In the case of two or more rolls (drums), it indicates the rotation speed ratio between the first and last rolls. Also, it is not necessary to use a special stretching roll or the like, and when the heat-sealing process is performed by pressure bonding using a hot embossing roll, the speed ratio between the embossing roll and the next transport roll, or hot air from two suction drums is applied to the web. In the case of the air-through process, it can also be indicated by the speed ratio of rolls and drums used during the heat fusing process, such as the speed ratio of two drums.

困難である。When the dry heat shrinkage in the width direction (width direction) of the long-fiber nonwoven fabric is less than -10%, the drawing process in the longitudinal direction must be performed at a draft ratio of 10% or more by the above-mentioned production method. In addition, troubles such as breakage of the sheet during the stretching process are easily caused, which is not preferable from the viewpoint of productivity. Conversely, when the dry heat shrinkage ratio exceeds 0%, when the base fabric after tufting the pile yarn is used as the base fabric for tufted carpet and the resin backing is performed, the preheating process is performed.
Under the temperature of 0 to 130 ° C., 120 to 180 ° C. during drying and curing of the backing resin and curing, in addition to the structural shrinkage in the width direction linked to the heat shrinkage of the pile yarn, the base fabric itself is large. Heat shrinkage in the width direction is not preferable because a necessary dimension in the width direction cannot be secured, and a problem such as a reduction in product yield is caused, which significantly deteriorates carpet productivity. Further, for example, by increasing the number of pile yarns tufted in the width direction and securing dimensions in the width direction, it is possible to secure the product yield, but there is a disadvantage that the cost for the increased pile yarns is increased. In addition, it is possible to secure the necessary width dimension by reducing the temperature of the preheating step and the drying and curing of the backing resin, curing, and suppressing the width shrinkage of the base fabric. However, the tufted carpet obtained in this case has a shrinkage force remaining in the base cloth. It is difficult to solve even the problems related to.

を招く結果となってしまうため好ましくない。When such a long-fiber nonwoven fabric is applied to a tufted carpet base fabric, the range of the dry heat shrinkage in the width direction (width direction) of the nonwoven fabric measured according to JISL 1906 is -5 to 0%. It is important that When the range of the dry heat shrinkage in the width direction (width direction) is less than -5%, the draft ratio needs to be set relatively high in the stretching process in the longitudinal direction in the manufacturing process of the nonwoven fabric.
The dry heat shrinkage in the longitudinal direction of the obtained long-fiber nonwoven fabric (tufted carpet base fabric) tends to increase, and the shrinkage in the longitudinal direction in the tufted carpet manufacturing process, particularly in the backing process, tends to increase. This is not preferable because it results in a decrease in the product yield although it is lighter than the problem that the dimensions cannot be secured.

必要はない。In the method for producing a long-fiber nonwoven fabric according to the present invention, it is preferable that the stretching in the longitudinal direction of the sheet is performed under heating conditions. When the sheet is stretched after being cooled, not only the thermal adhesion between the filaments is easily broken, but also in some cases, the filaments are easily cut, and the strength of the nonwoven fabric tends to be hardly obtained. The heating conditions during the stretching treatment are, when a low melting point component or an adhesive is present in the nonwoven fabric as an adhesive component, at a temperature equal to or lower than its melting point or softening point, more preferably 30 to 100 ° C. from the melting point. Preferably, the temperature is low. Further, when the temperature at the time of the heat fusion treatment remains as residual heat in the sheet, it is not always necessary to heat at the time of the stretching treatment.

Examples of the method of rapidly cooling the sheet include a method of passing through some cooling rolls and a method of blowing cold air onto the sheet. After the sheet is subjected to a stretching treatment, the sheet is rapidly cooled, so that the form of the sheet is maintained in a stretched state.

ィラメントとの混繊ウエブであることが好ましい。As described above, the presence of the difference in melting point is very preferable in terms of the characteristics of the obtained tufted carpet base fabric. Due to this difference in melting point, the bonding between the continuous filaments is performed only by the thermal melting and solidification of the low melting point component, so that the bonding points between the filaments are appropriately scattered, and the nonwoven fabric has a moderately loose structure. Occasionally, the filament is hardly cut by the tuft needle, and the strength of the base fabric after the tuft is not reduced. For this reason, it is preferable that the long-fiber nonwoven fabric is a mixed fiber web of a filament composed of a high melting point component and a filament composed of a low melting point component.

Also, the low melting point component has a higher melting point than the high melting point component.
Any thermoplastic resin may be used as long as it has a low melting point, but isophthalic acid copolymerization and adipic acid copolymerization are preferred because of the adhesion to the high melting point component and the fact that it is preferably composed of a similar resin during recycling.

優れるものである。By using the long-fiber nonwoven fabric of the present invention as a base fabric for tufted carpet, it is possible to suppress shrinkage in the width direction due to heat particularly in a backing step in the production of tufted carpet. Since the film is stretched in the nonwoven fabric manufacturing stage with respect to the tension in the longitudinal direction, the width shrinkage is small and the dimensional stability is very excellent. In addition, such a tufted carpet base fabric has a tufted carpet having a tufted pile yarn and a backing resin layer, and in particular, a tile carpet cut into a tile shape has no curling and has a small occurrence of warpage at four corners. It is very excellent in quality.

た。Example 5 An ethylene-vinyl acetate copolymer resin emulsion as a resin adhesive and dimethylpolysiloxane as a smoothing agent were applied to the sheet before the smoothing agent described in Example 2 (draft ratio was 3%). The non-woven fabric was impregnated with the active ingredient at a concentration of 6% and 1%, respectively, and dried at a temperature of 150 ° C. For drying, after pre-drying with a net dryer, drying and curing were carried out at a draft ratio of 1% using a number of suction drums to prepare a tufted carpet base fabric having a basis weight of about 100 g / m 2. did. The dry heat shrinkage in the horizontal direction of the obtained base fabric is −
1.0%. A tile carpet was prepared in the same manner as in Example 2. Comparative Example 1 A tufted carpet base fabric and a tile carpet were prepared in the same manner as in Example 1 except that the longitudinal stretching was not performed (relaxed state).
