CN106510061A - New composite heat-insulation material and preparation method thereof - Google Patents

Abstract

The invention discloses a new composite heat-insulation material, which is prepared from the following components in percentage by mass: 30 percent of silk short threads, 40 percent of goose down, 15 percent of cony hair, and 15 percent of cashmere. A preparation method comprises the following steps of (1) after fully mixing the components in percentage by mass, firstly rinsing with flowing clear water for 5 to 10min; (2) selecting hydrogen peroxide aqueous with the concentration being 30 percent as a dip dyeing liquor, wherein the bath ratio is 1:1000; and warming and dip dyeing a rinsed mixture at the temperature of 80 DEG C for 2.3h; (3) after dip dyeing, stopping warming, continuously dipping the mixture in the hydrogen peroxide aqueous for 0.5h, and finally fishing out for standby use; (4) dehydrating the fished-out mixture in a dehydrator for 20 to 30min, and removing 60 percent of moisture; and (5) taking out the mixture from the dehydrator, placing in a steam drying room, setting the temperature of the drying room to be 50 to 70 DEG C, drying with steam for 4 to 6h until the moisture content of the mixture is below 13 percent, and obtaining the product. The new heat-insulation material prepared by the invention has the advantages of lightness, thinness, heat-insulation, gas permeability and good elasticity.

Description

A kind of composite heat insulation new material and preparation method thereof

Technical field

The present invention relates to a kind of composite heat insulation new material and preparation method thereof, is applied to down jackets processing technique field.

Background technology

Down jackets and eiderdown quilt are the essential products of winter people's warming, and the material of down jackets is main in the market For eider down and coated fabric, eider down refer in particular to it is long in geese and ducks abdominal part, into the fine hair of Flos Phragmitis piece shape, in the market, down jackets and Using pure down feather material as filling floss more than eiderdown quilt, down jackets are relevant with the content of eider down with the quality of eiderdown quilt, adopt merely It is with eider down as packing material, relatively costly, it is not suitable for crowd used, while pure eider down is not water-fastness, not light enough, also Groups of people are likely to become some anaphylactogens to duck's down allergy, pure eider down.

The content of the invention

It is above-mentioned for solving the problems, such as, the invention discloses a kind of composite heat insulation new material and preparation method thereof.

The invention discloses a kind of composite heat insulation new material, by mass percentage, is made up of following component：The short silk of silkworm silk 30%th, goose down 40%, the rabbit hair 15%, cashmere 15%.

The preparation method of the present invention is as follows：

Step one：Take above-mentioned mass fraction each composition be sufficiently mixed after, first with flowing clear water rinsing 5-10min；

Step 2：It is that 30% double itch aqueous solution as dip-dyeing solution from concentration, bath raio is 1:1000, heat up, by rinsing after it is mixed Compound contaminates 2.3h in the environment of 80 DEG C；

Step 3：After dip-dye, stop heating up, mixture is soaked 0.5h in hydrogen peroxide solution by continuation, is finally pulled out standby；

Step 4：Mixture after pulling out is placed in dewaterer and is dehydrated 20-30min, remove 60% moisture；

Step 5：Mixture is taken out from dewaterer, is positioned in steam drying room, drying room temperature is set to 50-70 DEG C, with steaming Vapour dries 4-6h, obtains final product this product to mixture water content to less than 13%.

The technical program is adopted, the invention has the beneficial effects as follows：Obtained new material has the characteristic of each composition, silkworm silk concurrently Most light most soft most thin natural fiber in nature, revocation external force easily can restore to the original state, at the same with it is good it is ventilative, Water vapour permeability；Goose down；Goose down bulkiness is good, warmth retention property is good；The smooth fluffy, thermal insulation in rabbit fur fibre surface；Cashmere is fine and smooth, soft Soft, fabric lines is close and thin, with good hygroscopicity and breathability.Therefore new material obtained in the present invention has frivolous, guarantor Warm, ventilative, the good advantage of elasticity, while the down jackets made using this material, next to the skin putting on can promote hair follicle activity, stimulate Blood circulation, has certain health-care effect to arthritis, scapulohumeral periarthritis, asthma.
