Application in alkali containing glass fibre varicosity yarn.
(2) background technology
Bulked glass yarn be using glass fiber bulk strand yarn through being passed through pressure-air special device it is puffing and
Into although process and uncomplicated, imparting the effect of glass fibre is special, it has the high intensity of continuous fiber and short concurrently
The bulkiness of fiber, be a kind of high temperature resistant, low thermal conductivity, it is corrosion-resistant, high hold empty amount, filtration efficiency it is harmless
New material.
Because of peculiar advantage of the bulked glass yarn in performance, it is widely used in automobile, building, heat preservation, sound insulation etc.
Application field.Such as clutch disc, muffler, thermostable heat insulation material, the wall wall cloth of building field.Wide in range application neck
Domain imparts the huge market prospects of bulked glass yarn product.It is continuous with global economy and composite industry
Development, under the stimulation of the macro policies such as country's " adjusting structure ", the development of the high-end fields such as automobile, architectural shape, high temperature resistant
It is placed on the position more protruded.With the continuous development of composite material application technology, buiky yarn application field has new again
It expands, for example in drawing and extruding section bar, the particularly position of structure and surface complexity, the introducing of buiky yarn can increase the suction of fiber
Glue amount ensures to obtain good filling at some labyrinths of product, so as to promote the quality of product surface and mechanics
Intensity.
Meet the performance requirement of more than buiky yarn, it is generally following (using not with yarn performance requirement to glass fiber bulk strand
Saturated polyester resin, content of glass fiber is 75%, by taking 600tex as an example)：
● performance indicator：
| Test event | Shear strength | Expansion rate |
| ≥40MPa | 3%-5% |
The test of woven glass roving fabric impregnation sample shear strength：Method is shown in that instrument is set described in ASTM D2344
It is standby to include gumming device, drawing force machine, fixture etc., reference standard ASTM D2344.
Bulked glass yarn expansion rate is tested：Test puffing preceding line density T1, the line density T2 after test is puffing, meter
Calculate (T2-T1)/T1*100%, as expansion rate.
It, need to be by developing a kind of novel size thus under the premise of constant using E glass ingredients：Reach good
Expansion effect, i.e., it is puffing after fiber can fully and uniformly scatter, expansion rate is high.The compatibility requirements of product and resin simultaneously
It is good, to meet the requirement of end article mechanical property.
(3) invention content
The technical problems to be solved by the invention are to provide a kind of size and its application, the nothing produced using the size
