Embodiment 1
[0017] 1) Warp-knitted mesh cloth: use a weft-inserted warp-knitting machine to warp-knit the warp and weft in full-width weft-insert, and weave it into a mesh fabric. The warp is 30D 24F polyester FDY, and the weft is 100D 48F polyester DTY;
[0018] 2) Heat setting and finishing: under tension, use a slightly higher temperature than the subsequent process to prevent the fabric from shrinking and deforming. Dry heat setting is used to enter the warp knitted mesh into the domestic model M-751, or M-751A needle clip chain heat setting machine, overfeed 2 ~ 4%, carry out clip tentering, and then enter the warp knitted mesh cloth of the tenter into the heating zone with a temperature of 180 ~ 210 ℃, heat for 2 ~ 15 Seconds, then cool the cloth to a temperature less than 50°C and drop the cloth.
[0019] The mesh fabric after the above heat treatment is added into the treatment bath and finishing bath used in the dyeing and finishing process of the fabric, such as flexibilizer, pe...
Embodiment 2
[0023] 1) warp-knitted grid cloth: warp and weft full-width weft-inserted warp-knitting with weft-inserted warp-knitting machine is used to weave into mesh fabric, the warp uses 50D 48F acetate fiber, and the weft uses 60D 70F polyurethane fiber;
[0024] 2) Heat setting and finishing: This step makes the fabric shape relatively stable and fixes the overlapping parts of the warp and weft of the mesh cloth. The thermoplastic fiber fabric will generate internal stress during the weaving process, and it will be affected by the humidity, heat and external force in the dyeing and finishing process. Under the condition that wrinkles and deformation are prone to occur, dry heat setting is adopted, and the warp knitted mesh cloth is fed into the dual-purpose needle plate cloth clip type, and the overfeed is 2 to 4%, and the needle clip tenter is carried out, and then the warp of the tenter The woven grid cloth enters the heating zone with a temperature of 180-210°C, heats for 2-15 seco...
Embodiment 3
[0029] 1) Warp-knitted mesh cloth: use a weft-inserted warp-knitting machine to warp-knit the full-width weft-inserted warp and weft threads, and weave them into a mesh fabric. The warp threads use monofilaments made of 45D 40F polyvinyl chloride, and the weft threads use 100D 80F glass fiber;
[0030] 2) Heat setting and finishing: This step makes the fabric shape relatively stable and fixes the overlapping parts of the warp and weft of the mesh cloth. The thermoplastic fiber fabric will generate internal stress during the weaving process, and it will be affected by the humidity, heat and external force in the dyeing and finishing process. In this situation, wrinkles and deformations are prone to occur. Put the warp-knitted mesh cloth into the dual-purpose needle plate cloth clip type, overfeed 2 to 4%, carry out the needle clip tentering, and then put the warp-knitted mesh cloth of the tenter Enter the heating zone with a temperature of 180-210°C, heat for 2-15 seconds, then...
