Description

Technical Field

[0001] The utility model relates to the technical field of knitting fabric processing equipment, in particular to an efficient automatic fabric pretreatment machine. Background Art

[0002] Knitting fabric is a kind of fabric manufactured through the knitting process. It is composed of a series of coils connected in series with each other, which endows the knitting fabric with many unique properties. Knitting fabric usually has good elasticity and ductility, and can be stretched and restored to its original state to a certain extent, thus providing a comfortable wearing experience, especially suitable for making close-fitting clothes such as underwear and sportswear. In terms of texture, knitting fabric can present a variety of textures ranging from soft and delicate to thick and warm, meeting the needs of different seasons and uses. The fabric has good breathability, which helps to keep the skin dry. Due to the coil structure of knitting, the texture of knitting fabric is relatively soft, the surface is relatively smooth, and the touch is comfortable. In terms of appearance, knitting fabric can have various patterns and designs, and through different knitting stitches and yarn combinations, rich and diverse visual effects can be created. In terms of uses, in addition to the common clothing field, knitting fabric is also widely used in household items such as bedding and pillowcases, as well as in industrial and medical fields.

[0003] In the printing and dyeing process of knitting fabric, there are many links that need special attention and treatment. Among them, due to the unique properties of knitting fabric itself, such as curling and easy stretching and elongation, specific treatment methods need to be adopted during the printing and dyeing process. Specifically, knitting fabric needs to go through two important steps: flat washing and shrinking and scouring. This is because the special structure and material of knitting fabric determine that it must be fully and properly pretreated before printing and dyeing. Before the knitting fabric enters the flat treatment, there is also a key task, that is, to effectively remove various natural impurities contained in its fibers. These natural impurities include pectin, nitrogen-containing substances, pigments, and cottonseed hulls, etc.

[0004] The existing knitting fabric is prone to drawstrings and deformation, resulting in problems such as uneven fabric tension and excessive stretching during the processing, affecting the quality and dimensional stability of the fabric. Moreover, during the handling and transportation of textiles, dust and impurities are easily adhered to the fabric, affecting the subsequent printing and dyeing effect and the quality of the fabric.
