Abstract

The invention provides a multilayered fiber heat insulation material structure formed mainly by clamping parallel long cotton fiber webs, which have been processed by folding, between two layers of upper and lower short cotton fiber webs added with hot melt fiber. After cross-lamination shaping and thermal-setting, a structure having multilayered fiber stacked layers is formed. Then, it is cut and sewed between a surface cloth and a lining cloth of the upper and lower surface layers to form the heat insulation material structure having multilayered fiber layers. By utilizing the cohesion between fibers of the short cotton fiber web, the horizontal positioning between the parallel long cotton fiber web is fixed. However, the flexible stretching feature of the parallel long cotton fiber web in the vertical direction is retained, so that the long cotton fiber webs clamped between the short cotton fiber webs within the heat insulation material can be flexibly moved in the middle of the fiber layer to avoid the situations of fiber sticking or worse resilience. The whole heat insulation material does not become rigid and lose the skin-tightness caused by the thickness of cotton layer, thereby keeping the skin-tight sag with good softness. Simultaneously, the long cotton fiber web layer can be integrally combined with the sewing place of the surface and lining cloths to effectively loosen the sewing gaps, thereby improving the problems of crack on cotton webs due to pulling/dragging and water rinsing.

Description

Multilayer fiber insulation structure

The invention relates to a multi-layer fiber thermal insulation material structure, in particular to a long-fiber cotton web and a short-fiber cotton web which are laminated in a composite manner, and formed into a good fit and compression recovery after cross-stacking and shaping. Insulation material structure with characteristics such as processability.

Among the commercially available garments, sleeping bags, bedding and other products, the medium and thick insulation materials generally use a multi-layered short-fiber cotton mesh structure, and the short fiber itself has the characteristics of better fiber cohesion. Short-slit seams (10cm for general garments, 20cm for sleeping bags or bedding). In order to improve the easy cutting of the insulation material, the sewing process and the improvement of the degree of washing resistance, it is often necessary to add hot-melt fiber or spray resin to the staple fiber web to strengthen the structural force, but this results in the fit and sag of the insulation material. And the resilience after compression is not good, and in this case, the thicker the thickness of the heat insulating material, the situation is obvious.

In order to solve the aforementioned problems existing in existing products, a new design is needed in order to effectively solve the problems that are difficult to break by existing products.

In view of the deficiencies of the existing technologies described in the above background of the invention, in order to meet the needs of industrial interests, the present invention provides a multi-layer fiber insulation material structure which utilizes a parallel filament cotton web which has been folded and folded to be clamped on the upper and lower sides. Between the short-staple cotton webs with hot-melt fibers added, after cross-layering forming and heat setting, a fiber laminated structure capable of relatively elastic sliding between the fiber layer and the fiber layer is formed, which is then cut and sewn into The heat insulating material structure having the multilayer fiber layer of the present invention is formed between the upper and lower table and the inner cloth.

The invention utilizes the cohesion between the fibers of the staple fiber web in the composite fiber layer to fix the lateral positioning (left and right displacement) between the long filaments of the parallel filament cotton web, but still maintains The elastic tensile properties of the parallel filaments in the 緃 direction make the insulation material not stiff, not close to the body due to the thickness of the cotton layer, and maintain a good soft body sag. In addition, since the long-fiber cotton net is sandwiched between the upper and lower staple fiber webs, when the heat-insulating material is pressed, the long-fiber cotton net can be brought into a state of cohesion between the fibers and the fibers due to the pressure. The lower layer of short-staple cotton web bounces the upper and lower layers of staple fiber cotton webs due to the folded long filaments, thereby providing a better fiber elastic restoring force of the heat-insulating material after compression. In addition, the continuous long-fiber cotton mesh layer of the invention is integrated with the surface of the table and the inner cloth, so that the short-fiber cotton web is not easily broken when being stretched or rebounded, thereby effectively relaxing the spacing of the seam and improving the seam. The problem is that the cotton web breaks due to pulling or washing.

Because it is known to use a multi-layer staple fiber web to make a heat-insulating material with a certain thickness, in order to consider its workability, avoid stretching and cracking, and improve the washing resistance, etc., it is strengthened by adding hot-melt fiber or spraying resin. Structural strength, but also causes shortcomings such as lack of fit, structural rigidity, insufficient sag, and poor recovery after compression; however, the present invention takes advantage of the ease of processing of staple fibers, and combines the twisted parallel filaments. With drafting and resilience, when it is combined with the staple fiber to form a multi-layer cotton web, the composite cotton layer can be prevented from being broken during stretching or rebound, so that the heat insulating material has a certain thickness and can remain relatively Good soft body and sag, and it is not easy to be broken with elastic table and lining for stretching and washing. The structure design of parallel filament cotton web with short fiber cotton net can avoid the long-fiber cotton net. The problem of processing and cutting increases the workability, and the staple fiber web has the characteristics of increasing the density of the cotton mesh, and in addition to being easy to process, it also has the function of reinforcing the gap between the filaments of the long-fiber cotton mesh. Therefore, the multi-layer cotton net design of the invention not only has the fiber characteristics inherent in the long and short fiber cotton nets, but also has the composite design which multiplies the overall product effect of the heat insulating material, and completely improves the existence of the conventional products. The problem.

The invention is discussed herein as a multi-layer fiber insulation material structure, in particular, a method of using a folded parallel filament cotton web to be sandwiched between upper and lower layers and having hot melt fibers. Between the staple fiber webs, after cross-stacking forming and heat setting, a fiber laminated structure capable of relatively elastic sliding between the fiber layer and the fiber layer is formed, and then cut and sewn on the upper and lower layers. Between the linings, to form a heat insulating material structure having a multilayer fiber layer of the present invention. Through the cohesion between the fibers of the staple fiber web, the lateral positioning (left and right displacement) between the filaments of the parallel filament cotton web can be fixed, but the elastic stretch sliding of the parallel filament web in the 緃 direction is maintained, so that the overall insulation material is The parallel long-fiber cotton mesh can be elastically moved between the fiber layers of the staple fiber web to avoid the situation of fiber sticking or poor resilience, and it is not stiff and not close to the thickness of the cotton layer, and maintains a good soft body sag. At the same time, the continuous long-fiber cotton mesh layer combined with the surface of the table and the inner cloth can effectively relax the sewing space, improve the problem of the cotton net due to pulling or washing and rupture, and provide suitable for clothes such as ready-to-wear, sleeping bags and bedding.

The fiber laminate is further laminated to form a cross-laminated fiber laminate as shown in the second figure, and then subjected to heat setting treatment to form a relatively elastic sliding relationship between the fiber layer and the fiber layer. The fiber laminate structure, the fiber laminate is further cut, sewn on the upper and lower table, and between the inner cloth (3) and (4), thereby forming the heat insulating material structure having the multilayer fiber layer of the present invention. After the cross-layering of the fiber layer of the present invention, the structure of the fiber layer is as shown in the third figure. As shown in the figure, the present embodiment mainly uses a double-layer long-fiber cotton web (1) as an example. It is also possible to use four or six or more double-layered long-fiber cotton webs (1) depending on the thickness, and placed between the upper and lower layers of the hot-melt staple fiber web (2) instead of Limiting the thickness thereof; as described above, the present invention mainly utilizes the long-fiber cotton web (1) which has been folded and folded between the upper and lower layers of the staple fiber web (2) to which the hot-melt fiber is added. The fiber laminate is formed, and after being cross-laminated, the parallel filament cotton web (1) is also separated from the short cross-wax web (2) by separating the upper and lower parallel staple fiber webs (2). The staple fiber crossover web (5) formed by the fiber web (2); as shown in the third figure, the fiber laminate after cross-stacking mainly comprises upper and lower double-layer parallel filament webs (11) (12), a staple fiber web (21) (22) sandwiched between the upper and lower layers of the upper long-fiber web (11), and the upper and lower layers of the lower laminate long-staple web (12) Short staple cotton web (23) (24); The staple fiber web (22) (23) between the upper and lower laminates forms a staple fiber crossover web (5) due to the cross-layout relationship, thus, in each layer of staple fiber web (2) Or a pair of staple fiber webs (1) are interspersed between the staple fiber crossover webs (5) to form the main structural features of the present invention.

As shown in the third and fourth figures, when the cross-layered fiber laminate is properly cut, a table cloth (6) is sewn on the upper and lower layers by sewing (6). And a lining cloth (4) to form the heat insulating material structure of the present invention having a plurality of fiber layers.

The invention utilizes the cohesion between the fibers of the staple fiber web (2) in the composite fiber layer to fix the lateral positioning (left and right displacement) between the filaments of the parallel filament cotton web (1), but still maintain the parallel filament web (1) The elastic tensile property in the 緃 direction, when the thermal insulation material is under stress, the parallel filament cotton web (1) between the fiber layers can be elastically moved to avoid the occurrence of fiber smear or poor resilience, etc. It does not become stiff due to the thickness of the cotton layer, does not fit close to the body, and maintains a good soft fit. As shown in the fifth figure, it shows that the actual application of the present invention on the garment product, the fiber change diagram generated when the force is different, and the sixth and seventh figures, the invention is shown to be subjected to the force pull. The fiber change diagram of the stretch and elastic recovery; wherein, in the fifth figure, when the fiber laminate of the present invention is subjected to bending (such as the change of the right fiber structure), it is located in the staple fiber web (21) (24) and the staple fiber. The twisted long-staple cotton web (11) (12) between the cross-webs (5) can produce elastic stretch sliding in the longitudinal direction thereof, and the thickness of the fiber laminate is compressed, so that the heat-insulating material of the present invention is soft and close-fitting. Characteristics, without affecting its fit and fiber sag due to its thickness; and when the fiber laminate of the present invention is unstressed (such as the left fiber structure change diagram), then the folded parallel filament web (11) (12) is elastically folded, separating the upper and lower staple fiber webs (21) (24) and the staple fiber crossover webs (5), so that the fiber laminate maintains a considerable thickness.

In addition, as shown in the sixth and seventh figures, the fiber change of the present invention when subjected to force stretching and elastic recovery is more specifically shown, as shown in the sixth figure, when the fiber laminate of the present invention is stretched under force. When the staple fiber web (11) (12) between the staple fiber web (21) (24) and the staple cross cotton web (5) can produce elastic stretch sliding in the longitudinal direction, So that the fiber laminate as a whole does not appear stiff and more soft and close, at this time, the staple fiber in the staple fiber web (21) (24) and the staple fiber crossover web (5) is parallel to the long fiber. The fiber cohesion formed between the long filaments of the cotton web (11) (12) causes the staple fiber web (21) (24) and the staple cross cotton web (5) to not crack during the stretching process. In the case, the density distribution of the fibers is released (as shown); when the force is released, as shown in the seventh figure, the folded parallel filament web (11) (12) exhibits a fiber elastic recovery state. Short staple cotton web (21) located on the upper and lower layers (2 4) and the staple fiber crossover web (5) restores the density of the fibrils, and the fiber laminate returns to a considerable thickness.

It is worth mentioning that the present invention is folded between the upper and lower staple fiber webs (2) by using parallel filament cotton webs (1), and the heat insulating material can be folded after being released by the compressive force. The long-fiber cotton web (1) is a short-staple cotton web (2) which is in a state of cohesion between fibers and fibers due to compression, and a staple fiber web which is woven by the upper and lower layers due to the long filaments which are folded. (2) Bounce, providing good thermal recovery of the thermal insulation material after compression.

The invention adopts the characteristics that the short-fiber cotton web (2) is easy to process, and combines with the long-fiber cotton web (1) with drafting and resilience, when it is combined with the staple fiber web (2) to form a multi-layer cotton layer. The composite cotton layer can be prevented from being broken when stretched or rebounded, so that the heat insulating material can have a certain thickness, but still can maintain a fairly good soft body sag, and can be matched with an elastic watch and a lining cloth ( 3) (4) Sewing, so that the continuous filament cotton web (1) is integrated with the watch and the inner cloth (3) (4), so that the staple fiber web (2) is stretched or rebounded. It is not easy to crack, so it can effectively relax the gap between the seams and improve the fiber web due to pulling or washing. In addition, the short-fiber cotton mesh (2) is used to sandwich the long-fiber cotton mesh (1) structural design, which can avoid the problem that the long-fiber cotton mesh (1) cannot be processed and cut, and the processing property is increased, and the short-fiber cotton is added. The net (2) has the property of increasing the density of the cotton web, and in addition to being easy to process, it also has the function of reinforcing the gap between the filaments of the long-fiber cotton web (1). Therefore, the multi-layer cotton net design of the present invention not only combines the fiber characteristics inherent in the long and short-fiber cotton webs (1) and (2), but also the composite design is multiplied by the overall product efficacy of the thermal insulation material, and is completely improved.
