Comparative example 1 and embodiment 1 are contrasted and understands, the difference is that only of the two: embodiment 1 is multiple after using first first twist
The plying mode twisted with the fingers prepares base line, and comparative example 1 only carries out the most twisted and plied, and is provided without the plying side of retwist after first first twist
Formula prepares base line.The technical specification of carbon fiber stitching thread prepared by method described in employing comparative example 1 is: diameter 0.5mm, and stretching is strong
Degree 677MPa, breaking strain 0.7%.Compared with Example 1, carbon fiber stitching thread is pliable and tough for comparative example 1 made carbon fiber stitching thread
Property poor, line in use easily clot, easily fluff after abrasion, online in form carbon hair ball and gather, automatically pool capital during the straight tiling of support
Becoming 4 strands, after trimming, automatic untwisting, affects sewing process and is carried out continuously.It follows that the present invention is by retwist after the first first twist of employing
Plying mode, make sth. made by twisting to contrary two strands of first twist carbon fiber lines plying, it is possible to the carbon fiber unwinding after effectively reducing twisting is beaten
Volume, the problem efficiently solving carbon fiber sewability.
Comparative example 2
This comparative example uses polyacrylonitrile-based carbon fibre to be that raw material is prepared the concrete preparation method of carbon fiber stitching thread and included
Following steps:
Step one, (technical specification of selected silvalin is: fineness 1K, line density to choose 4 strands of polyacrylonitrile-based carbon fibre yarns
66g/1000m, density 1.76g/cm3, tensile strength 3.53GPa), then according to the twisting mode that S twists with the fingers is to wherein 2 strands of polypropylene
Itrile group carbon fiber yarn carries out first twist plying, obtains S single, according to Z twist with the fingers twisting mode to other 2 strands of polyacrylonitrile-based carbon fibres
Dimension yarn carries out first twist plying, obtains Z single；The twist of described first twist plying is 200 twists/m；
Step 2, twisting mode retwist plying S single described in step one and Z single twisted with the fingers according to S, obtain base
Line；The twist of described retwist plying is 300 twists/m；
