Embodiment 1

[0033] The high-performance composite yarn of this embodiment combines figure 1 , including twisted covered yarn 1 and twistless core yarn 2, covered yarn 1 is wound on the outer layer of core yarn 2 in a twistless and combined manner, and there are network points 3 on the composite yarn, and the twist of the network point 3 and covered yarn 1 ( figure 1 The twist distance d) is the same, which is used to enhance the cohesion of the composite yarn. Among them, the reinforcing fiber is basalt fiber with a fineness of 330tex; the matrix fiber is polypropylene with a fineness of 100tex; the mass ratio of the reinforcing fiber to the matrix fiber is 3.3:1. Combine two fibers without twist, where:

[0034] (1) Mixing 0.3 parts by mass of matrix fiber with 3.3 parts by mass of reinforcing fiber, the mixing method is twistless and combined, evenly mixed to form a twistless core yarn;

[0035] (2) Twisting the remaining 0.7 parts of the base fiber to form a twisted wrapped yarn, th...

Embodiment 2

[0045] In the composite yarn prepared in this embodiment, the wrapped yarn 1 is polypropylene, that is, the base fiber is polypropylene, the fineness of polypropylene fiber is 100tex, the reinforcing fiber is glass fiber, and the fineness of glass fiber is 270tex. The mass ratio of glass fiber to polypropylene fiber is It is 2.7:1, the two fibers are combined without twisting, where:

[0046] (1) Mixing 0.25 parts by mass of matrix fiber with 2.7 parts by mass of reinforcing fiber, the mixing method is untwisted and combined, evenly mixed to form a twistless core yarn;

[0047] (2) Twisting the remaining 0.75 parts of the matrix fiber to form a twisted wrapped yarn, the twist of the wrapped yarn is 50 twists / 10cm, and the twist direction is Z-shaped;

[0048] (3) Utilize the processing method of air-jet network, control the air-jet pressure to 0.24MPa, and the upper machine tension to 0.27N, entangle the two kinds of monofilaments with each other to form a glass / polypropylene ...

Abstract

The invention relates to a method for preparing high-performance composite yarn, which belongs to the technical field of special yarn preparation. It includes three steps of core yarn spinning, covering yarn spinning and composite yarn preparation, wherein the covering yarn is composed of matrix fiber, the matrix fiber is polypropylene fiber, the core yarn is composed of matrix fiber and reinforcing fiber, and the reinforcing fiber is basalt fiber, A mixture of one or more of glass fiber, aramid or polyethylene. The high-performance composite yarn obtained by the preparation method of the present invention overcomes the defect of poor mechanical properties of a single fiber. The surface of the composite yarn is smooth and has less hairiness. Excellent performance that single fiber does not have.

Description

technical field [0001] The invention relates to a method for manufacturing high-performance composite yarn, which belongs to the technical field of special yarn preparation. Background technique [0002] With the advancement of science and technology, new materials for industrial textiles are constantly showing development trends, and their uses are also expanding to various fields. The development of science and technology has promoted the renewal and progress of materials, and new materials are the key to the development of high-tech fields. Especially in the field of textiles, the material requirements are getting more and more attention. [0003] Two-dimensional or three-dimensional, unidirectional or multi-directional textile prefabricated parts can be prepared by weaving, knitting or weaving composite yarns, which can produce high-performance composite structural materials. Made of thermoplastic composite structural material, it has high toughness, good impact resist...
