熱処理することに関する。Description: TECHNICAL FIELD The present invention relates to a cylinder heat treatment of an orthogonal nonwoven fabric, and more particularly, to at least both ears of the nonwoven fabric between a circulation belt and a thermal cylinder so that the width direction of the web is reduced. It relates to heat treatment while limiting shrinkage.

のためエネルギ効率も悪い。またテンタ方式では直交積
層体では縦ウェブと緯ウェブの接着には不向きである。In recent years, a web that is strong in the vertical direction (abbreviated as vertical web)
Then, a cross-woven nonwoven fabric or cross-laminated film in which a web having strength in the weft direction (abbreviated as a weft web) is laminated and adhered has been developed and has come into the market. In these cross laminated bodies, it is necessary that the longitudinal web and the weft web do not become disjointed and that both webs are bonded and heat treated at the same time, and a thermal cylinder is generally used as a means for satisfying these conditions. Cylinder heat treatment is also characterized by a small space and high thermal efficiency. However, it was impossible to prevent the web from shrinking in the weft direction on the cylinder. Conventionally, cloth pin tenters and grip tenters have been used as a method for heat treatment while preventing the web from shrinking in the weft direction.However, these tenter methods not only require a very high equipment cost, but the equipment also requires a large space. Energy efficiency is poor because of the hot air system. Further, in the tenter system, the cross-layered structure is not suitable for bonding the longitudinal web and the weft web.
しかし、熱シリンダ上で熱処理すると収縮して幅が狭く
なり生産効率上マイナスであるばかりでなく、収縮によ
り強度、ヤング率が低下するので物性的にも悪影響があ
る。However, when heat-treated on a thermal cylinder, the width shrinks and the width narrows, which is not only a negative factor in production efficiency, but also the strength and Young's modulus decrease due to the shrinkage, which adversely affects the physical properties.

孔が開いていることが望ましい。As a result of intensive research conducted while comparatively examining various methods for the purpose of solving these problems, the following invention was reached as a cylinder heat treatment method having a large effect of reducing the shrinkage in the weft direction of the web at a low device cost. did. The longitudinal web and the weft web are laminated and guided onto the thermal cylinder, and at least both ear ends of both webs are gripped between the thermal cylinder and the belt circulating under tension to limit the shrinkage of the laminate in the weft direction. And reached a method of heat treatment. The place to be gripped may be only the both ends of the laminate, but may be the entire surface. When covering the entire surface, it is desirable that the belt has ventilation holes so that the evaporation of water can be smoothly performed.

１とヨコウェブ２はそれぞれ複数である場合もある。Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a vertical web 1, a horizontal web 2, and a circulation belt 3
Are stacked and guided to the heating cylinder 5 through the nip roll 4. Either one or both of the vertical web 1 and the horizontal web 2 must have adhesive ability or be adhesive-treated. Belt 3 is turn roll 6,
It circulates endlessly under tension through 6 ', 6 ". In some cases, the belt 3 may circulate to the press roll 7. On the heating cylinder 5, the vertical web 1 and the horizontal web 2 are laminated. , Both edges of the webs are gripped by the pressing force between the belt 3 and the cylinder 5, and are heat-treated while preventing the contraction in the horizontal direction, so that the vertical web 1 and the horizontal web 2 are bonded to each other. After the bonding is completed by the nip force, it is cooled by the cooling cylinder 8,
It is taken back through the nip roll 9. There may be a plurality of vertical webs 1 and multiple horizontal webs 2.

の第四は、非常に簡便な装置で、グリップテンタやピン
テンタと比較して装置コストが格段と安い。The first effect is that the width of the wide nonwoven fabric narrows when the shrinkage in the width direction is large on the heat treatment cylinder. According to the present invention, this shrinkage in the width direction can be reduced.
The second effect is that the horizontal web is taut and the product appearance,
In particular, the arrangement of the fibers of the horizontal web is neat and the appearance and strength are improved. Thirdly, since the shrinkage is limited, the tensile strength and Young's modulus of the product are improved. The fourth effect is a very simple device, which is much cheaper than a grip tenter or pin tenter.
