The cashmere textile is light in weight, surface fiber fluff has certain water repellency and is not easy to wet, the surface fiber fluff is easy to float on the water surface in the washing process, the cashmere textile can be wetted through soaking for a long time or spraying water with proper pressure, the cashmere sweater is guaranteed to be wetted through daily hand washing by adopting a pressing and soaking mode, the cashmere fiber is high in water absorption, the weight is heavy after the cashmere fiber is wetted through soaking, and the cashmere sweater is easy to pull and deform.
At present, the washing machines do not have special washing programs for washing cashmere fabrics, most washing machines are configured with wool or hand washing programs, but the cashmere fabrics and the wool fabrics have obviously different characteristics, the cashmere fabrics are mainly knitted by cashmere as a raw material, the scales on the surfaces of the cashmere fibers are small and smooth, and an air layer is arranged between the fibers, so the texture is obviously lighter than that of the wool fibers, the crimp number, the crimp rate and the crimp response rate of the cashmere fibers are all higher, the cashmere fibers are arranged closely in textile manufacturing, the cohesive force is good, and the heat retention is good; the cashmere fabric is specially provided with a fulling process in the processing, so that part of fibers in a mantle are dissociated and cover the surface of the cashmere fabric to form a layer of thin fluff, and the layer of fluff has certain water repellency, so that the wetting time of the cashmere fibers is obviously longer than that of the wool fibers, the moisture absorption capacity of the cashmere is strongest in all the fibers, the moisture regain is about 15 percent and is 3 times of that of the wool fibers, and therefore, the eccentricity formed by the cashmere fabric is larger during dewatering. When the existing wool or hand washing program is used for washing cashmere fabrics, the cashmere fabrics cannot be completely soaked in the water inlet process, are difficult to wet thoroughly when floating on the water surface all the time in the washing process, cannot be dewatered due to overlarge eccentricity during final dewatering, are continuously and uniformly distributed by a washing machine for a long time, and the like, so that the cashmere fabrics cannot meet the requirements of high cleaning, low abrasion, no fluffing and pilling on the surface and the like in the whole program operation.
Therefore, the cashmere textile has light weight, the surface fiber fluff has certain water repellency and is not easy to be soaked, and the cashmere textile is easy to float on the water surface in the washing process and can be soaked for a long time to be thoroughly soaked; when the impeller full-automatic washing machine is used for washing, cashmere fabrics can not be completely soaked on the floating water surface in the washing stage, so that the cleaning and uniformity are affected; in the rinsing stage, the soaked cashmere fabric is suspended in water, the thoroughly soaked cashmere fabric is pulled into the water by the stirring water flow of the impeller and overturns, the surfaces of the cashmere fabrics rub against each other to generate serious fuzzing and pilling, and the edges of the sleeves, the lappets, the scarf and the like are easy to stretch, deform and wear, so that the heat retention and the external hand feeling of the cashmere fabric are influenced.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1-6, an embodiment of the method for washing cashmere fabric according to the present invention is a method for washing cashmere fabric, which uses a full-automatic washing machine to wash cashmere fabric, where the full-automatic washing machine includes an outer tub 1, an inner tub 2, a pulsator 3 disposed at the bottom of the inner tub, a water inlet valve, a water inlet 4 communicated with the water inlet valve, and a water discharge valve 5, where the washing machine is provided with a "cashmere fabric" program, and the detergent is a silk wool detergent for cashmere fibers; and for washing a cashmere fabric 6 each time, namely washing one cashmere fabric, not suitable for washing more than once, preferably using a washing net bag to more effectively reduce abrasion and surface fuzzing, wherein the temperature of washing water is 20-25 ℃.
In the embodiment, referring to fig. 1, the method for washing the cashmere fabric 6 specifically includes the following steps:
A. in the water inlet stage, firstly, a penetrating water inlet step is operated, as shown in fig. 2, the inner barrel 2 and the impeller 3 are driven to synchronously rotate in the same direction at a first penetrating water inlet rotating speed, the water inlet valve is opened, the cashmere fabric 6 synchronously rotates along with the inner barrel 2 and the impeller 3 under the action of rotating centrifugal force, and the inlet water flow sprayed on the cashmere fabric can penetrate the cashmere fabric to enter the outer barrel, so that the fluff of the cashmere fabric 6 is gradually soaked; entering a synchronous water inlet step after the water level in the outer barrel 1 reaches a first set water level a; the inner barrel 2 and the impeller 3 are driven to synchronously rotate at low speed at intervals, and the cashmere fabric is suspended in water and moves along with the water flow to gradually soak the cashmere fabric 6; and when the water level in the outer barrel reaches the second set water level b, closing the water inlet valve, and ending the water inlet stage.
In the stage, after the washing machine is started, the water inlet valve is controlled to be opened, the inner barrel 2 and the impeller 3 are driven to synchronously rotate in the same direction at the set first penetrating water inlet rotating speed, the speed is increased to the set first penetrating water inlet rotating speed in a short time, and the relative motion between the cashmere fabric 6 and the inner barrel or the impeller in the speed increasing process is reduced. The first penetrating water inlet rotation speed is 100-300rpm, the first penetrating water inlet rotation speed is 150-250rpm, and the optimal selection is 200 rpm.
In the penetrating water inlet step, the inner barrel 2 and the impeller 3 synchronously rotate in the same direction at a first penetrating water inlet rotating speed, at the moment, under the action of the centrifugal force of rotation, the cashmere fabric 6 synchronously rotates along with the inner barrel 2 and the impeller 3, and the cashmere fabric 6 is limited on the edge of the inner wall of the inner barrel 2; thus, when the cashmere sweater rotates to pass through the water inlet 4 every time, the inflow water flows to the cashmere textiles 6; the incoming water flow sprayed on the cashmere fabric 6 is under the action of the rotating centrifugal force, the fluff on the surface of the cashmere fabric 6 can be quickly soaked by the impact force and the centrifugal force of the water flow, and the centrifugal force generated by rotation can effectively prevent the cashmere fabric 6 from floating in water, ensure the cashmere fabric, the inner barrel 2 and the impeller 3 to be synchronous and have no relative motion, and avoid the friction and the pull on the cashmere fabric; before reaching a first set water level a, the penetrated water flow continuously runs, the surface of the cashmere fabric 6 is gradually wetted, and the surface layer fluff is preliminarily wetted, so that the wetting speed of the fabric is accelerated; and entering a synchronous water inlet step when the first set water level a is reached.
In the step of synchronous water feeding, cashmere fabric 6 is in a semi-suspension state due to surface fluff soaking, the inner barrel 2 and the impeller 3 are synchronously rotated at low speed at intervals, specifically, the synchronous rotation speed is 40-60rpm, and the operation is stopped for 1s after 4-5 s; the cashmere fabric 6 moves synchronously with the water flow and has the tendency of moving downwards when rotating, the cashmere fabric is continuously soaked, the contact between the cashmere fabric 6 and the inner barrel 2 or the impeller 3 is avoided, and the cashmere fabric can be completely soaked in a combined mode of penetrating water inlet and synchronous water inlet.
B. And a washing stage, namely entering the washing stage after the water inlet stage is finished, driving the impeller 3 to rotate forward and backward at intervals at a set washing rotating speed to generate vortex immersion washing water flow, and performing immersion washing decontamination on cashmere fabrics by combining centripetal traction force and buoyancy force of the water flow as shown in figures 3 and 4.
In the stage, the inner barrel 2 is in a static state, and vortex immersion washing water flow in the washing stage is arranged, so that the water flow is driven to form vortex under the water surface when the impeller rotates, and cashmere fabric sinks below the water surface under the action of vortex attraction; if the rotating time of the cashmere fabric along with the water flow is too long, friction between the cashmere fabric and the impeller or rotation of the cashmere fabric per se can be formed, so that the surface of the cashmere fabric is fluffed, and therefore, the cashmere fabric is ensured to be completely immersed in water and not to be contacted with the impeller and to rotate per se by controlling the rotating speed and the stalling ratio of the impeller, and the cashmere fabric floats on the water surface under the action of buoyancy and is fully unfolded and moves relative to the center of the impeller; specifically, the washing speed is set to be 45-60 rpm, the cashmere fabric is rotated for 1-2s and stopped for 2-3s, the cashmere fabric is rotated forward for 3-5 times and reversely for 3-5 times, the centripetal traction force of water flow and the buoyancy combination of water are utilized to carry out immersion washing and decontamination on the cashmere fabric, the vortex water flow is ensured to generate enough downward acting force on the cashmere fabric, and meanwhile, the cashmere fabric is prevented from rotating to cause surface fuzzing and pilling.
The washing uniformity can be ensured by arranging forward and reverse rotation for 3-5 times respectively, and the washing uniformity is preferably 3 times, so that the uneven stress on the surface of the cashmere fabric 6 caused by frequent forward and reverse rotation is avoided. Preferably, the pulsator 3 sets a washing rotation speed at 54 rpm. When the highest water level in the outer barrel of the washing machine is set to be the tenth water level, the first set water level is the second water level, and in order to form expected vortex water flow, the second set water level is the sixth water level in the water inlet stage; and when the water level is at the sixth grade, the vortex water flow generated by the impeller is most obvious, the vortex water flow is enabled to generate enough downward acting force on the cashmere fabric by rotating for 1-2s, and meanwhile, the cashmere fabric is prevented from rotating to cause surface fuzzing and pilling. The dirt degree of the cashmere fabric is light generally, and the adhesive force of the dirt is weak, so that the washing program is set to be 5-7 minutes to meet the cleaning requirement, and the overlong washing time is not beneficial to the protection of the cashmere fabric fibers.
C. And the dehydration stage sequentially comprises a pre-dehydration step, a water spraying dehydration step and a formal dehydration step.
In the stage, the method also comprises an idle discharge step and an inertia discharge step, wherein the idle discharge step is carried out after the discharge valve 5 is opened, and then the pre-dehydration step with the dehydration rotating speed of 350-450rpm is set; then entering a water spraying dehydration step and a formal dehydration step; after the formal dewatering step, an inertial drainage stage is entered. The multi-section dehydration mode can effectively reduce the surface foam residue of the cashmere fabric, the dehydrated cashmere fabric has better hand feeling and visual sense, the fluffing and pilling control on the surface is better, and the fiber stretching deformation of the cashmere fabric is extremely small.
Specifically, the method comprises the following steps of firstly, draining washing water to an empty water level of an empty barrel, and then entering a pre-dehydration step; in the pre-dehydration step, the inner tub 2 and the pulsator 3 are driven to synchronously and gradually accelerate to the set dehydration rotation speed for 20-30s, that is, after accelerating to the set dehydration speed, the operation is carried out for 20-30 s. As the gaps among the cashmere fabric fibers are large, water is easy to remove, the dehydration time of 20-30s is enough to ensure the dehydration effect, and meanwhile, the stretching deformation of the cashmere fibers caused by too long dehydration is avoided. Preferably, the dehydration rotating speed is set to be 350-450rpm, and the cashmere fabric, the inner barrel and the impeller are synchronously and gradually accelerated by arranging the inner barrel 2 and the impeller 3, so that the synchronous acceleration of the cashmere fabric, the inner barrel and the impeller is ensured, and the friction is avoided as much as possible; and accelerated to 350-450rpm, the set dehydration speed in the embodiment is far less than the dehydration speed in the normal procedure, firstly, because the fiber gaps of the cashmere fabric are larger, water is easier to be dehydrated; secondly, the pulling and deformation of the cashmere fabric caused by high speed are avoided, and the shape maintenance of the cashmere fabric is facilitated; thirdly, the cashmere fabric absorbs water a lot, avoids the load to distribute unevenly, takes place to hit the bucket when speed is great. Through the pre-dehydration step, the water content in most cashmere fabrics is pre-extruded, which is beneficial to the next step of water spraying dehydration.
In the pre-dehydration step, most of water in the cashmere fabric is removed, and then the cashmere fabric enters the water spraying dehydration step; referring to fig. 5, in the step of dewatering by spraying water, the water inlet valve and the water outlet valve 5 are opened simultaneously, the inner barrel 2 and the pulsator 3 are driven to rotate synchronously at the same direction by setting the dewatering speed by spraying water, the cashmere fabric 6 rotates synchronously along with the inner barrel 2 and the pulsator 3 under the action of centrifugal force, and the cashmere fabric 6 is limited on the edge of the inner wall of the inner barrel 2; when the cashmere fabric rotates to pass through the water inlet 4 every time, the inflow water flow is intermittently poured on the surface of the cashmere fabric 6, passes through the cashmere fabric under the action of centrifugal force and is discharged to an outer barrel, so that residual foam on the surface layer of the cashmere is taken away, and the residue is further reduced; in addition, in the process of water spraying and dewatering, most of water sprayed on the cashmere fabric 6 is thrown out under the action of centrifugal force, so that after the step of water spraying and dewatering is finished, the water content in the cashmere fabric is not high, the barrel collision at high speed is avoided, the dragging of the cashmere fabric in the dewatering step is reduced, the relative motion of the cashmere fabric and the inner barrel or the impeller is reduced, and the abrasion to the cashmere fabric is reduced.
