Abstract
The invention discloses a U-shaped hollow Dacron draw-textured yarn and a preparation method thereof. The technical process includes the steps of: adding polyester melt; sequentially passing through a booster pump, a melt transport pipe, a spinning box, a metering pump and a spinning assembly including a spinneret plate; cooling, oiling and winding; further sequentially passing through a pre-netting device, a yarn cutter, a first roller, a first heat box, a cooling plate, a false twister, a tension meter, a second roller, a network nozzle, a second heat box, a third roller and an oil wheel; winding for shaping, namely obtaining the required product. According to the preparation method, two kinds of jet micropores are designed on the same spinneret plate, namely U-shaped holes and hollow holes, so that the a bunch of yarns include U-shaped yarns as well as hollow yarns; meanwhile, through the arrangement design of the two kinds of jet micropores, the hollow yarns are wrapped in the U-shaped yarns, so that the damage to the sections of the hollow yarns in a sequential false twisting process is greatly reduced, and the functionality of the product is significantly promoted. The fabric prepared according to the invention has very wide application prospect in the field of garment materials and fabrics.
Description
Technical field
The present invention relates to a kind of hollow adds " u "-shaped terylene draw textured yarn and preparation method thereof, particularly provide a kind of using
Both contain " u "-shaped, and have the POY precursor of hollow to add the preparation method of " u "-shaped terylene draw textured yarn to process hollow again.
Background technology
With the raising of Levels of Social Economic Development and living standards of the people, people are to the fabric of dress ornament, style and style
To the comfortableness of dress, there is higher requirement.Traditional fibre section is circular, and fabric breathability, hygroscopicity are poor, and fabric is close
Degree is big, and profiled filament is because the change of its section morphology is so as to have the property of uniqueness compared with general chemical fibre, main body
It is now the following aspects：The different geometric cross sections of fiber can make light produce refraction and light splitting as prism, and then reflects
Colorful light, and make fiber produce a kind of gloss of superbright；Gap between fiber and yarn is many, than the common textile of same specification
Product have good gas permeability；Fiber surface area is big, and absorption property is good, can be used as material for air purification；The cohesive force of fiber is strong,
Fluffing and pilling effect can greatly reduce, and also can improve drapability and wrinkle resistance etc., profiled filament has above-mentioned many excellent
Performance, is increasingly favored by market.
Hollow adds " u "-shaped terylene draw textured yarn, and, as a kind of Profiled fibre, section is more special for it, has multiple
The characteristic that profiled filament has, in terms of hollow plus " u "-shaped section：The groove having, have moisture absorption sweat discharging functions, good permeability,
Elasticity is good, anti-pilling property is good, has deeper indent groove, hollow round hole, woven into fabric feel is softly warming.Enjoy consumer
Favor.
The mode of production that domestic at present existing hollow adds " u "-shaped terylene draw textured yarn be respectively produced " u "-shaped POY and
Hollow POY, reuses elasticizer false twisting screening network and is composited.POY production efficiency is made to reduce by one under this mode of production
Times, production cost improves；In false-twisted process, hollow POY is easy to be damaged by friction plate, and fiber feature declines；Just also have
It is that the difference of two kinds of POY interior qualities brings difficulty to the quality stable homogeneous of DTY.
Content of the invention
The technical problem to be solved in the invention is that and overcomes existing hollow to add " u "-shaped terylene draw textured yarn producer
The limitation of formula, provides a kind of hollow to add " u "-shaped terylene draw textured yarn and preparation method thereof, and this preparation method is in same spray
Filament plate is designed with two kinds of spinneret orifices, a kind of " u "-shaped hole, a kind of hollow hole so that existing " u "-shaped silk in a synnema, in having again
Empty silk is so that POY precursor quality discrepancy diminishes, production efficiency greatly improves；Pass through to two kinds of spinneret orifice arrangement designs simultaneously,
So that macaroni yarn is wrapped in inside " u "-shaped silk, in Zai Hou road false-twisted process, the section of macaroni yarn is damaged and substantially reduce, product
Feature is obviously improved.
For solving the above problems, the present invention can be achieved through the following technical solutions：
A kind of hollow adds " u "-shaped terylene draw textured yarn preparation method, its technological process be polyester fondant → booster pump →
The filament spinning component → cool down → oil of melt conveying pipeline → spinning manifold → measuring pump → containing spinneret → wind → pre- net dress
Put → yarn cutter → first roller → the first hot tank → coldplate → scroll tube → tensiometer → the second roller → network nozzle →
Second hot tank → three rollers → finish oil disc → coiling and molding, obtains hollow and adds " U " shape terylene draw textured yarn, described spinneret
On be provided with " u "-shaped hole and two kinds of spinneret orifices of hollow hole, described " u "-shaped hole is both sides 2 slot lower end and middle 1
Slot two ends connect, and the two slot long axis angles interconnecting are in that 90 ° of angles form " u "-shaped geometric form
Shape；Described hollow hole forms a circular geometry by three sections of scallop holes.
As the preferred technical solution of the present invention：
Hollow of the present invention adds " u "-shaped terylene draw textured yarn preparation method, described " u "-shaped hole and hollow hole section
Amass and compare 1:1, it is 0.03mm2—0.05mm2；Described " u "-shaped hole is identical with the hole depth of hollow hole, and draw ratio 2:1～3:1.
Hollow of the present invention adds " u "-shaped terylene draw textured yarn preparation method, and described spinneret orifice is evenly distributed on
With spinneret center as the center of circle, on equidistant five concentric circles, " u "-shaped hole is arranged on two concentric circles of outermost, hollow
Hole is arranged on three concentric circles in inner side.
Hollow of the present invention adds " u "-shaped terylene draw textured yarn preparation method, and " u "-shaped hole opening direction points to spinneret
Plate center, and into θ angle with the connecting line at spinneret center with " u "-shaped hole center, and angle is 5 ° -10 °.
Hollow of the present invention adds " u "-shaped terylene draw textured yarn preparation method, and the described type of cooling blows cooling for ring.
Hollow of the present invention adds " u "-shaped terylene draw textured yarn preparation method, and described oiling method is oiled using double
Mode, will a synnema priority through two identical oil nozzles, strand is carried out before and after oil.
The present invention also proposes a kind of hollow prepared by method made above and adds " u "-shaped terylene draw textured yarn.
Because using above technical scheme, a kind of hollow of the present invention adds the preparation method of " u "-shaped terylene draw textured yarn,
Its advantage shows：On the basis of existing production equipment, by changing the technological parameter such as spinneret and oiling method it is
Can produce；The fabric that the hollow that the method is obtained adds prepared by " u "-shaped terylene draw textured yarn has moisture absorption sweat discharging functions, breathes freely
Property good, anti-pilling and elasticity good, woven into fabric feel is softly warming, gloss is soft, and fiber surface area is big, and absorption property is good,
Have very wide in the application prospect of garment material and fabric arts.
