Description

[Detailed description of the invention] laminated web The present invention relates to a laminated web intended for use as a rolled towel. do.

Conventionally used in hand-wiping devices, but manufacturing costs are extremely high and laundry costs are high. For many years, there has been a need for an alternative material that performs the same function as cotton towels, which require a lot of water. cotton Numerous projects were attempted with the aim of producing paper rolls suitable for roll replacement. . By the way, the main defect that occurs when these products are used is especially when exposed to humidity. In this case, it was extremely easy to tear. A cotton roll towel that can be loaded by unwinding. This is the reason why good results were not obtained with paper rolls in alternate use. It depends. Well, when the towel is torn, the rewind operation is done by the administrator. This necessitated disassembly of the towel device that had to be performed. for this purpose The main qualities required for paper products are high absorbency and strength.

The absorbency of the product according to the invention can be determined, for example, by the type used in the production of kitchen paper towels. The formula is ensured by the presence of the 02 layer tissue paper. Tighten the paper towel before use. In other words, when the user wipes their hands with this towel, the two-layer web is Holes are glued on both sides of the plastic paper. This film has a wet web. When it gets wet, it quickly and uniformly transmits moisture throughout its thickness. These two layers of paper not only maintain the integrity of the web, but also Ensure full utilization of the indicated absorbency.

A condition that must be particularly taken into account when using rolled towels is that the towel is generally The moment you are drawn out of something, you receive an extremely strong force. the user uses his/her hand As long as you grab the towel for wiping, then the towel Needless to say, most of the force applied to the orr is applied to this band. We The plastic film reinforcing tape along both edges of the board is a special feature. This must be to increase the resistance when the web becomes moist. child These tapes can withstand a certain amount of force, thus preventing tears that occur at both edges. prevents the eyes from propagating across the width of the web.

The present invention essentially consists of perforated plastic film layers over the entire surface between them. It consists of two layers of tissue paper inserted with Parallel reinforcements are provided between the tissue layers on both edges of the web. We propose a laminated web that is prepared and intended to be used as a rolled towel I'm going to do it. Making the middle layer of a plastic film made of non-woven material preferable.

Although these tapes gain great tear resistance, these tapes , especially the extremely strong force that is suddenly applied at the moment the roll towel stop mechanism disengages. The web cannot be completely protected against the effects. to withstand similar physical effects , several special reinforcing films are oriented parallel to the longitudinal direction. Once at least one of them passes the inside edge of their reinforcing tapes, Although preferably extending in a band immediately adjacent to the tape, it They can be incorporated into a web along their edges.

Embodiments of the present invention will be described below by way of example with reference to the accompanying drawings.

FIG. 1 is a plan view parallel to the web, and FIG. 2 is a schematic cross-sectional view of the web.

The web consists of two layers of crimped tissue paper 1 with a non-woven perforated fiber between the layers. Lum layer 2 is adhered. The plurality of plastic film reinforcing tapes 3 are The web is placed over the edge of the can. A plurality of reinforcing films 4 are taped at the same time. The strips of web which are also adjacent to those tapes in the zones covered by It is also established in the area. The various parts that make up this web are fixed with adhesive. has been established.

Both outer layers of the tissue paper 1 to be crimped are made of tissue paper with suitable texture and absorbency. It can be made from anything. Each layer should preferably have a minimum basis weight of 15 f/m” and a maximum of 80 t/m”, the preferred weight being 26t/m”.

The plastic film intermediate layer 2 to be perforated consists of between A and 159/m" It will suitably be constructed by a polypropylene film with a basis weight.

The choice is Heku IJ Nil (registered trademark name) manufactured by MySe Company. Preferably, the sufurinil is reinforced by polyamide filaments and Made of polypropylene film with a basic weight of 11 t/m, embossed It is processed and then stretched to create perforations 2a to obtain the required open structure.

This intermediate layer can be fabricated using a separate plastic film as well as by a direct spinning process. These materials can be made into non-woven or wrought fabrics to meet the required drapability and As long as it is soft, it can be made.

The function of those reinforcing tapes 3 is to maintain the integrity of the edges of the towel and therefore to incorporate it into the yarn. It also prevents rupture in the edge area. polypropylene, polyethylene Soft plastic scrims made from polyester, polyamide and polyester Alternatively, various materials such as films can be used as tapes, which They will have basic types 18 and 20 t/m” according to the properties of the material. . Those tapes can be similarly combined with reinforcing filaments; however, preferred The new material is assembled with polyamide reinforcing filaments with a basis weight of 15 f/m2. It is a polypropylene film.

The width of the tapes decreases as they reduce the softness and feel of the towel. It is important that the strength of the tape is sufficient to carry out the reinforcing action of the tape. Width 200+ The width of the tape preferably does not exceed 40'NII for a web of More preferred would be a length of 5° or less, for example 25 m.

As previously mentioned, the zone where the user grips the towel, especially the thumb, usually rests on it. It is important to reinforce the web with bandwidth. Use a relatively wide tape In order to circulate, the reinforcing yarn in the form of multifilament yarn is placed in a section approximately 60m5 wide. 5 in the direction of the web on each of the edges. in the edge band of the web The number of threads 4 installed in the G string varies depending on the material of which the threads are made and the degree of reinforcement required. will do. Although natural fibers such as cotton can be used as well, threads are made from plastic. Preferably, it is made of a fiberglass material, especially polyester multifilament. same belt Yarns belonging to region 5 can be used, for example, a combination of polyamide and polyester yarns. Therefore, they can be different from each other. In a preferred embodiment of the invention, zone 5 of class 6 is , 5 polyester multifilament yarns 280 Y / 1000 m and and 4 polyamide multifilament yarns 470? / Consisting of 1000m Ru.

The threads are of the same material but can also be made according to different diameters. Ru.

A thread 4, shown in Figure 2, is embedded beside the film layer 2 facing the tape 5. However, those threads are also on the same side of this layer 2, in this case the tape It can be on both sides of the edge covered by 6. The web is compensated across its width. If the strong thread is provided, the covering part of the reinforcing thread is also a zone that the user can grab to dry his/her hands. Preferably, it is limited only to bands equal to .

These tapes and threads may be made of a suitable material such as polyvinyl acetate (PVC). Cover and combine with adhesive. This adhesive is applied by an adhesive roller. applied to layer 2 and tape 3. Thread 4 can be applied by passing it past the adhesive. I can do it.

If the web forming the rolled towel is made from a wider web, e.g. It will be understood that At regular intervals over the entire width of this starting part The tape and thread provided are in this case required on each of the two edges of the final product. It will be twice as wide. For finishing, a simple cut in the center of the tape removes the wafer. You can make 8 rolls using the bu.

The breaking resistance of the towel made according to the method according to the present invention is 100 kg in the entire width. can reach extremely high standards.

Certain Example Webs Made According to Preferred Structures and Starting from Preferred Materials 111i 200 m webs were made based on the invention and their outer layer is formed from two sheets of absorbent crumpled tissue paper with basic shape ji2&5f/m'', The middle layer of it is a material made by the Begince company, Sufrinil (registered trademark). ) is made of. Sufurinil with a basis weight of 11 f 7 m” is a polyamide Consisting of polypropylene film (9590) reinforced by domed yarn (590) The material is then embossed and then stretched to create the required open structure. This lamination The body is reinforced with multiple tapes and threads that extend toward the web. PVA adhesive dry weight 91/In2 The adhesive is applied to the film and tape with a roller. So These threads are passed through a bath of adhesive and are similarly glued together. 2.51 width tape are facing each other on each side of the film. These tapes Basic type 1 Constructed from polypropylene film with i154/m2. 9 maltifs The filament reinforcing yarns were planted at intervals on both sides of the web over a width of approximately 60 m. has been done.

Total basic weight 78 and 85? The finished web, which is between 7m”, weighs 80kg. Indicates the maximum strength that can be broken by a traction force of degree. Excellent tearing in the width direction While providing strength, the reinforcing threads provide good protection against breakage in areas that are normally gripped by the user. Assuring protection for the web.
