Embodiment 1

[0009] A specific production process of the all-cotton leno yarn-dyed fabric is as follows: cotton yarn bleaching → dyeing → warping → sizing → weaving → gray fabric repair → singeing → desizing → mercerizing → shaping → preshrinking, this The difference between the production process and the traditional fabric production process is:

[0010] In the weaving process: (1) The other warp shaft of the hollowed out part adopts spring pressure type warp let-off, and the pressure is controlled at 82kg, so that the warp let-off is stable and the warp release is even, ensuring the leno jacquard is clear and full! (2) Adopt twisted heald loosening device, when the twisted warp is fully open, ensure that the tension of the small shaft part and the upper and lower layers of the ground tissue are consistent, and the loosening amount of the warp yarn is controlled at 2.5cm; the broken warp is reduced, and the weaving efficiency is increased to 90%. (3) When skipping the heddle, let the skei...

Embodiment 2

[0014] The second specific production process of the all-cotton leno yarn-dyed fabric is as follows: cotton yarn bleaching → dyeing → warping → sizing → weaving → gray fabric repair → singeing → desizing → mercerizing → finalizing → preshrinking, The difference between this production process and the traditional fabric production process is:

[0015] In the weaving process: (1) The small warp shaft of the hollowed out part adopts spring-loaded warp let-off, and the pressure is controlled at 90kg, so that the warp let-off is stable and the warp release is even, ensuring that the leno jacquard is clear and full! (2) Adopt twisted heald loosening device, when the twisted warp is fully open, ensure that the tension of the small shaft part and the upper and lower layers of the ground tissue is consistent, and the loosening amount of the warp yarn is controlled at 2.8cm; the broken warp is reduced, and the weaving efficiency is increased to 90%. (3) When skipping the heddle, let the...

Embodiment 3

[0019] The third specific production process of the all-cotton leno yarn-dyed fabric is as follows: cotton yarn bleaching → dyeing → warping → sizing → weaving → gray fabric repair → singeing → desizing → mercerizing → finalizing → preshrinking, The difference between this production process and the traditional fabric production process is:

[0020] In the weaving process: (1) The small warp shaft of the hollowed out part adopts spring-loaded warp let-off, and the pressure is controlled at 100kg, so that the warp let-off is stable and the warp is released evenly, ensuring that the leno jacquard is clear and full! (2) The skein heald relaxation device is adopted to ensure that the tension of the small shaft part and the upper and lower layers of the ground tissue is consistent when the skein warp is fully opened, and the warp relaxation is controlled at 3cm; warp breakage is reduced, and the weaving efficiency is increased to 90%. (3) When jumping brown, let the twisted brown y...

Abstract

The invention discloses a production process of a cotton leno yarn-dyed fabric with good comfort and air permeability, soft feeling, and excellent water absorbability and wet permeability. The production process comprises the following steps: cotton yarn bleaching - dyeing - warping - sizing - weaving - grey cloth reconditioning - singeing -desizing - mercerizing - forming -pre-shrinking. The production process is characterized in that: in the weaving process: (1) pressurization and letoff are performed on a hollow part by a small shaft; (2) a doup release device is adopted to ensure the tension of the small shaft part to be the same as that of the upper yarn and the lower yarn of ground weave when doup warps fully open, and the warp end release amount is controlled at 2.5-3cm; (3) doup yarns are 0.5-1.0cm higher than ground harnesses at heald level time; and (4) a wefting mode is a large wefting travel mode with the inserting angle being 60-65 degrees and withdrawing angle being 310-315 degrees. In the singeing process, the direction of burner flame is changed into tangential singeing; and a mid-high alkali concentration singeing method and a three-step expanding adjustment method are adopted in the mercerizing and forming processes.

Description

technical field [0001] The invention relates to a new production process of leno yarn-dyed fabric. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people are developing in the direction of differentiation and individualization. Especially for spring and summer clothing, it is required that the fabric has the characteristics of moisture absorption, breathability, environmental protection and multi-functionality. Fabrics cannot meet the above-mentioned latest requirements of people. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a production process of an all-cotton leno yarn-dyed fabric that is comfortable, breathable, soft to the touch, and excellent in hygroscopicity and moisture conductivity. [0004] In order to solve the above-mentioned technical problems, the production process of the all-cotton leno yarn-dyed fabric described...
