BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1The utility model relates to a structure diagram of the anti-fouling wrinkle resistant polyester composite fabric.

[0010] In the figure: 1 - anti-fouling layer, 2 - polyester fabric layer, 3 - point hot melt PU glue, 4 - anti-fouling yarn, 5 - anti-static yarn. DETAILED DESCRIPTION

[0011] The utility model is further explained below in combination with the drawings and specific embodiments.

[0012] Embodiment one

[0013] In combination Figure 1 The embodiment is explained in detail, an anti-fouling wrinkle resistant polyester composite fabric, including: anti-fouling layer 1 and polyester fabric layer 2;The anti-fouling layer 1 and polyester fabric layer 2 are made into compound by point hot melt PU glue 3;The anti-fouling layer 1 is interwoven by warp and weft;The warp and weft include anti-fouling yarn 3;The anti-fouling yarn 4 is with spandex fiber filament as the core, and the outside is wrapped PTT fiber;The polyester fabric layer 2 is interwoven by wrinkle resistant yarn;The wrinkle resistant yarn includes core yarn and wrapping yarn, the wrapping yarn is spirally wrapped outside the core yarn, the core yarn is elastic filament, and the wrapping yarn is polyester fiber filament.

[0014] PTT fiber has the excellent properties of polyester fiber and nylon, such as the resilience characteristics and inherent stain resistance of nylon, and also has excellent comfort, softness and easy dyeability. The stain resistance is related to the oil repellency and easy stain removal of the fiber, and the chemical structure of the PTT fiber macromolecular chain greatly influences the surface tension. The critical surface tension of the PTT fiber with an odd number of methylene groups is lower than that of an even number, and the PTT fiber has good stain resistance.

[0015] The point hot melt PU glue 3 is arranged in an array between the anti-fouling layer 1 and the polyester fabric layer 2 when compounding the two layers, and the two layers are connected at the position of the point hot melt PU glue 3. The adjacent point hot melt PU glues 3 have gaps therebetween, which can ensure the elastic recovery performance of the anti-fouling layer 1 and the polyester fabric layer 2.

[0016] Further, the elastic filament is a T400 filament. Specifically, the specification of the T400 filament is 3.33tex / 24F. T400 is a double-component composite elastic fiber made of PTT and PET through a composite spinning process, and has natural permanent spiral crimping, excellent loftiness and a particularly soft hand feeling. The mechanism of elasticity of T400 is self-crimping elasticity due to the difference in thermal shrinkage rate of PET and PTT, and the elastic stability and durability are good, so the elastic recovery performance of T400 is good.

[0017] During use or washing, the fabric is repeatedly rubbed to produce plastic bending deformation, thus forming wrinkles, and the wrinkles of the fabric directly affect the appearance flatness of the garment, and the ability of the fabric to resist such bending deformation is referred to as wrinkle resistance. The elasticity of the yarn affects the wrinkle resistance of the fabric, and the better the elastic recovery of the yarn, the better the wrinkle resistance of the fabric. The stain-resistant yarn 4 uses spandex filament as the core yarn, and the wrinkle-resistant yarn uses T400 filament as the core yarn, both of which have excellent elastic recovery, so that the fabric has good wrinkle resistance.

[0018] Further, the cross section of the polyester fiber filament is cross-shaped or Y-shaped. Specifically, in the embodiment, the cross section of the polyester fiber filament is cross-shaped, and the fiber has four grooves along the longitudinal direction, so that the moisture-conducting structure achieves the effect of moisture-conducting and quick-drying.

[0019] Embodiment two

[0020] The difference from embodiment one is that the outer part of the stain-resistant yarn 4 is attached with a three-proofing finishing agent. Specifically, the three-proofing finishing agent is UNIDYNE TG-5574 three-proofing finishing agent, and the stain-resistant yarn 4 attached with the three-proofing finishing agent can improve the stain resistance to common liquid stains such as milk, cola, coffee, and soy sauce to level 5.

[0021] The above describes the preferred embodiment of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the present application shall be within the protection scope defined by the claims.
