Embodiment 1

[0021] In the prior art, the chemical fibers used in imitation natural hair products or wig products have the advantages of cheap price and high durability of styling, but have the disadvantages of obvious difference in visual perception from natural hair and poor fidelity.

[0022] In order to solve the technical problem of poor visual fidelity of chemical fibers used in imitation natural hair products or wig products, Example 1 provides a composite monofilament with a surface imitating scales, including: the core layer has an intrinsic viscosity of 0.76 to 0.92 dL / g PET, the skin layer is obtained from a blend of PET with an intrinsic viscosity of 0.6-0.68dL / g and cationic modified PET through alkali reduction treatment; the skin layer covers the core layer; the surface layer of the scale-like composite monofilament is Discretely distributed concave holes, the scale-like composite monofilament has a fineness of 6-85dtex, a strength of 5.2-8.6CN / dtex, and a rigid modulus of 21...

Embodiment 2

[0034] Embodiment 2 provides a method for preparing the surface imitation scale-like composite monofilament of embodiment 1, including the following steps, and the corresponding flow chart of some steps is as follows: figure 1 Shown:

[0035] In the step of preparing the raw material for the cortex (step S1), PET with an intrinsic viscosity of 0.6-0.68 dL / g and cationic-modified PET are blended by twin-screws and then granulated to obtain PET with an intrinsic viscosity of 0.6-0.68 dL / g and cationic-modified PET. Blends of PET;

[0036] In the step of preparing monofilaments of the skin and core layer (step S2), the core layer is selected from PET with an intrinsic viscosity of 0.76 to 0.92 dL / g, and the skin layer is selected from a blend of PET with an intrinsic viscosity of 0.6 to 0.68 dL / g and cationic modified PET. Melting, compound forming, stretching and setting treatment to obtain monofilament of skin core layer;

[0037] Alkali weight reduction treatment step (step ...

Embodiment 3

[0052] In the prior art, imitating natural hair is usually made of more expensive biological materials. Embodiment 3 provides an imitating natural hair, at least partially using the surface-imitating scale-like composite monofilament of embodiment 1. The imitation of natural hair provided in Example 3 uses a surface-imitation scale-like composite monofilament, and adopts cheap and easy-to-obtain raw materials and production equipment, which can realize mass production and reduce production costs. The imitation natural hair provided by Example 3 can produce a special luster similar to the imitation scale vision of natural hair due to the surface-imitation scale-like composite monofilament, which meets the modeling process requirements and use requirements of various imitation natural hairs, and has a broad market Prospect and use value.

Abstract

The invention relates to the field of fibers, and provides a surface scale-like composite monofilament and a preparation method and application thereof in order to solve the technical problem that fibers imitating natural hair are poor in visual fidelity. The surface scale-like composite monofilament comprises a core layer and a surface layer, wherein the core layer is made of high-viscosity PET,and the surface layer is obtained through alkali de-weighting of a mixture of conventional PET and cationic modified PET. The surface layer of the surface scale-like composite monofilament is in a dispersed concave hole shape, the fineness is 6-85 dtex, the strength is 5.2-8.6 CN/dtex, and the rigid modulus is 210-250 CN/dtex. Due to dispersed distribution of concave holes, the refractive index ofthe surface of the surface scale-like composite monofilament exhibits a multi-dimensional difference, has a special gloss sense similar to the scale-like vision of natural hair, has little differenceto visual perception of the natural hair, and is more visually vivid. The surface scale-like composite monofilament has excellent physical properties, is not prone to generating static electricity, easy to take care of and free of toxins and odors, and can meet various natural-hair-imitating modeling process requirements and usage requirements.

Description

technical field [0001] The invention relates to the field of fibers, in particular to a scale-like composite monofilament on the surface and a preparation method and application thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, hair products have become an important fashion accessory in modern life, and the annual consumption in the world is about 150,000 tons. With the continuous growth of the hair products industry, the proportion of natural hair raw materials is decreasing. Especially with the increasing demand for hair products at home and abroad, and the strengthening of animal protection awareness in countries all over the world, the cost of raw materials for natural hair is gradually increasing. As a substitute for natural hair products, imitation natural hair products or wig products have Great prospects for development. [0003] In the prior art, the chemical fibers used in imitation natura...
