Abstract

A single-dose laundry detergent packet includes a solid laundry detergent or cleaning agents, and a water-soluble wrapping that completely surrounds the solid laundry detergent or cleaning agent, wherein the exterior of the water-soluble wrapping is at least partially covered with a fiber material. The present invention further relates to a method for the production of a single-dose laundry detergent packet, and washing methods using these single-dose laundry detergent packets.

Claims (24)

1 . A single-dose laundry detergent packet comprising:

a laundry detergent or cleaning agent;

a water-soluble wrapping that completely surrounds the laundry detergent or cleaning agent; and

individual fibers adhesively bonded over the exterior of the water-soluble wrapping that overlaps with the laundry detergent or cleaning agent using a thermoplastic adhesive,

wherein the individual fibers are adhesively bonded over from 30% to 45% of the exterior of the water-soluble wrapping.

2 . The single-dose laundry detergent packet of claim 1 , wherein the single-dose laundry detergent packet is in the form of a bag.

3 . The single-dose laundry detergent packet of claim 1 , wherein the individual fibers are water-soluble fibers.

4 . The single-dose laundry detergent packet of claim 1 , wherein the individual fibers are printed.

5 . The single-dose laundry detergent packet of claim 1 , wherein the water-soluble wrapping comprises a water-soluble film.

6 . A method for textile care or textile cleaning, the method comprising introducing the single-dose laundry detergent packet of claim 1 into a dispensing drawer or a washing drum of a textile washing machine.
