Abstract
The invention provides a spinning method for high-count high-quality embedded compact spun yarn. Filament yarn and short fiber rough yarn can be spun, the quantity of harmful hairiness can be effectively reduced, and the resultant yarn quality can be improved. The spinning method includes the following steps that two pieces of short fiber rough yarn are placed in the middle, two pieces of filament yarn are distributed at the two sides of the short fiber rough yarn respectively, the four pieces of yarn are divided into two groups, and each group comprises one piece of short fiber rough yarn and one piece of filament yarn; when the four pieces of yarn pass through a horizontal line of a front jaw of a drawing roller, downward air negative pressure is added below a twisting trigonum plane in the opposite direction; one pair of filament yarn and short fiber rough yarn are twisted in a first twisting trigonum, and the other pair of short fiber rough yarn and filament yarn are twisted in a second twisting trigonum; the semi-finished product yarn after being twisted in the first twisting trigonum and the second twisting trigonum enters a third twisting trigonum and is twisted through a steel collar bead ring. The air negative pressure ranges from 0.15 Mpa to 0.3 Mpa.
Description
Technical field
The present invention relates to the spinning method of the embedded Compact-spun Yarn: of a kind of high count high-quality, belong to textile processing field.
Background technology
Embedded spinning method is the innovation based on a kind of technology in traditional ring spinning yarn method, and this innovation makes staple fibre constraint by long filament in spinning process, and the free fiber that swims is less, thus decreases the formation of Yarn filoplume from source.But still can there is a part because do not receive the fibroplastic harmful filoplume being greater than 3mm of constraint very well, especially when the length initial modulus that is longer or fiber of fiber is higher time, free fiber will increase, harmful hairiness number of 3mm will showed increased, and then does the bar of yarn and the physical index such as powerful all has certain adverse effect.
Summary of the invention
Technical problem to be solved by this invention is the spinning method providing the embedded Compact-spun Yarn: of a kind of high count high-quality, can spin, can effectively reduce harmful hairiness number to filament yarn and staple fibre rove, improves spinning yarn quality.
For solving the problems of the technologies described above, the spinning method of the embedded Compact-spun Yarn: of high count high-quality of the present invention, comprise the following steps: two staple fibre rove are positioned over centre position, two threads yarns are distributed in the both sides of staple fibre rove respectively, four one threads are divided into two groups, often organize and comprise a staple fibre rove and a threads yarn respectively; When four kinds of yarns jaw horizontal line before drawing rollers, under the plane of twist triangle zone, downward air negative pressure is added in method phase direction; In twist triangle zone, a pair staple fibre rove, filament yarn are twisted, and twist another group staple fibre rove, filament yarn in twist triangle zone two; Twist triangle zone one and twist triangle zone two twist after semi-finished product yarn enter twist triangle zone three again, by the obtained finished yarn of ring-traveller twisting.
Described air negative pressure pressure limit is 0.15Mpa ~ 0.3Mpa.
In technique scheme, adopt negative pressure of vacuum method, in twist triangle zone one, the staple fibre not being subject to filament yarn constraint in staple fibre rove retrains, then fibre migration entered the trunk of yarn by the twisting effect of twist triangle zone three by these two regions, twist triangle zone two.Owing to have employed air negative pressure, the twisting efficiency of twist triangle zone improves, and the filoplume of yarn reduces further, because the yarn evenness phenomenon that filoplume causes will take a turn for the better on the basis that embedding is spun.Because fiber content in yarn trunk increases, by the total amount that can increase the frictional force between fiber during external force, add the raising of twisting efficiency, the twist of the prerequisite yarn under working of identical speed of spinning frame is higher, cohesive force between fiber is larger, thus adds the brute force of finished yarn from two aspects.

In figure: EE '---jaw horizontal line before drawing rollers; A, D---filament yarn; B, C---staple fibre rove; 1---twist triangle zone one; 2---twist triangle zone two; 3---twist triangle zone three.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention adopts embedded spinning mode, and staple fibre rove B and C is positioned over centre position, and two threads yarn A and D are distributed in the both sides of staple fibre rove respectively.When four kinds of yarns are before drawing rollers during jaw EE ', under the plane of twist triangle zone, downward air negative pressure is added in method phase direction, and the fiber of twist triangle zone cannot be moved freely by External Force Acting.Have employed this technical scheme to retrain not being subject to the staple fibre that filament yarn A retrains in staple fibre rove B in this region, twist triangle zone 1, then fibre migration is entered the trunk of yarn by the twisting effect of twist triangle zone.Retrain not being subject to the staple fibre that filament yarn D retrains in staple fibre rove C in this region, twist triangle zone 22, then fibre migration is entered the trunk of yarn by the twisting effect of twist triangle zone.Twist triangle zone 1 and twist triangle zone 22 twist after yarn enter twist triangle zone 33 again, this process part twist triangle zone 1 and twist triangle zone 22 can be twisted after yarn in stretch out yarn trunk filoplume shift into yarn trunk.
Embodiment one:
Select cotton rove and chinlon filament yarn as spinning material, raw material A, D are chinlon filament yarns, and B, C are cotton rove, and the air negative pressure pressure of applying is 0.15Mpa.The yarn test obtained after fine spining machine spinning the results are shown in Table 1.
Embodiment two:
Select cotton rove and chinlon filament yarn as spinning material, raw material A, D are chinlon filament yarns, and B, C are cotton rove, and the air negative pressure pressure of applying is 0.20Mpa.The yarn test obtained after fine spining machine spinning the results are shown in Table 1.
Embodiment three:
Select cotton rove and chinlon filament yarn as spinning material, raw material A, D are chinlon filament yarns, and B, C are cotton rove, and the air negative pressure pressure of applying is 0.25Mpa.The yarn test obtained after fine spining machine spinning the results are shown in Table 1.
By comparing discovery to the statistics of three kinds of embodiments, air negative pressure pressure is under the condition of 0.20Mpa, and the dry standard deviation of bar (CV%) of products obtained therefrom, hairiness index (H), powerful index reach ideal index.
Be different from conventional method, the present invention, to the little fiber of initial modulus and the large fiber of initial modulus, all has positive effect.
