Abstract
Description
Technical Field
[0001] This invention relates to the field of fabric research and development technology, and in particular to a processing equipment and research and development process for chemical protective clothing fabric. Background Technology
[0002] Currently, the known chemical protective suits include rubber sheet isolation suits, oilcloth isolation suits, and butyl rubber sheet one-piece chemical protective suits. All of these are isolation-type protections, which do not allow sweat to pass through. If toxic gas enters the clothing, it can cause harm to the person. All of these suits allow human sweat to accumulate inside the clothing. After use, several kilograms of sweat can be stored inside the clothing, which may also cause shock to personnel. The working time for wearing them at one time is short, and toxic gas can damage the skin of the personnel.
[0003] In the prior art, Chinese patent document CN2442688Y discloses a protective firefighting suit with multiple functions, including flame retardancy, waterproofing, barrier protection against toxic gases, gas absorption, and breathability. It is a functional garment made of flame-retardant fabric, polytetrafluoroethylene microporous membrane, activated carbon fabric, and lining fabric, all sewn together. Its protective measures employ three methods: the fabric is non-stick to toxic substances, the polytetrafluoroethylene microporous membrane isolates toxic substances, and activated carbon cloth adsorbs toxic substances. A large amount of sweat emitted by the human body can be expelled unidirectionally from the inside out, ensuring the wearer does not feel damp. This can increase working time several times over and improve combat effectiveness. However, as the name suggests, chemical protective clothing primarily serves a protective function, used in emergency and major accident scenes and environments with abundant toxic gases. Its main function is to protect the skin and respiratory system of workers and rescue personnel from the harmful effects of toxic gases. Therefore, researching a high-strength, high-adsorption-value chemical protective clothing fabric is particularly necessary. Thus, this application proposes a chemical protective clothing fabric processing equipment and research and development process to meet the research and development needs of improving the strength and adsorption capacity of chemical protective clothing fabric.

The tilting frame includes a seat and a rubber strip arranged within the tilting seat for pressing the end of the knitted fabric. An inclined spring is also connected between the tilting seat and the rubber strip, with both ends of the inclined spring connected to the corresponding rubber strip and the tilting seat. The tumbling frame is also provided with a perforation assembly for needle-punching the knitted fabric. The perforation assembly includes multiple fixed plates installed within the tumbling frame and needles arranged on the fixed plates. An extension seat is also connected to one side of the perforation plate. A vertical spring is also connected between the extension seat and the fixed plate, and multiple through holes corresponding to the positions of the needles are opened on the perforation plate.
[0006] Preferably, a central shaft is fixedly sleeved on the tumbling frame and arranged coaxially therewith. Both ends of the central shaft are rotatably mounted on the bracket. The motor is mounted on the bracket, and pulleys are fixedly sleeved on the output end of the motor and one end of the central shaft. The same transmission belt is tensioned on the two pulleys.
[0007] Preferably, the fixed panel has an extension hole, the perforated plate is located in the corresponding extension hole, and the tilting seat is fixedly installed at one end of the corresponding perforated plate. The bottom width of the tilting seat is greater than the top width of the tilting seat, and one side of the tilting seat is tilted.
[0008] Preferably, an inclined guide rod is slidably sleeved on the inclined seat, one end of the rubber strip is fixedly connected to one end of the corresponding inclined guide rod, the other end of the inclined guide rod is fixedly sleeved with a pull cap, and the inclined spring is sleeved on the corresponding inclined guide rod.
[0009] Preferably, the extension seat is fixedly connected to one side of the perforated plate and located inside the tumbling frame, and a plurality of guide rods are fixedly connected to the inner wall of the fixed panel, and the extension seat is slidably sleeved on the corresponding guide rods.
[0010] Preferably, the vertical spring is sleeved on the corresponding guide rod, and the two ends of the vertical spring are respectively connected to the corresponding extension seat and the fixed panel.
[0011] Preferably, a plurality of evenly distributed connecting rods are connected to the central shaft, and the fixing plate is fixedly connected to the other end of the corresponding connecting rod, and the fixing plate is located on one side of the corresponding perforation plate.
[0012] Preferably, the top of the bracket is also rotatably connected to a flip cover via a hinge, and a partition is installed inside the flip cover, with the partition located on one side of the motor.
[0013] A research and development process for a chemical protective suit fabric, specifically applied to the processing equipment for the aforementioned chemical protective suit fabric, includes the following steps: S1. Selection of raw materials: 200D-450D viscose-based filaments are selected as raw materials; S2. Manufacturing process: The fabric is made by knitting, with a width of 1700mm-2000mm and a weight of 220g / m2-350g / m2. S3. Cleaning: The fabric obtained in step S2 is cleaned with distilled water. S4. Immersion in flame retardant: Phosphate is selected as the flame retardant, and an impregnation solution is prepared according to the weight ratio of water to 5%-10%. The knitted fabric is then immersed in the impregnation solution for 15-30 minutes using chemical protective clothing fabric treatment equipment. After squeezing out the water, it is then dried. S5. Low-temperature carbonization treatment: The carbonization unit is 15m-20m long and divided into three temperature zones. The temperature of zone one is set at 200℃-240℃, the temperature of zone two is set at 240℃-280℃, and the temperature of zone three is set at 280℃-350℃. Under tension, the fabric is pulled at a speed of 1m / min-5m / min, and the yield is controlled between 50% and 55%. S6. High-temperature carbonization and activation: The carbonized cloth is pulled into a continuous high-temperature carbonization and activation unit. The carbonization unit is 9m-15m long and divided into three temperature zones: Zone 1 is set at 700℃-850℃, Zone 2 at 850℃-950℃, and Zone 3 at 850℃-950℃. Under tension, the cloth is pulled at a speed of 1m / min-5m / min. It is further purified by high-temperature carbonization and then activated at high temperature. The yield is controlled between 16% and 20%.
[0014] The beneficial effects of this invention are: 1. The processing equipment and R&D process for this type of chemical protective clothing fabric involves placing the end of the knitted fabric to be immersed in a corresponding inclined seat. The inclined springs and rubber strips then secure the end of the knitted fabric, maintaining its tension and promoting thorough immersion of the flame retardant. The inclined seats also facilitate the lifting of the rubber strips during fabric placement, securing the fabric. A motor drives the central shaft and tumbling frame to rotate synchronously, intermittently immersing the knitted fabric in the lower reservoir. This enhances the flame retardant immersion effect and optimizes the subsequent performance of the knitted fabric.
[0015] 2. The processing equipment and R&D process for this type of chemical protective clothing fabric, when the knitted fabric is laid on the corresponding perforated plate, can further press the knitted fabric after the ends of the knitted fabric are clamped by rubber strips at both ends. Under the guidance of the guide rod, the corresponding perforated plate moves closer to the center of the tumbling frame. Combined with the penetrating action of the needles on the fixed plate, one end of the needle penetrates the fixed plate and the knitted fabric, leaving a hole in the knitted fabric. This promotes the flame retardant to enter the interior of the knitted fabric during the subsequent immersion process, further optimizing the flame retardant effect of the knitted fabric and thus improving the practicality of the chemical protective clothing.
[0016] 3. The processing equipment and R&D process for this type of chemical protective clothing fabric improve the high-temperature resistance of the knitted fabric, making it more suitable for use in high-temperature environments. The fiber structure in the fabric is strengthened, and the mechanical strength and abrasion resistance are improved, making it more durable and suitable for some high-strength requirements. The surface properties of the fabric can be changed to give it certain conductivity, adsorption, and optical properties, thereby expanding its application possibilities in specific fields. The treated fabric has better dimensional stability and thermal stability, is not easily deformed or thermally expanded, and is suitable for special industrial and application environments, with a wider range of application prospects.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] like Figures 2-7As shown, the chemical protective clothing fabric processing equipment includes a tumbling frame 2 rotatably mounted within a support 1. The support 1 also contains a storage tank for storing flame retardant, with the tumbling frame 2 partially submerged in the storage tank. A drive assembly for rotating the tumbling frame 2 is also mounted on the support 1, including a motor 9. Multiple evenly distributed fixed panels 3 and perforated plates 4 are also mounted on the tumbling frame 2, with the same set of fixed panels 3 and perforated plates 4 corresponding to each other. The fixed panels 3 also have positioning components for fixing the knitted fabric, including components mounted on the corresponding perforated plates 4. The tilting seat 5 and the rubber strip 6 arranged in the tilting seat 5 for pressing the end of the knitted fabric are provided. A tilting spring is also connected between the tilting seat 5 and the rubber strip 6, with the two ends of the tilting spring connected to the corresponding rubber strip 6 and the tilting seat 5 respectively. The tumbling frame 2 is also provided with a perforation assembly for needle-punched knitted fabric. The perforation assembly includes multiple fixed plates 14 installed in the tumbling frame 2 and needles 15 arranged on the fixed plates 14. An extension seat 10 is also connected to one side of the perforation plate 4. A vertical spring 12 is also connected between the extension seat 10 and the fixed panel 3. The perforated plate 4 has multiple through holes corresponding to the positions of the needles 15. When the knitted fabric needs to be immersed in the flame retardant, the ends of the knitted fabric to be immersed are clamped in the positioning component to keep the knitted fabric taut, thereby promoting the full immersion of the flame retardant. At the same time, the inclined seat 5 facilitates the lifting of the rubber strip 6 to fix the knitted fabric. The drive component pulls the tumbling frame 2 to continuously rotate, thereby causing the knitted fabric on it to be intermittently immersed in the reservoir below, promoting the immersion effect of the flame retardant. The performance of the subsequent knitted fabric is optimized. In addition, when the knitted fabric is laid on the corresponding perforated plate 4, after the ends of the knitted fabric are clamped by the rubber strips 6 at both ends, the knitted fabric is pressed again, so that the corresponding perforated plate 4 moves closer to the center of the tumbling frame 2. With the penetrating effect of the needles 15 on the fixing plate 14, one end of the needles 15 penetrates the fixing plate 14 and the knitted fabric. This promotes the flame retardant to enter the interior of the knitted fabric during the subsequent immersion process, further optimizing the flame retardant effect of the knitted fabric and thus improving the practicality of the chemical protective clothing.
[0023] Further, see attached document. Figures 2-5A central shaft 8, coaxially arranged, is fixedly sleeved on the rolling frame 2. Both ends of the central shaft 8 are rotatably mounted on the bracket 1. A motor 9 is mounted on the bracket 1, and pulleys are fixedly sleeved on both the output end of the motor 9 and one end of the central shaft 8. The same transmission belt is tensioned on the two pulleys. An extension hole is provided on the fixed panel 3, and a perforated plate 4 is located in the corresponding extension hole. An inclined seat 5 is fixedly installed on one end of the corresponding perforated plate 4. The bottom width of the inclined seat 5 is greater than the top width of the inclined seat 5, and one side of the inclined seat 5 is inclined. An inclined guide rod is also slidably sleeved on the inclined seat 5. One end of a rubber strip 6 is fixedly connected to one end of the corresponding inclined guide rod, and a pull cap 7 is fixedly sleeved on the other end of the inclined guide rod. An inclined spring is sleeved on the corresponding inclined guide rod, and the two ends of the inclined spring are respectively Connected to the corresponding rubber strip 6 and tilting seat 5, when the knitted fabric needs to be immersed in the flame retardant, the end of the knitted fabric to be immersed is placed in the corresponding tilting seat 5, and the end of the knitted fabric is fixed by the rubber strip 6 through the elastic force of the tilting spring, so that the knitted fabric is kept taut, thereby promoting the subsequent immersion of the flame retardant. At the same time, the tilting seat 5 makes it easy to lift the rubber strip 6 when placing the fabric to complete the fixing operation of the knitted fabric. After the motor 9 is turned, the transmission belt and pulley drive the central shaft 8 and the tumbling frame 2 to rotate synchronously and continuously, thereby causing the knitted fabric on it to be intermittently immersed in the reservoir below, promoting the immersion effect of the flame retardant and optimizing the performance of the knitted fabric.
[0024] Further, see attached document. Figure 6 An extension seat 10 is fixedly connected to one side of the corresponding perforated plate 4 and located inside the tumbling frame 2. Multiple guide rods 11 are fixedly connected to the inner wall of the fixed panel 3. The extension seat 10 is slidably sleeved on the corresponding guide rod 11. A vertical spring 12 is sleeved on the corresponding guide rod 11, and both ends of the vertical spring 12 are respectively connected to the corresponding extension seat 10 and the fixed panel 3. Multiple evenly distributed connecting rods 13 are also connected to the central shaft 8. A fixed plate 14 is fixedly connected to the other end of the corresponding connecting rod 13, and the fixed plate 14 is located on one side of the corresponding perforated plate 4. The knitted fabric surface... When the material is laid on the corresponding perforated plate 4, after the ends of the knitted fabric are clamped by the rubber strips 6 at both ends, the knitted fabric is pressed again. Under the guidance of the guide rod 11, the corresponding perforated plate 4 moves closer to the center of the tumbling frame 2. With the penetrating action of the needles 15 on the fixing plate 14, one end of the needles 15 penetrates the fixing plate 14 and the knitted fabric, leaving a hole in the knitted fabric. This promotes the flame retardant to enter the interior of the knitted fabric during the subsequent immersion process, further optimizing the flame retardant effect of the knitted fabric and thus improving the practicality of the chemical protective clothing.
[0025] Further, see attached document. Figure 1The top of the bracket 1 is also connected to a flip cover 16 by a hinge. A partition 17 is installed inside the flip cover 16. The partition 17 is located on one side of the motor 9. By setting the flip cover 16, splashing is prevented when the flame retardant is immersed in the rotation. By setting the partition 17, the flame retardant is prevented from splashing onto the motor 9.
