Abstract
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.
Claims14
An improved nonwoven resistant to slippage comprising:
- a nonwoven substrate having top and bottom surfaces, at least one surface of said nonwoven substrate being coated with microcapsules containing an adhesive,
- said microcapsule coated nonwoven having an average drag force of at least 250 grams as per the method described in Example 1.
An improved laminate for forming disposable footwear for health care or clean room environments comprising:
- a first covering layer of a fractured plastic film at least one layer of a nonwoven web material,
- said first covering layer of fractured plastic film being coated with microcapsules containing an adhesive, said microcapsule coated plastic film having a drag force of at least 250 grams as per the method described in Example 1.
An improved substrate for forming disposable footwear for health care or clean room environments comprising:
- a substrate having at least one layer of nonwoven material,
- at least one surface of said substrate being coated with microcapsules containing an adhesive, said microcapsule coated substrate having a drag force of at least 250 grams as per the method described in Example 1,
- said laminate being folded along a longitudinal axis to form two mirror image panels, the covering layer coated with microcapsules containing an adhesive selected as the exterior,
- said mirror image panels being joined together at outer edges by a continuous seam to form a shoe covering except for an opening being provided for the wearer's foot, said edges forming the opening being provided with a resilient material to snugly close the opening around the wearer's foot.
