    Abstract: A process for producing yarns that have enhanced resistance to unraveling and linting. The yarns are moved along guides through a needle loom where a series of needles engage the yarns. This engagement of the yarns by the needles causes the fibers of the yarns to become intermixed.

    Abstract: This invention generally relates to the production of a composite yarn or non-woven strand wherein a core of super absorbent fibers or polymers (SAP's) having a swell factor of approximately 25% and greater are encapsulated by a nonwoven membrane of defined porosity. The membrane is then sealed in a fashion to generally deter or prevent the SAP material from migrating out of the core as water is freely absorbed and desorbed from the composite yarn structure. The strands of yarns or strips of non-woven material are subsequently constructed into an open or unorientated fabric formation. When used as a subterranean fabric, structure or material, the resultant fabric structure retains moisture while permitting normal root growth and allowing excess water to pass through and beneath the fabric while facilitating movement of water from lower levels to the surface.
