Embodiment 1
[0031] Such as figure 1 Shown, a kind of stretch-cut strip making method of cotton-type fiber is characterized in that, comprises the steps:
[0032] (1), prepare the tow to be drawn and cut:
[0033] (1), lead the tow to be stretched and cut into strips from the tow box;
[0034] (two), tension balance
[0035] The tow to be drawn from the tow box is fed to a tension equalization device composed of several pairs of tension rollers arranged up and down to balance the tension of each filament bundle and each filament in the filament bundle.
[0036] (3) Spreading treatment
[0037] In the above-mentioned stretch-cut sliver-making method for cotton-type fibers, the tow to be stretch-cut slivered drawn out from the tow box is fed by a spreader with spiral convex strips extending from the middle to both sides on one or more surfaces. Spreading rollers composed of rollers can gradually spread each filament in the filament bundle within a certain width under the action of the sp...
Embodiment 2
[0047] Such as figure 1 Shown, a kind of stretch-cut strip making method of cotton-type fiber is characterized in that, comprises the steps:
[0048] (1), prepare the tow to be drawn and cut:
[0049] (1), lead the tow to be stretched and cut into strips from the tow box;
[0050] (two), tension balance
[0051] The tow to be drawn from the tow box is fed to a tension equalization device composed of several pairs of tension rollers arranged up and down to balance the tension of each filament bundle and each filament in the filament bundle.
[0052] (3) Spreading treatment
[0053] In the above-mentioned stretch-cut sliver-making method for cotton-type fibers, the tow to be stretch-cut slivered drawn out from the tow box is fed by a spreader with spiral convex strips extending from the middle to both sides on one or more surfaces. Spreading rollers composed of rollers can gradually spread each filament in the filament bundle within a certain width under the action of the sp...
