(3) by the end of the computational analysis front spinning silver mixing operation
The first: is from tensile elongation.The length that A in raw material is stretched is 19.525584133.45M, and the 218.36M strip be not evenly distributed viewed from length aspect is be uniformly distributed strip 3.9/100000, can ignore.Spin this A of silver mixing before thinking fully to be mixed in 50KG raw material.
The second: also close number of times from self.From above 2.2 calculating, only consider the strip of bucketful distribution, A in raw material self also closes number of times: comb silver mixing again, comb a pin again, combing two pins due to feeding strip length does not limit self not and close again, combing is also combined into 3 times, comb three pins again and be combined into 3+6=30 time, comb four pins again and be combined into 30+5=245 time, frontly spin silver mixing and be combined into 24510+1=2451 time.Before spin in 8 barrels of wool tops of machine under silver mixing and have the strip in four barrels fewer than other four barrels and close 1 time, compare can ignore with 2451 times for this 1 time, because for color, the error human eye of 1/2451 is difficult to distinguish, for composition, the error of 1/2451=0.04% is well below industry standard.From then on alternatively this A bright has fully been mixed in 50KG raw material.
The third: is from being stretched bar heavily.Be that 20G/M calculates by the sliver weight of multiple comb silver mixing feeding, to front spinning machine under silver mixing, initial A is heavily 20/9.52=3.5810 by the bar after the drawing-off of each road -6g/M.Raw materials used by spinning is ramuscule hair, and fineness average out to 0.6tex, length average out to 70mm, the weight of a wool is 4.210 -6g, the weight of a wool is greater than A and is front spun the weight of 1M wool top after silver mixing drawing-off as can be seen here, illustrate A drafted become filamentary spot distribution, also the random distribution of fiber in wool top is demonstrated, whether a wool fibre just decides A and is evenly distributed, and also illustrates that A is evenly distributed from this aspect.
Reach a conclusion from above analysis: 50KG wool top, certain 1M strip is from multiple comb silver mixing operation, can fully be mixed in process in this 50KG raw material, and just can be evenly to front spinning silver mixing operation, along with front spinning a pin---the further drawing-off in Qian Fang tetra-road and immixture, A strip can mix more even, thorough with 50KG strip.
The 1M strip that length only accounts for 50KG wool top 0.004% fully can be mixed in overall raw material in process, illustrates that also conjunction and the drawing-off in process is huge silver mixing resource, should be used well.Can think that silver mixing is exactly that a kind of wool top is mixed in overall raw material, in actual production, require the wool top of the different form and aspect heterogeneities mixed, often kind of wool top length is all much larger than 1M, and being bound to each other, it is even to be mixed.Based on this, small lot is mixed new bar technique and is exactly: the wool top of different form and aspect heterogeneity according to the feeding of certain radical, according to shaping weight, production with fixed lengths, and when criticizing, each raw material also can replace mutually.
Contrast test
Experimental design
Choose spending of a collection of 120kg in production brown, spin 2 × 16.67tex yarn, wherein there are 8 form and aspect, each form and aspect weight is divided equally open, form two batches of X and Y respectively, by traditional silver mixing explained hereafter, produce by small lot silver mixing new technology for Y batch, the contrast complexity of silver mixing and the mixing uniformity of process for X batch.
That chooses divides equally for 60kg raw material form and aspect are as follows, and the wool top bar of often kind of form and aspect is heavy is all 20g/m.

Y criticizes small quantities of silver mixing new technology: each 1 of A, B, C, D, E, F, G, H every form and aspect strip, amounts to and close 8, drawing-off 7.6 times, shaping 21g/m, fixed length 357m.The form and aspect strip lacked substitutes with many.
All produce according to following table technique for two batches of contrast test
Test is followed the tracks of
Silver mixing efficiency comparison
From silver mixing technological design, by above 4.3 and 4.4 known traditional silver mixing complex process, be difficult to hold, calculate with the time long, and small quantities of silver mixing new technology is simple, easily grasp, the used time is short.From the execution technique used time, comb on gilling machine again at same, the 60kg raw material of X batch completes silver mixing task used time 255min, and this time comprises the raw material time that takes performed in technical process, gone up batch time, driving time for four times, the clear car time; The 60kg raw material of Y batch completes silver mixing task used time 66min.The tradition silver mixing time is 3.86 times of new small quantities of silver mixing time, under traditional silver mixing process concept, when performing silver mixing, always there is incomplete mixing phenomenon, especially more outstanding in batch stage, incomplete mixing phenomenon need not be considered when small quantities of silver mixing new technology performs, simply be easy to operation.
Mixed effect in production process under each operation after machine compares
To comb under silver mixing after machine again, each form and aspect of X batch and Y batch all do not mix, X batch of lower machine the first seven barrel of color does not have difference, last barrel of surface portion strip due to batch reason and other seven barrels of colors have any different, and Y batch of lower machine strip first three barrel of indifference, other five barrels of strips are different because the form and aspect strip lacked is substituted overall color by other form and aspect strips.
Comb under a pin after machine again, each form and aspect of X batch and Y batch still do not mix.10 barrels of strip colors of X batch of lower machine are identical, and 10 barrels, the strip color of Y batch of lower machine is different.
Comb again under two pins after machine, X batch every barrel strip color is tending towards even, identical, and Y batch of every barrel of color is different but be tending towards close.
Under combing after machine, X batch every barrel strip color uniformity, reaches colour mixture requirement.Y batch of every barrel of color is slightly different very close.Only observe the mixing situation of Y batch below.
Comb again under three pins after machine, every barrel of strip color of Y batch is identical.The strip of aberration is had always in surface and the bottom of the barrel of bar bucket to this operation, comparison surface strip color according to the computational processes of 2 are known.
Comb again under four pins after machine, Y batch mixes, and X, Y two batches of colors are identical.The difference in X, Y two batches of colors is not found in ensuing operation.
Y batch of finished product yarn is randomly drawed 10,16# knitting machine connects and knits, no color differnece.X, Y two batches of yarns are connected on 16# knitting machine and knits, solid colour.
Visible, Y batch adopting small lot silver mixing new technology, mixing to combing four pins again.
The shakedown of small lot silver mixing have selected 3 different colours spinning 2 × 16.67tex yarn, Different Weight batch.
3 small quantities of silver mixing new technologies are as follows:
The coffee-like silver mixing technique of 22kg pure wool:
Amount to and close 9, drawing-off 8.57 times, shaping 21g/m, fixed length 131m, batch time assorted strip mutual generation.
