Detailed Description
The fillable structure of the present invention comprises a top layer, an inner layer, and an intermediate layer. The surface and inner layers can be made of fabrics with the same material or fabrics with different materials. The middle layer is a continuous tubular fabric structure, and the structure can be an integrally formed continuous tubular structure or a continuous tubular structure formed by sewing or splicing a plurality of tubular structures. In view of convenience of production and labor cost, the intermediate layer is preferably an integrally formed continuous tubular fabric structure. In the invention, the middle layer is of a continuous cylindrical design, can be used for filling materials, does not need to be quilted into a grid or diamond shape and the like in order to ensure uniform distribution of the filling materials like a conventional down jacket and a cotton garment, and realizes the freedom of appearance design; under the same conditions, the content of static air is increased, the heat preservation property is improved, and the uniform distribution of filling materials can be ensured.
In view of weight reduction, wearing feeling, and the like, the weight of the intermediate layer is preferably not greater than the sum of the weights of the top layer and the back layer. Namely, the gram weight of the surface layer is marked as X, the gram weight of the inner layer is marked as Y, and the gram weight of the middle layer is marked as Z; x, Y and Z satisfy the following relation: z is less than or equal to X+Y.
Generally, in order to ensure no down leakage in cotton wear, down jackets and other applications, an inner liner with a small underfill coefficient is used as the middle layer, but the smaller the underfill coefficient is, the more closely the yarns in the fabric are arranged, and under the same condition, the larger the gram weight of the fabric is. Preferably, the intermediate layer of the present invention has a structure with an underfill coefficient of 30.0 to 45.0, and the movement of the filler is restrained by the knitted structure of the intermediate layer. If the underfill coefficient of the intermediate layer is less than 30.0, the weight of the intermediate layer tends to increase, possibly affecting the wearing feeling; if the underfill coefficient is higher than 45.0, the intermediate layer structure is relatively loose, the filler is not easily attached, and the filler accumulation improving effect tends to be reduced. In view of weight reduction, the intermediate layer of the present invention is more preferably a structure having an underfill coefficient of 35.0 to 45.0.
The yarn types forming the top layer, the inner layer, and the middle layer are not particularly limited, and may be one or more of polyamide 6 (hereinafter, nylon 6), polyamide 66 (hereinafter, nylon 66), polyethylene terephthalate (hereinafter, PET), polybutylene terephthalate fiber (hereinafter, PBT), and polytrimethylene terephthalate fiber (hereinafter, PTT).
Preferably, the intermediate layer has a friction band voltage of 0 to 3X 10 3 V is provided. The friction band voltage of the intermediate layer exceeds 3×10 3 V, the problem of mutual adsorption and adhesion of the middle layer, the surface layer and the inner layer can possibly occur in the wearing process, thereby affecting the wearing comfort.
Preferably, the yarn titer used for the top layer, the inner layer and the middle layer of the fillable structure of the present invention is 7 to 100 deniers (D), more preferably 10 to 50D. In addition, in view of the use as down jackets or cotton jackets, low air permeability and light weight are necessary, and therefore, it is preferable to use a low denier high density woven fabric for the top and bottom layers. The low denier high density woven fabric is a woven fabric having a yarn fineness of 10 to 50D and a cover factor of 1500. Of course, such high density woven fabrics may also be somewhat elastic.
Preferably, the intermediate layer is integrated with the top and bottom layers by partial connection at a distance of 1000cm 2 The unconnected area per unit area is 100cm 2 The above. Considering that the large area connection would make the design of the fabric too single, it is further preferred that every 1000cm 2 The unconnected area per unit area is 500cm 2 The above. The connection mode can be a fitting connection or a needle seam connection, wherein the needle seam connection can be a line connection or a point connection. Considering that the middle layer is preferably in a sparse structure, the problem of glue leakage easily occurs during the lamination connection, the adhesion of the fabric is likely to be caused, and the use of glue is likely to influence the hand feeling, so that the connection mode is preferably in a stitch connection. Considering that the use of a large area of stitches for the stitch connection would affect the aesthetic appearance of the design and would increase the cost, it is more preferable to use stitches per 1000cm 2 The unconnected area per unit area is greater than or equal to 950cm 2 And less than 1000cm 2 。
Preferably, in the continuous tubular fabric structure of the intermediate layer of the present invention, the width between the connecting lines is between 2cm and 60 cm. Considering that the width between the connecting lines exceeds 60cm, the binding is less, and the effect of improving the down pile prevention tends to be lowered. Further preferably, the width between the connecting lines is between 2cm and 30 cm. More preferably, the width between the connecting lines is between 4cm and 10 cm.
When the light transmittance (at the time of double-layer tiling) of the continuous tubular fabric structure of the intermediate layer is more than 70.0%, the fabric structure has a large void, and there is a possibility that the filler leaks out, so that the light transmittance (at the time of double-layer tiling) of the intermediate layer is preferably 70.0% or less in the present invention. When the light transmittance of the middle layer is less than 30.0%, the fabric structure has smaller gaps, and the fabric has larger gram weight, so that the light weight can be possibly influenced. Therefore, in the present invention, the light transmittance of the intermediate layer (when the two layers are laid flat) is more preferably 30.0% to 70.0%. More preferably, the light transmittance of the intermediate layer (when the double layers are tiled) is between 30.0% and 50.0%.
Preferably, the intermediate layer of the present invention is filled with a filler material. The filler is not particularly limited, but is preferably one or more of down, wool, cotton, silk, viscose and chemical fiber, and more preferably down. The chemical fibers may be polyester fibers, polyacrylonitrile fibers, or the like.
