Background technology
In recent years, the raw material of denim fabric use more and more diversified, particularly functional raw material, such as
CoolMax, Thermolite, coffee carbon and coconut palm carbon etc., these are essentially all fibre in differentiation or in spinning solution
Nano-powder is added, is mostly used for the weft yarn of denim fabric, and cannot warp thread directly be done using indigo dyeing, moisture absorption is breathed freely pair
The wearability of clothes is very crucial, and generally using functional yarn or flaxen fiber, and general functional moisture absorption is breathed freely yarn
For weft yarn, flaxen fiber do warp thread be unfavorable for weaving and wearing comfort it is bad, in addition, elastic denim fabric is always cowboy
The trend of garment industry, and high-elastic denim fabric is even more much favored by the market, but simultaneously there is also the problem of excessive of shrinking, it is a kind of
The high-elastic denim fabric of cotton bag cotton and its postfinishing process, the denim fabric warp thread use cotton bag cotton cored weaving yarns, ox can be used
Young indigo dyeing, weft yarn use cotton bag twin-core weaving yarns;Than traditional cowboy more preferably, use is specific for the denim fabric sucting wet air permeability
Postfinishing process, ensure that its broadwise is shunk within -10%, and its elastic extension, more than 35%, elastic recovery rate exists
More than 90%, manufactured denim fabric has the characteristics that high added value and high benefit.

Between 35m/min, scrape bubbler 2, glue blanket master cylinder air pressure 0.4mpa and drying woollen blanket air pressure 0.2mpa.
After tested, the broadwise elastic extension of the high-elastic denim fabric of cotton bag cotton is 52~55%, elastic recovery rate
For 92%~95%, broadwise washing shrinkage is -8~-10%.
The high-elastic denim fabric of cotton bag cotton, broadwise Suo≤10% made of the utility model, substantially reduce clothing loss with
And ready-made clothes deformation, the denim fabric sucting wet air permeability is fabulous, and manufactured jeans are comfortable and easy to wear, can produce in enormous quantities.
