Problems solved by technology

At present, most of the research on the air permeability of plants stays at the static point of view of the structure and characteristics of fabrics, such as the relationship between fabric porosity or plant structural parameters and air permeability of fabrics, and does not involve the influence of fabric timing and processing on air permeability.
[0003] Washing water for denim clothing can form different clothing styles, but there is no report about the impact of washing water for denim clothing on the air permeability of denim itself. The present invention attempts to propose a washing process for denim to explore its impact on denim. The change of fabric structure and its effect on the air permeability of fabric

Abstract

The invention discloses a jean fabric washing process and relates to the field of fabric washing. The jean fabric washing process comprises the following steps of 1) preprocessing jean fabric, 2) after the jean fabric is processed in the step 1), heating primary desizing liquid to 80 DEG C, putting in and washing the jean fabric for 20 min, 3) performing first washing in clean water for 3-5 times,4) performing first dewatering, 5) performing first drying, 6) enzyme-washing the processed jean fabric of the step 5) in washing liquid of 45 DEG C for 35-40 min, discharging the liquid, and controlling the bath ratio to be 1:4-1:9, 7) performing silicone oil treatment on the processed jean fabric of the step 6) through 50 g of silicone oil and 1.6 L of water, 8) softening the processed jean fabric of the step 7) for 15-25 min and at 25-35 min by mixing softening agent with water, 9) performing second dewatering, and 10) performing second drying. The jean washing process can produce jean fabric good in breathability and soft in hand feeling.

Description

technical field [0001] The invention relates to the field of fabric washing, in particular to a denim washing process. Background technique [0002] The air permeability of fabric directly affects the comfort of clothing. The main factors affecting the air permeability of fabric are fabric structure, fiber properties, yarn structure and environmental conditions. At present, most of the research on the air permeability of plants stays at the static point of view of the structure and characteristics of fabrics, such as the relationship between fabric porosity or plant structural parameters and air permeability of fabrics, and does not involve the influence of fabric timing and processing on air permeability. [0003] Washing water for denim clothing can form different clothing styles, but there is no report about the impact of washing water for denim clothing on the air permeability of denim itself. The present invention attempts to propose a washing process for denim to explo...
