Abstract:

In order to develop industrial tubular fabrics that meet market demand, a Y-shaped three-way tubular knitted fabric was engineered by using a computerized fully-fashioned double-needle-bed flat knitting machine, which was taken as an example to study the forming method of fully-fashioned tubular fabrics and the knitting process parameters. Fully-fashioned needles were used to narrow and widen the tubular fabric by transferring loops of the front and back needle beds while knitting the cylindrical shaped fabric. By changing the transverse width of the fabric, the Y-shaped three-way pipe can be knitted fully-fashioned. When designing, the three-dimensional structure of the Y-shaped three-way pipe was tranformed into a two-dimensional shape, and according to parameters such as size, fabric density, knitting direction and the angle between pipes, the knitting process was designed and calculated. The results show that the angle between the Y-shaped three-way fabric pipes is determined by the knitting-to-narrowing ratio. The larger the knitting-to-narrowing ratio, the greater the angle between the pipes. The accuracy of the calculation formula and the feasibility of the design method were verified by producing Y-shaped three-way pipe fabrics with two different angles, employing different pipe diameters and fabric densities.

Key words: Y-shaped three-way pipe fabric, fully-fashioned, knitting process, narrowing by transferring loop, knitting-to-narrowing ratio
