Abstract:
A pile warp tension control method using a pile warp tension control device capable of adjusting the tension of pile warp yarns according to a weave on a pile fabric loom so as to prevent mislooping due to change of operating mode from a pile weave section weaving mode to a ground weave section weaving mode, said pile warp tension control method comprising:setting a first pile warp tension amount for a pile weave section weaving mode for use in weaving a pile weave section, and setting a second pile warp tension amount for a ground weave section weaving mode, respectively, for use in weaving a ground weave section, said second pile warp tension amount being higher than said first pile warp tension amount;adjusting the tension of the pile warp yarns from said first pile warp tension amount to said second pile warp tension amount in a predetermined period after the change of the operating mode of the pile fabric loom from the pile weave section weaving mode to the ground weave section weaving mode, by gradually increasing the tension of the pile warp yarns from said first pile warp tension amount toward said second pile warp tension amount.
