Problems solved by technology

In addition, the cloth tape is too short. Under the same dyeing process conditions, it is necessary to use the dyeing machine to perform multiple batches of dyeing and washing to complete the dyeing process of a given amount of fabrics. This not only increases water consumption and energy consumption, but also cannot meet the requirements of improving production efficiency. Require

Abstract

The invention discloses a high-efficiency polyester fabric dyeing method, and belongs to the technical field of dyeing. According to the technical scheme, polyester fabrics which do not exceed the maximum load of dyeing equipment are simultaneously dyed in dyeing equipment in a form of a first cloth belt and a second cloth belt, wherein the head and the tail of the first cloth belt are connected to form a ring, the head end of the second cloth belt is connected to the position where the head and the tail of the first cloth belt are connected, and the length of the second cloth belt is less than or equal to the length of the first cloth belt; the first cloth belt comprises one piece of polyester fabric or is formed by splicing at least two pieces of polyester fabrics end to end, and the second cloth belt comprises one piece of polyester fabric or is formed by splicing at least two pieces of polyester fabrics end to end; and the length of the first cloth belt and the length of the secondcloth belt are both smaller than the longest cloth capacity of a single tube of the dyeing equipment. The high-efficiency polyester fabric dyeing method has the advantages of high dyeing efficiency and low water consumption and low energy compared with the conventional single-tube single-ring dyeing.

Description

technical field [0001] The present invention relates to a kind of dyeing method, more specifically, it relates to a kind of efficient polyester fabric dyeing method. Background technique [0002] Polyester is an important variety of synthetic fibers. It is the trade name of polyester fiber in my country. It is made of polyterephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials. The fiber-forming high polymer obtained by esterification or transesterification and polycondensation reaction - polyethylene terephthalate (PET), the fiber made by spinning and post-processing. Polyester fabrics woven from polyester are widely used because of their high strength, good elasticity, and good wear resistance. [0003] The dyeing of polyester fabrics is usually done in a rope-like intermittent dyeing machine in an overflow dyeing machine. Multiple pieces of polyester fabric are connected end to end to form a rope-like cloth tape. When feeding th...
