Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings.
By polymerizable mesogenic composite fibre silk for manufacturing high-precision printing silk screen, the silk screen is used to produce PDP, partly lead
Body, TP, solar cell, printed wiring etc..
As shown in figure 1, polymerizable mesogenic composite fibre silk be core-skin type composite construction, including periphery clad 1 and inside
Sandwich layer 2.Sandwich layer 2 is thermotropic liquid crystalline polymer material, and its proportion is 80%-90%, and clad 1 is poly- ethylene
The mixed materials of diol ester and thermotropic liquid crystalline polymer, its proportion is 10%-20%.Clad 1 is island type structure, bag
Inner core 11 and outer layer 12 are included, inner core 11 is thermotropic liquid crystalline polymer material, and outer layer 12 is polyethylene terephthalate material.Bag
Coating 1 is islands-in-sea bicomponent fibre：Dispersed phase polymer is set uniformly to be embedded in the composite fibre formed in continuous phase polymer.Dispersion
Gathering compound is longitudinally discontinuously arranged along fiber, in fento shape, claims matrix-fento type；Claim decentralized, lotus root in rod is scattered
Core pattern.Two-phase is by the double composition sea-island fibres of title that similar heterogeneity polymer is constituted.Fiber has many characteristic properties, such as moisture absorption
Property, antistatic behaviour, warming and photosensitive color-changing, dyeability, flame retardancy etc..By two kinds of polymer difference or mixed melting, spinning
Through super drawing and shearing deformation during silk, island mutually turns into filamentary form, and gained composite fibre is by rational stretching and warm
Treatment can also turn into the good high-shrinkage fibre of physical property.The marine facies of sea-island fibre are dissolved, be left fiber number be 0.01~
A branch of superfine fibre of 0.2 denier.If island is mutually taken out, hollow fibre is can be made into.Sea-island fibre can be used to do filtering material, nonwoven
Weave cotton cloth and various knitwear and woven product.
It is core-sheath compound fibre between clad and sandwich layer：Two kinds of polymer is longitudinally continuous to form cortex along fiber respectively
With the fiber of sandwich layer, there are the concentric and micro- odd-shaped cross section of eccentric circular, core and core-skin to be the core-sheath compound fibre of abnormity, with spy
Different material is the fiber of core, and with property, such as X-ray absorbs fiber, infrared ray absorbing fiber, conductive fiber, optical fiber
Deng.Fiber with special material as skin, such as caking property fiber, hydrophilic and oleophylic fiber, special gloss fiber.Such as it is with polyamide fibre
Skin, terylene are the composite fibre of core, just have the advantage that nylon dyeing is good, wearability is strong and terylene modulus is high, elasticity is good concurrently.Profit
With skin-core structure, the fiber of specific use can also be manufactured.Fire-retardant polymer is such as made into core, conventional polyester for leather makes fire-retardant
Fiber.
As shown in table 1, the mesh number scope of silk screen is 20- to the parameter of the silk screen being made up of above-mentioned polymerizable mesogenic composite fibre silk
