Washing method and washing machine for cashmere fabric

Abstract

The invention provides a washing method for cashmere fabrics and a washing machine, comprising the following steps: a water inlet step, a washing step, driving the drum to rotate forward and backward at intervals, lifting ribs on the drum to push to form vortex water flows in different directions, and lifting ribs The inner cavity is filled with water and turned out of the water surface, and the water is poured out, impacting the cashmere fabric to decontaminate; the dehydration step includes the emptying stage of draining the washing water to the water level of the empty bucket, the buffer dehydration stage of dehydration at a speed of 120‑200rpm, and the dehydration stage of dehydration at a speed of 500‑ The official dehydration stage of dehydration at a speed of 700rpm. Accelerate the wetting speed of the fabric and improve the uniformity of washing; by setting a suitable rotating speed, the height of the lifting ribs can be increased to generate a greater impact force to impact the decontamination of the cashmere fabric. During the buffer dehydration process in the dehydration step, the cashmere fabric is close to the drum wall without relative movement, which avoids friction and pulling on the cashmere fabric, reduces eccentricity, and is beneficial to shape retention of the cashmere fabric.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing method for cashmere fabrics and a washing machine with the washing method. Background technique [0002] Cashmere scarves, shawls, cashmere sweaters and other cashmere fabrics are common high-grade cold-proof textiles in winter. Cashmere fabrics have the advantages of delicate and plump appearance, soft and waxy feel, light and comfortable wearing, and good warmth retention. This is mainly due to the lightness of cashmere fibers. , soft, warm, moisture absorption and other natural characteristics, but these natural characteristics have also become difficult points in the washing process. [0003] At present, washing machines do not have a special washing program for washing cashmere fabrics. Most washing machines are equipped with wool or hand washing programs, but cashmere fabrics have significantly different characteristics from wool fabrics. Cash...

Problems solved by technology

When cashmere fabrics are washed with existing wool or hand washing procedures, the cashmere fabrics cannot be completely wetted during the water intake process, and they always float on the water surface during the washing process and are not easy to get wet. Dehydration, the washing machine lasts for a long time, and the cashmere fabric cannot meet the requirements of high cleaning, low wear, and no pilling on the surface during the entire program operation.

[0004] Therefore, cashmere textiles are light in weight, and the surface fiber fluff has certain water repellency, which is not easy to get wet. It is easy to float on the water surface during washing, and it takes a long time to soak to get wet; and cashmere fibers will produce adhesion deformation after excessive rubbing and beating. Reduce the beating and rubbing of cashmere fabrics in the washing process; and because cashmere fabrics are highly absorbent, the weight of cashmere sweaters after being completely soaked is relatively heavy. Taking ordinary cashmere sweaters as an example, a cashmere sweater with a dry weight of 200g is completely After soaking, the weight can reach 1200g, and the moisture content can reach 500%. The eccentricity of the rotation of the drum during single-piece washing is relatively large, causing the drum to fail to achieve balance. The process of repeated even distribution and balance will cause considerable wear and tear on the cashmere fabric. Severe pilling on the surface; high-speed dehydration of cashmere fabrics when the moisture content is high, has a certain pull on the cashmere fabric, resulting in deformation of the cashmere fabric; in short, it affects its aesthetics, warmth and external feel
