摘要:
Nonwoven web materials formed of a first outer accumulation, a second outer accumulation, and an inner accumulation of fibers are disclosed. The outer accumulations of fibers may form respective first and second macroscopic outer web surfaces. The webs may bear a pattern of thermal bonds impressed on either or both of the first and second macroscopic surfaces, at which the fibers of the first accumulation are thermally bonded to fibers of the second accumulation. Fibers of the inner accumulation may be interlaced among the fibers of the first and/or second accumulations and be present at the first and/or second macroscopic outer web surfaces. A related method for manufacturing nonwoven web materials is also disclosed.
摘要:
The present invention has an object to provide staple fibers suitable for manufacturing a wet-laid nonwoven fabric having excellent adhesive strength and heat resistance at a reduced environmental burden, a manufacturing method of the same, and a nonwoven fabric using the staple fibers. The object can be achieved by polyalkylene terephthalate or polyalkylene naphthalate staple fiber wet nonwoven fabric having excellent adhesive strength and heat resistance that are provided by blending and thermal-compression bonding of low oriented yarn and fully oriented yarn, wherein a specific ratio of biomass-derived carbon, fineness, fiber length, and a weight ratio between fully oriented staple fibers and low oriented staple fibers in the wet-laid nonwoven fabric are used to obtain a fine low oriented yarn having excellent binder performance and a fine fully oriented yarn having an unprecedented level of fineness.
摘要:
A material having a first surface and a second surface is disclosed. The first or second surface comprises a texture. The texture is defined by peaks and valleys such that the textured surface may have an Average Peak to Peak Distance in the range of about 3 mm to about 16 mm, an Average Height Differential of at least 1 mm, and a Surface Topography Index from about 0.1 to about 5. The material may comprise a surfactant.
摘要:
Nonwoven textile fabrics in accordance with the present invention are formed primarily of individualized bast fibers substantially free of pectin. The nonwoven fabric can include staple fibers to a lesser extent than the individualized bast fibers. Individualized bast fibers include fibers derived from the flax and hemp plants. The nonwoven textile fabric is formed into a web while in a dry state and subsequently bonded to produce a nonwoven fabric.

摘要:
A fusible interlining usable as a front fusible interlining in the textile industry includes a support layer including a weakly bonded and water jet-structured fiber web or nonwoven. The support layer is bonded in preselected areas by a binder and has an adhesive compound on at least one side. The support layer has a grid-like hole structure.
摘要:
A hydroentangled nonwoven material (8), includes a mixture of randomized continuous filaments (3) and natural fibers (5), wherein at least part of the staple fibers and/or the continuous filaments includes thermoplastic material. The nonwoven material is bonded in a non-random bonding pattern including a plurality of bonding sites (14) in which thermoplastic material included in the nonwoven material has been caused to at least partly soften or melt to create thermal bonds between the continuous filaments. The nonwoven material includes no other thermal bonds between the filaments than provided by the non-random bonding pattern. The nonwoven material may also contain synthetic staple fibers (6).
