Embodiment Construction

[0014] Non-limiting examples of the present invention are as follows:

[0015] An antibacterial and mildew-resistant down composite thermal insulation material is prepared from the following component raw materials in weight (kg):

[0016] Duck down 35, soybean fiber 4, bamboo fiber 12, polylactic acid composite fiber 15, polyvinyl alcohol fiber 8, lauric monoglyceride 0.3, polyvinylpyrrolidone 0.8, coconut 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-550 0.4; the preparation method of the polylactic acid composite fiber is to prepare shell powder After mixing with 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, and then use a twin-screw extruder to make materials at 160-180°C, and then use...

Abstract

The invention discloses an antimicrobial mildew-proof down composite warmth retention material. The down composite warmth retention material is characterized in that the down composite warmth retention material is prepared from raw materials comprising, by weight, 30-40 parts of eider, 3-5 parts of soybean fibers, 10-15 parts of bamboo fibers, 10-20 parts of polylactic acid composite fibers, 5-10 parts of polyethelene alcohol fibers, 0.2-0.4 parts of glycerol monolaurate, 0.5-1 parts of polyvinylpyrrolidone, 1-2 parts of coconut oil, 0.1-0.2 parts of nanometer silica, and 10-15 parts of water. The down composite warmth retention material has excellent warmth retention performance, is high in air permeability, hygroscopicity, resilience and strength, has good antimicrobial mildew-proof performance and using performance, and facilitates the hygiene of products and human health.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to an antibacterial and mildew-resistant 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...
