PTT (poly(trimethylene terephthalate)) memory fabric production process

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...
