In spinning and spinning last handling process, the selection of spinning machine has semicontinuous weaving loom and continuous weaving loom, and from technology and equipment two aspects, these two kinds of spinning machines exist following difference:
1, from the angle of production technology, semi-continuous spinning machine is that spinning is separated with post processing (post processing comprises washing, oven dry, becomes the steps such as cylinder), completes separately, and semi-continuous spinning machine is mainly responsible for spinning part; And continuous spinning machine is that spinning is concentrated in together and completed continuously with post processing (post processing comprises washing, oven dry, becomes the steps such as cylinder) operation, the responsible institute from spinning to post processing of continuous spinning in steps.
2, from the angle of device structure, semi-continuous spinning machine comprises glue feed mechanism, thread spraying structure, strand shaping mechanism, spinning roller mechanism, wiper mechanism and winding mechanism, and the product obtaining is the spinning cake that falls into centrifugal cylinder; And continuous spinning machine has glue feed mechanism, thread spraying structure, strand shaping mechanism, spinning roller mechanism, wiper mechanism, there is no winding mechanism, strand directly enters the mechanisms such as drip washing, oven dry, finally obtains the silk cylinder of coiling and molding.
Difference based on above two kinds of spinning machines, its pluses and minuses are separately as follows:
1, semi-continuous spinning machine (as shown in Figure 1-Figure 3):
Advantage: owing to there being the post-processing step carrying out separately, and also have the process of low-temp desulfurization, low temperature long time drying, product to have that intensity is high, whiteness is high in post-processing step, the feature that strand is soft beautiful;
Shortcoming: spin speed low, post processing expense is high, increases production cost.
2, continuous spinning machine:
