Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] The glass fiber yarn penetration speed detection method of the present embodiment comprises:
[0024] Step S1, use the skein length measuring instrument to wind the glass fiber yarn bundle to be measured, stick double-sided adhesive tape on the yarn bundle at a predetermined distance, and divide the yarn bundle into several sections. The skein length measuring instrument can make the yarn bundle evenly wound, and the double-sided adhesive sticks and fix...

The invention relates to the technical field of glass fiber yarn manufacturing, and discloses a glass fiber yarn soaking speed detecting method. The method comprises the steps of winding a glass fiberyarn bundle to be tested by using a crepe length measuring instrument, pasting a double-sided tape on the yarn bundle at a predetermined distance, and diving the yarn bundle into several segments; S2, cutting the yarn bundle into segments to form a uniform yarn bundle segment, and pasting both ends of the cut yarn bundle segments with the double-sided tape; S3, firstly transversely pasting the cut yarn bundle segment on a first prepreg, and longitudinally pasting the cut yarn bundle segment on the first prepreg; S4, placing the first prepreg over a detection panel to uniformly pour the resinonto a yarn bundle layer, covering a second prepreg, scraping the second prepreg with a squeegee, impregnating the yarn bundle with a resin, and detecting the soaking speed of the yarn bundle by a detecting plate. The method avoids the situation that the difference in local light transmittance after resin impregnation caused by the unevenness after the yarn bundle is large, so that a soaking speedtest is more accurate.
Description
technical field [0001] The invention relates to the technical field of glass fiber yarn manufacturing, in particular to a method for detecting the penetration speed of glass fiber yarn. Background technique [0002] The current method for detecting the resin penetration rate of glass fiber yarn is to place the target ring on a flat detection workbench; then cover the target ring with a square polyester film of about 40 cm; cut the glass fiber yarn bundle into 8 centimeter length, and then artificially sprinkle the glass fiber yarn on the polyester film; pour the prepared resin evenly on the yarn, cover another piece of polyester film, and clearly observe the time when the target ring is seen. It is the time for the glass fiber yarn to be soaked by the resin. The shorter the time, the faster the soaking speed, indicating that the sizing agent on the glass fiber yarn has a better match with the resin. [0003] In this test method, due to the large randomness of manual yarn sp...
