Description

SOFTENER WITH ANTISTATIC ACTION
Subject of the Invention
The invention relates to a softener product with antistatic action developed for use in the industrial laundry process.
State of the Art
The conventional or tunnel type washing machines are used for washing the textiles for the industrial laundry process at the laundry plants. The tunnel type washing machines are the systems allowing continuous washing, which enable the dirty textile product to enter at one end and exit in a clean state at the other end. In these machines, the dirty textile products are loaded in a continuous manner to the machine via a loading belt. The textile passes through the prewash and main wash compartments in order, it then reaches the rinse compartment, and after rinsing, it is subjected to a neutralization step where a softener is also used. Finally, the textile reaches the mangle/press step and is delivered automatically to the dryer. Although the number of compartments through which a product being subjected to the washing process passes varies, the tunnel type machines may be said to have generally 13 compartments. According to the common practice, the last 3-4 compartments of the tunnel are used for the rinsing and neutralization processes.
In the tunnel type washing machines, the clean water is not used for the textile product reaching the prewash compartment. The prewash step is intended to wet the textiles and to remove as much as possible the dirt on the textiles before the main wash; the water coming from the rinsing and press is used in this step. After the textile product has been transferred to the main wash compartment, part of the water is sent to drainage, and the water, which comes again from the rinsing, is introduced to the main wash compartment. The clean water input to the tunnel type machines occurs only via the last compartment and the water reaching the last rinse compartment is delivered towards the first compartment of rinse by way of reverse flow.
The rinse and press water is stored in the tanks after exiting the compartments, and in the mean time, the water is passed through simple filters in order to remove the particles in water. Nonetheless, the fuzz and fluff originating from the textiles remain in the water. Throughout the washing, the textile products contact the water that is used for rinsing different types of textile and said fluff possible to remain in the water may adhere to the white-colored textiles. Further, the structures like hair and body hair, in case they are not able to be removed with water, may also remain attached on the textile. Consequently, a washing product, which will confer antistatic property to the textile, is needed for the industrial laundry processes carried out in the tunnel type washing machines.
That the white textiles like quilt cover set and towel used in the hotels have a color referred to as ultra-white is of great importance from the perspective of the consumers. However, various softener agents used during the washing may cause the white textile to gray in the course of time. Accordingly, the development of a novel softener product that would not cause textiles to become gray is a further need.
According to the state of the art, the synthetic softeners with cationic content are used in the neutralization step. These softeners lack the desired level of antistatic action for repelling the fluff. Some laundry plants may increase the quantity of water used for rinsing, in order to prevent the fluff from adhering on the textile. However, this is not much preferred, as it would increase the amount of water use of the laundry plant.
After leaving the press, the textiles are transferred to the dryer. In the dryer, the textiles are exposed to high temperature and also to a mechanical action caused by the spinning process. Some fluff may detach from the textile during this spinning process. However, an exact opposite situation could also occur depending on the type of the textile and the structure of the fluff in the ambience. Moreover, the textiles such as linen and pillowcase may be subjected to a process of shaking out via the automated machines, while being transferred to the iron. This too may enable some of the fluff to be removed from the textile. Owing to the antistatic action conferred to the softener product developed within the scope of the invention, it will be made possible to prevent the structures such as fluff and hair from adhering on the textile product during the washing processes performed in the tunnel type laundry systems, without having to increase the amount of water used during the rinsing.
Object of the Invention
An object of the invention is to develop a softener product with antistatic property for use in the industrial laundry systems.
Detailed Description of the Invention
The invention relates to a softener product with antistatic action developed for use in the industrial laundry process.
The softener product according to the invention comprises at least one type of cationic surfactant, at least one type of agent for conferring antistatic property and at least one type of antifoam agent.
The product according to the invention comprises said cationic surfactant and said agent for conferring antistatic property at a total ratio of 4-25% by weight and said antifoam agent at a ratio of 0.01-0.2% by weight.
Within the scope of the invention, the use of the raw materials of the vegetable and/or synthetic quaternary ester groups such as methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate and/or dipalmitoylethyl hydroxyethylmonium methosulfate is preferred as the cationic surfactant. The cationic surfactants give a partial antistatic property to the textile. According to the state of the art, different raw materials from the silicone group may be employed to enhance the antistatic action. When the raw materials of silicone or nonionic origin are used alone, the transparent products are obtained, and these are not preferred by the users as they present a structure different from the currently used products. Besides, some of amino silicones with good softening properties cause the textiles to turn yellow when exposed to high temperature. This is a condition resulting from the side amino chain structures of amino silicones.
The use of the substances with silicone structure is preferred as the antifoam agent in the product developed within the scope of the invention. The substances with silicone structure further add antistatic action to the product according to the invention. In this way, the amount of foam likely to originate from the detergents during the use of the rinsing water for the prewash and main wash steps will be reduced. Reducing the foam amount will enhance the mechanical impact in the compartments. Moreover, the agent for conferring antistatic property present in the water will be able to continue exhibiting partial action during the washing also.
The product developed within the scope of the invention comprises as the agent for conferring antistatic property at least one of a mixture of fatty acid condensation product, amino-modified silicone polyether copolymer and polyoxyethylene triglyceride and a mixture of silicone polyether copolymer and polyalkylene glycol, or a mixture of several of the same.
An alternative embodiment of the product developed within the scope of the invention preferably comprises at least one type of dyestuff. In this way, it is possible to confer the desired color to the product.
An alternative embodiment of the product developed within the scope of the invention preferably comprises at least one type of essence. By the addition of the essence in normal or encapsulated form, the textiles will be enabled to have a more pleasant smell.
In a preferred embodiment of the invention, the preservative agents are added to the developed softener product so that said product may remain microbiologically stable. For this purpose, the preservative agents with different chemical structure may be employed. The use of at least one preservative agent selected from DMDM hydantoin, benzisothiazolinone, methylisothiazolinone and methylchloroisothiazolinone is possible. Other than those mentioned above, the antimicrobial raw materials having a cationic structure may also be added as preservative agent to the product. In case such raw materials are used, the antimicrobial property will also be conferred to the softener. For this purpose, at least one agent selected from didecyldimethylammonium chloride (DDAC), isopropyl alcohol or ethyl alcohol, or the mixtures of the same, may be used.
An alternative embodiment of the product developed within the scope of the invention comprises the cationic surfactant and the agent for conferring antistatic property at a ratio of 4.5-25% by weight. This embodiment preferably comprises the cationic surfactant at a ratio of 3-15% by weight and the agent for conferring antistatic property at a ratio of 1.5-7.5% by weight. Said embodiment additionally comprises 0.01-0.2% by weight antifoam agent. This embodiment of the invention comprises methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate as the cationic surfactant and a silicone emulsion as the agent for conferring antistatic property. Preferably, the weight percentage ratio of the cationic surfactant to the agent for conferring antistatic property is 2:1. More specifically, the weight percentage ratio of methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate to the silicone emulsion is 2:1. The pH value of the product is in the range of 2-4. A mixture of amino-modified silicone polyether copolymer and polyoxyethylene triglyceride is preferred as the silicone emulsion. This embodiment comprises methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate at a ratio of 3-15% by weight and the mixture of aminomodified silicone polyether copolymer and polyoxyethylene triglyceride at a ratio of 1.5- 7.5% by weight.
An alternative embodiment of the product developed within the scope of the invention comprises the cationic surfactant and the agent for conferring antistatic property at a ratio of 4-20% by weight. This embodiment preferably comprises the cationic surfactant at a ratio of 3-15% by weight and the agent for conferring antistatic property at a ratio of 1-5% by weight. Said embodiment additionally comprises 0.01-0.2% by weight antifoam agent. This embodiment of the invention comprises methyl bis[ethyl(tallowate)]-2- hydroxyethyl ammonium methyl sulfate as the cationic surfactant and a silicone emulsion as the agent for conferring antistatic property. Preferably, the weight percentage ratio of the cationic surfactant to the agent for conferring antistatic property is 3:1. More specifically, the weight percentage ratio of methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate to the silicone emulsion is 3:1. A mixture of amino-modified silicone polyether copolymer and polyoxyethylene triglyceride is preferred as the silicone emulsion. This embodiment comprises methyl bis[ethyl(tallowate)]-2-hydroxyethyl ammonium methyl sulfate at a ratio of 3-15% by weight and the mixture of aminomodified silicone polyether copolymer and polyoxyethylene triglyceride at a ratio of 1-5% by weight.
Dipalmitoylethyl hydroxyethylmonium methosulfate is of vegetable origin and has lower toxicity than the other cationic surfactants of the quaternary ester type.
