Description
Technical field
The present invention relates to a kind of compound eider down flocculus and manufacture method thereof, particularly relate to a kind of three-layer sandwiched composite eiderdown flake and manufacture method thereof.
Background technology
Eider down derives from aquatic birds such as goose, duck, has been widely used as the stuffing of clothes and bedding as a kind of high-grade warming material, and its goods have gently, characteristic such as gentle, warming and comfortable.
The eider down high resilience, slim and graceful fluffy and soft, between suede piece and the suede piece, can both form certain clearance between pinnule and the pinnule, contain static air, so pyroconductivity is low, have good heat-insulating property.Simultaneously, as a kind of natural material, its goods very easily are subjected to consumer's favor.
Eider down comes the processing and fabricating down jackets as stuffing, and eiderdown quilt etc., this down products have gently, and is gentle, the advantage that warmth retention property is good.But also there are a lot of deficiencies in this down products: 1, eider down is had relatively high expectations to lining as packing material, otherwise brill suede phenomenon is very serious; 2, the general use of filling down products is the coating high density fabric, and this kind fabric mostly is chemical ﹠ blended fabric, and it is serious to wear electrostatic phenomenon in the winter time, and comfortableness is poor; 3, filling class down products volume is big, too fat to move, carries and store inconvenience.A common shortcoming of the heat insulating material formed existence of eider down class is anti-damaging by worms and the anti-poor performance of going mouldy, and antibacterial bacteriostatic need not use insect-proof agent or add chemical agent when depositing.
Animal and plant fiber is generally natural three-dimensional crimp, bulking intensity, good supporting force, integrates light, gentle, sliding, warm, high resilience.But animal and plant fiber generally comprises wool, cashmere, the rabbit hair, rabbit suede, camel hair, camel's hair, yakwool, mohair, silk, day silk, bamboo fibre, kapok, zein fiber, the fibre and soya of combing etc.
In the past animal and plant fiber in nonwoven material is produced, use and few, and animal and plant fiber generally also only uses long fiber in conventional fields such as spinning, staple fibre (below the 30mm) then can't use, and causes the waste of a large amount of animal fiber resources.
Disclosed at present application number 03100816.X, publication number CN1519410A, denomination of invention is the patent application of anti-chiseling down eider down composite flake, discloses a kind of anti-chiseling down eider down composite flake, comprises skin and intermediate layer.This skin is with hot melt polypropylene fibre net or terylene net, and the intermediate layer must use long fiber, and gas permeability, poisture-penetrability, warmth retention property are relatively poor, and feel is harder, and comfortableness also reduces greatly.This intermediate layer is that eider down is expected with the wadding that mixes of synthetic fiber, and must be doped with terylene, polyamide fibre, acrylic, viscose glue, wool long filament, yarn or slight knitting thing in the mixing wadding material, and long fiber or the separate fabric supporter as pulling force promptly wherein must be arranged.The final combination process of this anti-chiseling down eider down composite flake is that acupuncture or water jet process are made, and can cause the flocculus material more flat, real, not fluffy, thereby influence its insulation rate, shows 338g/m according to this patent disclosure data
2Material thickness 3mm only, insulation rate only 61.27%.
Another disclosed application number 200710027866.1, publication number CN101050583A, denomination of invention is the patent application of a kind of cellucotton and manufacture method, discloses a kind of cellucotton and manufacture method.This manufacture method, by open material, comb and parallel cotton fibers prior to spinning, moulding, heat baking bonding after, must carry out the quick cooling and shaping of pressure rolling while hot simultaneously, oven temperature must reach 180 ℃-200 ℃, higher to temperature requirement, energy resource consumption is bigger; Its carding is unidirectional combing, and the PRODUCTS FIELD of making differs greatly to the pulling force ratio, even can reach more than 10: 1, also carry out the quick cooling and shaping of pressure rolling while hot the time at last, complex process, and product is just pressed very thinly after the pressure rolling, bulking intensity is poor, and the insulation rate also descends thereupon greatly.
This shows that above-mentioned existing compound eider down flocculus and manufacture method thereof obviously still have inconvenience and defective, and demand urgently further being improved in structure, manufacture method and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product and method do not have appropriate structure and method to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of new three-layer sandwiched composite eiderdown flake and manufacture method thereof, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing compound eider down flocculus and manufacture method thereof exist, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of new three-layer sandwiched composite eiderdown flake and manufacture method thereof, can improve general existing three-layer sandwiched composite eiderdown flake and manufacture method thereof, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
