Description

TECHNICAL FIELD

[0001] The present application relates to a loom warp on-machine instant color detection device and detection method. BACKGROUND

[0002] Currently, the raw materials used in weaving are various, including various natural fibers and chemical fibers, etc. On the warp, two or more different raw materials with different properties are often combined together according to a certain arrangement to play the combined performance of various raw materials on the cloth surface. Since the loom weaves gray cloth without dyeing processing, these different raw materials are basically white, and the arrangement method cannot be distinguished after complex arrangement during weaving; these arrangement errors may be production process errors, warping arrangement errors, harnessing errors, and head mounting errors, etc., and these errors cause the arrangement of multiple raw materials on the cloth surface to be wrong, especially when the arrangement of raw materials corresponds to the structure of the cloth surface, the style error of the cloth surface is more obvious, which does not meet the product requirements. The processing method of the weaving mill for the above-mentioned possible errors is to pause weaving after normal starting, cut a section of full-width gray cloth about 50 cm, add corresponding dyes in an electric rice cooker for boiling, cleaning and washing, and then observe the arrangement of the warp on the cloth surface, and then notify the loom to normal production, resulting in low production efficiency. SUMMARY

[0003] The purpose of the present application is to provide a loom warp on-machine instant color detection device that can quickly obtain detection results.

[0004] To solve the above technical problems, the present application adopts the following technical scheme: a loom warp on-machine instant color detection device, which comprises a shell, a temperature control detector and a heater arranged in the shell, a water outlet valve arranged at the bottom of the shell, and a button for controlling the opening and closing of the water outlet valve, wherein the water outlet valve has a plurality of water outlet holes with an inner diameter of less than 2 mm.

[0005] In another embodiment, the water outlet holes are uniformly distributed, and the distance between adjacent two water outlet holes is not less than 2 mm.

[0006] In another embodiment, the bottom of the shell is made of rubber.

[0007] In another embodiment, the shell has a handle for easy gripping, and the button is installed on the handle.

[0008] In another embodiment, the shell has a water injection hole for injecting water into the shell.

[0009] The present application also provides a detection method based on the above-mentioned loom warp on-machine instant color detection device, which comprises the following steps:

[0010] a. Fill the shell with water, add cationic dye, shake gently to mix evenly, adjust the temperature to above 85°C, and then turn on the power to heat. When the temperature reaches the set point, shake the shell to disperse the dye evenly.

[0011] b. Place the casing on the fabric surface, place a pad on the fabric roll, align the fabric surface with the pad, and move it along the axial direction of the fabric roll from one end to the other. At the same time, press the button to allow the dye to penetrate the fabric surface through the water outlet of the water valve. When the dye comes into contact with the cationic raw material on the fabric surface, the cationic raw material begins to dye, while the conventional polyester yarn does not dye. When the casing reaches the far right, ensure that all warp surfaces are soaked in the dye. Remove the casing, wet the fabric surface with absorbent material, and wipe the fabric surface along the axial direction of the fabric roll from one end to the other. Wipe away any dye adhering to the surface of the conventional polyester yarn on the warp threads. At this point, you can see that all warp yarns have two colors: the color of the cationic raw material and the color of the conventional polyester yarn.

[0012] c. Then search according to the arrangement order specified in the process, check and confirm whether the position is correct, and correct any errors immediately;

[0013] d. Finally, remove the rubber pads from the fabric support, and the machine can be started for normal production.

[0014] The beneficial effects of this invention are: it is very convenient and quick to distinguish different warp yarns of various fabrics after dyeing, with no safety hazards or side effects, and realizes online real-time inspection of fabrics. Attached Figure Description

[0015] Appendix Figure 1 This is a schematic diagram of the detector structure of the present invention;

[0016] Appendix Figure 2 This is a schematic diagram of the detector in use. Detailed Implementation

[0017] like Figure 1 As shown, a fabric loom warp yarn instantaneous dye absorption detector includes a housing, a temperature control detector and heater disposed within the housing, a water outlet valve located at the bottom of the housing, and a button for controlling the opening and closing of the water outlet valve. The water outlet valve has multiple water outlet holes with an inner diameter of less than 2 mm. The water outlet holes are evenly distributed, and the distance between two adjacent water outlet holes is not less than 2 mm. The bottom of the housing is made of rubber. The housing has a handle for easy gripping, and the button is mounted on the handle. The housing also has a water injection hole for injecting water into the housing.

[0018] Research on textile raw materials with different properties has revealed that the dyes and dyeing temperatures used for dyeing commonly used textile raw materials each have their own characteristics, as shown in Table 1:

[0019]

[0020]

[0021] Table 1 Simplified dyeing performance of common textile raw materials

[0022] As can be seen from the table, different dyes are used for dyeing different textile raw materials, and the dyeing temperature also differs; some raw materials have multiple dyes, some of which are the same and some of which are different, making it convenient to choose. For the most commonly used water-jet looms at present, since the warp yarns of all raw materials are filament yarns, such as conventional polyester, cationic polyester, and nylon, different dyes can be selected for dyeing, that is, before dyeing, the raw materials are all white (except for color-woven cloth), and after dyeing, one kind of raw material is colored (selecting the color of the appropriate dye), and the other kind of raw material is not colored, which facilitates the differentiation of raw materials by dyeing. For the differentiation of short fiber raw materials used in air-jet or rapier looms, the above method can be adjusted accordingly.

[0023] When conventional polyester yarns are used as warp yarns for weaving on a water-jet loom, and cationic polyester yarns are used as warp yarns for weaving in various arrangements, the positions of different warp yarns on the loom are distinguished to verify whether the arrangement method and the corresponding healding method meet the requirements of the process design, and the arrangement is corrected in a timely manner if there is an error. In view of the dyeing properties of the two kinds of warp yarns, cationic dyes are used for online detection. This dye immediately colors the cationic raw material, while the conventional polyester raw material does not absorb color. According to the color absorption or non-absorption, it is determined whether the positions of the warp yarns and the corresponding weave structure of the warp yarn arrangement on the fabric surface meet the requirements of the process design, and the position is corrected immediately if there is an error.

[0024] The method for detecting the immediate color absorption of warp yarns on a loom comprises the following steps:

[0025] a. Add water and cationic dye to the shell, shake gently to mix evenly, adjust the temperature to above 85°, then power on and heat, and when the heating is in place, shake the shell to disperse the dye evenly;

[0026] b. Then place the shell on the fabric surface, pad a layer of gasket (the gasket can be a rubber pad) on the fabric surface, align the fabric surface on the gasket, and move along the axial direction of the fabric roll from one end to the other while pressing the button, so that the dye solution penetrates through the water outlet hole of the water outlet valve to the fabric surface. When the dye solution comes into contact with the cationic raw material on the fabric surface, the cationic raw material begins to dye, while the conventional polyester yarn does not dye. When the shell reaches the far right, ensure that all warp positions are infiltrated with dye solution, remove the shell, and then wipe the fabric surface from one end to the other along the axial direction of the fabric roll with a water-absorbing material soaked with water to wipe off the little dye that the conventional polyester yarn on the warp of the fabric surface has absorbed on its surface. At this time, it can be seen that all the warp yarns have two colors, namely the color of the cationic raw material and the color of the conventional polyester;

[0027] c. According to the arrangement order of the process, check if the position is correct, and change it immediately if there is any error;

[0028] d. Remove the rubber pad on the cloth support, and then the machine can be normally started.

[0029] For different textile materials, the dyes used for most materials are different, such as disperse dyes for conventional polyester, cationic dyes for cationic polyester, reactive dyes for cotton yarn, acid dyes for nylon, and so on. Except for disperse dyes, the other dyes are normal temperature dyes. According to the above principle and the detector shown in the above, the online detection method using cationic dyes for the dyeing properties of the two example warp materials is as follows. Figure 2

[0030] a. After the cloth machine is normally started, the rubber pad 9 in the figure is laid flat on the cloth roller 8, the cloth surface 10 is placed below, and the shell is filled with about 400 ml of water, about 1 g of cationic dye (temporary selection of sky blue) is added, and the temperature is adjusted to 90 degrees. Then, the handle of the dyeing shell is taken, and the dye is evenly dispersed by gently shaking;

[0031] b. Then, the shell is placed on the cloth surface 10, aligned with the middle of the rubber pad 9, and slowly moved from left to right, while pressing the handle button 5, so that the dyeing liquid penetrates to the cloth surface through the micropores of the rubber. When the dyeing liquid contacts the cationic material on the cloth surface 10, the cationic material starts to dye, while the conventional polyester yarn does not dye. When the shell reaches the right side, ensure that all warp positions are contacted (if necessary, it can be walked again), and the dyeing shell is removed, and the cloth surface 10 is gently wiped from left to right with a water-soaked sponge to wipe off the little dye on the surface of the conventional polyester yarn on the cloth surface. At this time, it can be seen that all warp yarns have two colors, i.e. sky blue of the cationic material and white of the conventional polyester;

[0032] c. According to the arrangement order of the process, check if the position is correct, and change it immediately if there is any error;

[0033] d. Remove the rubber pad 9 on the cloth support, and then the machine can be normally started.

[0034] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.​
