Description

Fur-wool integrated fabric and preparation method thereof
Technical Field
The invention relates to the technical field of artificial leather, in particular to a fur-wool integrated fabric and a preparation method thereof.
Background
The artificial leather is a leather-like product which looks and feels like leather and can replace the leather. Generally, a fabric is used as a substrate and is coated with synthetic resin, and the fabric is mainly made of three types, namely PVC artificial leather, PU artificial leather and PU synthetic leather.
In order to increase the warmth retention property and the decoration property of the fabric, people invent fur integrated fabric.
The first is to make artificial leather or suede and then compound the artificial leather or suede and artificial fur into a fur integrated product by adopting a sponge flame compounding or glue compounding method. The second one is that the utility model patent "artificial fur" with patent application No. CN98208991.0 (publication No. CN2325206Y) discloses an artificial fur composed of three layers of different materials, namely, a pile fabric composed of a pile layer and a base fabric, and a leather layer attached to the pile fabric; the plush layer is woven on the base fabric, and then the PU resin is coated on the non-plush surface of the base fabric to form a leather layer.
The fur integrated finished product compounded by the first method has low elasticity, and no phenomena of compound foaming, delamination and the like exist in compounding. The fiber is easy to fall off from the side surface during cutting, and the hair falling phenomenon of the artificial wool is not improved much.
The second method mainly has the following problems: at present, the traditional wet-process PU bottom blank production line is a direct-coating method, the tension of base cloth on the production line is very high, and the difficulty of uniform coating on the back of elastic knitted fur is high. If the PU is produced by a dry PU line, the PU layer made by the dry PU line is thin and has no meat feeling.
The fur-wool integrated fabric manufactured by the two methods can directly see the weaving texture of the base fabric after a user pulls the fur layer, and the simulation feeling is weak.
Disclosure of Invention
The first technical problem to be solved by the invention is to provide a fur-integrated fabric which can be easily and uniformly coated, has a meat feeling, can not see base fabric weaving textures, has a stronger simulation feeling, is soft in hand feeling and is not easy to lose fur aiming at the current situation of the prior art.
The second technical problem to be solved by the invention is to provide a preparation method of the fur-integrated fabric.
The technical scheme adopted by the invention for solving the first technical problem is as follows: the fur and wool integrated fabric comprises fur and wool gray cloth, wherein the fur and wool gray cloth comprises base cloth and a fur layer woven on the front surface of the base cloth, and the fur layer comprises a plurality of furs woven on the front surface of the base cloth, and is characterized in that: the back surface of the base cloth is coated with an elastic polymer layer formed by a spraying process, and the elastic polymer layer penetrates into the gaps of the base cloth and overflows out of the front surface of the base cloth.
Preferably, the average thickness of the base cloth is recorded as D1, the average thickness of the elastic polymer layer overflowing from the front surface of the base cloth is recorded as D2, and the relation between D1 and D2 satisfies: D2/D1 is more than or equal to 0.5 and less than or equal to 1. The ratio of D2/D1 is too large, so that much slurry is consumed and the hand feeling is hard; if the ratio is too small, the polymer layer overflowing out of the front side of the plush base cloth is too thin, the textile weaving texture of the base cloth can be easily seen after the plush is poked, and the simulation feeling is not strong.
Further, the value of D1 is 180-500 μm, and the value of D2 is 90-500 μm.
Further, the average thickness of the pile layer is 5 to 60mm, and the average thickness of the elastic polymer layer is 450 to 1500 μm.
The technical scheme adopted by the invention for solving the second technical problem is as follows: the preparation method of the fur integrated fabric is characterized by comprising the following steps of:
(1) preparing plush gray cloth: producing plush gray cloth by using the superfine bottom yarns;
(2) spraying of the polymer material: and (2) aligning a spray gun to the back of the plush grey cloth prepared in the step (1) for spraying, so that the polymer material is uniformly sprayed on the back of the plush grey cloth, penetrates into the gap of the base cloth and overflows out of the front of the base cloth to form an elastic polymer layer, and the required fur integrated fabric is obtained.

A. cutting the sea-island type superfine fiber to an average length of 0.3-5 mm;
B. b, immersing the sea-island superfine fibers cut in the step A in alkali liquor, reacting for 30-60 min at 110-130 ℃, filtering, and drying to obtain superfine fiber flock filler;
C. and D, uniformly mixing the superfine fiber short velvet filler prepared in the step B with a resin matrix to obtain the required polymer material.
And further, in the step B, a fluff dyeing machine is adopted to react the sea-island superfine fibers with alkali liquor, the temperature is raised to the reaction temperature at the speed of 2-3 ℃/min before the reaction, the temperature is lowered to 70-90 ℃ at the speed of 2-3 ℃/min after the reaction, and then the filtration is carried out.
Further, the alkali liquor in the step B is NaOH solution, and the concentration of the NaOH solution is 5-12 g/L.
Further, the resin matrix in the step C is at least one of oil-based polyurethane, water-based polyurethane and polyvinyl chloride resin; the adding mass ratio of the resin matrix to the superfine fiber short velvet filler is 100: 8-25.
Further, in the step C, an ultrasonic wave nano stirring dispersion machine is adopted to uniformly mix the superfine fiber flock filler with the resin matrix, wherein the power of the ultrasonic wave nano stirring dispersion machine is 3000W, the working frequency is 20khz, and the cavitation intensity is 4.5W/cm2The rotating speed is 2000-3000 r/min, and the conveying flow rate is 1.5-2.5 t/h.

firstly, a spraying method is adopted to replace a direct coating method, so that the elastic knitted fur can be uniformly sprayed on the back of the elastic knitted fur through a modified wet-method polyurethane PU production line, a modified dry-method polyurethane PU production line, a modified polyvinyl chloride PVC production line and a modified plush sizing and setting machine;
secondly, the elastic polymer layer penetrates into the gaps of the base cloth and overflows to the front side of the base cloth, so that a user can not directly see the weaving texture of the base cloth after poking off the plush layer of the fur-wool integrated fabric, the plush is more like growing from the elastic polymer, and the simulation feeling is enhanced; in addition, the sea-island type superfine fiber cut to a proper length is treated by alkali liquor to obtain superfine fiber short velvet filler, and then the superfine fiber short velvet filler is added into a resin matrix to obtain a polymer material, and because the sea-island type superfine fiber is similar to collagen fiber in real leather, the prepared elastic polymer layer has high simulation degree, is soft and has a real leather feeling;
thirdly, the traditional sizing and shaping equipment for the bottom of the artificial wool aims at fixing the width and improving the hair falling, a roll coating device is arranged in front of the traditional shaping machine, the roll-coated sizing agents are attached to the surface of the back of the base cloth in actual operation, the fixing force of the fibers is weak, partial hair falling still exists, the deviation of the roll-coated sizing amount is large, random adjustment is difficult, and the base plate of the plush base cloth cannot meet ideal requirements during small-batch order production and is sometimes soft and sometimes hard; at present, a roller coating platform is changed into a spraying method, and slurry is sprayed into base cloth by utilizing spraying force, so that fibers at the root of fluff can be fully adhered, and the fluff falling is improved to the maximum extent.
