Abstract

The present disclosure relates to a filament ( 1,13,24 ) for printing a washing or cleaning agent product ( 12,28,31 ), comprising a filament matrix and at least one washing or cleaning agent component bound in the filament matrix, the filament matrix is formed, at least essentially, by at least one water-soluble plastic and the at least one washing or cleaning agent component is received in the filament matrix.

First claim

The invention claimed is:

1. A filament for printing a washing or cleaning agent product, comprising a filament matrix and at least one washing or cleaning agent component incorporated in the filament matrix, wherein the filament matrix is formed at least substantially by at least one water-soluble plastic material that forms a continuous phase throughout the filament matrix and wherein the at least one washing or cleaning agent component is absorbed in the filament matrix as a homogeneously dispersed and continuous phase, wherein the at least one washing or cleaning agent component includes one or more cobuilders selected from the group of oxydisuccinates, derivatives of disuccinates, ethylenediamine disuccinate, acetylated hydroxycarboxylic acids or salts thereof, and wherein the one or more cobuilders are present in an amount of from about 3 to about 15 wt. %, based on the total weight of the at least one washing or cleaning agent.

2. The filament according to claim 1 , wherein the filament has a diameter of between from about 0.1 millimeters (mm) and about 5 mm, and in that the filament has a length of at least about 5 meters (m).

3. The filament according to claim 1 , wherein the at least one water-soluble plastic material is a thermoplastic plastic material comprising a polyvinyl alcohol.

4. A filament for printing a washing or cleaning agent product, comprising a filament matrix and at least one washing or cleaning agent component incorporated in the filament matrix, wherein the filament matrix is formed at least substantially by at least one water-soluble plastic material that forms a continuous phase throughout the filament matrix and wherein the at least one washing or cleaning agent component is absorbed in the filament matrix as a homogeneously dispersed and continuous phase, wherein the at least one washing or cleaning agent component is one or more components selected from the group of surfactants, alkalis, builders, graying inhibitors, optical brighteners, hueing dyes, enzymes, bleaching agents, photobleaching agents, photocatalysts, soil release polymers, fillers, plasticizers, fragrances, anti-odor substances, zinc ricinoleates, dyes, nourishing agents, acids, starches, isomalt, sugar, cellulose, cellulose derivatives, carboxymethyl cellulose, polyetherimide, silicone derivatives, or polymethylimines, and wherein the at least one washing or cleaning agent component includes one or more of the builders including amorphous sodium silicate(s) having an Na 2 O:SiO 2 modulus of from about 1:2 to about 1:3.3.

5. A method for producing a filament comprising:
heating at least one water-soluble plastic material and at least one washing or cleaning agent component, in an extruder;
discharging from at least one nozzle of the extruder the at least one water-soluble plastic material and the at least one washing or cleaning agent component together in one strand as an extrudate; and
cooling the extrudate after discharging from the at least one nozzle to produce the filament, wherein the filament comprises a filament matrix and the at least one washing or cleaning agent component incorporated in the filament matrix, wherein the filament matrix is formed at least substantially by the at least one water-soluble plastic material that forms a continuous phase throughout the filament matrix and wherein the at least one washing or cleaning agent component is absorbed in the filament matrix as a homogeneously dispersed and continuous phase, and wherein the at least one washing or cleaning agent component includes one or more cobuilders selected from the group of oxydisuccinates, derivatives of disuccinates, ethylenediamine disuccinate, acetylated hydroxycarboxylic acids or salts thereof, and wherein the one or more cobuilders are present in an amount of from about 3 to about 15 wt. %, based on the total weight of the at least one washing or cleaning agent.

6. The method for producing a filament according to claim 5 , wherein cooling the extrudate comprises cooling the extrudate using at least one gas.

7. The method of claim 5 further comprising: printing a washing or cleaning agent product with the filament in a 3D printer.

8. The method according to claim 7 , wherein printing the washing or cleaning agent product comprises printing the washing or cleaning agent product in the form of a tablet, a strip, a film, a honeycomb structure or a sphere.

9. The method according to claim 7 , wherein printing the washing or cleaning agent product comprises printing the washing or cleaning agent product in particular different portions from different filaments and wherein, at least one inner portion of the washing or cleaning agent product is printed from at least one filament and at least one outer portion that surrounds the inner portion is printed from at least one other filament.

10. The method according to claim 7 , wherein printing the washing or cleaning agent product comprises printing the washing or cleaning agent product with a print template using the filament, wherein the print template comprises information relating to the gradual application of at least one material to the three-dimensional washing or cleaning agent product.

11. The method according to claim 9 , wherein printing the washing or cleaning agent product comprises printing the washing or cleaning agent product wherein the outer portion completely surrounds the inner portion.

12. The filament according to claim 3 , wherein the polyvinyl alcohol is partially saponified having a proportion of polyvinyl acetate present in an amount of less than about 30 wt. % of the polyvinyl alcohol.

13. The filament according to claim 12 , wherein the polyvinyl alcohol is cold-water-soluble having the proportion of polyvinyl acetate present in an amount of up to about 12 wt. % based on the weight of the polyvinyl alcohol.

14. The filament according to claim 12 , wherein the polyvinyl alcohol is hot-water solubility having the proportion of polyvinyl acetate present in an amount of up to about 1 wt. % based on the weight of the polyvinyl alcohol.

15. The filament according to claim 4 , wherein the at least one washing or cleaning agent component includes one or more anionic surfactants selected from the group alkylbenzene sulfonates, alkylether sulfates or soaps, wherein a total amount of the one or more anionic surfactants are present in an amount of from about 5 to about 50 wt. % based on the total weight of the at least one washing or cleaning agent.
