Design And Development Of The One-piece Venetian Blind Fabric With Jacquard Effects

According to the survey of curtain market,the venetian blinds today mainly formed by cementing three layers of fabric,it means that applying glue to the upper and middle layers,middle and lower layers,and achieve glue bonding between the three layers.The production process is cumbersome,complex and has a low environmental performance.Therefore,the design of simple and green jalousie has a broad and urgent market.The related research of the three-dimensional fabric provides a theoretical basis for one-piece venetian blind fabric with jacquard effects.This issue is to overcome the deficiencies of the prior blinds.Use CAD digital design technology,weave design,electronic jacquard weaving technology,designing a style of one-piece Venetian blind fabric with jacquard effects.Starting from the research of one-piece venetian blind fabric with jacquard effects,flattening three layers into flat fabrics,design the pattern and structure of the fabric by using a plurality of sets of digital jacquard design and production technology,design reasonable weft arrangement,finally weaving the fabric with a certain thickness in the Electronic jacquard machine.Through the post processing technique,cut the float line.After stretching,we get the three-layer jacquard curtain fabric with shutter effects.the upper layer and the lower layer are blind fabric with jacquard effects connected by a photic stripe.Compose the curtain with the inner rod,pull rope,window box and a lower rod.The fabric has a light transmission effect when the rod is not pulled and three layer fabric get close together,The fabric has al shading effect when rod is pulled,So that the up layer and the lower layer can move up and down and forms a complete shading effect.Three units are designed to the fabric from the warp direction,each unit consists of the consolidation area 1,the shading area,the consolidation area 2,and the photic area,and these four areas are designed as three layers structure.The upper layer and the middle layer of the consolidation area 1 are designed as warp single weft triple,the lower layer and the above two-layer structure are designed as hollow woven fabric;three layers of the shading area are designed as hollow woven fabric,the middle layer and the lower layer of the consolidation area 2 are designed as double-layer structure with surface warp stitching,the upper layer and the two-layer structure below are designed as warp single weft triple;the upper layer and the middle layer of the photic area are designed as hollow woven fabric,the lower layer consists of wrap float line,and wrap float line will be cut after the weaving process.5 groups of weft were designed at the ratio 1:1 in the consolidation area 1,the shading area,and the consolidation area 2,weft A and weft D used28.1tex×2 rayon(white),weft B and weft C used28.1tex×2 rayon(orange),weft C used 2.2tex polyester(white).Weft C and weft F were designed in the photic area,weft F used 2.2tex polyester(white).There are 2 groups weft The warp arrangement of three layers is 1:1:1.Wrap A,wrap Band wrap C were designed as 2.2tex polyester(white).In order to prevent the difference of warp shrinkage,there will be three changes for the order of the warp every three laminae.Finally,conduct Jacquard process design and then weave on the loom.Thus we get a three-layer fabric,which is integrated with the transparent layer and the lightproof layers.Through the post processing technique,cut the float line.After stretching,we get the jacquard curtain fabric with shutter effects.Compose the curtain with the inner rod,pull rope,window box and a lower rod.Whereby,we get one kind of one-piece Venetian blind fabric with jacquard effects,which enriches the types of curtains.
