Description
Technical Field
The invention relates to the field of fabrics, and in particular relates to a preparation method of denim fabric.
Background
The jeans wear is not weak in all over the world due to the rough, random and comfortable style, the jeans fabric is derived and developed continuously along with the development of the jeans wear, and can be divided into common cotton, polyester-cotton blended fabric, spandex interweaving, chenille and the like according to raw material components, and can be divided into single yarns, folded yarns, filament yarns and compound folded yarns according to different spinning. In order to achieve the purpose of warm keeping, the jean-like fabric adopting jeans made of all wool and capable of keeping warm appears in the market at present, and due to the fact that wool does not fade, the jean-like fabric cannot achieve the washing effect, is not attractive enough, and is high in price. Most common jean fabrics are mainly made of pure cotton interweaving, although the washing effect can be achieved, the wear resistance is poor, the jean fabrics are not warm, and the jean fabrics cannot keep the original chromaticity for a long time due to the fact that the cotton fibers are easy to fade after being dyed.

Further, the diameter of the short fibers is 14-16 mu m, the fiber length of the wool is 38-380 mm, and the diameter of the cotton threads is 12-15 mu m.
Further, the mass content of the wool is 3% -8% of the total mass of the manufactured jean fabric finished product. Further preferably, the weight of the denim fabric is 270-350 g/m2Preferably 150g/m2. The heat preservation effect of the obtained fabric finished product can be ensured, and the fabric finished product is not too bulky and heavy.
Further, the wool is subjected to wool washing treatment before twisting, and the wool washing treatment specifically comprises the following steps: adopting soap as a detergent and sodium carbonate as a builder, controlling the pH value to be 8-9, controlling the temperature to be 40-55 ℃, and controlling the wool washing time to be 10-20 min; the soap is 2-4% of the wool to be treated, and the sodium carbonate is 2% of the wool to be treated. The wool washing treatment is a soap-alkali method in an emulsification method, and under the condition of weak alkali, the soap-alkali method cannot damage wool fibers and can well remove color stains on the wool.
Further, the indigo dyeing process specifically comprises: according to the warp: weighing warp yarns and the indigo dye according to the mass ratio of (1.8-2.2), soaking the warp yarns in the indigo dye for dyeing, taking out the soaked warp yarns for air drying, and obtaining the dyed warp yarns after air drying.
Further, the indigo dye is an acid dye and is prepared by mixing natural indigo and the plastocyanin according to the weight ratio of 1 (0.65-0.85). Further preferably, the weight ratio of native indigo to plastocyanin is 1: 0.75.
Further, the soaking temperature is 35-45 ℃, the soaking time is 1.5-2.5 hours, the air drying temperature is 80-85 ℃, and the air drying time is 30-50 min. Further preferably, the soaking time is 2 hours and the air drying time is 40 min.
Furthermore, in the satin weaving process, the warp yarns and the weft yarns are vertically woven according to a one-upper-three-lower structure or are circularly woven according to left twill, and the woven fabric finished product has stronger concave-convex feeling.
Furthermore, the density of warp yarns of the finished fabric product is 100-125 yarns/inch, and the density of weft yarns is 60-75 yarns/inch. Further preferably, the warp density of the finished fabric is 111/inch, and the weft density is 68/inch.
Furthermore, residual color stains in the fabric and impurities in the fibers can be removed in the desizing process; the finishing process specifically comprises the following steps: putting the washed and dried fabric into a softening liquid for finishing, so that the waterproof, antistatic and hand feeling of the fabric are obviously improved after finishing; the fabric is subjected to scutching and drying in the shaping process and then is detected, so that the fabric can be shaped through a high-temperature shaping machine according to the requirements of a user after the fabric is ensured to have no problem.
The invention adopts the short fibers and the wool to twist to form the warp, and the short fibers have the dyeable characteristic, so the warp can be placed in the indigo dye and can be used as a denim layer after dyeing treatment, and the curled structure of the wool can lock the air, so the heat preservation effect of the wool is more than 2 times of the heat preservation performance of the same thick and thin fibers. The obtained jean fabric can be washed by water to realize the effect of washing the jean and can also meet the requirement of keeping warm of a user in autumn and winter in a crossed season.
