Embodiment 1

[0015] Such as figure 1 As shown, an elastic core-spun yarn includes a core fiber 1 and an outer layer fiber 2, the outer layer fiber 2 wraps the core fiber 1 through a core-spun process, the core fiber 1 is spandex or other elastic fibers; the outer layer fiber 2 is aromatic Aramid staple fiber or polyethylene staple fiber, or a mixed fiber of aramid staple fiber and polyethylene staple fiber (in any proportion), or one of the two fibers containing aramid staple fiber and polyethylene staple fiber or Mixed fibers of two types of fibers and others.

[0016] The fineness of spandex or other elastic fibers is 2-2500D, and the draft ratio is 5%-500%.

[0017] The core-spun process is a production process in which the core fiber is introduced into the core fiber through the yarn guide device during the process of fiber being drawn under force and twisted at the same time, and the core fiber is wrapped in the outer fiber core. The twist degree of twisting is 20-1500 twists / m. Th...

Embodiment 2

[0029] Such as figure 2 As shown, a covered yarn of an elastic core-spun yarn, the covered yarn with the elastic core-spun yarn containing aramid fiber or high-strength high-modulus polyethylene (hppe) in Example 1 as the core. In addition to the characteristics of the core-spun yarn described in Example 1, the product also combines the diversity of covering processes to bring more style / performance advantages to the product.

[0030] The core core-spun yarn is the elastic core-spun yarn containing aramid fiber or high-strength high-modulus polyethylene (hppe) as described in Example 1.

[0031] The outer covering yarn is spun yarn or filament yarn with a thickness of 5-200tex, and the twist direction is S direction or Z direction.

[0032] The number of outer covering yarns is 1-5, and the twist directions are S direction or Z direction respectively.

Embodiment 3

[0034] Such as image 3 As shown, an elastic core-spun yarn is a twisted yarn comprising the elastic core-spun yarn of aramid fiber or high-strength high-modulus polyethylene (hppe) described in Example 1. In addition to the characteristics of the core-spun yarn described in Example 1, the product combines the characteristics of the two-for-one twisting process and the performance of other parallel yarns, bringing more style / performance advantages to the product.

[0035] A yarn is an elastic core-spun yarn containing aramid fiber or high-strength high-modulus polyethylene (hppe) described in embodiment 1, and the twist direction is S-direction or Z-direction

[0036] B yarn is the elastic core-spun yarn containing aramid fiber or high-strength high-modulus polyethylene (hppe) described in embodiment 1, or other short fiber yarns or filament yarns, and the twist direction is the same as the A yarn.

[0037] The twist direction of the plied yarn is opposite to that of A and B ...

Abstract

The invention discloses an elastic core-spun yarn comprising an outer fiber layer and a fiber core wrapped by a covering process. The fiber core is made of spandex or other elastic fibers; the outer fiber layer is made of aramid short fiber or polyethylene short fiber, or made of mixture of aramid short fiber and polyethylene short fiber in any proportion, or made of fiber mixture including aramid short fiber and polyethylene short fiber. The invention further discloses application of the elastic core-spun yarn in textiles. The elastic core-spun yarn has excellent properties, excellent protective performance, better elasticity, and better comfort and flexibility.

Description

technical field [0001] The invention relates to an elastic core-spun yarn and its application. Background technique [0002] Existing textiles made of aramid fiber or high-strength high-modulus polyethylene (hppe) yarns often feel stiff, poor in comfort, and inflexible in operation, resulting in discomfort for users and easy operation errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elastic core-spun yarn and its fabric, which can ensure a comfortable hand feeling under the premise of ensuring excellent cut resistance quality. [0004] The technical solution adopted by the present invention to solve its technical problems is: a kind of elastic core-spun yarn, comprising core fiber and outer layer short fiber, outer layer short fiber wrapping core fiber by core-spun process, (core fiber is spandex or other elastic fibers) fiber); the outer fiber is aramid staple fiber or polyethylene staple fiber, or is...
