A spontaneously degradable fiber excellent in bulkiness, softness, stretchability and feeling, which comprises (A) a low heat-shrinkable fiber component comprising a high crystalline aliphatic polyester and (B) a high heat-shrinkable fiber component comprising an aliphatic polyester, e.g., a low crystalline or non-crystalline aliphatic polyester, and a block copolymer or a mixture the main component of which is an aliphatic polyester and which comprises a high-melting component and a low-melting component. Further, fibers excellent in self-crimpability or self-adhesion property and dividable fibers are obtained by suitably combining the fiber components (A) and (B) to form conjugated fibers or composite yarns.

Spontaneously degradable fibers and goods made thereof

Biodegradable copolyester, molded article produced therefrom and process

An artificial fur having chinchilla-like appearance and hand, which consists of a substrate fabric and piles provided on at least one surface thereof, which piles comprise underhairs of 0.5 to less than 4.0 deniers, having an average length of 10.about.35 mm, a hair density of 8,000.about.30,000 hairs/cm.sup.2, a crimp ratio of at most 20%, a frictional coefficient in the right direction of 1.6 or less and a frictional coefficient ratio of the adverse direction to the right direction of 1.0.about.1.4. The piles preferably further comprise guard hairs of 4.about.50 deniers, equal to or a little longer than underhairs, having a hair density of 3,000 hairs/cm.sup.2 or less. The piles preferably have color variations lengthwise.

Chinchilla-like artificial fur

A method of producing abrasive fibers is disclosed, which comprises providing a conjugate fiber comprising at least one abrasive layer containing abrasive particles and at least one coating layer substantially covering the abrasive layer, and removing at least a part of the coating layer from the conjugate fiber with a solvent or a decomposer to expose at least a part of the abrasive layer from the coating layer.

Method of producing abrasive fibers

An artificial fur-like pile article is a cloth-like fibrous structure provided with piles having a length of more than 10 mm, each pile composed of a non-attenuated portion where the fineness does not substantially vary in the length direction, an attenuated portion where the fineness is gradually reduced toward the top end and a fine top end,

Pile articles with attenuated upper portion and a method for producing

Fur-like article having pile with difference in color or fineness

Pile articles, such as artificial furs, wherein at least a part of piles is colored in at least two kinds of colorations which vary in the length direction of the piles, said color variation being caused on level surfaces distant substantially constantly from a substrate fabric of said pile articles over a broad area of said pile articles, are produced by rotating a fibrous structure having piles fixed on a rotating body to raise the piles owing to centrifugal force caused by the rotation and contacting the raised piles with a treating liquid for fibers retained in a rotary container wherein a cylindrical interface of the treating liquid is formed due to the centrifugal force. The pile articles wherein the piles are uniformly gradationally colored in the length direction of the piles are also produced by gradually moving the above described level surface.

Pile articles and a method for producing the pile articles

Conductive composite filaments are disclosed that are formed by conjugate-spinning a conductive component composed of a thermoplastic polymer and/or a solvent soluble polymer and conductive metal oxide particles and a non-conductive component composed of a fiber-forming polymer.

Conductive composite filaments and methods for producing said composite

An apparatus for producing pile articles having complicated and high color tone and structure, such as artificial furs, writing brushes, brushes, etc. comprises a rotating body to which a pile article is fixed and which is rotated together with the pile article whereby centrifugal force is applied to the piles, a rotary container wherein at least one treating liquid for the above described piles is retained and at least one inner interface of the treating liquid is formed owing to the centrifugal force caused by the rotation to contact the piles with the treating liquid, and a feeding portion from which the treating liquid is fed into the rotary container and a discharging portion from which the treating liquid is discharged.
