What is rhinestone velvet made of?

　　Rhinestone velvet is composed of rhinestones and flocking cloth paper, so let’s talk about rhinestones is a general term. Rhinestones belong to amethyst. Because the color is milky white, rhinestones are generally divided into domestic and German. The more well-known is Slower Violet. crystal. Therefore, it is generally said that rhinestones can be divided into thick bottom and sharp bottom. Hot rhinestones belong to thick bottom, but there is a sticker on the reverse side. It is necessary to use equipment to heat and scald the object when applying it. The sharp bottom drill must be drilled on the object before the rhinestone position can be drilled. Touched.

　　Flocking cloth paper, also known as electrostatic induction flocking cloth paper, is a production and processing paper made of electrostatic induction flocking cloth technology. The color is gorgeous. Soft and malleable, like a tapestry. After coating the surface of the base paper or only the special position of the pattern design with thermoplastic, the polyester staple fiber (such as plush, polyester, wool fleece, etc.) of various colors will be dyed, the length is 0.2~1.6mm) Embed part of the plating. After the direct current, because of the harm of the magnetic wire, the positive charge is more likely to be concentrated on the top of the polyester staple fiber, so that the standing polyester staple fiber is glued to the base paper.

　　GB/T14272-2011 old national standard anti-drilling and velvet testing is mainly to evaluate the friction method of bladder cloth and fabric anti-drilling and velvet. This kind of test standard cannot truly reflect the down jacket's suture line and needle angle burrowing condition during the whole process of dressing. This is also the reason that the test report meets the standard, but customers still often complain. The GB/T14272-2021 national standard selects the clothing turning box method to evaluate the various possible running cashmere conditions of the entire clothes and pants.

　　The basic principle of the garment turning box method: put all the tested samples into the experimental instrument turning box equipped with silica gel special-shaped balls, and send the silicone special-shaped balls to a certain aspect ratio and impact box according to the constant speed rotation of the rotary box. Sample, simulate the various extrusion, friction, impact and other effects of the tested sample during taking, and calculate the relative total area of ​​the unit

　　According to GB/T31907 test the length of the sample (or jeans, long skirt) L1. Bust size (or hip) L2. Bust size L3. Sleeve fat L4. When adding down to the non-powered hood of the down jacket, the sunshade should be accurately measured After the brim of the hat is folded vertically and shared, the larger total width L5 and the larger aspect ratio L6 of the sun visor.

　　The total area of ​​clothing St=(2L1xL2+8L3xL4+4L5xL6)x10-4.

　　The number of running down roots is Nt.

　　Remove the feathers, feathers and down from the equipment, scrub the vulcanized rubber ball of the opposite sex, close the clothing zippers, remove the collar, and remove the exposed feathers, feathers and down. Carry out the test based on the main test parameters.

　　After 1440 revolutions, remove the tested sample, carefully drill the number of down roots, and calculate the number of down, down and down roots with a length of ≥ 2mm. Add Nt to the number a1 of the inner and outer surfaces of the sample, the number b1 and the number c1 adhered to the surface of the vulcanized rubber special-shaped ball.

　　2. De Calculate the velvet value.

　　De=Nt/St drill down value.

　　The anti-drilling value of the sample, the enterprise is root/m2.

　　When the anti-drilling value exceeds 200/m2. the experimental result is recorded as above 200/m2.
