Description
Technical field
The present invention relates to a kind of method that yarn of Seluofle composite spinning dyes online, belongs to textile process technology neck
Domain.
Background technology
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 viscose glue polyester filament
Sirofil composite yarn yarn-forming mechanisms performance study ", the principle of the technology directly pass through guide wire apparatus the past for viscose glue polyester filament
Roller is fed, and keeps certain spacing to export with the cotton cotton rove yarn Jing Guo drawing-off at jaw before front roller, through twisting
Trigonum is converged after slightly twisting for the first time respectively at convergent point, then strengthens twisting with the fingers and closing again, is then winding on spool
Form seluofle yarn.Therefore, Seluofle compound spinning method has the characteristics that the long filament looping good to staple fiber, the spinning
Method can increase substantially yarn strength and yarn quality.Want to assign yarn special performance if being disadvantageous in that, must be
Modified process is added in yarn finishing process.
It presently, there are and improve the research of fiber or yarn dyeing performance by adding extra-fine wool powders, such as China is open
Publication《Xi'an Polytechnic University's journal》Time of disclosure is 14 months 2009, and article name is " polyvinyl alcohol/extra-fine wool powders
The preparation of blend film and its dyeability ", the document, which describes, to be mixed together to extra-fine wool powders and PVA to prepare PVA/
The method of extra-fine wool powders blend film, and the more former PVA of dye-uptake for testing the blend film is significantly lifted.Its shortcoming exists
Extra-fine wool powders are added to yarn before this method is resultant yarn so that production link complicates, and adds production cost, extends
Production cycle.
The content of the invention
For above-mentioned problem, it is an object of the invention to provide a kind of yarn of Seluofle composite spinning is online
The method of dyeing, to achieve these goals, its technical solution is：
A kind of method that yarn of Seluofle composite spinning dyes online, the preparation method are directed to Seluofle Compound spinning
Yarn, using dyeing apparatus is set in the approach that polyester filament is run on ring throstle, dyeing apparatus is by volume control device
Formed with damping device, front roller is to setting drying unit, the dyed dress of polyester filament on ring throstle between ring bobbin
Put and run after applying mill base to front roller, converged with being run after rear roller, middle roller drawing-off to the cotton rove at front roller,
The polyester filament and cotton rove for being applied with mill base twist to form coloured spun yarn at the preceding jaw of front roller, coloured spun yarn drying
Device drying is wound up on ring bobbin.Wherein, the mill base by dyeing wool powder, UDT, ethanol and distilled water allocate and
Into, it is respectively by mass percentage,
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 mill base to polyester filament by dyeing apparatus during Seluofle composite spinning, applies mill base
Polyester filament and cotton rove afterwards twists to obtain coloured spun yarn.The dyed device of polyester filament applies mill base rear surface and is covered with color
Slurry, when polyester filament and cotton rove are mutually wound at preceding jaw because of twisting effect, polyester filament is with spatially spiral shape looping
On the outside of cotton fiber, the mill base on polyester filament surface can be partly transferred on the cotton fiber being in contact with it.Due to ethanol in mill base
Content more than 10%, and ethanol has good wetting property, the ethanol when the mill base on polyester filament is contacted with cotton fiber
Mill base can be driven to be shifted to cotton fiber direction.One section of polyester filament one is presented in the spun yarn length direction side formed from twist triangle zone
The state of section cotton fiber, the mill base on polyester filament is shifted to the cotton fiber being in contact with it, by the mill base of polyester filament institute band
The cotton fiber covering limited, mill base completely cannot be presented the spun yarn length direction side formed from twist triangle zone is measured, so carefully
One section of dyeing, one section of achromophil state is presented in yarn length direction, therefore can prepare coloured spun yarn.
The drying unit that the present invention is set has further speeded up the evaporation rate of ethanol and distilled water, and it is quick to realize spun yarn
The purpose of drying.After coloured spun yarn drying device drying, ethanol and distilled water volatilization leave behind dyeing fibroin and UDT, then have
Color spun yarn be with dry state in spinning cylinder.The present invention contaminates spun yarn during Seluofle composite spinning online
Color, compared with routine is after spun yarn sizing to the technique of spun yarn dyeing, without increasing dyeing installation, realizes reduction production cost
With the purpose for reducing the production cycle, and the polyester cotton blending of the spun yarn for preparing of the present invention and not dyed Seluofle composite spinning
Yarn is compared, and spun yarn surface has obvious coloring effect.
