Abstract:
A method for crimping yarn, comprising the steps of:feeding the yarn into a channel of a compaction chamber so as to impart a substantially uniform crimping to the yarn; and pre-setting the substantially uniformly crimped yarn by passing the crimped yarn from the compaction chamber into a pre-setting and guiding chamber defining a passage through which the crimped yarn passes, the passage having a cross section greater than that of the channel of the compaction chamber such that a free space is defined between at least one side of the crimped yarn and an adjacent wall of the passage, and wherein a pre-setting fluid is fed into the passage of the pre-setting and guiding chamber to pre-set the crimping of the yarn and to act on said at least one side of the crimped yarn so as to guide the yarn's progress through and out from the passage.
