Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a fabric cutting process method. Background Technology

[0002] In the process of cutting multi-layered fabrics, the vacuum adsorption effect plays a decisive role in the cutting quality, efficiency, and precision. However, in many industries such as seating, bags, outdoor products, and down clothing, many fabrics are non-breathable. During vacuum adsorption, the top layer of fabric in a multi-layered structure may not be firmly adsorbed, leading to fabric shifting during cutting and causing accidents. This is especially true for down jacket fabrics, which are lightweight, thin, smooth, and non-breathable, making cutting problems particularly prominent. Cutting non-breathable fabrics has always been a major challenge in the multi-layered fabric cutting industry. Traditionally, cutting non-breathable fabrics requires continuous manual air replenishment. This involves the cutting operator covering the seam with a thin film after cutting to maintain the vacuum adsorption effect and prevent fabric shifting. Multiple air replenishment operations are cumbersome, wasteful of labor, and inefficient. Furthermore, the cutting table is running during each manual air replenishment operation, making repeated manual replenishment dangerous. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a fabric cutting process that can cut non-breathable fabrics and only requires one air replenishment operation.

[0004] To address the aforementioned technical problems, the present invention provides a fabric cutting process method, comprising the following steps:

[0005] 1) Complete the production of the cutting pattern; on the cutting pattern, the gap between the outlines of adjacent pieces is the waste material area, and the punching positions are set in the waste material area;

[0006] 2) Lay out multiple layers of fabric;

[0007] 3) Transfer the laid-out multi-layered fabric to the cutting area of ​​the cutting table;

[0008] 4) Lay the cutting pattern on the multi-layered fabric;

[0009] 5) Cover the multi-layer fabric with a first vacuum film, with the first vacuum film above the cutting pattern, and perform an air extraction operation on the bottom of the multi-layer fabric to complete the vacuum adsorption of the multi-layer fabric.

[0010] 6) Punch holes in the multi-layer fabric according to the preset punching positions of the waste section;

[0011] 7) Cover the first vacuum membrane of the multi-layer fabric with a second vacuum membrane, and perform an air extraction operation on the bottom of the multi-layer fabric to complete the vacuum adsorption of the multi-layer fabric.

[0012] 8) Perform piece cutting operations on multi-layered fabrics;

[0013] 9) Transport and collect the cut pieces.

[0014] Preferably, in step 6), a pin-type punching device is used to punch holes in the multi-layer fabric.

[0015] Preferably, the top surface of the cutting pattern has a marking section inside the outline of the cut piece.

[0016] Preferably, in step 6), a punching drill of a punching device is used to punch holes in the multi-layer fabric, and the air outlet of a cold air gun is directed towards the punching drill. While the punching drill is punching holes in the multi-layer fabric, the cold air gun blows cold air onto the punching drill.

[0017] As described above, the fabric cutting process of the present invention has the following beneficial effects:

[0018] The fabric cutting process of this invention requires the pre-setting of a cutting pattern before cutting the fabric. On the cutting pattern, the gaps between the cut pieces are designated as waste areas, and perforation positions are set within these waste areas. After a first vacuum film is applied to multiple layers of fabric to create vacuum adsorption, perforations are made in the waste areas according to the pre-set perforation positions. This creates breathable holes around each layer of fabric, maximizing the conversion of non-breathable fabric into breathable fabric and improving the adsorption effect. This fabric cutting process only requires covering the fabric with a second vacuum film after perforation, meaning only one air replenishment operation is needed after the perforation process. This significantly reduces labor, improves efficiency, and eliminates the need for air replenishment during the cutting process, enhancing the safety of the cutting process.

[0031] like Figure 1 and Figure 2 As shown, the fabric cutting process method of this embodiment includes the following steps:

[0032] 1) Complete the production of the cutting pattern; on the cutting pattern, the gap between the outlines 110 of adjacent pieces is the waste material section 120, and the punching position 130 is set in the waste material section 120;

[0033] 2) Lay out multiple layers of fabric;

[0034] 3) Transfer the laid-out multi-layered fabric to the cutting area of ​​the cutting table;

[0035] 4) Lay the cutting pattern on the multi-layered fabric;

[0036] 5) Cover the multi-layer fabric with a first vacuum film, with the first vacuum film above the cutting pattern, and perform an air extraction operation on the bottom of the multi-layer fabric to complete the vacuum adsorption of the multi-layer fabric.

[0037] 6) Punch holes in the multi-layer fabric according to the preset punching positions 130 of the waste section 120, that is, punch holes in the multi-layer fabric according to all the preset punching positions 130 of the waste section.

[0038] 7) Cover the first vacuum membrane of the multi-layer fabric with a second vacuum membrane, and perform an air extraction operation on the bottom of the multi-layer fabric to complete the vacuum adsorption of the multi-layer fabric.

[0039] 8) Perform piece cutting operations on multi-layered fabrics;

[0040] 9) Transport and collect the cut pieces.

[0041] The fabric cutting process of this invention requires a pre-set cutting pattern before cutting the fabric. On the cutting pattern, the gaps between the outlines 110 of the cut pieces are designated as waste material portions 120, and perforation positions 130 are set within these waste material portions 120. In multi-layered fabrics, the cutting pattern is laid on the top layer. After a first vacuum film is covered over the multi-layered fabrics to create a vacuum, perforation is performed on the waste material portions 120 according to the pre-set perforation positions 130. This ensures that each layer of fabric has breathable holes around its cut pieces, maximizing the conversion of non-breathable fabric into breathable fabric and improving the adsorption effect. This fabric cutting process only requires covering the multi-layered fabric with a second vacuum film after perforation, meaning only one air replenishment operation is needed after the perforation process. This reduces labor, increases efficiency, and eliminates the need for air replenishment during the cutting process, improving safety.

[0042] This fabric cutting technique is applicable to non-breathable fabrics, including down jacket fabrics, bag fabrics, outdoor clothing fabrics, and seating fabrics. For down jacket fabrics, which are among the most difficult to cut, this technique can increase the number of layers from 60 to 110, an improvement of over 80%.

[0043] During the fabric spreading process of down jackets, a small amount of air will be trapped between the fabric layers. The perforation process is to remove this small amount of air from the fabric layers and increase the adsorption effect between the fabric layers.

[0044] In step 6), a pin-type punching device is used to punch holes in the multi-layered fabric. The pin-type punching device passes through the first vacuum membrane, the cutting pattern, and the multiple layers of fabric sequentially from top to bottom to punch holes in the fabric. The pin-type punching device can pass through multiple layers of fabric and quickly complete the punching operation.

[0045] On the top surface of the cutting pattern, there is a marking portion 140 inside the outline 110 of the cut piece. After the cut piece cutting operation is performed on the multi-layer fabric, since the top surface of the multi-layer cut piece is provided with a cutting pattern, relevant information about the cut piece can be obtained according to the marking portion 140 on the cutting pattern.

[0046] The drilling location 130 and the number of drilling holes are determined based on the area and shape of each waste section 120.

[0047] In this embodiment, both the first vacuum film and the second vacuum film are thin films. The cutting pattern is printed on the marker paper.

[0048] In step 8), the controller stores the information of the cutting pattern. Based on the cutting pattern information, the controller controls the cutting blade of the cutting bed to perform cutting operations on the multi-layer fabric.

[0049] The cutting area of ​​the cutting table is larger than the area of ​​the fabric to be cut, and the fabric to be cut is located within the cutting area of ​​the cutting table. In step 5), a first vacuum film is covered on the multi-layered fabric, and the first vacuum film covers the cutting area of ​​the cutting table. In step 7), a second vacuum film is then covered on the first vacuum film of the multi-layered fabric, and the second vacuum film covers the cutting area of ​​the cutting table. This ensures that the vacuum adsorption of the multi-layered fabric is completed in steps 5) and 7).

[0050] Because the fabrics cannot stick together during punching, otherwise the small amount of air between the fabrics cannot escape, and the punch drill will heat up after multiple punches, using a heated punch drill will cause the fabrics to stick together. In step 6), the punch drill 200 of the punching device is used to punch multiple layers of fabric. The air outlet of the cold air gun 300 is directed towards the punch drill 200. While the punch drill 200 is punching multiple layers of fabric, the cold air gun 300 blows cold air onto the punch drill 200. The cold air released by the cold air gun 300 cools down the punch drill, preventing the fabrics from sticking together.

[0051] In summary, this embodiment effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0052] The above embodiments are merely illustrative of the principles and effects of this embodiment and are not intended to limit this embodiment. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this embodiment. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this embodiment should still be covered by the claims of this embodiment.
