Embodiment 1

[0052] The raw spandex fiber yarn used as the core yarn of the composite elastic yarn was produced by the following method. The high temperature in the spinning drum makes the raw spandex fiber in a heated state after spinning, which is suitable for causing the kink of the raw yarn and is drawn out. At this time, air is supplied through the first interlacing nozzle, and the adhesive force between the filaments of the original spandex fiber is 870 mg, which belongs to the range of the 80D general spandex fiber adhesion value. After that, the bonding force between the filaments of the original spandex fiber yarn was measured as 5% of the bonding force value of 800 mg of the general spandex fiber of 80D by imparting low temperature and low pressure air through the second air interlacing nozzle during the crimping process. of 40mg.

[0053] As the hard yarn, cotton yarn with a count of 16 is used, and the low-adhesion elastic core yarn produced above is used as the core yarn. Th...

Embodiment 2

[0057] The core yarn of the composite elastic yarn used in the manufacture of denim fabrics is suitable for elastic yarns with low adhesion between filaments. At this time, the adhesive force between the filaments of the spandex fiber raw yarn after passing through the first interlacing nozzle is 880 mg, which belongs to the range of the 80D general spandex fiber adhesion value. After passing through the second air interlacing nozzle, the spandex fiber raw yarn is The inter-filament adhesion was measured to be 14 mg as 2% of the adhesion value of 700 mg of 80D general-purpose spandex fiber.

[0058] The composite elastic yarn and fabric were produced in the same manner as in Example 1 except that the core yarn was different as described above, and the physical properties were evaluated and the results are shown in Table 1.

Embodiment 3

[0060] The core yarn of the composite elastic yarn used in the manufacture of denim fabrics is suitable for elastic yarns with low adhesion between filaments. At this time, the adhesive force between the filaments of the spandex fiber raw yarn after passing through the first interlacing nozzle is 870 mg, which belongs to the range of the 80D general spandex fiber adhesion value. After passing through the second air interlacing nozzle, the spandex fiber raw yarn is The inter-filament adhesion was measured to be 198 mg which is 22% of the adhesion value of 900 mg of 80D general purpose spandex fiber.

[0061] The composite elastic yarn and fabric were produced in the same manner as in Example 1 except that the core yarn was different as described above, and the physical properties were evaluated and the results are shown in Table 1.

Abstract

Disclosed are a composite elastic yarn, a fabric, and a method for manufacturing the composite elastic yarn, the composite elastic yarn comprising a core part consisting of an elastic core yarn and a sheath part consisting of short fibers wrapping the core part, where the elastic core yarn has a low adhesion property in which an adhesion force between filaments is in the range of 9 to 198 mg when measured according to the ASTM D3822 method, and the composite elastic yarn has a low adhesion property in which the adhesion force between filaments is in the range of 9 to 198 mg when measured according to the ASTM D3822 method. According to the present invention, the problem of wrinkling occurring on the surface of the fabric for denim can be solved, thereby improving the tactile sensation and improving the quality of the final product.

Description

technical field [0001] The invention discloses a composite elastic yarn, a stretchable fabric and a manufacturing method of the composite elastic yarn. More specifically, the core yarn of the composite elastic yarn uses a low-bond elastic yarn with low adhesion between filaments to solve the problem of fabrics. Puckering problem in morphology. Background technique [0002] The stretchable fabric used for denim is woven into a composite elastic yarn with Spandex as the core yarn. The composite elastic yarn consists of a core section and a sheath section covering the core. Generally, the core yarn of the in-fabric composite elastic yarn used for denim uses a single-core or double-core elastic yarn to impart stretchability to the denim fabric. Single-core means that the core yarn is suitable for one bundle of elastic yarn, and double-core means that the core yarn is suitable for two bundles of elastic yarn and polyester binary fiber. [0003] As an example, US Pat. No. 8,093...
