BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic structural diagram of the pleat-free polyester fabric involved in the utility model;

[0011] In the figure: 1-surface layer, 2-inner layer. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Embodiment 1

[0014] Combination Figure 1 The present embodiment is described in detail. A pleat-free polyester fabric comprises: a composite surface layer 1 and an inner layer, wherein the surface layer 1 is formed by interweaving a first warp yarn and a first weft yarn; the first warp yarn has an SPH filament as a core and is wrapped with cotton fiber on the outside; an anti-wrinkle finishing agent is attached to the outside of the first warp yarn; the first weft yarn has an SPH filament as a core and is spirally wound with antistatic polyester fiber filaments on the outside; the inner layer is formed by interweaving a second warp yarn and a second weft yarn; the second warp yarn is a moisture-conducting stretch yarn; and the second weft yarn is an antibacterial stretch yarn.

[0015] SPH filament is a kind of elastic fiber filament, which is made by parallel composite spinning of two polyester compounds with different thermodynamic properties, PTT and PET, and then processed by relaxation heat treatment to form curly fibers with fine and dense three-dimensional structure similar to wool. Its tensile resilience is close to that of spandex, while its elastic durability is better than that of spandex. Grooves are formed at the junction of the two components of the fiber. This special structure on the fiber surface gives the fabric moisture conduction, quick drying, moisture absorption and perspiration removal effects.

[0016] The first warp yarn with the anti-wrinkle finishing agent attached is flexible and wrinkle-resistant, improves the wrinkle recovery ability of the fabric, and has a good water-washing resistance effect. The anti-wrinkle finishing agent can avoid the shrinkage of cotton fibers after washing, has a good anti-shrinkage effect, makes the fabric wrinkle-resistant and iron-free, and maintains the original appearance characteristics.

[0017] The antistatic polyester fiber filament is a graphene-modified antistatic polyester fiber filament. Graphene with a mass fraction of 2.0% is added to the melted PET slices, stirred evenly, cooled and discharged, to obtain graphene-doped antistatic PET slices, which are then prepared by melt spinning. Graphene has good conductivity, and a lower content of graphene can well improve the conductive properties of polyester fibers. Adding 2.0% of graphene can reduce the mass specific resistivity of polyester by about 5 orders of magnitude, has good antistatic properties, and reduces the discomfort caused to the human body by static electricity during the wearing of the fabric.

[0018] Furthermore, the moisture-conducting elastic yarn has T400 filament as the core, and is spirally wound with cross-section polyester fiber filament on the outside. The cross-section polyester fiber filament has four grooves in the longitudinal direction. This moisture-conducting structure combines with the capillary effect, has good moisture-conducting and perspiration-wicking functions, and has fewer contact points with the skin, which can keep the skin dry and comfortable.

[0019] Furthermore, the antibacterial stretch yarn is made of T400 filament as the core and mint fiber is wrapped on the outside. Mint fiber is made of natural plants as raw materials, combined with nano-crushing technology and microcapsule technology, and the effective ingredients of mint are blended with cellulose in the form of microcapsule coating and spun into fibers, which not only ensures the good skin-friendliness and spinnability of the fiber, but also highlights its natural, green and healthy characteristics. Mint fiber has natural antibacterial function, and has good antibacterial properties against Staphylococcus aureus, Escherichia coli, and Candida albicans, with an antibacterial rate of 99%; mint fiber has the fragrance of mint, which can calm nervous emotions, boost spirits, and make the body and mind happy; mint fiber has passed the SGS coolness test and has a natural coolness.

[0020] T400 filament is a composite elastic fiber filament with high tensile strength and elasticity that is 2-5 times that of ordinary polyester filament. It has good elastic recovery and can maintain an elastic recovery rate of more than 95% even after 250 repeated stretchings. The cross-section of T400 filament is dumbbell-shaped, which is not only more fluffy and soft than ordinary polyester, but also has good moisture absorption and perspiration functions. The fabric woven with its core-spun yarn has a smooth surface and good wrinkle resistance.

[0021] Specifically, in this embodiment, the first warp yarn, the first weft yarn, the second warp yarn, and the second weft yarn have the same fineness, which is 100D. By weaving a fabric with yarns of the same fineness, wrinkles on the fabric caused by different yarn fineness can be avoided.

[0022] Fiber elasticity is the main factor affecting the wrinkle recovery of fabric. The addition of core yarn increases the proportion of fabric rapid elastic deformation. The core-spun yarn fabric with SPH filament and T400 filament as core yarn has the characteristic of rapid recovery in a very short time after wrinkling, making the fabric surface wrinkle-free and maintaining the original appearance characteristics, with good wrinkle resistance and ironing-free properties.

[0023] Furthermore, the surface layer 1 and the inner layer 2 are compounded by dot-shaped hot melt adhesive.

[0024] Embodiment 2

[0025] The difference from Example 1 is that the antibacterial elastic yarn uses T400 filament as the core and is wrapped with antibacterial seaweed fiber from Folium Isatidis. The antibacterial seaweed fiber from Folium Isatidis uses sodium alginate as the spinning raw material, adds Folium Isatidis extract to the sodium alginate spinning stock solution, is fully dispersed, and after standing and defoaming, uses calcium chloride as a coagulation bath, and is prepared by wet spinning technology. It can inhibit the growth of Escherichia coli and Staphylococcus aureus and has good antibacterial properties.

[0026] 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.
