Claim Text:
1. A method of entangling a first yarn into a moving main yarn, comprising: aligning the first yarn substantially parallel to the main yarn, and subsequently directing a fluid jet onto the first yarn for separating filaments and/or groups of filaments in the first yarn from each other and to intermingle filaments and/or groups of filaments of the first yarn with filaments and/or groups of filaments of the main yarn to form mechanical friction points between filaments and/or groups of filaments from the first yarn and the main yarn, thereby entangling the first yarn into the moving main yarn, wherein the fluid jet is directed onto the first yarn at least at sonic speed, and a speed of the main yarn before and after the entangling is essentially the same.
