  • Patent number: 8733075
    Abstract: A process is described wherein pile yarn is woven with cotton weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve the PVA fibers. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn, corresponding to an increase in the air space in the pile yarn. By increasing the air space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels. The present invention further relates to pile yarn in terry woven fabric (warp yarn), or weft yarn, in the case of flat fabrics.

  • Patent number: 4768814
    Abstract: The carpet-knotting apparatus comprises a head (1) solid with a guiding rod (7) and carrying a buckle (8). It also comprises a movable unit (12 to 16) composed of a control handle (12) made in one piece with a bar (13), to which two hooks (15, 16) are jointed. A ball (27) is located between the rod (7) and the handle (12). That ball is girled by the edges of an opening (29) of a sleeve (28), which a spring (30) keeps in contact with a ring (22). That ring forms part of a releaser (20) which extends through head (1). At rest and when the buckle (8) enters the canvas (32, 33, 34), the sleeve (28) wedges the ball (27) between the notch (24) and the wall of the groove (25), thereby locking the movable unit with respect to the head (1). When the buckle (8) fully crosses the canvas, the releaser (20) is pushed by the latter. The ring (22) moves the sleeve (28) which conceals the ball (27) on the bottom of the notch (24).
