Abstract

The invention provides a soft core yarn and a preparation method. The soft core yarn comprises a core yarn and an outer layer fiber, and the outer layer fiber wraps the core yarn; and the twist of thecore yarn is lower than that of the outer layer fiber. Compared with the prior art that long stapled cotton and cotton fiber are blended, the soft core yarn composed of cotton fiber and long stapledcotton is low in cost and high in cost performance; and yarns produced by the spinning process are high in single yarn strength, less in hairiness, uniform in evenness, less in neps and less in yarn faults. The yarn structure can further improve the comfort of the fabric, improve the hand feeling of the fabric and improve the grade of the fabric.

Description

technical field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a soft core yarn and a preparation method thereof. Background technique

[0002] With the improvement of people's living standards and the change of the concept of textiles. Yarns with environmental protection, antibacterial, deodorant, moisture absorption and perspiration functions are favored by the market.

[0003] However, the textile technology is still not up to market requirements, so it is urgent to research and develop new products to meet the new market demand for textiles. Contents of the invention

[0004] Aiming at the above-mentioned deficiencies of the prior art, the present invention provides a flexible core yarn and a preparation method to solve the above-mentioned technical problems.

[0005] The embodiment of the present application provides a flexible core yarn, the flexible core yarn includes a core yarn and outer layer fibers, the outer laye...

Examples

Embodiment 1

[0029] This embodiment provides a kind of flexible core yarn, a kind of short fiber is covered with a kind of short fiber, wherein one kind of fiber is the core, another kind of fiber is the sheath, the inside core yarn is twisted in the opposite direction to the outer short fiber, during the twisting process In the process, the twist of the core yarn is reduced, and it is close to the untwisted state, so that the core yarn forms a nearly smooth fiber bundle, making the yarn softer. The content of the core yarn is 1-30%, and the balance is the sheath (outsourcing). The core yarn fiber is made of high-quality long-staple cotton.

Embodiment 2

[0031] The present embodiment provides a kind of flexible core yarn preparation method, comprises the following steps:

[0032] Process flow: 1. Core yarn: FA002A automatic plucking machine → FA103 mixed opener → FA022 multi-compartment mixed machine → FA106 opener → FA046 vibrating box feeder → A076F single beater roll Machine → FA201B carding machine → FA305 drawing frame (pre-drawing) → A191B sliver coiler → A201E combing machine → FA317A mixing → FA317A finishing → FA415A roving frame → FA506S spinning frame → NO.21C automatic winder.

[0033] 2. Soft core yarn: FA002A automatic plucking machine → FA103 mixed opener → FA022 multi-compartment blender → FA106 opener → FA046 vibrating cotton box feeder → A076F single hand coiler → FA201B carding machine → FA317A mixing → FA317A finishing → FA415A roving frame → FA506S spinning frame + core yarn plying → NO.21C automatic winding.
