Problems solved by technology

[0002] Imitation cotton velvet is polyester superfine fiber. Polyester superfine fiber is a product with high quality, high performance, high technology content and high added value. Its monofilament linear density is much lower than that of conventional polyester fiber, which gives It is different from the excellent properties of conventional polyester fibers; in actual use, in order to obtain leather texture, enhance the strength of the imitation cotton velvet surface and achieve the effect of anti-wear, the imitation cotton velvet is used as the leather base cloth, and the leather and The leather-based cloth is compounded, and in order to play a decorative effect, both the leather and the leather-based cloth are colored layers, but the colored state of the leather and the leather-based cloth is generally achieved by dyeing. In actual use, the leather and the leather-based cloth Color migration will occur between cloths, and color migration will also occur between the leather base cloth and the adjacent cloth, which will cause the deviation of the surface color of the fabric and affect its surface quality

Embodiment 1

[0035] A kind of cotton-velveteen composite leather, with reference to figure 1 As shown, including the leather layer 2 and the leather base cloth arranged up and down, because after a period of use, color migration between the leather base cloth and the leather layer 2 is easy to occur, so the leather base cloth is made of polyester woven from colored fibers. Yarn warp-knitted leather base cloth body 1.

[0036] The leather base cloth body 1 is warp-knitted from polyester yarns. During the warp-knitting process, the polyester yarns include polyester filaments and polyester low-elasticity yarns, and the ratio of polyester filaments and polyester low-elasticity yarns is 3: 7.

[0037] Both polyester filament and polyester low elastic yarn are woven from colored fibers. The colored fiber is also divided into polyester filament colored fiber and polyester low elastic yarn colored fiber. Polyester filament colored fiber is made of appropriate amount of masterbatch and polyester f...

Embodiment 2

[0041] A production process of imitation cotton velvet composite leather, comprising the steps of:

[0042] Step A: Raw material selection, select an appropriate amount of purified terephthalic acid (PTA), dimethyl phthalate (DMT) and ethylene glycol (MEG) as raw materials for polyester filaments, and select an appropriate amount of polyester chips (PET) as Raw material of polyester low elastic yarn;

[0043] Step B: Add color masterbatch, add the desired color and appropriate amount of color masterbatch to the raw materials of polyester filament and polyester low elastic yarn, and mix the raw material and color masterbatch evenly by stirring, and dry the mixture at the same time ;

[0044] Step C: melt extrusion, feeding the mixed raw materials into a screw extruder to heat, melt and extrude;

[0045] Step D: Filtration, adding the melt-extruded intermediate to a melt filter for filtration, and distributing through a metering pump;

[0046] Step E: Spinning, filtering the me...

Abstract

The invention discloses a velveteen-like composite leather and it production technique. The velveteen-like composite leather comprises a composite leather base cloth and a leather layer; the leather base cloth comprises a leather base cloth main body formed by warp knitting spun polyester threads; the spun polyester threads are formed by weaving colored fibers; one side of the leather base cloth main body facing to the leather layer is provided with a fluffing layer. The production technique includes steps of step A, raw material selection; step B, color master batch adding; step C: fusion andextrusion; step D: filtering; step E: spinning; step F: spooling; step G: warping; step H: looming; step I: weaving; step J: post finishing; step K: compounding. The velveteen-like composite leatherand it production technique can avoid color migration in use and promote fabric surface quality and appearance.
