Performance and spinnability depend primarily on the person's character and spinning melt temperature of various components.Effectively increase after with the addition of the first compound
Entanglement point and the steric hindrance between melt macromolecular are added, the activity of macromolecular chain and segment is deteriorated, so that modified poly-
The rheological property of ester spinning melt is poor compared to the rheological property of single polyester fondant.Therefore present invention employs gradual change type heating
It (is specially to be melted in spinning screw, temperature setting is warming up to 15 DEG C/min that speed and gradual heating and heat preservation, which are melted,
27,8 DEG C of holding 20-60min, are warming up to 290 DEG C of holding 30-60min with 5 DEG C/min, 310 DEG C of holdings are warming up to 3 DEG C/min
5-30min) so that the rheological characteristic of melt drops to minimum, it is to avoid larger fluctuation occurs for spinning melt viscosity, and reduces lousiness
And broken end, effectively improve the spinnability of spinning melt.
5th, side-blown wind velocity and temperature:Applicant has found by numerous studies, due to there are two kinds of component melts compared with list
One compound is different, to obtain normal stretching thread, should select the rational technique bar such as side-blown wind velocity and temperature
Part, shows cross air blasting speed control in 0.21-0.25m/s, preferably 0.23m/s, side-blown air temperature control by many experimental results
System is at 25-27 DEG C, preferably 26 DEG C, can be effectively improved the defect of spinning melt rheological property and spinnability difference, improve spinning coil
Fill forming quality and after-drawing performance;
6th, on drawing process:Applicant has found by numerous studies, due to there are two kinds of component melts, causes the later stage to be drawn
It is different to stretch compared to single compound, therefore, and rate of deformation during stretching can not be too big, otherwise easily causes the heated work of strand
Reduced with the time and produce very big stretching tensile stress, fiber is produced lousiness broken end and uniformity variation.Found by research
Draw ratio selection is advisable between 3.3-3.8, and preferably 3.45, tensile stress and rate of extension can be effectively reduced, reduces and opens
The fluctuation of power, improves the degree of orientation and crystallinity of fiber.
7th, creative first compound that adds carries out melt spinning, is found by test:Preparation-obtained fiber
Long filament damping 24h in normal conditions, using YG061 type electronics single fiber strength testers, test speed is 20mm/min, and gauge is
20mm, is tested 50 times, pre-tension is 0.1cN.Length 40mm, line density/dtex=1.38.Add the modification of the first compound
Polyester filaments fracture strength can reach 6.7
(cN·dtcx-1), elongation at break (%) is 23.8, and ratio resistance is 6.7*105(Ω·cm);Unmodified polyester
Resin fracture intensity can reach 4.9 (cNdtcx-1), elongation at break (%) is 20.8, and ratio resistance is 1.8*106(Ω·
cm);It can be seen that polyester fiber Jing Guo Gai Xing and adding the first compound and melt and obtain fiber filament fracture strength and obtain
To effective lifting, fiber flexibility is also improved, and ratio resistance is reduced, and can effectively reduce electrostatic generation.
8th, as the method for covering on the two sides of base fabric fabric with gluing liquid, the coating that gluing liquid can be coated with liquid
Mode.According to bed scraper for coating mode, tree is promoted by carrying on the back the pressure of two sides application appropriateness from the table of synthetic fabrics
Fat is impregnated with to intertexture portion, it is easy to improve the area ratio of the resin in intertexture portion interface.It is preferred that by scraper and bottom to base
Cloth contact is set to 0.5~4.0N/cm.Contact mentioned here is the width with the scraper contacted with synthetic fabrics
Degree is except the value for the power for pushing scraper to synthetic fabrics.In the case where contact is less than 0.5N/cm, the coating of resin
Amount is possible to become excessive, storage, flexibility is suffered damage, weight increase.If contact is more than 4.0N/cm,
It is possible to that on the surface of synthetic fabrics uniform resin covering film can not be formed.It is preferred that contact be 1.0~3.0N/
Cm, most preferred contact is 2.5N/cm.
The first and second components are employed in gluing liquid:
