Description

Technical Field

[0001] The utility model relates to a clothing accessory, in particular to a fire-resistant and flame-retardant printed clothing piece. Background Art

[0002] When making clothes, it is usually necessary to cut the fabric into pieces, such as the front piece, back piece, sleeve piece, etc., and then sew the pieces together. For some special types of work clothes, in order to improve work safety, the pieces of clothing in specific parts are required to have fire retardant properties.

[0003] The traditional way to improve the fire retardant properties of garment pieces is mainly to compound a fire retardant layer on the outer surface of the garment pieces, which makes the garment pieces relatively thick, the weight of the clothes produced is relatively large, the air permeability is low, the wearing comfort is relatively poor, and the surface cannot be printed, and the appearance is relatively simple.

[0004] In view of this, the applicant conducted in-depth research on fire-retardant clothing panels, which led to the present case. Utility Model Content

[0005] The utility model aims to provide a fire-proof and flame-retardant garment piece which has relatively good wearing comfort and large appearance design space.

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

[0007] A fireproof and flame-retardant printed garment piece comprises a woven fabric, wherein the woven fabric comprises a high-elastic base layer and a low-elastic surface layer, a plurality of strip-shaped cavities are formed between the high-elastic base layer and the low-elastic surface layer, and the high-elastic base layer and the low-elastic surface layer are interwoven and connected with each other at positions where the strip-shaped cavities are not formed, the strip-shaped cavities are filled with flame-retardant particles, and a fireproof printed layer is arranged on the side of the low-elastic surface layer away from the high-elastic base layer.

[0008] As an improvement of the utility model, the strip-shaped cavity is also filled with aluminum hydroxide particles.

[0009] As an improvement of the present invention, the flame retardant particles are ceramic alumina particles.

[0010] As an improvement of the present invention, the low-elastic surface layer includes first warp yarns and first weft yarns interwoven with each other, and the first warp yarns and the first weft yarns are both aramid flame-retardant yarns.

[0011] As an improvement of the present invention, the high-elastic bottom layer includes a second warp yarn and a second weft yarn interwoven with each other, the second warp yarn is a modal acrylic yarn and the second weft yarn is a cotton-polyester blended yarn, or the second weft yarn is a modal acrylic yarn and the second warp yarn is a cotton-polyester blended yarn, the cotton-polyester blended yarn is formed by twisting cotton fibers and shaped polyester fibers, and the outer surface of the shaped polyester fibers has strip grooves.

[0012] As an improvement of the utility model, the cross section of the special-shaped polyester fiber is star-shaped, cross-shaped or multi-lobed.

[0013] By adopting the above scheme, the utility model has the following beneficial effects:

[0014] 1. By setting a fireproof printing layer, the printing layer is directly used to achieve fire prevention without the need for a composite fireproof and flame-retardant layer, which helps to reduce the thickness and weight of the garment, provides relatively good wearing comfort and greater space for appearance design.

[0015] 2. By filling flame-retardant particles, the high-elastic bottom layer is made to bulge inward, which not only helps to improve the flame-retardant properties, but also prevents the high-elastic bottom layer from being completely attached to the skin, thereby achieving better breathability and moisture conduction effects.

[0016] 3. By selecting specific yarns, it helps to further improve the fire retardant properties and / or breathable and moisture conduction capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 The utility model is a schematic diagram of the structure of the fire-retardant printed garment piece.

[0018] The markings in the figure correspond to the following:

[0019] 10-high elastic bottom layer; 11-strip cavity;

[0020] 12-convex strip; 20-low elastic surface layer;

[0021] 30- Fireproof printing layer. DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, this embodiment provides a fire-retardant printed garment piece, including a woven fabric, and the woven fabric includes a high-elastic base layer 10 and a low-elastic surface layer 20. It should be noted that the high elasticity and low elasticity are relative and do not refer to specific elasticity, as long as the elasticity of the base layer is higher than the elasticity of the surface layer.

[0024] A plurality of strip-shaped cavities are formed between the high-elastic bottom layer 10 and the low-elastic surface layer 20, and the high-elastic bottom layer 10 and the low-elastic surface layer 20 are interwoven and connected at positions where the strip-shaped cavities are not formed, that is, when knitting, the high-elastic bottom layer 10 and the low-elastic surface layer 20 are not connected at some positions, so that strip-shaped cavities 11 are formed at these positions. The strip-shaped cavities 11 are filled with flame-retardant particles. Since the elasticity of the bottom layer is higher than that of the surface layer, after the flame-retardant particles are filled, the high-elastic bottom layer 10 will produce elastic deformation, and then bulge inward to form convex strips 12 that contact human skin when used, which can prevent the high-elastic bottom layer 10 from being completely attached to the skin, and can achieve better air permeability and moisture conduction effects.

[0025] The flame retardant particles are preferably ceramic alumina particles, which have good high temperature resistance and heat insulation capabilities, and can slow down the temperature transfer from the low-elastic surface layer 20 to the high-elastic bottom layer 10, avoiding skin burns, and also preventing the high-elastic bottom layer 10 from being ignited at high temperatures. If necessary, the strip-shaped cavity can also be filled with aluminum hydroxide particles at the same time, which will be thermally decomposed at high temperatures and produce crystal water, which helps to extinguish open flames. At the same time, the aluminum hydroxide particles will also absorb heat during the thermal decomposition process, making the local temperature of the garment piece lower than its ignition point, preventing the combustion from continuing.

[0026] A fireproof printing layer 30 is provided on the side of the low-elastic surface layer 20 away from the high-elastic bottom layer 10. The ink used in the fireproof printing layer 30 is a fireproof ink, which can be purchased directly from the market. It is not the focus of this embodiment and will not be described in detail this time.

[0027] Preferably, the low-elastic surface layer 20 includes a first warp yarn and a first weft yarn interwoven with each other, wherein the first warp yarn and the first weft yarn are both aramid flame-retardant yarns, which helps to further improve the fire-retardant performance. The high-elastic bottom layer 10 includes a second warp yarn and a second weft yarn interwoven with each other, wherein the second warp yarn is modal acrylic yarn and the second weft yarn is cotton-polyester blended yarn, or the second weft yarn is modal acrylic yarn and the second warp yarn is cotton-polyester blended yarn, and whether the modal acrylic yarn is specifically the second warp yarn or the second weft yarn depends on the length direction of the strip cavity. When the second warp yarn is modal acrylic yarn, the strip cavity extends along the weft direction, and when the second weft yarn is modal acrylic yarn, the strip cavity extends along the warp direction. The cotton-polyester blended yarn is formed by twisting cotton fiber and shaped polyester fiber, wherein the outer surface of the shaped polyester fiber has strip grooves, and such shaped polyester fiber with strip grooves on the outer surface can be directly purchased from the market, for example, shaped polyester fiber with a star-shaped, cross-shaped or multi-leaf cross section. In this way, the elasticity of the high-elastic bottom layer 10 can be ensured by utilizing the elasticity of the modal acrylic yarn, the hygroscopicity of the cotton fiber can be utilized to improve the hygroscopic effect, and the strip grooves on the surface of the shaped polyester fiber can be utilized to increase the pores inside the high-elastic inner side 10, which can not only improve the air permeability, but also facilitate moisture discharge.

[0028] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various equivalent substitutions for the present invention based on the prior art, which all belong to the protection scope of the present invention.
