Abstract

The present invention uses the slope of the air entanglement between the eluted polyester composite yarn and the high shrink yarn as a warp yarn, and the polyester yarn containing inorganic fine particles as the weft yarn to refine, shrink, reduce the alkali, and dye the woven fabric. A method of producing deep color suede tissues by sanding, followed by padding-drying-curing with a thin layer-forming low refractive index resin.

Fabrics produced according to the present invention, since the low refractive index resin lowers the reflected light on the surface of the fabric to increase the apparent concentration of the dye dyes, even if the dye usage is increased, the dyeing fastness is not lowered and the deep color is exhibited.

Description

How to adjust suede fabric

The present invention relates to a method of expressing a suede tissue having a raised portion of ultrafine fibers on its surface in dark black, that is, deep color.

Microfibers have a lower apparent surface concentration than dyes, despite the same or higher dyeing rate than regular fibers. That is, in the case of ultrafine fibers, the apparent surface concentration is reduced, which is the same as the surface area of the fiber is significantly increased and the reflected light at the fiber surface is dispersed, so that the actual apparent surface concentration of the dye is thinned. For example, in order to obtain the same density as 3% denier fiber was stained with 1% o.w.f, the same density would not be obtained unless it was dyed with 1.7% o.w.f for 1 denier and about 3% o.w.f for 0.3 denier. However, increasing the amount of dye in order to dye the ultrafine fibers in deep color, as well as poor colorization, there was a problem that the washing, daylight, sublimation fastness.

The present invention is to prepare a high-density fabric by using an elution type polyester bishrink blended yarn as a warp yarn, a polyester yarn containing inorganic fine particles as a weft yarn, and then the surface is treated with a low refractive index resin having a thin layer coating performance It is an object of the present invention to provide a method of improving the apparent surface concentration of dyes in the microfiber portion expressed on the surface of a dyed fabric, and preventing various dyeing fastnesses from being degraded even at high concentrations.

Iii) After the air entangled with the high shrinkage polyester yarn, the slope is inclined, and a high-density fabric is produced by using a twisted yarn of polyester yarn containing inorganic fine particles as a weft yarn, and the fabric is refined and then reduced and alkalined. The present invention relates to a method of manufacturing a suede-feeling deep-colored fabric characterized in that it is treated with a low refractive index resin having a thin coating performance after dyeing and brushing.

燃)하고, 이것과 이용성 폴리에스테르 플리머를 용출시킨 후 극세섬유가 표면에 표출될 수 있도록 고수축 폴리에스테르 필라멘트사를 공기교락하여 용출형 이수축혼섬사를 제조한후 이것을 통상의 호부공정을 거쳐 경사로 사용하였다. 위사로는 무기미립자가 함유된 폴리에스테르 가연사를 좌연과 우연으로 각각 연사하고 동일 방향의 원사를 2합하여 2단 연사하여 통상의 세팅방법으로 세팅하여 위사로 사용하였다. 제조된 경, 위사를 사용하여 고밀도 직물로 제조하였다.In the present invention, it is preferable that the ratio of the general polyester polymer and the usable polyester polymer is 6: 4 to 8.5: 1.5 in weight ratio.

Iv), eluting this and the usable polyester polymer, and then air-interlacing the high shrink polyester filament yarn so that the microfibers can be exposed on the surface. Used as a ramp. As the weft yarn, polyester twisted yarns containing inorganic fine particles were twisted into left and right edges, respectively, and two yarns of two yarns in the same direction were twisted and set in a conventional setting method and used as weft yarns. The prepared warp was made of a high density fabric using a weft yarn.

In the present invention, it is preferable to use the eluted polyester composite yarn having 100 denier and the high shrink polyester yarn having 40 denier.

The high-density fabric of the ultrafine fibers is refined in a broad form to completely remove the mixed emulsion or foam. In order to express the bulkiness of the microwave in the micro shrink fabric, it is necessary to use a facility for relaxation. In other words, in the liquid dyeing machine, ionic refining agent and caustic soda are added to treat the multi-stage shrinking condition to maximize the shrinkage characteristics of the fiber.

Refined and reduced fabrics are pre-set and treated with alkaline solution for 25-30% alkali reduction. If the alkali loss ratio is less than 25% by weight, two colors may occur during dyeing due to undivided, as well as a cause of brushing unevenness during sanding, and when the weight loss exceeds 30% by weight, the elasticity of the fabric is considerably reduced with slip occurrence. As above, the weight-reduced fabric is dried and then sanded to create a brushed microfiber on the surface of the fabric.

The brushed fabric is dyed with black dispersion dye. The dyeing speed of disperse dyes for microfibers is considerably faster than that of ordinary fibers. In addition, the surface concentration actually seen when dyed with the same amount of dyeing is thinner on the microfiber side, so that the dye particle size distributed relatively to the finer fine fiber to dye the material mixed with fibers of different fineness to increase the color It is better to use large SF type dyes. What is necessary is just to perform the density | concentration of dye in 8 to 12% o.w.f, and dyeing time in the range of 30 to 90 minutes. After dyeing, drain the waste liquid, cold water washing, reducing washing, waste liquid draining, and cold water washing. Microfibers have a very high surface dyeing amount, so the reducing washing conditions must be strengthened. Reduction washing is performed at 75 to 80 ° C. for 20 to 40 minutes in a mixed bath of 2 g / l hydrosulfite and 2 g / l caustic soda.

Since microfibers have a larger surface area than ordinary fibers, the apparent surface concentration decreases even when the same amount of dye is used. Conventionally, the amount of dye is increased in order to color the microfibers and general fibers in the same way, but the dyeing amount of the microfiber fabrics is much higher than the dyes of the same color dyes, so the sublimation fastness, daylight fastness, The friction fastness etc. fell. Therefore, in the present invention, in order to sharpen and deepen the dyeing material of the ultrafine fiber fabric, the resin is treated with a low refractive index resin having a thin coating performance.

In this manner, the black fabric using the modern fiber improves the apparent density compared to the general fabric. The apparent density is improved because the reflected light on the fiber surface is lowered to form a deep color. The resin treatment used a pad-dry-cure method. The deep color suede fabric produced by the present invention has no change in drape and resilience, and has excellent clarity and color, and has a suede texture.
