Embodiment 1

[0036] 1. The fineness of the multifilament is 82.5-333dtex (preferably below the fineness of direct-spun superfine fiber monofilament 0.95dtex), and the direct-spun superfine fiber colored before spinning is the pile warp (1), and the fineness is 82.5-222dtex high-strength fiber It is ground warp (2), ground latitude (3), and suede warp (1) adopts V font (as figure 2 or image 3 shown) or W font (such as Figure 4 Shown) consolidation, through the double-layer warp pile weaving technology, weaving double-layer fleece gray cloth on the pile loom (such as Figure 5 As shown), the velvet warp thread connecting the two layers of ground fabric is cut off by the cashmere cutting knife, so that the double-layer gray fabric is divided into two pieces with ground warp (2), ground weft (3) and V or W shape respectively. Cashmere warp (1), called wool surface, is a three-dimensional structure of single-layer cashmere gray cloth (such as Image 6 shown);

Embodiment 2

[0044] The direct-spun microfiber artificial leather obtained in Example 1 is detected, respectively from gram weight, thickness, TABER wear resistance, water immersion fading, normal temperature bending, burst strength, tensile strength, elongation, tear strength, friction Discoloration, peel strength, and wet type were tested, and the test results are as follows:

Embodiment 3

[0048] In the prior art, fiber opening must be carried out before dyeing, and the water, electricity and steam for fiber opening and dyeing have been counted. Taking a cloth with a thickness of 1.0MM as an example, the cost of dyeing is 800 meters per cylinder, and the required cost is as follows:

[0049] Water, electricity and steam required for fiber opening

[0050] Water: 48 tons Electricity: 220 degrees Steam: 2.1 tons

[0051] Water, electricity and steam required for dyeing

[0052] Water: 36 tons Electricity: 260 degrees Steam: 2.6 tons

Abstract

Disclosed in the present invention is a directly spun superfine fibre artificial leather and production method thereof, wherein a double layer warp pile weaving process is used; highly enhanced fibrils (or other filaments) are used as ground warps and ground wefts and directly spun Dacron superfine fibre or other superfine fibre as pile warps which are consolidated in a V shape or W shape; a 3D pile grey fabric is woven; then the product is obtained by padding with a polyurethane resin, a base treatment, buffing and finishing. The artificial leather of the present invention has a fine skin, a relatively high density, a strong leather texture, good wear resistance, stable size, hygroscopicity and air permeability, colour fastness and good mechanical performance, and at the same time also overcomes the defects of artificial leather used in the prior art, such as poor dyeing quality, a large amount of dye required, high energy consumption and environmental pollution; it can be used as leather for clothing and shoe leather uppers, as automotive interior material and as upholstery leather etc.

Description

technical field [0001] The invention relates to a superfine fiber artificial leather and its manufacturing method, more precisely, it is a kind of direct-spun superfine fiber as the main raw material, using a special three-dimensional weaving process, combined with a special polymer elastic body, using wet The suede leather obtained by the legal tanning process and the manufacturing method thereof belong to the field of textile and leather technology. Background technique [0002] At present, in the manufacturing process of microfiber artificial leather, it must be dyed to give the leather various colors to meet the needs of different users and purposes. However, due to the fine fiber, relatively large surface area and fast dyeing speed of ultra-fine fiber, it is easy to produce uneven dyeing; it is easy to color and fade quickly, resulting in poor color fastness; For different colors, the amount of dye required is relatively large. On the other hand, the dyeing of textile...
