Technical Field

The invention relates to the technical field of textile machinery, in particular to a yarn grinding device with adjustable yarn grinding pressure.

Background

Textile machines are the various mechanical devices required to process natural or chemical fibers into textile products. The different fibers such as cotton, hemp, silk and wool are processed into textiles by different procedures, and the required machines are various and various. Textile machines are generally classified according to the production process, and are counted as: spinning equipment, weaving equipment, printing and dyeing equipment, after-finishing equipment, chemical fiber spinning equipment, reeling equipment and non-woven fabric equipment. The after-finishing equipment is a process for improving the appearance and the hand feeling of the fabric and increasing the wearability. It can be divided into the following according to the process categories: (1) processes for stabilizing the fabric morphology, such as tentering, preshrinking, and heat setting; (2) processes for improving the appearance of fabrics, such as calendering, electro-optic, embossing, creping, sanding, and napping; (3) endowing the fabric with good hand feeling technology, such as softness, super softness, crease resistance, stiffness and the like; (4) special clothing performance technology, such as antistatic, antibacterial, deodorant, mildew-proof, moth-proof, antifouling, water-repellent, oil-repellent, flame-retardant, ultraviolet radiation-proof, etc. In the fabric post-treatment process, special post-treatment equipment is required. The sanding is a common post-treatment process, and the sanding is characterized in that a layer of fabric with a short fluff layer feeling is formed on the surface of the fabric through the friction action of a sanding machine and a carborundum leather, so that the original characteristics are kept, a new style is given to the fabric, the heat retention property and the softness are increased, the fabric is thick, soft and soft, the texture is rich, the fabric has the characteristic of no fading, the color is ever new, and the fabric is suitable for winter heat retention products and products used next to the skin. However, sanding is only for cloth, sanding only polishes the surface of cloth, the hand feeling and the fitting comfort are not ideal, in addition, in the sanding processing of the surface of the cloth, the abrasion of the yarn connecting part is easily caused, and the sanded cloth has the problem of easy hair falling. The cloth woven by the method not only has the feeling of a short fluff layer and good hand feeling and fitting comfort, but also can not cause the abrasion of the yarn joint and has no problem of hair falling. Because the yarns have various types and varieties, the addition of different yarn grinding pressures is realized by a special structure, and the yarn grinding of the yarns of various types and varieties is realized.
