Detailed Description

The following detailed description and specific examples are given for illustrative purposes only, and are not intended to limit the scope of the present disclosure; however, it should be understood by those skilled in the art that the present invention is not limited to these examples, and other equivalent functions and steps may be performed to achieve the present invention.

Furthermore, it will be apparent to those skilled in the art that: the illustrated embodiments and drawings are only for reference and illustrative purposes and are not intended to limit the invention; modifications and variations that can be easily made based on the above descriptions are also regarded as being within the scope not departing from the spirit and the purpose of the present invention, and all of the inventions are also included in the claims of the present invention.

First, please refer to fig. 1A and 1B, which are enlarged schematic views of a first embodiment of the fancy yarn of the invention. In the present embodiment, the fancy yarn for environmental protection includes at least two core wires 11 constituting a warp 10 and at least one finishing wire 20 which is woven, interwoven or entangled with the warp 10 to constitute a weft; as shown in fig. 1A, the cover thread 20 is a split type yarn chain having openings, and the openings 21 are wound along the warp yarn 10 to form a spiral structure, wherein the pitch of the threads in the spiral structure is not particularly limited, and may be an equal pitch thread or an unequal pitch thread. In addition, in other embodiments of the present invention, the fancy yarn may further include two decoration lines 20, and the two decoration lines are opposite to each other along the winding direction of the warp 10.

As shown in fig. 1B, the decoration thread 20 may also be a closed loop type yarn chain having closed loops, the closed loops 22 are knot structures formed by winding along the warp yarns 10, and the size and the pitch of the closed loops are not particularly limited and may be determined according to actual requirements.

According to the technical idea of the present invention, the core wire 11 is formed of one first monofilament or one first yarn bundle including a first straight yarn bundle in which a plurality of first monofilaments are arranged in parallel or a first twisted yarn bundle in which a plurality of first monofilaments are twisted.

The finishing thread 20 is formed by one second monofilament or one second yarn bundle including a second straight yarn bundle in which a plurality of monofilaments are arranged in parallel or a second twisted yarn bundle in which a plurality of monofilaments are twisted.

According to the technical idea of the invention, the first monofilament and/or the second monofilament are made of environment-friendly materials, so that the environmental problem caused by waste treatment after use can be avoided, and the first monofilament and/or the second monofilament can be recycled or return to nature; the environment-friendly material can be natural materials such as cotton, bamboo fiber, rayon, chitin fiber, wool, silk, polylactic acid fiber, coconut carbon fiber and the like, recyclable high polymer materials such as Polyester (Recycled Polyester), Nylon (Recycled Nylon) and the like, or materials with Global recycling standard (Global Recycled System) certification.

For example, polyester widely used for producing pet bottles has the property of being undecomposed, is easy to cause harm to the environment, and gradually attracts attention as an important raw material for regenerating environment-friendly textiles under the trends of increasingly exhausted petroleum yield and high oil price, so that a pet bottle recycling system is established in many countries in the early years to solve the irresistible environmental pressure. The polyester fiber recycled and reproduced from the PET bottle is used as the raw material, so that the damage of a large amount of polyester bottle wastes to the environment can be reduced, the petroleum consumption can also be reduced, and the energy is saved by about 80 percent compared with the original polyester fiber by using the polyester fiber recycled and reproduced from the PET bottle as the raw material, namely, the emission of 75 percent of carbon dioxide is reduced.

The polylactic acid fiber is obtained by polycondensation of lactic acid obtained from starch such as corn, which is a natural material, as a polymer material. When the polylactic acid fiber is discarded after use, the polylactic acid fiber can be decomposed into water and carbon dioxide through microorganisms in soil, the generated carbon dioxide can be absorbed through photosynthesis of plants, the pollution to the earth environment is avoided, and the polylactic acid fiber is a completely natural circulation type biodegradable fiber.

In addition, natural material products have also been drawing attention in recent years, and for example, spider silk proteins are produced as spider silks by transferring spider genes to plant cells or goats, or colored cotton is produced by modifying cotton genes by using genetic gene technology and gene modification technology; moreover, the coconut charcoal fiber is regenerated and utilized by using waste coconut shells, and the generation of waste can be effectively reduced. Thus, the above materials can be used for the fiber materials of the first and second monofilaments of the present invention, and the fiber materials used for the first and second monofilaments can be the same or different.
