加热足以引起材料第二面(暴露的)34的收缩并使得材料第二面34上的纤维连接在一起或至少成为热稳定的。 A second heat-shrinkage sufficient to cause the material surface (exposed) 34 of the fiber 34 and such that the material on the second side are connected together, or at least become thermally stable. 更明确地,加热温度在材料熔点的5℃以内。 More specifically, the heating temperature in the material within the melting point 5 ℃. 当使用热风刀40时,材料以线速度约100~3000英尺/分从热风刀40下方通过,更普遍的是约500~2500英尺/分,希望达到约1000~2000英尺/分。 When using a hot air knife 40, the material at a line speed of about 100 to 3000 ft / min from the bottom 40 through the hot air knife, more generally from about 500 to 2500 ft / min, from about 1000 to 2000 the hope of achieving ft / min. 通常,从热风刀40出口的风速为约1,000~25,000英尺/分,优选约5,000~20,000英尺/分,更优选8,000~15,000英尺/分。 Typically, the knife 40 from the hot air outlet velocity is from about 1,000 to 25,000 ft / min, preferably from about 5,000 to 20,000 ft / min, more preferably from 8,000 to 15,000 ft / min. 材料在加热状态下拉伸并在拉伸状态下淬火,从而使材料收缩。 Tensile under heat and quenched in a stretched state, so that the material shrinks. 典型地,当暴露在热风刀的热量下时,材料趋于在横向上收缩。 Typically, when exposed to the heat of a hot air knife, the material tends to shrink in the transverse direction. 然而,材料可以在任何合适的方向上收缩。 However, the material can shrink in any appropriate direction. 在图3和图4中,横向由箭头48显示,纵向由箭头50显示。 In Figures 3 and 4, by arrows 48 show lateral, longitudinal by arrow 50 is displayed.

收缩量应为起始材料长度/或宽度的约10%~约40%,合适的是起始材料长度/或宽度的约15%~约35%,更合适的是起始材料长度/或宽度的约20%~约30%,当材料收缩时,材料第一面32上的纤维聚集,这样就形成了环28。 Amount of shrinkage as a starting material should be a length / or width of from about 10% to about 40%, the starting material is suitable length / or from about 15% to about 35% of the width, the starting material is more suitable length / width or from about 20% to about 30%, when the material shrinks, the first material on the surface of the fiber aggregate 32, thus forming a ring 28. 期望的是,无纺材料具有预存的内纤维连接花纹,如纺丝粘合网中的热连接花纹。 Desirably, the nonwoven material having a pattern stored within the fiber connection, such as a spun-bonded web in thermal connection pattern. 连接花纹42的合适实例为S-编织,如图5所示。 Suitable examples of the connection pattern 42 is S- weave, as shown in Fig. 另一个合适的内纤维连接花纹包括△连接。 Another suitable internal fiber connection patterns include △ connection. 具有预存的内纤维连接花纹的优点是更好地决定趋于在连接区域之间出现的环28的间隔和尺寸。 Advantage in the fiber connection with a pre-existing pattern is to better determine the connection area tends to occur between the spacing and size of the ring 28.

如图3和图4所示,当加热材料第二面34时,可以将材料放在有真空器46的成型丝网44上。 As shown in FIG. 3 and FIG. 4, when the heating material of the second surface 34, the material can be placed with a vacuum device 46 of the forming wire 44. 可控制真空器的,即,加大力度、减小力度或关闭,使得加热的材料在收缩方向运动。 Vacuum device can be controlled, that is, greater efforts to reduce the intensity or off, making the heated material movement in the direction of the contraction. 成型丝网44可通过在其表面形成凹槽、孔、锯齿等等花纹而变换,以使得加热材料第二面34时,只有与有花纹的成型丝网44接触的材料部分发生热收缩。 Forming wire 44 may be formed by a groove on its surface, holes, etc. sawtooth pattern is transformed, so that the heating of the material of the second surface 34, only a pattern of the forming wire 44 of the contact material portion are thermally shrunk. 使用有花纹的成型丝网44得到有花纹的环部件22。 Using a pattern of the forming wire 44 to obtain a pattern of the ring member 22.

连接花纹,如图5所示的S-编织连接花纹42,可在热连接工艺中应用到材料上。 Connection pattern, shown in Figure 5 in connection S- weave pattern 42, can be used in the process is thermally connected to the material. S-编织连接花纹42和其它合适的连接花纹描述于1999年10月12日公开的美国专利5,964,742中,在此引入作为参考。 S- braid connection pattern 42, and other suitable connection pattern described in U.S. Patent No. 5,964,742 on October 12, 1999 disclosed, herein incorporated by reference. 期望的是,纺丝粘合网的约10~25%与S-编织花纹连接。 Desirably, from about 10 to about 25% spunbonded web weave pattern with S- connection.

本发明的环部件22保持了材料第一面32上的原材料的柔软性。 The ring member 22 of the present invention maintains the flexibility of raw material 32 on the first face. 环部件22由至少一层材料制造,不经过任何机械拉伸并且除加热外,未使用粘接剂或其它任何类型的连接机构。 The ring member 22 is made of at least one layer material, without any addition to mechanical stretching and heating, not using an adhesive, or any other type of attachment mechanism. 因此,本发明的方法是制造功能环部件22的高效、高经济的方法。 Accordingly, the present invention is a method of manufacturing a ring member 22 of the functional efficiency, high economical method.
