Problems solved by technology

[0004] Conventional polyester 167dtex / 288fDTY is used to produce flannel. The fabric weaves has poor bulkiness, poor softness, easy to fall or stick to wool, and the woven product is easy to shed, which cannot meet customer requirements.
The cashmere fabrics on the market can meet people's requirements in terms of comfort, feel, and visual or tactile effects, but they have not been widely used due to their limited resources and high prices.

Embodiment Construction

[0012] The present invention is further described below in conjunction with embodiment:

[0013] Ultra-fine porous polyester special-shaped DTY, the process flow is: POY raw yarn → pre-netting → first feeding roller → first deformation heating box → cooling plate → false twister → second feeding roller → middle network (optional) → The second heating box→the third feeding roller→oiling roller→DTY winding and forming.

[0014] Among them, the speed of the first wire feeding roller is 400m / min~435m / min, the speed of the second feeding roller is 660m / min~700m / min, the speed of the third feeding roller is 628m / min~670m / min, stretching The multiple is 1.610~1.650, the deformation temperature of the first deformation hot box is 183°C-188°C, the setting temperature of the second hot box is 170°C-180°C; the friction disc of the false twister is a 1-4-1 disc combination, D / The Y ratio is 1.55-1.63 and the setting overfeeding rate in the winding forming process is 4.25-4.90 (the third...

Abstract

The invention discloses a superfine porous dacron irregular-shaped draw textured yarn (DTY) production process which includes polyester pre-oriented yarn (POY) protofilament, a pre-network, a first yarn feeding roller, a first texturing heater, a cooling plate, a false twister, a second yarn feeding roller, a second auxiliary roller, a second heat box, a third yarn feeding roller, an oil applying rod and DTY winding molding. The second yarn feeding roller speed is 660m / min-700m / min, and drawing multiple of the second yarn feeding roller is 1.610-1.650. Deforming temperature of the first texturing heater is 183 DEG C-188 DEG C, and sizing temperature of the second heat box is 170 DEG C-180 DEG C. A friction disc of the false twister is 1-4-1 disc combination, and D / Y ratio is 1.55-1.63. Sizing overfeeding rate is 4.25-4.90, winding overfeeding rate is 5.00-5.35, and overfeeding rate of the second auxiliary roller is 3.00-3.50. Flannel fabric produced through the process has the performance of rigidity, glittering, fluffiness, pilling resistance, staining resistance and the like.

Description

technical field [0001] The invention relates to the field of textile fabric production, in particular to a production process of ultra-fine porous polyester special-shaped DTY. Background technique [0002] With the improvement of social and economic development and people's living standards, people's requirements for home furnishing design materials and clothing materials are not limited to wearable and usable, but more about their comfort, hand feel and whether they have Better visual or tactile effects. [0003] Coral fleece and flannel are currently commonly used home textile fabrics, especially flannel. The plush is relatively fine and dense, the fabric is good, and the warmth retention is good, which meets people's pursuit of product quality. Polyester DTY is used as the raw material for the production of flannel, and its quality directly affects the quality of the flannel fabric. [0004] Conventional polyester 167dtex / 288fDTY is used to produce flannel. The woven f...
