Design And Development Of Functional Bra Mold Up Composite Fabric

With the pursuit of a healthy life,women bra model cup products are becoming more comfortable and functional.The composite fabric based on graphene cellulose fiber as discussed in this paper has certain function,great heat and humidity comfort and satisfies the market demand.Graphene cellulose fiber as a raw material makes the bra functional,at the same time,mixed with different amounts of phase change fiber,it improves the comfort of the bra cup.The composite fabric was prepared by a series of technologies.Firstly through opening,blending,carding,web forming and spun-lace reinforcement technology to prepare spun-laced nonwovens,then mixed with 3D upright fabric by chemical bonding to get the final composite fabrics.During the preparation of spun-laced nonwovens through reinforcement technology,effects of different surface densities(60g/m2、80g/m2、100g/m2)and different fiber ratios(0%/100%、20%/80%、50%/50%、80%/20%、100%/0%)on the properties of spun-laced nonwovens were analyzed.The comfort and functionality of the 3D upright fabric and composite fabrics were tested,the differences in fabric performance of the fabric were analyzed and compared before and after the composite material attained.This paper obtained the following results from the above studies:(1)The entanglement coefficient of mixed spun-laced nonwovens increases with the increase of the content of graphene cellulose fiber,and the tangling effect is further improved.When the ratio of graphene cellulose fiber to phase change fiber is 80%/20%,the entanglement coefficient of spun-laced nonwoven is at the highest level,the wicking height is high,the mechanical performance is at the best level,most breathable and softer.By testing the far-infrared properties of spun-laced nonwovens,it was found that when the content of graphene cellulose fibers in spun-laced nonwoven exceeded 50%,spun-laced nonwoven had far-infrared properties.(2)On testing the performance of 3D upright fabric,we found it has great air permeability,good warmth,certain anti-UV performance and feels soft.But the fabric’s biggest limitation is that the fabric dimensional stability is very poor.(3)The strength of the composite fabric is greatly enhanced,the elongation is reduced,and the dimensional stability of the composite product is enhanced,which solves the problem that the 3D upright fabric cup is easy to collapse.The permeability of the composite fabric is lower than that of the 3D upright fabric,but it still meets the standard requirements of bra cup.Vertical wicking height is raised.The fluffiness is reduced,the elastic recovery is reduced,and it is easy to be compressed.The thermal resistance value of the composite fabric is increased,the warmth retaining ratio is improved.In short,the heat and moisture comfort of the composite fabric is improved compared to3 D upright fabric.(4)After the composite,the composite fabric UV protection performance has been further improved,far more than UV protection standards.For the far-infrared functional test of the composite fabric,we found that in order to ensure the far-infrared performance of composite fabrics,the weight of the spun-laced nonwoven fabric used for bonding of the composite fabric should be between 60-80g/m2,and the graphene cellulose fiber content should be more than 50%.For the antistatic properties of composite fabric,it was found that when the graphene cellulose fiber content of spun-laced nonwoven for the composite fabric reached or exceeded 50%,antistatic met the A-level requirements.The composite fabric by chemical bonding functional spun-laced nonwoven and 3D upright fabric not only solves the problem of 3D vertical fabric cup easy collapses,improves the heat and humidity comfort,but also gives its far-infrared performance,antistatic properties,anti-ultraviolet radiation performance which improves its functionality.When it is applied to bra mold cup products,it meets the safe,healthy and comfortable women’s bra needs.Moreover,this also provides good reference for the application of graphene cellulose fibers in textile applications.
