A method for producing a fiber having a pattern on a surface thereof, the method including forming a resin composition layer having a linear first pattern using a resin composition; and forming a second pattern on the resin composition layer. The second pattern may be formed by forming a thin film of a block copolymer comprising at least two block chains different from each other in surface free energy on the resin composition layer and subjecting the block copolymer to microphase separation. Alternatively, the second pattern is formed by adhering particles onto the resin composition layer.

A method for producing a fiber having a pattern on a surface thereof. The fiber is produced by a method including forming a photosensitive composition layer on a template layer having a pattern, bonding a film including an adhesive layer on a principal plane onto the photosensitive composition layer, linearly exposing the photosensitive composition layer to light, separating an exposed laminate comprising the photosensitive composition layer, the adhesive layer, and the film from the template layer, and developing the photosensitive composition layer in the separated laminate.

A non-woven fabric board for an exterior of a vehicle and a method for manufacturing same are provided. The non-woven fabric board includes a matrix fiber having a non-circular cross-section and an adhesive fiber having a non-circular cross-section, and the matrix fiber is included in an amount of 50 wt % or greater based on the total weight of the non-woven fiber board. Each of the matrix fiber and the adhesive fiber have a linear density of about 6 to 15 denier and a degree of non-circular shape of about 1.3 to 3.0.

The non-woven fabric board for an exterior of a vehicle has a substantially increased specific surface area by using the non-circular cross-section fibers, improved adhesion efficiency between fibers, and substantially improved mechanical properties. In addition, heat moldability thereof is improved, weight thereof is reduced, and the sound-absorbing performance thereof is substantially improved.

Glossy fibers can be processed into woven or knitted fabric suitable for clothing applications while exhibiting a sense of deep, lustrous glossiness. The glossy fibers are characterized by having an average reflectance for the visible light region of 20% or greater, an average transmittance of 40% of less, and a contrastive glossiness of 3.0 or less.

The present invention relates to a method for producing a functional yarn, in which zirconium phosphate having a multiple-layered structure is used as a deodorizing material and a melted polymer is spun through a spinning nozzle having a multi-lobal sectional shape. According to the present invention, the melted polymer contains layered fine zirconium phosphate inorganic particles having low hardness, and thus the abrasion of production process equipment can be minimized during fiber production and also an excellent deodorizing property and an excellent sweat-absorbing and quick-drying property are exhibited.

The invention discloses environment-controlling fibers, method manufacturing the same and fabrics using the same, which adopts polyolefin material, optoelectronic material, thermoelectric material, piezoelectric material and catalyst material, to make fibers and fabric by melting, mixing, drawing and weaving.
