TABLE 3 Table 3
Referring to table 3, it is apparent from the comparison of the data of examples 1 to 3 and comparative examples 1 to 4 that in order to distinguish polyester fibers from nylon fibers and manufacture flannelette with good elasticity, the nylon fibers are modified to attach a release layer on the surface of the nylon fibers, and then the modified nylon fibers are vacuum coated to prevent the metal film from directly contacting the nylon fibers, so that the metal film is prevented from damaging the nylon fibers, and meanwhile, a plating remover is used in the dyeing process of the flannelette, and the plating remover can remove the metal film on the flannelette, so that the color is more easily dyed on the flannelette, the modified nylon fibers and the polyester fibers are more tightly interweaved, and the elasticity of the flannelette is improved.
The comparison of the data in reference examples 3-5 shows that, as the vacuum coating modified nylon fiber on the flannelette is provided with the coating layer, the dye is not easy to dye the modified nylon fiber, so that gaps are easy to exist between the modified nylon fiber and the polyester fiber, and therefore, a coating remover is added into the dye, and the coating remover removes the aluminum oxide of the coating layer, so that the modified nylon fiber and the polyester fiber can be mixed and woven more stably, and the elasticity of the flannelette is improved.
With reference to the data comparison of example 3 and examples 6-8, when the mass of the dimethylsiloxane, the polystyrene and the lecithin are in a specific proportion, the release layer attached to the nylon fiber is more flexible, so that the elasticity of the modified nylon fiber is effectively improved, and the rebound rate of the modified nylon fiber is further improved.
The comparison of the data of the reference example 3 and the data of the reference examples 9-11 shows that the heating temperature is controlled during the dyeing treatment, so that the coating layer of the vacuum coating modified nylon fiber is heated, the falling off of the coating layer is promoted, the close fit between the modified nylon fiber and the polyester fiber is facilitated, and the elasticity of the flannelette is improved.
The comparison of the data of the reference example 3 and the data of the reference examples 12-13 shows that the thickness of the coating layer can effectively improve the brightness layer degree of aluminum at 10-20 mu m, and meanwhile, the adhesive force of the aluminum coating is improved, if the thickness of the coating layer is thicker, the metal film does not react completely in the dyeing process, so that gaps exist between the modified nylon fibers and the polyester fibers, and the elasticity of flannelette is reduced.
Referring to the data comparison of example 3 and examples 14-16, when the mass of thiourea, acetic acid, benzoic acid and glycerin is in a specific proportion, the flannelette is soaked in the dye, and the aluminum film after vacuum coating is dissolved in the dye liquor, so that aluminum ions are attached to the flannelette, the protection effect is achieved on the flannelette, and the flannelette has a better antibacterial effect.
