Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for washing items to be washed, particularly cotton and cotton analogues made by blending polyester fiber or the like with cotton.

(Prior art) The washing method has traditionally been the sea urchin 7 cleaning method,
There is a dry cleaning method. Conventionally, cotton and cotton analogues made by blending cotton with polyester fiber or the like are washed with water using a wet cleaning method.

In other words, put the laundry in the washer of the washing machine and rotate it at 60°.
Massage the skin with soapy water while applying internal and external heat. After massaging for 10 to 15 minutes, drain the water, rinse with fresh water 2 to 3 times, then dehydrate and dry. There is.

(Problems to be Solved by the Invention) According to the water washing method described above, when the item to be washed is extremely dirty, it is washed at high temperature, but if the temperature is too high, de-staining phenomenon occurs, and water It has the disadvantage of shrinkage because it is washed, squeezed, and then dried. or,
When draining the liquid, there is a disadvantage that the detergent contained in the waste liquid is undesirable from a pollution standpoint, and in particular, it is undesirable for nuclear waste to be contained in the waste liquid.

Also, dry cleaning tends to remove oily stains, but
Water-soluble stains are difficult to remove.

Therefore, dry cleaning cannot remove water-soluble stains from cotton and cotton analogs.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to provide a method for washing cotton and cotton-like materials by blending cotton with polyester fibers, etc., without de-dying or shrinking. The technical means of the present invention to solve this technical problem is to wash clothes made of cotton and cotton analogues made by blending polyester fibers etc. with cotton, into the washer of a washing machine. A liquid prepared by emulsifying and dispersing water, a low alkaline agent, and a soap such as a high HLB activator for washing in a solvent such as perchlorethylene is sprayed onto the items to be washed in advance, or The liquid is pooled in the washer and the dirt is dispersed in the solvent.Then, the items to be washed are squeezed out by high-speed dewatering, and the deliquified items are soaked in a soapless fresh water solution. This washing method is characterized by rinsing in the same way with a solvent and then drying.

(Effects of the invention) According to this technical means, stains were removed from clothes made of cotton and cotton blended with polyester fibers, etc., by washing with water, but compared to washing with water, the clothes do not shrink or come off easily. No staining,
It has the characteristic that it can be washed and dried in its original shape, greatly reducing the labor of pressing, and it can be washed at low cost because it does not require contaminated wastewater that causes pollution problems (and does not require expensive water). be.

(Example) The embodiments shown in the drawings will be described below.

First, I will explain the washing machine.

In Figure 1, (]) is the inner shell of the washing machine, that is, the washer, and the washing liquid used here is passed through the pipe (3).
The liquid is transferred from the pipe (4) to the distiller (5) through the button trap (2), condensed in the still condenser (6) and the secondary condenser (7), and then freshly distilled from the water separator (8). It is returned to the tank (9) in a regenerated state.

The overflow here is supplied to the base tank (11) through the bypass (10).

Therefore, the washing liquid used in the washer, for example, a fluorine solvent with a low boiling point of 48°C, is sufficiently cooled, and the distilled solvent is rapidly cooled and recovered by cold water in the primary condenser (6), and is recovered in the secondary condenser (7). It is further cooled and recovered using low-temperature water, making it easy to recover the distillation solvent.

Furthermore, in the rinsing step, the liquid is pumped from the base tank (11) through the pipe (13) to the filter (14) using the pump (12).
and placed in the washer (1).

Also, in the drying process, the air inside the washer (1) is filtered with fibers by a lint screen (15),
16).

The solvent recovered by the low temperature condenser (16) is heated by an oil heater (17) and supplied into the washer (1).

In addition, (1st) is a soap tank, and the pipe (19th) is a soap tank.
) the soap is added to the solvent from the tank (9) which is sent by the tank (9).

The washing process generally follows the sequence shown in FIG.

The washing liquid contains water and low P in perchloroethyl solvent.
Add 3% of H alkaline agent, high HLB activator for water washing, etc.
Emulsified and dispersed mixture is used.

Examples of solvents include perchloroethyl solvent, fluorine, ethane, petroleum, and the like.

As described above, a product in which fine particulate water and a water-soluble high HLB cleaning agent are dispersed and mixed in a park solvent using emulsion technology creates a state of washing with water locally and finely in a park solvent. By taking advantage of its unique construction and dry properties, it can be used to wash clothes without bleaching or shrinking, and it does not remove water-soluble, inorganic (mud, dust, etc.) oil-based substances, as well as salts and sugars that were previously thought to be difficult to remove. Improved cleaning power for materials.

Now, in the present invention, first, the above-mentioned liquid is sprayed onto the object to be washed in the washer to allow it to soak into the object sufficiently, or this is omitted and washing is carried out in the washer for 2 to 3 minutes. (Refer to A and G) For this, we use a material that does not pass through the filter (14) mentioned above, but since dirt will come out, the solvent is collected and regenerated and the tank (
Turn to 9).

Thereafter, centrifugation is performed in the washer (1) to remove and drain the liquid for 1 minute. (See B) Next, filter (14)
Do laundry while taking a Niagara shower through
Rinse for an additional 2 minutes. (See C, D, H, I) Next, the liquid is removed by centrifugation and drying begins.

This time is 10 to 15 minutes. (See E and F) According to the device method described above, all of the fallen dirt and solvent can be distilled, and the solvent in the base tank is always maintained as a clear, soap-free solvent like fresh water. It is something that can be done. In addition, it can be rinsed with the solvent, and any remaining residue can be completely rinsed off with the freshly distilled no-soap solution in the tank (9), and after drying, it can be treated with after-treatments such as softness, antistatic, resin, and water repellency. do.

In any case, the present invention is characterized in that cotton and cotton-like materials can be washed without shrinkage or discoloration by changing the washing method of dry cleaning such as perchlorethylene to washing with water.
