A method of manufacturing high bulk continuous multi-filament yarn comprises a number of distinct steps. In a first step, a plurality of filaments of polymer are melt spun to form a partially oriented yarn (POY). In a second step, the POYs are drawn and textured to form a draw textured yarn, wherein texturing is carried out in a friction texturing process. Subsequently at least two plies of the draw textured yarn are twisted and/or cabled together and subsequently heat set to obtain the high bulk continuous multifilament yarn.

The invention relates to a method and apparatus for manufacturing carpets with an antique appearance using an automated weaving machine. The system integrates advanced control of warp tension, specialized pile yarn, and a unique reed and lancet assembly to replicate the randomized wear patterns, variable pile heights, and textural intricacies characteristic of aged carpets. A blend of synthetic and natural fibers undergoes a proprietary crimping, spinning, and two-stage dyeing process, producing multicolored yarn with pseudo-random shrinkage properties. Warp threads are precisely positioned using weighted beams and tiered lancets, enabling the creation of areas with zero and non-zero pile heights, separated by gradual transition zones. The resulting carpets exhibit high aesthetic authenticity and structural durability. A chi-squared statistical process ensures the randomness of worn patterns, optimizing the antique effect. The invention provides a scalable and efficient solution for producing affordable carpets that closely mimic the look and feel of genuine antiques.
