Decorative fabrics are generally used in wall coverings, curtains, bedding, sofa fabrics, etc. In the process of using decorative fabrics, there are high requirements for the selection and matching of fabric texture, color uniformity, overall configuration, etc., especially in coloring. Color fastness, referred to as color fastness, refers to the degree of fading of dyed fabrics under the influence of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) during use or processing. It is an important indicator of fabrics. At present, the fabrics on the market have obvious fading problems after long-term use, which affects the aesthetic performance and service life of the fabrics.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Embodiment 1

[0032] like Figure 1 As shown, a high color fastness decorative fabric comprises a base fabric layer and a decorative layer; the decorative layer is fixed to the outer surface of the base fabric layer by an adhesive layer; the adhesive layer comprises adhesive points arranged in an array; the decorative layer is woven into a mesh by warp yarns and weft yarns, the warp yarns are polyester fiber yarns, the weft yarns are bamboo charcoal fiber yarns, and the outer surface of the decorative layer is formed by raising the weft yarns to form a suede layer; the outer surface of the decorative layer is also provided with a waterproof membrane layer; the base fabric layer is a high color fastness base fabric layer.

[0033] Specifically, the adhesive layer includes adhesive points arranged in an array, which are evenly coated in a single-layer adhesive point array arrangement, and the adhesive is firmly bonded. Furthermore, the decorative layer is woven into a mesh by warp yarn and weft yarn, which has good air permeability. In addition, the fiber characteristics of polyester fiber yarn and bamboo charcoal fiber yarn make the fabric have moisture absorption and breathability. Furthermore, the outer surface of the decorative layer is formed into a velvet layer by raising the weft yarn, so that the outer surface has a large contact area with the air, which not only has a decorative effect, but also makes the color of the dyed fabric product more uniform. In addition, the decorative layer uses the characteristics of the yarn to absorb moisture that penetrates into the fabric, prevent the interior from getting damp and moldy, and thus improve the color fastness of the fabric.

[0034] Furthermore, the waterproof membrane layer is made of PTFE membrane for clothing, which can improve the waterproofness of the fabric and prevent damage to the dyeing structure; secondly, the high mechanical strength of the membrane material is used to prevent the fabric from fading when washed or rubbed. These two aspects ensure the high color fastness of the fabric as a whole. Furthermore, the base fabric layer is a high color fastness base fabric layer, which is woven from high color fastness polyester fibers.

[0035] Embodiment 2

[0036] like Figure 2-4 , which is different from the above-mentioned embodiment 1, the high color fastness base fabric layer is knitted with high color fastness fiber yarn using a two-needle upper needle disc and a two-needle lower needle cylinder, and using a six-way one-cycle:

[0037] 1st loop forming system: two needles on the upper needle disc form loops, and two needles on the lower needle cylinder form floating threads;

[0038] Second loop forming system: one tuck and one floating needle on the upper needle disc, one floating needle and one tuck on the lower needle cylinder;

[0039] 3rd loop forming system: two needles on the upper needle disc form loops, two needles on the lower needle cylinder form floating threads;

[0040] 4th loop forming system: two needles on the upper needle disc float the thread, and two needles on the lower needle cylinder form the loop;

[0041] 5th loop forming system: one floating needle and one tuck needle on the upper needle disc, one tuck needle and one floating needle on the lower needle cylinder;

[0042] The 6th loop system: two needle floats on the upper needle disc and two needle loops on the lower needle cylinder. The fabric weaving structure is used to weave the base fabric layer with high color fastness. The 1st and 6th loops ensure the stability of the peripheral structure of the fabric; the 2nd and 5th loops, within the same weaving range, expand the gaps in the fabric layer as much as possible to enhance the breathability of the fabric; the 3rd and 4th loops echo the 1st and 6th loops, making the 2nd and 5th loops high in space, and the fabric has a layered beauty.

[0043] Furthermore, the high color fastness fiber yarn is formed by twisting a fixed number of degradable high color fastness fibers in the Z direction. Still further, the degradable high color fastness fiber comprises a copolymer core layer and a low melting point polyester sheath layer. Specifically, the copolymer core layer of the degradable high color fastness fiber is a copolymer of PBS and a low melting point polyester, and the low melting point polyester is a low melting point polyester containing a benzene ring structure, so that the two component materials in the degradable high color fastness fiber can be fully integrated and give play to their respective advantages, not only having the advantages of biodegradability and high color fastness, but also having the characteristics of fiber softness and high service life.

[0044] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
