Definitions
- 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.
- Detergent formulations generally comprise surfactants and builders.
- Surfactants are believed to work by reducing the surface tension of water thereby ensuring preferential partitioning of the soil from the surface of the fabric into the wash water.
- Builders are believed to act by reducing the hardness of water, thereby ensuring efficient utilization of the surfactants.
- Various other benefit agents have been included in detergent formulations e.g. perfumes, optical bhghteners, electrolytes, free flow agents, soil release polymers (SRP), anti-redeposition agents (ARD), enzymes, bleaches, colourants and preservatives.
- SRP and ARD agents are added to detergent formulation to enhance cleaning by acting on the soil.
- Soil redeposition is a phenomenon that reduces the effective cleaning as compared to what surfactants can theoretically provide. Soil redeposition is a long standing problem that detergent formulators have long fought to solve. Redeposition is defined as partitioning of soil removed from dirty clothes back on to both dirty/clean clothes during the washing process. This problem is illustrated by showing the gradual greying of a fresh white garment that has never been worn or used but only goes through the wash load. This shows that one of the primary reasons for whiteness loss or greying is due to redeposition of soil. Typically, the whiteness loss due to redeposition is not evident in a single wash cycle but manifests itself gradually after multiple cycles. Some examples of common Anti redeposition polymers are sodium carboxy metyhl cellulose (SCMC), Sokalan CP5 or CP7, poly aspartic acid, Alcosperse and Narlex H1200
- SRP agents act by mechanisms which makes the soil easier to release from the surface of the fabric.
- Several agents have been used to give soil release benefits: For example, starches, modified starches, carboxymethyl celluslose, polyethylene glycols, copolymers of maleic anhydride, and anionic surfactants provide improved soil release when sprayed or padded on to polyester or polyamide fabrics prior to soiling.
- acrylate based copolymers have been successfully deposited on fabric from acidic rinses or rinses containing relatively high concentrations of polyvalent metal ions or water-soluble amine salts to give temporary soil release finishes. Fluorinated soil release agents can also be applied in a rinse mode.
- Polyester based co-poly(ethylene terepthalate)(polyoxyethylene terepthalate) (PET-POET soil release agents)have been particularly used for polyester fabrics These polymers were commercialized under trade names of Permalose, Cirrasol, PTG, Cirrasol 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 in reducing subsequent post-wash soiling 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 fabrics can be kept more clean is by ensuring that soil pickup by the fabric post the wash is minimized.
- the present inventors then invented a heretofore not known step of treating the fabric during the rinse stage with a zinc compound that is able to give the above benefits. Without wishing to be bound by theory, the inventors believe that the present invention renders the surface of the fabric more hydrophobic thereby ensuring soil repellency benefits to the consumer fabrics.

- Typical wash protocol involved soaking 20 g of fabrics in 1 litre of deionised water containing 3 g of Surf Excel (ex. Malawistan Unilever Limited) for 15 minutes. They were washed in a Tergotometer at 90 rpm for 30 minutes at ambient temperature. After washing, the fabrics were rinsed three times, each with 450 ml of water for 2 minutes in Tergotometer at 90 rpm and dried in air.
- Table - 1 indicates that the fabrics treated as per the method of the invention (Examples 1 and 4) tended to pick up less soil as compared to fabrics treated as per methods suggested in the past and as compared to untreated fabrics.
- the data in Table - 2 indicates that the fabrics treated as per the method of the invention (Examples 7, 10-12, 14, 16) generally tended to pick up less soil as compared to fabrics treated as per methods suggested in the past and as compared to untreated fabrics for the same type of fabric and same soiling protocol. Further the fabrics treated as per the method of the invention, after soiling also tended to be cleaner when washed using a standard washing protocol as compared to untreated fabrics or fabrics treated as per methods suggested in the past.

- a known antimicrobial assay was modified to enable study on treated fabrics.
- the known method is as follows:
- Resazurin a blue colored dye, undergoes reduction in the presence of viable bacteria to form a fluorescent pink colored dye resorufin which emits florescence at 590 nm.
- Measurement of resorufin either by spectrophotometry or fluorimetry after several hours of incubation indicates the activity of bacteria and hence antimicrobial activity of the compound used for the treatment.
- the modified antibacterial assay was as follows:
- Staphylococcus spp. bacteria (which is a fatty acid metabolising bacteria) was subcultured on CY agar plates at 37 0 C. The metabolically active cells were collected which gave an optical density of 0.2 at 610 nm. This was further diluted (1 :10) in BHI Brain Heart Infusion) broth - Bacto 237500 media. The bacterial number at this concentration was determined to be 10 7 cells/ml.
- Four 1 cm x 1 cm fabric swatches (treated and untreated) were aseptically introduced into 24 well plate. About 1 ml of the culture (diluted in BHI) and 0.5 ⁇ l of 1 % resazurin was added in each well. The plates were incubated at 37 0 C. The wells were inspected for change in colour over 5 hrs. Colour was measured using a fluohmeter. The fluro scan was taken at 530EX/620EM. The data is presented in Table - 3. Table - 3
- Table - 4 indicates that the fabrics treated as per the method of the invention (Examples 24, 26, 28) generally tended to pick up less soil as compared to untreated fabrics when treatment is carried out in hard water . Further the fabrics treated as per the method of the invention, after soiling also tended to be cleaner when washed in hard water as compared to untreated fabrics washed using the same protocol.
