[0042] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0043] Next, reference is made to Figure 1 A treatment process for enhancing the toughness of the loop of a hook-and-loop fabric according to an embodiment of the first aspect of the present invention will be described in detail.

[0044] Reference is made to Figure 1 , a treatment process for enhancing the toughness of the loop of a hook-and-loop fabric according to an embodiment of the first aspect of the present invention includes, but is not limited to, steps S100, S200, S300, S400, S500, and S600:

[0045] Step S100: Perform low-temperature heat setting treatment on the fabric with loops at 98 - 102 °C;

[0046] Step S200: Immerse the fabric in a refining solution for refining treatment;

[0047] Step S300: Immerse the fabric in a dye solution for dyeing treatment;

[0048] Step S400: Perform resin setting treatment on the loops of the fabric;

[0049] Step S500: Immerse the fabric in a mixed solution containing citric acid and a smoothing softener;

[0050] Step S600: Keep the fabric in a dry state.

[0051] In the processing technology of the present application, first, the fabric with loops is subjected to low-temperature heat setting treatment at a temperature of 98 - 102 °C to make the loops on the fabric in a fluffy state. Then, the fabric after heat setting treatment is immersed in a refining solution for refining treatment to remove impurities on the fabric. Then, the fabric is immersed in a dyeing solution for dyeing. Next, resin setting treatment is carried out on the loops of the fabric to make the shape of the loops of the fabric in a relatively stable state. Then, the fabric after resin setting is immersed in a mixed solution, where the mixed solution contains citric acid and a smoothing softener. Finally, the fabric is dried to keep the fabric in a dry state. It can be known from the above processing technology that by immersing the fabric after resin setting in a mixed solution containing citric acid and a smoothing softener, the toughness of the loops on the fabric can be further improved, the loops on the hook-and-loop fabric are not easily broken, and thus the service life of the loops of the hook-and-loop fabric is improved.

[0052] It can be understood that fabrics dyed with different colors need to be immersed in different mixed solutions to reduce the possibility of color mixing between fabrics of different colors.

[0053] It can be understood that by subjecting the loops on the fabric to low-temperature heat setting treatment to make the loops in a fluffy state, it is beneficial for the loops of the fabric to be refined and dyed. And when the loops are in a fluffy state, the abrasion area of the loops of the fabric is increased, further enhancing the adhesiveness of the fabric.

[0054] It can be understood that in some other embodiments of the present invention, there is no need to perform dyeing treatment on the fabric.

[0055] Specifically, the material of the loops on the fabric is nylon, and the smoothing softener is the smoothing softener with the model number TS-681C produced by Guangdong Taiyi High-Tech Materials Technology Co., Ltd.

[0056] In some embodiments of the present invention, step S500 includes but is not limited to the following steps:

[0057] Immerse the fabric in a mixed solution at a temperature of 68 - 72 °C and soak for 62 - 68 min.

[0058] It can be understood that by soaking the fabric with loops in a mixed solution at a temperature of 68 - 72°C and mixed with citric acid and a smoothing softener for 62 - 68 minutes, the citric acid and the smoothing softener can fully react with the loop fibers on the fabric, improving the softness of the fabric loops, reducing the possibility of pilling of the fabric loops, enhancing the toughness of the loops on the fabric, and since the mixed solution of citric acid and the smoothing softener improves the hydrophilic property of the loop fibers, when the fabric is in a relatively dry environment, the loops on the fabric are not easily broken.

[0059] It can be understood that since citric acid is an acidic substance that is not easily volatile, citric acid can be stored in the loop fibers of the fabric for a long time.

[0060] In one embodiment of the present invention, in the mixed solution, the content of citric acid is 0.95 - 1.05 g / L, and the content of the smoothing softener is 4.5 - 4.7 g / L.

[0061] Specifically, when the content of citric acid in the mixed solution is 1 g / L and the content of the smoothing softener is 4.6 g / L, soaking the fabric in this mixed solution can achieve the best effect of enhancing the toughness of the loops on the fabric.

[0062] In some embodiments of the present invention, step S100 includes but is not limited to the following steps:

[0063] Step S110: Place the fabric in a shaping cylinder;

[0064] Step S120: Evacuate the shaping cylinder with the fabric placed inside;

[0065] Step S130: Raise the temperature inside the shaping cylinder to 98 - 102°C and maintain it for 55 - 65 minutes;

[0066] Step S140: After the fabric cools down, take out the fabric.

[0067] It can be understood that in order to perform low-temperature heat setting on the fabric, the fabric needs to be first placed in a shaping cylinder, and then the shaping cylinder with the fabric is evacuated to make the loops on the fabric in a fluffy state. At this time, by raising the temperature inside the shaping cylinder to 98 - 102°C and maintaining the vacuum state for 55 - 65 minutes, during this period, the fabric will undergo slight deformation due to being in an environment with a temperature of 98 - 102°C, thereby achieving heat shaping of the loops on the fabric. When the fabric cools down, the loops on the fabric can remain in a fluffy state, and then the fabric is taken out.

[0068] In a specific embodiment of the present invention, step S140 includes the following steps:

[0069] Step S141: Depressurize the setting cylinder so that the air pressure inside the setting cylinder is the same as the external air pressure;

[0070] Step S142: Open the setting cylinder;

[0071] Step S143: After the fabric is naturally cooled for 10 min, take out the fabric from the setting cylinder.

[0072] In some embodiments of the present invention, step S200 includes but is not limited to the following steps:

[0073] Immerse the fabric in a scouring solution with a temperature of 77 - 83 °C and a pH value of 10 - 12, and soak for 27 - 33 min continuously.

[0074] It can be understood that when the fabric needs to be immersed in the scouring solution for scouring treatment, by soaking the fabric in a scouring solution with a temperature of 77 - 83 °C, and the pH value of the scouring solution is 10 - 12, and the fabric is soaked in the scouring solution for 27 - 33 min, so that the scouring solution reacts fully with the fabric, thereby removing impurities such as oil in the fabric, and by soaking the fabric in a scouring solution with a pH value of 10 - 12, the internal stress of the loops on the fabric is reduced, thereby reducing the brittleness of the loops, and further improving the toughness of the loops.

[0075] Specifically, the scouring solution is an aqueous sodium hydroxide solution.

[0076] In some embodiments of the present invention, step S300 includes but is not limited to the following steps:

[0077] Step S310: Immerse the fabric in a dyeing solution with a temperature of 96 - 100 °C, and soak for 180 - 200 min continuously;

[0078] Step S320: Soften the dyed fabric.

[0079] It can be understood that by soaking the fabric in a dyeing solution with a temperature of 96 - 100 °C, and soaking the fabric in the dyeing solution for 180 - 200 min, so that the dyes in the dyeing solution can fully penetrate into the fabric. Since the temperature of the dyeing solution is 96 - 100 °C, the dyes in the dyeing solution can penetrate into the fabric more quickly. At the same time, since the temperature of the dyeing solution is lower than 100 °C, the risk of embrittlement of the loops on the fabric is reduced.

[0080] In some of the embodiments of the present invention, step S320 includes but is not limited to the following steps:

[0081] Immerse the dyed fabric in an ice acetic acid solution with a temperature of 65 - 75 °C and a mass concentration of 0.45 - 0.55 g / L, and soak for 27 - 33 min continuously.

[0082] It is understandable that by immersing the dyed fabric in an acetic acid solution at a temperature of 65 - 75°C and with an acetic acid content of 0.45 - 0.55 g / L, and allowing the fabric to soak in the acetic acid solution for 27 - 33 min, the loops on the fabric react with the acetic acid during the soaking process, further improving the softness of the loops on the fabric.

[0083] In some embodiments of the present invention, step S400 includes but is not limited to the following steps:

[0084] Step S410: Apply resin to the loops of the fabric;

[0085] Step S420: Allow the resin on the fabric to come into full contact with air;

[0086] Step S430: Place the fabric in an environment at 47 - 53°C and leave it for 230 - 250 min.

[0087] It is understandable that after the fabric is immersed in the mixed solution for a period of time, first apply resin to the loops of the fabric, then evenly loosen the loops coated with resin to allow the resin to come into full contact with air, and then place the fabric in an environment at 47 - 53°C and keep it for 230 - 250 min, so that the resin can fully and evenly adhere to the loops, improving the wear resistance and toughness of the loops of the hook - and - loop fabric, thereby extending the service life of the hook - and - loop fabric.

[0088] Specifically, when the resin on the fabric is fully in contact with air, place the fabric in an oven at 47 - 53°C and leave it for 230 - 250 min to completely cure the resin and form a protective film on the loops of the webbing.

[0089] In some embodiments of the present invention, step S600 includes but is not limited to the following steps:

[0090] Put the fabric into an oven, keep the temperature of the oven at 77 - 83°C, and leave it for 230 - 250 min.

[0091] It is understandable that by placing the fabric soaked in the mixed solution in an oven at 77 - 83°C and keeping it for 230 - 250 min, the fabric can quickly reach a dry state.

[0092] It is understandable that after the fabric is taken out of the mixed solution and before being put into the oven, it is necessary to filter the water from the fabric to reduce the moisture content of the fabric, facilitating its placement in the oven.

[0093] The following provides a detailed description of a die - cutting production line according to an embodiment of the second aspect of the present invention.
