Problems solved by technology

[0003] Cotton flannel fabric processing has direct printing and pigment printing. The direct printing process is prone to problems such as washing and fading, and the molecular structure of dyes is easy to cause cancer; the pigment printing process (by sticking the adhesive to the surface of the fiber), Although no waste water is produced, the product feels hardened and is easy to rub and fade

Embodiment 1

[0029] A production process of cotton flannel printed fabric, comprising the steps of:

[0030] Step 1, the whole cotton 21s yarn and the carded wool yarn are subjected to acid fixing, color fixing and drying respectively to obtain the pretreated whole cotton 21s yarn and the pretreated carded wool yarn for use;

[0031] Step 2, select the pretreated cotton 21s as the warp yarn, the pretreated carded wool yarn as the weft yarn, and weave through the two-up and two-down left twill weaving method to obtain the fabric after weaving for use;

[0032] Step 3. Put the woven fabric into the printing paste for printing treatment. The temperature of the printing paste is 30°C, and the printing speed is 10m / min. Then, it is dried and steamed to fix the color. The temperature is 150°C, and the time is 12 minutes, and the printed semi-finished fabric is ready for use;

[0033] Step 4: Washing, dehydrating and drying the printed semi-finished fabric in sequence to obtain a cotton flannel ...

Abstract

The invention relates to the technical field of flannel fabric production processes, in particular to a production process of an all-cotton flannel printed fabric. The production process comprises the following steps of carrying out acid fixation, color fixation and drying on all-cotton 21s yarns and carded wool yarns to obtain pretreated all-cotton 21s yarns and pretreated carded wool yarns; performing weaving through a two-up two-down left-inclination twill weaving method to obtain a woven fabric for later use; and putting the woven fabric into printing paste for printing treatment, and then performing water washing, dewatering and drying and setting to obtain the all-cotton flannel printed fabric. The problem that in the prior art, an all-cotton flannel fabric is prone to fading is solved; the all-cotton 21s yarns and the carded wool yarns are easier to color after being pretreated, are not easy to fade after being colored, and are higher in color fastness; and a reactive printing process is used for production, and active components in the printing paste can better enter fibers, so that the color fastness is improved.

Description

technical field [0001] The invention relates to the technical field of flannel fabric production technology, in particular to a production technique of all-cotton flannel printed fabric. Background technique [0002] Flannel is a soft and suede (cotton) wool fabric woven from carded (cotton) wool yarn. The production of flannel is to dye part of the wool (or cotton fiber) first, then mix it with a part of the original color wool (or cotton fiber), mix and spin it into a mixed-color wool yarn, and weave it into a fabric through milling and napping. Most of them use twill weave, but also plain weave. In addition to all wool (or pure cotton), the raw materials used are generally wool (or pure cotton) viscose blended, and some are mixed with a small amount of nylon fiber to improve wear resistance. [0003] Cotton flannel fabric processing has direct printing and pigment printing. The direct printing process is prone to problems such as washing and fading, and the molecular st...
