Technical Field

The invention relates to a high-whiteness grey cloth finishing process, and belongs to the technical field of textile manufacturing.

Background

The grey cloth is natural color cotton cloth for printing and dyeing processing. Industrial grey fabrics are generally referred to as fabrics, or laminated, sized, etc. The traditional cloth splicing finishing process has the defects of high cost, large sewage discharge amount, BOD (biochemical oxygen demand) in water, high COD (chemical oxygen demand), high treatment cost, increased environmental burden, complex working procedures, relative waste of labor and time, large consumption of steam, water and electricity and high energy consumption due to the large use of alkali and surfactant. The chlorine bleach is harmful to human body and pollutes air.

The chitosan is prepared by extracting chitin as a raw material, is insoluble in water, can be dissolved in dilute acid, and can be absorbed by a human body. Chitosan is a primary derivative of chitin. The chemical structure of the polysaccharide is a high molecular basic polysaccharide polymer with cations, and the polysaccharide has unique physical and chemical properties and biological activation function. The composite material of chitosan and esters can effectively improve the flexibility, tensile strength, environmental protection performance and environmental protection performance of the textile grey cloth.

Disclosure of Invention

The invention aims to provide a high-whiteness grey cloth finishing process, which is simple in preparation method, high in environmental protection performance of the prepared grey cloth, simple in process, low in production cost, nontoxic and harmless in adopted raw materials, environment-friendly and pollution-free.

The invention provides a high-whiteness grey cloth finishing process, which comprises the following process steps: singeing grey cloth → washing → cold batch → washing → oxygen bleaching → dyeing → fixation → washing → drying; wherein, a desizing enzyme auxiliary agent is adopted in the cold batch process; the oxygen bleaching process adopts a scouring enzyme assistant, the color fixing process is to use glacial acetic acid to adjust the pH value of a dye bath to 5.6-6, the color-fixed all-cotton grey cloth is subjected to color fixing agent removal treatment, the treatment temperature is controlled to be 111-115 ℃, and the treatment time is 30-40 minutes; the cold-batch process is to roll and desize the enzyme auxiliary agent under the condition that the water temperature is controlled to be 50-60 ℃, the mangle expression is 90-100%, the fabric is rolled and soaked twice, and meanwhile, the fabric is coiled and rotated on an A-shaped frame, 8 revolutions per minute and is piled for 20-24 hours at normal temperature; the desizing enzyme auxiliary is prepared from the following raw materials in percentage by weight:
