Description

Technical Field

[0001] The invention relates to the technical field of home textile products, and in particular to an oblique-angle dislocation reinforced thermal insulation duvet and a processing method thereof. Background Art

[0002] Down quilts are the warmest quilts currently available. Their filling is mainly down, an animal protein fiber with higher thermal insulation performance than plant fibers such as cotton. Down spherical fibers are densely covered with millions of tiny triangular pores, which can shrink and expand with changes in temperature, producing a temperature regulating function. They can absorb the flowing heat emitted by the human body and isolate the entry of cold air from the outside.

[0003] The vertical lining process is widely used in the production of down quilts. The vertical lining is arranged horizontally and vertically to divide the interior of the down quilt into several three-dimensional small squares, such as Figure 1 As shown. All the horizontal linings and vertical linings are erected between the upper and lower quilt surfaces of the duvet. The vertical linings and the sides of each small square are provided with small openings for the filling tube to pass through, and each small square in the longitudinal direction shares the same filling channel. During the use of the duvet, the down in each independent small square in the quilt core will flow to each other, and the down at the corners will gather toward the center, making the distribution of the down in the small squares uneven, thereby reducing the thermal insulation performance of the duvet. At the same time, sharing the filling channel in the same longitudinal direction will cause the down to flow to each other easily. In the prior art, the purpose of preventing the down in adjacent grids from flowing to each other is achieved by tilting the horizontal lining at a certain angle and sewing the short horizontal lining that is also tilted to the filling channel position at the intersection of the horizontal lining and the vertical lining. This method solves the problem of down flowing, making the duvet have a stable structure and good warmth retention, but the required short horizontal lining increases the material cost, and the process steps are cumbersome, and the production cost of the duvet is relatively high.

[0041] In order to make the technical solution of the present application clearer, the technical solution of the present application will be clearly and completely described below through specific embodiments and in combination with the accompanying drawings of the embodiments of the present application. It should be noted that the described embodiments are partial embodiments of the present application, and the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention. For clarity and brevity, the description of known functions and structures is omitted in the embodiments.

[0042] like Figure 2-3 As shown, in one embodiment of the present invention, it relates to an oblique angle staggered reinforced thermal insulation duvet, which comprises a face 1 and a lining 2 arranged at intervals, a filling space is formed between the face 1 and the lining 2, a plurality of transverse linings 3 are distributed transversely in the filling space at a certain interval, a plurality of longitudinal linings 4 are distributed longitudinally in the filling space at a certain interval, and the plurality of longitudinal linings 4 and the plurality of transverse linings 3 are interlaced with each other to divide the filling space into a plurality of hexahedral spaces, each hexahedral space is a filling cavity, and the main feature of the duvet is that part of the transverse linings 3 and at least part of the longitudinal linings 4 are distributed in the filling space at an oblique angle α relative to the horizontal plane, so that the upper and lower ends of the longitudinal linings 4 are also sewn with the planes where the face 1 and the lining 2 are located at an oblique angle α, and at the same time, the upper and lower ends of the transverse lining 3 are also sewn with the planes where the face 1 and the lining 2 are located at an oblique angle α, forming at least a partial filling cavity 7 formed by the inclined transverse linings; in order to fill the filling cavity, as Figure 4 As shown, a plurality of unstitched sections are left on the horizontal lining 3 as filling openings 5, and the filling openings 5 ​​and the filling cavity in the same longitudinal direction form a filling channel; of course, in some other embodiments, a plurality of unstitched sections can also be left on the vertical lining 4 as filling openings, so that the filling openings and the filling cavity in the same transverse direction form a filling channel.

[0043] The duvet of the present invention distributes at least part of the horizontal lining and the vertical lining of the duvet at an oblique angle relative to the horizontal plane, and sews them at an oblique angle between the face and the lining, so that the filling space of the duvet is divided into a plurality of inclined hexahedral filling cavities, thereby solving the problem of the down at the corners in the filling cavity gathering toward the middle, making the down distribution of the duvet more uniform and enhancing the warmth retention performance.

[0044] In this embodiment, multiple horizontal linings 3 and vertical linings 4 are evenly arranged in the filling space, and the vertical linings 3 and the horizontal linings are completely distributed vertically and horizontally, and the angle between the two and the horizontal plane (face or lining plane) is 90°, so that the upper and lower bottom surfaces of the filling cavity formed in the filling space are rectangular. Of course, in some other embodiments, the vertical linings may be at a certain angle to the longitudinal direction of the horizontal plane, and the horizontal linings may be at a certain angle to the transverse direction of the horizontal plane, so that the upper and lower bottom surfaces of the filling cavity formed in the filling space may also be parallelograms. Of course, in this embodiment, it is preferred that the upper and lower bottom surfaces of the filling cavity are formed into rectangles so that each corner of the filling cavity can be easily filled in place. Furthermore, in order to consider the overall appearance and filling effect of the duvet, the present embodiment preferably makes the outermost transverse lining 3 and the longitudinal lining 4 of the duvet perpendicular to the horizontal plane, while the other transverse linings 3 and the longitudinal linings 4 are distributed at an oblique angle α relative to the horizontal plane, so that the side of the filling cavity in the transverse and longitudinal directions of the outermost side of the duvet will be a right-angled trapezoid, while the side of the other filling cavity will be a parallelogram, but this does not constitute a limitation of the present invention. In some other embodiments, all the transverse linings 3 and the longitudinal linings 4 can also be distributed at an oblique angle α relative to the horizontal plane. In other other embodiments, the above-mentioned outermost transverse linings 3 and the longitudinal linings 4 perpendicular to the horizontal plane can also be replaced by rolling strips. In this case, the rolling strips around the outermost side of the duvet will be perpendicular to the horizontal plane, while the other longitudinal linings 3 and the transverse linings 4 are distributed at an oblique angle α relative to the horizontal plane.

[0045] Furthermore, if Figure 5-6 As shown, in order to allow the transverse lining 3 and the longitudinal lining 4 to interpenetrate each other, so that the transverse lining 3 and the longitudinal lining 4 are relatively fixed and multiple filling cavities 6 are formed, multiple openings 7 are opened in parallel at an oblique angle α on each transverse lining 3, and similarly, multiple openings 7 are opened in parallel at the same angle as the oblique angle α of the transverse lining 3 on each longitudinal lining 4. The openings 7 are small slits, for example, openings cut obliquely by scissors. By respectively providing multiple parallel slit openings with the same oblique angle α as the longitudinal and transverse linings on the transverse lining and the longitudinal lining, the longitudinal lining and the transverse lining can be closely interpenetrated with each other. Among them, the length of the openings 7 satisfies:

[0046] Said

[0047] Said

[0048] Preferably, along the opening direction, at the same opening position, the unopened length of the horizontal lining 3 is equal to the opening length of the vertical lining 4, which is the most suitable. Of course, due to the small opening gap, the horizontal lining 3 and the vertical lining 4 can be closely interlaced, and the length of the opening can also make the lengths of multiple openings of the vertical and horizontal linings the same. The filling space of the duvet of the present invention can include 5 to 9 columns of longitudinal filling cavities and 6 to 10 rows of transverse filling cavities, the length of the filling opening is 2.5 to 4 cm, the vertical lining spacing is 24.8 to 33 cm, and the horizontal lining spacing is 24.5 to 33 cm. The filling material in the filling cavity can be duck down or goose down.

[0049] In addition, regarding the oblique angle α, the present invention refers to an acute angle less than 90°. Preferably, the oblique angle α is 30-40°. By placing and sewing the horizontal lining and the vertical lining at an oblique angle of 30-40°, the filling space of the duvet is divided into a plurality of filling cavities with rectangular upper and lower bottoms and parallelograms or right-angled trapezoids on the sides. The selection of the angle is a preferred angle obtained through experiments and calculations. If the oblique angle is too large, the inclination angle of the horizontal lining and the vertical lining in the filling space will increase accordingly, and the down barrier effect cannot be achieved; if the oblique angle is too small, the horizontal lining and the vertical lining will compress the down in the filling space, reduce the air volume, and deteriorate the warmth retention. The present invention not only provides relatively sufficient space for the down to have a better fluffiness, but also prevents the down in each filling cavity from gathering from the corners to the middle because of the oblique angle design, ensuring that the overall filling of the duvet is uniform, thereby enhancing the warmth retention of the duvet.

[0050] In addition, the present invention also provides a method for processing the duvet as described above, comprising the following steps:

[0051] S1, cutting an appropriate number of horizontal linings 3 and vertical linings 4, and the sizes of the horizontal linings 3 and vertical linings 4 are adapted to the sizes of the face 1 and the lining 2 respectively;

[0052] S2, multiple openings 7 are opened in parallel with multiple horizontal linings 3 and multiple vertical linings 4 at a certain interval according to the oblique angle α, Said

[0053] S3. Place multiple horizontal liners 3 in parallel at a certain interval, and insert multiple vertical liners 4 along their openings into the openings of multiple horizontal liners 3 in the same longitudinal direction, or place multiple vertical liners 4 in parallel at a certain interval, and insert multiple horizontal liners 3 along their openings into the openings of multiple vertical liners 4 in the same horizontal direction, so that multiple hexahedral filling cavities 6 are formed between the multiple horizontal liners 3 and the multiple vertical liners 4; preferably, the upper and lower bottom surfaces of the hexahedral filling cavities 6 in this embodiment are rectangular, and the side surfaces are parallelograms or right-angled trapezoids; in addition, when the horizontal liners 3 and the vertical liners 4 are interlaced with each other, the opening positions on the horizontal liners 3 and the vertical liners 4 are opposite, that is, the opening position of the horizontal liners 3 is located on the side where the horizontal liners 3 and the vertical liners 4 are interlaced, and the opening of the vertical liners 4 is located on the side where the vertical liners 4 and the horizontal liners 3 are interlaced.

[0054] S4, cover the top of the horizontal lining 3 and the vertical lining 4 with the top 1, and sew the shorter side of the horizontal lining 3 and the vertical lining 4 with the top 1 in order from short to long, and then sew the longer side with the top 1, and complete the sewing of all the horizontal linings 3 and the vertical linings 4 with the top 1 in sequence;

[0055] S5, cover the lower ends of the horizontal lining 3 and the vertical lining 4 with the lining 2, and sew the shorter side of the horizontal lining 3 and the vertical lining 4 with the lining 2 in the order from short to long, and then sew the longer side with the lining 2, and when sewing the horizontal lining 3, leave an opening 7 of 2.5 to 4 cm at the side of the vertical lining 4 adjacent to the filling cavity 6 as the filling port 5, and sew all the horizontal linings 3 and the vertical lining 4 with the lining 2 in sequence, and the filling port 5 and the filling cavity 6 in the same longitudinal direction form a filling channel;

[0056] S6, sewing the two longitudinal sides and one transverse side of the duvet with the facing strip, and then directly pressing the lining 2 onto the rolling strip to complete the sewing of the three sides of the duvet;

[0057] S7, extending the filling tube into the filling channel, and moving it to the innermost filling cavity 6 to fill the filling, and then moving it back to the next filling cavity 6 in the same longitudinal direction, and filling the filling cavities 6 in the same longitudinal direction in turn;

[0058] S8, moving to the next filling channel, and filling the filling cavities 6 in other longitudinal directions according to the previous step. After the filling tube has filled the filling cavities 6 through all the filling channels, the filling of the down quilt is completed;

[0059] S9, the unsewn transverse edges of the face 1 and the lining 2 are pressed and sewn together, and the down quilt is completed.

[0060] The present invention exemplarily provides an oblique angle staggered reinforced thermal insulation duvet with a specification of 2m*2.3m. The duvet includes a cover 1, a lining 2, a plurality of horizontal linings 3 and a plurality of vertical linings 4.

[0061] Specifically, the outer layer 1 and the inner layer 2 are arranged at intervals, and a filling space is formed between the outer layer 1 and the inner layer 2. The plurality of horizontal linings 3 and the plurality of vertical linings 4 are all in the shape of long strips, with a height of 4 cm, and the horizontal linings 3 and the vertical linings 4 are provided with a plurality of openings in parallel at an oblique angle of α=39°.

[0062] The horizontal linings 3 are placed at intervals in the horizontal direction, and each opening of the vertical lining 4 is inserted into the openings of multiple horizontal linings 3 in the same longitudinal direction at an oblique angle of 39°, thereby passing through all the horizontal linings 3. Figure 2 It can be seen that the vertical lining 4 and the horizontal lining 3 are interlaced and stitched between the face 1 and the lining 2 at an oblique angle of 39°, dividing the filling space into a number of hexahedrons with rectangular upper and lower bases and parallelograms or right-angled trapezoids on the sides.

[0063] The horizontal lining 3 and the vertical lining 4 can be made of a slightly harder cloth material. The upper end of the horizontal lining 3 and the upper end of the vertical lining 4 are sewn to the cover 1, and the lower end of the horizontal lining 3 and the lower end of the vertical lining 3 are sewn to the lining 2. The multiple hexahedral cavities formed are all filling cavities 6. The three-dimensional grid can ensure the fluffiness of the duvet. Figure 3 As shown, the filling cavity 6 can be filled with down such as white goose down, grey goose down, white duck down or grey duck down. The following table lists the relevant data of the filling cavity after the horizontal and vertical linings in the filling space of the 2m×2.3m and 2.2m×2.4m duvets are divided at an oblique angle of 39 degrees.

[0064] Table 1 Down quilt filling cavity size table

[0065] 2m×2.3m 2.2m×2.4m Vertical grid number 7 grid 8 grid Horizontal grid number 8 grid 9 grid Length of upper side of horizontal trapezoid 24.5cm 25cm Length of lower side of horizontal trapezoid 33cm 30cm Length of the upper side of the longitudinal trapezoid 24.8cm 24.8cm Length of lower side of vertical trapezoid 33cm 29cm Length of the parallelogram side 28.5cm 27.5cm Length of the parallelogram side 28.7cm 26.6cm

[0066] Furthermore, if Figure 4 As shown, the horizontal lining has multiple unstitched sections on both sides of the vertical lining of the adjacent filling cavity as filling openings 5, and only one filling opening is left in the same filling cavity. The filling opening 5 is connected with the corresponding filling cavity 6 to form a filling channel in the same longitudinal direction. The maximum width of the filling opening is 4 cm, so that the filling tube can enter the duvet along the filling channel to fill the down into each filling cavity 6, which not only ensures that the down is evenly distributed in the filling space of the duvet, but also avoids the mutual flow of down as much as possible.

[0067] On the other hand, the present invention discloses a specific processing method of the down quilt as described above, which specifically comprises the following steps:

[0068] Cut an appropriate number of horizontal linings 3 and vertical linings 4, and the sizes of the horizontal linings 3 and vertical linings 4 are adapted to the sizes of the face 1 and the lining 2; open multiple openings in parallel at an angle of 39° at intervals of the corresponding quadrilateral side lengths listed in Table 1 on multiple horizontal linings 3 and multiple vertical linings 4, and the horizontal opening length is The longitudinal opening length L' is the same as L; a plurality of transverse liners 3 are placed in parallel at a certain interval, and a plurality of longitudinal liners 4 are respectively inserted into the openings of a plurality of transverse liners in the same longitudinal direction along their openings, so that a plurality of hexahedral filling cavities 6 with rectangular upper and lower bases and parallelogram or right-angled trapezoidal sides are formed between the plurality of transverse liners 3 and the plurality of longitudinal liners 4;

[0069] Cover the top 1 on the upper end of the horizontal lining 3 and the vertical lining 4, and sew the shorter side of the horizontal lining 3 and the vertical lining 4 to the top in order from short to long, and then sew the longer side to the top, and complete the sewing of all the horizontal linings 3 and the vertical lining 4 to the top in sequence; Cover the bottom 2 on the horizontal lining 3 and the vertical lining 4, and sew the shorter side of the horizontal lining 3 and the vertical lining 4 to the lining in order from short to long, and then sew the longer side to the top. Sewing with the lining; when sewing the horizontal lining 3, a 3 cm opening is left at both sides of the vertical lining of the adjacent filling cavity 6 as a filling opening, and each filling cavity 6 has only one opening, so as to complete the sewing of all the horizontal linings 3 and the vertical lining 4 with the lining in sequence, and the filling opening 5 in the same longitudinal direction and the corresponding filling cavity 6 form a filling channel; sew the two longitudinal sides and one horizontal side of the duvet with the rolling strip, and then directly press the lining on the rolling strip to complete the sewing of the three sides of the duvet;

[0070] The filling tube is inserted into the filling channel and moved to the innermost filling cavity 6 for filling, and then moved back to the next filling cavity in the same longitudinal direction, and the filling cavities 6 in the same longitudinal direction are filled with down in turn; it is moved to the next filling channel, and the filling cavities 6 in other longitudinal directions are filled with down according to the previous step. After the filling tube has filled the filling cavities 6 through all the filling channels, the filling of the down quilt is completed; finally, the face and lining at the unsewn transverse edges are pressed and sewn together, and the down quilt is completed.

[0071] As can be seen from the above, the present invention divides the filling space of the duvet into multiple filling cavities with rectangular upper and lower bottoms and parallelogram or right-angled trapezoidal sides by placing and sewing the transverse lining and the longitudinal lining at an oblique angle of 30 to 40 degrees. The angle is a preferred angle obtained through experiments and calculations. If the degree of the oblique angle is too large, the inclination angle of the transverse lining and the longitudinal lining in the filling space will become larger accordingly, and the down barrier effect cannot be achieved; if the degree of the oblique angle is too small, the transverse lining and the longitudinal lining will compress the down in the filling space, the air volume will be reduced, and the warmth retention will be poor. The present invention not only provides relatively sufficient space to make the down have better fluffiness, but also prevents the down in each filling cavity from gathering from the corners to the middle because of the oblique angle design, ensuring that the overall filling of the duvet is uniform, thereby enhancing the warmth retention of the duvet.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
