Description
Technical Field
The invention relates to the field of recycling of waste textiles, in particular to a method for producing rhombic fancy yarns by using waste textiles.
Background
Textiles are indispensable articles in human life. With the increase of population and the improvement of the living quality of people, the number of the consumed textiles of people increases year by year, and the treatment of a large amount of waste textiles becomes a difficult problem. The waste textile incineration treatment causes air pollution, and the landfill treatment affects the ecological environment of soil; the method for treating the textile by a chemical method and then re-spinning or processing the textile into other industrial raw materials is a method for recycling more thoroughly, but the recycling cost is higher. The method has the characteristics of low cost, simple process and the like, but mostly has the defect of low added value of products. Therefore, the research and development of a waste textile recycling method based on a mechanical method and having a high added value of the product is undoubtedly required in the field of waste textile recycling.
The fiber can be obtained from the waste textile by adopting a mechanical method, but due to the aging and mechanical damage of the fiber, the strength and the length of the fiber can be lost in different degrees, so that the spinnability of the fiber is reduced, and the service performance and the added value of the product are reduced. In the literature, "once tauao. regenerated silk and wool blended yarn and fabric process research and product development [ D ]. zhejiang university of physics, 2018 ] waste textiles are opened into fiber raw materials by a mechanical opening method, regenerated protein wool fibers which can be used for spinning are used for spinning, regenerated silk/wool blended yarns obtained by ring spinning are reused for preparing regenerated garment materials, and fiber raw materials which cannot be used for spinning are used for preparing high-grade carpet raw materials.
The structure of the diamond-shaped fancy yarn is that parallel filament yarns or short fiber yarns with large linear density and no twist or weak twist (fluffy) are taken as core yarns, so that after wrapping outer wrapping yarns, a compression effect is formed, and then two kinds of filament yarns or short fiber yarns with different colors are respectively wrapped in different twisting directions, so that the appearance presents a diamond-shaped effect.

The method overcomes the technical bias of the application of the recycled fiber at present, the recycled fiber is firstly applied to the preparation of the diamond-shaped fancy yarn through proper process steps and parameter adjustment, not only the recycling of waste textiles is realized, the cost is low, but also the added value of the product is improved, and the diamond-shaped fancy yarn obtained by taking the low-grade recycled fiber as the raw material can be widely applied to high-grade products such as high-grade clothes, decorative textiles and the like.
(2) According to the method, the recycled fibers are blended with other fibers by an improved blending process to obtain the roving with reasonable linear density, so that the defects of the recycled fibers in strength and length are overcome, and the spinnability of the recycled fibers is improved; and then the roving is directly used as the core yarn, and the finished product is obtained after the roving is wrapped by sparse functional filaments, so that the problems of uneven yarn evenness, more broken ends and the like caused by short length and low strength of the recycled fiber when the roving mixed with the recycled fiber is adopted to spin the spun yarn are ingeniously avoided. The finished product can realize the effect of the rhombic fancy yarn, not only has the advantages of high yarn strength, less hairiness and wide raw material source, but also presents special rhombic color appearance, can be directly used for knitting or weaving, and meets different requirements of consumers.
(3) The performances of the raw materials are organically combined with the structure and the appearance of the yarn, the filaments with different functions and colors can be wrapped outside the roving obtained by blending the raw materials with different colors, so that various required functions of the rhombic fancy yarn can be simultaneously presented with the rhombic appearance structure, the unique color matching and the rich and colorful style, the subsequent dyeing is not needed, and the application field is expanded.
(4) The raw material selection adopts the waste fabrics, practices the environmental protection concept of waste textile recycling and practices the environmental protection concept of green development and cyclic utilization, and has wider market value and application prospect.
(5) The diamond fancy yarn can be widely applied to developing clothing products such as knitted coats, gloves, scarves and the like, can also be used for manufacturing household textiles such as cushions, carpets, sofa covers and the like, and has a wide application range.
