Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester filament technology, specifically to a flame-retardant and UV-resistant polyester fiber filament. Background Technology
[0002] Polyester fiber, commonly known as "polyester," is a synthetic fiber made from organic diacids and diols through chemical polycondensation. It belongs to the category of polymer compounds and is widely used in textile and clothing manufacturing.
[0003] For example, patent publication number CN 214088805 U describes a flame-retardant and UV-resistant polyester fiber filament. By combining cotton and linen fiber filaments as the main body, the heat dissipation and breathability of curtains made from polyester filament are improved. Furthermore, by combining spandex elastic fiber filaments with the polyester filament main body, the curtains made from polyester filament have good elasticity and drape, enhancing their aesthetic appeal. By combining the polyester filament main body with a cotton-nylon flame-retardant fabric layer, the flame-retardant effect of the curtains made from polyester filament is improved, enhancing their safety during use. Finally, the UV-resistant fabric layer enhances the UV resistance of the curtains made from polyester filament, thereby improving their practicality.
[0004] However, the poor connection between the individual fibers and the main body of the polyester filament results in unstable performance of the main body, which urgently needs improvement. Utility Model Content
[0005] The purpose of this invention is to provide a flame-retardant and UV-resistant polyester fiber filament to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant and UV-resistant polyester fiber filament, comprising a polyester filament body, a plurality of fixed grooves arranged in a ring array on the outer circumference of the polyester filament body, elastic polyester filament, linen polyester filament and cotton polyester filament arranged and wound in the plurality of fixed grooves, the same flame-retardant layer being sleeved on the outer circumference of the elastic polyester filament, linen polyester filament and cotton polyester filament, and a UV-resistant layer being fixedly sleeved on the outer circumference of the flame-retardant layer, and a telescopic cavity being provided between the inner circumference of the flame-retardant layer and the outer circumference of the polyester filament body.
[0007] In the preferred embodiment, the outer circumferential wall of the flame-retardant layer is provided with a number of reinforcing grooves arranged in a ring array, and the inner circumferential wall of the UV-resistant layer is provided with fixing ears that are adapted to the reinforcing grooves.
[0008] Furthermore, the radii of elastic polyester filament, linen polyester filament, and cotton polyester filament are consistent and fall between 10% and 15% of the main radius of polyester filament.
[0009] Furthermore, the inner cavity spacing of the telescopic cavity is less than 3% of the radius of the polyester filament body.
[0010] Furthermore, the depth of the reinforcement groove is less than half the thickness of the flame-retardant layer.
[0011] Furthermore, more than 30% peach skin velvet spring satin has been added to the UV-resistant layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] A flame-retardant and UV-resistant polyester fiber yarn, through the opening of the fixing groove, facilitates better bonding of elastic polyester yarn, linen polyester yarn and cotton polyester yarn with the polyester yarn body, and the flame-retardant layer provides fire resistance and heat resistance to the polyester yarn body. The setting of the expansion cavity can reduce the deformation rate of the polyester yarn body, and the setting of the UV-resistant layer can provide excellent UV protection for the human body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In daily life, different functional fabrics are needed. This case provides a flame-retardant and UV-resistant polyester fiber yarn, which can be used for sunshade curtains and sun protection fabrics.
[0020] like Figures 1-3As shown, this utility model provides a technical solution: a flame-retardant and UV-resistant polyester fiber filament, comprising a polyester filament body 1. Several annularly arranged fixing grooves are formed on the outer circumference of the polyester filament body 1. Elastic polyester filament 2, linen polyester filament 3, and cotton polyester filament 4 are wound and arranged in the fixing grooves. A common flame-retardant layer 5 is sleeved on the outer circumference of the elastic polyester filament 2, linen polyester filament 3, and cotton polyester filament 4. A UV-resistant layer 6 is fixedly sleeved on the outer circumference of the flame-retardant layer 5. A telescopic cavity 7 is provided between the inner circumference of the flame-retardant layer 5 and the outer circumference of the polyester filament body 1. The fixing grooves facilitate better adhesion between the elastic polyester filament 2, linen polyester filament 3, and cotton polyester filament 4 and the polyester filament body 1. The flame-retardant layer 5 provides fire resistance and heat resistance to the polyester filament body 1. The telescopic cavity 7 reduces the deformation rate of the polyester filament body 1. The UV-resistant layer 6 provides excellent UV protection for the human body.
[0021] like Figures 2-3 As shown, the outer circumferential wall of the flame-retardant layer 5 has several reinforcing grooves 8 arranged in a ring array, and the inner circumferential wall of the UV-resistant layer 6 has fixing ears that are adapted to the reinforcing grooves 8. The reinforcing grooves 8 and the fixing ears limit each other, which improves the stability of the connection between the flame-retardant layer 5 and the UV-resistant layer 6.
[0022] The elastic polyester filament 2, linen polyester filament 3, and cotton polyester filament 4 have the same radius and are between 10% and 15% of the radius of the polyester filament body 1. The limited radius of the elastic polyester filament 2, linen polyester filament 3, and cotton polyester filament 4 can ensure the sturdiness of the polyester filament body 1, avoid the polyester filament body 1 from breaking due to the fixing groove opened on the polyester filament body (1) being too deep, and improve the stability of the polyester filament.
[0023] like Figure 3 As shown, the inner cavity spacing of the telescopic cavity 7 is less than 3% of the radius of the polyester filament body 1. The limited inner cavity spacing of the telescopic cavity 7 can ensure that the polyester filament body 1 can be fixed within the telescopic cavity 7 while also increasing the deformation space of the polyester filament body 1, thereby improving the stability of the polyester filament.
[0024] The depth of the reinforcing groove 8 is less than half the thickness of the flame-retardant layer 5. The limited depth of the reinforcing groove 8 also ensures the stability of the flame-retardant layer 5 itself, preventing cracking of the flame-retardant layer 5.
[0025] The UV protection layer 6 contains over 30% peach skin velvet spring satin. Peach skin velvet spring satin offers excellent UV protection and does not produce any odor during UV protection. The addition of peach skin velvet spring satin to the UV protection layer 6 makes it more suitable for everyday use.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
