Description

Process for synthetic leather having double-faced coating layers mixed with perfume and ceramic}

The present invention relates to a synthetic leather and a manufacturing method of the fragrance and ceramic mixed face coating layer,

More specifically, it is an artificial leather, while maintaining the softness and breathability like natural leather, while being durable, it can produce a lot. Also, the coating layer and fiber cloth mixed with bio ceramic powder and fragrance that emit far infrared rays to polyurethane resin Through the artificial artificial pores formed between the surface layer is intended to facilitate the metabolism by fragrance and ceramics.

In general, a conventional artificial leather layer is formed by knife coating a water-soluble polyurethane resin on one surface of a nonwoven fabric or a textile fabric that is a bottom part of artificial leather, and then a polyurethane resin is coated on a release paper on which a leather pattern is formed. After making the transfer sheet and coating it on the primary fiber cloth and bonding it by transfer method, it is immersed in the coagulation room to coagulate and wash the polyurethane resin, then remove the release paper paper and dry to express the leather pattern film on the surface. The fiber cloth and the polyurethane resin are combined to create an artificial leather in which the fiber layer is integrally formed.

As a problem of the artificial leather produced using the release paper as described above,

First, it is immersed and washed in the coagulation room by bonding three types of release paper, polyurethane resin and fiber cloth. In this process, gas and solvent do not escape to the release paper side, but only the fiber cloth. There is a possibility that the product is deteriorated after the finished product is not washed well and the polyurethane resin is quickly aging phenomenon.

Second, since release paper is a consumable, production costs will rise.

Third, when the solidification and washing and dehydration, the solvent is not completely escaped, the artificial leather is not soft, and if used for a long time, there is a problem that the fiber cloth and the polyurethane resin is separated and wears quickly.

In the present invention, in order to solve the above-mentioned problems, when the fiber cloth is coated, the left and right widths are reduced or the upper and lower lengths are not solved. Thus, the polyurethane resin is applied onto the paper using a release paper. It uses a method of bonding and transferring the coated fiber cloth,

Or there is also a method of coating the knife through the roller, which also causes a problem that the left, right, top, bottom of the fabric cloth is reduced or longer, so the thickness is not constant when coating the knife in the present invention, the tension adjustment device is well adjusted in the coating fabric After the left, right width and the upper and lower lengths to be unchanged, and then quantitatively coated on both sides with the first reverse coating device to wrap the fiber cloth in the middle of the polyurethane resin to solidify, wash, dehydrate, heat dry, By applying a reverse roller coating on one side in the secondary and then heat-drying, the artificial leather is obtained by expressing various leather patterns corresponding to the object of the present invention by press-fitting the leather pattern engraving roller.

Referring to the present invention in detail by process according to the accompanying drawings as follows.

1st process

As shown in FIG. 1, the nonwoven fabric or fiber cloth 1 is immersed in the water tank 2, and then dehydrated in the dehydration roller 3 to mix various perfumes 37 and far-infrared bio ceramics 38. The guide roller (6) and the primary tension adjustment roller (5) can be adjusted well so that the penetration of the roller can be controlled by the banana roller (4) so that there are no fluctuations in the left, right width, up and down length. A coating device consisting of a supply container (9) and a reverse roller (7) (8) performs quantitative coating on both sides to wrap the fiber cloth (1) in the middle of the polyurethane resin layer (33), and then becomes a body of leather. After forming the artificial leather resin layer and solidifying it slowly through the secondary tension adjusting roller 12 and the coagulation chamber 11 containing the low temperature water, the solvent of the hydrophilic water-soluble polyurethane layer melted, and then the washing chamber ( 15) and then from the dehydration roller (18) Suhu while passing through the air drying device 19 and the heat drying chamber 20 Ie, the fine holes by a gas generated from the foaming around so that the polyurethane resin is solidified to pass through the inside of seomyupo (1).

Second process ,

One surface of the polyurethane resin layer 33 of artificial leather having a polyurethane resin layer made of a water-soluble polyurethane resin solution coated on both sides of the fiber cloth 1 as shown in the second process diagram of FIG. After adjusting the thickness of the reverse thickness adjusting roller (26) of the coating machine consisting of reverse rollers (24) and (25) interlocked by the third tension adjusting roller (23), various flavors (37) and far-infrared bio ceramics ( 38) Coating the polyurethane resin mixed with the powder and the water-soluble solvent in the secondary resin supply container (27) at once, and then pass through the heat-drying chamber (29) with the coated fiber cloth on the wire mesh conveyor (28). The artificial leather resin layer 34, which is released while generating a gas while the foaming agent receives heat, forms fine artificial pores 36 and passes through the leather pattern engraving roller 30 and the rubber roller 31 by a press-in method. 35) Various leather patterns on The prefecture.

The artificial leather thus produced is selectively subjected to finishing such as wax, reinforcing agent spray, etc. according to the use thereof.

The artificial leather of the present invention manufactured by the above process is a fiber layer (1), artificial leather double-coated water-soluble polyurethane resin layer (33), artificial leather resin layer (34), surface layer (35) as shown in Figures 3 and 4 , Fine artificial pores 36, various perfumes 37, and ceramics 38.

The artificial leather manufactured as described above can be used semi-permanently due to the aging phenomenon of water-soluble polyurethane resin, which does not cause separation of fiber cloth and resin, and can be used in the polyurethane resin by adding foam, perfume, far-infrared bio ceramic, etc. It produces a unique scent that is different from that of far-infrared bio-ceramic, which promotes blood circulation and prevents aging of the human body, and does not use expensive release paper. It is a soft, durable artificial leather with a polyurethane resin wrapped around the fabric of the fabric.
