Problems solved by technology

At present, most of the research on the air permeability of plants stays at the static angle of the structure and characteristics of the fabric, such as the relationship between the porosity of the fabric or the structural parameters of the plant and the air permeability of the fabric, and does not involve the influence of the timing and processing of the fabric on the 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 fabric itself. The present invention attempts to propose a washing process for denim fabric to explore its impact on denim fabric. The change of fabric structure and its effect on fabric breathability

Abstract

The invention discloses a water washing technology of denim fabric, and relates to the field of fabric water washing. The water washing technology comprises the following steps of 1, pretreatment of the denim fabric; 2, steaming, wherein the denim fabric treated in the step 1 is placed in a steam cylinder to be preheated for 30 s, then the denim fabric is taken out to be cooled for 30 s, and the following steps are repeated for 3 times; 3, enzyme wash, wherein the denim fabric treated in the step 2 is put into washing liquid of 45 DEG C to be subjected to enzyme wash for 35-40 min, and then the liquid is drained; 4, water washing, wherein the denim fabric is repeatedly washed with clear water 3-5 times; 5, dehydration for the first time; 6, drying for the first time; 7, passing through silicone oil, wherein the denim fabric treated in the step 6 passes through the silicone oil according to the proportion of 50 g of the silicone oil and 1.6 L of water; 8, softening, wherein after softening agent and the water are mixed, the fabric obtained after the step 7 is softened, the treating time is 15-25 min, and the temperature is 25-35 DEG C; 9, dehydration for the second time; 10, dryingfor the second time. By means of the water washing technology, the denim fabric good in breathability and soft in hand feeling can be obtained.

Description

technical field [0001] The invention relates to the field of fabric washing, in particular to a washing process for denim fabrics. 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 angle of the structure and characteristics of the fabric, such as the relationship between the porosity of the fabric or the structural parameters of the plant and the air permeability of the fabric, and does not involve the influence of the timing and processing of the fabric on the 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 fabric itself.
