Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of leather, and particularly to a preparation method of a suede simulated texture technical fabric. Background Art
[0002] Leather is an indispensable component in industries such as shoemaking, leather clothing, and leather goods. For example, it also plays an important role in interior decorations such as car seats and car door panels. Leather generally refers to processed animal skins. Due to the preciousness and scarcity of animal skins, people pay attention to them, and the use of artificial leather has become more widespread.
[0003] Artificial leather is processed by laminating materials such as PVC and PU on the basis of knitted fabric, and has the advantages of low cost and durability.
[0004] Due to limitations in manufacturing machinery and processes, the existing artificial leather has a low simulation degree in the suede and aging processes and poor hand feeling. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a preparation method of a suede simulated texture technical fabric. The technical fabric manufactured by this preparation method has a suede and aging process comparable to that of genuine leather and excellent hand feeling.
[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:
[0007] A preparation method of a suede simulated texture technical fabric includes the following steps:
[0008] S1: Uniformly apply water-based ink on a substrate at 200 - 210 °C at a speed of 10 - 20 m / min for printing;
[0009] S2: First wind the printed substrate around a wire roller with 30 - 50 meshes, then add glue, methyl ethyl ketone, and a curing agent to a mixer in a certain proportion and stir. After stirring evenly, a mixture A is formed. At 120 - 140 °C, at a speed of 10 - 20 m / min, uniformly press the mixture A on the printed substrate;
[0010] S3: Composite a special weft-knitted yarn-dyed base fabric on the substrate at 100 - 120 °C at a speed of 15 - 20 m / min;
[0011] S4: Emboss the substrate with the composite special weft-knitted yarn-dyed base fabric at 190 - 210 °C at a speed of 3 - 9 m / min to form a rough embryo of the technical fabric;
[0012] S5: Use a sand base with 400 - 800 meshes to perform suede treatment on the rough embryo of the technical fabric at a speed of 10 - 20 m / min to form a finished product of the technical fabric;
[0013] S6: Wash and dry the finished high-tech fabric product.
[0014] Preferably, the ratio of glue, methyl ethyl ketone and curing agent in S2 is 4:5.7:0.3.
[0015] Preferably, in S5, a four-roll continuous grinding machine is used to make the sueding more delicate.
[0016] Preferably, in S5, dry-wet mixed sueding is also adopted, where the dryness level is 4 and the humidity level is 3.5.
[0017] Preferably, in S6, the high-tech fabric is washed in water at a temperature of 20°C for 5 minutes.
[0018] Preferably, in S6, the high-tech fabric is baked in an oven at a temperature of 90°C for 30 minutes.
[0019] Compared with the prior art, the present application has the following beneficial effects:
[0020] After the printing of the present invention is completed, the substrate is wound around a roller with a certain mesh number. When pressing the glue, the mixture A can be pressed more evenly and finely on the substrate. With such a design, the sueding of the high-tech fabric can be more uniform, and the four-roll continuous grinding machine can make the sueding and antiquing texture of the high-tech fabric more delicate and realistic.
