Description

Cooling mechanism for small-hole-number ultra-coarse denier monofilaments Technical Field The specification relates to the field of spinning technology, and in particular relates to a cooling mechanism for a small-hole-number ultra-large-denier monofilament. Background In the current civil chemical fiber filaments, for ultra-coarse denier monofilaments FDY (full DRAWN YARN ‌, also called ‌ Fully drawn filaments ‌) with small hole number of terylene, the single filament fineness is generally more than 16D, such as 200D/12f, and the single filament fineness=200/12= 16.6,12 fiber monofilaments are compounded into filaments with 200D fineness, because of the special rigidity and toughness, the filaments are generally used for making home textile fabrics, box wrapping fabrics, tent fabrics and the like, and if special-shaped cross sections (such as flat, wavy flat and the like) are added, the filaments can also be used for making bristle varieties in fluff types, and have considerable product overflow price. In principle, the ultra-coarse FDY variety of the monofilament is not easy to cool uniformly, the distance of a traditional circular blowing cooling area is short, generally only about 50cm, and the common specification of civil polyester fiber is cooled sufficiently, such as 30D/24f, 50D/72f and the like, and the single fiber is about 1D. For the special variety with single fiber exceeding 16D, the required cooling area distance is long, and the traditional circular blowing cooling equipment and process cannot achieve the purpose of uniform cooling. The purpose of cooling by side blowing air can be achieved, but the purpose of uniformly cooling the thick terylene FDY of the monofilament cannot be achieved by a single side blowing mode, so that the single side of the surface air is cooled quickly, the cooling on the leeside is slow, the cooling stress difference can occur, and the internal tension of the silk is unstable.
