Description

The present invention relates to a method for removing dirt and stains from a woven fabric.

Certain soils are not always effectively removed, for example, during the normal washing of laundry in a washing machine. Such soiling means a pretreatment which means a washing treatment performed before a normal laundry washing step in the present invention, and / or a washing treatment which is carried out after a normal laundry washing step in the present invention. By performing the post-processing, it can be more effectively removed. The present invention relates to a post-processing cleaning method.

European Patent Application No. 20 published November 12, 1986
No. 0807 discloses an iron for washing laundry while ironing, ie for post-treatment. To this end, a recess may be made in the housing of the iron to accommodate the brush (3).
Line 22 on page to line 1 on page 4). The iron is also provided with vacuum cleaning means. However, it has not been suggested to use a cleaning composition to enhance this cleaning method.

U.S. Pat. No. 3,748,268, issued Jul. 24, 1973, discloses a detergent composition for removing dirt and stains. The composition is mainly for cleaning carpets, but also mentions textile fabrics. This patent states that a pre-treatment cleaning method involving the action of rubbing lightly to help the detergent composition soak into the soil can be used to remove the soil using a dry absorbent cloth. Suggests. Thereafter, water is applied and, optionally, the cleaning operation is completed using an absorbent material to remove dirt and residue of the composition.

However, many textiles, especially those made from silk and wool, are much more delicate than carpets. If the gentle rubbing action applied to the carpet is applied to the fabric, it is considered to be a vigorous rubbing action. However, very mild treatments that are acceptable for delicate fabrics may not completely remove the soil.

German Patent Application No. A-43 published August 11, 1994
03 454 describes a stain removal method and a stain removal set. The method includes applying a soil remover to the soil. Thereafter, the soil is activated and washed away with the hot water. Hot water is applied by heating the water in the sponge with a hot iron. In this cleaning method, water is applied to a large area of the fabric, that is, at least an area corresponding to the area of the sponge. As a result, new greasy soil spreads on the fabric rather than being removed. Also,
The presence of a sponge between the fabric and the iron prevents heat from effectively reaching the dirt and stains. Simply applying more heat with an iron will cause the sponge to burn or melt.

It is an object of the present invention to apply the detergent composition to stains and stains, place an absorbent layer adjacent to one side of the stain or stain portion of the woven fabric, and reduce some of the stains and stains. To provide a more effective method for treating dirt and stains on a woven fabric, comprising applying heat, pressure, or heat and pressure to absorb all of the absorbent layer. .

Another object of the present invention is that at the end of this washing process the fabric is dry and ready to wear.

SUMMARY OF THE INVENTION The object of the present invention is achieved by applying heat and / or pressure to the opposite side of a stained or stained portion of a woven fabric, preferably in the presence of a hydrophilic solvent or water.
Without wishing to be bound by theory, it is believed that the application of heat and / or pressure changes physical properties, such as viscosity, to improve the cleaning effect. Due to such a change in properties, the detergent composition penetrates better into stains,
The cleaning effect is improved. In addition, when heat is applied, all remaining moisture evaporates, and the woven fabric dries.

In a preferred embodiment of the present invention: (a) applying the detergent composition to the stains and stains, forming an absorbent layer adjacent to the stains and stains of the woven fabric, and removing some of the stains and stains; Or a first means for transferring everything to the absorbent layer, and then (b) applying a hydrophilic solvent or water to the stained or stained portion of the woven fabric to thereby remove the stained or stained portion of the woven fabric. A method of treating stains and stains on textiles, including the step of placing an absorbent layer adjacent to the second layer and transferring some or all of the stains and stains to the absorbent layer. Is provided.

The second means for transferring soil to the absorbent layer is preferably by applying heat, more preferably by using a hand-held household iron. The first means for transferring some or all of the stains and stains preferably includes a step of rubbing the stains and stains, a step of extruding the stains and stains, or a step of brushing the stains and stains. .

DETAILED DESCRIPTION OF THE INVENTION The most preferred cleaning methods include: (a) applying the detergent composition to stains and stains, forming an absorbent layer adjacent to the stained and stained portions of the fabric, and some of the stains and stains. (B) applying a hydrophilic solvent or water to the stained or stained portion of the woven fabric, and then applying a hydrophilic solvent or water to the stained or stained portion of the woven fabric. And a step of applying heat to the stained or stained portion of the knitted fabric. Heat or pressure, or both, can be applied by any means, but most preferably with a hand-held tool such as an iron. A conventional iron with a hot plate fixed to the body is highly preferred as a hand-held tool. The hot plate is
Heating is most commonly performed by electrical means, and may have means for adjusting the temperature. Water or steam may be supplied by an iron. Most preferably, the absorbent layer is placed on a flat surface, such as an ironing board, and the soiled or stained fabric is spread flat over the absorbent layer in contact with the absorbent layer. By doing so, the stains and stains of the textile can be easily ironed in order to transfer the stains and stains completely or substantially completely to the absorbent layer. Ironing is preferably carried out at a temperature of 40 to 180 ° C.

Another tool for applying heat or pressure is a heat roller or any other heat applicator. The roller or applicator may be equipped with a detergent composition supply means.

Suitable applicators include European Patent Application A

A steam iron with a sprayer is also suitable. According to this specification, the detergent composition may be pooled in an iron and delivered directly to the fabric by a sprayer.

While not wishing to be bound by theory, it is believed that hydrophobic dirt is first rendered hydrophilic by applying the detergent composition with slight rubbing in some cases. Then, if necessary, apply water again while gently rubbing. Soil is removed by placing the soiled fabric adjacent to the absorbent layer. The stain rendered hydrophilic by this treatment moves to the absorbent layer.

Examples of these polymeric materials are described in U.S. Pat.
No., U.S. Pat.No. 4,076,663, U.S. Pat.No. 4,093,776,
It is disclosed in U.S. Pat. No. 4,666,983 and U.S. Pat. No. 4,734,478.

The most preferred polymeric materials for use in making the hydrogel-forming particles are partially cross-linked polymers of partially neutralized polyacrylic acid, and their starch derivatives. The hydrogel-forming particles comprise from about 50% to about 95%, preferably about 75%, of neutralized, slightly reticulated crosslinked polyacrylic acid (i.e., poly (sodium acrylate / acrylic acid)). Most preferred.

As mentioned above, the hydrogel-forming absorbent polymer comprises:
It is preferable to crosslink slightly in a network. The reticulated crosslinks help to make the polymer substantially insoluble in water, and it also determines, in part, the absorbency of the precursor particles, the extractable polymer content, and the resulting macrostructure. Methods for cross-linking polymers in a network, and general network cross-linking agents, are described in more detail in the above-referenced U.S. Patent No. 4,076,663 and German Patent Application No. A-4020780 (Dahmen). I have.

Although the hydrogel-forming absorbent polymer can have a wide variety of sizes, certain particle size distributions and sizes are preferred. For the purposes of the present invention, for hydrogel-forming absorbent polymers in which the largest dimension / smallest dimension ratio is not as great as fibers (eg, granules, flakes, or fines), the particle size is sieved. It is defined as the size of the precursor particles measured by the split test. Therefore,
For example, hydrogel-forming absorbent polymer particles held on a # 30 standard sieve with 600 micron openings have a 60
Considered to have a particle size greater than 0 microns, 600
Hydrogel-forming absorbent polymer particles that pass through a # 30 sieve with micron openings and are retained on a # 35 standard sieve with 500 micron openings have a particle size of 500-600 microns. It is believed that the hydrogel-forming absorbent polymer particles that pass through a # 35 sieve with openings of 500 microns are considered to have a particle size of less than 500 microns. Preferred hydrogel-forming absorbent polymers useful in the present invention are those in which the particles are
It ranges in size from about 20 microns to about 2000 microns, more preferably from about 20 microns to about 1000 microns.

Also, for the purposes of the present invention, the mass median particle size of the hydrogel-forming absorbent polymer is important in determining the properties and properties of the resulting particles. The mass median particle size of a given sample of hydrogel-forming absorbent polymer particles is defined as the particle size that bisects the sample on a mass basis. Instead of mass median particle size, weight average particle size may be specified as a measure of particle size. The weight average particle size is the average particle size of the sample on a mass basis. The method for measuring the mass median particle size of the sample is described in the test method section below. The mass median particle size of the hydrogel-forming absorbent polymer particles is usually from about 20 to about 1500 microns, more preferably from about 50 to about 1000 microns. Preferred hydrogel-forming absorbent polymers useful in the present invention include:
The particles have a mass median particle size less than about 1000 microns, more preferably less than about 600 microns, and most preferably less than about 500 microns.

The particle sizes of materials such as fibers having a large maximum / minimum size ratio are typically indicated by their maximum dimensions. For example, when a hydrogel-forming absorbent polymer fiber is used in the present invention, the length of the fiber is used to indicate "particle size". (The denier and / or diameter of the fiber can also be specified.) In a typical embodiment of the hydrogel-forming absorbent polymer useful in the present invention, the length of the fiber is greater than about 5 mm, preferably about 5 mm. 10 to about 100 mm, more preferably about 10 to about 50 mm.

Preferred as the hydrogel-forming absorbent polymer particles of the present invention are those exhibiting a high absorbency value or a tea bag centrifugation ability value. Absorbency, or teabag centrifugation ability, refers to the ability of a polymer to absorb a liquid when the polymer is contacted with the liquid under free swelling conditions. TCC can vary significantly depending on the nature of the liquid to be absorbed and the manner in which the liquid is contacted with the polymeric material. For the purposes of the present invention,
The tea bag centrifugation ability is the amount of 0.9% saline absorbed by any given polymer. In the tea bag centrifugation ability test method described in the test method section below, the polymer substance 1 It is defined as grams of saline absorbed in grams. Preferred as the hydrogel-forming absorbent polymer particles of the present invention are those having a tea bag centrifugation capacity value of at least about 20 grams, more preferably at least about 25 grams, of saline per gram of polymeric material. Typically, the hydrogel-forming absorbent polymer particles useful in the present invention have a tea bag centrifugation capacity value of about 20 to about 70 grams of saline per gram of polymeric material. Mixtures of hydrogel-forming absorbent polymer particles having such relatively high absorption properties are particularly useful in the present invention. This is because an absorbent member formed from such particles can obviously hold a large amount of fluid.

For the other absorbent structure for the absorbent pad of the present invention, the above-mentioned granular superabsorbent material can be used, but a cohesive structure is formed from them. Such a "porous and absorbent polymeric macrostructure,
How to make them "is described in U.S. Pat.

No. 24, "Absorbent foam material for aqueous body fluids and absorbent articles containing such material"
Are also suitable for the present application.

Optionally, the absorbent structure may include some specific materials that have been developed to absorb oils and fats. One example of such a material is T-151 oil sorbent, a product of 3M (Minnesota Mining and Manufacturing, St. Paul, Minn.). T-151 sorbents, and similar absorbent materials, are non-woven webs typically made of polymeric fibers, such as polypropylene, polyethylene, poly-4-methylpentene, arylene, styrene, and copolymers thereof. And certain polyester polymers, such as polyesters, polyamides, and polycarbonates.

Methods Tea Bag Centrifuge Test The tea bag centrifuge test measures the tea bag centrifuge value, which is a measure of the liquid retention of the gelled material at hydrostatic pressure.

The superabsorbent material is placed in a "tea bag" and soaked in a 0.9% by weight solution of sodium chloride for 20 minutes and then centrifuged for 3 minutes. The ratio of the weight of liquid retained to the initial weight of dry superabsorbent is the absorbency of the superabsorbent.

Two liters of a 0.9% by weight solution obtained by dissolving sodium chloride in distilled water is poured into a tray measuring 24 cm × 30 cm × 5 cm. The height when filled with liquid should be about 3 cm.

The dimensions of the tea bag are 6.5 cm x 6.5 cm and are available from a company called Tican in Dusseldorf, Germany. The sachet can be heat-sealed with standard equipment for sealing plastic kitchen bags (eg VacuPak ₂ Plus from Krupp, Germany).

After carefully cutting a part of this tea bag,
Measure the weight. Place 0.200 g ± 0.005 g sample of superabsorbent material in tea bag. Thereafter, the tea bag is closed with a heat sealer. This is called a sample tea bag.

The empty tea bag is sealed and used as a blank.

Thereafter, each tea bag is held horizontally and the sample tea bag is shaken so that the superabsorbent material is evenly distributed in the bag. Place the sample tea bag and the blank tea bag on the surface of the saline solution and submerge them in a saline solution using a spatula for about 5 seconds so that the tea bag is completely wet. Get wet). Start the timer immediately.

20 sample tea bags and blank tea bags
After soaking for a minute, remove from the saline and
130 · Bosch 772NZK096 or equivalent centrifuge (diameter
230 mm) and attach each bag to the outer wall of the centrifuge. Close the centrifuge lid and start the centrifuge and increase the speed rapidly to 1,400 rpm. 1,400r centrifuge
Stabilize once with pm, then start the timer. After 3 minutes, stop the centrifuge.

Take out the sample tea bag and the blank tea bag and measure the weight separately.

The teabag centrifugation capacity (TCC) of a sample of the superabsorbent hydrogel-forming substance is calculated as follows.

TCC = [(weight of sample tea bag after centrifugation)-(weight of blank tea bag after centrifugation)-(mass of dry superabsorbent hydrogel-forming substance)] ÷ (dry superabsorbency) Material Weight) Mass Median Particle Size Measurement For the particle size distribution of the superabsorbent material, a sample of known weight is placed in a Let's mechanical sieving apparatus and shaken under defined conditions for a period of time. The mass of each sieve, and the fraction of the sample retained in the lower pan, is measured and reported as a percentage of the original weight of the sample.

100 g ± 0.5 g of the dried superabsorbent polymer substance is measured into a sample cup, and then the lid is closed.

Lay four sieves from bottom to top as follows. Stainless steel lower tray, No.325, No.100, No.5
0 and No.20. These are US sieve series (ASTM-E-11).
−61). The sample is transferred to the top of a series of sieves and the powder is spread evenly across the screen.
Place the stainless steel cover on the No. 20 sieve.

The stacked sieve is passed through a Let's test sieve shaker with a timer.
Place in place on Vivotronic VE1. The let's lid should fit as close as possible to the top of the shaker. Set the timer to 10 minutes and start the test. When the shaker has stopped, remove the overlaid sieves from the shaker.

Thereafter, the weight of each fraction retained on the sieve is measured to the nearest 0.0 g, for example, by various measurements.

It is important that this test be performed quickly to prevent the superabsorbent from absorbing moisture.

The mass median particle size of a given sample of hydrogel-forming absorbent polymer particles is defined as the particle size that bisects the sample on a mass basis. That is, half of the sample (by weight) will have a particle size smaller than the mass median particle size, and half of the sample will have a particle size larger than the mass median particle size. If the 50% mass value does not match the size of the US standard test sieve opening, a method of plotting the standard particle size (either retained on a sieve of a given opening size or The cumulative weight percent of the passing particle sample is plotted on a probability paper against the size of the sieve opening) is typically used to determine the mass median particle size. These methods for measuring the size of hydrogel-forming absorbent polymer particles are described in 1991.
