Description

[Technical field]

[0001] The present invention relates to the technical field of PE (polyethylene) spun yarn, and more particularly to a 100% PE spun yarn having anti-fuzzing and anti-pilling properties and a method for producing the same. [Background technology]

[0002] Currently, in the market, fabrics made of spun yarn for clothing, accessories, etc., when subjected to friction or other forces during use, due to the strength of the yarn, single fibers will break. After breaking, the roots of the yarns will still be present in the fabric, and will become entangled with each other after friction to form small yarn balls, which will reduce the comfort of the fabric and affect its appearance.

[0003] Conventional technology mainly solves the problems of pilling and fuzzing by improving the entanglement of the tow (fibers) through twisting (applying twist to the yarn). However, adding this process increases production costs, makes the fabric feel hard, and because of the twist, the fabric surface is rough and uneven, with a dull luster. Summary of the Invention [Problem to be solved by the invention]

[0004] In response to the deficiencies of the prior art, we provide 100% PE spun yarn with anti-fuzzing and anti-pilling properties and its manufacturing method. By improving the molecular weight size of the fiber, the tensile process, the strength, elongation and cross-section of the single fiber, we have effectively solved the problem of single fiber breakage during the use of the fabric, fundamentally solved the problem of fuzzing, and further prevented the occurrence of pilling problems. [Means for solving the problem]

[0005] The technical solution used in the present invention to solve this technical problem is a method for producing 100% PE spun yarn that is resistant to fluff and pilling. The dried polyolefin chips are put into the raw material input chamber, first melted, filtered and weighed, then put into the heat-insulating box, then filtered and pressurized by the component, and then uniformly extruded from the spinneret, so that the melting temperature range is 270-290°C, the box temperature is 285-300°C, 80-100 mesh stainless steel sintered metal sand is filled inside the component, and the initial pressure of the component is 110KG. Spinning step S1; A cooling step S2 in which the dropped tow is cooled by air to a focusing point, and the air temperature is set to 16 to 18°C ​​and the air speed is set to 0.6 to 0.75 m / s; The tow that falls from the cooling window is oiled by an oiling wheel, and then the tow is put into the hot stretching section and pulled. The oiling wheel speed is 32-35HZ, the oil concentration is 1:6, the oiling rate of the tow is 1.1-1.3%, the stretching ratio is 4.6-4.9, and the stretching temperature is 62-70°C. In the oiling-stretching step S3, and a shaping and winding step S4 in which the tow after pulling is stably shaped and wound, the shaping temperature is set to 108 to 110°C, and the boiling water shrinkage rate of the tow after shaping is set to 8% to 9%.

[0006] Specifically, the molecular weight of the polyolefin chip is 680,000 to 750,000.

[0007] Specifically, in step S1, 110 to 120 g of sintered stainless steel metal sand is loaded inside the component.

[0008] Specifically, in step S1, the melting temperatures are set as 270°C, 290°C, 290°C and 290°C, and the box temperature is 290°C.

[0009] Specifically, the shape of the spinning holes on the spinneret is triangular or rectangular.

[0010] Specifically, in step S2, the distance from the convergence point to the spinneret is 2 to 2.3 m.

[0011] Specifically, in step S3, the oil coating rate of the tow is controlled to 1.2%.

[0012] Specifically, in step S4, the number of windings is 6 to 8.

[0014] Specifically, 100% PE spun yarn, which has anti-fuzzing and anti-pilling properties, has a single fiber fineness of 6D. Effect of the Invention

[0015] Compared with the prior art, the advantages of the present invention using the above technical solution are: First, the present invention improves the toughness index of single fibers by adjusting the process parameters of each process of spinning, cooling, oiling and drawing, and shaping and winding, effectively solving the problem of single fibers breaking during the use of the fabric, fundamentally solving the problem of fluffing, and further preventing the occurrence of pilling problems.

[0016] The following examples are provided to clearly and completely illustrate the technical solutions of the embodiments of the present invention. Of course, the described examples are only a part of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, any other embodiments that a person skilled in the art can obtain without inventive efforts are within the scope of protection of the present invention.

[0017] The manufacturing method of 100% PE spun yarn with anti-fuzzing and anti-pilling properties is as follows: The dried polyolefin chips are put into the raw material input chamber, first melted, filtered and weighed, then put into the heat-insulating box, then filtered and pressurized by the component, and then uniformly extruded from the spinneret, so that the melting temperature range is 270-290°C, the box temperature is 285-300°C, 80-100 mesh stainless steel sintered metal sand is filled inside the component, and the initial pressure of the component is 110KG. Spinning step S1; A cooling step S2 in which the dropped tow is cooled by air to a focusing point, and the air temperature is set to 16 to 18°C ​​and the air speed is set to 0.6 to 0.75 m / s; The tow that falls from the cooling window is oiled by an oiling wheel, and then it is put into the hot drawing section for pulling and drawing. The speed of the oiling wheel is 32-35HZ, the concentration of the oil agent is 1:6, the oiling rate of the tow is 1.1-1.3%, the pulling ratio is 4.6-4.9, and the drawing temperature is 62-70°C. The oiling and drawing step S3, in which the concentration of the oil agent refers to the ratio of the oil agent to the spinning solution, and a shaping and winding step S4 in which the tow after pulling is stably shaped and wound, the shaping temperature is set to 108 to 110°C, and the boiling water shrinkage rate of the tow after shaping is set to 8% to 9%.

[0018] By adjusting the temperature of the spinning process, the component loading process is optimized to ensure that the fiber yarn is extruded continuously and uniformly, by adjusting the cooling air temperature and speed, the tow is cooled uniformly, the tow is stabilized, and the tow swing width is reduced, by adjusting the oiling wheel speed and oiling concentration, the tow is controlled to a suitable oiling rate, by adjusting the tension ratio and tension temperature, the fuzz is removed and the tow is not wound on the roll, and the boiling water shrinkage is reduced to 8%-9% to achieve stable shaping. The present invention improves the toughness index of single fiber by optimizing the process parameters of each process of spinning, cooling, oiling and drawing, and shaping and winding, effectively solving the problem of single fiber breakage during the use of the fabric, fundamentally solving the problem of fuzzing, and preventing the occurrence of pilling problems.

[0019] In one embodiment, the molecular weight of the polyolefin chip is 680,000 to 750,000. The use of ultra-high molecular weight polyethylene helps to improve the strength of the single fiber.

[0020] In one embodiment, in step S1, 110-120g of stainless steel sintered metal sand is loaded into the component. Optimizing the component loading process helps to extrude the fiber yarn continuously and uniformly.

[0021] In one embodiment, in step S1, the melt temperatures are set as 270°C, 290°C, 290°C and 290°C, and the box temperature is 290°C.

[0023] In one embodiment, in step S2, the distance from the convergence point to the spinneret is 2 to 2.3 m. An appropriate distance allows both the cooling effect of the tow and the stabilization of the tow to be achieved. If the distance is too short, the tow will not be cooled sufficiently, but if the distance is too long, the swing width of the tow will be large.

[0024] In one embodiment, the oiling rate of the tow is controlled to 1.2% in step S3. Uniform and proper oiling provides a foundation for drawing and facilitates stable shaping.

[0025] In one embodiment, in step S4, the number of windings is 6 to 8. A constant number of windings can increase the forming time, which is helpful for stable forming of the tow.
