As shown in Table 1 to Table 3, each of the second sodium salt copolymers of the first type and the second type prepared through the above-described second sodium salt copolymer manufacturing step (S200) contains nitrogen and phosphorus components. It does not show the form, and shows that it has excellent metal ion containment and biodegradability.

In addition, in the present invention, the third sodium salt polymer manufacturing step may be further included. The polymerization is performed using acrylic acid as a monomer to prepare a homopolymer, but the reaction initiator is hydrogen peroxide, sodium peroxide, ammonium peroxide, potassium peroxide. Using a group of peroxides selected from benzoic acid peroxide and acetic acid peroxide and proceeding at 40-120 ° C. for 3 hours, NaOH may be added to finally prepare a third sodium salt polymer.

The water-soluble polymer-type surfactant manufacturing step (S300) is to reduce the friction coefficient when used in the pretreatment or dyeing and processing process of the textile industry is generated by the friction between the fiber and the fiber as well as the friction between the fiber and the machine It is a step to prepare a polymeric surfactant that can prevent fiber damage and wrinkles, and to realize a high quality of the fiber products.

To this end, since the fatty acid composition contains ricinoleic acid and dihydroxy stearic acid having hydroxyl groups, anionization is possible, and vegetable oils having a molecular weight that is three times or more larger than commercially available higher alcohols and can exhibit excellent smoothness (vegetable) oil) or vegetable oil derivatives are to be used as a base.

However, the vegetable oil (vegetable oil) or vegetable oil derivative is preferably solubilized because it is not water-soluble when used alone.

That is, the step of preparing a water-soluble polymer-type surfactant (S300) is equipped with a vegetable oil (vegetable oil) or vegetable oil derivatives, ethylene oxide is added in a mole ratio 1: 7 ~ 1: 9 for the solubilization treatment To prepare a surfactant in the form of synthesis.

Here, vegetable oil (vegetable oil) or vegetable oil derivatives are provided, but ethylene oxide is added at a mole ratio of 1: 7 to 1: 9 for the solubilization treatment, and then non-ionized and synthesized with an anionized raw material to form an anionic interface. It can be prepared and used as an active agent.

In this case, the vegetable oil may be one or a mixture of two or more selected from palm oil, palm oil, palm kernel oil, cacao butter having a structure consisting of esters of trihydric alcohols and fatty acids.

The surfactant prepared in this way can exhibit the function of water solubility and excellent salt stability and dispersibility.

Here, when the molar ratio of ethylene oxide is less than 7 moles, there are disadvantages in that salt stability and dispersibility are inferior. Synthesis rate may be lowered.

The manufacturing raw material mixing step (S400) is to form a predetermined amount of the first sodium salt copolymer, the second sodium salt copolymer and a surfactant prepared by the above-described steps to complete the multifunctional metal ion blocker by stirring and mixing Step.

In this case, when the third sodium salt polymer manufacturing step is included, 500 to 150 parts by weight of the third sodium salt polymer may be added based on 100 parts by weight of the first sodium salt copolymer.

The raw material addition step (S500) is a step of adding a raw material to add functionality to the metal ion sequestrant prepared in performing the manufacturing raw material mixing step (S400).

In the step of adding the raw material (S500) based on 100 parts by weight of the first sodium salt copolymer 100 to 150 parts by weight of the second sodium salt copolymer, 10 to 50 parts by weight of the surfactant is mixed and stirred, but here pH adjustment In order to be able to impart pH buffering properties, one may further add one selected from alkanol amine, sodium hydroxide and pottasium hydroxide.

At this time, based on 100 parts by weight of the first sodium salt copolymer, the raw material for imparting pH buffering property may be mixed and mixed at 5 to 25 parts by weight.

Here, when added to less than 5 parts by weight relative to the raw material for imparting pH buffering property, the pH buffer effect is insignificant, and when it exceeds 25 parts by weight, alkali and salt stability may be reduced.

Here, the raw material for imparting pH buffering properties can exhibit the pH buffering effect while maintaining alkali and salt stability when the metal ion sequestrant is used in the dyeing and processing process, and through this, dyeing process such as adsorption process or fixing process. It is possible to effectively prevent the occurrence of uneven salt on the surface of the fiber due to the pH when proceeding.

In addition, in the raw material addition step (S500), based on 100 parts by weight of the first sodium salt copolymer 100 to 150 parts by weight of the second sodium salt copolymer, 10 to 50 parts by weight of the surfactant is mixed and stirred, but antimicrobial here And grapefruit extract or grapefruit seed extract may be further added to impart deodorization.

At this time, based on 100 parts by weight of the first sodium salt copolymer, a raw material for imparting antimicrobial activity and deodorization may be prepared by mixing at 10 to 30 parts by weight.

Here, when added to less than 10 parts by weight relative to the raw material for imparting antimicrobial and deodorant antimicrobial and deodorant effect may be lowered, if exceeding 30 parts by weight can increase the antimicrobial and deodorant but the raw material The fragrance may be too strong and may affect the quality of the chromaticity in the dyeing process.

Here, the raw material addition step (S500) may be carried out in the form of adding each of the raw material for imparting pH bufferability and the raw material for imparting antimicrobial and deodorization, sometimes in the form of adding all of these raw materials You can also carry out.

On the other hand, the first sodium salt copolymer manufacturing step (S100) and the second sodium salt copolymer manufacturing step (S200) made of the above-described process, the surfactant manufacturing step having a water solubility (S300), and the raw material mixing step (S400) The performance was tested by applying the dyeing process of the cotton fiber to the metal ion blocker prepared through the), the results are shown in Table 4.

In this case, in the first sodium salt copolymer manufacturing step (S100), a first sodium salt copolymer was prepared by the above-described example, and in the second sodium salt copolymer manufacturing step (S200), the first type of process was performed. A second sodium salt copolymer was prepared, and in the preparation of the surfactant (S300), a surfactant was prepared in the form of using vegetable oil as palm oil and adding ethylene oxide in a mole ratio of 1: 8 to the preparation material. In the mixing step (S400), 120 parts by weight of the second sodium salt copolymer and 20 parts by weight of the surfactant were added to the stirrer based on 100 parts by weight of the first sodium salt copolymer, and then mixed with stirring to complete the metal ion sequestering agent.
