Embodiment 1

[0022] Embodiment 1: weave 9.8tex (yarn number) * 2 320*290*165 on the air-jet loom, 1 / 1 organization fabric (warp yarn and weft yarn after number 9.8 number single yarn 2 plying, warp direction density 320 / 10 cm, weft density 290 threads / 10 cm, fabric width 165 cm, 1 / 1 plain weave) process:

[0023] (1) Wrap 9.8tex polyester cotton with single yarn and ply, then add 960 T twist;

[0024] (2) Place the twisted yarn in a place with the same temperature and humidity as the workshop (temperature 25.5-27.5°C, relative humidity 73-78%), and naturally twist for more than 72 hours;

[0025] (3) warp with batch warping machine (680 head parts per shaft), and use 8 warp shafts to parallel shafts on the sizing machine without sizing;

[0026] (4) Apply 8 heald frames (conventional 4 pieces) to the shaft of the combined yarn with 685 healds on each heald frame, and use a steel reed with 155 / 10cm reed teeth to reed into a weaving shaft. 175 cm wide.

[0027] (5) Hang up the reeded lo...

Embodiment 2

[0031] Embodiment 2: Weaving 12tex (yarn number) * 2 300*260*165 1 / 1 organization fabrics (warp yarn and weft yarn after number 12 number single yarn 2 plying, warp direction density 300 / 10 centimeters on air-jet loom , weft density 260 threads / 10cm, fabric width 165cm, 1 / 1 weave specification) process:

[0032] (1) Wrap 12tex polyester cotton with single yarn and ply, then add 900 T twist;

[0033] (2) Place the twisted yarn in a place with the same temperature and humidity as the workshop, and naturally twist for more than 72 hours;

[0034] (3) Warp with batch warping machine (620 parts per shaft), and use 8 warp shafts on the sizing machine to form a weaving shaft without sizing;

[0035] (4) Apply 6 heald frames (conventional 4 pieces) to the shaft of the combined yarn, 830 healds on each heald frame, and use a reed with 144 / 10cm reed teeth to form a weaving shaft. Width 175 cm.

[0036] (5) Hang up the reeded loom, lower the back beam to the -2 position of the scale ...

Abstract

The invention discloses an air jet loom weaving method for a polyester cotton core-spun yarn fabric with a polyester filament as a core and cotton fiber wrapped outside polyester, which orderly comprises working procedures such as doubling, twist stabilization after twisting, warping and rebeaming, reeding, loom beam on-hook, adjustment of process parameters and so on. In the working procedure of batch warping, the rebeaming is performed on a sizing machine, and the sizing is not performed; during the reeding after the rebeaming, 50 to 100 percent of harness frame numbers are increased than the prior species according to the warp density; the weft-insertion time is adjusted to ensure that the weft-insertion time of previous group of auxiliary nozzles is longer than that of next group of the auxiliary nozzles and the weft-insertion time is orderly shortened in a step shape, and the entire auxiliary nozzles are synchronously closed at the same angle position. The working procedures after the adjustment effectively solve the problem that the dyeing of the polyester cotton core-spun yarn fabric has color difference after the polyester cotton core-spun yarn fabric is woven on an air jet loom, and ensure that the polyester cotton core-spun yarn fabric can be fully and normally woven on the air jet loom. The weaving efficiency can reach 96 percent, the rate of first-grade products when getting off the loom can reach more than 93 percent, woven cloth has qualified various indicators and fully satisfies the normal production of the dyeing and finishing, and no quality problem exists after the dyeing.

Description

technical field [0001] The invention belongs to a weaving process, in particular to an air-jet loom weaving method for a polyester-cotton wrapped yarn fabric. Background technique [0002] The polyester-cotton wrapping yarn with polyester filament as the core and cotton fiber wrapped around the polyester is used as warp yarn and weft yarn after doubling and twisting. Because of the polyester backbone, the fabric is crisp and stable in size At the same time, because the cotton fibers are outside, the fabric has the good wearability of pure cotton fabrics such as softness and comfort. It is a new type of clothing fabric and has a broad market prospect. [0003] Weaving fabrics with air-jet looms, after "polyester-cotton wrapped yarn inspection → doubling → twisting → (steamed yarn fixed twist) → warping in batches → sizing → reeding → hanging machine → process parameter adjustment weaving → falling cloth" After weaving by conventional techniques, although no problems can be s...
