An embodiment of the present invention is an illuminated stop sign for allowing pedestrians to control traffic. The system comprises a fixed support assembly; a pedestrian activated mechanism; a timer set for a predetermined period of time when the pedestrian activated mechanism is activated; and an octagonal display nonremovably mounted to the fixed support assembly comprising a backlight within the display and a display surface comprising a word 'STOP' visible when the backlight is illuminated and substantially not visible when the backlight is not illuminated, the backlight being illuminated until the predetermined period of time is expired.

A method for making a meltblown liquid laundry detergent sheet provides increased detergent solids by incorporating powdered liquid detergent ingredients into the meltblown web during the formation of the meltblown web. Thereafter the balance of the liquid detergent formulation is incorporated into the web by saturating the web with a solution containing the balance of the liquid detergent ingredients and drying.

Meltblown laundry web comprising powdered detergency enhancing

There has been provided a recreped absorbent product manufactured by forming a web from an aqueous stock, drying the web to a selected consistency and creping one side thereof. The creped web is then conveyed at a selected rate for drying and recreping on the same side. The web moisture consistency, draw speeds, crepe angle and nip pressures as well as crepe adhesive qualities are controlled parameters.

Recreped absorbent products and method of manufacture

High-strength tissue products are made with two outer tissue plies thermally bonded to a center layer of meltblown fibers.

Method for incorporating powdered detergent ingredients into a meltblown

A multi-layered meltblown web contains a sufficient amount of condensed liquid detergent to wash a load of laundry. The layered construction utilizes high melting temperature materials in the outer layers which provide protection against melting of the less expensive, lower melting temperature inner layer when the product is exposed to abnormally high dryer temperatures.

Multi-layered cleaning product

A high melting temperature meltblown web, such as a polyester meltblown web, contains a sufficient amount of condensed liquid detergent to wash a load of laundry and does not exhibit an objectionalbe sticky feel.

High melting temperature laundry detergent sheet

A method for making a meltblown liquid laundry detergent sheet provides increased active detergent solids by spraying a solution of detergent enchancers of the liquid detergent formulation into the meltblown web during the formation of the meltblown web. Thereafter the balance of the liquid detergent formulation is incorporated into the web, which is then dried.

Incorporating detergent into a meltblown laundry detergent sheet via the

Tissue comprising a matrix of nonwoven fibers having a basis weight generally in the range of about 25 to 50 gsm. The matrix is a meltblown web having incorporated therein staple fibers. The combination provides highly-improved tissue properties as well as strength and absorbency required for many tissue applications. The tissues may be formed by a conventional meltblowing process involving extrusion of a thermoplastic polymer as a filament in air streams which draw and attenuate the filaments to fine fibers, having an average diameter of up to about 10 microns. The staple fibers may be added to the air stream, and the turbulence produced where the air streams meet results in a uniform integration of the staple fibers into the meltblown web. The matrix may contain from about 30 to about 80 weight percent polymer and have a subjective softness rating of at least about 10.

Lightweight nonwoven tissue and method of manufacture

A method of laminating a two-ply product wherein the plies are laminated to one another and adhered to a creping surface in the same pattern. A first ply is directed about a patterned pressure and imprinting roll and laminating adhesive is applied to the first ply in a pattern corresponding to the pattern of the pressure roll. A second ply is brought into contact with the first ply, and the composite web is adhered to a creping surface with a creping adhesive at a nip formed between the creping surface and the patterned pressure roll. The composite web is creped from the creping surface in a pattern corresponding to the pattern of lamination. When creped, the densified laminated/creped portions add strength to the resulting product, while between the densified areas the webs are not adhered to one another and the void areas therebetween provide sites for water absorption. In a second embodiment, an endless fabric or belt may be directed about a smooth pressure roll, such that the knuckles of the fabric laminate the plies to one another and adhere the composite web to the creping cylinder in the same pattern.

Laminated, creped tissue and method of manufacture

A process for directly forming multiple layer web, and creping such webs to provide absorbent, soft and bulky, creped tissue. The process produces a laminar fibrous formation with outer layers of strongly bonded fibers separated by an intermediate central section of weakly bonded fibers, which outer layers are creped such that the crepe in one outer layer is independent of the crepe in the other outer layer. The process utilizes a multiple slice inlet with different fiber stock supplied via the inlet to form the weakly bonded central layer of the fibrous formation; the base formation is subjected to two creping operations: one side of the fibrous formation is adhered to the surface of a dryer and creped therefrom, the once-creped web is inverted, and the other side adhered to the surface of a dryer and again creped therefrom, producing finely creped, soft and bulky outer surface layers of strongly bonded fibers which are capable of delamination, each layer shearing away from the other during the creping operations because of the weakly bonded intermediate fibrous section and the final product simulating a two ply tissue in bulk and softness while having been formed as a single ply.
