Flannelette production has a long history in our country. In general, plain fabrics, twill fabrics, raw edging fabrics and other grey fabrics are used to move on the wire raising machine relative to the raising roller, thereby creating fluffy fluff on the surface of the fabric, thus obtaining a soft and warm feeling. Combined with bleaching, dyeing, printing, finishing and other processing techniques, fluffy products have a more beautiful appearance. Flannel is often used in winter underwear. After printing, it can also be used as a coat for women and children in spring and fall. Printed flannel is the main component of flannel production.

Printed flannel is characterized by uniform pile, clear pattern outline, smooth pile, rich depth, light color, high whiteness. In the process design, it is necessary not only to ensure the style characteristics of flannelette, but also to meet the requirements of color fastness. Flannel printing process and ordinary cotton printing process is basically the same. At present, the commonly used processes are coating processes, pull component reaction processes, and sometimes ice coating processes. In flannelette printing, anti-printing technology and anti-ink technology are also used.

Coating technique: Best used for medium, light color patterns and imitation core patterns. It can ensure smooth lines, whiteness and neat fluff, and has the advantages of short process routes, less machine occupation and various fastness. Meet the requirements. However, the friction resistance of large-area dark patterns is poor.

Active element drawing process: The process is easy to operate, the chromatogram is complete, the friction fastness is good, and the color variation is more. Therefore, the method is used for patterns with higher requirements for dye fastness. For some reactive dyes with high concentration and poor wet fastness, measures such as filling fixative fh and fixative ed can be used to improve them.

Insoluble azo dye process: Because the chromatogram of this process is incomplete and complex to operate, the ice slurry process must be used for colors such as red and dark purple, and is usually not used. In particular, the coupling rate of blue bb base and blue salt is too slow, and it is extremely sensitive to the size and dryness of the grey cloth. It is usually easy to cause color difference before and after printing, and cannot be imprinted with a rapidly coupled dye (such as red g). It can lead to incomplete hair color and poor results. When using this process, it is usually printed in conjunction with paint.

Because there is a layer of wool on the surface of the flannel, the thicker color paste is not easy to penetrate the inner layer of the wool, so the printing paste should be diluted to help the fabric evenly absorb the color paste and reduce the wool. The blurring of patterns.

The engraving depth of the flower tube should be determined according to the pattern, but due to the poor fluff and permeability of the fabric surface, the depth of the flower tube should be deeper than the ordinary plain fabric, so that the printing paste is slightly more, which is very helpful for printing. A scraper is installed on the flower tube to remove all cilia attached to the flower tube to avoid printing defects.

Flannel pattern fleece printing is a new development of flannel printing. Colored flannels printed flannel is characterized by partial flannels. According to the layout of the printing pattern, so that the background color is not velvet, but the flower is not velvet; Or the background color is velvet, but the flower is not velvet; Or part of the flower will be velvet, and some flowers will not be velvet. Patterns can be varied, with electrostatic flocking styles and three-dimensional effects.

At present, the process method of raising the pattern of wool printing is to use a certain amount of adhesive and crosslinking agent in the printing pigment paste, and cook or bake wax on the fiber surface after printing. Forming a film and seal, or adding the paint adhesive to the nitrogen dye in an insoluble manner to form a film seal, makes it difficult for the needle on the wire needle of the lint machine to penetrate the surface of the cotton yarn, resulting in no lint where the paint paste is printed and where the paint is printed without. To get flannel flannel.
