Title (EN) PERFORATED NON-WOVEN FABRIC AND PRODUCTION METHOD THEREFOR
(FR) NON TISSÉ COMPRENANT DES TROUS DE PERFORATION ET PROCÉDÉ POUR LE PRODUIRE
(ZH) 一种打孔无纺布及其生产方法
Abstract:
(EN) Provided are a perforated non-woven fabric (1) and a production method for same. The perforated non-woven fabric is formed by overlapping three-dimensional conical perforations (C, D) of two layers of non-woven fabrics having perforations (11, 12). The first layer of perforated non-woven fabric (11) has a raised portion (B) and a recessed portion (A). The raised portion (B) comprises an inner space (E). An upper side of the second layer of perforated non-woven fabric (12) is adhered to a lower side of the recessed portion (A) of the first layer of perforated non-woven fabric (11). The overlapping three-dimensional conical perforations (C, D) pass through the first layer of perforated non-woven fabric (11) and the second layer of perforated non-woven fabric (12). An air flow passage is formed between the continuous internal spaces of the raised portions (B) of the first layer of perforated non-woven fabric (11) and the second layer of perforated non-woven fabric (12) and serves as a permeation passage for the non-woven fabric, thereby facilitating permeation of liquids and soft feces, reducing residue, favoring internal and external air circulation, and reducing discomfort from wetness. During processing, a needlepoint perforation process is utilized to tightly attach the first layer of perforated non-woven fabric to a convex roller (N), thereby effectively preventing dislocation of the two layers of non-woven fabrics during the joining process, simplifying the process, and reducing manufacturing costs.
(FR) L'invention concerne un non tissé comprenant des trous de perforation (1) et un procédé pour le produire. Le non tissé comprenant des trous de perforation est formé par chevauchement d'ouvertures en forme d'entonnoir tridimensionnelles (C, D) de deux couches de non tissé comprenant des ouvertures (11, 12). La première couche de non tissé comprenant des ouvertures (11) comporte une partie saillante (B) et une partie en creux (A). La partie saillante (B) comprend un espace interne (E). Un côté supérieur de la seconde couche de non tissé comprenant des ouvertures (12) est collé à un côté inférieur de la partie en creux (A) de la première couche de non tissé comprenant des ouvertures (11). Les ouvertures en forme d'entonnoir tridimensionnelles se chevauchant (C, D) traversent la première couche de non tissé comprenant des ouvertures (11) et la seconde couche de non tissé comprenant des ouvertures (12). Un passage d'écoulement d'air est formé entre des espaces internes continus des parties saillantes (B) de la première couche de non tissé comprenant des ouvertures (11) et la seconde couche de non tissé comprenant des ouvertures (12) et sert de passage de pénétration pour le non tissé, facilitant ainsi la pénétration de fèces liquides et molles, réduisant les résidus, permettant une circulation de flux d'air interne et externe, et réduisant la gène due à l'humidité. Dans un procédé de traitement, un procédé de perforation utilisant une tête d'épingle est appliquer pour fixer étroitement la première couche de non tissé comprenant des ouvertures à un rouleau saillant (N), ce qui empêche efficacement la dislocation des deux couches de non tissé pendant une opération de jonction, simplifie le procédé et réduit les coûts de fabrication.
(ZH) 一种打孔无纺布(1)及其生产方法,由二层开孔无纺布(11、12)的立体漏斗形开孔(C、D)套孔重叠复合而成;所述第一层开孔无纺布(11)具凸起部分(B)与凹入部分(A),所述的凸起部分(B)具有内部空间(E);所述第二层开孔无纺布(12)的上侧与第一层开孔无纺布(11)的凹入部分(A)的下侧进行粘结;所述套孔重叠的立体漏斗形开孔(C、D)贯穿第一层开孔无纺布(11)和第二层开孔无纺布(12)。第一层开孔无纺布(11)凸起部分(B)的内部连续空间与第二层开孔无纺布(12)之间形成有气流通道,为无纺布的渗透提供一个渗透通道,进而加快液体,排泄物软便渗透和减少残留,提供气流的内外循环,减少湿闷感。在加工中采用针尖的穿刺工序将第一层开孔无纺布(11)紧密的贴附在凸辊(N)上,有效防止复合加工过程中两层无纺布的错位,又简化了工艺,节省了制造成本。
