Wherein:
color matching of color master batch: firstly, determining a color sample of a colored fabric, confirming a black master batch sample through a sample experiment according to a black sample provided by a customer, then imitating colored polyester fibers and colored viscose fibers in a sample machine, and confirming a color matching formula of the master batch. And putting the uniformly mixed coloring master batch and the PET slices into a spinning machine for melting or putting the uniformly mixed coloring master batch and viscose spinning solution into the spinning machine, extruding the solution into filaments through a spinneret plate to form coloring polyester fibers or viscose fibers, and spinning the coloring polyester fibers or viscose fibers into black master batch fabric.
Weaving of the fabric: blowing, cotton carding, drawing, primary pre-drawing, secondary merging, roving, spinning, automatic spooling, warping machine, slashing, reeding, air-jet weaving, cloth inspecting and rolling.
Blowing adopts a process of 'more loosening, more combing, less beating and low speed'; the cotton carding adopts a tighter carding distance and a slower speed to ensure the normal cotton carding process; the roving adopts a reasonable drafting process to ensure the evenness of the roving; the spinning step, actively unwinding by a spinning frame, and twisting by a roller drafting, a yarn guide hook, a steel collar and a steel wire ring to form yarn; when in spooling, the rotating speed of the spooling is properly reduced so as to reduce the broken end rate; the front, middle and rear rows have uniform tension during warping, the speed is reasonable, and the breakage rate of million kilometers is ensured; sizing and dampening reasonably for the purposes of reducing stretch, enhancing and improving wear resistance of yarns; weaving adopts small openings and high back beams to ensure full and clear cloth surface grains and improve weaving efficiency, and adopts methods of selecting yarns, designing a sizing process, technically improving equipment and the like to prevent staining phenomenon in the textile production process.
Enzyme rolling and short steaming: putting the color master batch interwoven fabric subjected to cloth turning and head sewing into a rolling desizing enzyme solution for multi-dipping two-rolling treatment, wherein the rolling enzyme is used as follows: wide temperature desizing enzyme: 6g/L and 10g/L of refining agent DM-1306; penetrant: 5 g/L; wherein the padding temperature is 80-85 ℃, the rolling residue rate is 100%, and then the padding is put into a human steaming box for carrying out compact short steaming, the steaming time is 5 minutes, and the steaming temperature is as follows: although the effect of stacking steaming in the steaming box is better at 100 ℃, stacking marks are easy to generate, and a compact short steaming method is adopted, so that the desizing effect can be achieved, and the stacking marks can be prevented.
After short steaming, hot water washing, soaping, water washing and drying, the whole enzyme rolling short steaming process is completed by the doffing and winding, and the wrinkling and printing can be effectively prevented by adopting the doffing and winding.
Singeing: in order to reduce the crystal points of the cloth surface as much as possible, the positive singeing is adopted. The singeing track number is reduced as much as possible, and the process adopts a positive singeing process, and the cropping and the rolling are carried out. For the singeing process, we performed the following tests on the fabric: no singeing, singeing one positive and negative, singeing two positive and negative. And (3) observing the crystal point condition of the singed cloth surface, and concluding that: the more the number of singeing tracks, the more the number of crystal points.
Brushing and hair absorbing process: the brushing and hair-sucking process adopts a hair brushing roller of a hair grinding machine to brush hair for 2 times, and then hair ash is sucked at a 3-time air suction port. Vehicle speed: 30m/min, and the rag is rolled. The cloth surface has more white spots with various shapes during production. The analysis reason is as follows: 1. the fabric is stained with the fluff during the spinning, 2, the white semi-product is basically produced during the pretreatment production, so the white fluff is easily stained on the colored cloth surface during the production of the master batch black cloth, and the solution is as follows: 1. the machine platform is made to be sanitary; 2. and a process of brushing and absorbing the flower hair is added after the pretreatment.
When a large sample is tested, a plurality of bright crystal points are seen on the black cloth surface after production is finished, the bright crystal points are more obvious in the sun, and the bright crystal points are attached to the cloth surface and can be removed by scraping the bright crystal points lightly with hands; the reason for the analysis is as follows: through a reverse inspection mode, crystal points exist on the grey cloth, and the crystal points are not easy to find only due to the fact that the grey cloth is sized and the hair feather of the cloth cover is more, and are the peeling phenomenon of viscose during spinning or the white flying of a workshop and a machine table; the solution is as follows: how to make the cloth cover crystal points fall off as much as possible in the production process is the key for solving the problem, and the test is carried out on each procedure.
The results were: 1. the mild desizing process can reduce the occurrence of crystal points; 2. the number of singeing tracks is reduced as much as possible; 3. the appearance of crystal points can be reduced by adding the brushing and hair absorbing processes.
Setting and tentering: the tentering and setting process comprises the following steps: padding, drying, shaping and cropping.
The normal process is to shape and then stretch, and in order to save cost, the process is refined and reduced, and the shaping and shaping are carried out at the same time.
