Problems solved by technology

[0006] If the warp stop device is not used, the warp breakage cannot be found in time, and the warp breakage of more than 6m in weaving will cause the problem of cloth surface cutting. The cloth bundle joint after cutting also has considerable impact on product quality and downstream customers. influences

Abstract

The invention discloses size for electronic grade glass fiber fine yarn weaving and a blending method of the size and belongs to the technical field of size weaving. The size is characterized by containing the following components in percentage by mass: 1.48-1.52% of polyvinyl alcohol PVA-205, 4.45-4.55% of polyvinyl alcohol P-401 and the balance of water. The blending method comprises the following steps: raising the temperature of water having the ratio of 45-55% to 75-85 DEG C and stirring, wherein the stirring rate is 46-56 r / min; adding PVA-205 according to a ratio; stirring for 280-330 seconds, and adding P-401 according to a ratio; maintaining the temperature and stirring for 30-50 minutes, and cooling to 57-66 DEG C, wherein the stirring rate is 18-22 r / min, and the temperature ismaintained constant for 18-22 minutes; and stopping stirring, and adding the residual water, thereby obtaining the product. After being improved by using the size, warp yarns can also maintain clear and smooth yarn mouths due to long-term operation, and before the yarns enter a warp yarn stop piece, the yarn mouths are clear and distinct in hierarchy.

Description

technical field [0001] A slurry for weaving electronic-grade glass fiber spun yarn and a blending method thereof, belonging to the technical field of weaving slurry. Background technique [0002] Due to the previous process of "parallel axis" during winding, in order to reduce the friction of the warp at the same point and the winding and filling of the weaving shaft, a left and right swinging device will be added to the reed at the take-up part to ensure the axial surface winding of the weaving shaft The smoothness of the winding avoids the unevenness of the axial surface of the weaving shaft caused by the warp yarn winding at the same point. It is for this reason that all the weaving beams also oscillate with the warp threads as the loom unwinds. [0003] Electronic grade glass fiber spun yarn D450 (specification) is weaving and weaving. The warp yarn swings left and right during the unwinding process of the weaving shaft. Due to static electricity caused by friction and ...
