Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a composite polyester dyed fabric with antibacterial and radiation-proof properties. Background Art

[0002] Polyester is a synthetic fiber made by spinning polyester, a polymer compound formed by the polycondensation of organic dibasic acids and diols. Invented in 1941, it is currently the leading synthetic fiber. The greatest advantages of polyester fiber are its excellent wrinkle resistance and shape retention, as well as its high strength and elastic recovery. It is also durable, wrinkle-resistant, iron-resistant, and non-sticky.

[0003] China Patent Authorization Publication Number: CN 218660768 U, Authorization Publication Date: March 21, 2023. This utility model discloses a light-shielding and radiation-resistant polyester fabric, comprising a polyester base fabric layer, a light-shielding layer bonded to one side of the polyester base fabric layer, a radiation-proof layer bonded to one side of the light-shielding layer, a protective layer bonded to a side of the radiation-proof layer away from the light-shielding layer, the protective layer comprising an antibacterial layer bonded to one side of the radiation-proof layer, a waterproof and breathable membrane bonded to one side of the antibacterial layer, and a wear-resistant layer bonded to one side of the waterproof and breathable membrane. This technical solution has the disadvantage that the fabric product has a single performance, and the base fabric layer is easily directly damaged when the inner side of the finished product (the side without light-shielding and radiation-resistant effects) is contacted by an object. In particular, the base fabric layer is easily corroded by direct bacterial growth and penetration, affecting the long-term comfort and health of use, resulting in reduced product quality and shortened service life.

[0004] In summary, polyester fabric has the disadvantages of poor overall antibacterial ability, low comfort in use, and reduced product quality and service life. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of polyester cloth in the prior art, such as poor overall antibacterial ability, low comfort in use, reduced product quality and shortened service life, and provides an antibacterial and radiation-proof composite polyester dyed cloth with improved overall antibacterial performance, improved product quality, comfort in use and extended service life.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A composite polyester dyed cloth with antibacterial and radiation-proof properties comprises a base fabric layer, which is interwoven with warp and weft threads; an outer side of the base fabric layer is connected to a first antibacterial layer; a side of the first antibacterial layer is connected to an anti-radiation layer; an inner side of the base fabric layer is connected to a second antibacterial layer; both the anti-radiation layer and the second antibacterial layer are connected to a waterproof and breathable membrane layer; and a side of the waterproof and breathable membrane layer is connected to a wear-resistant layer.

[0008] The outer surface of the base fabric layer is sequentially connected with an antibacterial layer 1, an anti-radiation layer, a waterproof and breathable membrane layer, and a wear-resistant layer. The inner surface of the base fabric layer is sequentially connected with an antibacterial layer 2, a waterproof and breathable membrane layer, and a wear-resistant layer. This ensures that the outer side of the base fabric layer has antibacterial properties against the environment, and the inner side has antibacterial properties against contact objects, achieving dual antibacterial properties in the finished product. The anti-radiation layer is placed on the outer side of the base fabric layer to protect the antibacterial layer and the base fabric, improving UV resistance, preventing aging and fading, and thereby enhancing the overall tear resistance of the fabric. The waterproof and breathable membrane layer prevents leakage and corrosion of internal substances, waterproofs the external environment from entering, and allows for ventilation between the internal and external environments. The wear-resistant layer improves the wear resistance of the inner and outer sides after contact, preventing pilling that causes surface wear and aesthetic damage, while also isolating and protecting the inner layer to extend its service life. This results in a composite polyester dyed fabric with antibacterial, sun-proof, anti-aging, tear-resistant properties, leakage and corrosion resistance, breathability, improved wear resistance, user comfort, and protection of the fabric's surface aesthetics, extending its service life.

[0009] Preferably, the warp and weft of the base fabric layer are blended wefts, and both are woven from bamboo charcoal fiber, acetate fiber, silk cotton fiber, and polyester yarn. In addition to polyester warp yarns spun from the polycondensation of organic dibasic acids and glycols, the blended weft and warp of the base fabric layer also incorporate bamboo charcoal fiber and acetate fiber, imparting natural antibacterial properties to the base fabric layer, further enhancing its antibacterial effect. The silk cotton fiber and polyester yarn are combined with bamboo charcoal fiber to enhance the strength and tensile strength of the base fabric layer, while the polyester yarn is blended with RPET yarn to ensure the environmental friendliness of the base fabric. This results in improved antibacterial properties and tensile strength of the dyed fabric, while also providing renewable, green production benefits.

[0010] Preferably, the first and second antibacterial layers are cross-woven from blended weft and warp yarns, each of which is a blend of bamboo charcoal fiber, acetate fiber, and chitosan fiber. The blended weft and warp yarns of bamboo charcoal fiber, acetate fiber, and chitosan fiber impart high antibacterial properties to the base fabric, ensuring the dyed fabric possesses high antibacterial efficacy.

[0011] Preferably, the radiation protection layer is made of a cross-woven blended weft and warp, both of which are woven from hemp and cotton fibers. The surface of the radiation protection layer is coated with titanium dioxide and zinc oxide. Hemp fibers have a smooth surface, are relatively straight, and are less prone to deformation. The hemp-blended cotton fiber serves as the contact surface layer, enhancing its strength and skin-friendliness. Furthermore, the titanium dioxide and zinc oxide coatings on the surface layer ensure the radiation protection layer's high UV resistance. This improves the fabric's strength, skin-friendliness, and sun protection.

[0012] Preferably, the waterproof and breathable membrane layer is a TPU waterproof and breathable membrane. TPU waterproof and breathable membrane is a polymer waterproof material with excellent elasticity, high strength, and strong waterproof properties. It can withstand water pressures exceeding 10,000 mm. This ensures the fabric's waterproof and load-bearing capacity, while increasing strength and extending its service life.

[0013] Preferably, the wear-resistant layer is made from a cross-woven blended weft and warp, both of which are woven from bamboo fiber and Tencel. Bamboo fiber is wear-resistant, pilling-free, highly absorbent, quick-drying, highly breathable, and has excellent natural antibacterial properties and is environmentally friendly. The blend of bamboo fiber and Tencel provides enhanced flexibility to compensate for the tensile strength of bamboo fiber. This achieves the green production benefits of ensuring and improving the wear resistance and breathability of the dyed fabric while enhancing antibacterial properties and protecting the environment.

[0014] The beneficial effects of the utility model are: the composite polyester dyed cloth has antibacterial, sun-proof, anti-aging and tearing properties; is comfortable to use; is leak-proof and anti-corrosion; is breathable, improves wear resistance and protects the surface aesthetics of the cloth; extends service life; has renewable green production benefits; and is skin-friendly.
