Definitions
- the field of the present invention relates to unit dose cleaning products.
- the field of the present invention relates to unit dose cleaning products prepared by nonwoven websheet.
- the field of the present invention relates to unit dose cleaning products prepared by nonwonen websheet made of hydrophobic polymer particularly of polyolefine based polymers.
- the field of the present invention relates to nonwoven fabric construction suitable for use as detergent pouch.
- the field of the present invention relates to unit dose cleaning products containing detergent compositions in solid particulate form.
- the field of the present invention relates to unit dose cleaning products containing detergent compositions for laundry or dishwashing or body cleansing.
- Detergents are pre-portioned in pouches as pouches have been known for a long time.
- the employment of detergent pouches attracts the attention of consumers since the need for measuring off the detergent quantity required for a washing program from detergent powder box was obviated.
- the pouch containing the detergent composition can be easily removed from the box involving plurality of such pouches and also, can be easily placed into the washing machines without any possible attendant spilling, dusting or inhaling of powder.
- the efficiency of cleaning operation as a result of precise dosing, avoiding of spills, wasteful overdosing and underdosing was improved accordingly.
- the users’ hands do not come into contact with detersive and potentially skin irritating constituents of the cleaning composition, which is particularly important for users having an allergic reaction to detergent constituents.
- the properties of the pouches have to be taken into consideration such as; the outer shells of the pouches have to be so dense to keep constituents enclosed.
- the material used for pouch construction must not be affected by the constituents and also, it has to be water permeable to enable the rapid leaching of the constituents by the wash water.
- the materials of outer shells, used in pouch formation must have high processability in filling and packaging machines. Additionally, the pouch material should be inexpensive for being preferred by the consumer. Pouches known in the art do not provide all these properties at the same time.
- the nonwoven websheet prepared from hydrophobic polymeric materials such as polyester or polyolefine preferably from polypropylene has a slow water penetration into the inside of the nonwoven pouch. This causes a retarded dissolution of the cleaning composition inside of the pouch and retarded exit from the inside. As a result, the cleaning process starts quite late and as the result of the slow release ends late, which is not desired due to waste of time and energy.
- the hydrophobic character of the nonwoven websheet fibers being polyolefine, polypropylene hinders water entry with a proper rate and speed, which makes the washing process unpractical and time consuming.
- US5110640A offering a different approach for the complete transfer of ingredients of detergent pouch into the wash water.
- This application employs the water sensitive fibers which are formed into a web or sheet. These web or sheets are used to form a detergent pouch wherein when these pouch is wetted, the fibers loose a predetermined crimp. The length of fibers between bonding sites increases and the interstices enlarge so that the particles of detergent composition contained within the pouch can then pass through the wash liquor.
- this application offers an alternative solution for the complete transfer of the bag constituents, it suffers from insufficient increase of fiber lengths between bonding sites and insufficient enlargement of interstices.
- bonding with crimped fiber is not mechanically robust enough to keep the particulate ingredients safely inside the pouch, by mechanical stress enlargement of the pores and spilling of the ingredients is possible.
- the present invention overcomes the above mentioned drawbacks by providing a unit dose cleaning product having an outer shell prepared by water permeable but water insoluble materials having hydrophilic spin finish layer enabling facile and rapid intrusion of water.
- the present invention overcomes above mentioned drawbacks by providing a unit dose cleaning product having an outer shell prepared by water permeable but water insoluble materials such as nonwoven websheet having hydrophilic spin finish treatment.
- a nonwoven websheet of water permeable but water insoluble and hydrophobic material having hydrophilic spin finish treatment prepared by polyethylene or polypropylene as an outer shell is provided and then manufactured into unit dose cleaning product which is filled with particulate cleaning composition.
- FIG. 1a Top wiev of a unit dose cleaning product of the present invention prepared according to Example 5.
- FIG. 1b Side wiev of a unit dose cleaning product of the present invention prepared according to Example 5.
- FIG. 2 Layers of SSMMS nonwoven websheet according to Example 1.
- FIG. 3. A picture of a unit dose cleaning product of the present invention prepared according to Example 5.
- the outer shell of the water permeable but water insoluble pouch of the present invention can be prepared from a nonwoven websheet.
- This nonwoven websheet is made from fibers or filaments of hydrophobic character such as polyolefin, polypropylene, polyethyleneteraphthalate, polyester, PVC, polyethylene.
- Nonwoven webs used in the present invention can be made by spunmelt process which encompasses two processes such as spunbond and meltblown or the combinations of both.
- Spunbonding is based on extrusion of multiplicity of continuous thermoplastic polymer strands thorough a multiciplicity of die orifices in a downward direction onto a moving surface. These extruded strands are collected in randomly distributed mode which are then bonded together to provide integrity to the resultant non-woven web.
- the nonwoven web prepared by spunbonding has high strength, high porosity and good abrasion resistance.
- Meltblowing differs from spunboding. In meltblowing, extruded strands are broken up and then, before collecting onto a moving surface, these extruded strains are dispersed into individual fibers. The fibers first cooled by air then bonded together to obtain structural integrity.
- the nonwoven websheet of the present invention comprises; A unit dose cleaning product having an outer shell made of a nonwoven websheet material having an exterior surface side and interior surface side containing cleaning composition of solid particulate material comprising;
- At least one layer of spunbond (S) material located on the exterior surface side of the outer shell,
- At least one layer of spunbond (S) material located on the interior surface side of the outer shell,
- At least one layer of meltblown (M) material located between said spunbond materials (S) of the exterior and interior side of the outer shell.
- said outer shell comprises a hydrophilic spin finish treatment made with a hydrophilic spin finish composition.
- the meltblown layer of the present invention for polypropylene fiber material comprises fibers with diameter in the range of between 1.0- 3.0 micron, preferably 1.2- 2.0 micron.
- the meltblown fiber diameter below said values are not strong enough to resist mechanical stress and may broke; too high of diameter may fail to build a strong mesh and cause spilling.
- Spunbond layers of the construction improve the strength and softness of the web, giving a fabric-like appearance while providing large pores.
- the inclusion of the meltblown layers makes the web more compact and reduces the pore size of the web wherein meltblown layers act as a barrier to prevent outward passage of the composition.
- the non-woven websheet construction of the present invention has sufficient wet strength which enables the product to survive during washing process without disintegrating.
- the nonwoven websheet of the present invention has the weight ratio of said meltblown (M) material to the nonwoven websheet material of at most 15%, preferably 10%.
- the nonwoven websheet has an outer surface side and an other outer surface side, whereas other surface side is positioned on the opposite surface side of the outer shell nonwoven websheet.
- the nonwoven unit dose product of the present invention comprised of polypropylene fibers weighs about 10 to 100 gsm, preferably 15 to 70 gsm. Within these ranges the nonwoven websheet keeps the ingredients from spilling and has the necessary strength to withstand to mechanical stresses. Too high of nonwoven websheet weights cause delayed release of ingredients and economically not feasible due to failing to contribute to effectiveness.
- gsm stands for gram per square meter; g/m2.
- the hydrophilicity of the nonwoven websheet is provided by using spin finish technology.
- the method applied for providing the feature of enhanced hydrophilicity is providing the spin finish treatment.
- the hydrophilic spin finish treatment of the present invention is accomplished with a spin finish treatment composition which comprises mainly mixtures of cationic surfactants in an aqueous emulsion or a solid dispersion.

- Nitrogen atom of said quaternary ammonium compound comprises alkyl carboxylated groups, alkyl hydroxyethyl, polyglycol residue and as counterion methylsulfate, acetate, phosphonate, Chloride; said polydimethyldisiloxanes have similar counterions.
- Said quaternary ammonium compound may be ditallow dimethyl ammonium compound, its chloride salt.
- Said nonionic surfactant may be fatty acid ester or ether such as fatty acid polyethylene glycol ester, fatty acid polyethylene glycol ester methyl ether.
- Said siloxane compounds may be alkoxylated polysiloxanes, ether polydimethyl siloxanes.
- Said composition may contain polyoxyalkylene modified dimethyl siloxanes, nonionic surfactants, quaternary ammonium salts.
- the composition can contain at least one cohesion agent, lubricant, corrosion protecting agent, and emulsifier. These may be fatty acid ethoxylate as lubricant and emulsifier and ricinol ethoxylate as cohesion agent.
- the hydrophilic spin finish treatment composition of the present invention is applied in quantities from 0.2-5.0% relative to nonwoven websheet weight, preferably in the range of 0.3- 2.0 by weight depending on the hydrophilicity required. Said applied weight is the dry matter remaining after application of aqueous spin finish treatment composition and subsequent drying.
- the aqueous emulsion or solid dispersion has an active content of upto 20% by weight, whereas to avoid high viscosity concentrations, less than 5% content is preferred. With the active content hydrophilicity contributing agents in the composition is meant.
- the aqueous composition of the present invention is prepared by mixing of the components in water and homogenizing by a thorough stirring with subsequent diluting with water to form aqueous dispersion or emulsion of the composition. This composition is used for hydrophilic finishing of the nonwoven websheet.
- the spinfinish composition may be applied by contacting nonwoven websheet with the aqueous composition, thus imparting hydrophilic properties to hydrophobic nonwoven websheet. Obtained treated nonwoven websheet conveys water quickly into the pouch where the cleaning composition is found.
- the obtained, with hydrophilic finishing treated nonwoven websheet is used to prepare a unit dose cleaning product by filling the nonwoven websheet with cleaning composition and welding the edges of the nonwoven websheet to form a pouch.
- Unit dose products obtained with this method are allowing water entry to the inside of the pouch in a fast manner contrary to the pouchs having nonwoven websheets which are not hydrophilic spin finish treated.
