The straightening out effect of leading hooked fibre；Two and and three and back area draft gradually reduce, stretched in favor of further increasing the fiber of ripe bar
Straight degree；
Running operation will keep draft area cleaning, be uniformly mixed, and 4.0%, relative humidity is controlled 75% for drawn sliver regularity CV control；
(6), Roving Frames
The process is using longitude and latitude weaving A186F fly frame, and Roving Frames are using " big gauge, light quantitatively, again pressurization, small back zone are led
Stretch " technological principle, so that thick Yarn Evenness is uniform；Since terylene, china-hemp fibers, bamboo pulp fiber surface are smooth, coherent is poor,
It is also easy to produce misdraft, causes rove evenness fault, thus roving twist factor need to be fitted in the case where guaranteeing spun yarn not harmful drafting
When grasp bigger than normal；Relative humidity is 65%；Main technologic parameters: roller gauge 14mm × 28mm × 38mm, nip gauge 5.5mm,
Spindle revolving speed 800r/min, regular roving feeding 6.4g/10m, design twist factor 76,5.8 times of total draft multiple, first break draft multiple 1.19
Times；
(7), spinning process
The process combines bamboo pulp because of the yarn category knitting yarn of exploitation using Ma Zuoli (East Platform) DTM129 type spinning frame
Fiber, china-hemp fibers feature, using the technological principle of " big gauge is again pressurizeed, small nip gauge, small back area draft ", back zone is led
Stretch multiple grasp less than normal in the case where guaranteeing not harmful drafting, and twist factor grasp bigger than normal；The relative humidity control in workshop exists
65%；
Main technologic parameters: spun yarn Dry Weight per Unit 18.6g/100m, nip gauge 2.2mm, roller gauge 18mm × 30mm, the twist
75.3 twirls/10cm, rings is serial using PG, and 26.5 times of total draft multiple, 1.25 times of back area draft；
(8), the process uses Germany's Schlafhorst AC338 type automatic winder, due to polyester fiber, bamboo pulp fiber, Chinese fiber crops
Cohesive force between fiber is poor, but fiber crops, bamboo, the wettability power of terylene are stronger, to select the technique of small tension receiving coil, low velocity former
Then, the air pressure of automatic joint, air splicer wants sufficient, and for the control of workshop relative humidity 65%, winder speed is 750m/min,
Cotton knot 6.0.
