Structure, three rollers successively include front roller, middle roller, rear roller from front to back；In use, being wrapped using made from the 4th step
Core rove presses feeding drafting system by rear roller, under the drawing-off effect of drafting system, being in the cored rove of feeding
The viscose staple fibre of bending state, the first polyester staple fiber, the second polyester staple fiber be stretched stretch and if stretched after
It also continues being acted on by drawing-off and mutual phorogenesis then occurs, viscose staple fibre, the first terylene in straight configuration
Staple fiber, the second polyester staple fiber, which are stretched, occurs mutual phorogenesis, so that glue/washing in cored rove is mixed
Conjunction rove generation stretches the effect that attenuates and is glued/washed mixing yarn, while the third terylene under drawing-off effect in cored rove
Endless tow is pulled off into the third polyester staple fiber being distributed with certain length, and returning due to breaked third polyester fiber
Bullet effect distribution glue/washs mixing yarn after attenuating so that the third polyester staple fiber obtained after breaking is randomly distributed over to stretch
It is interior, at the same glue/wash the first polyester staple fiber in mixing rove, staple fiber long in the second polyester staple fiber continues to be pulled off,
And be randomly distributed under the distribution of breaked rebound effect and stretch glue/washing in mixing yarn after attenuating, it then obtains most
It is required eventually glue/to wash compound yarn, compound yarn glue/is washed through front roller pressing and exports drafting system, is then twisting the twist
Lower viscose staple fibre, the first polyester staple fiber, the second polyester staple fiber, the third terylene short fiber glue/washed in compound yarn of effect
Dimension occurs transfer and the composite blended yarn with certain strength is then made so that mutually entwining between fiber, and in twisting process
In, glue/wash viscose staple fibre in compound yarn, the first polyester staple fiber, the second polyester staple fiber, third polyester staple fiber
Mutual immixture is realized in transfer.
