Description
Technical field
The present invention relates to a kind of covering yarn, in particular to a kind of preparation method with environmentally friendly elastic core-spun yarn.
Background technique
Covering yarn: covering yarn generally using strength and all preferable filament of synthetic fibre of elastic force as core filaments, hair, glue by outsourcing cotton
The staple fibers such as glue fiber are twisted together and the yarn that is spun into.Covering yarn has the excellent performance of long filament heart yarn and outsourcing staple fiber concurrently.
It can use the performance and surface characteristics of the excellent physical property of heart yarn chemical-fibres filaments and outsourcing staple fiber, give full play to two kinds
The speciality of fiber and the deficiency for making up them.At present using RING SPINNING covering yarn as mainstream in industrial production, it is vortexed spun core-spun yarn, gas
Stream spun core-spun yarn also has certain scale.
Be vortexed spinning technique: air injection air vortex spinning machine is grown up on the basis of Air-Jet Spinning, and air vortex spinning is freely
End spinning belongs to true twirl structure.Air-jet eddy-current spinning principle: the air-flow that spray orifice sprays forms negative pressuren zone at nozzle entrance, negative
Under pressure effect, the parallel fibers beam of premenstrual roller draft is inhaled into nozzle.The front end of fibre bundle around guid needle by
It is forming the pull of the tail end of yarn and is importing in doffing tube, effect of its rear end by high-speed eddy axial thrust load, part
Fiber lodges in doffing tube inlet in umbrella, and the fiber of lodging is exposed in the gyration airflow of spray orifice ejection, with returning for air-flow
In turning to yarn tail, the real staple yarn output for twisting shape is formed.Vortex spinning Yarn filoplume is few, any surface finish, and anti-pilling property is remote
Better than the product of other spinning forms；Good hygroscopicity.Fabric sheen is good, and soft to have bony again, good stability of the dimension is wear-resisting.
Sorona:Sorona polymer is the advanced polymer platform of the newest release of E.I.Du Pont Company.It can not only assign fibre
The unique performance of peacekeeping fabric, and biotechnology is utilized revolutionaryly in chemical fibre raw material, in the hope of functions of textile fabrics and ring
The perfect combination of guarantor.
Bicomponent fibers containing sorona have outstanding elastic recovery, and spandex, which is not added, can be realized comfortable stretching
Property；With cotton feel, comfortable feel.Sorona polymer chlorine-resistant is alkaline-resisting, and easy dyeing is beautiful in colour after dyeing.
SORONA polymer using biochemical method production has following triple values of environmental protection
1 has 37% raw material from natural reproducible resource, rather than petrochemical material, to reduce the dependence to petroleum resources；
The Sorona polymer of 2 identical yield, compared with the nylon polymer based on petrochemical material, Sorona compares in being made
The latter consumes 30% energy less；
The Sorona polymer of 3 identical yield, compared with the nylon polymer based on petrochemical material, Sorona compares in being made
The latter discharges 63% carbon dioxide (i.e. greenhouse gases) less.
Summary of the invention
The present invention mainly solves the deficiencies in the prior art, mainly solves present in existing idea yarn product
Some shortcomings.Use bi-component sorona polymer for the vortex spun core-spun yarn of core filaments, the woven fabric of resultant yarn institute has
Outstanding elastic recovery, comfortable feel, easy dyeing, and it is beautiful in colour after dyeing, have simultaneously as core filaments SORONA polymer
