[0007] In the above four patents, the corresponding washing techniques are stone grinding, potassium permanganate rinsing, enzyme washing, and chlorine bleaching. The common point is that after the fabric is dyed, physical or chemical methods are used to fade the fabric to achieve the effect of washing. Therefore, the treatment process requires a large amount of water, and the faded dye will enter the water, causing the COD of the wastewater to rise, so the discharge pressure is also greater

Embodiment 1
[0033] A manufacturing process of a denim-style fabric, comprising the steps of:
[0034] (1) material selection: select the core-spun yarn, and the core-spun yarn includes a core layer and a cortex;
[0035] (2) weaving: weaving the core-spun yarn into a knitted gray cloth;
[0036] (3) Dyeing: Dyeing the knitted gray cloth to color the cortex of the core-spun yarn to obtain dyed cloth;
[0037] (4) Physical friction: perform physical friction treatment on the dyed fabric, and use physical friction treatment to brush off the cortex of part of the core-spun yarn to expose the core layer.
[0038] Wherein, the yarn count of the core-spun yarn is 20S. In other alternative embodiments, the yarn count of the core-spun yarn can be 15S, 16S, 17S, 18S, 19S, 21S, 22S, 23S, 24S, 25S, 27S, 29S, 30S, 31S, 32S, 33S, 34S, 35S, 36S, 37S, 38S, 39S, 40S, etc.
[0039]Wherein, the core layer is polyester fiber, and the denier of the polyester fiber is 150D. In other alternative embodiment...
Embodiment 2
[0052] The difference between this embodiment and embodiment 1 is:
[0053] Wherein, the core layer is polypropylene fiber, the denier of polypropylene fiber is 75D, the cortex is cotton fiber, the bath ratio of the step (3) dyeing treatment is 1:6, the temperature is 60°C, the time is 30min, and the dye For reactive dyes.
Embodiment 3
[0055] The difference between this embodiment and embodiment 1 is:
[0056] Wherein, the core layer is polyester, the denier of polyester is 100D, the cortex is modal, the bath ratio of the step (3) dyeing treatment is 1:6, the temperature is 60°C, the time is 60min, and the dye is a reactive dye .

Abstract
The invention relates to the technical field of preparation of fabrics, and particularly to a preparation process of a denim-style fabric, including the steps of (1), providing core-spun yarn which consists of a core and a covering; (2), weaving, particularly weaving the core-spun yarn into knitted grey cloth; (3), dyeing, to be specific, dyeing the knitted grey cloth, coloring the covering of thecore-spun yarn to obtain dyed cloth; (4), physical rubbing, to be specific, physically rubbing the dyed cloth to remove a part of the covering of the core-spun yarn so as to expose the core. The core-spun yarn consisting of fibers having different properties is adopted in the preparation process, specific dyestuff is utilized in the dyeing process, the covering of the core-spun yarn is colored while the core is not colored, and thus, the effect of ring dyeing of the yarn by the dyestuff is achieved; further, by the brushing process, the core is exposed irregularly, and a denim washing effectis achieved.
Description
technical field [0001] The invention relates to the technical field of fabric production, in particular to a process for fabricating denim-style fabrics. Background technique [0002] Traditional denim is mainly woven with blue warp and white weft. The finished product is hard, heavy, poor in air permeability and elasticity, and the variety is too single. Knitted fabric has the characteristics of light and thin fabric, good air permeability and comfortable wearing. It is especially suitable for the development of soft and elastic denim, and is applied to children's clothing, pajamas, underwear, T-shirts, etc. In recent years, the research on knitted denim fabric has been increasing day by day. At present, knitted denim fabrics are mainly dyed yarns first, and then interwoven with loops to form fabrics. Then, in order to achieve the washing effect of denim fabrics, that is, the sense of depreciation or color layering, it is necessary to carry out proper washing after dyeing....
