A method is disclosed for fabricating a ribbon yarn, the method including: spreading the yarn such that not more than five filaments are lying over one another, fixing the yarn by forming a matrix of one or more fixatives, winding the fixed yarn, wherein the fixative or fixatives are selected from a group consisting of copolyamides, copolyesters and silicones and also mixtures or blends thereof. Also described is the ribbon yarn and the application of the ribbon yarns for airbag fabrics, as a tire reinforcement and in textile construction.

Ribbon yarn

A fiber composite having one or more layers of reinforcing fibers or filaments, that contains one or more layers of ribbon yarns brought into contact with it, as well as a method for its production.

Fiber composite and method for its manufacture

The present invention relates to a process for producing a polyphenylene sulfide multifilament yarn, a polyphenylene sulfide multifilament yarn and the use of a polyphenylene sulfide multifilament yarn. The process for producing a polyphenylene sulfide multifilament yarn is characterized in that only after time period between 0.1 sec and 0.3 sec after leaving the spinneret the filaments of the spun yarn are subjected to an active cooling stage. The Polyphenylene sulfide multifilament yarn having a filament linear density of 5 dtex to 30 dtex, an overall linear density of 500 dtex to 2500 dtex, a breaking tenacity in the range of 50 cN/tex to 80 cN/tex and an elongation at break of 8% to 16% for a yarn with a breaking tenacity in the range of 60 cN/tex to 80 cN/tex and an elongation at break of 16% to 30% for a yarn with a breaking tenacity in the range of 50 cN/tex to 60 cN/tex.

Process for producing polyphenylene sulfide filament yarns

A method for coating yarn is proposed, including steps in which the yarn is first placed in contact with a dispersion of the coating agent in a dispersing agent or with the coating agent in melted form, optionally excess dispersion or melt is scraped back off the yarn, and then the coating is formed on the yarn, where in the case of the dispersion this occurs by means of at least partially removing the dispersing agent by heating, and the yarn thus coated is then cooled down and wound, which is distinguished by the fact that the coated yarn undergoes additional cooling before winding.
