preparation example Construction

[0017] The preparation method of the above-mentioned segmental-shaped artificial leather comprises the following steps: (a) preparing segmented segmental composite fibers through two-component spinning equipment; (b) combing the segmented segmental segmental composite fibers after mixing them with low-melting-point fibers Laying the net, and then forming a composite non-woven fabric through needle punching machine coagulation processing; the low-melting point fiber is polyester, copolyester, polypropylene, nylon or polyethylene, and its mass content in the composite non-woven fabric is 0.1~ 1%, the melting point is 120°C-230°C; (c) padding, sanding, dyeing and finishing the composite non-woven fabric with polymer elastomer. The preparation process of the composite non-woven fabric is as follows: mix the segmental-shaped fiber and the low-melting-point fiber on the spunbond equipment, lay the net, enter the spunlace zone after pre-humidification, and open the fiber under the pre...

Embodiment 1

[0020] The present embodiment provides a kind of artificial leather of segmental pie type, it comprises polymer elastomer matrix, is arranged in the microfiber of polymer elastomer matrix, is formed on the surface of polymer elastomer matrix and is made of fine fiber fluff layer And the block fusion point that is formed in the fluff layer; the ultra-fine fiber is a segmented composite fiber, and the block fusion point is formed by a low melting point fiber (polyester); the preparation method of the segmented segmental artificial leather includes the following step:

[0021] (a) The two polymers (PET and PA, with a mass ratio of 70:30) slices are introduced into the drying tower for pre-crystallization and drying treatment, extruded and melted by the screw extruder, and then enter the spinning box after passing through the filter body; then use 16 segmented segmented spinning components, after air cooling into filaments, stretch to form segmental segmental composite fibers (for...

Embodiment 2

[0025] This embodiment provides a kind of artificial leather of segmental orange type, which is basically the same as that in Embodiment 1, except that the mass ratio of PET and PA is 60:40, and the core-sheath composite polyester fiber is selected as the low-melting fiber, and the sheath The melting point of the ingredients is 180°C; the segmented orange composite fiber (the fineness of the segmental segmented fiber is 0.05D) is mixed with the low melting point fiber at a weight ratio of 99.5:0.5, and then combed and laid to form a thin layer of reticular fibers. The fiber layer is entangled by the machine to form a non-woven fabric, and the grammage of the non-woven fabric is 150g / m 2 .

Abstract

The invention relates to an orange segment type artificial leather and a preparation method thereof. The orange segment type artificial leather comprises a macromolecular elastomer matrix, super finefiber set in the macromolecular elastomer matrix, a fluff layer that is formed on the surface of the macromolecular elastomer matrix and is composed of the super fine fiber, and blocky melt deposit points formed in the fluff layer. The super fine fiber is orange segment type composite fiber, the blocky melt deposit points are formed by low-melting point fiber, and are polyester or copolyester. Theorange segment type artificial leather provided by the invention has the advantages of good wear resistance, stable size, good color fastness and excellent mechanical properties, and can be applied to shoe upper leather, automobile interior decoration materials, furniture leather and the like.

Description

technical field [0001] The invention relates to an artificial leather, in particular to an orange petal-shaped artificial leather and a preparation method thereof. Background technique [0002] At present, most of the microfiber artificial leathers produced at home and abroad are made of sea-island superfine fibers. After opening and laying processes to make non-woven fabrics, they are processed by padding polyurethane PU coatings, alkali treatment, sanding, and dyeing. , finishing and processing. The dissolving method is adopted in the fiber separation, that is, the two-component fibers form ultrafine fibers by dissolving the sea components. At present, the most commonly used method of this dissolution method is toluene reduction or alkali reduction process, which will generate a large amount of organic wastewater, which not only causes certain environmental pollution, but also increases production costs. [0003] Aiming at the pollution problem in the microfiber artifici...
