Abstract
The invention discloses a method for producing a super-flexible spherical three-dimensional hollow composite fiber. The method for producing the super-flexible spherical three-dimensional hollow composite fiber comprises the steps that (a) PET and PTT are adopted to serve as raw materials and are dried in a rotary drum; (b) melt is made from the dried raw materials through double-screw melting with the ratio of PET to PTT being 7:3; (c) double-component parallel filaments are formed through extrusion and combination under the action of a screw extruder, and cooling forming is achieved through circulating air; (d) the cured filaments are wound through a winding machine and are bundled; (e) drawing is conducted three times, wherein generally, the overall drawing ratio ranges from about 3.8 to about 4; (f) the positive pressure can not too high and the negative pressure is zero when the bundled filaments pass through a coiling machine; (g) cutting-off is achieved through a cutting-off machine, then the bundled filaments enter a shaping machine to be dried and shaped; (h) the filaments are packaged and then sent to a storehouse through circulating air. The method for producing the super-flexible spherical three-dimensional hollow composite fiber has the advantages that fibers prepared with the method are light and soft and are coiled naturally, balling is fluffy and smooth, and the fibers are novel ideal packing for warming clothes.
Description
Technical field
The present invention relates to a kind of fiber, specifically, relate to the production method of the three-dimensional hollow composite fiber of a kind of super soft ball-type.
Background technology
The current thick and heavy problem such as too fat to move of down jackets product ubiquity, not only affects attractive in appearancely, also people's activity in production is produced to certain impact.Develop a kind of can keep warm the light down jackets stuffing of weight again, become one of research topic of textile raw material.My company has overcome technical barrier, successfully develops light warming new packing.
Summary of the invention
The production method that the object of this invention is to provide the three-dimensional hollow composite fiber of a kind of super soft ball-type, the fiber quality that this kind of method prepared is slim and graceful, soft, curling nature, balling-up is fluffy smooth, is desirable insulation garment new packing.
The technical solution used in the present invention is:
The production method of the three-dimensional hollow composite fiber of super soft ball-type, its technique is as follows:
A, adopt two kinds of raw material PET and PTT, in rotary drum, be dried respectively, when dry strictly by temperature first low rear high order carry out, first 60 ℃, 80 ℃, 120 ℃, 135 ℃.Moisture being controlled at below 50ppm;
B, dried raw material is prepared to melt by twin-screw melting, on proportional quantity, press PET: PET=7:3 not equal portions process, in temperature, PTT adopts 260 ℃;
C, under the active force of screw extruder, by special spinning pack and measuring pump, extrusion cladding forms two component parallel silks, and by ring wind cooling forming;
D, by up-coiler, the strand after solidifying is reeled and boundling, in boundling process, to strand, oils, guarantee tow phozy, without static;
In e, drafting process, adopt three road drawing-offs, always lead more evenly than adjusting, can not destroy nature curling.Be generally total stretch ratio in 3.8-4 left and right;
F, when the crimping machine, main pressure can not be too high, 1.5KG left and right, is pressed and be should be zero, guarantee tow by time natural, can not be squeezed, in order to avoid destroy its feel;
G, by cutting machine, cut off, then enter setting machine and carry out drying and shaping, setting temperature can not be high, in order to avoid the contraction of being heated causes quality to baffle, is generally between 60 ℃-120 ℃;
H, by circulated air, carry packaging and warehousing.
Advantage of the present invention is: the fiber quality that this kind of method prepared is slim and graceful, soft, curling nature, and balling-up is fluffy smooth, is desirable insulation garment new packing.
The specific embodiment

D, by up-coiler, the strand after solidifying is reeled and boundling, in boundling process, to strand, oils, guarantee tow phozy, without static;
In e, drafting process, adopt three road drawing-offs, always lead more evenly than adjusting, can not destroy nature curling.Be generally total stretch ratio in 3.9 left and right;
F, when the crimping machine, main pressure can not be too high, 1.5KG left and right, is pressed and be should be zero, guarantee tow by time natural, can not be squeezed, in order to avoid destroy its feel;
G, by cutting machine, cut off, then enter setting machine and carry out drying and shaping, setting temperature can not be high, in order to avoid the contraction of being heated causes quality to baffle, is generally between 60 ℃-120 ℃;
H, by circulated air, carry packaging and warehousing.
