The present invention relates to a method for dyeing synthetic polyamide knotless fishing nets. More specifically, the present invention relates to a method for dyeing knotless fishing nets made of synthetic polyamide that improves level dyeing, prevents flickering, and improves durability and light resistance. In recent years, most fishing nets have been knitted from synthetic polyamide fibers, and knotless nets have come to be used more often than knotted nets. Knotless nets have become widely used because they require less material than knotted nets, are less bulky, and are more durable; however, in terms of dyeability, they are unevenly dyed easy to become,
It also has the disadvantage that it requires long dyeing to eliminate uneven dyeing. At present, synthetic polyamide knotless fishing nets can be produced using direct dyes, acid dyes, etc., using open or pressure-type Obermeyer dyeing machines in combination with leveling dyeing auxiliaries to streamline the process to low bath ratios, e.g. around 1:10. dye,
Uniformly dyed products are obtained using dyes such as disperse dyes. However, synthetic polyamide knotless mesh does not yield a level-dyed product using conventional dyeing methods that are advantageous for knotted mesh, and flickers are noticeable, especially when the mesh is stretched in the lengthwise direction. These drawbacks become more pronounced as metal complex dyes are used as dyes, the bath ratio is lowered, and leveling agents are used more frequently in order to impart fish oil resistance and light resistance to dyed fishing nets. Therefore, in order to improve these drawbacks, the large bath ratio low temperature method,
At present, a large amount of leveling agent is used in the pressurization method, etc., and in addition, a disadvantageous dyeing method is carried out over a long period of time, but it has not been possible to obtain sufficiently satisfactory results. Furthermore, when direct dyes, disperse dyes, etc. are used, dyed fishing nets with relatively good level dyeing properties can be obtained, but the results are unsatisfactory in terms of fish oil resistance and light resistance. The present inventors have arrived at the present invention as a result of intensive research in view of the technical circumstances. That is, the object of the present invention is to provide a novel dyeing method for synthetic polyamide knotless fishing nets that is advantageous in terms of workability and economy.
Another purpose is to provide a synthetic polyamide knotless fishing net that has improved level dyeing, flicker prevention, light resistance, and oil resistance.The composition of the synthetic polyamide knotless fishing net is to add a metal complex dye and dimethyl sulfoxide to the synthetic polyamide knotless fishing net. It consists of applying a dye solution containing the dye to a pick-up ratio of 20 to 40%, and then steaming it for continuous dyeing. The synthetic polyamide knotless fishing net used in the present invention is made by twisting raw threads to form a net thread, and then combining each child of two adjacent mesh threads necessary to form a mesh. Well then,
Examples include a through type, a staggered type, a tortoiseshell type, etc., and the thickness of the net yarn, the number of twists, the mesh, the width and length of the net, etc. are not particularly limited. The dye solution used in the present invention is an aqueous solution containing a metal complex dye and dimethyl sulfoxide (hereinafter abbreviated as DMSO).
Auxiliary agents used in the dyeing of synthetic polyamide knotless fishing nets, such as leveling agents, solubilizing agents, etc., may also be added to the extent that they do not impede the purpose of the present invention. Metal complex dyes are soluble azo dyes in which dye molecules and metal ions such as chromium, cobalt, nickel, and copper are combined in the form of complex salts. o, which has the ability to form complex salts as a structure.
Preferred are 2:1 type complex salt dyes that have any of o'-dihydroxyazo, o-hydroxy-o'-aminoazo, and o-hydroxy-o'-carboxyazo structures and can be dyed in a weakly acidic to neutral bath. .
Specific examples include Neolan dye, Platin Fast dye, Irgalan dye, Lanyl dye, Kayakalan dye, and the like. Metal complex dyes can be dissolved in water using conventional methods, but
The amount and concentration of the liquid are not particularly limited. It is sufficient to have a liquid volume and concentration that is advantageous for continuous dyeing.
A concentration of ~100g/ is preferred. DMSO is colorless;
It is almost odorless, nontoxic, and noncorrosive, so it can be used safely and can be added to an aqueous metal complex dye solution in any proportion to form a homogeneous solution. The amount of DMSO that best exhibits the effects of the present invention is 100 to 300% by weight based on the metal complex dye, and preferably 20 to 50 g/based on the amount of water. Particular attention should be paid to the fact that a concentration of 100g/concentration or higher in water is not only unnecessary, but may also have an undesirable effect on the after-treatment of fishing nets. The dyeing method of the present invention will be explained below. An undyed synthetic polyamide knotless fishing net is fed out from the rod, introduced into a dye solution tank, allowed to pass through the dye solution tank, and picked up with a mangle to squeeze out excess dye solution. The dye solution application rate is determined by the dye solution concentration and dyeing concentration of the dyed object, and the pick-up rate is 20 to 40%, preferably 25 to 40%. If the amount is too high, not only will a large amount of heat be required during steaming, but also condensed water from the excess liquid will flow on the surface of the fabric, impairing level dyeing. The flicker referred to in the present invention is a phenomenon in which a difference in shade is observed locally when the dyed net is stretched, and is thought to be caused by uneven dyeing. The screen coated with the dye liquid is then led to a steaming chamber, where the temperature is rapidly raised by atmospheric saturated steam, and the screen is allowed to remain there for a period of time necessary for fixation of the dye. After the dye has been fixed, the undyed dye is removed by washing continuously or in the usual way with water, and if necessary, a resin finishing agent, softener, antistatic agent, etc. are applied, and then the net is taken to a drying room. dry. According to the dyeing method of the present invention having such a configuration, since metal complex dyes can be used in synthetic polyamide knotless fishing nets at a desired bath ratio, dyed fishing nets with high fastness and excellent level dyeing properties can be economically obtained. Moreover, the conventional flickering was completely eliminated. The present invention will be explained in detail below with reference to Examples, but the present invention is not limited thereto. Examples 1 to 4 Preparation of padding bath Dye in the amount shown in Table 1 (parts by weight, the same applies hereinafter) and
Mix DMSO thoroughly and add about 500 parts of hot water to dissolve. Add water to make a total volume of 1000 parts and add 0.5 part of acetic acid. It is preferable to add acetic acid just before starting dyeing. Dyeing The temporarily warped nylon knotless fishing net was continuously padded in the previously prepared padding bath, squeezed at the pick-up ratio shown in Table 1, and then introduced into an atmospheric steamer and steamed for 10 minutes. The fishing net was then lightly washed with water and dried. Table 1 shows the results of the color tone, level dyeing, flickering, and sardine oil durability tests of the fishing net. Comparative Example 1 A nylon knotless fishing net was treated with Lanyl under the same conditions as in Example 1 without using DMSO.
Table 1 shows the results of continuous dyeing with Brown 3BO (2:1 type metal complex dye manufactured by Sumitomo Chemical Co., Ltd.). Comparative Example 2 Table 1 shows the results of continuous staining of a nylon knotless fishing net with Lanyl Brown 3BO under the same conditions as in Example 1 except that benzyl alcohol was used instead of DMSO. From the results in Table 1, it can be seen that according to the method of the present invention, nylon knotless fishing nets were uniformly dyed in a beautiful deep color, no flickering was observed, and the method was excellent in durability tests. Comparative Examples 3 to 4 20 parts by weight of Lanyl Brown 3BO and 40 parts by weight of DMSO were dissolved in hot water, and nylon knotless fishing nets were dyed in dye baths with bath ratios of 1:10 and 1:40, respectively, using an Obermeyer in a conventional manner. It was stained. As a result of the dyeing, the level dyeing was good with some slight staining, but the flickering when the fishing net was pulled was not eliminated, and the internal dyeing of the nodules was poor, and the durability with sardine oil was slightly inferior. Comparative Example 5 Using Sumikaron Brown S-5RL (disperse dye manufactured by Sumitomo Chemical Co., Ltd.), a nylon knotless fishing net was dyed according to a conventional method using a high-temperature dyeing method by dipping under the following dye bath conditions. Dye Bath dye 3.0% (owf) Sumipon TF 1g/PH 5 Bath ratio 1:30 As a result of dyeing, the dyed net showed good level dyeing properties,
It showed unsatisfactory results in light fastness and sardine oil durability.
