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...

Embodiment 2

[0030] A preparation method of a non-woven rabbit fleece thermal insulation material, comprising the steps of:

[0031] (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 in. The specific ratio is: rabbit short fleece: 80%; cashmere offal: 10%; hollow polyester: 10%.

[0032] First, the antistatic oil is sprayed on the rabbit fleece by spraying. After 24 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.

[0033] (2) The production process is: Rabbit short fleece, cashmere scraps, hollow polyester fiber ingredients - mixing - opening - mechanical carding - net laying - acupuncture - rolling.

[0034] (3) The main process of acupuncture is: input speed: 2.81m / min, acupuncture density: 150-...

Embodiment 3

[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...

Abstract

The invention belongs to the fields of agricultural industry, light industry, textile industry and the like and discloses a non-woven rabbit linter thermal insulation material and a producing method thereof. The non-woven rabbit linter thermal insulation material comprises the following components in percentage by weight: 60-80% of rabbit linters, 10-20% of cashmere wastes and 10-20% of hollow polyesters. The non-woven rabbit linter thermal insulation material disclosed by the invention has the advantages of good heat insulation, light and thin product, good air permeability and good integrity; the defect that a plurality of traditional heat insulation materials (such as lint and downs) are hard to shape is overcome; moreover, the non-woven rabbit linter thermal insulation material can be also cut into various desired shapes and is extremely convenient. The non-woven rabbit linter thermal insulation material disclosed by the invention has the advantages of simple production process, low production cost and easiness for industrial production and promotion.

Description

technical field [0001] The invention belongs to the fields of agriculture, light industry, textile industry and others, and in particular relates to a non-woven rabbit short-pile thermal insulation material and a production method thereof. Background technique [0002] my country is rich in rabbit fur resources, and the production areas are very vast, concentrated in Zhejiang, Shandong, Jiangsu, Anhui, Henan, Shanghai and other places. The annual output ranks first in the world, and the annual output of Angora rabbit fur accounts for 90% of the world's total output. , is 20% of domestic wool. High-quality rabbit down can be spun and weaved. The utilization rate of secondary rabbit down is very low. Rabbit short down and spinning scraps are all discarded as waste, resulting in a great waste of raw material resources. [0003] The research and development of this product is a reasonable development of rabbit short fleece and leftover resources. The non-woven thermal insulation...
