NOVELTY - Anti-bacterial heating velvet blanket comprises a surface structure and a bottom structure. The raw material of the surface structure is 50-300 D/0.39-2.7dtex drawn textured yarn (DTY) low-elastic yarn containing graphene. The raw material of the bottom structure is polyester filament with a specification of 50-150D containing 35-20 wt.%. The mass percentage of the raw material of the dough structure in the fabric is 65-80 wt.%. The mass percentage of the raw material of the dough structure in the fabric is 65-80 wt.%. The graphene DTY low-elasticity yarn is obtained by adding 0.1-16 wt.% white graphene masterbatch to polyester chips by melt spinning. The graphene DTY low-elasticity yarn is obtained by adding 0.1-16 wt.% gray-black graphene masterbatch to polyester chips by melt spinning. The graphene DTY low-elastic yarn is obtained by adding 0.1-16 wt.% of white graphene to a polyester polymer by melt spinning. USE - Anti-bacterial heating velvet blanket. ADVANTAGE - The anti-bacterial heating velvet blanket helps to reflect good warmth retention, softness and excellent hand feeling, exhibits ideal antibacterial heating, anti-mite, anti-static, far-infrared and anti-ultraviolet functions, and fully reflected the technical effect. DETAILED DESCRIPTION - Anti-bacterial heating velvet blanket comprises a face weave and a bottom weave. The raw material of the surface structure is 50-300 D/0.39-2.7dtex drawn textured yarn (DTY) low-elastic yarn containing graphene. The raw material of the bottom structure is polyester filament with a specification of 50-150D containing 35-20 wt.%. The mass percentage of the raw material of the dough structure in the fabric is 65-80 wt.%. The mass percentage of the raw material of the dough structure in the fabric is 65-80 wt.%. The graphene DTY low-elasticity yarn is obtained by adding 0.1-16 wt.% white graphene masterbatch to polyester chips by melt spinning. The graphene DTY low-elasticity yarn is obtained by adding 0.1-16 wt.% gray-black graphene masterbatch to polyester chips by melt spinning. The graphene DTY low-elastic yarn is obtained by adding 0.1-16 wt.% of white graphene to a polyester polymer by melt spinning. The graphene DTY low-elasticity yarn is obtained by adding 0.1-16 wt.% gray-black graphene to a polyester polymer through melt spinning. An INDEPENDENT CLAIM is included for a method for preparing anti-bacterial heating velvet blanket, which involves: (A) selecting the raw material for the dough texture and the raw material for the bottom texture; (B) using DTY low-elastic yarn with a specification of 50-300D/0.39-2.7dtex containing graphene as the raw material for the surface structure; (C) using polyester filament with a specification of 50-150D containing 35-20 wt.% as the raw material of the bottom structure, the mass percentage of the raw material of the dough structure in the fabric is 65-80 wt.%, the mass percentage of the raw material of the bottom structure in the fabric is 35-20 wt.%; (D) obtaining the graphene DTY low-elastic yarn by adding 0.1-16 wt.% by mass graphene masterbatch to polyester chips and then melt-spinning it or polyester polymer is obtained by adding 0.1-16 wt.% graphene by mass percentage and melt spinning; (E) obtaining the raw materials of the dough and the bottom texture; (F) warping the graphene-containing DTY low-elastic yarn as the raw material of the surface structure and the polyester filament as the raw material of the bottom structure separately by a warping machine; (G) using GL1, GL2, GL5 and GL6 are used for DTY low-stretch yarns to draw in polyester filaments, and polyester filaments are fully worn, the warping is a low-speed warping and is controlled in sections by a tension ring to obtain a pan head, the warp knitting machine uses the bottom yarns GB1, GB2, GB5, and GB6 to knit the bottom weave of the pan head; (H) transferring the GB3 back and forth through the latch needle to the bottom weave; (I) obtaining the antibacterial heating felt gray cloth with a wool height of 2-10 mm; (J) slitting the antibacterial heating carpet gray fabric by slitting machine to obtain slitting gray fabric; (K) using the brushing machine to brush the sectioned fabric and controlling the traveling speed of the sectioned fabric; (L) using a two-roll ironing machine to iron and control the speed of the slitting gray fabric during ironing; (M) cutting the floating hair by the shearing machine to obtain the white gray cloth; (N) subjecting the white gray fabric to hot-air stenter setting by a hot-air stenter setting machine; (O) controlling the temperature and cloth speed of the hot-air stenter setting to obtain the gray cloth to be printed; (P) printing the printing color paste on the gray fabric to be printed by the printing machine to obtain the printed fabric; (Q) ring steaming the printed cloth by a ring steaming machine and controlling the ring steaming temperature and cloth speed to obtain a fixed-color printed gray cloth; (R) washing with water and softening, using a washing machine to wash the solid-color printed gray fabric with sodium hydroxide; (S) using a softening agent and finishing agent for softening treatment, and then dehydrating to obtain the gray cloth to be dried; (T) shaping the hot air stenter setting machine will and drying the to-be-dried gray fabric and dropping it into the cloth car; (U) controlling the cloth speed and setting drying temperature to obtain the cloth to be cut; (V) using the raising machine to cut the hair to be ironed; (W) pulling the parts of the front suede to the back; (X) brushing and ironing with the integrated brushing and ironing machine to obtain the double-sided suede fabric; (Y) heat setting the double-sided fleece gray cloth, controlling the heat setting temperature and cloth speed; and (Z) winding to obtain a new type of antibacterial heating felt.
