A method of making an embossed air-laid absorbent sheet material includes depositing a dry web of fibers on a foraminous support; compacting the fiber web; embossing the compacted fiber web with an embossing roll provided with a plurality of sinuate bosses radially projecting circumferentially around the embossing roll to provide the fiber web with a functional emboss pattern including a plurality of continuous sinuate compressed regions extending in a machine direction of the fiber web, and bonding the fiber web to produce the embossed air-laid absorbent sheet material. The emboss pattern is operative to preferentially convey sorbed liquid along the plurality of continuous sinuate compressed regions of the fiber web.

Air-laid absorbent sheet with sinuate emboss

Disclosed is a fibrous web which includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.

Process for preparing a non-woven fibrous web

An absorbent sheet made from an air-laid fiber web includes a functional emboss pattern of a continuous (wave-like) shape extending in the machine direction of the sheet. The emboss pattern defines a plurality of compressed regions operative to preferentially convey sorbed liquid away from the point of insult to prevent product failure. The sheet is particularly useful as absorbent core material within a multi-layer absorbent pad. In a further aspect of the invention, there is provided a method of making absorbent sheet utilizing an emboss roll provided with radially projecting circumferential sinuate bosses.

The present invention is a slip resistant nonwoven material. The material can be useful for surgical or clean room environments. The nonwoven is coated with microencapsulated adhesive. The microcapsule coated nonwoven is resistant for slippage. The substrate in preferred embodiments is fashioned into articles such as slip resistant table coverings or protective articles such as footwear.

Slip resistant nonwoven

An improved process for the separation of cellulosic fiber from difficult to process coated and inked paper products is disclosed and claimed. This process readily separates the paper pulp fraction substantially free of contaminants from such waste paper products as single and two side polymeric coated board having wet strength resin, single and two side polymeric coated board having no wet strength resin, single and two-sided glossy printer trimmings, ultraviolet (UV) cured ink coated stocks, and mixtures thereof. Preferred embodiments include a process in an inclined pressure vessel equipped with agitating and rotating means operative to reflux the waste material with respect to the inclined axis of the vessel in the presence of steam and chemical aids for a sufficient period of time so as to bring about repulping and separation of the paper fiber fraction and formation of a contaminant-collecting polymer phase. The recovered paper pulp fraction is suitable as a feedstock in the manufacture of a variety of paper products including paper tissue and paper towel products.

Absorbent sheet material with wave-like pattern

A three ply sandwich structured hydroentangled web is disclosed. The top and bottom plies of this web comprise long synthetic fibers having a fiber length of about 30 to 100 mm and the middle ply comprises cellulosic fibers having a fiber length of about 1 to 8 mm. The middle layer cellulosic fiber can optimally be wholly or partially replaced with short synthetic or other natural fibers having a fiber length of about 6 to 27 mm. These hydroentangled webs are useful in the manufacture of towels, wet wipes, industrial wipes and medical gowns.
