The function fiber is copolymer mixing method with a permanent resistant inflaming retarding functional polyester hollow colored fiber. The hot melt fiber has a high melting point of 190 degrees C bi-component sheath-core colored hollow fiber.
