The utility model discloses further set up to: the fineness of the MOY white yarn is 15-20D, the fineness of the MOY color yarn is 10-15D, and the fineness of the POY white yarn (4) is 2-3D.

By adopting the technical scheme, the manufactured double-color polyester yarn has moderate titer on the basis of meeting the strength, and is suitable for being used as a super indigo denim warp yarn. MOY look silk surface twists with there is the thinner POY white silk of fibre number, has improved the smoothness on double-colored dacron silk surface, and the sense of touch is better the utility model discloses further set up to: the fineness of the core bamboo fiber is 20-25D.

Through adopting above-mentioned technical scheme, MOY white silk and MOY look silk can laminate and distribute in the outside of core bamboo fiber silk, and the clearance between each line of whole double-colored dacron silk is moderate, has certain gas permeability under the condition of guarantee fibre number.

To sum up, the utility model discloses compare and have following beneficial effect in prior art:

1. the strength and the wear resistance of the whole double-color polyester yarn are improved by twisting the outer layer bamboo fiber yarn on the surface of the colored yarn, so that the super indigo jean is favorably manufactured;

and 2, POY white yarns with thinner titer are twisted on the surface of the MOY colored yarns, so that the smoothness of the surface of the bicolor polyester yarns is improved, and the touch feeling is better.

Detailed Description

A DTY double-color polyester yarn for denim warp yarns is shown in figure 1 and comprises core bamboo fiber yarns 5, MOY white yarns 1 and MOY color yarns 2, wherein the number of the MOY white yarns 1 and the number of the MOY color yarns 2 are respectively 3, and the MOY white yarns 1 and the MOY color yarns 2 are wound outside the core bamboo fiber yarns 5 alternately.

The core bamboo filament 5 is filled with nanometer tourmaline particles 6, and the particle diameter of the nanometer tourmaline particles 6 can be 10-20 nm. The filling method may be as follows: the bamboo fiber filament 5 at the core part is soaked in the solution mixed with the nano tourmaline particles 6, and because the bamboo fiber has countless fine grooves on the surface, the interior is hollow, and the bamboo fiber has instant water absorption, the solution mixed with the nano tourmaline particles 6 can be absorbed into the tissue, and then the bamboo fiber filament is dried, so that the nano tourmaline particles 6 are remained and attached to the bamboo fiber filament 5 at the core part.

In order to improve the wear resistance of the MOY colored filament 2, an outer layer bamboo fiber filament 3 is wound outside the MOY colored filament 2. There are 6 outer layer bamboo cellosilk 3 here, in order to practice thrift outer layer bamboo cellosilk 3 quantity, can increase 6 POY white silks 4 and twist in turn and wind outside MOY colored silk 2 together. According to the requirement, the interior of the outer layer bamboo fiber 3 can be filled with nanometer tourmaline particles 6.

According to the needs, nanometer silicon dioxide is adsorbed in the MOY white yarns 1 and the POY white yarns 4, so that after the two-color polyester yarns are made, the polyester yarns can be immersed in tannin solution, the nanometer silicon dioxide has a huge specific surface area, a surface multi-mesoporous structure and super-strong adsorption capacity, and tannin is adsorbed in the MOY white yarns 1 and the POY white yarns 4, so that the manufactured two-color polyester yarns have a remarkable inhibition effect on bacteria, and the woven clothes are high in antibacterial property and particularly suitable for weaving children clothes.

The MOY white yarn 1 can be formed by twisting 5-8 strands of single yarns, and the fineness is 15-20D. The MOY colored filament 2 can be formed by twisting 4-6 strands of single yarns, and the titer is 10-15D. The core bamboo filament 5 can be formed by twisting two bamboo fibers, and the fineness is 20-25D. The fineness of the outer layer bamboo fiber 3 is 2-3D, and the fineness of the POY white yarn 4 can be 2.5-3.0D.

The production method of the DTY double-color polyester yarn for the denim warp yarn comprises the following steps:

the bamboo fiber 5 at the core part is immersed into the solution mixed with the nano tourmaline particles 6, and then taken out and naturally dried.

The MOY white yarn 1 and the POY white yarn 4 were dipped together into a solution mixed with nano silica, and then taken out to be dried.

6 POY white filaments 4 and 6 outer layer bamboo fiber filaments 3 are twisted together by taking the MOY colored filament 2 as the center. And twisting the 3 stranded silk yarns and the 3 MOY white yarns 1 together by taking the core bamboo fiber yarn 5 as the center.

And finally, soaking the prepared two-color polyester yarn into a tannin solution, taking out and drying.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
