Abstract
The invention relates to a method of treating a fabric. It particularly relates to a method of treating a fabric with a rinse product that reduce soil pickup and further ensures that the fabric is cleaner after the subsequent wash. It is thus, an object of the present invention to provide a method of treating a fabric to render the fabrics relatively more hydrophobic and especially to provide a method of treating a fabric during the rinse stage of the fabric cleaning process that reduces subsequent soiling of the fabric during use by the consumer. It has been found that contacting the fabric with a neutral aqueous solution, comprising a water- soluble zinc compound, a deposition aid selected from the group consisting of an amine compound or an amino acid and a soap before drying said fabric, provides the soil repellence to the fabric.
Description
M ETODO TO TREAT A N GENDER
Technical field
The invention relates to a method for treating a genre. : In particular, it relates to a method for treating a fabric with a rinse product that reduces the uptake of dirt and also ensures that the fabric is cleaner after subsequent washing.
Background and previous technology
The genera have been traditionally cleaned using detergent formulations. Detergent formulations generally comprise surfactants and formers. It is believed that surfactants work by reducing the surface tension of water, thus ensuring preferential division of dirt from the surface of the fabric into the wash water.It is believed that the formers act by reducing the hardness of water, thereby ensuring Efficient use of surfactants Various other benefit agents have been included in detergent formulations, eg perfumes, optical brighteners, electrolytes, free-flowing agents, soil release polymers (SRP), anti-redeposition agents (ARD) , enzymes, bleaches, dyes and preservatives.Of the above, the SRP and ARD agents are added to the detergent formulation to intensify the cleaning by acting on the dirt.
The redeposition of dirt is a phenomenon that reduces effective cleaning as compared to what the surfactants can theoretically provide. The redeposition of dirt is a problem for a long time that detergent formulators have struggled to solve. The redeposition is defined as the division of dirt removed from dirty clothes back into so dirty / clean clothes during the washing process. This problem is illustrated by showing the gradual graying of a fresh white garment that has never been worn or worn but only through the wash load. This shows that one of the primary reasons for loss of whiteness or grayness is due to redeposition of dirt. Usually; the loss of whiteness due to redeposition is not evident in a simple wash cycle, but manifests itself gradually after multiple cycles. Some examples of common anti-redeposition polymers are carboxy methyl cellulose sodium (SCMC), Sokalan CP5 or CP7, polyaspartic acid, Alcosperse and Narlex H1200.
SRP agents act by mechanisms, which make dirt easier to release from the surface of the fabric.
Various agents have been used to provide soil release benefits: for example, starches, modified starches, carboxymethyl cellulose, polyethylene glycols, maleic anhydride copolymers, and anionic surfactants provide enhanced soil release when they are sprayed or mulched on polyamide polyester fabrics. before soiled In addition, the acrylate-based copolymers have been successfully deposited on acid rinse or rinsing fabrics containing relatively high concentrations of polyvalent metal ions or water soluble amine salts to give temporary dirt release finishes. The fluorinated dirt release agents can also be applied in a rinse mode. Polyester-based co-poly (ethylene terephthalate) (polyoxyethylene terephthalate) (PET-POET dirt release agents) have been particularly used for polyester fabrics. These polymers were marketed under the trade names of Permalose, Ciruelo, PTG, Ciruelo PTN and Milease T.:
The above agents are generally included, in detergent formulations, which are added in the wash cycle of the cleaning process. These cleaning formulations do not help much to reduce subsequent post-wash fouling of the fabrics. The present inventors have determined during the course of their extensive research in this area that one of the main ways in which soiling of soils can be kept cleaner is by ensuring that the uptake of dirt by the post-wash fabric is minimized. The present inventors then invented a step hitherto not known to treat the fabric during the rinsing step with a zinc compound which is capable of giving the above benefits. Without wishing to link to a theory, the inventors believe that the present invention makes the surface of the fabric more hydrophobic, thereby ensuring the benefits of dirt repellency to the consumer goods. For the knowledge of the inventors, some documents have been published, which describe methods to make substrates more hydrophobic. GB 916,665 relates to a process and material for the antimicrobial treatment of a / o genera and describes compositions comprising a zinc complex in combination with amine compounds, such as urea and detergents.
WO 2004/003121 relates to disinfection compositions comprising chelating metal complexes for use in a / o pools, spas, laundry soaps, paint or surface coating additive, fiber preservative, plastic or wood and as carpet sanitizer or hard surface. '
Tang et al in Colloids and Surfaces A: Physicochem. Eng. Aspects 296 (2007) 92-96 describe a process for preparing uniform nanobariras of hydrophobic zinc oxide via a one step process through the precipitation transformation reaction in aqueous solution of zinc sulfate, sodium carbonate and hydroxide of sodium with sodium oleate.
Badre et al. in Nanotechnology 18 (2007) 365705 (4 pp) describe the preparation of superhydrophobic zinc oxide nanowire fixation films by initiating with zinc chloride by adjusting an electrochemical method followed by surface modification with stearic acid.
The present inventors have determined that the process described by the aforementioned technique is not suitable for daily application in the homes to treat consumer goods in terms of fulfilling the desired technical efficiency, safety and convenience for the consumer and cost.
Thus, one of the objects of the present invention is to provide a method for treating a genus to make the genera relatively more hydrophobic.
Another object of the present invention is to provide a method for treating a fabric during the rinsing step of the fabric cleaning process which reduces subsequent soiling of the fabric during use by the consumer.
