[0020] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. Example

[0022] This embodiment provides a knitted fabric production process, comprising the following steps: S1. A blend of 50% polyester fiber and 49% cotton fiber is selected as the main fiber, and 1% nano-silver fiber masterbatch is added. The 50% polyester fiber can provide the fabric with sufficient strength, stiffness and wrinkle resistance, making it not easily damaged or deformed during daily wear and use, and can maintain a good appearance for a long time. The 49% cotton fiber mainly ensures the skin-friendliness of the fabric and provides a soft and comfortable wearing feel. At the same time, the nano-silver fiber masterbatch has strong antibacterial properties. Even if the addition amount is only 1%, it can effectively inhibit the growth of many common bacteria, fungi and other microorganisms. 1% nano-silver fiber masterbatch can not only exert its antibacterial effect, but also ensure the safety of the fabric. And a small amount of addition can avoid the potential health and environmental risks that may be caused by excessive nano-silver content, while helping to control costs.

[0023] S2, spinning polyester fiber and cotton fiber into yarn through a drawing frame; S3, dyeing the spun yarn; S4. Soak the dyed yarn in a fluorine-containing finishing agent for 45-90 minutes, and dry the yarn after soaking. If the time is shorter than 45 minutes, the fluorine-containing finishing agent cannot fully penetrate into the yarn and the fiber surface, and cannot form a complete and uniform protective film, resulting in poor water-repellent, oil-repellent and anti-fouling properties of the fabric. If the time exceeds 90 minutes, the yarn will excessively absorb the finishing agent, causing the yarn to become hard and the feel to deteriorate.

[0024] S5, weaving the dried yarn into a knitted fabric base material; S6. Soak the knitted fabric substrate in the fluorine-containing finishing agent again for 60-120 minutes. After the yarn is woven into the fabric, its structure becomes more compact and the pores between the fibers become smaller. This makes it more difficult for the fluorine-containing finishing agent to penetrate the interior of the fabric. Therefore, it takes longer to ensure that the finishing agent can fully cover the inner and outer surfaces of the fabric and form a complete water- and oil-repellent protective film.

[0025] S7, drying the soaked knitted fabric substrate through a drying device, and then rolling it up to finally obtain a knitted fabric.

[0026] In this embodiment, in step S3, the dyeing temperature is controlled at 80-95°C for 30-60 minutes, and 0.5%-1.5% of a leveling agent is added to the dye liquor. The added leveling agent allows the dye to be evenly adsorbed on the yarn during the dyeing process, avoiding problems such as uneven dyeing and color spots, improving dyeing uniformity and consistency, and making the fabric color more uniform and brighter.

[0027] It's important to note that temperatures below 80°C reduce the activity of the dye, preventing it from fully dissolving and diffusing into the fiber. This results in incomplete dyeing, pale, uneven colors, and compromised color fastness, with fading becoming more common. Temperatures above 95°C can damage fibers, especially cotton, reducing their strength and making them harder. Excessively high temperatures can also cause the dye to decompose or aggregate, resulting in color spots and other stains, affecting the appearance of the fabric.

[0028] If the dyeing time is shorter than 30 minutes, the dye will not have enough time to fully bond with the fiber, resulting in uneven dyeing, incomplete color, and reduced color fastness. If it exceeds 60 minutes, it will not only increase production costs and energy consumption, but may also cause excessive fiber swelling, affecting the dimensional stability of the fabric, and may cause excessive accumulation of dye on the fiber surface, affecting the dyeing effect and feel.

[0029] If the amount of leveling agent added is less than 0.5%, it will not be able to effectively improve the dispersibility and uniform adsorption of the dye, and problems such as uneven dyeing and color spots may easily occur; if the amount added is higher than 1.5%, it may affect the combination of dye and fiber, reducing the dyeing depth and color fastness.

[0030] In this embodiment, during the second soaking step S6, nano-titanium dioxide particles at a mass fraction of 0.2%-0.5% are added to the fluorine-containing finishing agent, allowing the nano-titanium dioxide particles to be incorporated into the fabric. Nano-titanium dioxide has photocatalytic properties, decomposing organic surface stains under the action of ultraviolet light, providing a self-cleaning function. It also absorbs ultraviolet light, providing UV protection, improving the fabric's weather resistance and service life, and protecting the wearer from UV damage.

[0031] It is worth noting that if the mass fraction of nano-titanium dioxide particles is less than 0.2%, their photocatalytic self-cleaning and UV protection effects cannot be fully exerted, and the self-cleaning and UV protection properties of the fabric are not obvious. If the mass fraction is higher than 0.5%, excessive nano-titanium dioxide particles may agglomerate on the fabric surface, affecting the feel and appearance of the fabric, while also increasing costs. Moreover, excessive content may pose potential risks to the environment and human health. Example

[0032] Based on Example 1, Figure 1-8This embodiment provides a knitted fabric production device, which includes a shell 1. A feed port 101 and a discharge port 102 are respectively provided on both sides of the shell 1. An extrusion chamber 103 is provided on the side of the shell 1 near the feed port 101, and a drying chamber 104 is provided on the side of the shell 1 near the discharge port 102. The extrusion chamber 103 and the drying chamber 104 are separated by a partition plate 105. A first guide roller 106, a second guide roller 107, a third guide roller 108, and a fourth guide roller 109 are sequentially provided inside the extrusion chamber 103, and the first guide roller 106, the second guide roller 107, the third guide roller 108, and the fourth guide roller 109 are all rotatably connected to the inner wall of the extrusion chamber 103.

[0033] The first guide roller 106 is equal to the second guide roller 107 in level, the third guide roller 108 is lower than the fourth guide roller 109 in level, the fourth guide roller 109 is lower than the first guide roller 106 in level, and an extrusion mechanism for extruding fabrics is also provided inside the extrusion chamber 103, and a plurality of guide rollers 110 are provided inside the drying chamber 104, and a drying mechanism is provided inside the drying chamber 104, and the drying mechanism includes a plurality of hot air blowers 4 arranged on the side of the shell 1.

[0034] The squeezing mechanism provided in this embodiment can squeeze out a large amount of moisture or finishing agent on the surface of the fabric, so that the moisture content of the fabric is greatly reduced before entering the drying chamber 104, thereby shortening the drying time of the fabric, improving the drying efficiency, and saving energy consumption.

[0035] Furthermore, the extrusion mechanism includes a supporting base plate 2, an extrusion roller 201, and a reciprocating drive assembly that drives the extrusion roller 201 to move back and forth on the surface of the supporting base plate 2. The supporting base plate 2 is arranged between the third guide roller 108 and the fourth guide roller 109, and the supporting base plate 2 is arranged at an angle. A plurality of support rods 202 are provided at the bottom of the supporting base plate 2, and each support rod 202 is fixedly connected to the bottom of the extrusion chamber 103. A plurality of through holes 203 are provided on the supporting base plate 2.

[0036] By providing a reciprocating drive assembly, the squeezing roller 201 can squeeze the fabric multiple times on the support base 2, thereby more fully squeezing out the moisture from the fabric and improving the fabric dehydration effect. The support plate 305 is tilted and provided with through holes 203 above it to facilitate the flow of moisture after it leaves the fabric, preventing moisture from accumulating on the support plate 305, thereby preventing moisture from being re-absorbed by the fabric and ensuring fabric dehydration efficiency.

[0037] Specifically, the reciprocating drive assembly includes a movable plate 204, a movable frame 205, a first rotating shaft 206, a rotating motor 207, and two first connecting rods 208. The squeezing roller 201 is rotatably connected to the movable frame 205. The movable plate 204 is arranged on the top of the movable frame 205 and is fixedly connected to the movable frame 205. The rotating motor 207 is arranged on the side of the shell 1 and is fixedly connected to the shell 1. The first rotating shaft 206 is fixedly connected to the output end of the rotating motor 207. A first opening 209 is provided on the side of the first rotating shaft 206 close to the movable plate 204. The two first connecting rods 208 are respectively arranged on both sides of the first opening 209 and are fixedly connected to the first rotating shaft 206. The opposite sides of the two first connecting rods 208 are connected to the second rotating shaft 210. A slide groove 211 is provided on the side of the movable plate 204 close to the second rotating shaft 210. The second rotating shaft 210 is slidably connected to the inner wall of the slide groove 211.

[0038] The movable plate 204 and the movable frame 205 are connected by a number of telescopic rods (telescopic rods typically include a fixed rod and a movable rod, which is well known to those skilled in the art and will not be described in detail here). Each telescopic rod is sheathed with an elastic member 5. Because the elastic member 5 always has the force to recover its deformation, it continuously applies force to the squeezing roller 201, thereby squeezing excess water out of the fabric and further improving the fabric dehydration efficiency.

[0039] During operation, the operator activates the rotary motor 207. The output of the rotary motor 207 drives the first rotating shaft 206 to rotate clockwise, which in turn drives the first connecting rod 208 to rotate clockwise. The first connecting rod 208, through transmission, causes the second rotating shaft 210 to rotate about the first rotating shaft 206. When the second rotating shaft 210 rotates half a turn clockwise, it moves downward within the chute 211. The first rotating shaft 206 pulls the movable plate 204 to the left, which in turn drives the movable frame 205, which in turn drives the squeezing roller 201 to move on the support base 2. As the second rotating shaft 210 continues to rotate clockwise, from half a turn to a full turn, it moves from the bottom of the chute 211 to the top of the chute 211, driving the movable plate 204 to the right, and thus the squeezing roller 201. This reciprocating motion completes the reciprocating motion of the squeezing roller 201 on the support base 2.

[0040] In this embodiment, the reciprocating drive assembly adopts a transmission mode in which the first connecting rod 208 and the slide groove 211 cooperate with each other, has a simple structure, is easy to manufacture and maintain, and can stably realize the reciprocating motion of the squeezing roller 201.

[0041] At the same time, the rotary motor 207 in this embodiment only needs to rotate in one direction to realize the reciprocating motion of the squeezing roller 201 , and does not need to be frequently rotated forward and reverse, thereby extending the service life of the rotary motor 207 .

[0042] When the squeezing roller 201 reciprocates under the action of the first connecting rod 208, the reciprocating path of the squeezing roller 201 is linear, while the support base 2 is tilted. This prevents the squeezing roller 201 from fully contacting the surface of the support base 2 (i.e., the surface of the fabric), thereby reducing the dehydration efficiency of the fabric. To avoid this, an inclined frame 212 is provided within the drying chamber 104, positioned above the support base 2. The inclined frame 212 is provided with a guide groove 213, which is tilted at an angle equal to the angle of inclination of the support base 2. A guide post 214 is fixedly connected to the top of the movable plate 204, and the guide post 214 is slidably connected to the inner wall of the guide groove 213.

[0043] By providing an inclined frame 212 and a guide groove 213 with the same inclination angle as the support base plate 2, the movable plate 204 can slide along the inner wall of the guide groove 213 during movement, thereby ensuring that the distance between the side surface of the squeezing roller 201 and the surface of the support base plate 2 remains unchanged during movement, thereby making the surface of the fabric evenly pressurized and ensuring the dehydration efficiency of the fabric.

[0044] Secondly, the guide groove 213 on the tilting frame 212 cooperates with the guide column 214 on the top of the movable plate 204, so that the movable plate 204 receives additional guidance and support during the reciprocating movement, further ensuring the stability and accuracy of the movement of the squeezing roller 201, thereby improving the uniformity of fabric extrusion.

[0045] In addition, the guide column 214 can be rotatably connected to the top of the movable plate 204, which can reduce the resistance encountered by the movable plate 204 during movement, reduce the occurrence of jamming, and thus improve the reliability and stability of the reciprocating drive assembly under long-term use.

[0046] In this embodiment, the movable frame 205 includes a fixed section 2041 and a movable section 2042. The fixed section 2041 is fixedly connected to the movable frame 205. An extension block 2043 is provided on the top of the fixed section 2041. A receiving groove 2044 is provided on the movable section 2042. The extension block 2043 is slidingly connected to the inner wall of the receiving groove 2044. A fixing component for fixing the extension block 2043 is provided in the receiving groove 2044. The fixing component includes a fixing bolt 2045 and a gasket 2046. An adjustment groove 2047 is provided on one side of the receiving groove 2044. One side of the fixing bolt 2045 is threadedly connected to the extension block 2043. The width of the adjustment groove 2047 is greater than the diameter of the fixing bolt 2045. The gasket 2046 is arranged between the bolt head of the fixing bolt 2045 and the side of the movable section 2042.

[0047] Through the design of the fixed section 2041, the movable section 2042, the extension block 2043 and the fixing assembly, the user can conveniently adjust the position of the extrusion roller 201 according to the thickness, material and other requirements of the fabric, so as to achieve the best extrusion effect and improve the applicability and flexibility of the extrusion mechanism, thereby meeting the production requirements of various knitted fabrics.

[0048] When the user needs to adjust the height of the extrusion roller 201, the fixed bolt 2045 can be loosened with a tool, so that the head of the bolt is separated from the side surface of the movable section 2042. Then, the user can pull down the movable section 2042, so that the extension block 2043 moves in the accommodating groove 2044, and the extrusion roller 201 adjusts the position along with the movement of the movable section 2042. When the position is adjusted to the appropriate position, the user can tighten the fixed bolt 2045 with a tool, so that the side surface of the threaded head is in contact with the side surface of the movable section 2042, and the extension block 2043 is fixed by the friction principle. The fixing assembly in the embodiment can fix the extension block 2043 at any position in the adjusting groove 2047, thereby expanding the use range and further improving the applicability and flexibility of the extrusion mechanism.

[0049] In the embodiment, a beating mechanism is arranged between the first guide roller 106 and the second guide roller 107. The beating mechanism comprises a support frame 3 fixedly connected with the inner wall of the extrusion chamber 103, a beating plate 301 rotationally connected with the support frame 3, a second connecting rod 302, two third connecting rods 304, a third rotating shaft 303, and a power assembly for driving the third rotating shaft 303 to rotate. The beating plate 301 should be arranged at the bottom of the first guide roller 106 (i.e. the bottom of the fabric). The third rotating shaft 303 is rotationally connected with the inside of the drying chamber 104 through a plurality of support plates 305. The side of the third rotating shaft 303 close to the beating plate 301 is provided with a second opening 306. The two third connecting rods 304 are arranged on the two sides of the second opening 306 and are fixedly connected with the third rotating shaft 303. One end of the second connecting rod 302 is rotationally connected with the third connecting rod 304, and the other end of the second connecting rod 302 is rotationally connected with the beating plate 301. The length of the third connecting rod 304 is less than the length of the second connecting rod 302.

[0050] Specifically, the power assembly comprises a first bevel gear 307 and a second bevel gear 308. The first bevel gear 307 is fixedly connected with the third rotating shaft 303, and the second bevel gear 308 is fixedly connected with the first rotating shaft 206. The first bevel gear 307 is engaged with the second bevel gear 308.

[0051] Through the beating of the beating mechanism on the fabric, the excess water on the surface of the fabric can be separated, thereby reducing the excess water on the surface of the fabric to a certain extent, reducing the burden of the subsequent extrusion mechanism, making the drying process more efficient, and saving energy and time.

[0052] When the first rotating shaft 206 rotates under the driving of the rotating motor 207, the second bevel gear 308 on the first rotating shaft 206 also rotates, thereby driving the first bevel gear 307 to rotate. The first bevel gear 307 drives the third rotating shaft 303 to rotate, the third rotating shaft 303 drives the second connecting rod 302 to rotate, and the other end of the second connecting rod 302 drives one end of the third connecting rod 304 to rotate around the third rotating shaft 303. At the same time, the other end of the third connecting rod 304 drives the beating plate 301 to swing around the support frame 3, so as to beat the bottom of the cloth.

[0053] The first bevel gear 307 and the second bevel gear 308 are arranged in the embodiment, the rotating motor 207 in the pressing mechanism is ingeniously used to provide rotating power for the third rotating shaft 303, so that the power assembly does not need to additionally arrange a power source, the equipment structure is simplified, and the production cost is reduced.
