Embodiment 1

[0029] A quick-drying flame-retardant arc-proof core-spun yarn, the core-spun yarn includes a core layer 1 and a skin layer 2, the skin layer 2 is coated on the outside of the core layer 1; the core layer 1 is made of flame-retardant filaments fibers or flame-retardant and non-hygroscopic spun yarns, and the skin layer 2 is composed of flame-retardant polyimide fibers, flame-retardant viscose fibers, flame-retardant acrylic fibers, and wool fiber blends; the cross-sectional area of ​​the core layer 1 occupies 10%-50% of the cross-sectional area of ​​the core yarn; the skin layer 2 is evenly mixed with flame-retardant polyimide fiber, flame-retardant viscose fiber, flame-retardant acrylic fiber and wool fiber and coated on the core layer through the spinning process 1 obtained from outside; the mass ratio of flame-retardant viscose fiber in the skin layer 2 is: 10-50 parts; the mass ratio of flame-retardant acrylic fiber in the skin layer 2 is: 10-60 parts; The mass ratio of fl...

Embodiment 2

[0031] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0032] The cross-sectional area of ​​the core layer 1 accounts for 10% of the cross-sectional area of ​​the core-spun yarn.

[0033] The mass ratio of the flame-retardant viscose fiber in the cortex 2 is: 40 parts; the mass ratio of the flame-retardant acrylic fiber in the cortex 2 is: 25 parts; the mass ratio of the flame-retardant polyimide fiber in the cortex 2 The mass part ratio is: 30 parts; the mass part ratio of the wool fiber in the cortex 2 is: 5 parts.

[0034] The material of the core layer 1 can be composed of any one of polyimide staple fiber, flame-retardant polyester staple fiber, and flame-retardant polypropylene staple fiber.

Embodiment 3

[0036] Embodiment 3 is basically the same as Embodiment 1, and its difference is:

[0037] The cross-sectional area of ​​the core layer 1 accounts for 20% of the cross-sectional area of ​​the core-spun yarn.

[0038] The mass ratio of the flame-retardant viscose fiber in the cortex 2 is: 50 parts; the mass ratio of the flame-retardant acrylic fiber in the cortex 2 is: 10 parts; the mass ratio of the flame-retardant polyimide fiber in the cortex 2 The mass ratio is: 50 parts; the mass ratio of the wool fiber in the cortex 2 is: 1 part.

[0039] The material of the core layer 1 can be composed of any one of polyimide staple fiber, flame-retardant polyester staple fiber, and flame-retardant polypropylene staple fiber.

Abstract

A quick-drying flame-retardant arc protection core-spun yarn comprises a core layer and a skin layer. The skin layer coats the outside of the core layer, the core layer comprises flame-retardant filament fibers or flame-retardant non-hygroscopic staple fiber yarns, the skin layer comprises flame-retardant polyimide fibers, flame-retardant viscose fibers, flame-retardant acrylic fibers and wool fibers by blending, and the sectional area of the core layer accounts for 10%-50% of that of the core-spun yarn. The core-spun yarn has flame resistance, and a fabric woven with the core-spun yarn has skin-friendly and quick-drying properties.

Description

technical field [0001] The invention relates to a fast-drying flame-retardant arc-proof core-spun yarn, which is particularly suitable for making flame-retardant fabrics have quick-drying and skin-friendly properties. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. New bead thread with polyester coated polyester cored thread. [0003] Anti-flame retardant fabric is flame retardant fabric, which is a special fabric that can delay flame burning. Anti-flame retardant fabrics are divided into finishing flame retardant and raw material yarn flame retardant. Existing flame-retardant fabrics generally have the problems of being not skin-friendly, airtight, and difficult to dry in a short time. Contents of the invention [0004] The...
