Long vehicle low-temperature steaming technology for fiber textiles and equipment

Abstract

The invention discloses a long vehicle low-temperature steaming technology for fiber textiles and equipment. The technology comprises the following steps of (1) preparing gray cloth, (2) singeing, (3) desizing, (4) scouring, (5) rinsing and (6) drying. The invention further discloses long vehicle low-temperature steaming equipment for fiber textiles. The equipment comprises a scouring mechanism. The scouring mechanism has an immersion barrel and a steaming case connected with the immersion barrel, wherein the steaming case is provided with a case body equipped with an accommodating cavity; a steaming cavity steaming and heating textiles and a temperature balancing cavity preventing steam coagulation and on the upper part of the steaming cavity are disposed in the case body; the case body is equipped with a first steam supplying assembly and a second steam supplying assembly both providing high-temperature steam to the steaming cavity and the temperature balancing cavity. The steaming equipment can effectively reduce equipment energy consumption, save energy and improve production efficiency; and the long vehicle low-temperature steaming technology has short circulating, high efficiency, and can reduce water and energy use.

Description

technical field [0001] The invention relates to the technical field of textile processing technology, in particular to a long-car low-temperature steam process and equipment for fiber textiles. Background technique [0002] Cotton fabric refers to fabrics woven with cotton yarn or cotton and cotton chemical fiber blended yarn. The material of cotton fabric is mainly composed of cotton fibers. The cotton fibers in these undyed gray cloths contain pectin, wax These natural impurities mainly exist in the cuticle and primary cell wall of cotton fiber, plus the oil on the fiber, the size on the warp yarn and dirt. The presence of these impurities not only makes the fabric yellow in color, rough in hand, but also poor in water absorption. For this reason, the first step in the dyeing and finishing of cotton-type fabrics is to carry out pretreatment to it, and the quality of pretreatment plays a key role in the quality of finished products. The sizing treatment before weaving inc...

Problems solved by technology

[0007] The above-mentioned fabric pretreatment method is inseparable from chemical auxiliaries, especially the fabric dyeing pretreatment process, which is recognized by the textile industry as the "three highs" of high water consumption, high wastewater discharge, and high chemical auxiliaries consumption. This link requires Workers put caustic soda, hydrogen peroxide, refining agent, penetrating agent, degreasing agent and other large and varied chemical additives into the water one by one, and make pre-treatment working liquid to scour the fabric. The scoured water is called "waste water". Let go; In addition to the large consumption of water resources, a large amount of steam is required for pretreatment, and problems such as steam heat transfer and condensate recovery cause a large amount of waste of
