The inventor researches and discovers that in the process of preparing the fabric, fibers on the surface of the fabric are potentially damaged due to large mechanical external cutting, or the fibers are directly cut and broken to be adsorbed in the fabric, fluff on the surface of the sanded fabric can continuously fall off through friction and stretching in the process of washing or taking, so that the whole household environment is influenced, and respiratory diseases of people can be induced. However, if the external cutting force is small, the fabric can be fluffed and pilling in the using process, and the skin-friendly feeling of the fabric is seriously affected.
According to the sanding device, the damage to fibers on the fabric is reduced to the minimum by adopting smaller external tension, and the hard sanding rollers and the flexible brushing rollers are combined and evenly distributed on the circumference of the hub at intervals, so that the fine and smooth sanded fabric is obtained, the cloth cover style including the peach skin-like fabric is achieved, and meanwhile, the good fuzzing and pilling resistance and the extremely low hair falling rate of the fabric are ensured.
In the sanding process, under the action of the auxiliary rotating rollers, namely the sanding rollers and the brush rollers in a plurality of numbers, the contact surface of the fabric and the auxiliary rotating rollers is greatly enlarged to form a curved surface, so that the stress points are increased, the contact mode that the traditional sanding machine presses the fabric on the sanding rotating rollers by adopting a compression roller method is changed, the contact surface and the pressure of the fabric are distributed on each auxiliary rotating roller, and the depth of the surface of each roller embedded into the fabric is greatly reduced; the invention changes the contact mode of the fabric and the sanding roller, namely, the traditional mode changes a few large contact surfaces into a plurality of small contact surfaces, thereby avoiding the fabric from being continuously and repeatedly damaged in the same single point or width direction, and because the contact mode is changed, the grinding force received by the fabric is also reduced even under the same tension, the fiber is not abraded or even broken, thereby reducing the risk of hair falling caused by fiber damage of the fabric.
Meanwhile, the hard sanding rollers and the flexible sanding rollers are evenly distributed on the circumference of the hub at intervals, and the flexible sanding rollers apply small force to the fabric in the process of preparing the sanded fabricBrushing the short ends of the surface fibers, and then quickly grinding the exposed ends by using a hard sanding roller; because the hard hair grinding rollers and the flexible hair grinding rollers are arranged at intervals and are simultaneously assisted with high-mesh carborundum grinding materials, hairiness adhered to the surface of the fabric is brushed down after the fabric is brushed and ground for multiple times, and potential damage of the fabric is avoided; the traditional sanding equipment firstly uses a hairbrush to perform fluffing and then performs sanding, the number of the abrasive grains is low, and thus although short and dense hairiness can be obtained, the short and dense hairiness has large damage to the face material and large required tension. In order to reduce the possibility that the fallen fiber fluff is reversely adhered to the fabric under the action of electrostatic attraction, a dust removal device is additionally arranged in a cavity of the fluff grinding equipment, namely 4 dust removal pipes are respectively arranged along the length direction, the diameter of each dust removal pipe is 180-4000 mm, and the suction per hour of each dust removal pipe is 2000-4000m3The floating hair on the fabric is absorbed to the greatest extent, so that the risk of hair falling caused by the floating hair of the fabric is reduced.

The re-bleaching process comprises the following steps: after 5 grids of hot water washing is carried out on the desized semi-finished product fabric, the desized semi-finished product fabric enters a re-bleaching steam box to be stacked, and then after 5 grids of hot water washing, the re-bleaching semi-finished product fabric is obtained; the re-bleaching process is 3g/L of 100% hydrogen peroxide, the stacking time is 50min, the stacking temperature is 102-105 ℃, and the pH of the working solution is 10-11.
In the sanding process, the sanding speed is 15-40 m/min, the rotating speed of the hard carborundum sanding roller is 900 revolutions per minute, the rotating speed of the flexible brushing roller is 500 revolutions per minute, the cloth feeding tension is 1.1kg, and the cloth discharging tension is 1.4 kg.
The fabric with the specification is not mercerized, and other processes such as dyeing, softening and preshrinking are conventional processes.
The performance indexes of examples 1 to 4 are shown in Table 1.
Table 1, examples 1 to 4, the performance indexes of the fabrics and the indexes of the fabrics are compared
The anti-pilling test method of the fabric adopts a Martindale method of a GBT 4802.2-2008 textile fabric pilling test. The fabric unhairing rate test method adopts a FZT 62027-. And (3) evaluating the hair falling of the fabric chassis, testing by adopting a GBT 4802.2-2008 textile fabric pilling test Martindale method, and observing the hair falling condition around the lower chassis of the operating platform. The fabric strength test method adopts the measurement (strip method) of the 1 st part breaking strength and the breaking elongation of the tensile property of the GBT 3923.1-2013 textile fabric. The fluff effect evaluation of the fabric adopts subjective evaluation of multiple persons and visual observation. The color difference rating of the fabric is evaluated by GB 250-2008.
From the examples 1 to 4, it can be seen that the cloth style effect is good, the touch is fine, the peach skin effect is good, and no obvious hairiness exists. Particularly, as the yarn count of the fabric is increased, the peach skin effect of the cloth surface is better and better, the pilling resistance grade of the fabric is obviously improved, the depilation rate of the fabric is reduced (the lower the numerical value is, the less the hair is fallen), and the depilation grade of the chassis is higher (the higher the grade is, the less the hair is fallen, the lowest grade is 1, the highest grade is 5, and the grade is 0.5/grade); under the same yarn count, specification and process conditions, after the material of the warp-wise yarns is changed from cotton to tencel, the peach skin effect of the cloth cover is better and better due to the effect brought by the fiber material. From the strength data, along with the increase of the number of the fabric, the strength of the yarn per se can be reduced, and finally the strength after sanding is reduced, but the other key indexes of the fabric cannot be adversely affected.

Comparative example 6
Based on the embodiment 2, the difference from the embodiment 2 is that the dust removing device is positioned in the cavity of the sanding device, the dust removing air suction device is arranged at the bottom of the box body according to the traditional sanding device, and the air suction amount per hour is 12000m3And the rest is unchanged.
Comparative example 7
Based on the example 2, the difference of the example 2 is that the cloth feeding tension is 2.0-2.4kg, the cloth discharging tension is 2.4-2.8kg, and the rest is unchanged.
TABLE 2 respective indices of comparative examples
It can be seen from comparative example 1 that, when only hard carborundum is used for sanding, although the fabric has dense touch and no obvious hairiness, and the fabric also has good anti-pilling performance, the fabric has poor unhairing rate, more chassis hair falls and serious strength damage. Compared with the prior art, the finishing method has the advantages that the finishing result is similar to that of the prior art in that the finishing method adopts conventional carborundum, and the fabric is seriously damaged due to the lack of buffering and carding processes.
It can be seen from comparative example 2 that, when only the flexible brush roller is adopted, the fluff falling rate and the strength damage of the fabric are low, but the anti-pilling performance of the fabric is poor, the fabric has general touch, the peach skin effect is avoided, the fabric surface hairiness is long, and the peach skin fabric preparation effect cannot be achieved.
As can be seen from comparative example 3, when the number of the hard sanding roller and the number of the flexible brush rollers of each auxiliary rotating roller were decreased, the contact surface of the fabric was increased, and the force applied to the fabric by the auxiliary rotating rollers was too large. Although the cloth cover has dense touch and short hairiness, the peach skin effect is not achieved, the unhairing rate is high, the chassis hair loss is high, and the fabric strength loss is serious. If the number of the auxiliary rotating rollers is continuously reduced, the fabric depilation rate is higher, and the strength loss is more serious.
It can be seen from comparative example 4 that when the number of the hard sanding rollers and the number of the flexible brushing rollers of each auxiliary rotating roller are increased, the sanding effect of the fabric becomes poor, the touch feeling is loose, the effect of no peach skin is not obvious, the surface hairiness is long, the anti-pilling effect of the fabric also becomes poor, and although the fabric depilation rate is better at this time. This is because the number of the auxiliary rotating rollers is too large, which causes the contact surface of the fabric to be greatly reduced, and weakens the acting force of the rollers.
It can be seen from example 5 that the hard sanding rollers and the flexible brush rollers of the auxiliary rotating rollers are randomly arranged on the circumference of the hub type main rotating wheel, the surface touch of the fabric is sparse, no peach skin effect is generated, the cloth surface hairiness is long, the indexes of the fabric such as anti-pilling effect and unhairing rate are general, because the randomness of the arrangement of the rollers is large, and the cloth surface hairiness cannot be combed and passivated.
From example 6, it can be seen that although the dehairing rate of the fabric and the chassis dehairing passed, there was a certain difference from the results of example 2. This is because even under the condition of the same amount of air suction, the single air suction easily causes the local suction too big, and the fabric running speed is faster and the effect of fine hair electrostatic attraction, causes the easy drop of float hair or the float hair is again sticky.
As can be seen from comparative example 7, the fuzz and pilling resistance of the fabric is obviously improved after the fabric feeding tension or the fabric discharging tension is increased, but great damage is caused to the fabric strength. This is because the friction between the fabric and the apparatus becomes large due to the increase of the tension, and the damage to the fiber becomes large.
The sanding equipment provided by the invention has the advantages that the damage to the fabric is extremely small in the sanding process, and the damage to the fiber strength caused by sanding can be avoided. The invention provides the method for preparing the sanded fabric by utilizing the sanding equipment, which adopts smaller external tension to minimize the damage of fibers on the fabric, and combines the hard sanding roller and the flexible brushing roller which are evenly distributed on the circumference of the hub at intervals, thereby obtaining the sanded fabric with delicate peach skin style, and simultaneously ensuring the good anti-pilling performance and extremely low hair loss rate of the fabric.
