Description

Technical Field

[0001] The present invention belongs to the technical field of anti-cross-color scented booster beads, and particularly relates to anti-cross-color scented booster beads and a manufacturing method thereof.

Background Art

[0002] An anti-cross-color sheet forms cationic fibers having a positive charge by undergoing a modification process. Its role is to prevent anionic dyes from adhering to clothes of other colors by binding the anionic dyes falling from clothes with positive and negative charges. Scented booster beads are a product containing essence. By adhering the scented booster beads to clothes, the release of the essence can be realized, and it can be ensured that the clothes release the scent for a long time. The usage method of the scented booster beads is the same as that of the anti-cross-color sheet. When washing clothes, the scented booster beads and the clothes can be put into the washing machine together. Currently, as the types of laundry are increasing, when washing, not only detergents but also products having various functions, such as scented booster beads, fabric softeners, anti-cross-color sheets, etc. need to be further added. As a result, the washing process becomes increasingly complicated. By imparting more functions to the scented booster beads, the convenience of washing can be improved. In the conventional scented booster beads, not only essence but also other anionic components (such as surfactants) are further contained. When a cationic anti-cross-color component is directly added into the scented booster beads, the effects of the cationic anti-cross-color component and the anionic component are significantly reduced because some of the cationic anti-cross-color component and the anionic component are combined.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The objective of the present invention is to improve the functionality of scented booster beads and enhance convenience when washing clothes by providing color-mixing prevention type scented booster beads and a method for manufacturing the same, in order to solve the shortcomings of the conventional technology. [Means for solving the problem]

[0004] To achieve the above objective, the present invention employs the following technical features. In a first example of the present invention, a color-mixing-preventing scented booster bead is provided. The color-mixing-preventing scented booster bead includes a first encapsulation film and a second encapsulation film arranged in an inward-outward direction. Essence microcapsules are encapsulated within the second encapsulation film. A cationic anti-color-mixing agent is encapsulated between the first and second encapsulation films. The manufacturing materials for the first and second encapsulation films are water-soluble materials. The core material of the essence microcapsules contains an essence and an anionic surfactant. The cationic anti-color-mixing agent includes at least one of cationic guar gum and cationic polyacrylamide. The first encapsulation film dissolves in water in 2 to 4 minutes, and the second encapsulation film dissolves in water in 1 to 1.5 minutes.

[0005] In the aforementioned color-mixing-preventing scented booster beads, the cationic anti-color agent comprises cationic guar gum and cationic polyacrylamide in a mass ratio of 1:(1~5).

[0006] In the aforementioned color-mixing prevention type scented booster beads, the wall material of the essence microcapsule contains melamine resin and plant protein.

[0007] In the aforementioned color-mixing prevention type scented booster beads, the plant protein comprises at least one of soy protein and pea protein.

[0008] In the aforementioned color-mixing-preventing scented booster beads, PVA or polyethylene oxide is used as the material for the water-soluble film.

[0009] In the aforementioned color-mixing-preventing scented booster beads, the ratio of the mass of melamine resin to plant protein in the essence microcapsule is 1:(3~7).

[0010] In the aforementioned color-mixing-preventing scented booster beads, the ratio of the mass of the essence to the anionic surfactant in the essence microcapsule is 1:(2~3).

[0011] The present invention provides a method for manufacturing color-mixing-preventing scented booster beads used in the production of the color-mixing-preventing scented booster beads described in a second example of the present invention. The manufacturing method is as follows: Step S1 involves obtaining an intermediate material by packaging the essence microcapsules with a second encapsulation film, The process includes step S2, which involves mixing an intermediate material with a cationic anti-coloring agent, packaging the intermediate material and cationic anti-coloring agent with a first encapsulation film, and then mixing them evenly to obtain the color-mixing-preventing scented booster beads.

[0012] In the method for producing the color-mixing-preventing scented booster beads, the method for producing the essence microcapsules includes the steps of adding melamine resin, plant protein, essence, and an anionic surfactant to water, mixing them uniformly by high-speed stirring at a temperature of 50°C, and then drying them to produce the essence microcapsules. [Effects of the Invention]

[0013] The color-mixing prevention type scented booster beads of the present invention can achieve the following effects of the invention. The color-mixing prevention type scented booster beads form a multilayer structure by packaging the essence and anionic components in essence microcapsules, and packaging the essence microcapsules and cationic anti-color-mixing agents in a second encapsulation film and a first encapsulation film, respectively. This effectively prevents the cationic and anionic components within the color-mixing prevention type scented booster beads from binding. When using the color-mixing prevention type scented booster beads, the internal components can be released sequentially. Specifically, by releasing the cationic anti-color-mixing agent first, color mixing is prevented, and by the essence microcapsules adhering to clothing, the essence within the essence microcapsules is released during washing, thus preventing one function (color-mixing prevention function or essence release function) from affecting another function (essence release function or color-mixing prevention function). [Modes for carrying out the invention]

[0014] This invention provides a color-mixing prevention type scented booster beads and a method for manufacturing the same. In order to explain the object, technical matters, and effects of the invention in more detail and clearly, the matters of the invention will be explained in more detail below with reference to specific examples. It should be noted that the following specific examples are for illustrative purposes only and do not limit the invention.

[0015] In a first example of the present invention, anti-cross color scented booster beads are provided. The anti-cross color scented booster beads include a first encapsulation film and a second encapsulation film arranged in an inward-outward direction. Essence microcapsules are encapsulated within the second encapsulation film. A cationic anti-cross color agent is encapsulated between the first and second encapsulation films. The manufacturing materials for the first and second encapsulation films are water-soluble materials. The core material of the essence microcapsules includes an essence and an anionic surfactant. The cationic anti-cross color agent includes at least one of cationic guar gum and cationic polyacrylamide. The first encapsulation film dissolves in water in 2 to 4 minutes, and the second encapsulation film dissolves in water in 1 to 1.5 minutes.

[0016] By controlling the dissolution time of the first and second encapsulating films in water, the release time of the functional components of the color-mixing prevention scented booster beads can be matched to the washing machine's wash cycle. The main role of the cationic anti-color agent is to prevent color mixing by binding with the anionic dyes that have been washed off, thereby preventing the anionic dyes from adhering to other garments. When in contact with water, the cationic anti-color agent can be completely released within 2-4 minutes. This time corresponds to the time it takes for the anionic dyes to be washed off by detergent, etc. After the first encapsulating film dissolves, the second encapsulating film dissolves in water, releasing the essence microcapsules. At this time, the cationic anti-color agent fully performs its function and is completely consumed, significantly reducing its impact on the anionic surfactant within the essence microcapsules.

[0017] The first and second encapsulating films are water-soluble films, and when the parameters of the water-soluble films are the same, the thicker the water-soluble film, the longer the time it takes for the water-soluble film to dissolve in water. The main materials of the water-soluble film can be PVA, polyethylene oxide, etc.

[0018] Preferably, the cationic anti-color agent comprises at least one of cationic guar gum and cationic polyacrylamide. Positively charged groups are formed on the molecular chain of the cationic guar gum. These positively charged groups and anionic dye molecules are bonded together by electrostatic action, forming large aggregates or insoluble complexes. This reduces the dissociation and movement of dye molecules during washing, reduces the amount of dye molecules entering the washing solution, and prevents the dye color from adhering to other garments (color mixing). Positively charged groups are also formed on the molecular chain of the cationic polyacrylamide. Charge neutralization occurs between these positively charged groups and negatively charged dye colloid particles, resulting in the destabilization of the dye particles. Furthermore, multiple dye particles are linked together by adsorption bridging, forming large flocs. This promotes the precipitation and separation of the dye in the washing solution, reducing the movement of the dye between fabrics and reducing dyeing.

[0019] Preferably, the cationic anti-mixing agent comprises cationic guar gum and cationic polyacrylamide in a mass ratio of 1:(2-4). By using these two cationic anti-mixing agents simultaneously, a better anti-mixing effect can be achieved.

[0020] Preferably, the wall material of the essence microcapsules contains melamine resin and plant protein. By adopting melamine resin and plant protein, the essence microcapsules can be given good adhesion to clothing, and it can be ensured that the wall material of the essence microcapsules obtained by manufacturing has a predetermined structural strength in water. On the other hand, when washing, the essence microcapsules do not release a large amount of anionic components and do not weaken the effect of the cationic anti-mixing agent. In addition, the essence microcapsules can be bound to clothing more, and when the clothing is dried, the essence microcapsules burst due to friction, ensuring the release of components such as essence and enabling the fragrance to be continuously released. Also, since melamine resin and plant protein are not anionic components, they do not bind to the cationic anti-mixing agent and can weaken the action of the cationic anti-mixing agent.

[0021] Preferably, the plant protein contains at least one of soy protein and pea protein. Since legume protein has gel and emulsifying properties in the microcapsule delivery system, the shell structure can be further improved.

[0022] Preferably, the mass ratio of melamine resin to plant protein in the essence microcapsules is 1:(3 - 7).

[0023] Preferably, the mass ratio of essence to anionic surfactant in the essence microcapsules is 1:(2 - 3).

[0109] The performance of each color-mixing-preventing scented booster bead manufactured in proportion to the above embodiment is measured.

[0110] 1. The method for measuring the color mixing prevention effect is as follows: Three pieces of cloth measuring 60cm x 60cm and in different colors (red, orange, and blue) are placed in a 2L beaker. Then, one color-mixing prevention scented booster bead (approximately 12g) and 5g of detergent are added to the beaker. Next, 1L of water is poured in and the mixture is stirred to simulate the washing process. A white National Standard cotton fabric is placed in the beaker as a companion laundry cloth, and after simulating washing for 30 minutes, the companion laundry cloth is removed, rinsed twice, and then dried. The color mixing of the companion laundry cloth is observed, and the color difference of the companion laundry cloth before and after washing is measured using a colorimeter (select any 5 points and calculate the average value of these 5 points). The smaller the color difference value, the lower the degree of color mixing.

[0111] 2. The method for measuring dissolution time is as follows: Pour 500 mL of pure water into a 1 L glass bottle at room temperature. Next, insert a stirring paddle into the center of the water and adjust the rotation speed of the mechanical agitator to 250 ± 2 rad / min. Finally, place one color-matching-preventing scented booster bead (approximately 12 g) into the beaker and start a stopwatch to record the time required for the sample to completely dissolve in the water.

[0112] The results obtained from measuring the color mixing prevention effect are shown in Table 1. The results obtained from measuring the dissolution time are shown in Table 2.

[0113] [Table 1]

[0114] [Table 2]

[0115] As shown in the results above, compared to other examples and proportionality, Example 1 exhibits better color mixing prevention, shorter dissolution time, and superior overall performance.

[0116] Compared to Example 1, the longer dissolution time of the first encapsulation film in Examples 2 and 3 results in a slower release rate of the cationic anti-coloring agent, leading to poor color mixing prevention during washing.

[0117] Compared to Example 1, the difference between Example 4 and Example 5 lies in the compounding ratio of the cationic anti-mixing agent. Measurements of the anti-mixing effect show that the anti-mixing effect is somewhat reduced in Examples 4 and 5. This explains why the anti-mixing effect is best when the mass ratio of cationic guar gum to cationic polyacrylamide is 1:3.

[0118] Compared to Example 1, the difference in Example 6 is that the dissolution time of the first encapsulation film is shorter. According to the results of measuring the color mixing prevention effect, the color mixing prevention effect of Example 6 is reduced to some extent. This is because, due to the shorter dissolution time of the first encapsulation film, the color mixing prevention components are released in advance, and some of the color mixing prevention components become ineffective.

[0119] Compared to Example 1, the difference between Example 7 and Example 8 lies in the different components of the cationic anti-mixing agent. In Examples 7 and 8, only one cationic anti-mixing agent is used, and the anti-mixing effect in Examples 7 and 8 is lower than that of Example 1. This explains why a better anti-mixing effect can be achieved by using a combination of two cationic anti-mixing agents.

[0120] Compared to Example 1, the difference in the proportionality 1 model is that the dissolution time of the first encapsulation film is shorter. Measurements of the color mixing prevention effect show that the color mixing prevention effect of proportionality 1 is somewhat reduced. This is because the rapid dissolution rate of the first encapsulation film causes the rapidly released color mixing prevention components to combine with the anionic detergent, affecting the color mixing prevention effect.

[0121] Compared to Example 1, the difference in Ratio 2 is that the dissolution time of the first encapsulation film is longer. Measurements of the color mixing prevention effect showed that the color mixing prevention effect of Ratio 2 was somewhat reduced. This is because the dissolution time of the scented booster beads is considerably longer, resulting in a longer release time for the anti-color mixing agent. At that time, some of the dyes are bound to the companion laundry cloth.
