A natural heating environment-friendly anti-felting material production process and an anti-felting material prepared by the process

Abstract

This invention discloses a natural heating environmentally friendly suede material production process and the suede material prepared therefrom, belonging to the field of nonwoven fabric drying technology. The drying and napping processes in the production process utilize a drying and grinding assembly that perfectly combines the drying and napping processes. The drying and grinding assembly includes a first spin-drying area and a second grinding and drying area. In the first spin-drying area, a single layer of washed nonwoven fabric is wound around the spiral roller shell of a rotating grinding roller assembly. The spiral roller shell is then driven to rotate, thereby centrifugally dewatering the single layer of nonwoven fabric and transferring the moisture from the inside of the nonwoven fabric to the outside, facilitating subsequent napping and re-drying operations on the inside of the nonwoven fabric. The drying and grinding assembly is then moved to the second grinding and drying area, where the drying device and the napping device work together to achieve efficient drying and napping of the fabric.

Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric drying technology, specifically to a natural heating environmentally friendly suede material production process and the suede material prepared therefrom. Background Technology

[0002] Resuede material is obtained by using a grinding device to create a nap on one side of dried nonwoven fabric. It is often used in thermal shoes. Existing suede materials have separate drying and grinding processes, resulting in long forming times and low efficiency. This is especially true for the drying process of nonwoven fabric. Current methods typically involve hot air passing through the nonwoven fabric, squeezing out water with rollers, or drying in a drying oven. For example, Patent Document 1 (CN114705020B) discloses an airflow-based nonwoven fabric production and processing equipment. This equipment dries the nonwoven fabric by a drying component located in the top plate before it is wound by a winding drum. The drying component uses heated air to dry the nonwoven fabric, and the combined action of the component improves the drying effect. Another example is Patent Document 2 (CN116608666B). Interference-resistant yarn drying equipment addresses the problems of low efficiency, long drying time, uneven drying due to large piles of yarn, and insufficient heat utilization during yarn drying. It winds the yarn onto a roll structure that can expand or contract, and incorporates a dispersion structure. This allows the yarn to be dried quickly, effectively, and comprehensively in conjunction with the hot air inside the drying chamber. Finally, the suede grinding method disclosed in Patent Document 3 (CN1858261B) involves pressing the leather tightly against a conveyor belt and then using a frame equipped with abrasive gauze to drive the gauze closer to or away from the vertically arranged leather to achieve abrasive grinding, resulting in suede material. However, this grinding method has low efficiency and does not consider that combining drying and grinding processes can improve production efficiency.

[0003] In summary, existing technologies for preparing suede materials all involve first preparing a nonwoven fabric, then drying the nonwoven fabric using a drying device, and finally grinding the dried nonwoven fabric on one side to obtain the suede material. However, these methods do not combine drying and grinding, resulting in low production efficiency. Furthermore, they lack a composite drying method that combines centrifugal dehydration and airflow dehydration. Therefore, this invention provides a natural heating environmentally friendly suede material production process and the suede material prepared using graphene as a material to enhance the heat insulation properties of the suede material. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a production process for a naturally heating and environmentally friendly suede material, the production process comprising the following steps:

[0005] S1. Non-woven fabric impregnated with water-based polyurethane solution:

[0006] The nonwoven fabric is impregnated in an aqueous polyurethane impregnation solution, which is prepared by uniformly mixing 20-50 parts of water, 50-100 parts of aqueous polyurethane, 1-3 parts of thickener, 5 parts of graphene and 1 part of dispersant.

[0007] S2, Alkali Reduction Treatment:

[0008] The impregnated nonwoven fabric is placed in a sodium hydroxide aqueous solution with a mass fraction of 10-15% for simultaneous coagulation and alkali reduction treatment.

[0009] S3, drying, sanding and napping:

[0010] After the nonwoven fabric undergoes alkali reduction treatment, it is washed to remove residual alkali and dissolve residual "sea" components, forming a fabric to be treated. The fabric to be treated is then dried and napped by a drying and grinding assembly to obtain a napped material. The drying and grinding assembly includes a base assembly 1 and a top cover assembly 2. An adjacent first spin-drying area and a second grinding and drying area are set on the base assembly 1. The second grinding and drying area is formed by the base assembly 1 and the top cover assembly 2. Several rotating spin-drying belts are set in the first spin-drying area, and several drying belts are set in the second grinding and drying area.

[0011] The specific steps for drying, sanding, and napping are as follows:

[0012] S3.1 Spin-dry

[0013] The fabric to be treated is mounted on a rotating grinding roller assembly. The fabric to be treated is wrapped in a single layer on the rotating grinding roller assembly. The rotating grinding roller assembly is rotatably set in the first spin-drying area to form the rotating spin-drying belt assembly in the first state. The rotation of the rotating spin-drying belt assembly drives the moisture inside the fabric to move to the outside of the fabric, so that the inner layer of the fabric to be treated is dried.

[0014] S3.2 Grinding and drying

[0015] The rotating grinding roller assembly, with the inner layer of the fabric to be treated wrapped in dry material, is slid to the second grinding and drying area, allowing the fabric to extend out of the rotating grinding roller assembly. The rotating grinding roller assembly in the second state forms the drying belt assembly. The two ends of the fabric to be treated are fixed to the base assembly. The drying device in the second grinding and drying area is activated to dry the fabric to be treated. The rotating grinding roller assembly slides along the base assembly, allowing the grinding plates inside the rotating grinding roller assembly to extend out and perform grinding operations on the inner layer of the fabric to be treated, forming a pile, thus obtaining the naturally heated environmentally friendly reverse pile material.

[0019] Preferably, both the first and second rotating disk groups include a turntable, a hollow cylinder, and a drive rod drive tube. The hollow cylinder is located on the outside of the turntable and on the inside of the drive rod drive tube. Both the first and second fabric guide rod groups include a drive ring, a first radial telescopic drive rod, a drive rod intermediate joint, and a second axial telescopic drive rod. The drive ring is rotatably disposed on the outside of the hollow cylinder. One end of the first radial telescopic drive rod is disposed on the outside of the drive ring, and the other end of the first radial telescopic drive rod is connected to the drive rod intermediate joint. The other end of the drive rod intermediate joint is connected to the second axial telescopic drive rod, and the end of the second axial telescopic drive rod is connected to the fabric joint assembly.

[0023] Preferably, the first grinding plate group is composed of a plurality of first grinding plates, and the second grinding plate group is composed of a plurality of second grinding plates. Both the first grinding plate and the second grinding plate include a rotating grinding arc plate, a rotating drive rod, a first rotating shaft, and a second rotating shaft. The rotating drive rod is hinged to the side of the rotating grinding arc plate near the first drive rod or the second drive rod. The first rotating shaft and the second rotating shaft are disposed on both sides of the rotating grinding arc plate. The first rotating shaft is inserted into a first rotating recess, and the second rotating shaft is inserted into a second rotating recess. The first drive rod or the second drive rod passes through the rotating drive rod.

[0024] It also includes a suede material, which is prepared by the environmentally friendly suede material production process.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] 1. The present invention discloses a natural heating environmentally friendly suede material production process. When drying and napping nonwoven fabric after water washing, a drying and grinding component is used to perfectly combine the drying and napping processes. The drying and grinding component includes a first spin-drying area and a second grinding and drying area. In the first spin-drying area, the washed nonwoven fabric is wound in a single layer around the spiral roller shell of the rotating grinding roller group. Then, the spiral roller shell is driven to rotate, thereby centrifugally dewatering the single layer of nonwoven fabric and transferring the moisture on the inside of the nonwoven fabric to the outside, which facilitates the subsequent napping and re-drying operations on the inside of the nonwoven fabric. The drying and grinding component is moved to the second grinding and drying area, and then the drying device and the napping device in the second grinding and drying area work together to achieve efficient drying and napping of the fabric.

[0027] 2. When grinding and drying the rotating grinding roller assembly in the second grinding and drying area, the first and second fabric guide rod assemblies are extended so that the fabric to be treated is only wrapped 1 to 3 times around the spiral roller shell. Then, the first and second grinding plate assemblies are driven to extend out of the spiral roller shell, and the sliding drive block is driven to move back and forth along the limit guide groove. This causes the extended first and second grinding plate assemblies to perform a napping operation on the inner side of the fabric to be treated. During the napping operation, the drying device in the second grinding and drying area is activated to dry the fabric to be treated, so that the drying and napping operations are carried out simultaneously.

[0028] 3. To further improve the efficiency of the suede material production process, the drying and grinding assembly also includes a winding area. The winding area, the second grinding and drying area, and the first spin-drying area are connected in sequence. After completing the spin-drying operation, the rotating spin-drying belt can enter the second grinding and drying area, allowing the fabric to be processed on the rotating spin-drying belt to be pulled out. Only 1-3 turns of the fabric to be processed are wrapped around the spiral roller shell. Then, the inner side of the fabric to be processed is napped, and the entire fabric to be processed is dried. After drying, it can reach the winding area again, and then the processed fabric is transferred to the ordinary winding roller. The fabric joint assembly includes a drive rod receiving tube and a fabric receiving clamp. The drive rod receiving tube is connected to the fabric receiving clamp through a hinge joint. The receiving clamp is clamped to the end of the fabric to be processed. The drive rod receiving tube is connected to the end of the second axial telescopic drive rod, so that the spiral fabric can be smoothly stored on the ordinary winding roller.

[0029] 4. Finally, the drying belt assembly includes a spiral roller shell, a first rotating disk assembly, a second rotating disk assembly, a first fabric guide rod assembly, a second fabric guide rod assembly, a first grinding plate assembly, and a second grinding plate assembly. The first and second rotating disk assemblies are rotatably mounted on the sliding drive block. When the fabric is pulled out, the first and second fabric guide rod assemblies extend. Both the first and second fabric guide rod assemblies include a drive rod intermediate joint. The drive rod intermediate joint includes a third receiving end that can be engaged into the first or second guide rail and locked, thereby ensuring that both ends of the fabric to be processed can be fixed to points F and G. When napping the inner end of the fabric, the first grinding plate assembly is located at the upper edge of the spiral guide channel, and the second grinding plate assembly is located at the lower edge of the spiral guide channel, thereby napping the entire fabric.

[0044] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] Example 1

[0046] A production process for a naturally heated, environmentally friendly suede material, comprising the following steps:

[0047] S1. Non-woven fabric impregnated with water-based polyurethane solution:

[0048] The nonwoven fabric is impregnated in an aqueous polyurethane impregnation solution, which is prepared by uniformly mixing 20-50 parts of water, 50-100 parts of aqueous polyurethane, 1-3 parts of thickener, 5 parts of graphene and 1 part of dispersant.

[0049] S2, Alkali Reduction Treatment:

[0050] The impregnated nonwoven fabric is placed in a sodium hydroxide aqueous solution with a mass fraction of 10-15% for simultaneous coagulation and alkali reduction treatment. The coagulation and reduction bath temperature is 90-100℃ and the time is 30-60min.

[0051] S3, drying, sanding and napping:

[0052] After the nonwoven fabric undergoes alkali reduction treatment, it is washed to remove residual alkali and dissolve residual "sea" components, forming fabric 4 to be treated. Fabric 4 is then dried, sanded, and napped by the drying and grinding assembly 1 to obtain a napped material. The drying and grinding assembly 1 includes a base assembly 6 and a top cover assembly 7. An adjacent first spin-drying area 2 and a second grinding and drying area 3 are set on the base assembly 6.

The rotating grinding roller group 5 is rotatably set in the first spin-drying area 2. The rotating grinding roller group in the first state forms the rotating spin-drying belt group 62. The rotation of the rotating spin-drying belt group 62 drives the moisture inside the fabric 4 to move to the outside of the fabric 4 to be treated, so that the inner layer of the fabric 4 to be treated is dried.

[0056] S3.2 Grinding and drying

[0057] The rotating grinding roller assembly 5, which wraps the inner layer of the dried fabric to be treated, is slid to the second grinding and drying area 3, so that the fabric to be treated 4 on the rotating grinding roller assembly 5 extends out of the rotating grinding roller assembly 5.

[0078] IV. Rolling up the fabric

[0079] The two ends of the fabric 4 to be treated on the drying belt group 63 in the second grinding and drying area 3 are retracted, so that the fabric 4 to be treated is completely wrapped around the spiral roller shell 8. The side opening and closing plate group 49 between the winding area 56 and the second grinding and drying area 3 is opened, and the drying belt group 63 is moved to the winding area 56 to form the winding belt group 64. The fabric 4 to be treated on the winding belt group 64 is wound up by the winding roller.

[0080] Preferably, the step of retracting both ends of the fabric 4 to be treated on the drying belt group 63 within the second grinding and drying zone 3 specifically involves: as follows Figure 7 As shown in (b), the rotating grinding roller assembly 5 is slid to the middle of the fabric 4 to be processed, and then the rotating grinding roller assembly 5 is rotated relative to the sliding drive block 68, so that both ends of the fabric 4 to be processed retract simultaneously and are wrapped around the spiral roller shell 8.

[0081] Preferably, before both ends of the fabric 4 to be processed are simultaneously retracted, the first rotating disk group 11 and the second rotating disk group 12 are rotated relative to the spiral roller housing 8, so that the first grinding plate group 15 and the second grinding plate group 16 are retracted into the spiral roller housing 8 through the first grinding through hole group 10 and the second grinding through hole group 19, respectively, so that they can be easily retracted.

[0082] Example 3

[0083] like Figure 12 As shown, in order to facilitate the feeding of the fabric 4 to be processed from the spiral roller housing 8 with the spiral guide channel 9 onto the ordinary take-up roller, the fabric joint assembly 24 includes a drive rod receiving tube 65 and a fabric receiving clamp 66.

[0084] The axis of the drive rod receiving tube 65 and the axis of the fabric receiving clamp 66 intersect at point K, and the angle between the axis of the drive rod receiving tube 65 and the axis of the fabric receiving clamp 66 is denoted as α. Preferably, 0° < α ≤ 10°.

[0085] Example 4

[0086] It also includes a suede material, which is prepared by the above-mentioned environmentally friendly suede material production process.

[0087] To facilitate a clear understanding of the working principle of the drying and grinding assembly of this application by those skilled in the art, the following description is provided in conjunction with Embodiment 1: The fabric 4 to be treated, after a water washing process, is wound around the spiral guide channel 9 of the spiral roller shell 8 of the rotating grinding roller assembly 5. The fabric 4 is wound in a single layer without overlap around the spiral roller shell 8. Both sides of the fabric 4 are fixed to the spiral roller shell 8 by the first fabric guide rod assembly 17 and the second fabric guide rod assembly 18, respectively. A sliding drive block 68 is inserted through both ends of the rotating grinding roller assembly 5. Then, the sliding drive block 68 is slid into the limiting guide groove 45 of the base assembly 6, driving the sliding drive block 68 to move along the limiting guide groove 45 to the first spin-drying area 2. Then, the drive component (such as a rotary motor) in the drive hole 70 drives... The hollow cylinder 35 of the rotating grinding roller group 5 rotates relative to the slider body 69 at a certain speed for a certain period of time, so that the moisture located on the inner side of the fabric 4 to be treated can be quickly moved outward, thereby enabling the subsequent napping operation on the inner side of the fabric 4 to be treated. Preferably, the specific rotation time can be controlled by adjusting the rotation speed of the hollow cylinder 35 relative to the slider body 69. If a shorter time is desired, the rotation speed can be increased. After the tumbling is completed, the rotation angle of the hollow cylinder 35 relative to the slider body 69 is adjusted so that the telescopic guide rod at the third receiving end 61 of the drive rod intermediate joint 22 of the first fabric guide rod group 17 and the second fabric guide rod group 18 extends out and abuts against the groove of the first guide rail 46 or the second guide rail 47. Then, the side opening and closing plate assembly 49 on the left side of the drive top cover assembly 2 7 opens, making the first spin-drying area 2 and the second grinding and drying area 3 connected. Then, the slider drive block 68 continues to slide within the limiting guide groove 45, sliding into the second grinding and drying area 3. Then, the side opening and closing plate assembly 49 closes, moving the rotating grinding roller assembly 5 to the middle area of ​​the second grinding and drying area 3. Then, the slider drive block 68 is in a free-rotating state relative to both the first rotating disk assembly 11 and the second rotating disk assembly 12. Then, the first fabric guide rod is driven. Group 17 and the second fabric guide rod group 18 operate synchronously, causing the first radial telescopic drive rod 21 of the first fabric guide rod group 17 and the second fabric guide rod group 18 to extend, and the second axial telescopic drive rod 23 to extend synchronously to adapt to the positions of the two ends of the fabric 4 to be processed. After the fabric 4 to be processed is pulled out into place, the telescopic guide rod continues to extend and locks into the fixing hole, thereby fixing the F and G points at both ends of the fabric 4 to be processed, so that only 1 to 3 turns of the fabric 4 to be processed are wrapped around the spiral roller shell 8.Then, the first rotating disk assembly 11 is rotated at a certain angle relative to the spiral roller housing 8, so that the first drive rod 13 can drive the first grinding plate assembly 15 to extend out of the first grinding through hole assembly 10 of the spiral roller housing 8, and the second rotating disk assembly 12 is rotated at a certain angle relative to the spiral roller housing 8, so that the second drive rod 14 can drive the second grinding plate assembly 16 to extend out of the second grinding through hole assembly 19 of the spiral roller housing 8. Then, the first rotating disk assembly 11 and the second rotating disk assembly 12 are locked relative to the sliding drive block 68. Then, the sliding drive block 68 is driven to slide back and forth along the limiting guide groove 45, as shown. Figure 7 As shown, the driving sliding block 68 moves back and forth between points F and G along the limiting guide groove 45, so that the first grinding plate group 15 and the second grinding plate group 16 grind the inner side of the fabric to be treated 4 that has been dried, and perform a napping operation; at the same time, multiple air jet pipes in the drying device in the second grinding and drying area 3 can spray gas with adjustable temperature, so as to dry the surface of the fabric to be treated 4, and dry it while grinding the fabric to be treated 4, so that the napping and drying operations are carried out at the same time.

[0088] To further improve the efficiency of drying and napping, as shown in Example 2, a winding area 56 is also included on one side of the second grinding and drying area 3. After the rotating spin-drying belt group 62 located in the first spin-drying area 2 enters the drying belt group 63 in the second grinding and drying area 3, in order to ensure the continuity of the process, the rotating grinding roller group 5 with the fabric to be treated 4 wound around it is placed in the first spin-drying area 2. After the drying belt group 63 completes the drying and napping operation, it can enter the winding area 56 to form a winding belt group 64, thereby winding the fabric to be treated 4 onto a regular winding roller. This can form an uninterrupted operation of the rotating grinding roller group 5, improving the efficiency of drying and napping.

[0089] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
