Description

Technical Field

[0001] The present invention belongs to the technical field of non-woven fabrics, and particularly relates to a highly fluffy non-woven fabric and a production process thereof. Background Art

[0002] The main raw material for producing non-woven fabrics is polypropylene pellets, which are produced by a continuous one-step method of high-temperature melting, spinning, laying, hot pressing and winding. Non-woven fabric is a fabric formed without spinning and weaving. It only arranges textile staple fibers or filaments in a directional or random manner to form a fiber web structure, and then is reinforced by mechanical, thermal bonding or chemical methods. It is not woven by interweaving and knitting yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, when you take out the lining in your clothes, you will find that you can't pull out individual threads. Non-woven fabrics break through the traditional textile principle and have the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple raw material sources.

[0003] The raw materials for producing non-woven fabrics also include polypropylene fiber and polyester fiber. In addition, there are also nylon, viscose fiber, acrylic fiber, polyethylene fiber, polyvinyl chloride fiber, etc. Before producing non-woven fabrics, the raw materials are in granular form, and they are prone to be contaminated with dust and other impurities during transportation, manufacturing and storage. When producing non-woven fabrics with granular raw materials containing impurities, the quality of non-woven fabrics will be reduced. Summary of the Invention

[0004] The purpose of the present invention is to provide a highly fluffy non-woven fabric and a production process thereof for the above-mentioned existing technical problems, achieving the effect of ensuring the quality of non-woven fabrics.

[0005] In view of this, the present invention provides a production process of a highly fluffy non-woven fabric, including the following steps:

[0006] Step S1: First, put the raw material particles into a raw material cleaning machine for cleaning, and then dry them;

[0007] Step S2: Mix the PP raw material, PE raw material and COPP raw material after cleaning and drying in Step S1, melt and extrude, filter, and then converge and spin, cool and draw, and air draft to obtain bicomponent fibers;

[0008] Step S3: Draw and lay the bicomponent fibers in Step S2;

[0009] Step S4: Thermally consolidate the fiber web in Step S3 to obtain a highly fluffy non-woven fabric.

[0010] In this technical solution, by pre-cleaning the raw material particles for making non-woven fabrics in a raw material cleaning machine, dust and other impurities can be removed, ensuring the quality of non-woven fabrics.

[0011] Further, the raw material cleaning machine includes a frame, and the following are provided on the frame:

[0012] A liquid storage tank, in which a cleaning liquid is provided. One end of the liquid storage tank is a feeding end, and the other end is a discharging end. The feeding end is used for feeding raw material particles to be cleaned, and the discharging end is used for discharging the cleaned raw material particles.

[0013] A first stirring assembly, which is used for stirring the raw material particles in the liquid storage tank.

[0014] In this technical solution, since the raw material particles are made of plastic and have a low density, they will float on the cleaning liquid after being poured into the liquid storage tank. The first stirring assembly can turn over the raw material particles floating on the cleaning liquid, facilitating the contact of all surfaces of the raw material particles with the cleaning liquid, and improving the cleaning efficiency and quality.

[0015] Further, the first stirring assembly includes:

[0016] A first stirring rod, which is erected above the frame and rotatably connected to the frame. A plurality of stirring blades are provided on the outer periphery of the first stirring rod.

[0017] A first driving structure, which is connected to the first stirring rod and used to drive the first stirring rod to rotate circumferentially.

[0018] Further, a second stirring assembly is also provided on the frame, and the second stirring assembly is used to lift the raw material particles from the liquid storage tank and wash the raw material particles.

[0019] Further, the second stirring assembly includes:

[0020] A second stirring rod, which is erected above the frame and rotatably connected to the frame. Fixed plates are coaxially fixedly connected to both ends of the second stirring rod respectively. A plurality of stirring plates extend outward from the outer periphery of the second stirring rod, and water filtering holes are arranged on the stirring plates. The aperture of the water filtering holes is smaller than the diameter of the raw material particles.

[0021] A second driving structure, which is connected to the second stirring rod and used to drive the second stirring rod to rotate circumferentially.

[0022] A flushing frame, which spans across the frame. A water storage bucket is provided on the flushing frame. A discharge water pipe is connected to the water storage bucket, and the water pipe is used to flush water onto the stirring plates. A liquid guide pipe and a water pump are provided between the water storage bucket and the liquid storage tank, and are used to pump the cleaning liquid in the liquid storage tank into the water storage bucket.

[0023] In this technical solution, the rotation of the stirring plate following the second stirring rod can turn over the raw material particles floating on the cleaning liquid, facilitating the contact of all sides of the raw material particles with the cleaning liquid. At the same time, the stirring plate can pick up the raw material particles, and the cleaning liquid flows out from the water filtering holes, leaving only the raw material particles on the stirring plate. Then, when the stirring plate rotates close to the water outlet pipe, the water outlet pipe sprays water onto the raw material particles on the stirring plate to wash away the debris on the raw material particles, facilitating the improvement of the cleaning efficiency and quality.

[0024] Further, a moving component and a scrubbing component are also provided on the second stirring assembly. The moving component is used to drive the scrubbing component to slide along the length direction of the stirring plate, and the scrubbing component is used to reciprocally scrub the raw material particles on the stirring plate above the stirring plate.

[0025] Further, the scrubbing component includes:

[0026] A scrubbing frame, which is connected to the moving component, and a receiving groove is formed in the scrubbing frame;

[0027] A scrubbing plate, which is slidably arranged in the receiving groove, and the side of the scrubbing plate facing the stirring plate is made of a brush.

[0028] A scrubbing motor, which is fixedly arranged on the extension block outside the scrubbing frame. The output end of the scrubbing motor is connected with a turntable, an eccentric part of the turntable is rotatably connected with a connecting rod, and the other end of the connecting rod is rotatably connected with the scrubbing plate.

[0029] In this technical solution, when the scrubbing motor is started, it can drive the turntable to rotate, so that the connecting rod drives the scrubbing plate to reciprocally rub the raw material particles on the stirring plate. The scrubbing component can scrub off the stubborn debris on the raw material particles, combined with the impact force of the water sprayed by the water outlet pipe, to improve the cleaning efficiency and quality.

[0030] Further, the moving component includes:

[0031] A guiding plate, which is fixed on the outer periphery of the second stirring rod. A guiding groove matching the guiding plate is formed on the extension block of the scrubbing frame, and the scrubbing frame is slidably arranged on the guiding plate through the guiding groove;

[0032] A transmission lead screw, which is arranged along the length direction of the second stirring rod outside the second stirring rod. The transmission lead screw can rotate circumferentially with the moving driving component. A connecting screw hole is arranged on the extension block of the scrubbing frame, and the transmission lead screw is threadedly connected with the scrubbing frame through the connecting screw hole.

[0033] In this technical solution, the moving driving component drives the transmission lead screw to rotate, so that the whole scrubbing frame moves along the length direction of the second stirring rod to reciprocally rub all the raw material particles on the stirring plate.

[0034] Further, six stirring plates are evenly distributed circumferentially on the upper part of the second stirring assembly, and each stirring plate corresponds to a scrubbing assembly. The moving assemblies of the six scrubbing assemblies jointly drive a moving driving assembly, and the moving driving assembly includes:

[0035] A moving driving motor, which is fixedly arranged on a fixing plate;

[0036] Synchronous pulleys, each transmission lead screw is fixedly sleeved with a synchronous pulley, and the output end of the moving driving motor is connected with a transmission gear. One of the synchronous pulleys rotates synchronously with the transmission gear through a first synchronous belt;

[0037] A second synchronous belt, which is sleeved outside the six synchronous pulleys.

[0038] In this technical solution, when the moving driving motor is started, the transmission gear can be rotated, and the rotation is transmitted to one of the synchronous pulleys through the first synchronous belt, and then all the synchronous pulleys are rotated synchronously through the second synchronous belt, so that all the scrubbing assemblies can move along the length direction of the stirring plate.

[0039] Further, a highly fluffy non-woven fabric prepared by adopting the above production process.

[0040] The beneficial effects of the present invention are:

[0041] 1. By pre-placing the raw material particles for making the non-woven fabric into a raw material cleaning machine for cleaning, dust and other impurities can be removed, ensuring the quality of the non-woven fabric.

[0042] 2. Since the raw material particles are made of plastic material and have a low density, after being poured into the liquid storage tank, they will float on the cleaning liquid. Through the first stirring assembly, the raw material particles floating on the cleaning liquid can be turned over, facilitating the contact of all surfaces of the raw material particles with the cleaning liquid, and improving the cleaning efficiency and quality.

[0043] 3. By the rotation of the stirring plate following the second stirring rod, the raw material particles floating on the cleaning liquid can be turned over, facilitating the contact of all surfaces of the raw material particles with the cleaning liquid. At the same time, the stirring plate can pick up the raw material particles, and the cleaning liquid flows out from the water filtering holes, leaving only the raw material particles on the stirring plate. Then when the stirring plate rotates to be close to the water outlet pipe, the water outlet pipe sprays water towards the raw material particles on the stirring plate, flushing the sundries on the raw material particles, and facilitating the improvement of the cleaning efficiency and quality.

[0044] 4. The scrubbing assembly can scrub the stubborn sundries on the raw material particles, combined with the impact force of the water sprayed out by the water outlet pipe, improving the cleaning efficiency and quality. Brief Description of the Drawings
