All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Example 1

As shown in fig. 1-2, a flax polyester filament cross-twisted yarn comprises a core yarn and a skin yarn; the outer surface of the core yarn is spirally twisted with a skin yarn 1; the core yarn comprises a yarn core 2, and the outer surface of the yarn core 2 is sequentially and alternately spirally wound with cationic polyester yarns 3, viscose fiber yarns 4, elastic polyester fiber yarns 5 and flame-retardant cotton threads 6; the yarn core 2 is formed by twisting flax fiber yarns 21 and polyester filaments 22.

Specifically, the yarn core 2 formed by twisting the flax fiber yarn 21 and the polyester filament yarn 22 has the characteristics of high strength, moisture absorption, air permeability, low static electricity and the like by mixing the polyester and the flax. And due to the addition of the polyester filaments 22, the yarn core 2 has good structural stability, and is beneficial to winding the cationic polyester yarns 3, the viscose fiber yarns 4, the elastic polyester fiber yarns 5 and the flame-retardant cotton threads 6 on the outer surfaces of the yarns. The manufacturing process of the yarn core 2 in the embodiment of the utility model: the flax spinning frame is improved, and the filament yarn guide wheel is arranged on the cradle through a short shaft with threads and a positioning nut to realize the feeding and position adjustment of the polyester filament yarn, so that the polyester filament yarn and the flax roving keep a certain distance to be fed into a drafting zone, and the polyester filament yarn is prevented from being broken by drafting while being protected from being drafted; the gripping force of the rear roller jaw to the polyester filament yarn is increased to stretch the polyester filament yarn while the flax fiber yarn breaks, so that the timely breaking of the polyester filament yarn after the flax yarn breaks is realized when the flax and the polyester filament yarn are blended, the processing efficiency of spinning broken ends is improved, and the yarn core 2 is obtained.

Further, the winding of the yarns with different characteristics of the cationic polyester yarns 3, the viscose yarns 4, the elastic polyester yarns 5 and the flame-retardant cotton yarns 6 enables the core yarn to have dyeability, easy dyeing property, hygroscopicity, elasticity, flame retardance and the like. The core yarn designed in this way has the characteristics of good structural stability and high strength.

Still further, the cover yarn 1 is a flax fiber yarn. The flax fiber has a natural spindle-shaped structure and unique pectic inclined side holes, has the characteristics of excellent moisture absorption, ventilation, corrosion resistance, bacteriostasis, low static electricity and the like, and has good use touch feeling and moisture absorption and ventilation property by selecting flax fiber yarns as skin yarns. Further, the elastic polyester fiber yarn 23 is PTT fiber. The PTT fiber has the stability of terylene and the softness of chinlon, and the fiber structure of the PTT fiber is provided with a methylene group, so that the fiber is spiral, namely the PTT fiber has elasticity. Still further, the PTT fiber is impregnated with a uniform antibacterial solution, so that a layer of antibacterial agent is attached to the surface of the fiber, thereby giving the antibacterial effect to the yarn.
