Flannelette production process

Abstract

The invention discloses a flannelette production process, and belongs to the technical field of flannelette production, and the flannelette production process comprises the following steps: S01, needling: making polyester fibers into primary flannelette on a warp knitting machine through a needling method; s02, hanging: the primary flannelette is divided into two parts with the same area, and the two parts are hung through a cylindrical stick; s03, dyeing: pouring a liquid pigment at the junction of the two parts of the primary flannelette from top to bottom at a constant speed, so that the pigment slides down from the two sides of the primary flannelette at the same time, and after the pigment completely covers the surfaces of the two parts of the flannelette, continuously pouring the pigment for 10-15 minutes; s04, temperature regulation: dynamically regulating and controlling the temperature of the liquid pigment in the whole process of S03, and controlling the temperature range of the liquid pigment to be 20-30 DEG C, so as to obtain secondary flannelette; and S05, material soaking: soaking the lint in the pigment for 1 hour after the step S03 and the step S04 are finished. According to the process, the dyeing effect can be better, the combination degree of the pigment and the primary flannelette is higher, the dyeing time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of flannel production, in particular to a flannel production process. Background technique [0002] The fleece is made of polyester fiber and is made by acupuncture process. There are two kinds of single-sided fleece and double-sided fleece. The single-sided fleece is mainly twill, also known as serge fleece; the double-sided fleece is mainly plain weave. The flannel is soft, comfortable to wear, and has good warmth retention. It is suitable for winter underwear and pajamas. [0003] In the prior art, in the production process of flannel, the method of dyeing is usually not paid attention to. Most of the traditional methods are to put the cloth into the dye pool for dipping dyeing, but in this way, the pigment and the cloth are basically relatively static. , instead of dynamic contact, which leads to a decrease in the degree of fusion between the pigment and the cloth, which is not conducive to the combina...

Problems solved by technology

[0003] In the prior art, in the production process of flannelette, the dyeing method is usually not paid attention to. Most of the traditional methods are to put the cloth into the dye pool for impregnation dyeing, but in this way of dyeing, the pigment and the cloth are basically relatively static. , instead of dynamic contact, resulting in a decrease in the degree of fusion between the pigment and the fabric, which is not conducive to the combination of the pigment and the fabric, resulting in a mediocre dyeing effect. Therefore, it is necessary to immerse the fabric in the pigment for a long time to make up for this defect, which reduces production efficiency.
