Index such as the table 1 of each embodiment:
| The measurement index experiment numbers | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| Whiteness | 63.9 | 70.7 | 72.8 | 78.6 | 79.2 |
| Capillary effect (cm) | 8.9 | 11 | 11.1 | 9.8 | 10 |
| Intensity (cN) | 351.2 | 350.18 | 351.04 | 326.68 | 310.5 |
Should reach the requirement of semi-products, i.e. 75-79 left and right in factory during to the pre-treatment standard of pineapple fibre yarn.As can be known, boiled and boil in technique by data in table, the sample whiteness being along with the concentration of Tea Saponin solution increases and increases, until change littlely from 20 g/l-24 g/l whiteness, and boiling of 20 g/l Tea Saponin solution boiled processing and also can be reached factory to the requirement of semi-products.If improve again solution concentration, increase to some extent in disposal cost, and brute force meeting decline to some extent along with the increase of concentration, think that therefore the boiling of Tea Saponin solution of 20 g/l boiled the best when processing.
From the capillary effect data, the capillary effect of untreated pineapple fibre yarn is 7.5cm, and the capillary effect of the pineapple fibre yarn after processing all more untreated pineapple fibre yarn is good, and mean value is about 10.2cm, requiring capillary effect to reach 8-9cm in factory gets final product, and minimum in 5 embodiment 8.9cm being arranged also, the capillary effect of the pineapple fibre yarn after therefore processing all meets the requirements.
From powerful data, according to pure dimity technical indicator (FZ/T32002-1992) as can be known, the single thread fracture strength of the yarn that untreated pineapple fibre thread density is 34-38tex is not less than 20.5(cN/tex), the single thread fracture strength of pineapple fibre raw yarn should be not less than 20.5*40.5=830.25cN.But the single thread fracture strength of the actual pineapple fibre raw yarn of surveying only is 419cN, is about 50% of single thread fracture strength in pure dimity technical indicator.And through statistics, the pineapple fibre fineness of yarn after processing approximately reduces by 18%, and the pineapple fibre fineness of yarn after processing is about 40.5*(1-18%)=33.21tex.According to pure dimity technical indicator (TZ/T32002-1992) as can be known, ramie yarn density is that the single thread fracture strength of 25-33tex is not less than 19, therefore the single thread fracture strength of the pineapple fibre yarn after processing should be not less than 19*33.21=630.99cN.Because the single thread fracture strength of pineapple fibre raw yarn accounts for 50% of single thread fracture strength in pure dimity technical indicator, if the pineapple fibre yarn strength after processing reaches 630.99*50%=315.5cN and gets final product, except embodiment 5, other embodiment can satisfy processing requirements as can be known from the table data.
From hairiness number, boil boil process after the hairiness number of yarn as shown in table 2:
| The measurement index experiment numbers | 1mm | 2mm | 3mm | 4mm | 5mm | 6mm | 7mm | 8mm |
| Embodiment 1 | 22.1 | 29.2 | 39.7 | 56.6 | 73.3 | 101 | 132.1 | 98.9 |
| Embodiment 2 | 20.4 | 29 | 40.5 | 59.8 | 84.3 | 123.3 | 162.9 | 106.5 |
| Embodiment 3 | 24.6 | 30.9 | 40.6 | 57 | 78.9 | 118.2 | 153.6 | 102.9 |
| Embodiment 4 | 19.67 | 24.44 | 35.44 | 54.11 | 74.44 | 101.89 | 133.52 | 95.89 |
| Embodiment 5 | 18.22 | 24.99 | 34 | 52 | 72.35 | 100 | 130.52 | 95.89 |
As shown in Table 2 the pineapple fibre yarn after treatment hairiness number significantly reduce, wherein the hairiness number with 1-6mm is the most remarkable, and 7, the hairiness number of 8mm slightly increases.After its reason may be Tea Saponin pre-treatment processing, the filoplume that great majority are more tiny was dissolved, so hairiness number significantly reduces.Therefore 7, the long hairiness number of 8mm slightly increases and the tiny filoplume of small part processes and also can slough a part of colloid due to money, makes that between them, sticking effect weakens, and becomes long filoplume; On the other hand, after the pineapple fibre yarn was processed through Tea Saponin, the dietary fibres on pina fibre surface were dissolved, become comparatively smooth, and therefore short and small filoplume easily by stretching out, makes 7, the 8mm hairiness number has certain increase.
In sum, from whiteness, capillary effect, brute force and filoplume indices, embodiment 4 is best processing methods.
