[0013] However, in the method described in Patent Document 1, although the twisting process is omitted to obtain a glass strand with a small number of twists, since the glass strand is wound around a coreless cylindrical shape with a large inner diameter and thereby taken inward and relaxed, It is not easy to use and is the most widely used today, the known manufacturing weaving equipment that will be wound into a single cone-shaped glass yarn package and inserted into the rod to fix it
[0014] Furthermore, in the method disclosed in Patent Document 2, when the glass cloth used is a thin strand like glass yarn, since the thickness of the strand wound around the coreless cylinder becomes thin, defects such as dents are likely to occur during transportation.
Moreover, in order to offset the twisting caused by high-speed relaxation, the pedestal must also rotate at high speed. When glass yarn is used for warp yarns, it needs to correspond to the number of warp yarns (usually about 500). problem on

Abstract

The present invention provided a glass yarn which has <=0.3 twist count (real twist count) after being unwound from the glass yarn package. The real twist count is the comparative twist count of the one inch glass yarn after being unwound from the glass yarn package.

Description

technical field [0001] The present invention relates to a glass yarn (glassyam), glass yarn package (glassyam package) and glass yarn loosen (loosen) method, which is used in the preparation of glass cloth suitable for weaving substrates for printed circuit boards (printed circuit board). Background technique [0002] In general, glass cloth is manufactured as follows. First, the molten glass is pulled out from a plurality of nozzles installed at the bottom of a platinum bushing and spun, and the surface of the glass filaments is coated with a sizing agent, and tens to thousands of glass filaments are bundled into glass ropes ( glassstrand) is wound into a block, and secondly, the outer layer of the block loosens the glass rope, and is wound on the reel while twisting to make glass yarn packaging for glass cloth. Furthermore, the loose glass yarn wrapped by glass yarn is used for warp and weft, and an air jet chamber is used to manufacture woven glass cloth. [0003] There...
