Jacquard Capacity and Hook Number Configuration
topic
Jacquard machine capacity is specified by the number of independently controlled hooks ranging from 400 hooks in small-format label looms to 10240 hooks in standard silk and upholstery Jacquards and up to 20480 hooks in large-capacity digital Jacquards for wide-width figured fabrics, with each hook controlling one or more warp ends depending on whether single-end or multi-end harness configuration is used, and with larger hook capacity enabling wider pattern repeats and greater design complexity.
Role
Determines the maximum pattern repeat width and design detail resolution achievable on each Jacquard machine, with hook capacity being the fundamental specification that guides machine investment decisions for specific fabric categories, with silk scarf Jacquards requiring large capacity for full-width unrepeated design while upholstery Jacquards use moderate capacity repeated across the fabric width, and with capacity selection requiring balance between design requirement and the capital cost that increases with hook count.
