Embodiment 1

[0008] Embodiment 1: pretreatment technological process of linen fabric:

[0009] Singeing - padding compound enzyme - falling cloth heat preservation and stacking - chlor-alkali oxygen treatment - wet cloth half silk

[0010] Light---wax removal and wrinkle removal---inspection, packaging,

[0011] Singeing process: crater: 2 positive and 2 reverse, vehicle speed: 80M / min, steam extinguishing, crater temperature: 900℃~1100℃. (It has been found through experiments that if the burner temperature is too low, hairiness cannot be removed completely, and if it is too high, it may cause a decrease in strength after overburning. Therefore, it is determined to be between 900-1100°C and the speed is about 80m / t.)

[0012] Composite enzyme treatment: Kangdien wide temperature desizing enzyme KW-40 2g / L

Abstract

The invention discloses a pretreatment method of a bast fiber fabric short process. The pretreatment method of the short process comprises three technological processes which respectively are an efficient composite biological enzyme cold dome pretreatment process, a bast fiber fabric chlorine alkali oxygen one bath pretreatment process and a bast fiber fabric wet cloth half mercerization process. Compared with the prior art, energy consumption of the process is reduced by about 30%; various assistants such as caustic soda, a penetrating agent, a scouring agent and a stabilizer are replaced, the quantity of wastewater effluent is reduced, meanwhile alkaline substance content in wastewater is reduced, pollution is reduced, the pretreatment effect of the bast fiber fabric is improved, impurities, thick liquid, wax, pigment and the like of cotton fabrics are effectively removed to enable the fabrics surfaces to be bright and clean, enhanced in whiteness, soft and smooth in hand feel, hydrophilism, water diffusion degree and the like of the bast fiber fabric are obviously improved, and the rate of dyeing and leveling property are improved.

Description

technical field [0001] The invention belongs to the pretreatment process of hemp fabrics such as ramie and flax, and particularly belongs to the energy-saving and environment-friendly short-flow pretreatment process of hemp fabrics. Background technique: [0002] The traditional pretreatment process of hemp fabric needs to go through multiple washing processes and at least 4 drying processes. The washing consumes a lot of water resources, and the use of steam as the drying heat source in the drying process consumes a lot of energy; more importantly, after many The various properties of the dried fabrics are damaged to varying degrees, which affects the product quality. Contents of the invention [0003] The purpose of the present invention is to solve the problem that various properties of the hemp fabrics in the known pretreatment process are damaged to varying degrees and affect the product quality. [0004] The technical scheme adopted in the present invention is: a s...
