The invention discloses a kind of length complex yarn and its production method.The complex yarn is combined by long filament and spun yarn, and long filament is heart yarn, spun yarn is sheath yarn, and heart yarn and sheath yarn are eccentric structure, and wherein long filament is polypropylene filament yarn, accounts for the 10~50% of the complex yarn gross weight.Compared with the conventional spinning frame cored processing method of length composite yarn, cored effect is more superior, and uses polypropylene filament yarn to be incubated, the effect of water-absorbing fast-drying as heart yarn.
Description
Technical field
The present invention relates to a kind of new cotton yarn and its production method, and in particular to a kind of long and short fiber containing polypropylene fibre is answered
Yarns and its production method.
Background technology
As the improvement of people's living standards, everybody is for textile material, particularly functional material, from past
That body is covered in requirement, be slowly evolved into it is present to water-absorbing fast-drying, heating, insulation etc. functional demand, material more become
In diversification.
Wherein, people can prefer for cotton/Modal/viscose glue for the cellulose fibre class functional material of representative,
Because the sense of touch of this kind of material is more comfortable, and gentle non-stimulated, but all using the textile of this fibrid raw material, nothing
Method obtains water-absorbing fast-drying, insulation etc. feature；And strength is not too high, even by above-mentioned fiber and staple fibre
Blending, dimensional stability is simply also improved to a certain extent and controls the occurrence probability of broken hole, but anti-fluffing and anti-pilling
Problem still fails to solve.So it is highly desirable can develop one kind can be used for produce feel be enough and cellulose fibre face
Material matches in excellence or beauty, but also with water-absorbing fast-drying, the yarn of the fabric of heat insulation function.
Also occur the such yarn in part on the market at present, for example one kind is disclosed in patent document CN200310103660
Really twisted with the fingers by the chopped fiber beam being drafted and by the synthetic fibers multifilament of fibrillation on spinning frame by adding while the side wound
The length complex yarn that formula obtains, long filament after electric shredding at the front roller with the chopped fiber Shu Chonghe after drawing-off, twisting,
By the yarn that above-mentioned processing obtains due to being that chopped fiber beam looping lives synthetic fibers multifilament, or synthetic fibers multifilament and short fibre
Dimension mixing, although the strength of yarn is improved, the stability of production and processing needs further to be improved, particularly short fibre
Dimension is in covered filament, if the looping that can stablize lives to have a huge impact production below and dyeing, if bag
Cover and be not sufficiently stable, be then very easy to phenomena such as band occur.In addition, fibre-opening unit is installed at long filament end so that long filament script
Interlacing is opened, and so can more increase the difficulty of cladding.
The content of the invention
It is an object of the invention to provide one kind cladding stabilization, and with water-absorbing fast-drying, the length composite yarn of heat insulation function
Line and its production method.
The technical solution of the present invention：
In the length complex yarn of the present invention, long filament is heart yarn, spun yarn is sheath yarn, and heart yarn and sheath yarn are eccentric structure, its
Middle long filament is polypropylene filament yarn, accounts for the 10~50% of the complex yarn gross weight.
Compared with the conventional spinning frame cored processing method of length composite yarn, cored is carried out using two rove, and pass through
Self-criticism to reducing rove spacing, reaches the effect being evenly coated.In addition, using polypropylene filament yarn as heart yarn, using its light weight,
The characteristics of water guide, it is incubated, the effect of water-absorbing fast-drying.
Brief description of the drawings
（1）Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the covering yarn structural representation of the present invention, and Fig. 5, Fig. 6, Fig. 7 are the bag of comparative example
Core yarn structure schematic diagram, whereinFor heart yarn,For sheath yarn.
Embodiment
In the length complex yarn of the present invention, long filament is heart yarn, spun yarn is sheath yarn, and from the point of view of fiber cross-sectional, heart yarn
It is eccentric structure with sheath yarn, i.e., heart yarn is not among sheath yarn, but the part beyond the centre of sheath yarn, wherein long filament are
Polypropylene filament yarn, account for the 10~50% of the complex yarn gross weight.Polypropylene fiber has lot of advantages, such as in general chemical fiber
Midst density is most light；With core sucting action, vapor can be transmitted by the capillary in fabric, water guide rapid-drying properties are better than other fibers
Deng.
In view of using polypropylene fibre full-drawn yarn（Abbreviation FDY）, filament is relatively sliding, it is possible to which core can not be completely covered by sheath yarn occur
The phenomenon of yarn；And FDY shrinkage factor is not as good as false twist processing yarn（Abbreviation DTY）, it is difficult to shrink into again after heart yarn exposes.Cause
This, polypropylene filament yarn used in the present invention is preferably polypropylene fibre DTY.
The fiber number of polypropylene filament yarn used in the present invention is preferably 30~75 Denier（Abbreviation D）.Within this range, it is easy to add
Work, and covered effect is good.
The fibrous raw material of spun yarn used in the present invention is preferably the one or more in viscose glue, polyester, acrylic fibers and cotton.
The length complex yarn of the present invention is twist yarn, and twist direction is Z twist directions or S twist directions.According to the sth. made by twisting of yarn
To, when for Z twist directions when, long filament is and to the right no more than right side rove diameter positioned at the center-right position of two rove beams
1/2 position.When for S twist directions when, long filament is positioned at the center-left position of two rove beams, and same to the left to be no more than left side rove straight
1/2 position in footpath., so can be advantageously in carrying when long filament particularly being inserted into the center-right position of rove it is preferred that Z twist directions
The stability of high clad structure.
We are by substantial amounts of experiment discovery repeatedly, the length complex yarn obtained using the cored processing method of routine, outside
The chopped fiber of side is difficult to encase the long filament of inner side completely.The production method of the length composite yarn of the present invention is as follows：Using spun yarn
Machine, first chopped fiber is formed after 2 rove beams successively by single hole horn mouth, buncher, ensure 2 rove interfasciculars every 0~
Long filament is fed among front roller and apron on the basis of 1mm, after then being twisted with rove beam in front roller exit
Compound, 1.5~2.0 times of spinning frame back zone drafting multiple, if back zone drafting multiple is less than 1.5, back zone tension in the roving is big, it is difficult to
Form cored structure.The bell-mouthed width of single hole is preferably 2~3mm；The width of buncher is preferably 2~4mm.
In the present invention, the tension force of long filament is preferably 20~60g.Here tension force locates as long filament creel to guide
Take turns the tension force of section.The tension force of long filament can effectively control the generation of the problems such as final products foaming, looping etc. within this range.
Embodiment
With reference to embodiment and comparative example, the invention will be further described.
The method of testing of each performance and parameter involved in the present invention is as follows.
（1）Clad ratio
30 root long degree 5cm complex yarn is taken, after being wrapped up with viscose staple fibre bar, fills in the copper coin with diameter 1.5mm holes
It is interior, observed after cutting off both ends with blade in microscope.When heart yarn exposes outside in sheath yarn, then it is judged as not coating；When not there is core
Yarn exposes outside in sheath yarn, then is judged as coating.Counted according to the result of 30, calculate cladding radical and account for the hundred of total radical
Ratio is divided to obtain clad ratio.
