The disclosure relates to the technical field of after-finishing of textile products, and in particular relates to a delayed-cure durable press finishing technology for cotton fabrics, including the following steps: singeing, desizing, liquid ammonia finishing, mercerizing, liquid ammonia finishing and post-cure finishing. The disclosure significantly improves the stability of a delayed-cure sensitized fabric during delayed-curing, relieves the problems caused by a slow reaction in the storage process of the delayed-cure sensitized fabric, and is favorable for improving the product quality.

An automatic fabric folding device has a rotating mechanism, an automatic folding mechanism and a crease generating mechanism. The automatic folding mechanism is located below the finger cylinder on one side of the rotating mechanism, and the finger cylinder on the other side of the automatic folding mechanism is fixed with a crease generating mechanism. The two rotating cylinders are central symmetrical with the rotating arm. This accurately controls the bending and folding of the fabric sample through the automatic control technology, and realizes the automatic detection of the fabric crease recovery process. By mechanical and numerical control technology, the parts to be measured are effectively prevented from interference by human factors, and the detection accuracy is improved.

A method for evaluating crease recovery of fabrics based on power function equation. The steps are: (1) place the sample in the sample placement area; (2) pressure the overlapping part of the sample; (3) let the free part of the sample automatically restore and record the video image of the sample crease recovery by camera; (4) process the video image of the fabric crease recovery and calculating the recovery angle of each frame of video image; (5) repeat steps 1 to 4 to measure N samples of the same fabric; (6) obtain the dynamic process of fabric crease recovery angle change. This can reveal which type of fabric has better recovery property, when the existing methods have the similar results of recovery angle.

A device includes a drafting and twisting system. The drafting and twisting system includes a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. Blending proportion and linear densities of the four ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control a linear density change, but also accurately control color change of the yarn. Further, rotation rate of the middle roller is constant, ensuring a reproducibility of patterns and colors of the yarn with changing linear density.

The present invention relates to a method for drafting spun yarns in three stages. The method comprises drafting fiber strips to obtain fiber strands in the first-stage draft zone, drafting fiber strands to obtain non-discrete fiber bands without twist distribution in the second-stage draft zone, and drafting fiber bands to obtain twist less fiber assemblies in the third-stage draft zone. The methods optimize the maximum total draft ratio to obtain twist less fiber assemblies while maintaining evenness and required quality of resultant yarns.
