Abstract
The utility model relates to a fluffy thermal insulating floc piece with high rebound resilience, which is composed of an elastic framework made of three-dimensional crimp polypropylene or terylene long fiber which has fiber diameter within 17 micrometer to 65 micrometer and any one kind of melt-blown ultrafine fiber with diameter within 3 micrometer to 7 micrometer of polypropylene, polyethylene, polyester and nylon filled in the framework fiber gaps. The utility model has favorable rebound resilience.
Description
Technical field
The utility model belongs to insulation articles for use technical field, particularly a kind of wadding structural design of being taken.
Background technology
Existingly a kind ofly taken wadding and made by natural cotton, although the natural cotton flocculus has plurality of advantages, be subjected to the restriction and the natural cotton fiber poor flexibility of resource, yielding, lose bulkiness after the long-term use of wadding and become real, thus the warming deleterious of flocculus.Another kind is an eider down, and the good space structure of eider down determines that its thermal property is best, and eider down is made up of " plumage " and " suede " two parts.The diameter of " suede " is about 4～6 microns, and the thickest section diameter of " plumage " is about 40～60 microns, and in down jackets, " plumage " plays a supportive role, and makes it fluffy, can hold more air; " suede " is distributed in the 3-D solid structure that is supported by " plumage ", can stop the effect of air convection current in thermal layer.Arrange in pairs or groups when reasonable in the ratio of " plumage " and " suede ", its warmth retention property is best.But the resource-constrained of eider down costs an arm and a leg.
In the insulation flocculus material, polyester staple fiber has accounted for major part, is called dacron cotton, gum sprayed cotton, acupuncture cotton in the market at present, and its fibre diameter though can form three-dimensional structure, does not have the composition of " suede " at 15～35 microns, and heat insulation effect is also not ideal.Another is the polypropylene melt blown non-woven fabric of introducing in recent years, make U.S.A reach cotton, Taida's ecological cotton etc. on the market, the fibre diameter of melt spraying non-woven fabrics generally is 2～7 microns, the same with the diameter of " suede " in the eider down, comparing with other fiber is a rare advantage, but also brings tangible use limitation simultaneously.Because fibre diameter is too thin, inevitable rigidity deficiency, its Fiber Distribution is bidimensional substantially, makes that the nonwoven fabric bulkiness is very poor, feel and warming effect are all not so good.The eider down that this just is equivalent to not have " plumage " does not form three-dimensional structure, and heat insulation effect is not ideal.
The utility model content
The purpose of this utility model is for overcoming the weak point of prior art, design a kind of fluffy wadding with high resilience, can in use have good resilience, be to be difficult for the fluffy wadding of high resilience compacting, that warming effect is good.
A kind of fluffy wadding of the utility model design with high resilience, it is characterized in that, be that 17～65 microns three-dimensional crimp polypropylene fibre or terylene long fiber are elastic skeleton and to be filled in fibre diameter in the fibrous skeleton gap be that any one melt-blown micro fibre constitutes in 3～7 microns the polypropylene, polyethylene, polyester, nylon by fibre diameter.
The three-dimensional crimp elastic skeleton fiber of the fluffy wadding of high resilience can be determined according to instructions for use with the usage ratio that is filled in the melt-blown micro fibre in the fibrous skeleton gap, fibrous skeleton is 15%～85%, and the melt-blown micro fibre that is filled in the fibrous skeleton gap is 85%～15%.
The fluffy wadding of high resilience has good bulkiness, and the long-term use of flocculus still keeps fluffy state.Hole is many between the melt-blown micro fibre of filling, and not only can store more air but also can effectively stop air flowing in flocculus, and good heat insulation effect is arranged.Simultaneously, flocculus has the high ventilation poisture-penetrability, and quality is light, and is lighter by 1/3～1/2 than natural cotton flocculus under the situation of identical warming effect.
In the market, a kind of flocculus that mixes 15～35 micron diameter staple fibres in melt spraying non-woven fabrics is arranged, improved the bulkiness of melt spraying non-woven fabrics, but do not have good resilience.The utility model mixes fibre diameter in melt spraying non-woven fabrics be 17～65 microns three-dimensional crimp long fiber, and except the resilience of flocculus was fine, also have two important effects: one, the raw material of melt spraying non-woven fabrics can use polyethylene to be raw material.Because poly rigidity is all littler than other polymer such as polypropylene, some is satiny again, be furnished with the sensation of similar paraffin paper with it for the melt-blown nonwoven of raw material production, the bulkiness extreme difference has had the good fibrous skeleton of resilience just can effectively cut apart polyethylene fiber and has improved bulkiness.The polyethylene raw material resources are abundant, price is low, particularly can use reworked material, aspect environmental protection highly significant.Its two, melt spraying non-woven fabrics itself is powerful just very low, mixes behind the staple fibre powerful just lower; Improve brute force greatly and mix long fiber, improved serviceability.
Description of drawings
Fig. 1 is the embodiment one structural representation enlarged drawing of the fluffy wadding of the utility model high resilience.
Fig. 2 is the embodiment two structural representation enlarged drawings of the fluffy wadding of the utility model high resilience.
The specific embodiment
The fluffy wadding of high resilience of the present utility model reaches accompanying drawing in conjunction with the embodiments and further specifies as follows:
The structure of embodiment one as shown in Figure 1, comprise that the fluffy wadding of high resilience is that 36～65 microns three-dimensional crimp polypropylene fibre or terylene long fiber is elastic skeleton 2 by fibre diameter, with fibre diameter be that any one melt-blown micro fibre 1 is filled in the fibrous skeleton gap in 3～7 microns the polypropylene, polyethylene, polyester, nylon, be pressed into 2～15 millimeters lamella.
The structure of embodiment two as shown in Figure 2, comprise that the fluffy wadding of high resilience is that 17～35 microns three-dimensional crimp polypropylene fibre or terylene long fiber is elastic skeleton 2 by fibre diameter, with fibre diameter be that any one melt-blown micro fibre 1 is filled in the fibrous skeleton gap in 3～5 microns the polypropylene, polyethylene, polyester, nylon, be pressed into thickness and be 2～10 millimeters lamella, and be coated with anti-bonded non-woven fabrics surface layer 3 in this lamella above and below.
Claims (3)
1, a kind of fluffy wadding with high resilience, it is characterized in that, be that 17～65 microns three-dimensional crimp polypropylene fibre or terylene long fiber are elastic skeleton and to be filled in fibre diameter in the fibrous skeleton gap be that any one melt-blown micro fibre constitutes lamella in 3～7 microns the polypropylene, polyethylene, polyester, nylon by fibre diameter.
2, have the fluffy wadding of high resilience according to claim 1, it is characterized in that, the thickness of said flocculus is for being 2～15 millimeters.
3, have the fluffy wadding of high resilience according to claim 1, it is characterized in that, be coated with anti-bonded non-woven fabrics surface layer in said lamella above and below.
