In the figure: the composite material comprises an outer layer 1, an intermediate layer 2, single fibers 21, a fiber group 22, superfine denier fibers 221 and a core layer 3.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the composite yarn comprises a core layer 3, a middle layer 2 and an outer layer 1 which are sequentially arranged from inside to outside, wherein the core layer 3 is arranged at the center of the yarn, the middle layer 2 surrounds the periphery of the core layer 3, and the outer layer 1 is wrapped on the outer side of the middle layer 2.
The core layer 3 comprises a plurality of core yarns, the core yarns are nylon 6, the breaking strength of the nylon filaments is highest in common fibers and is about 3.528-5.292N/dtex, meanwhile, the resilience of the nylon filaments is highest, and when the nylon filaments extend for 3%, the resilience rate of the nylon 6 is 100%, so that the nylon 6 serves as the core yarns, and the breaking strength and the resilience of the composite yarns can be greatly improved. The initial modulus of the chinlon is close to that of wool, so that the chinlon feels soft, and the obtained yarns have soft hand feeling after being plied with the middle layer yarns and the outer layer yarns.
The core yarns are in low-twist doubling, the low-twist doubling has better effect of preventing the core yarns from being hooked than a straight core structure without the low-twist doubling, and due to twisting and doubling, cohesive force among the core yarns is improved, the shape is more stable, and fluffing is not easy to occur; and the effective component force is not reduced by the low twist, so the strength of the core layer 3 is not affected.
