Description

Technical Field

[0001] This utility model relates to the field of nylon spinning production technology, and in particular to a one-to-one oiling pre-conditioning device for UV-resistant polyamide 6. Background Technology

[0002] In the production of UV-resistant polyamide 6 filament, oiling is necessary to reduce friction and static electricity, increase filament saturation, facilitate subsequent unwinding, reduce fuzz and breakage, and improve dyeing results. In the production of UV-resistant polyamide 6 filament, for products with a single fiber denier less than 0.6D and a yarn count exceeding 48F, the small filament fineness and large specific surface area make them prone to static electricity. Static electricity causes attraction or repulsion between fibers, affecting the uniform distribution of the oiling agent. As the single filament count increases, the total specific surface area of ​​the fibers also increases, leading to increased frictional resistance between fibers. An increased total specific surface area means enhanced adsorption of the oiling agent on the fiber surface, thus affecting the uniformity of oiling. Increased frictional resistance between fibers further increases the frictional resistance of the oiling agent, resulting in uneven oiling distribution.

[0003] Uneven oiling of UV-resistant polyamide 6 will increase the breakage rate of the yarn in subsequent production processes and affect the uniformity of dyeing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a one-to-one oiling pre-conditioning device for UV-resistant polyamide 6, which can ensure that a single yarn is fully wetted by the oiling agent, reducing the problem that the yarn with too high F number cannot be fully and evenly oiled.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a one-to-one oiling pre-conditioning device for UV-resistant polyamide 6, which is set between two oiling devices. The pre-conditioning device includes a mounting bracket, the length direction of which is parallel to the length direction of the oiling device. The mounting bracket is connected to a plurality of nozzles, each nozzle corresponding one-to-one with the number of filament bundles passing through the oiling device. The nozzles are fixed on the mounting bracket along the length direction of the mounting bracket. Each nozzle is connected to a branch pipe, and the branch pipes are connected to a main pipe, which is connected to an external air source.

[0007] Furthermore, the main pipeline is also equipped with a valve for adjusting the air pressure.

[0008] Furthermore, the distance between the nozzle orifice of the nozzle and the lower edge of the first oiling device is 10cm.

[0009] The advantages of this invention are as follows: by installing this device between the upper and lower oiling devices, the yarn is blown by air pressure to generate slight vibrations, which disrupts the yarn's arrangement order. This facilitates more thorough and even oiling of the yarn, reduces friction, and minimizes yarn damage, thereby ensuring production stability and high quality. Attached Figure Description

[0015] Please see Figures 1 to 2 This invention provides a one-to-one oiling pre-conditioning device 100 for UV-resistant polyamide 6, positioned between two oiling devices 200 arranged vertically. After the yarn bundles 1 requiring oiling pass through the oiling devices, the oil adheres to their surfaces. During oiling, several yarn bundles 1 pass through the oiling devices simultaneously, each yarn bundle 1 containing several monofilaments. For example, in the production of 20D48F yarn, several 20D48F yarns pass through the oiling devices simultaneously, each yarn (yarn bundle) containing 48 monofilaments. The pre-conditioning device includes a mounting bracket 2, the length of which is parallel to the length of the oiling devices. The mounting bracket 2 is connected to a plurality of nozzles 3, each nozzle 3 corresponding one-to-one with the number of yarn bundles 1 passing through the oiling devices, with the nozzle holes of the nozzles 3 facing the yarn bundles 1. Furthermore, the nozzles 3 are fixed to the mounting bracket 2 along its length. Each nozzle 3 is connected to a branch pipe 4, and the branch pipes 4 are all connected to a main pipe 5, which is connected to an external air source. The gas generated by the external air source is blown onto the yarn bundle 1 through the main pipe 5, branch pipes 4, and nozzles 3, causing the yarn bundle 1 to vibrate slightly, thus disrupting the yarn arrangement and making the oiling more thorough and even, reducing friction and yarn damage, thereby ensuring production stability and high quality.

[0016] Specifically, the main pipe 5 is also equipped with a valve 6 for adjusting the air pressure. By adjusting the opening of the valve 6, the flow rate of the gas blown from the nozzle 3 is adjusted, thereby adjusting the vibration of the filament bundle 1.

[0017] Specifically, the distance between the nozzle 3 orifice and the lower edge of the first oiling device is 10cm.

[0018] By installing this device between the upper and lower oiling devices, the yarn is blown by air pressure, generating slight vibrations that disrupt the yarn's arrangement. This allows for more thorough and even oiling of the yarn, reduces friction, and minimizes yarn damage, thereby ensuring production stability and high quality.

[0019] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
