75D/72f and 100D/96f polyester yarns were knitted to develop three kinds of fabrics with different densities (large,medium and small) on circular knitting machine (gauge E18). It was found that the strength of the fabrics increased with theincrease of loop density, and the initial modulus of the fabrics also increased. In order to obtain better strength and lowerinitial modulus, the washing and heat setting process of the fabric were studied and explored. The strength and initialmodulus of the three density fabrics of the two yarn specifications decreased after pre-washing. Finally, the lowest initialmodulus (0.36 MPa at warp direction and 0.22 MPa at weft direction) were found in sample (sample no. 3-3) made of 75Dfilament in longest loop length under 140 oC heat setting. The weft strength and warp strength were 9.54 MPa and 5.28 MParespectively.

The Moisture Management and Drying Properties of Weft Knitted Plating Fabrics
Qing Chen,Dahua Shou,Rong Zheng,Jintu Fan,Xianfu Wan,Bailu Fu,Pibo Ma 한국섬유공학회 2020 Fibers and polymers Vol.21 No.6
The six types of weft knitted fabric in plating structure were made by cotton, polypropylene and polyester withdifferent number of filaments. The fabrics were tested by moisture management tester, vertical wicking and drying test. It wasfound that the large water absorption difference and the large filament density difference between the inner and outer side offabric could result in the better water absorption and drying ability. The fabric with polypropylene yarn (75D/48f) at innerside and cotton yarn (40 Ne) at outer side had best moisture management property evaluated by MMT. While the fabric withpolypropylene yarn (75D/48f) at the inner side and polyester yarn (75D/144f) at the outer side had highest vertical wickingand drying rate.

In order to improve the moisture management of knitted fabric, double layered structure usually was applied toobtain better moisture management properties, but the thickness of fabric could be increased. To solve this problem, thepartial double layered structure was constructed on the base of single layered structure. Further in order to improve the airpermeability, the mesh structure was also designed. The results show the moisture management of noval structure not onlyhad better one-way transport property but also improve the water vapor and air permeability compared with both single jerseyand double jersey structure. Besides, the effects of ratio of total double layered pattern area to total area, ratio of one doublelayered pattern area to total double layered area, ratio of hollow area to total area, ratio of mesh area to total area on moisturemanagement, water vapor transport and air transport property were discussed. This study demonstrated non-smooth concavesurface with porper unit size could improve the mositure management property and reduce the fabric weight and thickness,and the mesh structure could improve the air permeability but weaken the moisture management property. The results showedthis was an effective solution to balance liquid, vapor and air transportation in a knitted system.
