Embodiment 1
[0023] A preparation method of a non-woven rabbit fleece thermal insulation material, comprising the steps of:
[0024] (1) Rabbit short fleece is selected as the main raw material, and a certain proportion of medium-length hollow three-dimensional curly polyester and wool short fleece fibers are mixed. The specific ratio is: rabbit short fleece: 60%; cashmere offal: 20%; hollow polyester: 20%.
[0025] First, the antistatic oil is sprayed on the rabbit fleece by spraying. After 20 hours, it is mixed with wool fleece and hollow curly polyester fiber. It is processed into a thermal insulation material through a dry-laid needle-punched reinforcement non-woven process. The thickness is 6mm. The length of the short fleece is 2.5-3.5cm
[0026] (2) The production process is: Rabbit short fleece, cashmere scraps, hollow polyester fiber ingredients - mixing - opening - mechanical carding - net laying - acupuncture - rolling.
[0027] (3) The main process of acupuncture is: input s...

[0037] A preparation method of a non-woven rabbit fleece thermal insulation material, comprising the steps of:
[0038] (1) Rabbit short fleece is selected as the main raw material, and a certain proportion of medium-length hollow three-dimensional curly polyester and wool short fleece fibers are mixed. The specific ratio is: rabbit short fleece: 70%; cashmere offal: 10%; hollow polyester: 20%.
[0039] First, the antistatic oil is sprayed on the rabbit fleece by spraying. After 22 hours, it is mixed with wool fleece and hollow curly polyester fiber. It is processed into a thermal insulation material through a dry-laid needle-punched reinforcement non-woven process. The thickness is 6mm.
[0040] (2) The production process is: Rabbit short fleece, cashmere scraps, hollow polyester fiber ingredients - mixing - opening - mechanical carding - net laying - acupuncture - rolling.
[0041] (3) The main process of acupuncture is: input speed: 2.92m / min, acupuncture density: 150-160...
