Description

Woven bag

Technical Field

The utility model relates to a woven bag.

Background

People often carry satchels, handbags, etc. with them to hold small items such as paper towels, cosmetics, etc. that may need to be used at any time. The existing satchel and handbag can be made of animal skin, artificial leather, plant material fabric, nylon cloth and the like. It is well known that animal skins need to be available at the expense of life for the animal. The artificial leather has the common problem of easy aging. The plant material fabric is susceptible to damp and mildew, and therefore the service life thereof is relatively short. Nylon cloth requires synthetic chemical materials, which can cause a great deal of pollution during the preparation process. There is therefore a need to find a durable and naturally friendly material.

It is known that substances made of materials which are not easily oxidized and decomposed by nature, such as plastic bottles, plastic bags, etc., are arbitrarily discarded to flow into the sea and cause white pollution. Companies have recovered this marine white waste and produced fiber products such as marine yarns. Generally, in order to ensure the service life of a product, enterprises can weave a multi-layer structure woven fabric by using the ocean yarns, and then manufacture related products. This causes a problem that the fabric having the multi-layer structure is not easily bent, and a worker needs to expend efforts to bend the fabric and hold it at a bent position before sewing. For making small and bulky bag-like products such as satchels and handbags, workers need to expend more effort to make the products.

Another characteristic of marine yarns is that they have excellent extensibility. After a certain tensile force is applied, the woven fabric made of the ocean yarns is easy to elongate, so that the marine yarn is only suitable for manufacturing products which cannot bear large tensile force, such as shoes. Satchels, handbags and the like need to be placed with various substances, and therefore can bear various tensile forces, and woven fabrics made of ocean yarns are not suitable for making the bags.

Detailed Description

The inventive concept will be described in detail below with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention. In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "vertical", and the like, are used with reference to the orientation as illustrated in the drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.

Fig. 1, 2 show an exemplary woven bag according to the invention from different angles. As shown in fig. 1 and 2, the woven bag is manufactured by a fly-weaving technique. The woven bag includes a body portion and handles, straps, etc. secured to the body portion. The main body part defines a placing space for placing various articles in the woven bag. Alternatively, a built-in pouch may be attached within the body portion, as shown in fig. 2.

The main body of the utility model is composed of a main body sheet which is woven by a fly-weaving machine at one time. Specifically, the main body sheet is subjected to bumping and bending, and then is directly seamed to form a predetermined shape of the bag. The main body sheet is of a multi-layer sheet structure, and the number of fabric layers of at least one part of the bending area of the main body sheet is less than that of the other areas of the main body sheet. Thus, the body sheet is easily bent at the desired bending region to form corner portions of the bag, and the body sheets adjacent to the corner portions can be sewn together by a worker. In the woven bag thus produced, the portion having a small number of fabric layers does not receive tensile force or the like, and therefore the woven bag can receive a large tensile force or the like.

The body sheet is preferably woven from nylon thermal fuse and sea yarn, which is a sheet-like fabric having a predetermined shape. The marine yarn is made of white garbage flowing into the sea, such as plastic bottles, which is a conventional material in the field and will not be described herein.

In order to use the marine yarn as a woven bag for manufacturing the present invention, the applicant weaves the nylon thermal fuse and the marine yarn in an interlaced manner. Advantageously, the denier T of the marine yarn used to make the body sheet_d1Set to 120D (Denier), … 130D, … 150D, … 180D, etc.; the twist T is set to 32F,. 36F, … 40F, etc.

Nylon thermal fuse as monofilament having fineness T_d2Preferably 80D,. 100D, … 110D, etc., with diameters set to 0.12mm, … 0.15mm, … 0.18mm, etc.

Most preferably, the denier T of the marine yarn_d1Set to 150D, twist T to 36F; fineness T of nylon thermal fuse_d2Set to 90D or 100D, diameter set to 0.15 mm; the number of strands of the marine yarn is set to 4; the nylon thermal fuse was set to 2 strips. In this case, the woven bag formed by weaving 4 strands of the marine yarn of the above-described type and the nylon thermal fuse has a relatively good setting effect and retains a soft touch.

Figure 3 shows a body sheet, generally in the shape of a cross, used to make the body portion of the woven bag shown in figures 1 and 2. To facilitate the illustration of different fabric layers at different locations on the body sheet, fig. 3 shows the fold areas with a smaller number of fabric layers by means of thick lines, and thin lines to define the boundaries of the body sheet and of the motif on the body sheet.

In the body sheet of the cross shape shown in fig. 3, a middle square frame area ABB 'a' defined by a thick line constitutes the bottom of the woven bag; the left protruding part (the part containing ACC 'A') and the right protruding part (the part containing BDD 'B') of the area respectively form the front surface and the back surface of the woven bag; the upper and lower projecting portions of this region constitute the width-directional sheets of the woven bag, respectively. It will be appreciated that in this view, the direction of extension of the left and right side projections along the Y axis is the length direction of the woven bag, and the direction of extension along the X axis is the height direction of the woven bag. The direction of extension of the upper and lower protruding portions (portions above a 'B' and below AB) along the X-axis is considered to be the "transverse direction", i.e., the thickness direction of the woven bag.

In the following, the side of the body sheet shown in fig. 3 facing the viewer is used as the outer side (top sheet) of the woven bag, and the side facing away from the viewer is used as the inner side (bottom sheet) of the woven bag. Referring to fig. 3 in conjunction with fig. 1 and 2, the left and right protruding portions and the upper and lower protruding portions of the middle square frame area are respectively bent inward and the corresponding positions are sewn to form the main body of the woven bag.

Referring to the direction of fig. 3, the body sheet is woven from bottom to top along the Y-axis. The body sheet of fig. 3 forms longitudinal hinge regions AA ', BB' extending in the length direction of the bag at two bottom hinge positions, respectively, where the bag is to be formed, and similarly forms CC ', DD' at two top hinge positions, respectively. The longitudinal turning areas AA ', BB', CC 'and DD' form the longitudinal turning areas, and the number of fabric layers of the longitudinal turning areas is less than that of the fabric layers in the non-bending areas of the main body sheet.

In addition, the body sheet also forms lateral hinge regions a 'B', AB extending in the thickness direction of the bag at two fold locations that will form the bottom and/or top of the bag, respectively. Similarly, the transverse transition regions a 'B', AB constitute transverse transition regions having fewer layers of fabric than other portions of the body sheet.

The following describes the special design of the present invention in each bending region with reference to other drawings. Wherein in each figure

Showing the loops of the purl stitch,

a positive needle stitch is shown,

four flat coils are indicated, "↓" indicates a front needle plate to turn over to a rear needle plate, "↓" indicates a rear needle plate to turn over to the front needle plate, and "-" indicates an empty needle.

The knitting of the main body sheet can be realized by a flat knitting machine having a front needle plate and a rear needle plate. Wherein FIG. 4 shows a process view of the body sheet as shown in FIG. 3,

as for the longitudinal hinge regions AA ', BB', CC ', DD', in the first embodiment, they are formed by evacuating a plurality of branches so that the body sheet lacks one or more layers at the hinge regions, inside the woven bag.

For the evacuation multi-branch process, see fig. 5-6, which show a weaving principle of evacuating two branches (needles) in a two-layer fabric, which is an enlarged view of the positions in fig. 5, 6 corresponding to the areas AA ', BB', CC ', DD' and their vicinities. In the first row (refer to the row number from bottom to top in fig. 5), the yarn feeder performs knitting with four plain needles first, and changes to an empty needle 1 needle at the nth needle position, and then continues knitting with four plain needles. In the second row, the yarn nozzle also adopts four plain needles to knit to the Nth needle position, then the back needle plate turns over needles (combining the two arrows in fig. 6) to knit by adopting empty needles at the (N + 1) th needle, and then four plain needles continue to knit. In the third row, the yarn nozzle uses tuck knitting firstly, changes the position of the Nth needle to an empty needle 1 needle at the position of the Nth needle, and then continues to adopt tuck knitting. Accordingly, the fabric has a double layer structure at other positions, and the fabric layer is formed only on the surface layer at the N, N +1 st needle position, and one layer (namely, 2 bottom suction openings) is absent on the bottom layer (one layer on the inner side of the paper surface of fig. 3). As can be seen from fig. 6, by repeating the weaving in this order, the main body sheet can be formed with the folded regions AA ', BB', CC ', DD' extending in the longitudinal direction as shown in fig. 3. See region I of fig. 5, 7, respectively, for the bottom evacuation layer thus formed.

Optionally, a U is provided on the body sheet₁U₂And U₃U₄These two bending regions have a smaller number of layers of fabric. U shape₁U₂And U₃U₄Preferably, the bottom layer is left without a layer by evacuating 1. Similar machine based on 2 evacuationThat is, the N +1 th needle in the second row is changed to the four-flat knitting, so that the bending region of 1 branch can be evacuated. With reference to FIG. 7, the resulting evacuated 1-pronged U₁U₂And U₃U₄Can be considered to be in the form of only half the width of region I of fig. 7. U deviated from bending lines AA ', BB' after the main sheet is bent and formed₁U₂And U₃U₄Is used as a reference for the path of the suture and the groove for accommodating the suture. At this time U₁U₂And U₃U₄The distance from the bend lines AA ', BB' is preferably set to 2, 3, 4, 5, 6mm, etc., facilitating the alignment of the corresponding edge on area ACC 'a' with U₁U₂And U₃U₄Aligned and sewn by sutures.

For the face draw-off layer, see area II in fig. 8 (i.e. EE ', FF' of fig. 3), the front needle board is turned over to the rear needle board and then reverse knitting is used when knitting to the corresponding row to be bent. The knitting principle is basically similar to that of the bottom evacuation layer, and the difference is that a purl needle is adopted at the Nth needle position of the second row (in combination with the figure 5). The difference between the surface evacuation layers EE ', FF' and the bottom evacuation layer is that recesses are formed in the surface layer and the bottom layer, respectively, so that the main sheet is bent in different directions.

Fig. 5-8 illustrate the weaving principle of evacuating one or both of the two legs in the face or bottom layer of the woven fabric structure (i.e., the bottom evacuated layer with 2 needles formed from left to right in fig. 5), it being understood that those skilled in the art can also apply this to other bending regions where more than 3, 4, etc. are evacuated, and more than 2, 3, etc. layers are evacuated based on the same principle, and the above concept is within the intended scope of the present invention.

Fig. 5-8 show how the evacuation layer in the Y-axis direction of fig. 3 is made by evacuating a plurality of branches, and the evacuation layer in the X-axis direction can be woven using the weaving principle shown in fig. 9 (surface evacuation). When it is desired to provide an evacuated layer extending in the X-axis direction (corresponding to line N, N +1 of fig. 9, i.e., region III), the nozzle is turned over at this position to knit with purl stitches (forming a face evacuated layer) as compared to knitting with four parallel needles in the adjacent row. The surface evacuation layer formed in this way can be seen in region III in fig. 10.

Furthermore, in order to form a smaller number of layers in the fold region, in the second embodiment, this region may also be woven with a single over-side, thereby enabling the body sheet to smoothly transition between differently oriented surfaces (between the horizontal and vertical planes of the base). Unlike woven regions that are evacuated to multiple extents, regions woven on one side are utilized that do not exhibit significant grooving (i.e., missing layers or underlayers) in either the face or the underlayers, and are therefore particularly useful in buckling regions where stitching is not required in the vicinity thereof.

For the over-single side, see fig. 11, when it is necessary to set the evacuation layer region IV in the over-single side form, the rear needle plate is turned over to the front needle plate, and the front needle plate and the rear needle plate are respectively woven one layer by one layer instead of being woven one layer at a time, as compared with other rows. Since the front and rear needle boards weave together in one layer, a smooth transition effect like the region IV of fig. 12 can be woven.

The above describes a plurality of weaving patterns forming a smaller number of layers in the bending zone, and in fact, according to the present invention, not all bending zones are necessarily so arranged. For example, a portion of the fold region thereof is configured such that the facing (or bottom) layer of the body sheet in that region bulges toward the outside of the bag. This type of turning region can be accomplished by a valley process.

For the valley wave process, see region V of fig. 13. When the yarn nozzle is used for weaving positions needing valley wave weaving, the front needle plate and the rear needle plate do not need to be turned over. During knitting, the needles of the yarn feeder are arranged in four plain stitches, and at the valley of knitting, the purl stitch stops working, and the purl stitch (single side) can be knitted for several turns and then is adjacent to the purl stitch, so that the surface layer (corresponding to the outside of the bag) has more stitches than the bottom layer (corresponding to the inside of the bag), thereby forming a bulged wavy structure. In this case, the face layer allows a larger amount of deformation, and thus the body sheet is more easily bent toward the bottom layer side at this position. The resulting region can be seen in fig. 14.

Another benefit of using the valley wave process is described below in conjunction with another shaped woven bag. Referring to fig. 15-17, wherein fig. 15-16 illustrate the overall construction of the bag from different perspectives, fig. 17 illustrates the body sheets that form the body portion of the woven bag of fig. 15-16. The center joining lines LL ', MM' of the vertical surfaces (i.e., the two surfaces in the thickness direction) at both ends in the longitudinal direction of the bag are bent positions by the valley wave process. The bending position is located on the surface layer (namely the surface of the woven bag close to the outer side) and is of a valley wave structure. Based on a certain restoring force provided by the marine yarns, the marine yarns in the wave-shaped structure have a tendency of restoring to an original straight shape (or an arc shape bulging towards the outer side), so that the marine yarns can drive a bottom layer positioned on the inner side of the woven bag to stretch, and the woven bag is easy to bulge towards the outer side of the woven bag in a natural state at a position where a valley wave process is manufactured. The woven bag thus produced is less prone to "collapse" after use and has a more stable shape.

With further reference to fig. 3 and 17, in order to ensure that each component line of the woven bag of the present invention is not easily pulled by the outside, the edge of the main sheet is set to be in the area of the border. Thus, various burrs can be eliminated.

Referring to fig. 18 in conjunction with fig. 1-2 and 15-16, the handle 1 of the woven bag arrangement is alternatively made from a strip 10 of a multi-layer sheet-like construction as shown in fig. 18. Specifically, the fabric in the middle region 11 of the braid 10 may be formed to have a smaller number of layers than other positions along the longitudinal center line thereof by means of the above-described evacuation of the plurality of branches. In use, the webbing 10 can be folded in half along the longitudinal centerline of the webbing 10 in the intermediate region and sewn or adhered to form the gripping portion of the handle 1 shown in fig. 1 and 2.

To further retain the shape of the handle 1, a strip of high density non-woven fabric (not shown) may be placed within the folded strip 10. The high-density nonwoven fabric has a higher hardness than the woven tape 10.

For the purpose of maintaining the shape of the bag, optionally, the bottom outer side of the woven bag of the present invention may also be provided with one or more securing straps, wherein the securing straps have a hardness greater than the hardness of the body sheet. More preferably, the fixing bands are provided in a plurality of strips, and are arranged in a crisscross and regular pattern at the bottom of the woven bag.

The process of making the first type of bag formed according to the concepts of the present invention is described below with reference to figures 1-3, respectively. The packet according to fig. 1-3 can be made in the following order:

1. the body sheet having a multilayer sheet structure shown in fig. 3 is woven at one time by an airplane loom. In this embodiment, the number of layers of fabric of the body sheet in the bending regions AA ', BB', CC ', DD' is smaller than that in the other regions. Preferably, the respective outer side portions of CC ', DD' are further provided with bending regions EE ', FF' parallel thereto, and the edge positions of the respective outer sides of the bending regions EE ', FF' are available for sewing the slide fastener. The bending areas EE ', FF' facilitate easy operation of the zipper by a user.

2. The thread ends of the upper and lower end parts of the main body sheet are cut off by picking and bumping.

3. Bending the body sheet along AA ', BB ', A ' B ', AB ' respectively so that A ' C ' fits U in FIG. 3₁U₂Upper part of the section, AC, to U in FIG. 3₁U₂The lower part of the part, B 'D', is attached to U in FIG. 3₃U₄Upper part of the part, BD, fits U in FIG. 3₃U₄A lower section of the portion whereby the body sheet forms a preliminary pattern for the bale; the folding of the body sheet along CC ', DD' forms the upper edge of the pack, whereby the body sheet is folded into the predetermined shape of the pack.

4. The adjacent edges of the body sheets are stitched to form a packet having a predetermined shape. Wherein the suture line is along U₁U₂And U₃U₄The defined path is sutured.

Alternatively, the body sheet is ironed after the bumping step, and the nylon thermal fuse is more firmly combined with the marine yarn, further maintaining the shape of the body sheet.

When a pattern is provided on the main body sheet, for example, a grid pattern shown in fig. 3, the main body sheet shown in fig. 3 may be placed in the grooves of the gauge board with marks and then ironed. By differentially ironing the respective positions of the main body sheet, the patterns are made to correspond to and be shaped at the respective marks on the gauge board. After the pattern is shaped in this way, the patterns at different positions of the folded main body sheet can be smoothly and continuously displayed as shown in fig. 1, and the processes of extra cutting and the like which are needed to realize the pattern continuity in the past are avoided.

The handle 1 portion of the woven bag can be made in the following manner:

a woven belt 10 woven at one time by a fly weaving technique is provided and the woven belt 10 is fixed to a bag, wherein the woven belt 10 has a multi-layer structure and is configured such that the number of fabric layers along its longitudinal centerline is smaller than those at other positions in its intermediate region 11, thereby enabling the woven belt 10 to be folded in half along its longitudinal centerline to form a grip portion of the woven bag.

The woven bag shown in fig. 11-13 differs from the bag shown in fig. 1-3 only in the manner of bending. Only the differences will be described below. Respectively folding 90 degrees along KK 'and GG' shown in figure 13, then bending the sheet material 90 degrees along the straight lines of H 'J' and HJ to ensure that G 'H' is attached to I 'H', K 'J' is attached to I 'J', GH is attached to IH and KJ is attached to IJ, and then sewing the bending areas to form the main body of the woven bag shown in figures 11 and 12.

Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
