Description
Technical Field
The invention relates to a method for improving fluffy fabric rotary screen printing screen blocking, and belongs to the technical field of textile printing and dyeing.
Background
The fluffy fabric is soft in hand feeling due to soft hairiness, high in wearing comfort level and good in heat retention, and is particularly widely applied to the field of autumn and winter clothes. However, the processing of the printed fabric has great difficulty for the following reasons: if the fuzzing finishing is carried out after the printing, the printing is surface coloring, and internal hairiness is hooked out, so that the problems of whitish cloth cover and fuzzy pattern can be caused; if the printing processing is carried out after fluffing, the fluffs are easy to fall off and adhere to a circular screen, so that the problem of screen blocking is caused, the printing pattern is incomplete, white spots are particularly generated on large-area color blocks, and the attractiveness of the cloth cover is seriously influenced.
Disclosure of Invention
The invention aims to provide a method for improving fluffy fabric rotary screen printing blocking, which is scientific and reasonable in design, avoids the blocking problem, improves the problems of incomplete printing pattern and white spots on the cloth cover, and is beneficial to industrial application.
The method for improving the circular screen printing blocking of the fluffed fabric adopts the process of fluffing → sanding washing → pre-tentering → printing → steaming → washing to process the fabric.
The pre-stretching step process comprises the following steps: padding feed liquid → drying, wherein the feed liquid adopts acrylic acid thickening agent.
Preferably, the acrylic thickener is DIAMONTEX HD-U.
Preferably, the concentration of the feed liquid is 30-80 g/L.
Preferably, the drying temperature in the drying process is 110-130 ℃ and the time is 20-40 s.
The printing step process is to print large-area color blocks by using two circular screens, wherein the first circular screen is a solid color block, and the second circular screen is designed by adopting 50-70% gray level.
The functions of the above process flows are respectively as follows:
fluffing: endowing the surface of the fabric with uniform and dense hairiness.
Sanding and washing: and (4) washing floating hair after fluffing to prevent the subsequent printing from blocking the screen.
Pre-tentering: padding a thickening agent to adhere hairiness; adjusting the width to meet the requirements of finished products, and avoiding pattern size difference; and adjusting the weft skew to the post-washing state to prevent the pattern skew after washing.
Printing: printing the required pattern.
Washing with water: washing off the floating color, the paste and the thickening agent used for pre-stretching.
According to the process, after fluffing, part of flower hairs are washed and removed by sanding and washing; padding an acrylic thickener during pre-stentering, and adhering the flower hair to the cloth surface in advance by utilizing the characteristic of high viscosity of the acrylic thickener to prevent the flower hair from falling off during printing; and (3) printing a large-area color block by using two round screens during printing, wherein the first round screen is a real color block to ensure the integrity of the pattern, the pattern of the second round screen is 50-70% gray, and the blank of the screen after the first round screen is printed is filled.
Compared with the prior art, the invention has the following beneficial effects:
(1) the acrylic thickener adopted in the invention can not only adhere the flower hair to the cloth surface in advance to prevent the flower hair from falling off during printing, but also wash the flower hair after printing and washing, and does not influence the hair feather effect and hand feeling of the cloth surface;
(2) the second rotary screen added in the printing process is a non-solid color block, and the influence on the pattern color caused by large slurry output amount can be avoided by adopting the gray design, so that the color and the pattern control are facilitated;
(3) according to the invention, by improving the printing process, the problem of white spots caused by net blocking during circular screen printing of the fluffy fabric is solved, and the difficulties of dyeing and finishing and subsequent fabric repair are greatly reduced.
