Description

Technical Field

[0001] The invention relates to the technical field of synthetic leather, in particular to a production method of natural texture synthetic leather. Background Art

[0002] As we all know, natural texture synthetic leather is a kind of imitation leather, which is mainly achieved by simulating the texture, color and touch of natural leather on the surface of synthetic leather. It is widely used in many fields such as fashion, home furnishing, and automobile to achieve a look and feel similar to natural leather, but usually has better performance in terms of cost, durability and maintenance.

[0003] When existing natural texture synthetic leather is produced, the texture on the synthetic leather is generally achieved through mechanical and physical means such as embossing, kneading and absorbing, which will lead to high maintenance and operation costs of mechanical equipment, and require professional personnel to operate, increasing the complexity and cost of production. Summary of the invention

[0004] 1. Technical issues to be solved

[0008] Step 1: First, prepare various substrates for making synthetic leather, then put the substrates into the designated cleaning equipment, clean the substrates, clean the dust and impurities on the substrates, and then weigh the various substrates on the weighing equipment. By calculating the weight of various substrates, the various substrates can be accurately proportioned;

[0009] Step 2: Pour various substrates with good proportions into a melting device, then start the melting device to melt the substrates, melt the multiple substrates together, and then stir the melted substrates through a stirring component on the melting device to fully mix them;

[0010] Step 3: Add various auxiliary agents to the melted substrate. The auxiliary agents need to be weighed with a weighing device to accurately match the auxiliary agents with the substrate.

[0011] Step 4: Pour the prepared liquid coating into the designated coating equipment for later use;

[0012] Step 5: Prepare the raw materials for making normal fibers, clean the raw materials, and then put them into the wire drawing equipment, which is usually used to melt the polymer and draw it into long and thin fibers;

[0013] Step Six: Prepare an appropriate amount of high-shrinkage fibers. Put the high-shrinkage fibers into a cleaning device, clean them thoroughly, remove the dust and impurities on the surface, and then take them out and put them into a drying device to dry the water stains on the surface of the high-shrinkage fibers.

[0014] Step Seven: Place the normal fibers and high-shrinkage fibers on a designated conveyor belt. Through the conveyor belt, transfer the normal fibers and high-shrinkage fibers to a needle punching machine. The needle punching machine can make the normal fibers and high-shrinkage fibers into fabric.

[0015] Step Eight: Take out the fabricated fabric, and then put it into a cutting device to cut the fabric into appropriate sizes.

[0016] Step Nine: Place the cut fabric on a designated coating device, and then start the coating device. Through the coating device, evenly coat the liquid coating poured into the coating device on the fabric.

[0017] Step Ten: Take out the coated fabric, then add water to a heating device, and then start the heating device to heat the water. When the water reaches the designated temperature, put the fabricated fabric into the water in the heating device.

[0018] Step Eleven: After the fabric enters the hot water, the high-shrinkage fibers in the fabric will shrink when heated, thus forming natural patterns, and then take out the fabric.

[0019] Step Twelve: Place the taken-out fabric in a curing device. The curing device cures the fabric by hot air drying. After the work is completed, take out the fabric.

[0020] Step Thirteen: Place the fabric in a spraying device, and spray a stain-proof agent on the surface of the fabric through the spraying device to make the fabric have the effect of stain resistance.

[0021] Step Fourteen: Place the fabricated fabric on a conveyor belt. The conveyor belt transports it to a detection device for detection. If the detection is qualified, it can be packaged, and if it is unqualified, it will be recycled and reused.

[0022] In order to improve the quality of the finished product, the present invention is improved in that the stirring time in Step Two is not less than fifteen minutes.

[0023] In order to improve the cleaning effect, the present invention is improved in that the cleaning devices in Step One and Step Six adopt ultrasonic cleaning devices.

[0024] In order to improve the quality of the finished product, the present invention is improved in that the auxiliary agent in Step Three includes a plasticizer, a stabilizer, and an antibacterial agent.
