Description
Technical field
The present invention relates to a kind of manufacturing approach of fabric of island-in-sea type bicomponent filament yarn and the composite spining module of use thereof.
Background technology
Islands-in-sea bicomponent fibre is a kind of polymer with the form of a plurality of superfine fentos (being referred to as the island) among another kind of polymer (being referred to as the sea).
The production of present fabric of island-in-sea type bicomponent filament yarn all is to adopt the island method of deciding, and is promptly passed through the fusion respectively of twin-screw composite spinning machine, is got into the fabric of island-in-sea type filament spinning component by two kinds of polymer, and island phase and marine facies converge ejection through path separately in the porch of spinneret orifice respectively; Form islands-in-sea type fibre; Its island phase and marine facies are continuous, equally distributed at the length direction of fiber, and the island number is fixed, generally more than 37 islands; It normally decides island component with PET or the conduct of PA6 raw material; Water-soluble polyester COPET is as extra large component, and the extra large component of the composite fibre of producing in this way and the ratio of island component are generally 30: 70 or 20: 80, and the content of island component is higher.
In this fabric of island-in-sea type spinnerets, the monofilament on 37 islands is that the high polymer melt thread by the ejection of 37 needle tubing groups is condensed into fibre, and needle tubing and needle plate adopt close-fitting to merge auxilliaryly with the Laser Welding reality needle tubing can not to be come off usually.If spinnerets is 200 holes; Corresponding is 200 needle tubing groups; Every group of 37 needle tubings (amounting to 7400 needle tubings) are corresponding with 200 groups every group 37 pod apertures (amounting to 7400 pod apertures) of deflector; Each needle tubing cooperates concentricity must have high accuracy could satisfy the requirement of spinning islands-in-sea type fibre very much with pod apertures, the island just can be evenly distributed on marine and adhesion, and machining accuracy height, the expense of therefore deciding needle tubing plate, deflector and spinnerets in the assembly of island are big; In the cleaning and assembling process of assembly since the needle tubing plate be prone to bump, yielding, maintenance cost is also high.The island number is many more, and the perforate of spinnerets is few more, and production capacity is low more, invests bigger.
Indefinite island method is produced islands-in-sea bicomponent fibre, and slices of caprone PA6 commonly used and low density polyethylene mix under uniform temperature and condition, through same screw extruder fusion, blend, again through measuring pump, filament spinning component ejection, forms the superfine fibre on indefinite island.Its island of islands-in-sea type fibre that this kind method is produced is mutually discontinuous, fixing, i.e. the length on island and be distributed in and have randomness in the certain limit, so this fiber only is applied in the production of staple fibre at present; The ratio of island phase component is lower in this kind production method; Generally about 50%, if reach 55% when above, the island irregular abnormal shape (king-sized island or island and island adhesion) will occur mutually; But because the production of this fiber employing is conventional filament spinning component; Production cost is low, and output is high, therefore on the microfiber synthetic leather base cloth, still has more widely and uses.
Summary of the invention
The present invention is intended to propose the production method that a kind of cross section is a ferris wheel type island bicomponent filament yarn.
The present invention is intended to propose a kind of employed composite spining module of production ferris wheel type island bicomponent filament yarn that is used for, and the fiber cross section that makes is as ferris wheel, and skin has a delineation island, all the other are the fabric of island-in-sea type bicomponent filament yarn on indefinite island.
