Problems solved by technology

This invention patent is suitable for the production process of high-crimp polyester low-stretch yarn with PTT performance. The PTT products produced have high defect rate, large loss of raw materials, low production efficiency of looms, improper process control, and easy to produce tension. Average, after willow blemishes, the dyeing and finishing treatment feels rough, and the memory function of the fabric is seriously damaged

Embodiment 1

[0034] (1) Warping in batches:

[0035] According to the warp density requirements of the fabric, load the corresponding number of PTT silk bobbins on the creel of the warping machine, and carry out warping in batches. The speed of the warping is set at 250 m / min. Shaft hardness control is 80%.

[0036] (2) pulp:

[0037] The PTT yarn made by warping in batches passes through the size tank to pad the slurry, the slurry concentration is 12%, the slurry temperature is set at 40°C, and then dried in the drying room to make the PTT shaft coated with the size film. The drying room temperature It is set to 130°C, and the continuous processing speed of sizing and drying is set to 230 m / min.

[0038] (3) parallel axis:

[0039] The PTT shafts obtained from the sizing yarns are put into the warp beam frame of the doubling machine, and the PTT yarns are evenly discharged into the telescopic reeds by using the method of staggering 3 reeds, the reed width is adjusted, and the warp beam...

Abstract

The invention relates to a PTT (poly(trimethylene terephthalate)) memory fabric, in particular to a PTT memory fabric production process. The production process comprises the following steps of: batch warping, starching, shaft combining, leasing, looming healding, weaving, pretreatment of dying and finishing, alkali quantity decreasing, dying, waterproof processing and thermal forming. The fabric has unique memory function and comfortable hand feel, the performance of smoothing by touching the fabric enables the product to achieve an effect of totally ironing free, and favorable draping effect and recovery capability enable the fabric to become one of fashionable functional fabrics. Fibers of the fabric are completely biodegradable under certain condition and the fabric is an environmental-protection and green product.

Description

technical field [0001] The invention relates to a PTT memory fabric, in particular to a production process of the PTT memory fabric. Background technique [0002] Chinese patent CN101220536, a kind of high-shrinkage polyester low elastic yarn with PTT performance and its production process. The present invention is realized in this way: adopting the orthogonal experimental statistical method to obtain a group or array of process parameters and related product data, from which the most reasonable process parameters and product performance indicators are obtained, and continuously optimized on this basis, thereby obtaining Process parameters described in the present invention have also produced related products simultaneously. This invention patent is suitable for the production process of high-crimp polyester low-stretch yarn with PTT performance. The PTT products produced have high defect rate, large loss of raw materials, low production efficiency of looms, improper proces...
