Embodiment 1

[0014] This embodiment is a kind of post-finishing production method that can improve the quality of knitted denim products. Taking a kind of pure indigo dark blue pure cotton knitted denim as an example, it illustrates the process of producing high-quality knitted denim by using the open-width loose post-finishing method method:

[0015] After step S1, a plurality of pieces of knitted denim are connected in open width to form large rolls or open folded rolls; then the cloth rolls are passed through step S2 in a state of open width loose and low tension; in open width loose cold stacking On the machine, the finishing aid is pad-rolled on the knitted denim fabric, the pad-pad temperature is room temperature, and the fabric is rolled into a roll with an open-width A-frame when the cloth is released; Step S4, under a condition of open-width loose type and low tension, use multiple washing tanks to prewash, neutralize, wash, Soaping and hot water washing treatment, remove the flo...

Embodiment 2

[0017] This embodiment is a kind of post-finishing production method that can improve the quality of knitted denim products. Taking a kind of pure indigo dark blue pure cotton knitted denim as an example, it illustrates the process of producing high-quality knitted denim by using the open-width loose post-finishing method method:

[0018] After step S1, multiple pieces of knitted denim are connected in open width to form large rolls or open-width folded rolls; then the cloth rolls are passed through step S2 in the open-width loose-type low-tension state, and are cold-stacked in open-width loose type. On the machine, the finishing agent is pad-rolled on the knitted denim fabric, the pad-pad temperature is at room temperature, and the cloth is rolled into a cloth roll with an open-width A-frame when the cloth is released; S4, under a condition of open-width loose type and low tension, use multiple washing tanks to prewash, neutralize, wash, and soap the knitted denim after the p...

Embodiment 3

[0020] This embodiment is a kind of post-finishing production method that can improve the quality of knitted denim products. Taking a kind of pure indigo dark blue pure cotton knitted denim as an example, it illustrates the process of producing high-quality knitted denim by using the open-width loose post-finishing method method:

[0021] After step S1, a plurality of pieces of knitted denim fabrics are connected in open width to form large rolls or open-width folded rolls; On the stacking machine, the finishing agent is pad-rolled on the knitted denim fabric, the pad-rolling temperature is room temperature, and the cloth is rolled into a cloth roll with an open-width A-frame when the cloth is discharged; then step S3 is continuously rotated and stacked by the A-frame for 48 hours and then passed through Step S4, under a condition of open-width loose type and low tension, use multiple washing tanks to prewash, neutralize, wash, Soaping and hot water washing treatment, remove ...

Abstract

The invention discloses an after-finish production method capable of improving the product quality of the knitted denim. The after-finish production method comprises the following steps of S1, open width curling preparation; S2, open width loose cold stacker padding; S3, open width A-shaped frame rotation and stacking; S4, open width loose padding, washing and drying; S5, forming and preshrinking.The after-finish production method has the advantages that the method is novel in design, knitted denim is innovatively padded through open width loose low tension, rotated, stacked and subjected tomulti-groove open width loose padding and washing so that knitted denim grey cloth which is poor in color fastness can be uniformly soaked in an after-finish auxiliary for a long time, then not so much transverse straight drawing force is added, and after the surface dyeing on the knitted denim is removed and the color is fastened, the produced knitted denim is high in color fastness, stable in gram weight, less in surface dyeing, stable in twisting degree and shrinkage rate and few in cloth surface close fold. The high-quality knitted denim has a good market prospect.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a finishing production method capable of improving the quality of knitted denim products. Background technique [0002] Dyed fabrics can be divided into yarn-dyed fabrics (dyed yarn first, then weaved yarn-dyed fabrics, and then finished finishing) and dyed fabrics (weaving gray fabrics with white yarns first, then pre-treating white gray fabrics, then dyeing, and then finishing). Finishing), denim fabric belongs to the former. Classified according to the weaving method, denim can be divided into two types: woven denim with relatively early development and knitted denim with relatively late development. The denim dyed yarn dyed with indigo is directly woven on the knitting machine without sizing. Therefore, the traditional finishing method of woven denim includes the following steps: singeing, desizing, mercerizing, shaping, and pre-shrinking. However, because knitte...
