Description
Technical field
The present invention relates to a kind of online preparation method of moisture absorption yarn of Seluofle compound spinning method, belong to textile process
Technical field.
Technical background
Seluofle spinning method is a kind of spinning method developed on the basis of SEILE textile.Go out as China is open
Version thing《Xi'an University of Engineering Science ＆ Technology journal》Time of disclosure is in April, 2007, and article name is " cotton/terylene polyester filament
Sirofil composite yarn yarn-forming mechanisms performance study ", the principle of the technology is for polyester filament directly by guide wire apparatus from front roller
Feeding, and keep certain spacing to export with the staple fiber yarn Jing Guo drawing-off at jaw before front roller, through twist triangle zone
Converge respectively after slight first twisting at convergent point, then strengthen twisting with the fingers and closing again, be then winding on spool and form match
Network Fei Er yarns.Seluofle compound spinning method has the characteristics that the long filament looping good to staple fiber, which can be significantly
Degree improves yarn strength and yarn quality.Want to assign yarn special performance if being disadvantageous in that, must be in yarn final finishing
Modified process is added in process.
The method that document report cotton is modified at present is very much, such as Chinese public publication《Printing and dyeing》Time of disclosure is 2012
In April in year, article name is " adaptability of cotton cation modifier modified technique ", and the document discloses infusion process, pads-cold dome
Method, pad-bake method and pad-four kinds of the steam method method cation-modified to cotton.Cotton four kinds of methods more than
Modified, coloring uniformly and greatly improves the utilization rate of dyestuff very much, and modification liquid is impregnated with completely in provable above method
Onto cotton.It is disadvantageous in that conventional method is yarn to be modified after resultant yarn so that production link complicates, increase
Production cost, extends the production cycle.
The content of the invention
For above-mentioned problem, it is an object of the invention to provide a kind of moisture absorption of Seluofle compound spinning method
The online preparation method of yarn, to achieve these goals, its technical solution is：
A kind of online preparation method of moisture absorption yarn of Seluofle compound spinning method, the preparation method are directed to Seluofle
Composite spinning, dress is modified using being set on the polyester filament of ring throstle to the polyester filament running way between front roller
Put, reforming apparatus is made of volume control device and damping device, in front roller to setting drying unit, terylene between ring bobbin
The modified device of long filament is run to front roller after applying modification liquid, with being run after rear roller, middle roller drawing-off to front roller
The cotton rove at place converges, and is applied with the polyester filament of modification liquid and twists at the preceding jaw of front roller that to form moisture absorption thin with cotton rove
Yarn, spun yarn drying device drying are wound up on ring bobbin.Wherein, modification liquid is by absolute ethyl alcohol and fatty alcohol polyoxyethylene ether
Mix, absolute ethyl alcohol and fatty alcohol polyoxyethylene ether mass ratio are 97:3-91:9.
Due to good to staple fiber with long filament using Seluofle compound spinning method using above technical scheme, the present invention
Good looping feature, applies modification liquid by reforming apparatus during Seluofle composite spinning to polyester filament, modified
The polyester filament of liquid effect twists to obtain the yarn with moisture absorbing with cotton rove.The modified device of polyester filament, which applies, to be modified
Liquid rear surface is covered with modification liquid, when polyester filament and cotton rove are mutually wound, polyester filament at preceding jaw because twisting acts on
It is wrapped over spatially spiral shape on the outside of cotton rove, the modification liquid on polyester filament surface can partly be transferred to the cotton fiber being in contact with it
On.Since modification liquid is made of ethanol and fatty alcohol polyoxyethylene ether, wherein the content of ethanol is more than 90%, and ethanol has
Good wetting property, when the modification liquid on polyester filament is contacted with cotton fiber ethanol can drive fatty alcohol polyoxyethylene ether to
Shift in cotton fiber direction；Meanwhile fatty alcohol polyoxyethylene ether itself is a kind of bleeding agent again, possess good permeance property, with
Under ethanol collective effect, modification liquid is easier to be transferred to from polyester filament on the cotton rove being in contact with it.Cotton fiber absorbing fats
After alcohol polyoxyethylene ether, the increase of fiber moisture pick-up properties.In summary 2 points, the spun yarn length direction side formed from twist triangle zone
The state of one section of polyester filament, one section of cotton fiber is presented, the modification liquid on polyester filament is shifted to the cotton fiber being in contact with it.This
The hydrophily for inventing cotton fiber in the yarn prepared effectively improves in original basis, and polyester filament surface hydrophilicity itself
It is poor, certain hydrophily is endowed through the modified polyester filament surface of hydrophilic finishing agent, then washing after hydrophilic finishing agent acts on
Compared with the polyester cotton blended yarn of the Seluofle composite spinning without hydrophilic modifying, its hydrophily can be carried accordingly silk/cotton blended yarn
Height, that is, the hygroscopicity of yarn prepared will can effectively improve.
The aqueous solvent selected in conventional modification liquid is changed into organic solvent ethanol by the present invention, utilizes the volatile spy of ethanol
Property, as the solvent of modification liquid；The drying unit that the present invention is set has further speeded up the evaporation rate of ethanol, realizes
The purpose of yarn flash baking, this is irrealizable as solvent using water in common process.Therefore, selection is easy to volatilize
Solvent of the ethanol as modification liquid, after the drying of the 3rd spun yarn drying device, ethanol volatilization leaves behind modified material, then the 3rd
Spun yarn be with dry state on ring bobbin.The present invention changes yarn during Seluofle composite spinning
Property, compared with the technique that routine is modified yarn after spinning, without increasing modified device, realizing reduces production cost and subtracts
The purpose of few production cycle, and the polyester cotton blended yarn phase of the yarn and not modified Seluofle composite spinning of the invention prepared
Than the hydrophilicity and hygroscopicity of yarn effectively improve.
