High-elastic wear-resistant antibacterial regenerated polyester core-spun yarn and production process thereof

Abstract

The invention discloses a high-elastic wear-resistant antibacterial regenerated polyester core-spun yarn and a production process thereof, and particularly relates to the technical field of polyestercore-spun yarns. The core-spun yarn comprises a polyester core-spun yarn A and a polyester core-spun yarn B. The polyester core-spun yarn A comprises boron fibers, carbon fibers and basalt fibers; andthe polyester core-spun yarns B take polyimide filaments as core yarns and take polyester staple fibers as covering yarns. The boron fibers, the carbon fibers and the basalt fibers are used in cooperation, so that the heat resistance and the flame retardance of the polyester core-spun yarn can be effectively enhanced, heat insulation and flame retardance treatment can be effectively conducted atthe sewing position of a garment fabric, and the safety performance is improved. A carbon fiber yarn made of the polyester core-spun yarn A material and polyester staple fibers in the polyester core-spun yarn B are matched to be used as covered yarns, and a composite bulked yarn made of the polyester core-spun yarn A material and polyimide filaments in the polyester core-spun yarn B are matched tobe used as core yarns, so that the heat-resistant strength and the flame retardant property of the polyester core-spun yarn can be further improved, and the safety performance is improved.

Description

technical field

[0001] The invention relates to the technical field of polyester cored wire, more specifically, the invention relates to a regenerated polyester cored wire with high elasticity, wear resistance and antibacterial properties and a production process thereof. Background technique

[0002] Polyester core-spun yarn is produced by twisting and refining polyester staple fiber covered polyester staple fiber material, which has the appearance of polyester staple fiber and the function of low shrinkage. Polyester core-spun wire has the following characteristics: the same thickness provides higher strength (high strength); yarn count is more uniform, tensile force and other physical properties are more stable; higher constant elongation, or tensile strength Helps to better form loops and reduce sewing wrinkles; better plying safety - less loose thread breakage, very good wear resistance and durability; therefore polyester core-spun threads are popular in the apparel ind...

Examples

Embodiment 1

[0027] The invention provides a regenerated polyester core-spun yarn with high elasticity, wear resistance and antibacterial properties, which includes a polyester core-spun yarn A and a polyester core-spun yarn B. The polyester core-spun yarn A is calculated according to the weight percentage, and the polyester core-spun yarn A includes: 5.60 Boron fiber, 12.8% carbon fiber, and the rest are basalt fiber; polyester core-spun yarn B uses polyimide filament as the core filament, and polyester staple fiber as the covering filament;

[0028] The present invention also provides a preparation method of high elastic wear-resistant antibacterial regenerated polyester cored wire, the specific preparation steps are as follows:

[0029] Step 1: raw material selection: weigh boron fiber, carbon fiber and basalt fiber according to the above weight percentage;

[0030] Step 2: Primary twisting: basalt fiber yarn formed by twisting and plying 5 to 8 basalt fiber precursors;

[0031] Step 3...

Embodiment 2

[0040] Different from Example 1, the polyester core-spun yarn A includes: 7.40% boron fiber, 15.6% carbon fiber, and the rest is basalt fiber.

Embodiment 3

[0042] The difference from Examples 1-2 is that the polyester core-spun yarn A includes: 6.50% boron fibers, 14.7% carbon fibers, and the rest are basalt fibers.

[0043]Take the high-elastic wear-resistant antibacterial regenerated polyester cored thread prepared in the above-mentioned embodiments 1-3 and the polyester cored thread of the control group, the second polyester cored thread of the control group, the three polyester cored threads of the control group and the four polyester cored threads of the control group. Polyester cored thread, the first polyester cored thread of the control group is the common polyester cored thread on the market, the second polyester cored thread of the control group has no boron fiber compared with the embodiment, and the three polyester cored thread of the control group is compared with the embodiment No carbon fiber, the four polyester cored wires of the control group have no basalt limit compared with the examples, and are divided into se...
