Abstract

The invention provides a machining method of a wrapped structural flax and polyester filament section color composite yarn and a composite yarn. A section color effect principle of fusing and twistingtwo yarns with different colors, a specific false twisting effect of core yarns when a hollow ingot is subjected to wrap spinning of an externally-wrapped yarn and the core yarns are wound, a twist instability principle of the specific false twisting effect and an uneven distribution principle of a twist on a plucked yarn are comprehensively utilized; by enabling double core yarns to generate anirregular section color effect and adopting the colorless excellent-transparency filament (monofilament or less-number multifilament) externally-wrapped yarn to carry out wrapping consolidation, the flax composite yarn with section color characteristics is obtained. Wrinkle resistance of flax fabric can be effectively improved, yarn hairiness is reduced, hairiness regeneration is reduced, weavability is improved, section color appearance is given to the yarn and the fabric thereof, and the fabric is woven in a dyeing-free and sizing-free mode.

Description

technical field

[0001] The invention relates to the field of processing fancy and colored flax composite yarns, in particular to a processing method for wrapping structured flax and polyester filament segment-color composite yarns and the composite yarn. Background technique

[0002] Flax fiber is a kind of biomass fiber (natural cellulose fiber), and also a kind of rare natural fiber, its output only accounts for about 1.5% of the total amount of natural fibers. Flax fiber textiles have good coolness, crispness and cleanliness, and have good air permeability and moisture permeability, mildew resistance, insect resistance, anti-ultraviolet, anti-static and other excellent properties and functions, which are not available in other natural fibers. And it is irreplaceable, not to mention unmatched by chemical fibers.

[0003] However, the inherent defects of hemp fiber, such as high rigidity, poor elasticity, and poor dyeability, lead to poor textile processing performance and...

Examples

Embodiment

[0092] The linen core yarn used is 36Nm wet-process long-linen bleached linen yarn, and its yarn blackboard is as follows: Figure 4 and Figure 5 shown. It can be seen from the figure that the yarn has obvious uneven thickness characteristics (evenness unevenness is 35.65%, -50% details reach 3791.7 pieces / km, 400% thick places reach 140 pieces / km), and the yarn hairiness is more (The hairiness value H reaches 2.45mm / cm).

[0093] The specification of the polyester core yarn used is 150D / 48F, and the variety is FDY. Red, blue, green three colors and flax yarn are respectively used to form double-core yarn for wrapping processing.

[0094] The wrapping yarn is polyester monofilament with a diameter of 0.08mm and a linear density of 69dtex.

[0095] The main process is: the hollow spindle speed is 15435r / min, the yarn drawing speed is 28m / min, the wrapping twist is 551 twists / m, and the wrapping twist is S twist.

[0096] The appearance of the spun composite yarn is as fol...
