[0025] The present utility model provides a yarn for knitting a housing, and the yarn for knitting the housing is applied to the housing 3 of an intelligent terminal, specifically to the housing of a mobile phone.

[0026] In the embodiment of the present utility model, please refer to the figure. The cross-section of the yarn is a two-layer structure, including a base material layer 2 and a coated luminous layer 1 which are stacked. Further, the sum of the thicknesses of the base material layer 2 and the coated luminous layer 1 is greater than or equal to 0.1 mm and less than or equal to 0.16 mm. When the thickness of the yarn is greater than or equal to 0.16 mm, the light transmittance becomes poor, which will reduce the luminous efficiency. When the thickness of the yarn is less than or equal to 0.1 mm, the overall yarn is too soft, which will affect the mechanical strength and aesthetic properties such as luminous brightness during knitting use. When the thickness of the yarn is greater than or equal to 0.1 mm and less than or equal to 0.16 mm, not only the durability is improved. And according to the research of the inventor, this thickness can balance the softness required for knitting and the protection required for the shell, so that the luminous yarn can be used to knit a mobile phone case. Using the yarn to knit the luminous part of the mobile phone case can improve the wear resistance of the luminous part of the mobile phone case compared with the method of directly sticking luminous stickers on the mobile phone case, and the use feel and aesthetic sense are better.

[0027] Further, the yarn diameter specification of the yarn is less than or equal to 1500 D, or greater than or equal to 600 D. This range can ensure that the shell has enough thickness to withstand external pressure and internal stress to ensure the structural stability; taking into account the aesthetic properties of the mobile phone case shell.

[0028] Further, the thickness of the base material layer 2 is greater than or equal to 0.01 mm and less than or equal to 0.05 mm. The thickness of the base material layer 2 within this range can ensure the bonding strength with the coated luminous layer and ensure a certain tensile strength during the subsequent knitting process. The thickness of the coated luminous layer 1 is greater than or equal to 0.05 mm and less than or equal to 0.15 mm. The thickness of the coated luminous layer 1 within this range can provide stable luminous performance.

[0029] Further, when the thickness of the base material layer 2 is less than the thickness of the coated luminous layer 1, in addition to reducing the product quality, the thicker functional layer can provide better protection to extend the service life. On the contrary, when the thickness of the base material layer 2 is greater than the thickness of the coated luminous layer 1, it will cause damage to the product quality, aesthetic properties, and weakening of functionality.

[0030] Further, by mass percentage, the carrier resin in the coated luminous layer 1 accounts for 30%-70%, the luminous inorganic substance accounts for 20%-70%, and the plasticizer and additives account for 0-10%.

[0031] Among them, the carrier resin for coating the light-emitting layer 1 can improve the thermal stability and chemical stability of the coated light-emitting layer 1. In addition, it can give a beautiful gloss and texture. The ratio is designed to ensure that the carrier resin can provide the necessary adhesion and stability to ensure the firm bonding between the coated light-emitting layer 1 and the substrate layer 2. And the mass fraction of the carrier resin should not exceed 70%, otherwise it will be difficult to ensure the softness and comfort of the mobile phone case shell. This mass fraction ratio can improve the stability during the processing and the durability during use.

[0032] Also, the luminescent inorganic substance has good luminous efficiency, emits light of a specific wavelength, excellent chemical stability and thermal stability, and it usually has a long service life and a low attenuation rate. Therefore, it can maintain stable luminous performance for a long time. Also, because the luminescent inorganic substance is easy to manufacture, not easy to burn, does not contain harmful substances, and different luminescent inorganic substances can achieve luminescence of multiple colors, providing consumers with a variety of choices. Therefore, the coated light-emitting layer 1 selects the luminescent inorganic substance as the luminescent material, and the mass fraction of the luminescent material should not be less than 20%, otherwise the required luminous efficiency and brightness cannot be obtained, and the highest mass fraction is 70%, so that the cost can be controlled while the luminous performance is ensured.

[0033] Finally, the plasticizer and the auxiliary agent, as auxiliary materials for the coated light-emitting layer 1, improve the luminous performance, durability and compatibility of the coated light-emitting layer 1. However, due to the high cost of the plasticizer and the auxiliary agent, and unnecessary problems may occur during recycling, the mass fraction content is not recommended to exceed 10%.

[0034] Furthermore, the coated light-emitting layer 1 is made of thermosetting resin and / or thermoplastic plastic, and rare earth luminescent materials, and the substrate layer 2 is made of plastic.

[0035] Among them,

[0036] The carrier resin components of the coated light-emitting layer 1 can be unsaturated polyester, acrylic resin, epoxy resin, phenolic resin, PET (polyethylene terephthalate), PVC (polyvinyl chloride), PP (polypropylene), PE (polyethylene), EVA (ethylene-vinyl acetate copolymer), PS (polystyrene), PMMA (polymethyl methacrylate), ABS (acrylonitrile-butadiene-styrene terpolymer), Silicone (silicone rubber), PU (polyurethane), TPU (thermoplastic polyurethane elastomer), PA (polyamide), PA6 (polyamide 6), PA66 (nylon 66), PC (polycarbonate), etc.

[0037] The luminescent substance includes one or more mixtures of rare earth silicate, aluminate, sulfide, etc.

[0038] The plasticizer can be dibutyl sebacate, di-n-butyl phthalate, dioctyl sebacate, dioctyl adipate, di-n-octyl phthalate, diisooctyl phthalate, tricresyl phosphate, phenyl alkyl sulfonate, cyclohexanone, etc.

[0039] The auxiliaries include stabilizers, softeners, toughening agents, cold-resistant agents, lubricants, extenders, etc.

[0040] The substrate layer 2 is made of plastic, and usually can be transparent or non-transparent materials such as PE (polyethylene), PU (polyurethane), PA (polyamide), PET (polyethylene terephthalate), PC (polycarbonate), PVC (polyvinyl chloride), COP (cycloolefin polymer), TAC (triacetate cellulose), PMMA (polymethyl methacrylate), OPP (oriented polypropylene), etc.

[0041] Furthermore, the luminescent inorganic substance is directly inside the carrier resin and evenly distributed to ensure uniform luminescence on the entire surface or volume of the material, maintain a consistent luminescence effect, improve the overall luminescence efficiency, and improve cost-effectiveness.

[0042] Furthermore, the coated luminescent layer 1 and the substrate layer 2 are joined together by hot pressing so that the coated luminescent layer and the substrate layer can penetrate each other. The hot pressing process can melt or soften the adhesive or resin between the two at high temperature, thereby enhancing the adhesion between the two; improving the interfacial properties between the two; and precisely controlling the thickness of the composite material to meet the usage requirements of the mobile phone case housing.

[0043] In one embodiment, at least part of the intelligent terminal housing 3 is woven with yarns for weaving the housing. The woven yarns can not only provide good structural strength, but are also very important for reducing the mass. Its aesthetics and customization can meet the needs of different customers.

[0044] In one embodiment, the intelligent terminal housing 3 is made of a glow-in-the-dark synthetic fiber mixed woven fabric, and the glow-in-the-dark synthetic fiber mixed woven fabric is woven and mixed by the yarns for weaving the housing and synthetic fibers in a plain weave and / or twill weave, etc.

[0045] Among them, the reason why the intelligent terminal housing 3 uses the glow-in-the-dark synthetic fiber mixed woven fabric is not only because of its aesthetics and durability, but also because of its light weight and good stability; the glow-in-the-dark synthetic fiber mixed woven fabric is woven and mixed by the yarns for weaving the housing and synthetic fibers in one or more ways such as plain weave and / or twill weave. This design makes there be no gaps between the woven yarns, which can create different texture effects and increase aesthetics. This mixed weaving technology can enhance the mechanical properties such as tensile resistance and tear resistance of the fabric and improve the overall durability of the fabric.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
