Abstract

A laminated web for use as a roll towel comprises a sheet of plastics scrim 2 between two layers of tissue paper 1. The edge portions of the towel are reinforced with plastics tapes 3 and threads 4. <IMAGE>

Description

SPECIFICATION Laminated web The invention relates to a laminated web for use as a roll towel.
There has long been a need for a satisfactory alternative to the cotton towels which are traditionally used in roll towel cabinets but which are very expensive to make and which are costly to launder.
Attempts have been made to produce a roll of paper to replace the cotton rolls. The major drawback with rolls in the past has been their susceptability to rupture, especially when wet. Paper rolls have not, therefore, been satisfactory for use in cabinets where the used roll is re-reeled, since, if the towel breaks, the re-reeling can only be re-started by a janitor who must open up the cabinet. The main requirements of a paper product for use in this field are that it is highly absorbent and that it is strong.
Absorbency is provided in the present invention by two layers of tissue paper of the kind used in the manufacture of kitchen paper towel. To strengthen the tissue in use, i.e. when a user is drying his hands on the web, the two tissue layers are adhered to a non-woven perforated plastics film. This film maintains the integrity of the web when wet but also allows water to pass readily therethrough to ensure that the complete absorbing facility of both tissue layers is utilised.
In operation of a roll towel cabinet the towel may be subjected to very high forces as the towel is withdrawn from the cabinet. Since the towel is naturally grasped in the edge portions the majority of the forces act in these regions. In order to give added strength to the regions, especially when wet, plastics film tapes are inclined in the present invention along each edge of the web. The tapes will withstand high forces and prevent the propogation of tears from the edges across the web.
According to the invention there is provided an elongate parallel sided laminated web for use as a roll towel comprising; two layers of tissue paper extending substantially across the web; a nonwoven perforated plastic film layer extending between the layers of tissue paper; and a tape in the form of a plastics film disposed along each edge region of the web between the layers of tissue paper.
Although the tapes will withstand high forces they are not capable of withstanding very high forces which are suddenly applied such as when the stop mechanism in the cabinet dispenser comes into operation. In order to withstand such forces special reinforcing threads extending parallel to the length of the web may be included at least in the edge regions of the web.
An embodiment of the present invention is described below with reference to the accompanying drawings in which: Figure 1 shows a plan view of the web; and Figure 2 shows a diagrammatic section through the web.
The web comprises two layers of creped tissue paper 1 between which is adhered a non-woven perforated film layer 2 of plastics material. Reinforcing plastics film tapes 3 are provided along each edge of the web and reinforcing threads 4 are provided in the region of the tapes 3 and inwardly thereof. The web is held together by means of adhesive. Although the threads 4 are shown in Figure 2 as being on the opposite side of the film layer 2 from the tapes 3 they may be provided on the same side of the layer 2 and in this case may be provided on either side of the tapes 3. The threads may be provided right across the web but preferably are provided in regions extending only partly across the web; these regions being the regions which are grasped by the hands of a user.
A specific example of a preferred web construction and materials is given below.
Example Web width 200mm, 78/m2 weight Tissue: 2 sheets of creped tissue paper each of 26.5g/m2. The base weight of the tissue sheets may range from about 15 - 50g/m2.
Tapes: Polypropylene film with polyamide reinforcing filaments in the machine direction. The tapes have a preferred width of 2.5 cm and have a preferred base weight of 11g/m2 Perforated film layer. This layer comprises SCRI NYL (Registered Trade Mark) manufactured by Beghin-Say s.a. The layer is made from a Polypropylene film (95%) reinforced with Polyamide threads (5 /O) in the machine direction. The film is embosed and stretched to produce the required open structure. The tapes may alternatively be made of any soft plastics scrim.
Threads. The threads 4 are Polyester multifilament threads.
Adhesive (9g/m2 dry) The adhesives comprise PVA and are applied to the layer 2 by rollers and to the tapes 3. Adhesive may be applied to the filaments 4 by running them through an adhesive bath.
It will be understood that the web forming one roll is manufactured from a wider web, e.g. 8 times wider. The tapes and threads are arranged at intervals across the wider web and are of twice the width required in the final product. The web is then cut through the centres of the tapes to produce 8 rolls.
1. An elongate parallel sided laminated web for use as a roll towel comprising; two layers of tissue paper extending substantially across the web; a non-woven perforated plastics film layer extending between the layers of tissue paper; and a tape in the form of a plastic film disposed along each edge region of the web between the layers of tissue paper.
2. A laminated web as claimed in Claim 1 further comprising spaced reinforcing threads running parallel to the length of the web and being pro
