    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The curly monofilament yarn is generally manufactured from a straight monofilament yarn that is subjected to one or more heat treatments. This treatment may take place as from the extrusion of the yarn and/or during the processing step and/or on the finished carpet. Preferably, the final curling and crimping is obtained after a heat treatment during the coating of the tuft fabric with a stabilizing agent, such as for example latex, as a result of which also the tufts become firmly attached in the tuft fabric. In its finished form the support fabric comprises a laminate of a tuft fabric with an additional layer of a stabilizing agent, preferably a latex, applied onto it.
  • According to present the invention, the manufacturing of curly monofilament yarn by means of a heat treatment can be performed in 3 different ways, i.e. by means of a heat treatment of the monofilament yarn directly after extrusion and before the tufting process, by means of a heat treatment during the application of the adhesion material (latex) on the tuft fabric, or by means of a combination of both aforementioned heat treatments. In a preferred embodiment the straight monofilament yarn is subjected to a first heat treatment which takes place before the tufting process such that an initial curling arises. Subsequently, the straight and partly curly monofilament yarn is tufted in line on a tuft fabric, after which a latex backing is applied to the back of aforementioned tuft fabric by means of a second heat treatment. The application of the latex backing and the associated heat treatment completes on the one hand the curling and ensures on the other hand an optimum fixing of the tufts in the tuft fabric. After aforementioned heat treatment(s), the curly monofilament has a shrinkage of at least 60% and more preferably of at least 50%. Therefore, the rest height of the curly yarn ranges between ⅕ to ⅗, preferably ⅓ to ⅗ and most preferably approximately ½ of the length of the straight monofilament yarn in the tuft. This height ratio on the support fabric ensures that a good elasticity and bonding strength to the artificial turf are obtained such that an infill becomes superfluous.
  • Both aforementioned monofilament yarns are subsequently twined together to form one yarn and this with a speed of approximately 30 turns per running meter wherein the curly monofilament yarn is nested around the straight monofilament yarn. The finally obtained composed yarn has a yarn number which usually ranges between 10,000 dtex and 20,000 dtex, preferably between 12,000 and 16,000, more preferably between 13,000 and 15,000 and is most preferably approximately 14,000 dtex.
  • Preferably, the filaments in a tuft all have the same length between 3 and 5 cm, more preferably between 3.5 cm and 4.5 cm and most preferably approximately between 3.7 and 3.9 cm. The curly filaments in their curly state have a length ranging between 40 and 60% with respect to the initial length. In general, the shrinkage is obtained by a heat treatment.
  • The invention is further illustrated by means of the examples below which illustrate some preferred embodiments of the invention.
    • Example 1
  • The compound yarn comprises 8 filaments curly monofilament yarn of polyamide 6 (nylon) with a compound dtex value of 6000 (8 filaments of each 750 dtex per filament) with a width of 0.9 mm, a thickness of 140 μm and a height of 38 mm in elongated form and a height of approximately 24 mm in curly form with 8 filaments straight monofilament (diamond structure) with a dtex value of 8000, a width of 0.9 mm and also a thickness of 140 μm. These yarns are twined together and subsequently this composed yarn is linearly tufted with approximately 140 stitches per running meter with a needle distance of 5/16″, and a pile height of 38 mm such that a pile weight was obtained of approximately 2200 g/m2. The support material comprises a polypropylene tuft fabric which is UV-stabilised with a specific weight of approximately 164 g/m2 provided with a latex backing with 1000 g/m2.
  • The obtained artificial turf have the following properties:
  •
    Colour stability Scale 7 (DIN 54004)
    UV-Stability >6,000 u (DIN 53387)
    Water permeability 6.10−4 m/sec
