Description

Method for producing eco-friendly salmon leather using salmon skin and salmon skin produced by this method

The present invention is to produce a leather using a non-chrome tanning agent so that the projections of the unique scale pocket pattern on the surface of the salmon skin to the natural effect (Natural effect), so that it can be produced eco-friendly salmon leather with excellent texture and texture It relates to a method for producing environmentally friendly salmon leather using a salmon skin, characterized in that one and a salmon leather produced by this method.

Currently, the general natural leather is mainly produced by utilizing the epidermis of mammals such as cattle, horses, pigs, sheep, goats, or birds such as ostrich or reptiles such as crocodiles, lizards, snakes, and the like.

The general manufacturing method of the leather is classified into four processes: preparation, oiliness, dyeing / branching and finishing. The oily process is a process to make stable fiber tissue by reacting tanning agent such as collagen protein and chromium, and the dyeing process gives various colors according to the merchandise and consumer's desire of leather products. It is a process that gives flexibility to the leather, and finally the finishing coating process.

At this time, there are many types of tanning agents used in tanning in the oil-based process, but most leather manufacturing companies take up tanning with chromium salts, and in the case of chrome tanned leather, heat resistance and long-term storage are increased. It is possible to have excellent dyeing and flexibility, and maintain the protein structure of the protein by chromium after the oil (emulsion) process, it has the advantage to maximize the properties and properties of the leather.

However, despite these advantages, the need for research on tanning methods that reduce the use of chromium or do not use chromium at all is due to the harmfulness of chromium. Most of the chromium used in the tanning process is trivalent or hexavalent chromium. The hexavalent chromium is highly toxic and harmful to the human body such as skin rash or mucous membrane destruction, and only certain conditions (temperature, time, pH, and basicization) When provided, trivalent chromium is easily oxidized to toxic hexavalent chromium. In addition, there is a concern of environmental problems due to the chromium-containing waste liquid, there was a problem that must be recovered and reused or significantly reduced the existing consumption.

As such, leather products with a lot of human contact are mainly made of toxic chemicals, so there is a high possibility of causing allergic skin effects such as atopis and adverse effects on various human health.In addition, it is impossible to reuse resources when disposing of these leather products. In particular, in the case of children or the elderly who have weak skin, long-term patients and persons with disabilities, they have a very sensitive reaction to the external environment or their own belongings or have serious rejection of human toxicity. As an environmentally friendly research method, it has been recognized as an intensive area of concern, and has replaced the conventional chromium-based tanning process to enhance the functionality of leather products among major household products and to make more value-added products for health and the environment. By Vik It was applied to a process (Non-chrome tanning process).

On the other hand, as a raw material of the natural leather, the skin of various fish such as eel, stingray, shark, etc., in addition to the skin of mammal animals, birds, and reptiles, which have been described above, are also used. In addition, since the texture, pattern, and use of natural leather are very different depending on what kind of leather they are made of, it is still necessary to research new materials to satisfy various consumer's preferences.

Therefore, when looking at the contents of the patent application using the skin of such fish, the skin of the fish in skim, washing, degreasing, preliminary emulsion, pickling in Korean Unexamined Patent Publication No. 1987-0003208 (published on April 15, 1987) Leather manufacturing method characterized by pickling, tanning, re-emulsifying and, if necessary, oiling, dyeing, and mechanically processing the epidermis in a known manner, and in Korean Patent Publication No. 10-0788585 No. (December 26, 2007), immersed in a mixture consisting of manganese (Mn) compound containing vitamin C and a ketone chidide, a biochemical of anionic traits, dried in the shade and then extracted with herbal extracts on the surface of the skin. There is known a method of manufacturing a fish fabric, and a fabric manufactured by the fish skin fabric, characterized in that it removes fishy smell by applying and drying, and gives tension to the skin. No. 10-0593412 (June 28, 2006) discloses a leather fabric using tuna skin as a raw material of the leather fabric and a method of manufacturing the same.

However, unlike ordinary land animals, such fish skin has a very weak tissue in the raw skin state and requires careful attention during the tanning process. Scale pockets that have scales and envelop these scales have unique patterns, and despite the high value-adding of leathers, scale pockets are mostly caused by physical and chemical processes during the tanning process. Leather is manufactured in a state of being removed, and the situation is sold at a low price because it does not properly utilize the characteristics of fish skin.

In particular, the development of salmon leather to utilize the scale pocket of salmon using salmon skin is still insufficient, and is very light and dry, easy to dye, easy to tear, and soft to utilize salmon leather. Need research

Therefore, the present invention for solving the above problems is treated in the paddle so that the destruction of the scale pocket (Scale pocket) occurs during the soaking and lime treatment to exhibit a natural effect peculiar to the salmon fish, lime treatment By using lime alone and drying in a vacuum dryer, the scales of the surface of the salmon skin are evenly compressed to produce salmon leather with the projections of the unique scale pocket of the salmon skin. An object of the present invention is to provide an eco-friendly method for producing salmon leather using salmon skin.

In addition, the present invention is environmentally friendly by not generating environmental pollutants using non-chromium tanning agent, and uses a silicone-based compound together with a non-chromium tanning agent during retanning to improve the flexibility of salmon leather, and leather. By using a vacuum dryer to minimize the drying shrinkage of the method, the manufacturing method of eco-friendly salmon leather using salmon skin, characterized in that the eco-friendly method of excellent elasticity and texture of Salmon leather (Salmon leather) Providing is another task.

In addition, the present invention by manufacturing the salmon leather by the above method, by producing the leather utilizing the unique pattern of the unique scale of the salmon (Scale) and the scale pocket (Scale pocket) surrounding the scale to improve the merchandise value Another object is to provide a salmon leather characterized in that.

Therefore, the present invention for achieving the above object in the manufacturing method of the salmon leather to be produced through the preparation process, the oiliness process, dyeing / eggplant process and finishing process,

There is an advantage that can be used in various fields such as sports gloves and wallets, handbags, clothing.

In addition, another object of the present invention is not only environmentally friendly by using a non-chrome tanning agent to generate environmental pollutants, but also a silicon compound with a non-chrome tannin agent during the retanning process to enhance the flexibility of salmon skin In order to improve the elasticity and texture of salmon leather by using a vacuum dryer to minimize the drying shrinkage rate of the leather, the merchandise value can be increased.

In order to achieve the above effects, the present invention relates to a method for producing an environmentally friendly salmon leather utilizing salmon skin and a salmon leather produced by the method, which will be described below in detail with reference to preferred embodiments of the present invention. It should be noted that in the following description, only parts necessary for understanding the present invention are described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

Looking at the manufacturing process of the conventional leather, by using the skin, such as mammals, reptiles to prepare the leather through the preparation process, oily process, dyeing / eggplant process and finishing process. And the preparation process is subdivided into soaking, lime (liming), deliming, beating (Bating) process, the oil process is subdivided into pickling, tanning, neutralization, dyeing process The leather is manufactured through a complex process such as silver dyeing, fatliquoring and retanning, and the finishing process is subdivided into the drying process.

Hereinafter, described in detail the manufacturing method of the salmon leather according to the present invention.

The present invention provides a method for producing salmon leather, which is prepared through a preparation process, an oiliness process, a dyeing / branching process, and a finishing process.

Lime treatment in the preparatory process is used to treat salmon skin using only lime (Ca (OH) ₂ ),

Tanning treatment in the planetary process is processed using a non-chromium tanning agent,

In the dyeing / branching process, the retanning treatment is performed using a silicon compound together with a non-chrome tanning agent.

And the drying (drying) in the finishing process relates to a method for producing an environmentally friendly salmon leather using salmon skin, characterized in that is manufactured through a drying process using a vacuum dryer (vacuum dryer).

The manufacturing method of environmentally friendly leather using salmon skin according to the present invention is also produced by the conventional method of manufacturing leather, the unique scale of the salmon (Scale) and the scale pocket (Scale pocket) surrounding the scales The manufacturing method to make the most of the unique pattern is a feature of the present invention.

And here, the manufacturing process of salmon leather may further include a variety of conventional treatment methods in addition to the treatment method mentioned above, depending on the use and need of the leather.

In the present invention, the preparation process is the same process as the conventional manufacturing process of natural leather, removes the soluble proteins in the salt and raw material sprayed to prevent corruption such as dirt and blood attached to the skin, absorbs moisture and softens Soaking treatment to reduce the raw skin to the state of the skin, and immerse the skin in a solution containing strong alkaline chemicals such as calcium hydroxide to remove the hair (scales) of the skin, water-soluble proteins between the epidermis and the fiber, lipids, etc. Swelling lime treatment, neutralization and removal of lime penetrated into the skin using demineralizing agents such as eye and salt eye, and deliming treatment to return the swollen state to its original state and unnecessary protein layer ( Hydrolyze collagen) with proteolytic enzymes to relax the fibrous tissue to improve flexibility and stretch, and to obtain leather with beautiful grain It is a process of performing a batting treatment.

Lime (liming) in the present invention is to remove the scales of the salmon skin, the process of processing to be able to preserve the pattern of the scale bag as the original pattern is treated using only lime (Ca (OH) ₂ ). .

Conventional lime processing uses a mixture of lime (Ca (OH) ₂ ) with sodium sulfide (Na ₂ S) and sodium hydrosulfide (NaSH).

In the present invention, lime (Ca (OH) ₂ ) is preferably treated for 1 to 48 hours using 1 to 10 parts by weight based on 100 parts by weight of fish.

From above If the amount of lime used is less than 1 part by weight, or the treatment time is less than 1 hour, there is a concern that the scales of the fish may not be removed properly, and if the amount of use exceeds 10 parts by weight or the processing time exceeds 48 hours, the productivity may be deteriorated or excessive. Alkali swelling results in the destruction of salmon skin tissue.

In the case of using the conventional lime soda sulphide (Na ₂ S) or sodium sulphide (NaSH) is used to remove the scales and scale pockets of the skin it is difficult to protect the patterns unique to the scale bag as it is.

In addition, in order to minimize the physical damage (Damage), and to preserve the scale scale pattern of the skin as it is, the water droplet and lime processing is preferably performed at a temperature of 18 ~ 20 ℃ in the paddle (paddle). If the treatment temperature is less than 18 ℃, the opening of the skin tissue is not made, the problem of poor drug penetration occurs, and if the temperature exceeds 20 ℃, the skin of the salmon is damaged and difficult to manufacture leather.

And the paddle is made of the water chuck and lime treatment using 400 to 600 parts by weight of water with respect to 100 parts by weight of fish.

The deliming treatment is preferably performed by rotating in a drum.

And the oil-based process is a pre-treatment condition for tanning pickling treatment to immerse in acid so that the pH is suitable for long-term storage to protect from mold or bacteria for anti-corruption, and the tanning agent to the collagen protein of unstable structure It is a process to perform tanning treatment which converts into mineral leather property and gives heat resistance and flexibility.

In the present invention, the tanning treatment is preferably performed using 1 to 20 parts by weight of the non-chromium tanning agent based on 100 parts by weight of the skin.

When the non-chromium tanning agent is less than 1 part by weight, it does not enhance the filling and density of the leather and does not impart sufficient heat resistance and flexibility to weaken the physical properties and decrease the smoothness of the leather. If it exceeds 20 parts by weight, problems such as weakening of physical properties such as flexibility and tensile strength will occur.

In addition, the dyeing / branching process is a step of matching dyes to convert the collagen protein of eggplant treatment and unstable structure, which gives flexibility and elasticity, to mineral leather, using tanning agent, to provide retinning (heat resistance and flexibility) Retanning) process.

According to the present invention, the eggplant treatment in the dyeing / branching process is carried out for 60 to 480 minutes using 10 to 15 parts by weight of fatliquoring agent and 0.5 to 1.0 parts by weight of formic acid (CH ₃ COOH) based on 100 parts by weight of tanned skin. The drum is rotated and processed.

The eggplant is used as an additive to soften the leather in leather production, increase the fullness and rigidity of the leather, protect the leather from moisture, contamination and external chemical influences, and formic acid has a pH of 3.2 to 4.0 It is used to fix the eggplant in the skin by adjusting it. If the amount of eggplant is less than 10 parts by weight, the leather cannot be softened sufficiently. And, if the amount of formic acid is less than 0.5 parts by weight, there is a lack of flexibility of the leather, if the amount is more than 1.0 parts by weight, there is a problem that the leather is not soft and hard. In addition, if the drum rotation time is less than 60 minutes, the penetration of the branching agent is not smooth, if the drum rotation time exceeds 480 minutes, physical damage of the leather occurs due to excessive rotation.

The branching agents used in the present invention are typically branching agents used in the manufacturing process of natural leather, and there are sulfated branched branch, sulfurous acid branched branch, phosphorylated branched branch, silicone branched branch, sulfonated branched branch, etc. The kind of branching agent used in the invention is not particularly limited, but specifically, one or more kinds of natural oils, synthetic oils (Syntjetic oil, Petroleum oil), and mineral oils (Mineral oil) may be selected and used. The natural fats and oils are generic to oils obtained from nature and include animal oils, vegetable oils, and mineral oils, but are mainly classified into animal oils, vegetable oils, fish oils, and fish oils.

In the present invention, the pH adjusting agent may be used in addition to formic acid, sodium bicarbonate (NaHCO ₃ ), sodium carbonate (Na ₂ CO ₃ ), sodium formate (HCOONa) and naphthalene-based neutral synthetic tanning agent.

Skin treated with eggplant and formic acid is aged at room temperature for 3-5 days.

The retanning treatment is preferably performed for 120 to 240 minutes using 10 to 20 parts by weight of the non-chrome tanning agent and 20 to 30 parts by weight of the silicon compound based on 100 parts by weight of the skin.

When the non-chromium tanning agent and the silicone compound are less than the above-defined range, the softness and filling feeling of the manufactured natural leather is insufficient, resulting in weak physical properties and reduced smoothness of the leather. If you do, the strength is stronger and hardening occurs a problem that the inherent softness of the natural leather is lowered.

In the above, the silicone-based compound is used to prevent excessive shrinkage of the leather by the non-chromium tanning agent and to give flexibility, and when the amount is less than 20 parts by weight, it does not show the effect of preventing the shrinkage of the leather and provides flexibility. If the amount is more than 30 parts by weight, the production cost is increased due to the excess use, the economy is lowered.

The silicon-based compound is preferably Densodrin S (trade name, manufacturer: BASF).

Non-chromium tanning agents used in the tanning and retanning treatment are typically mineral tanning agents such as aluminum, zirconium, titanium, and iron, mimosa, quebracho, and chess nuts. Vegetable tanning agents derived from plants such as Chestnut, Oak, Pine, Mangrove and Hemlock, and acrylics, phenol condensates, urea condensates and sulfones One or more may be selected from synthetic tanning agents such as sulfones, melamine, and protein condensates.

And the deliming treatment to retanning is generally made in a drum, 200 to 300 parts by weight of water with respect to 100 parts by weight of fish, but the amount of water is not particularly limited, can be appropriately adjusted as necessary will be.

In the present invention, the color of the salmon leather manufactured through the above treatment process can be dyed to an appropriate color according to the needs of consumers or the needs of manufacturers during the dyeing process.

On the other hand, in the present invention, in order to manufacture the salmon leather to white tanning (Tanning) and then bleached with permanganate (KMnO ₄ ) and sodium bisulfite (NaHSO ₃ ) and then retanning (white non-chromium) Retanning should be carried out using a silicone compound with the tanning agent.

This bleaching process is carried out to completely remove the pigments indicating the scale pocket pattern, and after dissolving salt (NaCl) in water under the condition of Bomedo (° Be) 6-10, 2 to 4 parts by weight of potassium permanganate (KMnO ₄ ) is added to 100 parts by weight of skin, treated for 10 to 240 minutes, then drained, and salt (NaCl) is added again to conditions of Bomedo (° Be) 6 to 10 After dissolving in water to 100 parts by weight of sodium bisulfite (NaHSO ₃ ) 1 to 20 parts by weight and treated for 10 to 240 minutes, it is preferable to go through the steps of drainage and washing.

When the use amount of the permanganate (KMnO ₄ ) and sodium bisulfite (NaHSO ₃ ) is out of the above range or the treatment time is out of the above range, it is not possible to completely remove the pigments indicating the scale pocket pattern of the surface of the salmon skin, and thus clean white It does not have, or the effect of exceeding the range is insignificant.

In the retanning treatment of the skin after bleaching, 1 to 20 parts by weight of the white non-chromium tanning agent and 1 to 30 parts by weight of the silicon compound are mixed and treated for 10 to 240 minutes to produce white salmon leather. It is desirable to.

If the amount of the white non-chromium tanning agent is less than 1 part by weight or the treatment time is less than 10 minutes, the whiteness of the leather is not sufficiently enhanced, the filling effect is insignificant, and the amount is more than 20 parts by weight, or the treatment time. If it exceeds 240 minutes, material cost increases and silver surface damage occurs during non-chrome tanning.

The white non-chromium tanning agent is a commercially available product and may be selected from one or more of Tanicor PWPp ^® , Basyntan DLE ^® , and Neutan WSK ^® .

And after the tanning treatment in the present invention further includes a bleaching treatment process using bleaching using potassium permanganate (KMnO ₄ ) and sodium bisulfite (NaHSO ₃ ), using a white non-chromium tanning agent in the retanning treatment as described above Can be whitened.

In the bleaching treatment described above, 100 to 150 parts by weight of water is used based on 100 parts by weight of fish.

Therefore, the present invention is a retanning process using a white non-chromium tanning agent in the planetary process, excellent whiteness and excellent surface effect is completely removed pigment of the scale pocket (Scale pocket) of salmon (Salmon) Salmon leather can be made.

And the present invention vacuum drying the leather matured during the drying process at a pressure of 0.1 ~ 80 psi for 1 to 120 minutes at a temperature condition of 20 ~ 100 ℃ using a vacuum dryer (Vacuum dryer) It is preferable to let.

The drying process is carried out in a vacuum dryer to vacuum press and dry to fix the shape of the salmon leather (soft), and the shape of the salmon leather is constant since the shrinkage rate is low after drying, in particular, the scale pocket is pressed evenly on the surface of the projection Will form. When the drying treatment is out of the above drying conditions, the scale bag may not be sufficiently compressed on the surface of the salmon leather or may be over-compressed so that its unique pattern may be damaged and may not have desired characteristics.

Therefore, by using the paddle (Paddle) in the water droplet and lime treatment of the preparation process according to the present invention, by using the lime alone in the lime treatment, the scales are removed without damaging the scale pockets, vacuum dryer in the finishing process By going through the drying process, the shrinkage after drying is a small form of the produced salmon leather is uniform, especially the scale pocket is pressed evenly on the surface of the leather to form a projection. Furthermore, it is possible to completely remove chromium as a tanning agent and to provide a method for producing a pollution-free salmon leather using a non-chrome tanning agent.

Such salmon leather of the present invention is very excellent in the anti-slip and twist prevention effect by the projection of the scale pocket formed when manufacturing the sports and climbing gloves, such as golf, for example, the golf grip slip or twist It becomes hard to lose and can putt with a sense of stability. And salmon leather of the present invention may be applied to a variety of fields, such as wallets, handbags, clothing, boots as needed.

Hereinafter will be described in detail based on the preferred embodiment of the present invention, the present invention is not limited by the embodiment.

The tanning process of the oily process is performed using 10 parts by weight of zirconium as a non-chromium tanning agent based on 100 parts by weight of fish, and 10 parts by weight of fatliquoring agent and formic acid (CH) based on 100 parts by weight of fish. ₃ COOH) 1.0 parts by weight of the drum (Drum) was rotated for 60 minutes and then aged at room temperature for 3 days. The aged skin was treated with 10 parts by weight of Densodrin S (trade name: BASF) and 20 parts by weight of synthetic syntan as a silicon compound in the retanning process.

In the finishing process, a vacuum dryer was used to dry the vacuum at a pressure of 0.1 psi for 5 minutes at a temperature of 45 ° C. using a vacuum dryer to compress salmon pouches unique to salmon leather. Salmon leather having a patterned projection was prepared.

(Example 2)

To prepare salmon leather in the same manner as in Example 1, in order to produce a salmon leather (flexible) leather in the tanning process, aluminum and zirconium is mixed in a weight ratio of 8: 2 as a non-chrome tanning agent. Using 20 parts by weight of the prepared tanned salmon leather (Salmon leather) was produced a salmon leather having a projection of the pegged scale pockets unique.

(Example 3)

Salmon leather was prepared in the same manner as in Example 1, but was applied for 180 minutes using 20 parts by weight of white syntan (Tanicor PWPp ^® ) instead of zirconium as a non-chrome tanning agent based on 100 parts by weight of the skin during retanning. To prepare a salmon leather having a projection of white compressed scale pocket pattern.

(Example 4)

(Comparative Example 1)

Salmon leather was prepared in the same manner as in Example 1, but was carried out by a general preparation process, an oiliness process, a dyeing / branching process, and a finishing process. Retanning of the eggplant process was performed using only non-chromium tanning agent and no silicon compound. The drying process of the finishing process was performed in an air convection dryer at a temperature of 45 ° C.

2. Measurement of Salmon Leather Properties

Shrinkage evaluation was performed by measuring the size of the salmon leather before and after the drying treatment step of Examples 1 to 4 and Comparative Example 1. The test conditions were dried at a pressure of 0.1 psi for 5 minutes at 45 ° C. for 5 minutes in the vacuum dryers of Examples 1 to 4 and the air convection dryer of Comparative Example 1, and the shrinkage was measured and the results are shown in the following [Table 1]. It was.

The size of the test piece was A4 size, and after drawing a square of 15 cm in width and length, the exact dimensions were measured and measured again after the test.

In addition, after manufacturing golf gloves using the salmon leather of Examples 1 to 4 and Comparative Example 1, each adult male and female were each wearing 20 gloves and prepared a golf putting practice course to putt and then golf. The degree of anti-slip and twist of the grip was measured and the average thereof is shown in Table 1 below.

division Example Comparative example One 2 3 4 One Heat Shrinkage (%) 3.1 2.7 3.2 3.1 7.3 Anti-slip ○ ○ ○ ○ × Torsion ○ ○ ○ ○ ×

-○: Very good without slip or twist.

-△: Some slip or gap occurs.

-×: Both slip and torsion occur.

As can be seen from Examples 1 to 4 by drying in a vacuum dryer in order to minimize the dry shrinkage of the leather, compared to Comparative Example 1 shows a very low heat shrinkage rate, the shape of the salmon leather is not significantly changed, it is fixed As it can be seen, the scales of the salmon fish are pressed onto the surface of the manufactured gloves to form protrusions, which prevents the golf grip from slipping or twisting in the hand when putting, thereby preventing slippage and twisting. The prevention effect is also very good. In particular, Examples 3 and 4 were white salmon leather was excellent in aesthetic sense.

However, Comparative Example 1 shows that the heat shrinkage rate is very high as compared with the Example by drying in a heat dryer, and the scale pockets on the surface of the fish skin are destroyed by performing the water droplet and lime treatment on the drum. By having a smooth surface without forming protrusions, it was found that the effects of anti-slip and torsional prevention were very low as compared with the embodiment as shown above.

As described above, the method for producing eco-friendly salmon leather using salmon skin according to the present invention and the salmon leather produced by the method are described through the above-described preferred embodiments, and the superiority thereof has been confirmed.
