Abstract

A dry cleaning system and method, in which specially designed or modified machinery is used in conjunction with a specific solvent which is derived from an organic/inorganic hybrid (organo silicone). In this class of organo silicones is a group known as cyclic siloxanes. The cyclic siloxanes present the basis for material composition of the solvent chemistry which allows this dry cleaning system to be highly effective. The cyclic-siloxane-based solvent allows the system to result in an environmentally friendly process which is, also, more effective in cleaning fabrics and the like than any known prior system. The siloxane composition is employed in a dry cleaning machine to carry out the method of the invention. In a preferred embodiment, the method comprises the steps of loading articles into a cleaning basket; agitating the articles and the siloxane composition in which they are immersed; removing most of the siloxane composition; centrifuging the articles; subjecting the articles to a partial vacuum pressure and elevated temperature; and removing the articles from the basket after cooling the articles and returning the pressure to ambient.

Invention Description (/) «Technology of dry cleaning of Ming cage clothing, lions, fabrics and their likes. The present invention is particularly related to a method and apparatus for dry cleaning cloth using a solvent not currently used in a dry cleaning machine. The invention further relates to a dry cleaning device, in which a solvent based on a sand substrate is used, which has a desired flash point level (over 140 degrees Fahrenheit) and a fabric safety quality (non-polar color and non-shrinking) for a special dry cleaning method and Excellent solubility in fatty acids, oils and oils. Dry cleaning is a major industry worldwide. There are more than 40,000 dry cleaning shops in the United States alone (most of which have multiple locations). The dry cleaning industry is a basic industry that is economical. Many types of clothing (and other items) require dry cleaning to maintain cleanliness (removal of body fat and oil) and style (no shrinkage or discoloration). The commonly used solvents up to now, perc < 3perc, have a number of disadvantages, including toxicity and odor. Machines currently in common use are specially manufactured to use Perc. This is another limiting factor for this industry. Another problem in this field is that the systems currently in use require different treatments for different fabrics to prevent damage to the fabrics during the dry cleaning process. Conventional techniques for dry cleaning include the use of different solvents and appropriate machines to perform the rinsing. A solvent commonly used in the past is perchloroethylene (collectively referred to herein as Perc). Perc has the advantages of a good washing solvent, but the disadvantage is that it is destructive to health and the environment (that is, it is associated with many types of cancer and is destructive to underground water and aquatic life). Perc is no longer allowed in some regions. In addition, other solvents have been tried and used in the past, such as petroleum base solvents, ethylene ether and esters. Compared with the results obtained by perc, these various solvents have doped cleaning results and problems with cloth / fabric compatibility. Please read the notice before filling in this page.

Description of the invention (1) Another object of the present invention is to provide a dry cleaning method in which the solvent does not damage the object to be washed. Another object of the present invention is to provide a Dry-cleaning solvents that do not deposit and / or accumulate on clothing and reduce allergies. Another object of the present invention is to provide a dry-cleaning solvent with unique burning characteristics, where the flash point and the flash point of the solvent differ by at least 10 degrees Fahrenheit, and the solvent The flash point and the flash point will self-extinguish. Another object of the present invention is to provide a dry cleaning solvent that can be heated to more than room temperature (over 70 degrees Fahrenheit) to improve and accelerate the washing process, but will not damage the cloth. Another object of the present invention is to provide a dry-cleaning solvent having a surface tension of less than 18 dyne / square cm, which makes it easier to penetrate cloth fibers and remove dirt, and it is easier to remove the solvent from the cloth. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below and described in detail with the accompanying drawings as follows: v // FIG. 1 is a drawing A block diagram of a dry cleaning process according to a first preferred embodiment of the present invention. In the embodiment, the dry cleaning method is unique, and in particular, a cyclospheric oxygen laboratory which is well-known for makeup, mouthfeel and traditional musical agents is used. These cyclosand oxygen plants are more specifically the well-known octamethyl-cyclotetrasiloxane (tetramer) and decamethyl_cyclopentasiloxane (pentamer).

Description of the Invention (+) Its simple form is not entirely suitable for dry cleaning. In the dry cleaning method of the preferred embodiment, the tetramer and pentamer are modified. The modification method is to add a soil suspension additive to prevent the re-deposition of dust during rinsing and washing in tetramers and pentamers, a detergent for hydrophilic stains, and to the bacteria and all bacteria present in all clothes. Other types of microorganisms have fungicides. The steps of the dry cleaning method of this preferred embodiment are specifically described below. Step 1 Place the laundry or other items to be dry-cleaned in the horizontal rotating and stirring washing basket of the upright washing dryer (know-how). The bobbin has a large number of holes or rows of holes in the bobbin, and it is preferred that each hole has a diameter of about 1 / 8-3 / 8 inches. Step 2 The rinsing process starts with a solvent composed of a tetramer and a pentamer of cyclosiloxane. The preferred composition ratios of tetramer and pentamer are 80% and 20% (weight percent), respectively. The additives that modify the above composition will be added before the rinsing process and need not be part of the solvent composition. The additives used are detergents and suspending agents, which cause the solvent to complete a complete laundry washing process. Solvent is poured from a storage tank into the 淸 basket. The items to be washed are stirred, such as mechanically rubbing clothes, to dissolve the penetrant to release dirt, debris and body oil from the fabric fibers, and the stirring must be continued for 3-10 minutes or more. The solvent is then drained from the rinsing basket and passed through a filtration system of activated carbon and / or clay to remove impurities entering the solvent during the rinsing process and back to the storage tank. Step 3 Rotate the cleaned items at 350-1, 000 rpm (one revolution per minute), preferably at 450-750 rmp, rotate for 3-5 minutes to 7 ------ -I ---- · I — II III Order · -----! · ^ (Please read the precautions on the back before filling out this page) The paper size applies to Chinese National Standard (CNS) A. 丨 Specification (21〇χ 297 mm) 475020 Λ7 B7 5095pif2.doc / 009 V. Description of the invention ( s) (Please read the notes on the back before filling out this page) Spin it. In this operation, no more than 3% of the solvent remains in the cleaned objects. At high speeds, the solvent is quickly removed by the centrifugal force generated by rotating the washing basket. Solvents with very low surface tension can be used to maximize the removal efficiency by the centrifugation produced by the spinning process. Step 4 The clothes are tumbled in a washing basket and heated at πο-Μ0 ° F. • It is accomplished by heating the air in the basket with a line of 圏 and passing a rotating fan to transfer a compressed vapor. When the laundry is tumbled and heated in the 淸 wash basket, a partial vacuum is generated in the machine, which is a negative pressure between 500-600 mmHg (atmospheric pressure is 760 mmHg). During heating, the solvent evaporates and is sent to the condensing coil by the circulating air, which condenses the solvent in a vapor state into a liquid state for removal from the main air stream. After a period of time, usually 15-20 minutes, all solvents will be removed from the laundry. Step 5 terminates the heating process and starts the cooling step of the laundry. Its temperature dropped from 140 degrees Fahrenheit to below 100 degrees Fahrenheit. This cooling step is performed by removing the vacuum and circulating air through the condensation coil until the step is completed. When the clothes are close to body temperature or do not cause secondary wrinkles, the 'washing step is completed when removed from the machine. Removing clothing at high temperatures will cause wrinkling. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs.
