Description
Technical Field
The invention relates to a garment, in particular to a thin-layer heat-preservation down jacket.
Background
The heat preservation of the existing down jackets basically depends on the heat insulation effect of down, so that the heat transfer between a human body and air is reduced. In order to improve the heat preservation effect, the existing means mainly adopts down materials with better heat preservation effect such as goose down or the like by increasing down filling amount. However, the price of the down is higher, the cost of the down jacket is greatly increased due to the increase of the down filling amount and the selection of the higher-quality down, the thickness of the garment is larger due to the increase of the down filling amount, the whole garment is bulked after wearing, the activity amplitude is limited, and the wearing comfort is reduced.
In the prior art, attempts are also made to achieve a higher heat-insulating effect from the heat-insulating principle, for example, far infrared fibers are used for making clothes. The principle of far infrared fiber is to absorb some of the infrared radiation emitted by human body by utilizing fiber characteristics and then release the infrared radiation which can be absorbed by human epidermis. In the process of emitting infrared radiation by the far infrared fiber, the infrared radiation is not fixedly directed, namely is scattered, and only the infrared radiation directed to the epidermis of the human body can be absorbed again by the human body, so that far infrared heat preservation can essentially block or intercept only a small part (about 35%) of the infrared radiation from the human body, and the rest part still can be emitted into the outside air to cause heat dissipation in the process of emitting the infrared radiation by the far infrared fiber. It is the knowledge of this defect, so the far infrared fiber is mainly used for making thermal underwear at present, and is rarely used for thermal insulation of outerwear directly.
Chinese patent CN113287817a discloses another attempt to block heat radiation. The down jacket fabric is provided with a metal foil or the like or a polymer film layer or a heat preservation coating containing infrared reflection pigment. The down jacket fabric has the function of reflecting infrared radiation, and can intercept most of infrared radiation emitted by a human body, so that the down jacket fabric has a better heat preservation effect. But obviously, the whole fabric of the down jacket is fully coated or fully coated with the coating, the metal foil or the polymer film; this easily causes the following drawbacks: 1. in the wearing process, a large part of the fabric can generate continuous friction with other objects, such as friction between the inner side of an arm and a body part during walking, friction between the back and a chair back in a sitting posture state and the like, so that the functional accessories are easy to fall off and the heat preservation effect is lost; 2. fully distributing the functional accessories on the down jacket fabric can block the ventilation channel of the down jacket, so that the down jacket has no functions of exhausting air and removing moisture; 3. the cost is too high.
Disclosure of Invention
The invention aims to: the invention aims to provide a down jacket with low cost, air permeability, moisture permeability, low down filling amount and durability and high thermal insulation performance.
The technical scheme is as follows: the thin-layer heat-insulating down jacket comprises a fabric, a lining and down, wherein a plurality of inclined connecting belts are connected between the fabric and the lining, and a plurality of down filling cavities are formed by enclosing the fabric, the lining and the connecting belts for filling down; wherein, the connecting band can reflect infrared radiation to one side of the lining.
The thin-layer heat-preservation down jacket comprises a fabric with tensile strength and a functional layer with infrared radiation reflection performance, wherein the functional layer is compounded on the fabric.
The thin-layer heat-insulating down jacket is characterized in that the functional layer is selected from a metal foil layer, a high-molecular film or a heat-insulating coating containing infrared reflective pigment.
The cross section of the down filling cavity comprises a trapezoid, a triangle or a non-right-angle parallelogram.
The thin-layer heat-preservation down jacket is characterized in that the inclined connecting belt is arranged between the fabric and the lining at the same inclination angle.
The thin-layer heat-preservation down jacket is characterized in that the inclined connecting bands are arranged between the fabric and the lining at different inclination angles.
The thin-layer heat-preservation down jacket is characterized in that different inclination angles refer to left inclination of part of the connecting belt and right inclination of part of the connecting belt.
The thin-layer heat-insulating down jacket is characterized in that different inclination angles are shown on the left side of the connection point of part of the connection belt and the fabric and the connection point of the part of the connection belt and the fabric and the right side of the connection point of part of the connection belt and the fabric.
The thin-layer heat-insulating down jacket is provided with a plurality of direct suture lines for directly sewing the fabric and the lining together.
The thin-layer heat-preservation down jacket is characterized in that projection overlapping areas exist on the head section and the tail section of two adjacent connecting belts in the vertical direction.
Preferably, the connecting belts can be connected with the fabric and the lining material in a certain area at the same inclination angle, and projection overlapping areas exist at the head section and the tail section of two adjacent connecting belts in the vertical direction, so that a shielding layer capable of reflecting infrared radiation can be constructed between the fabric and the lining material of the down jacket, and meanwhile, ventilation and moisture permeable channels remain between the two adjacent connecting belts; therefore, on the premise of not reducing the effective area of the breathable and moisture permeable channel (almost no reduction compared with a down jacket without infrared shielding measures), the infrared shielding function is increased, and the infrared shielding function is matched with the down filled in the down filling cavity, so that two synergistic heat insulation effects of blocking heat transfer and blocking heat radiation can be realized, the excellent heat insulation effect can be realized by using less down filling amount, the whole thickness of the down jacket is thinned, and the wearing comfort and economy are improved.
On the other hand, the infrared shielding layer is arranged between the fabric and the lining, so that the functional material on the shielding layer can be prevented from falling off due to friction, and the durability of the functional material is improved.
As a further improvement, the connecting bands can be arranged between the fabric and the lining at different angles of inclination, such as, for example, in a certain region of the down jacket, three adjacent (also other numbers of) connecting bands are connected between the fabric and the lining at the same angle (for example, 60 degrees), the three connecting bands can be defined as a left-inclined combination, and three other connecting bands adjacent to the three connecting bands are connected between the fabric and the lining at another angle (for example, 120 degrees); any two adjacent connecting bands in the same left-inclined combination or right-inclined combination and the fabric and lining enclose a non-right-angle parallelogram down filling cavity, and two connecting bands directly adjacent to the left-inclined combination and the right-inclined combination enclose a trapezoid or triangle down filling cavity with the fabric and the lining.
Compared with the mode of adopting the same inclination angle, the arrangement has the advantages that the arrangement can limit the range of mutual dislocation (eiderdown migration and agglomeration) of the fabric and the lining, can ensure the basic stability of the inclination direction of the connecting belt, can not greatly change the angle of the connecting belt due to dislocation of the fabric and the lining, and reduces the infrared reflectivity. For example, when the connecting band is inclined right at the same inclination angle in a plane view, the lining is pulled right, which is limited by the connecting band, so that the movement range is limited, but if the lining is pulled left, the inclination direction of the connecting band is completely changed (if the lining is changed to 90 degrees, the infrared reflection function is completely lost), and the lining is greatly moved left, which is obviously disadvantageous for keeping the infrared reflection effect and the down filling stability.
However, if the connecting bands are inclined to the right and the connecting bands are inclined to the left in the same region, the lining is limited by a part of the connecting bands and cannot move greatly whether the lining is pulled to the left or to the right relative to the fabric. The connecting belt can be ensured to be always at an effective reflection angle to a great extent, the large-amplitude dislocation of the fabric and the lining can be limited, and the migration and agglomeration of down feather are prevented.
Preferably, the three-dimensional display of the down jacket further comprises direct stitching lines (areas where the fabric and the lining are directly stitched) for dividing the down jacket into a plurality of filling areas, and each filling area can comprise a plurality of down filling cavities. Since the direct stitch lines are formed by directly stitching the fabric and the lining, there is little down filling in the vicinity of the direct stitch lines, which is a significant drawback of conventional down jackets, which results in little insulation in this area. In the prior art, more direct sutures are often required to limit migration and agglomeration of down, which can lead to further reduction of the heat preservation effect.
However, as mentioned above, the present invention has an advantage in that the present invention requires that the head and tail sections of two adjacent connecting bands have a projected overlap in the vertical direction, so that at the location of the direct seam, the connecting bands will form a complete coverage of the direct seam, so that although there is no down filling at the direct seam, it is capable of achieving complete reflection of the infrared radiation directed at the area (irrespective of the loss of infrared radiation due to material properties), and therefore has superior thermal insulation properties.
The beneficial effects are that: compared with the prior art, the invention has the following advantages: (1) The down jacket has the advantages of low cost, air permeability, moisture permeability, low down filling quantity, durability and high heat preservation performance. (2) Under the same direct suture condition, the existence of the connecting band can make the down less likely to undergo migration and agglomeration. (3) The infrared shielding layer is arranged between the fabric and the lining, so that the functional material on the shielding layer can be prevented from falling off due to friction, and the durability of the functional material is improved. (4) A ventilation and moisture permeable channel is reserved between two adjacent connecting bands; therefore, on the premise of not reducing the effective area of the breathable and moisture permeable channel (almost no reduction compared with a down jacket without infrared shielding measures), the infrared shielding function is increased, and the infrared shielding function is matched with the down filled in the down filling cavity, so that two synergistic heat insulation effects of blocking heat transfer and blocking heat radiation can be realized, the excellent heat insulation effect can be realized by using less down filling amount, the whole thickness of the down jacket is thinned, and the wearing comfort and economy are improved.

Detailed Description
Examples
As shown in fig. 1, the thin-layer heat-insulating down jacket comprises a fabric 1, a lining 2 and down 5, wherein a plurality of inclined connecting belts 3 are connected between the fabric 1 and the lining 2, and the fabric 1, the lining 2 and the connecting belts 3 enclose a down filling cavity 4 for filling the down 5; wherein the connecting band 3 is capable of reflecting infrared radiation towards the inner material 2 side.
The connecting belt 3 can be a composite structure of a common fabric with a certain tensile strength and a functional layer capable of reflecting infrared radiation, wherein the common fabric is used for realizing the connection and fixation of the fabric 1 and the lining 2 and preventing the migration and aggregation of down feather caused by large dislocation of the fabric and the lining; the functional layer is a metal foil layer, a polymer film or a heat-insulating coating containing infrared reflection pigment.
The connecting strips 3 should be arranged obliquely relative to the fabric 1, the lining 2 so as to enclose with the fabric 1, the lining 2a down filling cavity 4 having a trapezoid, triangle or non-right-angle parallelogram cross section.
Preferably, the connecting bands 3 can be connected with the fabric 1 and the lining 2 at the same inclination angle in a certain area in the manner shown in fig. 1, and the head and tail sections of two adjacent connecting bands 3 are provided with projection overlapping areas in the vertical direction, so that a shielding layer capable of reflecting infrared radiation can be constructed between the fabric 1 and the lining 2 of the down jacket, and meanwhile, ventilation and moisture permeable channels are reserved between the two adjacent connecting bands 3; therefore, on the premise of not reducing the effective area of the breathable and moisture permeable channel (almost no reduction compared with a down jacket without infrared shielding measures), the infrared shielding function is increased, and the down jacket is matched with down filled in the down filling cavity 4, so that two synergistic heat insulation effects of blocking heat transfer and blocking heat radiation can be realized, the excellent heat insulation effect can be realized by using less down filling amount, the whole thickness of the down jacket is thinned, and the wearing comfort and economy are improved.
On the other hand, the infrared shielding layer is arranged between the fabric 1 and the lining 2, so that the functional material on the shielding layer can be prevented from falling off due to friction, and the durability of the functional material is improved.
Examples
As shown in fig. 2, the thin-layer heat-insulating down jacket comprises a fabric 1, a lining 2 and down 5, wherein a plurality of inclined connecting belts 3 are connected between the fabric 1 and the lining 2, and the fabric 1, the lining 2 and the connecting belts 3 enclose a down filling cavity 4 for filling the down 5; wherein the connecting band 3 is capable of reflecting infrared radiation towards the inner material 2 side.
As a further improvement, the connecting bands 3 may be disposed between the fabric 1 and the lining 2 at different inclination angles, as shown in fig. 2, for example, in a certain area of the down jacket, three adjacent (or other number of) connecting bands 3 may be connected between the fabric 1 and the lining 2 at the same angle (for example, 60 degrees) (the three may be defined as a left-inclined combination), and another three adjacent connecting bands may be connected between the fabric 1 and the lining 2 at another angle (for example, 120 degrees) (the three may be defined as a right-inclined combination); any two adjacent connecting bands 3 in the same left-inclined combination or right-inclined combination and the fabric 1 and the lining 2 enclose a non-right-angle parallelogram down filling cavity 4, and two connecting bands 3 which are directly adjacent to the adjacent left-inclined combination and right-inclined combination enclose a trapezoid or triangle down filling cavity 4 with the fabric 1 and the lining 2.
Such an arrangement has an advantage over the arrangement shown in fig. 1 in that it is capable of limiting the magnitude of mutual dislocation (which causes migration and agglomeration of down) between the fabric 1 and the lining 2, and also capable of ensuring substantial stability of the direction of inclination of the connecting band 3 without causing substantial change in the angle of the connecting band 3 due to dislocation of the fabric 1 and the lining 2, and reducing the infrared reflectivity. For example, in the manner shown in fig. 1, pulling the backing material 2 to the right is limited by the connecting band 3, and thus the movement range is limited, but if pulling the backing material 2 to the left in fig. 1, the tilting direction of the connecting band 3 is completely changed (if changed to 90 degrees, the infrared reflection function is completely lost), and the backing material 2 is moved to the left by a large extent, which is obviously disadvantageous for maintaining the infrared reflection effect and the down filling stability.
However, the embodiment shown in fig. 2 is different, because in the same area, there are both connecting bands 3 inclined to the right and connecting bands 3 inclined to the left, and therefore, the lining 2 is limited by a part of the connecting bands 3 and cannot move significantly, whether it is pulled to the left or to the right with respect to the face fabric 1. The connecting belt 3 can be ensured to be always at an effective reflection angle to a great extent, and the large-amplitude dislocation of the fabric 1 and the lining 2 can be limited, so that the migration and agglomeration of down feather are prevented.
Examples
As shown in fig. 3, fig. 3 is a perspective view of the manner of fig. 2, and fig. 3 includes direct stitching lines 6 (the areas where the fabric 1 and the lining 2 are directly stitched) for dividing the down jacket into a plurality of filling areas, and each filling area may include a plurality of down filling cavities 4 therein. Since the direct stitch 6 is a direct stitch of the fabric 1 and the lining 2, there is little down filling in the vicinity of the direct stitch 6, which is a major drawback of conventional down jackets, which results in little insulation in this area. In the prior art, more direct sutures 6 are often required to limit migration and agglomeration of down, which can further reduce the heat preservation effect.
However, the present invention has an advantage that, preferably, the end-to-end sections of two adjacent connecting bands 3 have a projected overlapping area in the vertical direction (overlapping area shown by the dotted line in fig. 1), so that at the location of the direct stitch line 6, the connecting bands 3 will form a complete coverage of the direct stitch line 6, so that although there is no down filling at the direct stitch line 6, it can achieve a complete reflection of the infrared radiation directed to this area (irrespective of the infrared radiation loss due to the material properties), and thus still have a superior thermal insulation performance.
