(5) give the two-sided interpolation finish of spinning;
(6) multistage hot-stretch and roller stretching are carried out in spinning;
(7) spinning is handled by High Temperature High Pressure distortion carton deformed;
(8) spinning after the processing is by the quenching air cooling;
(9) cool off the spinning that finishes and go out the network joint through Network device strand network;
(10) spinning is rolled into tube.
The PTT chip drying temperature in described (1) step is 130 ℃-139 ℃, and the PTT section in described (2) step is 245 ℃-269 ℃ in extruder heat fused temperature.
The lateral blowing temperature in described (4) step is 16 ℃-18 ℃, wind speed: 0.6 m/s-1.0m/s, rheumatism: 76%-85%.
Described (5) step is added the oil agent rate of finish: 0.6-1.0% to spinning, described (6) goes on foot the roller draft temperature to spinning: 70-85 ℃, and draw ratio: 4.5-5.0.
The temperature of described (7) step distortion case heating spinning is 150 ℃-168 ℃, described (8) step is 15 ℃-18 ℃ with quenching air cooling spinning temperature, and wind speed is greater than 1.0m/s.
Number: the 25-45/rice of network joint that described (9) step strand network goes out.
Compared with prior art, the ptt fiber of a kind of carpet of the present invention, similar and the triangle of its cross section structure shape, so have stronger stability, and every limit is the arc lines, has more stronger rebound performance, and brightness height, bulk good, easy dyeing, soft, cost is low, development potentiality is huge, has a extensive future.
Description of drawings
Fig. 1 is a schematic cross-section of the present invention;
Wherein, 1-left side camber line, the right camber line of 2-.
The specific embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the ptt fiber of a kind of carpet of the present invention is characterized in that: the ptt fiber cross section of described a kind of carpet is a trilobal.
Described trilobal is an overall structure that is made of three identical classes, half leaf framework, described class half leaf framework comprises left camber line 1 and right camber line 2, the radian of left side camber line 1 and right camber line 2 is identical with length, and the top of left camber line 1 links to each other with the top of right camber line 2.
For the stability that guarantees that it is stronger, described three classes half leaf framework is necessary for identical, so just has stronger support performance; And the radian of left camber line 1 and right camber line 2 is identical with length, is an easier pressurized of camber line fiber less relatively for fear of radian or that length is relatively short, causes discontinuity.
The top of distance and left camber line 1 or right camber line 2 is 1:0.8 to 1:1.2 to terminal air line distance ratio between described left camber line 1 end and right camber line 2 ends.
In this ratio range, the long more then resilience of distance between left camber line 1 end and right camber line 2 ends is good more, and the long more then stability of distance is good more between the camber line two-end-point, produces as required.
