In actual production, it is considered that length can just occur mutually entanglement more than the filoplume of 2mm, endanger knitting for yarn
Property, therefore it is considered that the filoplume of 3mm and the above is harmful filoplume.The hairiness index of harmful filoplume of sizing is shown in Table 7.10cm length
Yarn in the radical of the unilateral filoplume up to 3mm be referred to as hairiness index.
Table 7 is harmful to the hairiness index of filoplume
2. the overall balance analysis of orthogonal test
Test result is analyzed with synthesis necessary technology：By test result ranking, most preferably tested number 1, most
Poor is tested number 9.Then three performance indications to testing are analyzed respectively and are shown in Table 8, during the K of first three rows is same row,
The result of the test sum of same level, pin number are numbered for level, such as K3It is the result of the test sum of 3 levels in same row；Below
Three rows areIt is the mean value of K, i.e. K/n, n is the test number (TN) of same level in same row；Last column is extreme difference R, is same
The difference of the maxima and minima of K in one row.
8 Three factors-levels test result analysis of table
As can be seen from Table 8, for different performance indications, different factor influence degrees be it is different,
So it is irrational that the primary and secondary order of the importance of three performance Index Influences is united.Different performance indications institutes is right
The optimal case answered is different, can obtain comprehensive optimal case hence with synthesis necessary technology：Each index is distinguished
It is analyzed, table 9 is the analysis to fracture strength, and table 10 is the analysis to elongation at break, and table 11 is the analysis to wearability,
Table 12 is the analysis to filoplume.
9 fracture strength of table is analyzed
10 elongation at break of table is analyzed
11 Analysis on Wear of table
12 filoplume of table is analyzed
Understand A factors to fracture strength, elongation at break, wearability, hair according to the analysis of table 9, table 10, table 11, table 12
The influence of plumage is maximum, and effect of the B factors to wearability is poor, and C factors are secondary cause.For elongation at break, A factors
Impact effect with B factors is identical.
The tendency chart that three factors are acted on to slashing performance：The effect tendency chart of A factors is shown in Fig. 1, the effect trend of B factors
Figure is shown in Fig. 2, and the effect tendency chart of C factors is shown in Fig. 3.
Factor A：To fracture strength, elongation at break, wearability and filoplume, it is that A factors are best, and it is strong for rupturing
Degree, elongation at break, wearability and filoplume, A are principal element again, answer emphasis to consider.A as can be seen from Figure 13When sizing it is disconnected
Resistance to spalling, wearability and filoplume, are best, A1When elongation at break it is best.
Factor B：To fracture strength, wearability and filoplume, slightly worse than A factor, elongation at break is identical with A factors, from
Fig. 2 can be seen that B1When the fracture strength of sizing, wearability and filoplume, be best, choose B1。
Factor C：For four performance indications, C factors are all secondary causes, according to majority rule.Choose
C1。
The above analysis, optimal case is：A3B1C1.That is PVA205 is 6.5% for 2.0%, CD-99, solid propenoic acid
Salt is 2.0%.
Recognized by above-mentioned data analysis, using slurry sizing of the present invention after, for improving, yarn weaving effect is non-
Chang Xianzhu, wherein PVA205 and CD-99 effect is obvious, is the principal element for affecting starch finishing effect；Acrylates is secondary cause,
The wearability of yarn is played the role of relatively strong.By contrasting to the yarn property before and after starching, it is found that starch finishing effect is very bright
Aobvious, enhancing rate reaches 29%, and it is 16% to subtract the rate of stretching, and wear-resisting increase rate is even more and reaches 147%, and filoplume reduced rate also reaches
99.4%.
In formula of size without PVA (embodiment 1) sizing performance：Enhancing rate is lower than the enhancing rate for having PVA formula of size
5%, subtract the rate of stretching low by 2%；But wearability difference is larger, lower by 63% than there is PVA formula of size；Filoplume reduced rate ratio has PVA to starch
Material formula is low by 4.4%.It can be seen that the formula of size without PVA stretching property and filoplume are functional by force, but wearability is not enough, if
PVA is not adopted, the rate of sizing can be increased, increase and decrease is coating, increases sizing wear resistant, so as to meet weaving needs.
The present invention is described in detail above in conjunction with embodiment, but, person of ordinary skill in the field can
Understand, on the premise of without departing from present inventive concept, the design parameter of each in above-described embodiment can also be changed, shape
Into multiple specific embodiments, the common excursion of the present invention is, here is no longer described in detail one by one.
