It is better, but composite yarn can lose the style and features of part line.The line density of dacron thread is selected to be not more than linen thread and yarn density
50%, ensure composite yarn in flax content be not less than 70%.
（4）The color of composite yarn controls.After the color for determining color polyester network yarn, the shade of composite yarn mainly leads to
The line density and the looping twist for crossing color polyester network yarn are adjusted, and the line density of color polyester network yarn is bigger, and looping is twisted
Degree is bigger, and the color of composite yarn is deeper.The looping twist is bigger, and the segmentation of yarn color lump is more careful, and color blending effect is better.
（5）Line tension force.Due to line poor flexibility, tension fluctuation is larger during unwinding feeding, causes
The larger fluctuation of flax yarn tension influences stablizing for looping and carries out, because of heart yarn tension fluctuation, can cause heart yarn and outer fasciated yarn
The continuous variation of plotted point, when heart yarn tension is small, under outer fasciated yarn tension force effect, plotted point can deviate twizzle, at this time
Heart yarn and outer fasciated yarn, which are formed, hands over twirl rather than looping.If tension is too small, in hollow ingot top heart yarn and outer fasciated yarn plotted point

With three guide posts, line bypasses three guide posts successively, you can reduces tension fluctuation.Spring tensioner is adjusted, heart yarn is made
It is stably held at twizzle with the plotted point of outer fasciated yarn, overtension, also results in heart yarn broken end.
（6）The cooperation of outer fasciated yarn looping twist direction and flax heart yarn twist direction.Line passes through hollow ingot during feeding
Central tube is inevitably generated false twist effect by the friction of central tube bottom end and pore inner wall, if false twisting twist direction with
Line twist direction causes Yarn break to increase on the contrary, the backtwisting of line can be caused.For this purpose, the looping twist direction of outer fasciated yarn is answered
It is identical as line twist direction, at this point, the revolution of hollow ingot central tube is consistent with the original twist direction of line to the false twisting twist direction of line,
It will not cause backtwisting, the broken end of line.I.e. if flax heart yarn is twisted for Z, looping twist direction also should be that Z is twisted.
