Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a continuous reduction cleaning process for fabrics. Background Art

[0002] As we all know, due to the unique molecular structure of polyester, the bonding between disperse dyes and polyester molecules relies on van der Waals forces rather than chemical bonds. This also leads to the fact that after the disperse dyes are dyed on polyester, the dye macromolecules are easily separated from the polyester molecules. Therefore, reduction cleaning is required to remove the dye molecules that are not bound to the surface of the polyester molecules and improve their color fastness.

[0003] At present, the common reduction cleaning method for polyester fabrics is: receiving fabrics → desizing → dyeing → reduction cleaning → shaping. Specifically, after the fabric is off the loom, it is desized, dyed after desizing, cooled and washed after dyeing, and then reduced and washed after cooling to wash away the floating color on the surface of the fabric, and then high-temperature heat setting is performed. During reduction cleaning, add 1.5% (owf) of liquid alkali and 1.0% (owf) of insurance powder into the cylinder, heat it to 80℃ -90℃ and keep it warm for 20-30 minutes for alkaline reduction cleaning, and then cool it down to room temperature before taking it out of the cylinder to remove the dye molecules that remain on the surface of the polyester molecules and improve color fastness.

[0004] However, since the reduction washing of fabrics requires the addition of chemicals such as liquid alkali and hydrosulfite, if the concentration of chemicals cannot be replenished in time during the continuous reduction washing process, it will cause quality problems in the reduction washing.

[0037] The present invention will be further described below in conjunction with the accompanying drawings:

[0038] As shown in the figure, this embodiment provides a continuous reduction cleaning process for fabrics, comprising the following steps:

[0039] S1: reduction cleaning, the collected unwashed fabric is sent to the reduction cleaning machine, the reduction cleaning machine performs vibration cleaning and dynamic feeding on the fabric, ensuring full contact between the fabric and the chemical solution, ensuring the concentration of the reduction chemical, and ensuring the quality of reduction cleaning, the dyed fabric is cleaned by the cleaning equipment, the cleaning water inside contains 1.8g / L, 2.0g / L or 2.2g / L of reduction cleaning agent, the pH value of the cleaning water is 4, 4.2 or 4.5, and the cleaning water temperature is 90°C, 92°C or 95°C;

[0041] S4: drying and shaping, the washed textiles in S4 are quickly placed in a drying room for drying and shaping;

[0042] The reduction cleaning machine includes a water washing tank 11, a guide wheel group 12, a power wheel group, an oscillating cleaning rack 14, two feeding devices 15 and a storage box 16. The storage box 16 is used to store liquid reduction drugs. The guide wheel group 12, the power wheel group, the oscillating cleaning rack 14, the two feeding devices 15 and the storage box 16 are all installed on the water washing tank 11. The spinning material is sequentially wound around the guide wheel group 12 and the power wheel group. The spinning material passes through the oscillating cleaning rack 14. Each feeding device 15 is respectively installed on the oscillating cleaning rack 14. The upper and lower sides are connected to the power wheel group of each feeding device 15, the feeding device 15 is connected to the power wheel group, the feeding device 15 is connected to the storage box 16, the feeding time of the two feeding devices 15 is staggered, and the spinning material passes through between the two feeding devices 15, so that the upper feeding device 15 and the lower feeding device 15 alternately spray the chemical liquid on the passing spinning material, which can not only replenish the chemical liquid in real time, but also blow the chemical liquid to the spinning material from the upper and lower sides of the spinning material, ensuring the contact between the spinning material and the chemical liquid.

[0043] The guide wheel group 12 includes a plurality of guide wheels 121, each of which is rotatably mounted on the washing tank 11 and each of which is disposed at both ends of the power wheel group. The spinning material enters the power wheel group under the guidance of the guide wheel 121 on one side of the power wheel group, and the spinning material flows out under the guidance of the guide wheel 121 on the other side of the power wheel group. Each guide wheel 121 is used to guide the spinning material.

[0044] The power wheel group includes a first driving wheel 131 and a second driving wheel 132. The first driving wheel 131 and the second driving wheel 132 are rotatably installed on the washing tank 11. The first driving wheel 131 is provided with a first cam 1311, and the second driving wheel 132 is provided with a second cam 1321. The two feeding devices 15 are respectively connected to the first cam 1311 and the second cam 1321. The first cam 1311 and the second cam 1321 respectively provide power to the cloth of the corresponding feeding device 15.

[0045] Specifically, the principle of the first cam 1311 and the second cam 1321 providing power to the corresponding feeding device 15 is that: the plane where the axis of the first cam 1311 and the axis of the first driving wheel 131 are located is defined as a first pointing plane, the plane where the axis of the second cam 1321 and the axis of the second driving wheel 132 are located is defined as a second pointing plane, the first pointing plane and the second pointing plane are symmetrical with respect to the central axis of the oscillating cleaning rack 14, and the distance between the axis of the first cam 1311 and the axis of the first driving wheel 131 and the axis of the second cam 1321 and the axis of the second driving wheel 132 are symmetrical. The distances between the axes 32 are equal, and the axes of the first cam 1311 and the second cam 1321 are respectively located on the upper and lower sides of the plane where the axes of the first driving wheel 131 and the second driving wheel 132 are located, so that the push of the first cam 1311 and the second cam 1321 on the feeding device 15 can be staggered, and the feeding time of each feeding device 15 is different, so that each feeding device 15 can spray the liquid medicine toward the spinning material at different times, which means that the spinning material is pushed up and down by the liquid medicine and is in full contact with the liquid medicine in the washing tank 11, thereby ensuring the contact between the liquid medicine and the spinning material.

[0046] The oscillating cleaning rack 14 includes a cleaning frame 141 and a plurality of supporting legs 142, each supporting leg 142 is fixed on the cleaning frame 141, each supporting leg 142 is installed on the washing tank 11, and a feeding device 15 is installed on the supporting legs 142, each feeding device 15 is connected to the driving wheel transmission, each feeding device 15 is provided with a water outlet 153 on the cleaning frame 141, and the cleaning frame 141 is used to support each feeding device 15.

[0047] The feeding device 15 includes a movable piston 151, a feeding cylinder 152, a water outlet 153, a first one-way valve 154 and a second one-way valve 155. The movable piston 151 slides along the feeding cylinder 152. The first cam 1311 and the second cam 1321 respectively squeeze the movable piston 151 when they rotate. The first one-way valve 154 and the second one-way valve 155 are both installed on the feeding cylinder 152. The first one-way valve 154 is connected to the material storage box 16, and the second one-way valve 155 is connected to the water outlet 153. The movable piston 151 is respectively connected to the first driving wheel 131 and the second driving wheel 132. When the first cam 1311 and the second cam 1321 reciprocate to push the movable piston 151, The first one-way valve 154 and the second one-way valve 155 allow the liquid medicine in the storage box 16 to enter the washing tank 11. It is worth noting that the rotation speed of the first cam 1311 and the second cam 1321 is related to the spinning material. The faster the spinning material conveying speed, the faster the liquid medicine in the storage box 16 enters the washing tank 11, which further ensures the washing effect. The first one-way valve 154 and the second one-way valve 155 allow the reaction liquid in the storage box 16 to flow unidirectionally to the water outlet 153, and each water outlet 153 points to the direction of spinning material movement. In this way, the liquid medicine and the spinning material move in the same direction, and the spinning material and the liquid medicine flow in the same direction, so that the high-concentration liquid medicine is in contact with the spinning material for a longer time, which is more conducive to the quality of restoration washing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
