The present invention relates to a splittable multi-component fiber of good splittability, a method for producing it, and a fibrous article comprising it. More precisely, the invention relates to a splittable multi-component fiber of good splittability favorable for use in the field of industrial materials for battery separators, wipers, filters, etc., and also in the field of sanitary materials for napkin, etc. and relates to a method for producing it, and a fibrous article comprising it.

Splittable multi-component fiber, method for producing it, and fibrous article comprising it

The invention is directed to a split conjugated fiber.

Split type conjugate fiber, method for producing the same and fiber formed article using the same

A compact in-line high-speed apparatus and method for producing thermoplastic synthetic fibers includes a melt spinning device with a spinning block and a tow drawer; wherein the spinning block has at least one extruder, at least one spinneret block, and heating devices, and the tow drawer draws fibers spun from the spinning block as a bundled tow. Also provided is a drawn tow accumulating device equipped with at least two tow feeding rolls and a tow accumulating conveyer, wherein the tow feeding rolls feed the tow obtained from the tow drawer onto the tow accumulating conveyer, and the tow accumulating conveyer accumulates the tow fed from the tow feeding rolls. A high-speed tow stretching device is used for stretching tie tow supplied from the drawn tow accumulating device at high stretching speed.

The present invention provides a splittable composite fiber having improved processability on carding and superior splitting property by a splittable composite fiber comprising at least two thermoplastic resin components, and having a structure wherein a part of at least one of the components projects from the surface of the fiber.

Splittable composite fiber

A process for producing a non-woven fabric of ultrafine polyolefin fibers by subjecting a web of splittable conjugate polyolefin fibers to a water needle processing, and non-woven fabric thus obtained are described. The polyolefin composite fibers, contain 1.0 to 7.0% by weight of a hydrophilic component blended therein. The non-woven fabrics include ultrafine fibers having a size of 0.5 denier or less and a non-circular cross-section. Splitting and peeling off of the conjugate fibers and generation of static electricity with the composite fibers at a carding step is suppressed. The non-woven fabrics have an excellent wiping property, softness, and hydrophilic property.

Process for producing non-woven fabrics of ultrafine polyolefin fibers

Highly smooth fiber, fabric, and formed article

A high water-repellent fiber comprising a thermoplastic resin, wherein the following components (A) 75-90% by weight, (B) 5-20% by weight and (C) 1-5% by weight are adhered on the fiber 0.1-1.0% by weight per fiber:

High water-repellent fiber and nonwoven

Improvement in a hydrophilic function and in the strength of a cloth article obtained from a durable hydrophilic fibers is attained by the employment a durable hydrophilic fiber consisting of a fiber made of a thermoplastic resin to which 0.2 to 1.0% by weight of a mixture formed of the following surfactant (A),(B), (C), (D) and (E) is adhered:
