Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laundry finishing agent, and more particularly to a laundry finishing agent which can improve the feeling of tension and the washing and washing power when it is thinly attached to clothes.

[0002]

2. Description of the Related Art Conventionally, gluing (finishing treatment) has been performed at the end of laundry washing, and starch paste is mainly used as a natural raw material. Before carrying out, first, a general washing process is shown in FIG.
Will be described with reference to. First, a so-called "washing" step of washing the article to be washed (clothing) with water containing a detergent is performed, and when the above "washing" is completed, rinsing is performed a plurality of times. When the rinsing is finished, the water is once dehydrated and then water is supplied again to add the above finishing agent and the finishing agent treatment is performed to improve the feeling of tension of clothes and the washing and washing power. Regarding the timing of adding the finishing agent,
It is not always necessary to dehydrate the rinse water as described above, and it may be added at the same time, for example, during the second rinse step.

Next, the above starch paste will be described. First, immerse the clothes in a concentration of about 3% starch glue in about 10 to 30 liters of water, which is smaller than the amount of about 50 liters when washing, and attach it to the clothes.
After that, it is lightly dehydrated and dried.

[0004]

However, the above method requires a large amount of sizing agent (for example, 250 to 3).
On the other hand, a large amount of sizing agent that did not adhere to clothes is discarded during drainage, which causes a large loss in terms of environment and economy, and is extremely inefficient. Also, a sizing agent prepared by emulsifying polyvinyl acetate so that it can easily stick to fibers is commercially available. This gives a feeling of tension to clothes, but does not have much washing power.

In view of the above, the present invention improves the washing and washing power in addition to the conventional feeling of gluing on clothes, and effectively attaches the finishing agent to the clothes to finish the clothes efficiently in a small amount. It is an object of the present invention to provide a laundry finish capable of

SUMMARY OF THE INVENTION In the present invention, first, what has been conventionally subjected to a washing finishing step in a neutral water bath is replaced with carboxymethyl cellulose having a high performance of preventing stain transfer to fibers. The cellulosic polymer of is cationized with a quaternary ammonium salt or the like, and is effectively adsorbed to the negatively charged fiber in a water bath, thereby giving a feeling of tension of clothes and washing power of washing. It is what

Further, the present invention is one in which a finishing process for washing in a neutral water bath is carried out in the past, but by anionizing the finishing agent, natural fibers such as cotton which are negatively charged, and polyester. It is also characterized by effectively adsorbing to such a chemical fiber and imparting a feeling of tension and washing power of clothes. That is, when the anionized laundry finishing agent is adsorbed on the fibers in a water bath and stains are attached after drying, the stains are easily separated from the fibers by the negatively charged fibers and the anionic finishing agent by the washing water and the cleaning performance is improved. It is a dramatic improvement.

FIG. 1 shows the relationship between the amount of glue applied and the rigidity (tension). Carbooxymethyl cellulose (CMC), which is a cellulosic polymer, has a small amount of adhesion to cotton compared with polyvinyl alcohol (PVA), and a feeling of tension is recognized. In addition, polyvinyl acetate has the same effect as PVA. Starch has almost no tense feeling at this concentration.

FIGS. 2 and 3 show the cleaning ratios of the concentration of the glue liquid and the concentration of the cationized glue (finishing agent) liquid. FIG.
As is clear from FIG. 3 and FIG. 3, the detergency is cationized and the effect is recognized in an amount of 1/10 to 1/20. Conventionally, 10 g of the sizing agent was dissolved in 1 liter of water before use. The amount you had was 1g or 0.5g. That is, a lot of water is required for automatic stirring in the washing machine.

By mixing 1: 1 to 10: 1, it is possible to obtain an appropriate hardness (tension feeling) without impairing the detergency.

(Embodiment 2) In Embodiment 1 described above, a preformed salt laundry finishing agent is dissolved in water to improve the feeling of tension on clothes and the washing and washing power. In the present embodiment, the laundry finishing agent is not in a powder state but is solidified and used.

Specific examples of means for solidifying include, for example, a method in which a powdery salt-like laundry finishing agent is once dissolved in water and then water is evaporated to obtain a solid material. However, an example will be described below.

In the case of the present embodiment, non-ionized PVA is used as a base material for solidifying the liquid of the cationized cellulose type polymer.

FIG. 4 shows the solubility of PVA in water temperature. The solubility varies depending on the saponification degree of PVA. When the saponification degree is 86 to 93%, it dissolves regardless of the water temperature, but at 75 to 80%. The solubility decreases as the water temperature rises. Further, if the saponification degree is lowered, the solubility is lowered.
Taking advantage of this characteristic, a finishing agent (cationized CMC
It is possible to produce a solid material with added saponification, etc., and if PVA with a high degree of saponification is washed in advance to form a solid material, a laundry finishing agent that is not affected by solubility even with temperature can be obtained. Obtainable.

According to the present embodiment, by solidifying the laundry finishing agent, it is possible to automatically add the laundry finishing agent to the water by setting the solid matter in the running water path of the washing machine. Therefore, it is not necessary to add a laundry finishing agent each time the laundry is washed, which is very convenient.

Next, the case where an anion is used as a laundry finishing agent will be described below, and a specific form thereof will be described in the third embodiment.

The present invention is intended to efficiently utilize a laundry finishing agent capable of improving the feeling of tension and the washing and washing power of clothes, and basically, it is just to improve the feeling of tension of clothes. It is configured to include a component for causing the component and a component for anionizing the component.

Here, as a system of components for improving the feeling of tension of clothes, starch-based, cellulose-based, polyvinyl alcohol (PVA) -based, polyglycerin-based, vinyl acetate-based ones are considered. The cellulose type, polyvinyl alcohol type, and polyglycerine type are mentioned as those which easily react with an organic acid (for example, monochloroacetic acid) used for anionizing the finishing agent.

As described above, when the anionic component is added to the laundry finishing agent, as compared with the case where the cationic component is added to the laundry finishing agent as shown in the first or second embodiment, clothes, etc. Regarding the adsorption of
Although somewhat inferior, it becomes possible to easily remove dirt during cleaning.
