Abstract
A 2-warp knit, weft inserted fabric having the face thereof calendered to produce a fabric when a PVC film is laminated thereto that has a surface roughness of 2.0 microns or below.
Description
- This Application is a Divisional Application based on U.S. patent application Ser. No. 09/338,416, filed Jun. 22, 1999.
- This invention relates generally to a coated or laminated fabric which can be printed evenly and clearly on both sides and in particular to a calendered weft inserted warp knit fabric for such use in laminated or coated fabrics or applications.
- Prior to this invention, weft inserted, warp knit fabrics were supplied to the customer generally in the condition that it comes off the knitting machine and the customer usually applied any further treatment required by them for their particular use. Warp knit farics with weft inserted yarns therein generally provided a face side which was rough and uneven due to the weft inserted yarns which did not allow good adhesion for a film or other substance to be laminated or coated thereon.
- Therefore the object of the invention is to provide a warp knit, weft inserted fabric which when coated or laminated provides excellent adhesion as well as printability.
- Other objects and advantages of the invention will become readily apparent as the specification proceeds to describe the invention in detail with reference to the accompanying drawings in which:
- FIG. 1 is a schematic representation of the process of treating the warp knit, weft inserted fabric;
- FIG. 2 is a schematic representation of the process to laminate the fabric treated in FIG. 1;
- FIG. 3 is a cross-section of the fabric produced by the treatments shown in FIGS. 1 and 2;
- FIGS. 4 and 5 are schematic representations of the equipment used to measure surface roughness of a fabric;
- FIG. 6 is a table comparing surface roughness of an untreated and a treated warp knit, weft inserted fabric; and
- FIGS. 7 and 8 represent, respectively, a running graph of the measurements made by the equipment of FIGS. 4 and 5 on the untreated and treated fabric.
- Looking now to the drawings and especially to FIG. 1, a roll of warp knit, weft inserted
fabric 10 is shown being processed and taken-up on the surface drivenroll 12. The preferred warp knit, weft inserted fabric is a two bar, 100% polyester fabric having a 70 denier multifilament stitch yarn, a 1000 denier multifilament warp yarn and a 1000 denier multifilament weft inserted yarn. - The
fabric 14 from thesupply roll 10 is supplied over a series ofguide rolls calendering machine 24 wherein the face of thefabric 14 is calendered between theheated steel roll 26 and the rubber coatedroll 28 wherein the weft insertedyarn 74 is crushed to provide a smooth face. From thecalendering machine 24 the calenderedfabric 15 is guided by therubber roll 32 to theinspection machine 34 and then, after inspection, is guided by another series ofrolls up roll 12 driven by thesurface drive rolls - In the preferred form of the invention the face calendered
fabric 15 is taken-up on the take-up roll 12 and delivered to the machine shown in FIG. 2 but obviously, if desired, the face calenderedfabric 15 could be delivered continuously in line with machine in FIG. 2. From theroll 12 the face calenderedfabric 15 is guided into the nip ofheated steel rolls idler rolls thermoplastic film 58 fromrolls 60 to provide the coatedfabric 62 shown in FIG. 3. From the nip ofcalender rolls fabric 62 is taken upon a take-up roll 64 driven bysurface drive rolls - The
fabric 62, as shown in FIG. 3, consists of the outerPVC film layers 58 and the calendered warp knit, weft insertedfabric 15 consisting ofwarp yarns 70,stitch yarns 72 and weft insertedyarns 74. Thefabric 62, in the preferred form of the invention is 19-20 mils thick with each of thefilms 58 being approximately 5 mils thick. This particular fabric is desirably used as a banner fabric which can be printed on both sides due to the evenness or smoothness of the face of the warp knit, weft inserted fabric. - To measure the surface roughness of the face of the calendered warp knit, weft inserted fabric after it has been laminated to the film, the
surface tester machine 76 shown in FIGS. 4 and 5 is used to obtain the data shown in FIG. 6 and the graphs of FIGS. 7 and 8. The surface roughness tester machine illustrated is a KES-FB-4 machine sold by Kato-Tekko Co., Ltd. of Kyoto, Japan. - The
sample 78 of thefabric 62 to be tested is clamped at one end to thewinding drum 80 bychuck 82 and to thechuck 84 at the other end. A transducer (not shown) is hooked to thecage 86 to record the up and down movement thereof as dictated by thefinger 88 as it senses the face of thefabric sample 78 as it moves back and forth thereunder by rotation of the winding drum. - Looking at FIG. 6 the mean deviation in microns of the warp knit, weft inserted fabric before and after calendered as shown in FIG. 1 and treated as in FIG. 2 is shown with the face of the calendered fabric A having a surface roughness of less than 2.0 microns whereas the face of the sample fabric coated without calendering had a surface roughness almost four times greater. Note the difference in amplitude of the face of the non-calendered fabric in FIG. 7 versus that of the calendered fabric in FIG. 8. It is clearly evident that the fabric of FIG. 8 is very smooth which increases the adhesion of the warp knit fabric to the film as well as enhancing the printability on the surface thereof.
- It is abundantly clear that the calendered warp knit, weft inserted fabric has a face with a surface roughness of less than 2.0 microns which can readily be used as a banner fabric on which the face could be printed or in other applications such as a substrate for roofing fabric where adhesion and thickness is a factor or in a tenting fabric where smoothness thereof makes it more readily cleanable. As indicated the use of the warp knit, weft inserted fabric for the production of banner material is the preferred use thereof but other suitable uses may be made thereof where a low surface roughness below 2.0 microns is necessary to provide a viable product.
- The above described embodiment is given for the purpose of illustration only and it is understood that improvements and modifications may be made without departing from the scope of the invention as defined in the claims set forth below.
