Description

Technical Field

[0001] This utility model relates to the field of nylon fabric softening technology, and more specifically to a softening device for nylon 66 chemical fiber fabrics. Background Technology

[0002] In the production of synthetic fiber fabrics such as nylon 66, softening is a crucial finishing process. Its purpose is to soften and fluff the fabric through mechanical action, improving its hand feel and wearing performance. Currently, the softening devices commonly used in the industry are typically equipped with multiple softening blades, distributed on both sides of the fabric's movement path. During softening, the softening blades on both sides move closer together, transforming the originally straight fabric path into a zigzag shape.

[0003] However, the first cut the fabric makes is at a 180-degree angle, meaning the blade tip is perpendicular to the fabric. This contact method causes the weft threads to shift during softening of many types of fabrics (especially low-density fabrics), resulting in uneven fabric tension, substandard stiffness, and seriously affecting normal production. Summary of the Invention

[0004] To address the technical problems existing in the softening devices of the prior art, the first aspect of this utility model proposes a softening device for nylon 66 chemical fiber fabrics, comprising:

[0005] The fabric passes around the first guide roller and the second guide roller in sequence, forming a linear thread path between the first guide roller and the second guide roller.

[0006] The first set of softening blades is positioned on the first side of the line path;

[0007] The second set of softening blades is positioned on the second side of the line path;

[0008] The first set of softening blades includes a softening roller and at least one softening blade, and the second set of softening blades includes at least one softening blade. The softening roller is configured to be the first contact of the fabric after it passes over the first guide roller, and the contact surface between the softening roller and the fabric is located on the side of the guide line that faces the second set of softening blades.

[0009] The second set of softening blades is configured to move as a whole toward the first set of softening blades, so that the fabric contacts the softening roller and multiple softening blades in sequence, and the thread path is in a zigzag shape.

[0010] Preferably, the first set of softening blades includes a softening roller and a first softening blade, wherein the side surface of the softening roller facing the second set of softening blades is on the same plane as the tip of the first softening blade.

[0011] Preferably, the plane where the tip of the first softening knife is located is on the side of the line radially toward the second set of softening knives.

[0012] Preferably, the second set of softening blades includes a second softening blade and a third softening blade, which are connected to a linear drive component. The linear drive component is used to drive the second softening blade and the third softening blade to move to a first position or a second position along a direction perpendicular to the path.

[0013] Preferably, when the second softening knife and the third softening knife are in the first position, the tips of the first softening knife, the second softening knife and the third softening knife are located on the same plane. When the second softening knife and the third softening knife are in the second position, the fabric forms an angle of 90 to 100 degrees at the tip of the second softening knife.

[0014] Preferably, the softening roller, the first softening blade, the second softening blade, and the third softening blade are arranged in an alternating manner.

[0015] Preferably, the tips of the first softening knife, the second softening knife, and the third softening knife are constructed in a triangular shape, and the ends of the tips have rounded corners, with the angle of the tips being 60 to 80 degrees.

[0016] Preferably, the softening roller is a stainless steel round roller.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] By modifying the original softening blade into a softening roller, and offsetting the radial position of the softening roller and the guide roller, the fabric is not subjected to vertical pressure when it is softened. The gentle shearing force does not pull the warp and weft threads, keeping the fabric surface flat. The gentle treatment method maintains the original internal tension of the fabric, and the stiffness of the finished product meets the quality requirements. Attached Figure Description

[0023] Figure 4 This is a schematic diagram of the softening device of this utility model for softening fabrics. Detailed Implementation

[0024] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the existing softening device includes a yarn-feeding softening knife 21, a first softening knife 23, a second softening knife 22, and a third softening knife 24 distributed on both sides of the fabric path. The yarn-feeding softening knife 21 is above the first guide roller 11 and perpendicular to the yarn path. When the softening device softens the fabric, the yarn-feeding softening knife 21 still maintains perpendicular contact with the fabric, and the second softening knife 22 also applies pressure. The vertical impact force applied by the yarn-feeding softening knife 21 to the fabric will pull the warp and weft threads of the fabric, causing the weft yarn to be pushed out of place. The structure of the entire fabric surface becomes uneven, with some areas being tight and others loose. At the same time, the tiny rubber fragments generated during the softening process will stick directly to the fabric surface due to the huge vertical impact force, instead of being bounced off or absorbed, causing fabric contamination.

[0026] Combination Figure 3 and Figure 4 As shown, this utility model proposes a softening device for nylon 66 chemical fiber fabrics, including a first guide roller 11, a second guide roller 12, a first set of softening blades, and a second set of softening blades. The fabric passes around the first guide roller 11 and the second guide roller 12 in sequence, forming a linear thread path between the first guide roller 11 and the second guide roller 12.

[0027] The first set of softening blades is set on the first side of the line path, and the second set of softening blades is set on the second side of the line path.

[0028] The difference from the prior art is that the first set of softening knives includes a softening roller 25 and at least one softening knife, and the second set of softening knives includes at least one softening knife. The softening roller 25 is configured to be the first contact of the fabric after it passes over the first guide roller 11. The contact surface between the softening roller 25 and the fabric is located on one side of the line radially toward the second set of softening knives.

[0029] like Figure 3As shown, the leftmost side of the softening roller 25 and the rightmost side of the first guide roller 11 have a positional difference L, and are not on the same plane. Therefore, after the fabric passes around the first guide roller 11, it must move to the left and pass around the surface of the softening roller 25. This method can avoid the vertical force on the fabric surface caused by the vertical softening knife tip during the traditional softening process.

[0030] Furthermore, the second set of softening blades is configured to move as a whole toward the first set of softening blades, so that the fabric contacts the softening roller 25 and multiple softening blades in sequence, and the thread path is in a zigzag shape.

[0031] Combination Figure 4 As shown, when the second set of softening blades moves synchronously towards the first set of softening blades, the fabric is squeezed by the two sets of softening blades to form a zigzag shape. The tension is released through repeated bending, thus softening the fabric.

[0032] In a specific embodiment, the first set of softening blades includes a softening roller 25 and a first softening blade 23. The side surface of the softening roller 25 facing the second set of softening blades is on the same plane as the tip of the first softening blade 23.

[0033] Among them, the plane where the tip of the first softening knife 23 is located is on the side of the line radially toward the second set of softening knives.

[0034] Thus, when the fabric is wound out from the first guide roller 11, it can pass through the gap between the two sets of softening blades in a non-softened state.

[0035] Furthermore, the second set of softening blades includes a second softening blade 22 and a third softening blade 24. The second softening blade 22 and the third softening blade 24 are connected to a linear drive component. The linear drive component is used to drive the second softening blade 22 and the third softening blade 24 to move to a first position or a second position along a direction perpendicular to the line path.

[0036] Optionally, the linear drive component includes a lead screw drive mechanism for precisely controlling the movement position of the second set of softening blades and keeping the second set of softening blades in that position.

[0037] like Figures 3 to 4 As shown, when the second softening blade 22 and the third softening blade 24 are in the first position, the tips of the first softening blade 23, the second softening blade 22 and the third softening blade 24 are located on the same plane. When the second softening blade 22 and the third softening blade 24 are in the second position, the fabric forms an angle of 90 to 100 degrees at the tip of the second softening blade 22.

[0038] Thus, when the softening device performs softening, that is, when the second set of softening blades is driven to move to the second position, the softening roller 25, the first softening blade 23, the second softening blade 22 and the third softening blade 24 are arranged in an alternating manner. In particular, the leftmost side of the softening roller 25 limits the fabric, so that the fabric is not only not subjected to scratching action perpendicular to the fabric surface, but also the angle of the fabric contacting the second softening blade 22 is reduced, thus achieving a better softening effect.

[0039] In the above embodiments, the tips of the first softening blade 23, the second softening blade 22, and the third softening blade 24 are constructed in a triangular shape, and the ends of the blade tips have rounded corners, with the angle of the blade tips being 60 to 80 degrees. Preferably, the softening roller 25 is a stainless steel circular roller.

[0040] In conjunction with the above embodiments, by modifying the original softening knife into a softening roller, and by offsetting the radial position of the softening roller and the guide roller, the fabric is not subjected to vertical pressure when it is softened. The gentle shearing force does not pull the warp and weft threads, keeping the fabric surface flat. The gentle treatment method maintains the original internal tension of the fabric, and the stiffness of the finished product meets the quality requirements.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
