Problems solved by technology

However, during the wearing process, due to the characteristics of cotton fiber itself, cotton fiber fabrics are prone to problems such as wrinkles and deformation, which not only affects the appearance of the fabric, but is also not durable
[0003] In order to solve the above problems, anti-wrinkle finishing of cotton fabrics has been started. At present, N-hydroxyl finishing agents are mostly used in the market. This type of finishing agent can effectively improve the wrinkle resistance of cotton fabrics. Will produce free formaldehyde, which is harmful to human health

Abstract

The invention provides a crease-resistant deformation-preventing finishing process for a cotton fabric. The finishing process comprises the following steps: desizing; scouring and bleaching; whitening; crease-resistant finishing; predrying; baking; washing; and drying. According to the invention, modified tea saponin is added in the procedure of scouring and bleaching and process temperature is strictly controlled, so the whiteness of the cotton fabric is improved; as the procedure of whitening is carried out after the procedure of scouring and bleaching and low-temperature whitening is employed in the procedure of whitening, little damage is posed to the cotton fabric, the whiteness of the cotton fabric is further improved, and whiteness maintenance of the cotton fabric after finishing is facilitated; and and a crease-resistant finishing agent prepared from citric acid and polyethylene glycol in proportion is safe and nontoxic, improves the crease-resistant and deformation-preventing effect, and enables the rebounce angle of the cotton fabric to reach 245 DEG or above.

Description

technical field [0001] The invention relates to a fabric finishing process, in particular to a wrinkle-resistant and deformation-resistant finishing process for cotton fabrics. Background technique [0002] Cotton fiber is a kind of natural cellulose fiber. Its microstructure is microfibrils formed by the aggregation of dozens of chain-like cellulose macromolecules. The fibrils are arranged into the sun ring layer, and finally the fibers are formed. The microscopic interior of cotton fibers is a porous material. Due to its own characteristics, it has good air permeability, moisture permeability and outstanding comfort, so it is loved by consumers. However, during the wearing process, due to the characteristics of cotton fiber itself, cotton fiber fabrics are prone to problems such as wrinkles and deformation, which not only affects the appearance of the fabric, but also is not durable. [0003] In order to solve the above problems, anti-wrinkle finishing of cotton fabrics...
