摘要： PROBLEM TO BE SOLVED: To provide a production method to obtain a heat adhesive property fiber in which a binding shape defect is small when being processed to a nonwoven cloth and a fiber structure.SOLUTION: A production method of a thermoplastic resin fiber is a method to produce a thermoplastic resin fiber in which at least a part of a fiber surface is composed of polyolefin by a melting spinning method, and is characterized in that during a discharge step of a thermoplastic resin from a nozzle to a taking-up step when performing melting spinning, to a fiber surface in an unstretched state, a polyether and polyester copolymer is adhered to a fiber weight in the unstretched state, then fiber in the unstretched state is drawn, and a hydrophilic oil solution is imparted to a fiber weight of the stretched yarn.

摘要： PROBLEM TO BE SOLVED: To provide a production method to obtain a heat adhesive property fiber in which when being processed to a nonwoven cloth or a fiber structure, a defect of a binding shape or a nep shape is few.SOLUTION: A production method of a thermoplastic resin fiber is characterized in that when a fiber including a thermoplastic resin in which a melting point of a fiber surface is at most 200°C is performed by melting spinning, a sulfonic acid metal salt is imparted by at least 0.005% per a fiber weight between a process in which the thermoplastic resin is discharged from a cap and a take-off process, thereby when spinning, a specific agent is imparted to a fiber surface, and thereby while agglutination of fibers to connect a product defect is prevented, the heat adhesive property fiber that can be stably produced can be produced.
摘要翻译：要解决的问题：为了提供一种获得热粘性特性纤维的制造方法，其中当被加工成无纺布或纤维结构时，结合形状或棉形形状的缺陷很少。解决方案：一种制备方法热塑性树脂纤维的特征在于，当通过熔融纺丝进行包含纤维表面的熔点在200℃以下的热塑性树脂的纤维时，磺酸金属盐的含量至少为0.005％将热塑性树脂从盖子排出的工序和脱脂工序之间的纤维重量，由此在纺丝时，赋予纤维表面特定的试剂，从而防止纤维的凝集，从而连接产品缺陷，可以制造可稳定生产的热粘性纤维。

摘要： PROBLEM TO BE SOLVED: To provide a simple method for producing a nonwoven fabric by an air-laid process by which a uniform web having good opening properties can be produced and energy and space can be saved without requiring a large-scale apparatus and to provide an apparatus for producing the same. SOLUTION: The method for producing the nonwoven fabric by the air-laid process comprises transporting a short fiber aggregate vertically downward with a transporting air stream, introducing the short fiber aggregate into an opening chamber (2) for housing the short fiber aggregate, making the air stream fed from a feed port (8) collide with an air stream fed from an introduction port (9) for outside air in the opening chamber (2), producing a turbulent flow forming a rising air stream and a lowering air stream, making the transported short fiber aggregate collide with a flat platy opening member (1) formed in the lower end of the opening chamber (2) and having a plurality of openings, further opening the short fiber aggregate, then depositing and collecting the opened short fiber aggregate in a flat surface shape on a depositing and collecting means (3) and affording the web. The apparatus for producing the nonwoven fabric is provided. COPYRIGHT: (C)2004,JPO
