Embodiment Construction
[0014] Non-limiting examples of the present invention are as follows:
[0015] A kind of anti-moth down composite thermal insulation material is prepared from the following component raw materials with weight (kg):
[0016] Duck down 35, jute fiber 12, polylactic acid composite fiber 15, polyvinyl alcohol fiber 8, sodium carboxymethyl cellulose 0.4, sodium laurate 0.15, tea saponin 0.15, palm oil 1.5, nano silicon dioxide 0.15, water 12;
[0017] The polylactic acid composite fiber is prepared from the following raw materials in parts by weight: polylactic acid 45, shell powder 5, glycerin 6, silane coupling agent KH-5500.4; the preparation method of the polylactic acid composite fiber is to combine shell powder with After mixing the silane coupling agent KH-550, treat it at 100°C for 1 hour, mix it with other raw materials evenly after cooling, place it at room temperature for 3 hours, use a twin-screw extruder to make materials at 160-180°C, and then spin it by conventional ...

The invention discloses a moth-proof down composite thermal material. The moth-proof down composite thermal material is prepared from the following materials in part by weight: 30 to 40 parts of duck down, 10 to 15 parts of jute fiber, 10 to 20 parts of polylactic acid composite fiber, 5 to 10 parts of polyvinyl alcohol fiber, 0.3 to 0.5 parts of sodium carboxymethyl cellulose, 0.1 to 0.2 parts of sodium laurate, 0.1 to 0.2 parts of tea saponin, 1 to 2 parts of palm oil, 0.1 to 0.2 parts of nanosilicon dioxide and 10 to 15 parts of water. The moth-proof down composite thermal material disclosed by the invention not only has an excellent thermal insulation property, good breathable and moisture absorbing properties and good elastic resilience and high strength, but also has good insect-resistant and moth-proof performances, is beneficial to storing products and is good in use performance.
Description
technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a mothproof down composite thermal insulation material and a preparation method thereof. Background technique [0002] Down is a kind of natural protein fiber material, which is widely used as a textile material due to its excellent elasticity, moisture absorption and breathability. Among the four natural thermal insulation materials of cotton, wool, silk and down, down has the best thermal insulation performance. The most traditional use of down is as a filling material for various thermal products, mainly clothing and bedding. The products are soft, fluffy, elastic, and have good warmth retention properties, and are widely welcomed. However, down has poor strength, is easy to break after long-term use, and has low durability; after absorbing moisture, the warmth retention effect decreases, and the source is tight, expensive, easy to be eaten by insects, and easy to b...
