Description

Technical Field

[0001] The present invention relates to a production process, in particular to a production process of a far and near infrared-proof polyester fabric applied to the technical field of fabric production. Background Art

[0002] In modern industry and daily life, polyester fabrics are widely used in many fields such as clothing, home, military, and aerospace due to their excellent physical and chemical properties, such as high strength, high abrasion resistance, good dimensional stability, and wrinkle resistance. However, with the development of technology and the expansion of application scenarios, in special scenarios such as military camouflage, infrared detection protection, medical equipment protection, and high-temperature operation protection, new requirements are put forward for the infrared protection performance of polyester fabrics. Far and near infrared radiation is easy to penetrate ordinary polyester fabrics, resulting in the exposure of information of relevant equipment and personnel, or causing adverse effects on the human body due to the infrared radiation heat effect. Ordinary polyester fabrics can no longer meet the requirements for the function of preventing far and near infrared in these fields.

[0003] In the prior art, although there are some fabrics with infrared protection functions. For example, Chinese Patent with Publication No. CN102628226B discloses a printing process for a far infrared detection-proof camouflage fabric. This invention uses a unique printing process to obtain a camouflage fabric that can prevent detection by far infrared detection instruments; Chinese Patent with Publication No. CN106364106B discloses a special fabric for anti-reconnaissance equipment. The special fabric for anti-reconnaissance equipment in this invention has the anti-reconnaissance function of preventing near infrared. However, these prior arts generally have the problem of single functionality, and can only achieve the protection of one of the far infrared or near infrared bands, and cannot meet the requirements for simultaneous protection of far and near infrared bands in practical applications. Therefore, we propose a production process of a far and near infrared-proof polyester fabric. Summary of the Invention

[0004] Aiming at the above prior art, the technical problem to be solved by the present invention is: how to produce a polyester fabric that can prevent both far infrared and near infrared.

[0005] To solve the above problems, the present invention provides a production process of a far and near infrared-proof polyester fabric, including the following steps:

[0006] S1. Prepare a far infrared-proof polyester base fabric:

[0007] S11. Uniformly disperse a far infrared-proof additive in molten polyester at a mass ratio of 0.01%-10% to form a spinning solution. The far infrared-proof additive is one or more of oxides or simple substances of nickel, zirconium, titanium, zinc, silver, aluminum, silicon, copper, carbon, and nitrogen, and the particle size is 5nm - 5μm;

[0008] S12. Spinning is carried out using a spinning solution, controlling the fineness of the single fiber to be 0.3 - 1.5 denier to obtain far-infrared-proof polyester filaments;

[0009] S13. The far-infrared-proof polyester filaments are woven by an air-jet loom to obtain a far-infrared-proof polyester base fabric;

[0010] S14. The far-infrared-proof polyester base fabric is treated with low temperature and low alkali, treated in a sodium carbonate solution of 0.4 - 2 g / L at 80 °C for 10 - 30 minutes, and washed with water for later use;

[0011] S2. Near-infrared-proof dyeing:

[0012] S21. Select disperse dyes with a reflectance of 10% - 70% in the wavelength range of 700 nm - 1300 nm. The disperse dyes include red, yellow, blue, navy blue, black, golden yellow, and turquoise blue;

[0013] S22. Mix two or more disperse dyes in a set ratio, add an environmentally friendly carrier, and dye the far-infrared-proof polyester base fabric treated in step S14 at 115 °C - 130 °C. Regulate the dyeing process so that the final color parameters meet the L, a, b, C, and H of the target chromaticity value, and the deviation of the reflectance curve in the wavelength range of 700 nm - 1300 nm from the environmental target value ≤ 5%. After dyeing, the far-near-infrared-proof polyester fabric can be obtained.

[0014] In the production process of the above far-near-infrared-proof polyester fabric, the produced polyester fabric has both far-infrared-proof function and near-infrared-proof function.

[0015] As a further improvement of the present application, in step S11, the dispersion of the far-infrared-proof additive is carried out by high-speed shear stirring or ultrasonic dispersion.

[0016] As a further improvement of the present application, when weaving in step S13, a warp and weft yarn combination of 50D / 72F FDY × 50D / 72F FDY is used, the weaving density is 185 × 107, and the gram weight is 60 - 70 g / m 2 .

[0017] As a further improvement of the present application, the environmentally friendly carrier in step S22 is one of dibutyl phthalate, biphenyl, or decamethylcyclopentasiloxane.

[0026] S35. Preset a water-washing friction duration. After the time of dry simulation friction treatment reaches the dry friction duration, start the lifting cylinder to drive the simulation friction assembly to move downward until the specimen is immersed in the water-washing water to perform water-washing simulation friction treatment on the specimen.

[0027] S36. After the time of water-washing simulation friction treatment reaches the water-washing friction duration, turn off the friction push-pull cylinder, control the lifting cylinder to drive the simulation friction assembly to move upward and reset, and then remove the specimen.

Specific implementation manner

[0045] The following will make a detailed description of the three implementation manners of this application with reference to the accompanying drawings.

[0046] The first implementation manner:

[0047] Figure 1 A production process of anti-near and far infrared polyester fabric is shown, including the following steps:

[0048] S1. Prepare the anti-far infrared polyester base fabric:

[0049] S11. Uniformly disperse the anti-far infrared additive in the molten polyester according to a mass ratio of 0.01%-10% to form a spinning solution. The anti-far infrared additive is one or more of oxides or simple substances of nickel, zirconium, titanium, zinc, silver, aluminum, silicon, copper, carbon, and nitrogen, and the particle size is 5nm-5μm;

[0050] S12. Spinning is carried out using a spinning solution, controlling the fineness of the single fiber to be 0.3 - 1.5 denier to obtain far-infrared-proof polyester filaments;

[0051] S13. The far-infrared-proof polyester filaments are woven by an air-jet loom to obtain a far-infrared-proof polyester base fabric;

[0052] S14. The far-infrared-proof polyester base fabric is subjected to low-temperature and low-alkali treatment, treated in a sodium carbonate solution of 0.4 - 2 g / L at 80 °C for 10 - 30 minutes, and washed with water for later use;

[0053] S2. Near-infrared-proof dyeing:

[0054] S21. Disperse dyes with a reflectance of 10% - 70% in the wavelength range of 700 nm - 1300 nm are screened. The disperse dyes include red, yellow, blue, navy blue, black, golden yellow, and turquoise blue;

[0055] S22. Two or more disperse dyes are mixed in a set ratio, an environmentally friendly carrier is added, and the far-infrared-proof polyester base fabric treated in step S14 is dyed at 115 °C - 130 °C. The dyeing process is regulated so that the final color parameters meet the L, a, b, C, and H of the target chromaticity value, and the deviation of the reflectance curve in the wavelength range of 700 nm - 1300 nm from the environmental target value is ≤ 5%. After dyeing is completed, the far-near-infrared-proof polyester fabric can be obtained.

[0056] In step S11, the far-infrared-proof additive is dispersed by high-speed shear stirring or ultrasonic dispersion.

[0057] When weaving in step S13, a warp and weft yarn combination of 50D / 72F FDY × 50D / 72F FDY is used, the weaving density is 185 × 107, and the gram weight is 60 - 70 g / m 2 .

[0058] The environmentally friendly carrier in step S22 is one of dibutyl phthalate, biphenyl, or decamethylcyclopentasiloxane.

[0059] This application realizes the synchronous protection of the far-infrared and near-infrared bands through the co-blending spinning of far-infrared-proof additives and the dyeing process with precise regulation of the reflectance in the near-infrared band, solving the limitation of the prior art that can only protect a single band.

[0060] The second embodiment:

[0061] Figures 2 - 4 A production process of far-near-infrared-proof polyester fabric is shown. Different from the first embodiment, the production process further includes the following steps:

[0062] S3: Durability Test: Conduct a durability test on the far-near infrared-proof polyester fabric through a durability test system;

[0063] The durability test system includes a Fourier transform infrared spectrometer and a pseudo-friction treatment mechanism. The pseudo-friction treatment mechanism includes a water-washing simulation pool 101. The top of the water-washing simulation pool 101 is open, and the water-washing simulation pool 101 is filled with water-washing water (the water-washing water is tap water. To improve the authenticity of the simulation, an appropriate amount of detergent such as laundry detergent or washing powder can be added to the water-washing water). A lifting cylinder 102 is fixedly installed on the outer wall of the water-washing simulation pool 101. The output end of the lifting cylinder 102 is fixedly connected to a lifting connecting plate 103. A simulation friction assembly is arranged above the water-washing simulation pool 101. The simulation friction assembly includes a support seat 201 fixedly connected to the lifting connecting plate 103. The support seat 201 is L-shaped. A friction push-pull cylinder 202 is fixedly installed on the support seat 201. The output end of the friction push-pull cylinder 202 is fixedly connected to a push-pull connecting plate 203. The bottom end of the push-pull connecting plate 203 is fixedly connected to a U-shaped connecting seat 204. The bottom end of the connecting seat 204 is fixedly connected to a pair of specimen clamps 205. A pair of support columns 206 fixedly installed on the support seat 201 are arranged between the pair of specimen clamps 205. A friction sleeve 207 matching the support column 206 is sleeved on the top end of the support column 206.

[0064] Due to its special optical properties, the far-near infrared-proof polyester fabric has important application values in the fields of military camouflage, tactical equipment, medical protection, etc., and can be used to prepare products such as camouflage combat uniforms, tactical backpacks, infrared shielding curtains, and medical heat preservation protectors. However, in the actual use process, such fabrics need to withstand frequent mechanical friction, and as non-disposable items, they need to undergo multiple water-washing and cleaning processes. The surface structure damage caused by the friction effect and the loss of functional components during the washing process may both lead to the attenuation and failure of the infrared-proof performance of the fabric. To ensure the reliability of this material in complex usage scenarios, it is necessary to conduct a systematic durability test.

[0065] For the convenience of description, we refer to the mechanical friction suffered by the far-near infrared-proof polyester fabric product during the actual use process as daily friction. When the polyester fabric product is washed, it will also be subjected to friction. However, the difference is that during washing, the product is subjected to friction while being immersed in water, while daily friction occurs under relatively dry conditions.

[0066] The durability test includes the following steps:

[0067] S31. Cut a long strip of fabric from the far-near infrared-proof polyester fabric as a specimen. The length of the specimen matches the distance between the two specimen clamps 205;

[0068] S32. Detect the far-infrared resistance performance and near-infrared resistance performance of the test piece by a Fourier transform infrared spectrometer, and record the corresponding data;

[0069] S33. Insert the test piece between two friction sleeves 207, and clamp both ends of the test piece by a test piece clamp 205;

[0070] S34. Preset a dry friction duration (the dry friction duration is set according to factors such as application scenarios and actual requirements), start the friction push-pull cylinder 202, and make the friction push-pull cylinder 202 drive the test piece to move back and forth, so that the friction sleeve 207 performs dry simulated friction treatment on the test piece when the test piece is dry (that is, perform friction treatment on the test piece in a way that simulates daily friction);

[0071] S35. Preset a water washing friction duration (the water washing friction duration is set according to factors such as application scenarios and actual requirements). After the time of the dry simulated friction treatment reaches the dry friction duration, start the lifting cylinder 102, and make the lifting cylinder 102 drive the simulated friction assembly to move downward until the test piece is immersed in the washing water to perform water washing simulated friction treatment on the test piece (that is, perform friction treatment on the test piece in a way that simulates water washing);

[0072] S36. After the time of the water washing simulated friction treatment reaches the water washing friction duration, turn off the friction push-pull cylinder 202, control the lifting cylinder 102 to drive the simulated friction assembly to move upward and reset, and then remove the test piece;

[0073] S37. Detect the far-infrared resistance performance and near-infrared resistance performance of the test piece again by a Fourier transform infrared spectrometer, and record the corresponding data;

[0074] S38. Calculate the attenuation rates of the far-infrared resistance performance and near-infrared resistance performance of the test piece according to the data recorded twice to evaluate the durability of the far and near-infrared resistant polyester fabric.

[0075] In this embodiment, the durability test system can synchronously simulate the dry friction and wetting water washing friction conditions, truly simulate the composite damage mechanism of polyester fabric products in actual use, so as to comprehensively evaluate the durability of polyester fabric products in actual use. By comparing the infrared resistance performance data before and after the test, the attenuation of material performance can be intuitively understood, providing strong support for further optimizing the production process and improving product quality.

[0076] An anti-rotation plug rod 208 is fixedly installed on the inner wall of the friction sleeve 207. The anti-rotation plug rod 208 is arranged in a cuboid shape, so that the friction sleeve 207 cannot rotate, thereby ensuring the friction effect. An anti-rotation slot 209 matching the anti-rotation plug rod 208 is opened at the top end of the support column 206. The anti-rotation plug rod 208 is movably inserted into the anti-rotation slot 209. The friction sleeve 207 is provided with a variety of specifications according to its thickness, so that it can be adaptively adjusted by replacing different specifications of the friction sleeve 207 according to the thickness of the far and near infrared polyester cloth. For polyester cloth with a thicker thickness, a friction sleeve 207 with a smaller thickness can be used, and for polyester cloth with a thinner thickness, a friction sleeve 207 with a larger thickness is used.

[0077] The third implementation method:

[0078] Please refer to Figures 5 - 8 , different from the second implementation method, the quasi-friction treatment mechanism further includes a drying and assisting cross component. The drying and assisting cross component includes a heating cylinder 301. A heater 308 is fixedly installed in the heating cylinder 301. An air pump 302 is fixedly installed on the outer wall of the heating cylinder 301. The air inlet of the air pump 302 is communicated with the inside of the heating cylinder 301. The air outlet of the air pump 302 is communicated with a guide pipe 303. The drying and assisting cross component further includes a diversion box 304 arranged inside the connecting seat 204. One end of the guide pipe 303 away from the air pump 302 is communicated with the diversion box 304. A plurality of air guide holes 305 are opened at the bottom end of the diversion box 304. An air inlet pipe 306 communicated therewith is arranged on the outer wall of the heating cylinder 301. A heater 308 is arranged on the air inlet pipe 306. The quasi-friction treatment mechanism further includes a test intelligent control unit. The test intelligent control unit includes a test setting module, a test control module, and a drying control module. The test setting module is signal-connected to the test control module. The test control module is signal-connected to the lifting cylinder 102, the friction push-pull cylinder 202, and the drying control module. The drying control module is signal-connected to the air pump 302 and the heater 308.

[0079] In actual application scenarios, daily friction and water-washing friction usually occur alternately. In order to further improve the authenticity of the simulation and the accuracy of the test, in this embodiment, before conducting the durability test, the single dry friction time and the single washing friction time, as well as the number of alternating friction times can be reasonably set through the test setting module according to factors such as the application scenario and actual needs. When conducting the durability test, after the test piece is installed, the test control module will start the friction push-pull cylinder 202, so that the friction push-pull cylinder 202 drives the test piece to move back and forth to perform dry simulated friction treatment. After the dry simulated friction treatment time reaches the single dry friction time, the test control module will control the lifting cylinder 102 to drive the simulated friction component to move downward, so that the test piece is immersed in the washing water to perform water-washing simulated friction treatment. At the same time, the test control module will also send a heating instruction to the drying control module, so that the drying control module starts the heater 308 to heat the air in the heating cylinder 301. After the water-washing simulated friction treatment time reaches the single washing friction time, the test control module will control the lifting cylinder 102 to drive the simulated friction component to move downward, so that the test piece is immersed in the washing water to perform water-washing simulated friction treatment. The simulated friction component is driven to move upward to reset and close the friction push-pull cylinder 202. At the same time, the test control module will also send a drying instruction to the drying control module, causing the drying control module to start the air pump 302, so that the air pump 302 can transport the hot air in the heating cylinder 301 to the guide box 304, and spray the hot air to the test piece through the air guide hole 305 to dry the test piece (while the test control module starts the air pump 302, it still opens the solenoid valve 307 to replenish air into the heating cylinder 301). At this point, it is considered that one alternating friction is completed. After the test piece is dried, the test control module will start the friction push-pull cylinder 202 again to perform dry simulated friction treatment on the test piece, and repeat this process until the preset number of alternating frictions is completed. Therefore, through the joint setting of the baking cross component, the test intelligent control unit, etc., when conducting a durability test, the dry simulated friction treatment and the water-washing simulated friction treatment can be performed alternately, thereby further improving the authenticity of the simulation, and then further improving the accuracy of the test, while also greatly improving the automation and intelligence of the test.

[0080] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
