Description

Technical Field

[0001] This invention relates to the field of fabric breathability testing technology, specifically to a breathability testing device and fabric for pure natural bamboo cotton plant-dyed fabric. Background Technology

[0002] As concepts such as "low-carbon green consumption" and "sustainable development" become increasingly ingrained in consumer attitudes, plant-based dyes are gaining attention due to their unique natural advantages. Plant dyes are extracted from the roots, stems, leaves, flowers, fruits, and shells of natural plants, containing no synthetic substances and harmless to human health. The plant materials used in plant dyes undergo rigorous screening, ensuring they are not only non-toxic and harmless but also possess medicinal and health benefits. The dyeing process boasts a high dye uptake rate, generates minimal waste, has a small environmental impact, and is biodegradable, preventing persistent environmental pollution.

[0003] During the processing of this fabric, being a new material, breathability testing is required to ensure its proper use. Before testing, the fabric must be manually placed on the testing table and smoothed, which not only increases the workload of the operators but also makes it difficult to ensure the fabric remains completely flat. If wrinkles are present and not addressed, airflow will be blocked during testing, causing discrepancies between the measured breathability data and the actual breathability performance of the fabric. This results in an inaccurate reflection of the fabric's breathability quality, especially for fabrics like pure natural bamboo cotton with plant dyeing, which require high testing precision, severely impacting the reliability of the test results. Meanwhile, the transmission lines inside the existing detection devices cannot be retracted or extended. When the detector descends, the transmission lines are easily stretched due to the detector's pull, which may cause the internal wires of the transmission lines to break after long-term use, affecting the stability of data transmission. When the detector rises, if the transmission lines cannot be retracted in time, the excess transmission lines will accumulate inside the device and become entangled and squeezed with other moving parts. This will not only damage the transmission lines but may also hinder the normal movement of the parts, leading to device failure and increasing equipment maintenance costs and downtime. Summary of the Invention

[0014] A pure natural bamboo-cotton plant-dyed fabric, the processing method of which includes the following steps: Loosening the yarn → Pretreatment → Warping → Dyeing and sizing → Weaving → Greige fabric inspection → Singeing → Desizing → Setting → Pre-shrinking → Finished fabric; In the loosening step, the cylinder size is 0.5-0.6 kg / piece, and the cylinder density is 0.035-0.038 g / cm2; The pretreatment process involves modifying bamboo cotton yarn with a bio-based cationic modifier at a dosage of 1-3 g / L, a treatment temperature of 80℃, and a treatment time of 20-40 min. The dyeing and sizing steps are performed with a machine speed of 30-50 m / min, a dye liquor temperature of 55-65℃, a dye concentration of 10 g / L-50 g / L, a padding pressure of 3-5 kg, a drying temperature of 80-100℃, a sizing bath temperature of 70-90℃, a pre-drying temperature of 90-100℃, a drying temperature of 80-100℃, and a winding tension of 2200-2400 N. The fabric inspection uses the aforementioned air permeability testing device. First, the fabric is placed on top of the testing platform. Then, the flat plate is initially fixed to the fabric by the folding assembly. Next, the motor is started to drive the belt pulley to rotate, which in turn drives the moving block to move, thereby moving the right-angle rod. Through the action of the belt pulley, the movement trajectory of the right-angle rod is made into a triangular motion. First, the right-angle rod begins to move diagonally downward, which can drive the connecting plate to descend. The descent of the connecting plate drives the detector to descend. At the same time, the descent of the connecting plate, with the cooperation of the winding assembly, can unwind the connecting line to ensure the length of the connecting line. When the detector descends to the lowest point, it comes into contact with the fabric on the top of the testing platform. At this point, the right-angle bar reaches its lowest point and begins to move horizontally. During this horizontal movement, the right-angle bar, in conjunction with the moving components, allows the smoothing plate to move and smooth the fabric, thus ensuring the accuracy of the test results. After the test is completed, the results are displayed digitally on the monitor. After the test is completed, the right-angle bar begins to move diagonally upward, thereby driving the connecting plate to rise, and then driving the detector to rise. At the same time, the rising connecting plate, in conjunction with the winding components, can wind up the connecting wires to prevent the lifting plate from being squeezed and accidentally damaged during the rise. After the right-angle bar rises, the reset components can drive the smoothing plate to reset, thus preparing for the next test. When it rises to the top, the folding components can rotate the smoothing plate, thereby removing the fabric from the top of the testing table. The singeing step involves a vehicle speed of 100-150 m / min, using natural gas as the heat source, and 8-11 units of natural gas. In the desizing step, amylase is used for desizing, with an amylase dosage of 2-5 g / L, a penetrant dosage of 3-5 g / L, a machine speed of 60-80 m / min, and a heat preservation and stacking at 50-60℃ for 25-35 min. The machine is then washed twice at 80-90℃ and three times at 50-60℃.

[0015] The shaping step involves using a bio-based fatty acid softener to soften and finish the fabric.

[0016] The beneficial effects of this invention are: (1) This invention discloses a breathability testing device and fabric for pure natural bamboo cotton plant dyed fabric. In order to ensure the normal use of the material during the processing of the fabric, it is necessary to test its breathability. When testing the fabric, the breathability testing device can not only drive the detector to move up and down, but also flatten the fabric on the top of the testing platform to avoid the fabric from wrinkling and affecting the accuracy of the test. At the same time, when driving the detector to move up and down, it can retract and extend the connecting line connected to the detector to prevent the connecting line from being accidentally squeezed during the lifting process, thereby affecting the testing device and reducing the possibility of accidents involving the connecting line.

[0017] (2) The dyes and auxiliaries used in the pure natural bamboo cotton plant-dyed fabric of this invention are all bio-based. The pretreatment of the yarn packages uses a bio-based cationic modifier, the dye is a plant dye, and the finishing and softening process uses a bio-based fatty acid softener. Warp dyeing and sizing are completed in one step. After warping, the yarn is dyed by padding with the dye working solution and then dried, and then sizing is performed using the same equipment. After the weft yarn completes the dyeing process, it is then wound into packages using a reverse warping method. The dyeing process uses padding with the dye solution, ensuring that all the dye solution is absorbed without waste. No subsequent washing and color-fixing process is required. The resulting bamboo cotton plant-dyed fabric achieves a fastness of grade 4 or higher in washing, soaping, and sun exposure, and also has moisture-wicking, quick-drying, and antibacterial properties.

[0018] (3) The starting motor of the present invention can drive the moving block to move through the belt pulley, and then drive the right-angle rod to move. In the initial state, it can drive the hollow plate to descend. The descent of the hollow plate can drive the detector to descend. When the detector descends to the bottom, the two smoothing plates can move apart through the cooperation of the moving components, thereby smoothing the fabric on the top of the detection table and ensuring the accuracy of the detection. After the detection is completed, as the motor continues to run, it can drive the detector to rise. After the detector rises, the two smoothing plates can be reset through the action of the reset component, thereby preparing for the next detection.

[0019] (4) When the detector is at the lowest end, the right-angle rod is also at the lowest end. In this case, the right-angle rod can drive the moving rack plate one to move by moving. The moving rack plate one can drive the moving rack plate two to move in opposite directions through the gear one. The movement of the moving rack plate one and the moving rack plate two can drive the moving plate to move. The movement of the moving plate can drive the smoothing plate to move. The two smoothing plates move synchronously from the center of the fabric to both sides, which can not only smooth the fabric, but also ensure the stability of the fabric, thereby improving the detection effect.

[0020] (5) In this invention, when the connecting plate is raised and lowered, it can drive the teeth to rise and fall, thereby causing the active gear to rotate. The active gear, through the action of the active shaft, belt and protrusion, can drive the active bevel gear to rotate. The active bevel gear rotates and drives the passive bevel gear to rotate. The passive bevel gear, through rotation, can drive the take-up roller to rotate. The rotation of the take-up roller can take up and unwind the connecting line, preventing the connecting line from being accidentally squeezed during the raising and lowering process, thereby affecting the detection device and reducing the occurrence of accidents involving the connecting line.

[0021] (6) The present invention can also fold the flat plate and the moving plate through the function of the hinge. After the flat plate is folded, the fabric can be placed on the top of the testing table. Then the flat plate is used to initially press the fabric. Then the flat plate and the moving plate can be fixed by the action of the protrusion, clamping block two, clamping block one, fixed shaft, extrusion plate and damper. After the fabric is initially fixed, the fabric is initially processed by the action of the lifting component and the moving component. The air permeability of the fabric is tested by the detector. When the detector completes the test of the fabric, the data it obtains will be quickly transmitted to the display and presented in the form of intuitive numbers or charts. This makes it convenient for the operator to understand the air permeability of the fabric in a timely manner, effectively avoiding the adverse effects on the test results caused by the instability of the device, and improving the accuracy and reliability of the entire air permeability test.

Hinge 69 is fixed on the top of moving plate 37 and flat plate 38, providing a rotational connection between the two to realize the folding and unfolding of flat plate 38.

[0033] A pure natural bamboo-cotton plant-dyed fabric, the processing method of which includes the following steps: Loosening the yarn → Pretreatment → Warping → Dyeing and sizing → Weaving → Greige fabric inspection → Singeing → Desizing → Setting → Pre-shrinking → Finished fabric; The tube loosening process results in tubes weighing 0.5-0.6 kg each and having a density of 0.035-0.038 g / cm². In the pretreatment process, a bio-based cationic modifier is used to modify the bamboo cotton yarn. The amount of modifier is 1-3 g / L, the treatment temperature is 80℃, and the treatment time is 20-40 min. The dyeing and sizing steps are as follows: machine speed 30-50m / min, dye liquor temperature 55-65℃, dye concentration 10g / L-50g / L, padding pressure 3-5kg, drying temperature 80-100℃, sizing bath temperature 70-90℃, pre-drying temperature 90-100℃, drying temperature 80-100℃, and winding tension 2200-2400N. The above-mentioned air permeability testing device is used for the inspection of the greige fabric. First, the operator must place the greige fabric to be inspected flat on the top of the testing table 13, ensuring that the fabric is free of obvious wrinkles and shifts, laying the foundation for the accuracy of subsequent testing. Then, the fabric is initially fixed by the function of the folding component 6. The hinge 69 in the folding component 6 can flexibly adjust the angle of the flat plate 38. The operator rotates the flat plate 38 to make it fit against the fabric surface. At the same time, the synergistic action of the protrusion 66, clamping block 1 64, clamping block 2 65 and damper 68 inside the folding component 6 makes the flat plate 38 stably pressed onto the fabric: the protrusion 66 is in close contact with clamping block 1 64 and clamping block 2 65, and the damper 68 provides a stable clamping force for clamping block 2 65 through the extrusion plate 67, preventing the flat plate 38 from loosening in subsequent operations, thus completing the initial fixation of the fabric and preventing the fabric from shifting during the testing process.

[0034] After initial fixation, the motor 14 on the rear side of the starting device drives the belt pulley 31 inside the outer casing 1 to start rotating. During the rotation of the belt pulley 31, the movable block 32 fixedly connected to its outer wall moves synchronously, thereby driving the right-angle rod 33 fixedly connected to the movable block 32 to move. Due to the special structural design of the belt pulley 31, the movement trajectory of the right-angle rod 33 is limited to triangular motion. This movement trajectory can realize the functions of raising and lowering the detector 12, smoothing the fabric, and resetting the components in stages, ensuring the orderly connection of each link.

[0035] In the first stage of the triangular motion: the right-angle rod 33 moves diagonally downwards. Since the right-angle rod 33 is slidably connected inside the hollow plate 23, its diagonal downward movement generates a downward thrust on the hollow plate 23, causing it to descend vertically along the positioning rod 24. The top of the hollow plate 23 is fixedly connected to the connecting plate 22, which in turn is connected to the lifting plate 21. One side of the bottom of the lifting plate 21 is connected to the detector 12 via the lifting column 11. Therefore, when the connecting plate 22 descends with the hollow plate 23, it synchronously drives the lifting plate 21 to descend along the slide rod 25, ultimately pushing the detector 12 vertically downwards via the lifting column 11. During this process, the descent of the connecting plate 22 also triggers the linkage of the winding assembly 5: the teeth 59 fixed at the top of one side of the connecting plate 22 mesh with the drive gear 58. When the connecting plate 22 descends, the teeth 59 drive the drive gear 58 to rotate, thus promoting the rotation of the detector 12. The gear 58 drives the active bevel gear 54 to rotate synchronously through the active rotating shaft 57, belt 56 and passive rotating shaft 55. The active bevel gear 54 then drives the passive bevel gear 53 meshing with it to rotate, which in turn drives the take-up roller 51 to rotate and unwind the connecting wire 52 wound on the take-up roller 51. One end of the connecting wire 52 is fixed to the top of the lifting plate 21 and the other end is connected to the detector 12. The unwinding action ensures that the connecting wire 52 extends synchronously with the descent of the detector 12, avoiding the connecting wire 52 from breaking due to pulling. At the same time, it ensures stable data transmission between the detector 12 and external equipment. When the detector 12 descends to the lowest point, its bottom is in complete contact with the fabric on the top of the test platform 13. At this time, the test hole 15 and the fabric form a closed test space, which is ready for the air permeability test.

[0036] After the right-angle rod 33 reaches its lowest point, it enters the second stage of triangular motion: horizontal translation. During the translation, the bottom of the right-angle rod 33 abuts against the moving rack plate 34, and its horizontal movement pushes the moving rack plate 34 to slide along the slide rail inside the outer shell 1. Since the moving rack plate 34 meshes with the gear 36, and the gear 36 simultaneously meshes with the moving rack plate 35, the sliding of the moving rack plate 34 will drive the gear 36 to rotate, thereby driving the moving rack plate 35 to slide in the opposite direction. The tops of both the moving rack plate 34 and the moving rack plate 35 are fixedly connected to moving plates 37, which are connected to smoothing plates 38. Therefore, the two moving plates 37 will drive the corresponding smoothing plates 38 to move synchronously from the center of the fabric to both sides. During the movement, the smoothing plates 38 can completely smooth out any wrinkles that may exist on the surface of the fabric, ensuring that the fabric is in a completely flat state during testing, avoiding wrinkles from affecting air circulation, and thus ensuring the accuracy of the air permeability test results. During this stage, the detector 12 collects fabric breathability data through the detection hole 15 and transmits the data to the display 17 on the top of the housing 1 in real time. The display 17 displays the test results in a digital form (such as specific values ​​like air permeability and air resistance), making it convenient for operators to view and record in real time.

[0037] After the test is completed, the right-angle rod 33 enters the third stage of triangular motion: moving diagonally upwards. This movement generates an upward pulling force on the hollow plate 23, causing the hollow plate 23, connecting plate 22, and lifting plate 21 to rise synchronously. Finally, the lifting column 11 pulls the detector 12 vertically upwards, separating the detector 12 from the fabric. At the same time, the rising of the connecting plate 22 causes the teeth 59 to move in the opposite direction. Through the transmission structure of the winding assembly 5, the winding roller 51 rotates in the opposite direction to wind up the connecting wire 52. Excess connecting wire 52 is rewound onto the winding roller 51, preventing the connecting wire 52 from accumulating inside the outer shell 1 during the rising of the lifting plate 21, which could cause compression damage or affect the movement of other components.

[0038] When the right-angle rod 33 rises to the point of disengagement from the moving rack plate 34, the reset assembly 4 begins to function: one side of the reset plate 41 is fixed to the moving rack plate 34, and the other side is connected to the inside of the outer shell 1 through two reset springs 42. When the moving rack plate 34 slides during the testing phase, the reset springs 42 are in a stretched state. At this time, the reset springs 42 release elastic potential energy, pulling the reset plate 41 to move in the opposite direction along the fixed rod 43, thereby driving the moving rack plate 34, gear 36, moving rack plate 35 and moving plate 37 to reset synchronously, and finally making the flat plate 38 return to the initial position, ready for the next test. When the right-angle rod 33 rises to the top, the operator can operate the folding assembly 6 again and rotate and fold the flat plate 38 upward through the hinge 69. At this time, the fabric on the top of the testing table 13 is no longer pressed by the flat plate 38, and the operator can easily remove the tested fabric from the testing table 13. Thus, the entire fabric breathability testing process is completed. Singeing process: Vehicle speed is 100-150m / min, natural gas is used as the heat source, and the natural gas level is 8-11 bars. In the desizing step, amylase is used for desizing, with an amylase dosage of 2-5 g / L and a penetrant dosage of 3-5 g / L. The machine speed is 60-80 m / min, and the machine is kept at 50-60℃ for 25-35 min. The machine is then washed twice at 80-90℃ and three times at 50-60℃.

[0039] The finishing step involves using bio-based fatty acid softeners to soften and finish the fabric.

A pure natural bamboo-cotton plant-dyed fabric, characterized in that, The processing method for this fabric includes the following steps: Loosening the yarn → Pretreatment → Warping → Dyeing and sizing → Weaving → Greige fabric inspection → Singeing → Desizing → Setting → Pre-shrinking → Finished fabric; In the loosening step, the cylinder size is 0.5-0.6 kg / piece, and the cylinder density is 0.035-0.038 g / cm2; The pretreatment process involves modifying bamboo cotton yarn with a bio-based cationic modifier at a dosage of 1-3 g / L, a treatment temperature of 80℃, and a treatment time of 20-40 min.

The fabric inspection uses the air permeability testing device described in claim 9. First, the fabric is placed on the top of the testing platform (13). Then, the flat plate (38) is initially fixed to the fabric by the action of the folding component (6). Then, the motor (14) is started to drive the belt pulley (31) to rotate, which in turn drives the moving block (32) to move, thereby driving the right-angle rod (33) to move. Through the action of the belt pulley (31), the movement trajectory of the right-angle rod (33) is triangular. First, the right-angle rod (33) begins to move diagonally downward, which can drive the connecting plate (22) to descend. The descending of the connecting plate (22) drives the detector (12) to descend. At the same time, the descending of the connecting plate (22) can unwind the connecting line (52) through the cooperation of the winding component (5) to ensure the length of the connecting line (52). When the detector (12) descends to the lowest point, it comes into contact with the fabric on the top of the testing platform (13). At this time, the right-angle rod (33) reaches the lowest point and begins to move horizontally. During the horizontal movement, the right-angle rod (33) can move the smoothing plate (38) to smooth the fabric through the cooperation of the moving component (3), thereby ensuring the accuracy of the test results. After the test is completed, the results are displayed digitally on the display (17). After the test is completed, the right-angle rod (33) begins to move diagonally upward, thereby driving the connecting plate (22) to rise, and then driving the detector (12) to rise. At the same time, the connecting plate (22) can be wound up by the winding component (5) to avoid the lifting plate (21) from squeezing the connecting line (52) during the rise and causing accidental damage. When the right-angle rod (33) rises, the smoothing plate (38) can be reset by the cooperation of the reset component (4), thereby preparing for the next test. When it rises to the top, the smoothing plate (38) can be rotated by the cooperation of the folding component (6), thereby removing the fabric from the top of the test table (13). The singeing step involves a vehicle speed of 100-150 m / min, using natural gas as the heat source, and 8-11 units of natural gas. In the desizing step, amylase is used for desizing, with an amylase dosage of 2-5 g / L, a penetrant dosage of 3-5 g / L, a machine speed of 60-80 m / min, a heat preservation and stacking at 50-60℃ for 25-35 min, two water washings at 80-90℃, and three water washings at 50-60℃.
