Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silk fabric processing, and particularly relates to a weft yarn tension interval compensation fabric flatness treatment method suitable for silk fabric, a flatness device and control electronic equipment thereof. BACKGROUND

[0002] In the field of silk fabric production and processing, fabric flatness is one of the core indicators determining product quality, and uneven weft yarn tension is a key factor leading to problems such as wrinkles, skew, and uneven tightness on the surface of silk fabric. Silk fabric uses silk as raw material, and the fiber naturally has the characteristics of being fine, low in elasticity, and easily deformed in a wet state. In the weaving, dyeing and finishing, and post-processing links, the weft yarn (fabric horizontal yarn) is prone to tension fluctuations due to various factors: in the weaving stage, unstable weft feeding speed of the loom, slight differences in weft thickness, and uneven clamping force of the warp yarn on the weft yarn, will cause some weft yarns to be excessively stretched or in a relaxed state; in the dyeing and finishing stage, silk needs to go through high-temperature washing and dyeing processes, and the shrinkage rates of weft yarns in different areas are different due to the influence of temperature and humidity, and the weft yarns with high tension shrink more significantly, further exacerbating the unevenness of the fabric surface; in the post-processing stage, processes such as printing and gold stamping exert tension on the fabric locally, which easily causes local deformation of the weft yarn, forming defects such as "bumps" and "wrinkle marks". These problems not only seriously affect the appearance and luster of silk fabric (uneven tension will cause differences in light reflection, resulting in "yin and yang surfaces"), but also cause the fabric pattern to be distorted when cutting and making clothes, reducing the added value of the product. Therefore, there is an urgent need for a treatment technology that can accurately adjust the weft yarn tension and ensure the flatness of the fabric surface to solve the core quality problems in silk fabric production.

[0003] Traditional silk fabric fabric flatness treatment technologies mostly follow the overall tension adjustment scheme for conventional fabrics such as cotton and chemical fibers, and the core idea is to apply overall stretching force to the fabric through multiple rotating roller groups, and to increase the longitudinal (warp direction) tension of the fabric with the help of auxiliary pressing plates, thereby achieving fabric flatness. For example, some enterprises use multi-roller linkage stretching and setting equipment to longitudinally pull the fabric by adjusting the speed difference of the roller bodies, trying to cover up the local weft yarn tension problem through overall tension balance; there are also technologies that use high-temperature calendering machines to roll and press the surface of the fabric, temporarily smoothing out wrinkles. The advantages of such traditional schemes are relatively simple structure and low operation threshold, and they can achieve certain effects when processing stable structure cotton fabrics or chemical fiber fabrics with high fiber strength, but they have significant defects when applied to silk fabrics: on the one hand, overall stretching easily causes the fine silk fibers to break, producing "fluff", and damaging the delicate texture and luster of the fabric; on the other hand, traditional technologies can only adjust the warp direction tension, and have weak improvement effect on the uneven weft yarn tension, and cannot fundamentally solve the horizontal fabric unevenness caused by weft yarn tension differences, and even exacerbate the weft yarn tension imbalance due to excessive stretching, forming new quality problems, making it difficult to meet the stringent requirements of high-end silk fabrics on fabric flatness.

[0004] With the improvement of the quality requirements of silk fabrics in the industry, the existing technology begins to try to optimize the weft tension adjustment, but there are still obvious limitations. Some existing technologies set a transversely movable tension detection roller on the finishing machine to sample the weft tension at a single point, and then manually adjust the roller pressure to achieve local compensation. Although this method can adjust the weft tension specifically, it relies on manual operation, has low detection accuracy (single-point sampling cannot cover the tension distribution across the width), and the compensation parameters are set entirely by experience, making it difficult to adapt to the tension adjustment needs of different widths and different varieties of silk fabrics, with low automation and limited production efficiency. Another technology combines wet heat setting and tension adjustment, which applies a low-temperature and humid heat environment to the entire fabric, and uses the plasticity of silk to improve tension unevenness. However, this technology does not distinguish abnormal tension areas, and overall wet heat treatment can cause excessive shrinkage or stretching in normal tension areas, which can damage the flatness of the fabric surface, and cannot accurately solve the problem of local weft tension abnormalities. The application scenarios have great limitations, and a mature and efficient silk fabric weft tension accurate adjustment technology system has not been formed.

[0005] Chinese patent (CN104261178A) discloses a window cloth wrinkle removal and weft adjustment winding stabilizing device. The device sets a weft adjustment cylinder between the unwinding cylinder and the winding cylinder, and uses the relative horizontal sliding of the central fixed part and the sliding side part of the adjustment surface to apply a horizontal traction force to the window cloth to achieve wrinkle removal and weft tension adjustment. This technology targets the characteristics of window cloth (mostly chemical fiber or cotton blended materials with high fiber strength and large thickness), improves weft tension through mechanical structure sliding traction, and has certain applicability in window cloth processing field, but has serious shortcomings. The adjustment surface of the device achieves traction force application through the "close-far" of the sliding side part and the central fixed part, and the traction force cannot be accurately controlled. The device uniformly tractions the entire fabric surface without identifying and compensating abnormal tension areas. For silk fabrics with slight tension differences, it can easily cause local over-traction or insufficient traction, and even damage the silk fibers. Secondly, the device does not have a tension detection and feedback mechanism, cannot obtain weft tension data in real time, and relies entirely on the inherent motion trajectory of the mechanical structure for adjustment, with extremely low adjustment accuracy, making it difficult to adapt to the fine requirements of silk fabric tension adjustment.

[0085] Based on the embodiment 1 or 2, the embodiment describes the electronic control device suitable for the application in detail, which comprises a memory, a processor, a transmitter and a receiver, as shown in Figure 3 The specific embodiments are as follows:

[0086] The memory is used for storing the standard tension parameter and the different tension compensation parameter calculation logic;

[0087] The processor calls the parameter data in the memory to obtain the tension compensation parameter of the abnormal detection area through the different tension compensation parameter calculation logic;

[0088] The transmitter is used for converting the tension compensation parameter generated by the processor into a control instruction and sending, so as to realize the weft tension interval compensation cloth surface flatness treatment method suitable for silk fabric in any one of claims 1 to 8;

For the discrete abnormal areas, the compensation parameters are generated by the formula. After the calculation of the parameters is completed, the processor transmits the results to the transmitter. The transmitter accurately sends the control instructions to each independent adjustment unit of the interval tension adjustment unit according to the corresponding relationship between the detection unit and the adjustment unit, and controls the tensioning roller or the decompression roller to perform the stretching and relaxing operation.

[0095] The pressure feedback unit of the interval tension adjustment unit acquires the actual pressure value in real time, returns the value to the processor through the receiver, and compares the actual pressure value with the target pressure value. If the deviation exceeds the preset threshold, the processor immediately recalculates the adjusted compensation parameters, issues adjustment instructions through the transmitter, and realizes the closed-loop control of "parameter storage-data processing-instruction sending-feedback adjustment", thereby ensuring the accuracy and stability of the entire weft tension interval compensation process and adapting the operation requirements of the processing method and device.

[0096] The embodiment describes in detail that the electronic control device realizes the closed-loop control of storage-computation-instruction-feedback, which not only improves the weft tension compensation accuracy and the flatness of the silk fabric, but also reduces the manual error, improves the processing efficiency, and adapts to different types.

[0097] Embodiment 3

[0098] This embodiment describes in detail that the present application obtains specific technical effects by comparing the tension interval compensation processing of the warp and weft of real silk satin and georgette, which are specifically:

[0099] Select 22.5-mil real silk satin (width 1.58 m, fiber diameter about 12.8 μm) and 14.2-mil georgette (width 1.43 m, fiber diameter about 8.5 μm) commonly used in the textile industry as experimental samples, complete 3 sets of parallel experiments in a standard experimental environment of constant temperature 25.3℃ and relative humidity 60.5%, and all test data are average values measured by professional instruments after the experiment to objectively verify the processing effect of the present application on different varieties of silk fabrics.

[0100] Before the experiment, the standard tension parameters of the two types of fabrics are preset in the memory of the electronic control equipment: the standard tension range of real silk satin is set to 0.32-0.48 N because the fiber is relatively thick and the tension tolerance is slightly high; the standard tension range of georgette is set to 0.16-0.24 N because the fiber is thin and easy to be damaged by stretching. During the processing, the device automatically adjusts the core parameters according to the characteristics of the two types of fabrics, and finally completes the detection of key indicators through the laser flatness detector, fiber microscope, gloss meter and timer;

[0101] Figure 4 The comparison chart of the fabric flatness error of the two types of fabrics before and after processing (detection accuracy 0.01 mm / m, horizontal detection interval consistent with the detection unit interval of the device, and 1 detection point every 12 cm in the vertical direction). Before processing, the maximum value of the flatness error of real silk satin is 0.423 mm / m, the minimum value is only 0.085 mm / m, and the difference is 0.338 mm / m due to uneven weft tension; the maximum value of the flatness error of georgette is 0.352 mm / m, the minimum value is 0.072 mm / m, and the difference is 0.280 mm / m. After processing by the present application, the maximum value of the flatness error of real silk satin is reduced to 0.112 mm / m, the minimum value is 0.068 mm / m, and the difference is only 0.044 mm / m; the maximum value of the flatness error of georgette is 0.081 mm / m, the minimum value is 0.059 mm / m, and the difference is 0.022 mm / m. From Figure 1 It can be clearly observed that the flatness error curve of the two types of fabrics after processing tends to be flat without local protrusions or depressions, which proves that the present application can effectively eliminate the unevenness of the fabric surface of different varieties of silk fabrics caused by uneven weft tension, and the improvement effect of the flatness of georgette with lower tension tolerance is more significant.

[0102] Using a fiber microscope with magnification ranging from 1 to 400x, ten 2mm × 2mm detection areas were randomly selected from each type of fabric, and the percentage of broken fibers was statistically analyzed. Experimental data showed that the fiber damage rate of silk satin after treatment was only 0.52%, and that of georgette was 0.31%, both significantly lower than that of traditional overall stretching treatment technology (the industry average fiber damage rate is 3.2%-5.1%). Figure 5 The microscope image shows (left side) Figure 5 (a) is the finished product of silk satin; right side Figure 5 (b) shows the georgette after treatment. In both types of fabrics, the silk fibers maintained their complete filament shape, without any "fuzz" or fiber breakage. The microfibers of the georgette showed no stretching deformation, and the coarse fibers of the silk satin did not suffer structural damage due to excessive pressure. This result demonstrates that this application can precisely control the compensation force according to the characteristics of different types of silk fibers, solving the tension problem while maximizing the protection of the fiber's natural structure and ensuring the fabric's delicate texture.

[0103] Figure 6 A comparison of the gloss uniformity of the two types of fabrics before and after processing was shown (measured using a 60° angle gloss meter, with 20 test points selected for each type of fabric, and a test accuracy of 0.1 GU). Without treatment, the maximum gloss of the silk satin was 52.3 GU, the minimum was 38.1 GU, and the difference was 14.2 GU, with obvious "yin-yang" patterns appearing on the fabric surface due to uneven tension; the maximum gloss of the georgette was 45.2 GU, the minimum was 32.3 GU, and the difference was 12.9 GU, with some areas showing dullness due to weft yarn relaxation. After the treatment described in this application, the maximum gloss of the silk satin was 51.8 GU, the minimum was 47.2 GU, and the difference was only 4.6 GU; the maximum gloss of the georgette was 44.3 GU, the minimum was 40.1 GU, and the difference was 4.2 GU. Figure 6 The fluctuation range of the gloss curve after the treatment was significantly reduced, and the light reflection on the surface of the two types of fabrics was uniform. This proves that the present application can effectively improve the gloss distribution of different types of silk fabrics through precise weft tension compensation, avoid uneven gloss caused by tension differences, and has a better effect on improving gloss uniformity for georgette, which is more sensitive to gloss.

[0104] Meanwhile, the average processing time per batch for silk satin was 58.2 min, with the three experimental groups yielding times of 58.1 min, 58.3 min, and 58.2 min respectively, a deviation of only ±0.1 min; the average processing time per batch for georgette was 55.3 min, with the three experimental groups yielding times of 55.2 min, 55.4 min, and 55.3 min respectively, a deviation of ±0.1 min. Compared to the traditional manual tension adjustment method (average processing time per batch 92-118 min, time deviation ±8 min), this application demonstrates a significant improvement in processing efficiency and extremely high stability.

[0105] The embodiment is described in detail. Without complex equipment modification for different varieties of silk fabrics, only by presetting parameters of the electronic control equipment, accurate processing of real silk satin and georgette yarn can be realized, excellent effects are exhibited on fabric flatness, fiber protection, uniform gloss and processing efficiency, and the wide adaptability and high processing capacity of the application to different varieties of silk fabrics are fully proved.

[0106] The above are only preferred embodiments of the present application, and not to limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and variations; any change, modification, replacement, integration and parameter change of these embodiments within the spirit and principles of the present application, which can realize the same function without departing from the principles and spirit of the present application, all fall within the protection scope of the present application.
