Description

High-elasticity lycra yarn

Technical Field

The utility model relates to a fancy yarn, concretely relates to high elasticity lycra fancy yarn.

Background

The lycra yarn is a trade name of an artificial elastic spandex fiber produced by DuPont exclusive invention, is polyester spandex produced by dry spinning, and consists of a flexible chain segment and a rigid chain segment. However, the conventional lycra yarn has the problems of insufficient flexibility and air permeability.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a high-elasticity lycra fancy yarn which has reasonable structural design, beautiful appearance, softness, comfort, dryness and ventilation.

The utility model provides a technical scheme that above-mentioned problem adopted is: the high-elasticity lycra yarn comprises a core yarn, elastic filaments and colored filaments; the core yarn is twisted with a plurality of colored filaments to form a core-spun yarn structure; the core yarn comprises a tubular outer structure and an inner structure nested in the outer structure; four cavities are formed between the inner layer structure and the outer layer structure; 2-3 elastic filaments are inserted into any cavity.

Preferably, the core yarn in the utility model is lycra fiber; the elastic filament is a spandex filament; the colored filament is dyed chinlon filament.

Preferably, the linear density of the spandex filament in the present invention is 40D.

Preferably, in the utility model, the number of the core yarn is smaller than that of the colored filament; the number of the colored filaments is less than the number of the elastic filaments.

Preferably, in the present invention, the outer contour line of the cross section of the inner layer structure is a rhombus formed by four lines connected end to end.

Preferably, in the present invention, the outer contour line of the cross section of the inner layer structure is an arc line.

Preferably, the four cavities in the present invention are the same in size and shape.

Compared with the prior art, the utility model, have following advantage and effect: the utility model has reasonable structure design, beautiful appearance, excellent elasticity and strength; the utility model has the advantages that the elastic filaments are inserted into the hollow cavity in the Lycra fiber to form a ventilation channel in the fiber, thereby greatly increasing the ventilation performance of the Lycra fiber; the utility model twists the core yarn and the colored nylon filament yarn to form the structure of the core-spun yarn, the colored nylon filament yarn can provide various colors for the yarn, the aesthetic degree of the yarn is enhanced, and the colored nylon filament yarn has good moisture absorption and wear resistance, and can effectively enhance the strength of the yarn; the utility model provides a colored filament count is higher, and the winding enables the yarn more soft comfortable on the core yarn.

Drawings

Fig. 1 is a schematic structural view of a highly elastic lycra yarn in an embodiment of the present invention.

Fig. 2 is a schematic structural view of a core yarn in an embodiment of the present invention.

In the figure: the core yarn comprises a core yarn 1, an elastic filament 2, a colored filament 3, an outer layer structure 11, an inner layer structure 12 and a cavity 13.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

Referring to fig. 1 to 2, the high elastic lycra yarn in the present embodiment includes a core yarn 1, elastic filaments 2, and colored filaments 3; the core yarn 1 and a plurality of colored filaments 3 are twisted to form a core-spun yarn structure; the core yarn 1 comprises a tubular outer structure 11 and an inner structure 12 nested in the outer structure 11; four cavities 13 are formed between the inner layer structure 11 and the outer layer structure 12; 2-3 elastic filaments 2 are inserted into any one cavity 11.

The core yarn 1 in this example is lycra fiber; the elastic filament 2 is a spandex filament; the colored filament 3 is a dyed chinlon filament; the linear density of the spandex filament is 40D; the number of the core yarn 1 is smaller than that of the colored filament 3; the number of the colored filaments 3 is smaller than the number of the elastic filaments 2.

The outer contour line of the cross section of the inner layer structure 12 in this embodiment is a rhombus formed by four lines connected end to end; the outer contour lines of the cross section of the inner layer structure 12 are all arc lines; the four cavities 13 are all the same size and shape.

In the embodiment, the elastic filaments 2 are inserted into the hollow cavity in the Lycra fiber to form an air-permeable channel in the fiber, so that the air permeability of the Lycra fiber is greatly improved; in the embodiment, the core yarn 1 and the colored filament 3 are twisted to form the structure of the core-spun yarn, the colored filament 3 can provide various colors for the yarn, the attractiveness of the yarn is enhanced, and the colored filament 3 has good moisture absorption and wear resistance and can effectively enhance the strength of the yarn; the colored filaments 3 have a higher count and are wound around the core yarn 1 to make the yarn softer and more comfortable.

In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention. All the equivalent changes or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
