Embodiment 1

[0014] A kind of processing technology of soft anti-fading denim, its preparation process is:

[0015] 1) The preparation process of nano-silver oxide is: mix sucrose ester, silver nitrate and 1.4% NaOH aqueous solution in a mass ratio of 6 / 11 / 100, react at 36°C for 50min, place for 20h, and centrifuge at 3800r / min, the product Wash with absolute ethanol and distilled water three times in sequence, and dry the washed product in a vacuum oven at 60°C for 1 day to obtain nano-silver oxide;

[0016] 2) The preparation process of the modified polyester fiber is as follows: mix nano-silver oxide with polyester chips, the mass ratio of nano-silver oxide and polyester chips in the mixture is 0.2 / 100, and then add active polypeptide accounting for 0.1% of the mass of polyester chips , melted at 265°C, and then extruded from the spinneret hole of the spinneret at 265°C, cooled and solidified into filaments in water to obtain a modified polyester fiber, wherein the amino acid sequence o...

Embodiment 2

[0020] A kind of processing technology of soft anti-fading denim, its preparation process is: at first, the preparation process of nano-silver oxide is: sucrose ester, silver nitrate and 1.6% NaOH aqueous solution are mixed according to mass ratio 8 / 14 / 100, in 39 React at ℃ for 60 minutes, place it for 24 hours, centrifuge at 4000r / min, wash the product three times with absolute ethanol and distilled water in turn, and dry the washed product in a vacuum oven at 60℃ for 1 day to obtain nano-silver oxide; The preparation process of the modified polyester fiber is as follows: mix nano-silver oxide with polyester chips, the mass ratio of nano-silver oxide and polyester chips in the mixture is 0.5 / 100, then add active polypeptide accounting for 0.2% of the weight of polyester chips, Melt at 275°C, then extrude the melt from the spinneret hole at 275°C, cool and solidify in water to form filaments, and obtain modified polyester fibers, in which the amino acid sequence of the active p...

Abstract

The invention discloses a processing technology of soft fading-prevention denim. The processing technology comprises the steps of preparation of modified polyester fiber, preparation of yarn and yarnintertwining. The denim processed through the processing technology has an excellent fading-prevention effect; meanwhile, the soft fading-prevention denim has the advantages of being air and water vapor permeable, tender in hand feeling, and comfortable to wear; the processing technology is simple, low in cost and high in automated degree; meanwhile, in the processing process, fiber resources arefully utilized, and the requirement for environmental protection is met.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a processing technology for soft and fade-resistant denim. Background technique [0002] With the continuous improvement of material living standards, people's pursuits are also constantly changing. Basic needs such as food and clothing have gradually become a thing of the past, and health and comfort have become the current standard. People put forward higher requirements for the quality of clothing fabrics. Fashionable, healthy, comfortable and casual clothing is more and more favored by consumers, and clothing fabrics are developing in the direction of high-end, diversification and functionalization. Differentiated fiber fabrics such as lightweight, warm, moisture-absorbing, breathable, soft and anti-fading are favored by consumers. [0003] Prior art, such as the Chinese invention patent with the authorized announcement number CN 104032519 B, discloses a dyeing process of anti...
