One-piece bottle-shaped fabric bag

Abstract

The one-piece bottle-shaped fabric bag of the present invention does not need to be realized on a complex and special loom, and can be woven on an ordinary loom. It does not require a special-shaped steel reed, and has the characteristics of high production efficiency and a wide range of adaptability when woven on the loom. The diameter-changing methods used in the preparation of the one-piece bottle-shaped fabric bag of the present invention mainly include the weft-increasing diameter-changing method and the tissue design diameter-changing method. Compared with the conventional diameter-changing method of increasing and decreasing warp yarns, the weft-increasing diameter-changing method has the adjustability of diameter change. The diameter of the tubular fabric is changed by changing the weft yarn while the warp yarn remains unchanged. The diameter change rate of the weft-increasing diameter-changing method is 1 to 10 times greater than the diameter change rate of the warp yarn-increasing diameter-changing method. The tissue design diameter-changing method is a method of adjusting the fabric tissue structure to change the diameter of the tubular fabric. It can change the fabric tissue structure and tissue color shape as needed while achieving diameter change in a flexible and changeable manner.

Description

Technical Field

[0001] The invention relates to the field of fabric weaving, in particular to an integrally formed bottle-shaped fabric bag. Background Art

[0002] In daily life, there are many scenarios that require the use of variable diameter tubular bladder fabrics. The most common method is to sew or fit the fabric parts together. Although the efficiency is high, it is easy to leak at the stitched or fitted parts and the strength is insufficient. The existing methods for weaving variable diameter fabrics include hand weaving, special shaped steel reed weaving, warp yarn addition and subtraction, and special three-dimensional loom weaving. Hand weaving is extremely inefficient, and weaving on special three-dimensional looms requires high mechanical requirements and the cooperation of highly skilled personnel to complete, which greatly increases the cost of variable diameter tubular fabrics. Alternatively, the variable diameter tubular fabrics achieved by using special looms and special shaped steel reeds are more complex, require high technical requirements, and have low production efficiency. The conventional warp yarn addition and subtraction variable diameter method cannot adjust the diameter parameters according to needs, has a low diameter change rate, and has a small scope of application. While the diameter change method has been developed, the technology for forming tubular bladder fabrics in one step has not been solved. Therefore, there is an urgent need to develop a bladder fabric that can achieve diameter change and can be integrally formed with a bottom seal. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an integrally formed bottle-shaped fabric bag in view of the above shortcomings.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An integrally formed bottle-shaped fabric bag comprises, from top to bottom, a bottle mouth area, a bottle neck area, a bottle body area, and a bottle bottom area. The bottle mouth area, the bottle body area, and the bottle bottom area adopt a plain tubular weave structure. The bottle neck area adopts a weft increasing and diameter changing method to gradually increase the diameter of the fabric bag without changing the fabric weave. The bottle bottom area adopts a zoned contraction method to be divided into multiple areas from top to bottom, and each area adopts a different weave structure to gradually reduce the transverse diameter of the fabric bag and complete the closing.

[0006] Furthermore, weaving was performed on an automated loom, and the 16-page heald frame was divided into four parts: 13-16 pages, 9-12 pages, 5-8 pages, and 1-4 pages, corresponding to areas a, b, c, and d in the bottle bottom area, respectively.

[0007] Furthermore, the bottle bottom area is divided into areas a, b, c and d from top to bottom, and the designed length-to-width ratios of areas a, b, c and d are (1-2): (3-4): (5-7): (9-11); and the width ratios are (1-1.5): (2-2.5): (3-3.5): (4-4.5).

[0008] Furthermore, in area a of the bottom area of ​​the bottle, the warp yarns and weft yarns on pages 13 to 16 are woven in a single-layer plain weave, and the warp yarns on pages 9 to 12, pages 5 to 8, and pages 1 to 4 are kept in a double-layer plain weave pattern; in area b, the warp yarns and weft yarns on pages 13 to 16, pages 9 to 12 are woven in a single-layer plain weave, and the warp yarns on pages 5 to 8, and pages 1 to 4 are kept in a double-layer plain weave pattern; in area c, the warp yarns and weft yarns on pages 13 to 16, pages 9 to 12, pages 5 to 8 are woven in a single-layer plain weave, and the warp yarns on pages 1 to 4 are kept in a double-layer plain weave pattern; in area d, pages 13 to 16, pages 9 to 12, pages 5 to 8, and pages 1 to 4 are woven in a single-layer plain weave pattern.

[0009] Furthermore, the bottle mouth area, the bottle neck area and the bottle body area are composed of two layers of plain weave, one above and one below.

[0010] Furthermore, fine weft yarns are used to interweave with warp yarns in the bottle mouth area. When the weaving of the bottle mouth area is completed, coarse weft yarns are used to interweave with warp yarns to start weaving the bottleneck area. The bottleneck area, bottle body area and bottle bottom area keep the coarse weft yarns and warp yarns interwoven.

[0011] Furthermore, the linear density of the fine weft yarn is 14-18 tex, and the linear density of the coarse weft yarn is 120-160 tex. After adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0012] The one-piece bottle-shaped fabric bag of the present invention does not need to be realized on a complex and special loom, and can be woven on an ordinary loom. It does not require a special special-shaped steel reed, and has the characteristics of high production efficiency and a wide range of adaptability when woven on the loom. The diameter-changing method used in the preparation of an one-piece bottle-shaped (special-shaped) fabric bag of the present invention mainly includes a weft-increasing diameter-changing method and a tissue design diameter-changing method. The weft-increasing diameter-changing method and the conventional diameter-changing method of increasing and decreasing warp yarns have the controllability of diameter-changing. The caliber of the tubular fabric is changed by changing the weft yarn while the warp yarn remains unchanged. The diameter-changing rate of the weft-increasing diameter-changing method is 1 to 10 times greater than the diameter-changing rate of the diameter-changing method of increasing and decreasing warp yarns. The tissue design diameter-changing method is a method of adjusting the fabric tissue structure to change the caliber of the tubular fabric. It can change the fabric tissue structure and tissue color shape as needed while achieving diameter change in a flexible and changeable manner.

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "fine special weft yarn" and "coarse special weft yarn" are used in contrast to each other. Since the present invention patent mentions the method of changing weft and diameter, it specifically refers to the change of weft yarn. The terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0019] The main steps of preparing the bottle-shaped (special-shaped) fabric capsule and the preparation method thereof of the present invention are as follows:

[0020] (1) Selecting suitable yarns as the warp and weft yarns of the bottle-shaped (special-shaped) fabric bag;

[0021] (2) Design the size and parameters based on the bottle-shaped (special-shaped) fabric bag weaving model;

[0022] (3) Place the weft on the machine according to the number of warp yarns inserted into the reed and start weaving from the bottle-shaped (special-shaped) opening section.

[0023] like Figure 1-3 As shown in the figure, during weaving, the bottle-shaped (special-shaped) fabric bag is divided into four areas: the bottle mouth area (A), the bottleneck area (B), the bottle body area (C), and the bottle bottom area (D). Area A uses fine special weft yarns interwoven with the warp yarns, while Areas B, C, and D use coarse special weft yarns interwoven with the warp yarns. Area A is composed of fine special weft yarns interwoven with the warp yarns, forming a compact tubular structure with a small diameter. Area B is the next area after Area A, also known as the diameter-changing area using the weft-increasing and diameter-changing method. Coarse special weft yarns are interwoven with the warp yarns to create the diameter-changing effect. Area C is the connecting area after the diameter change in Area B, and the diameter of Area C is characterized by its stable characteristics. The diameter change of zone D is achieved through the tissue design diameter change method, which divides zone D into four parts: zone a, zone b, zone c and zone d. In order to achieve the diameter change effect, the tissue diagrams of different areas are designed differently, with length ratios of (1-2):(3-4):(5-7):(9-11); width ratios of (1-1.5):(2-2.5):(3-3.5):(4-4.5).

[0024] Key design points for on-the-job operation

[0025] 1. Drawing in

[0026] A 16-page heald frame is selected, and the heald drawing adopts a composite superposition method of the forward drawing method and the flying drawing method. The drawing-in order is 13 pages-16 pages, 9 pages-12 pages, 5 pages-8 pages, 1 page-4 pages, 1 page-4 pages, 5 pages-8 pages, 9 pages-12 pages, and 13 pages-16 pages.

[0027] 2. Pattern design

[0028] In order to realize the bottom area of ​​the bottle, the upper and lower inner layers are interwoven at the two ends of the bottle body, while the middle part maintains the upper warp and weft interweaving and the lower warp and weft interweaving without interfering with each other. This unique method realizes that one weft yarn is interwoven with multiple warp yarns synchronously and the different fabric inner and outer layers are linked in a way that gradually realizes the diameter change.

[0029] Example 1

[0030] Step 1: Select 65\35 polyester-cotton blended yarn as the yarn, with the warp yarn being 16tex and the weft yarn being 16tex and 160tex;

[0031] Step 2: Design the size and parameters of the one-piece bottle-shaped (special-shaped) fabric bag;

[0032] Step 3: Select a steel reed with a reed number of 80

[0033] Step 4: Based on the design dimensions of the integrally formed bottle-shaped (special-shaped) fabric bag, further calculate the diameter ratio and correct the weaving parameters;

[0034] Step 5: Install the designed drawing-in sequence and draw in 13-16 pages as a cycle for 3 times, draw in 9-12 pages as a cycle for 5 times, draw in 5-8 pages as a cycle for 7 times, draw in 1-4 pages as a cycle for 20 times, draw in 5-8 pages as a cycle for 7 times, draw in 9-12 pages as a cycle for 5 times, and draw in 13-16 pages as a cycle for 3 times;

[0035] Step 6: Insert 4 reeds into one reed;

[0036] Step 7: Select the pattern of the plain tubular fabric and start weaving the area A of the overall design drawing with the opening end of the integrally formed bottle-shaped (special-shaped) fabric bag as the starting end. In this area, 65\3516tex polyester-cotton blended yarn is selected as the warp and weft yarns, and the diameter is kept constant until the area A is completed;

[0037] Step 8: Weaving of area B, using the pattern pattern and the pattern pattern of area A Figure 1Then, 65\35 160tex polyester-cotton blended yarn is used as the weft yarn and the beating-up weaving is performed at a constant beating-up force until the diameter of the integrally formed bottle-shaped (special-shaped) fabric bag no longer changes, that is, the weaving of area B is completed;

[0038] Step 9: Weaving in area C is carried out according to the design length requirements with a constant beating force until the requirements are met;

[0039] Step 10: To weave the D area, first change the pattern pattern and select the pattern pattern of area a to beat the weft with a constant beating force to complete the weaving of area a, then select the pattern pattern of area b to beat the weft with a constant beating force to complete the weaving of area b, then select the pattern pattern of area c to beat the weft with a constant beating force to complete the weaving of area c, and finally select the pattern pattern of area d to beat the weft with a constant beating force to complete the weaving of area d.

[0040] In the preparation method of the integrally formed bottle-shaped (special-shaped) fabric bag of this embodiment, the diameter change refers to the part of the fabric with a changed transverse diameter, wherein the two diameter change parts are presented in a substantially symmetrical form as shown in FIG. Figure 1 The second part of the variable diameter, namely the D area, presents a four-part variable diameter weaving area to complete the preparation of the one-piece bottle-shaped (special-shaped) fabric bag.
