Analysis embodiment 1, as shown in Table 1, refine Desizing Step rolled using merceration → and cold dome puts → open width washing process, place
Obtain tearing resistance on warp-wise and broadwise for the modified poly ester yarn/PFY intertexture after reason and seam slippage is all significantly larger than
The requirement of concerned countries standard, and property in terms of diffusion time of dripping, dry and wet colorfastness to rubbing and anti-hair balling-up for the intertexture
Can evaluate and also be above national standard, it can thus be appreciated that the refine desizing that the present invention provides can be in the premise not affecting performance
The lower pre-treatment meeting modified poly ester yarn/PFY intertexture.
Analyze embodiment 2～6 further, from table 2～6, refine Desizing Step is changed under weak base normal temperature condition
Material processing, the tearing resistance on warp-wise and broadwise of gained modified poly ester yarn/PFY intertexture and seam slippage are all high
In the requirement of concerned countries standard, wherein, the polyester that the weft yarn tearing resistance containing modified poly ester yarn is below as warp thread is long
The tearing resistance of silk, and both seam slippage difference on warp-wise and broadwise are little；Additionally, above-mentioned intertexture is in diffusion of dripping
The performance evaluation of time, dry and wet colorfastness to rubbing and anti-hair balling-up aspect is also above national standard it can be seen that the present invention
Using weak base room temperature pre-treating technology can meet the processing requirement of modified poly ester yarn/PFY intertexture well.
