Description
Technical field
The invention belongs to production of chemical fibre fields, are related to the melt and dissolved method of chemical fibre, and in particular to composite fibre
Screw extruding method.
Background technique
It is raw material that chemical fibre, which is with natural polymer or artificial synthesized high-molecular compound, is spun by preparation
The processes such as silk stock solution, the spinning and post-processing fiber obtained with textile performance.Chemical fibre is divided into staple fibre and conjunction again
At fiber two major classes: 1. staple fibre is chemical fibre made of raw material with natural polymer (such as cellulose), such as viscous
Glue fiber, acetate fiber.2. synthetic fibers, such as poly- using artificial synthesized high-molecular compound as chemical fibre made of raw material
Ester fiber, poly- phthalein amine fiber, poly internal olefins nitrile fiber.Chemical fibre have intensity is high, wear-resisting, density is small, elasticity is good, it is not mouldy,
It is not afraid of the advantages that damaging by worms, is quick-drying washable, but the disadvantage is that dyeability is poor, electrostatic is big, fast light and weatherability is poor, water imbibition is poor.
Staple fibre mainly has viscose rayon, nitric acid ester fiber, acetate fiber, cuprammonium rayon and Azlon etc.,
Its towel viscose rayon point common viscose fiber and has New Viscose Fibre (such as high-wet-modulus fibres, superpower viscous of outstanding properties again
Glue fiber and permanent curl viscose rayon etc.).
Synthetic fibers mainly have daiamid-6 fiber, and poly internal olefins nitrile fiber gathers and matches fiber, poly internal olefins fiber, polyvinyl alcohol contracting
Formaldehyde fibers and special fibre.The 1950s carries out the study on the modification of synthetic fibers, mainly with physically or chemically side
Method improves the properties such as moisture absorption, dyeing, antistatic, fire-resistant, anti-pollution, the anti pilling of synthetic fibers, while also adding chemical fibre
Kind.
Usually first spinning melt is made in natural or synthesis polymer substance or inorganic matter by the preparation of chemical fibre
Or solution, liquid thread is then extruded as by spinning head (plate) by filtering, metering, then solidification forms fiber.At this time
Fiber is known as as-spun fibre, its mechanical property is very poor, it is necessary to by a series of post-processing procedures could accord with textile process and
Requirement.Post-processing carries out stretching and heat setting mainly for fiber, to improve the mechanical property and dimensional stability of fiber:
Stretching is to be orientated macromolecular or structural unit in as-spun fibre along fiber axis, and heat setting mainly makes internal stress pine in fiber
It relaxes.When spinning filament yarn, cylinder can be wound into through above-mentioned operation；The processes such as curling, cutting and packing must also be increased when staple fiber processed.
Polyamide fibre, that is, Fypro, wearability is better than cotton fiber, there is 4-6g/D under strength dry state, and strong has 7-
9.5g/D, sunlight resistance can protrude, and fiber is made at 255-260 DEG C or so, with melt spinning in fusing point.Terylene is a kind of common fibre
Dimension, wrinkle resistance is good, but terylene regain is low, there was only 0.4% when under standard state, when use phenomenon easy to produce static electricity.Hair
Bright people has found in the implementation of the present invention, and polyamide fibre and terylene are combined with each other and can make full use of respective advantage, and
Respective disadvantage is made up.But because of the difference of recipe ingredient and dosage, in the technical process of extrusion forming, different is squeezed
It presses temperature to influence the quality of composite fibre very big, in the case where no experiment condition or knowhow, has much not
Predictable factor.
