Description
Technical field
The present invention is relevant for lax (loosen) method of a kind of glass thread (glassyam), organdy package (glassyam package) and glass thread, and use is weaved in preparation and is applicable to the glass woven fabric of printed circuit board (PCB) (printed circuit board) with base material.
Background technology
Generally speaking, glass woven fabric is made in following mode.At first, melten glass is pulled out and spinning by most nozzles of the platinum system of being arranged at sleeve (bushing) bottom, behind the surface coating collecting agent with fibrous glass, the glass rope bundle (glassstrand) of tens of～fibrous glass institute boundling of thousands of is wound in block, secondly, the lax glass rope bundle of skin by block is wound in afterturn on the spool to make the organdy package that glass woven fabric is used.Moreover the glass thread lax by organdy package is used in organizine and tram, and uses the blast injection chamber to make the braiding glass woven fabric.
, the organic component that is attached to glass woven fabric is burnt to remove (heating de-oiling) by heating thereafter, this glass woven fabric is dipped in thermosetting resin after, storehouse also makes hardening of resin, to make the laminate plate of use in printed circuit board.
The glass woven fabric of use in printed circuit board reduces in order not make its quality, and require its fluffing less, the heating de-oiling is good etc.
And, because the densification of the distribution on printed circuit board (PCB) in recent years, for the uniformization of the specific inductance capacity that reaches printed circuit board (PCB) and promote processability, widen glass thread, the narrow and small glass woven fabric in slit and pursue.Because the little words of slubbing number of glass thread are then widened easily, then need the little glass thread of slubbing number in order to obtain the narrow and small glass woven fabric in slit.
The afterturn of saying glass thread is exactly in the purpose of giving the fluffing generation that prevents glass thread.Therefore, in order to make the narrow and small glass woven fabric in slit, by the fibrous glass delivery volume of adjustment twisted filament manufacture craft and the revolution of spool (bobbin), making the little fibrous glass of more known slubbing number (0.3～2.0 S afterturn or Z afterturn), however the fluffing of twisted filament technology easily generations so be difficult for manufacturing good glass thread.
For this point, consider to omit twisted filament technology and make the method (for example being to please refer to patent documentation 1) of the glass rope bundle that the little glass woven fabric of slubbing number uses.That is be, behind the glass rope wrapping coiled block of the method with fine-count yarn (yarn numbercount), lax directly to be used in the manufacturing braiding of glass woven fabric by block.
And, also consider by the rove of the cylindric winding of centreless packing by interior get make it lax when, the pedestal of revolution rove packing is with the payment afterturn, with the method (for example being to please refer to patent documentation 2) that obtains the little glass rope bundle of slubbing number.That is be, by getting in the rove packing rope bundle make it lax when, the pedestal of revolution rove packing is with the payment afterturn, the slubbing number of the rope bundle that is relaxed is kept the no afterturn that is wound in the rove packed state.
[patent documentation 1]
Japan discloses flat 9-268034 communique in early days
[patent documentation 2]
Japan discloses flat 5-84838 communique in early days
But, the method that patent documentation 1 is put down in writing, obtain the little glass rope bundle of slubbing number though omit twisted filament technology, owing to the wrapping of glass rope be around in the coreless roll with large diameter cylindric and thus in get and relax, the most widely be used now and be difficult for using, the spool that is wound in the organdy package of single taper is inserted known manufacturing braiding apparatus fixing in the rod.
And, patent documentation 2 disclosed methods, in the glass woven fabric use as the thin occasion of the rope bundle of glass thread since be wrapped in centreless thickness attenuation cylindraceous so the bad of recessed grade taken place easily when transporting.And in order to offset by the afterturn due at a high speed lax, pedestal also must high-revolving revolution, when glass thread is used in organizine, needs the bar number (about about 500 usually) of corresponding organizine, and has problems economically with on the equipment.
Summary of the invention
Purpose of the present invention, the relaxation method of a kind of glass thread, organdy package and glass thread is provided, can use known manufacturing braiding apparatus and can make and widen the narrow and small glass woven fabric in easy slit, and then can promote the uniformization and the processability of the specific inductance capacity of printed circuit board (PCB).
Glass thread of the present invention is relaxed slubbing number (actual slubbing number) afterwards below 0.3 by organdy package.It " actual slubbing number " herein refers to by organdy package the pairing slubbing time of glass thread 1 inch after lax.
The slubbing number that is wound in the glass thread of organdy package state is preferably more than 0.01.This slubbing number is based on JIS R 3420 and determined.
And organdy package of the present invention can be discerned the lax direction in order to the lax glass thread of untiing afterturn.
And, the relaxation method of glass thread of the present invention, the limit is given the afterturn limit and is supplied with glass rope bundle by the direction of principal axis of spool in twisted filament technology, form organdy package on the spool to be wound in, and by with the supplying party of glass rope bundle in the opposite direction, by aforementioned organdy package glass thread is got outward with lax, so that the afterturn of glass thread is untied." getting outward " herein refers to the method by the lax glass thread of outer circumferential side of glass thread.
The slubbing number of glass thread, usually, in JIS R 3420 with the cooresponding stranding number of twists of glass thread 1 inch that is wound in the spool state as regulation, be that center steering spool and lax glass thread are with determined by axle with spool.But, the actual glass thread that uses, in order to relax keeping under the fixing state of spool, glass thread is an afterturn around one week of spool whenever, the slubbing number of the actual glass thread that uses is different with the slubbing number that is wound in spool.Compare to the slubbing number of the glass thread of JIS R 3420 defineds,, therefore examine with actual slubbing number because the slubbing number (actual slubbing number) of the glass thread behind actual use lax and the characteristic of glass woven fabric have darker relation.
Glass thread of the present invention, owing to the slubbing number (actual slubbing number) after lax from organdy package is below 0.3, be preferably below 0.2, therefore can use known manufacturing braiding apparatus to make the glass woven fabric that braiding is widened easily, the gap is narrow and small, promote the uniformization and the processability of the specific inductance capacity of printed circuit board (PCB).That is be, to be fixed in known manufacturing braiding apparatus and the spool of glass thread dress can be inserted in the rod because glass thread of the present invention once had been wound in organdy package.And because actual slubbing number is below 0.3, glass thread is widened easily when the braiding glass woven fabric, the easy stenosis in slit of glass woven fabric is little.And the afterturn direction of lax glass thread can be S afterturn (afterturn of left-hand screw direction), can also be Z afterturn (afterturn of right-hand screw direction).
And glass thread of the present invention, at the slubbing number that is wound in the organdy package state is more than 0.01, be preferably the words more than 0.1, owing to when twisted filament, give afterturn, thereby be difficult for fluffing, and when lax, so that the afterturn of being given when the twisted filament is untied, and can make that actual slubbing number is 0 with the afterturn when lax.
Glass thread of the present invention, to untie the lax of afterturn, preferable because actual slubbing number diminishes easily with the direction of the supply opposite sense of glass rope bundle.But the slubbing number that is wrapped in the organdy package state is greater than 0.6, even untie the lax of afterturn, actual slubbing number is also easily greater than 0.3.
Organdy package of the present invention owing to the lax direction that can discern in order to the lax glass thread of untiing afterturn, and can be untied the lax of afterturn with correct lax direction, can access the little glass thread of actual slubbing number.Can discern the organdy package of the lax direction of glass thread, it for example is the different organdy package of both ends length that does not twine the spool of glass thread, the organdy package of the bipyramid shape that coning angle is different, the spool that the shape of end or apparent condition are different, and, also can use the organdy package of marks such as the point that is applied with the lax direction of expression, line, arrow, particularly be applied with the organdy package of lax direction mark, because the lax direction of identification glass thread is preferable easily.
The diameter of spool is preferably 10～150mm, is more preferred from 20～100mm.Words less than 10mm, the occasion that twining amount is many is twined thickness and is become big, and the initial and last actual slubbing number that is wrapped in the glass thread of organdy package differs and becomes big, and, be not easy to be difficult for keeping high efficiency by the speed of high speed rotary spool with the lifting spool.On the other hand, greater than 150mm,, the effect of untiing afterturn when relaxing is difficult for making actual slubbing number to diminish owing to diminishing.
The shape of organdy package, be preferably to be wound in and be difficult for avalanche, can twine or relax, can be the arbitrary shape of spindle, single taper, both sides' shape (double square), biconial (double taper) etc., particularly diconical words are because glass thread winding that can be smooth or lax and preferable.
No matter it is that paper, ABS resin, acrylic resin, metal etc. all can for the material of spool.And, being shaped as barrel-contoured words and when making braiding or gaiting, can inserting in the rod and pack of spool with the fixing glass yarn.As winding that can be smooth for the words of cylinder or laxly be difficult for fluffing.And, be middle thin cylinder as spool, then glass thread is difficult for producing avalanche and preferable.
And, relaxation method according to glass thread of the present invention, in twisted filament technology, the limit is given the afterturn limit and is supplied with glass rope bundle by the direction of principal axis of spool, being wound in spool is difficult for taking place to form the fluffing that organdy package was produced, and, because the spool that can be used in organdy package inserts known manufacturing braiding apparatus fixing in the rod, therefore can use known manufacturing braiding apparatus.Moreover, by from the opposite sense of the direction of the supply of glass rope bundle, get glass thread outward to relax by organdy package obtain the glass thread that slubbing number diminishes easily owing to untie the afterturn of glass thread easily.
The direction of the supply of glass rope bundle, for the wrapping of glass rope around when, supply with the direction of glass rope bundle towards spool.
Even, glass rope Shu Tongchang uses in drying regime, glass rope bundle is being wound in the state of block, the state of the glass rope bundle before being wound in organdy package, or can make it dry in the state of organdy package system, particularly the state of the glass rope bundle before being wound in organdy package makes it air-dry, glass rope bundle by the collecting agent adjacency each other or glass thread can not stick together mutually each other, when lax, be difficult for lifting or broken filaments, be difficult for reducing the manufacturing braid efficiency and preferable.
