Description

A special polyester filament fiber with super cotton-like texture Technical Field

[0001] This invention relates to the field of filament fiber technology, specifically to a special polyester filament fiber that mimics cotton. Background Technology

[0002] Fibers are substances composed of continuous or discontinuous filaments, and are divided into two main categories: natural fibers and chemical fibers. Natural fibers include plant fibers (cotton, linen), animal fibers (wool, silk), and mineral fibers (asbestos); chemical fibers include man-made fibers (viscose fiber), synthetic fibers (polyester, nylon), and inorganic fibers (glass fiber).

[0003] The method for preparing a super-imitation cotton filament described in patent application CN108374210B belongs to the field of textile material technology. The method prepares polyester filament by melt spinning and uses it as the core layer of the imitation cotton filament. A dissolved cellulose solution is coated on the surface of the polyester filament by an oil pump as the skin layer of the imitation cotton filament. Finally, the super-imitation cotton filament is obtained by coagulation bath-drying.

[0004] Currently, the common operating method is to directly place the winding bar containing long-filament polyester onto the fixed post, with the bottom of the winding bar placed on the workbench. However, this traditional method has many drawbacks.

[0005] During the textile process, as the filament polyester fibers are continuously pulled out, significant frictional resistance is generated between the winding bar and the worktable. This frictional resistance not only makes the yarn output process less smooth and affects work efficiency, but also causes wear and tear on the bottom of the winding bar after prolonged use. Once the bottom of the winding bar is worn, its surface becomes rough, making it prone to scratching the filament polyester fibers during the yarn output process, leading to a decline in fiber quality and ultimately affecting the quality of the final textile product. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a super-cotton-like special polyester filament fiber, thereby achieving the goal of solving the aforementioned problems.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a super-imitation cotton special polyester filament fiber, characterized in that the fiber is a polyethylene terephthalate filament with an irregular cross-section, a single filament fineness of 0.8 dtex to 1.5 dtex, a moisture absorption rate of 2.5% to 8.0%, a resistivity of 10^8 Ω·g / cm² to 10^10 Ω·g / cm², and a crimp elastic recovery rate of not less than 85% measured under standard temperature and humidity conditions, wherein the fiber is wound onto various winding bars.

[0008] The top of the winding bar is provided with a rotating wire output mechanism;

[0009] The rotating cable exit mechanism includes:

[0010] The fixing sleeve is a ring-shaped structure. The bottom of the fixing sleeve is fixedly connected to the top of the winding bar. A threaded strip is fixedly connected to the outer wall of the fixing sleeve, and a through hole is opened on the inner wall of the winding bar.

[0011] A threaded cap, which is a circular sleeve structure, has a threaded groove on its inner wall, and is threadedly connected to a threaded bar through the threaded groove.

[0012] Preferably, a clamping push block is slidably connected to the inner wall of the winding bar, and a first spring is fixedly connected to one end of the clamping push block.

[0013] Preferably, one end of the first spring is fixedly connected to the inner wall of the winding bar, and a long block is fixedly connected to one side of the clamping push block.

[0014] Preferably, the long block is rotatably connected to a rolling ball, and the upper and lower positions of the long block are inclined surfaces.

[0015] Preferably, there are four rolling balls on one side of the long block, and the four rolling balls are equidistantly distributed in the inner wall of the long block.

[0016] Preferably, an auxiliary mechanism is fixedly connected to the top of the threaded cap, the auxiliary mechanism including a fixing block, the bottom of the fixing block being fixedly connected to the top of the threaded cap.

[0017] Preferably, a connecting seat is fixedly connected to the top of the fixed block, a lifting sliding block is slidably connected to the inner wall of the connecting seat, and a scale groove is formed on the outer wall of the lifting sliding block.

[0018] Preferably, a second spring is fixedly connected to the bottom of the scale groove, and one end of the second spring is fixedly connected to the bottom of the inner wall of the connecting seat.

[0019] This invention provides a super-imitation cotton specialty polyester filament fiber. It possesses the following beneficial effects:

[0020] 1. This invention, by setting up a rotating lead-out mechanism, allows the winding bar to rotate relative to the inserted rod or column via a bearing disc on the inner wall of the upper threaded cover. This enables the winding bar to be lifted by the rod while smoothly rotating and leading out the wire. Compared with the traditional method where the winding bar is fitted onto a column but its bottom rests on the table surface, this reduces frictional resistance, improves the smoothness of lead-out and work efficiency, and avoids the problem of fiber quality degradation caused by bottom wear. It also avoids the problem of uneven work surface causing the winding bar to shake during rotation, affecting the stability of lead-out.

[0021] 2. This invention sets up a rotating lead-out mechanism, which uses the rebound force of the first spring to press the column tightly, and uses three long blocks to ensure the stability and coaxiality of the perforation on the inner wall of the winding bar when it is fitted onto the column or rod. This effectively prevents eccentricity or loosening during rotation, and ensures that the filament fiber maintains uniform tension and runs smoothly during high-speed unwinding, further improving the quality of textiles and production efficiency.

[0022] 3. By setting up a rotating lead-out mechanism, when the fiber thread outside the winding bar is pulled and the winding bar rotates through the threaded cover and bearing disc, the winding bar will also rotate freely through the internal rolling ball. This achieves mutual rotation with the column surface without interference, further reducing internal frictional resistance, avoiding fiber tension fluctuations caused by jamming, and ensuring a smooth and stable unwinding process. At the same time, the rolling action of the rolling ball effectively disperses stress, reduces the risk of local wear, extends the overall service life of the winding bar, and ensures the consistency of fiber quality under long-term continuous production.

[0023] 4. By setting up an auxiliary mechanism, the lifting sliding block continuously increases its descent height as the rotation speed increases. Furthermore, through the positional relationship between the scale groove on the outer wall of the lifting sliding block and the connecting seat, the operator can intuitively observe the degree of descent of the lifting sliding block, thereby judging the current rotation speed and realizing real-time monitoring and adjustment of the unwinding tension. This ensures that the fiber tension is always within the ideal range during the production process, improving spinning precision and product consistency. Attached Figure Description

[0033] Example 1: Please refer to Figures 1-3. The present invention provides a technical solution: a super cotton-like special polyester filament fiber, characterized in that the fiber is a polyethylene terephthalate filament with an irregular cross section, the single filament fineness is 0.8 dtex~1.5 dtex, the moisture absorption rate of the fiber is 2.5%~8.0%, the resistivity is 10^8 Ω·g / cm²~10^10 Ω·g / cm², and the fiber crimp elastic recovery rate measured under standard temperature and humidity conditions is not less than 85%. The fiber is wound onto each winding bar 2.

[0034] The top of the winding rod 2 is equipped with a rotating wire output mechanism 3;

[0035] The rotating cable exit mechanism 3 includes:

[0036] The fixing sleeve 301 is a ring-shaped sleeve structure. The bottom of the fixing sleeve 301 is fixedly connected to the top of the winding bar 2. A threaded strip 302 is fixedly connected to the outer wall of the fixing sleeve 301. A through hole 305 is opened on the inner wall of the winding bar 2.

[0037] The threaded cover 303 is a circular sleeve structure. The inner wall of the threaded cover 303 is provided with a threaded groove 304. The threaded cover 303 is threadedly connected to the threaded strip 302 through the threaded groove 304.

[0038] When in use, the long filament polyester yarn is wound on the winding bar 2 and used. The perforation 305 on the inner wall of the winding bar 2 is fitted onto a rod or column. As the textile work proceeds, the long filament polyester fibers on the winding bar 2 are continuously pulled out. The winding bar 2 rotates with the inserted rod or column through the bearing disc 306 on the inner wall of the upper threaded cover 303. This allows the winding bar 2 to be lifted by the rod and rotate smoothly to produce yarn. Compared with the traditional method of fitting the winding bar 2 onto a column but with the bottom of the winding bar 2 resting on the table, this method reduces frictional resistance, improves the smoothness of yarn production and work efficiency, and avoids the problem of fiber quality degradation caused by bottom wear. It also avoids the problem of the winding bar 2 shaking during rotation and affecting the stability of yarn production due to uneven work surface.

[0039] Example 2: Please refer to Figures 1-6. Based on Example 1, the present invention provides a technical solution: a clamping push block 308 is slidably connected to the inner wall of the winding bar 2, and a first spring 307 is fixedly connected to one end of the clamping push block 308.

[0040] One end of the first spring 307 is fixedly connected to the inner wall of the winding bar 2, and a long block 310 is fixedly connected to one side of the clamping push block 308.

[0041] The long block 310 is rotatably connected to the rolling ball 309, and the upper and lower positions of the long block 310 are inclined surfaces.

[0042] There are four rolling balls 309 on one side of the long block 310, and the four rolling balls 309 are equidistantly distributed in the inner wall of the long block 310.

[0043] When the winding bar 2 is fitted onto the post, the post passes through the perforation 305 on the inner wall of the winding bar 2 and contacts the inclined surface at the bottom of the long block 310, pushing the long block 310 to slide into the inner wall of the winding bar 2 and compressing the first spring 307 to deform it. This causes the long block 310 and the clamping push block 308 to penetrate into the inner wall of the winding bar 2. The rebound force of the first spring 307 is used to press the post tightly. The three long blocks 310 ensure the stability and coaxiality of the perforation 305 on the inner wall of the winding bar 2 when it is fitted onto the post or bar, effectively preventing eccentricity or loosening during rotation. This ensures that the filament fiber maintains uniform tension and runs smoothly during high-speed unwinding, further improving the quality of textiles and production efficiency.

[0044] Furthermore, when pushing open the long block 310, it will contact the rolling ball 309 on each long block 310. Through the rolling of the rolling ball 309, the rod will be pushed upward steadily and smoothly along the surface of the rolling ball 309 and the long block 310, thereby reducing insertion resistance and improving assembly smoothness. The setting of the rolling ball 309 also allows the winding rod 2 to rotate through the threaded cover 303 and bearing disk 306 when the fiber thread outside the winding rod 2 is pulled. The free rolling of the internal rolling ball 309 allows the winding rod 2 to rotate without interfering with the mutual rotation of the column surface, further reducing internal frictional resistance, avoiding fiber tension fluctuations caused by jamming, and ensuring a smooth and stable unwinding process. At the same time, the rolling action of the rolling ball 309 effectively disperses stress, reduces the risk of local wear, extends the overall service life of the winding rod 2, and ensures the consistency of fiber quality under long-term continuous production.

[0045] Example 3: Please refer to Figures 1-8. Based on Examples 1 and 2, the present invention provides a technical solution: an auxiliary mechanism 4 is fixedly connected to the top of the threaded cover 303. The auxiliary mechanism 4 includes a fixing block 401, and the bottom of the fixing block 401 is fixedly connected to the top of the threaded cover 303.

[0046] The top of the fixed block 401 is fixedly connected to the connecting seat 402, and the inner wall of the connecting seat 402 is slidably connected to the lifting sliding block 403. The outer wall of the lifting sliding block 403 is provided with a scale groove 404.

[0047] A second spring 405 is fixedly connected to the bottom of the scale groove 404, and one end of the second spring 405 is fixedly connected to the bottom of the inner wall of the connecting seat 402.

[0048] Furthermore, when the winding bar 2 rotates, it drives the fixed block 401 to rotate. The sliding plate 406, which is slidably connected to the inner wall of the fixed block 401, is thrown out by the centrifugal force, thereby drawing out the air inside the fixed block 401 from the connecting seat 402 and replenishing it. As a result, the lifting sliding block 403 in the connecting seat 402 is drawn down by the negative pressure. The downward movement of the lifting sliding block 403 presses the second spring 405, causing it to deform. This causes the lifting sliding block 403 to continuously increase its descent height as the rotation speed increases. Moreover, through the positional relationship between the scale groove 404 on the outer wall of the lifting sliding block 403 and the connecting seat 402, the operator can intuitively observe the degree of descent of the lifting sliding block 403, thereby judging the current rotation speed and realizing real-time monitoring and adjustment of the unwinding tension. This ensures that the fiber tension is always within the ideal range during the production process, improving spinning precision and product consistency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
