Embodiment 1

[0016] A production process of a memory fabric, which uses PPT silk as a raw material, and is produced through the steps of warping, shrinking, sizing, paralleling, splitting, drafting, weaving and desizing. The specific steps are as follows:

[0017] The first step, warping: warp the PTT silk in batches, wind it into a PTT silk pulp shaft, the warping speed is 220 m / min, and the hardness of the pulp shaft is 70%; The pressure is 0.15Mpa;

[0018] The second step, zooming: store the paddle shaft in an air-conditioned cold room, and zoom in and out for 40 hours;

[0019] The third step, sizing yarn: the PTT yarn after warping is passed through the size tank to soak the slurry, the slurry concentration is 10%, the temperature is 41°C, and the sizing rate is 5%; then it is dried in a drying room to make PTT coated with a size film Shaft, drying room temperature is 120°C, PTT shaft hardness is 70%; sizing and drying continuous processing speed is 240 m / min, PTT wire elongation is...

Embodiment 2

[0026] A production process of a memory fabric, which uses PPT silk as a raw material, and is produced through the steps of warping, shrinking, sizing, paralleling, splitting, drafting, weaving and desizing. The specific steps are as follows:

[0027] The first step, warping: PTT silk is warped in batches, wound into a PTT silk slurry shaft, the warping speed is 340 m / min, and the hardness of the slurry shaft is 76%; The pressure is 0.25Mpa;

[0028] The second step, zooming: store the paddle shaft in an air-conditioned cold room, and zoom in and out for 50 hours;

[0029] The third step, sizing yarn: the PTT yarn after warping is soaked in the slurry through the size tank, the slurry concentration is 16%, the temperature is 48°C, and the sizing rate is 7%; then it is dried in a drying room to make PTT coated with a size film Shaft, drying room temperature 128°C, PTT shaft hardness 78%; sizing and drying continuous processing speed 270 m / min, PTT wire elongation controlled to...

Embodiment 3

[0036] A production process of a memory fabric, which uses PPT silk as a raw material, and is produced through the steps of warping, shrinking, sizing, paralleling, splitting, drafting, weaving and desizing. The specific steps are as follows:

[0037] The first step, warping: the PTT silk is warped in batches, wound into a PTT silk slurry shaft, the warping speed is 260 m / min, and the hardness of the slurry shaft is 74%; The pressure is 0.2Mpa;

[0038] The second step, zooming: store the paddle shaft in an air-conditioned cold room, and zoom in and out for 45 hours;

[0039] The third step, sizing yarn: the PTT yarn after the warping is passed through the size tank to pad the slurry, the slurry concentration is 13%, the temperature is 44°C, and the sizing rate is 6%; then it is dried in a drying room to make PTT coated with a size film Shaft, drying room temperature is 124°C, PTT shaft hardness is 74%; sizing and drying continuous processing speed is 250 m / min, PTT wire elon...

Abstract

The invention discloses a process for producing memory fabrics. The memory fabrics are made of PPT threads. The process includes steps of warping, scaling, thread pulping, beaming, leasing, drafting, weaving and desizing. The process for producing the memory fabrics has the advantage of complete non-ironing effects.
