Hotel linen: identify the causes and prevention of textile products color

1, hotel linen dyes in fabric fixation in different degree: Although the dyes in the fabric on the initial distribution is uniform, but in the fixation process. Such as conditions control improper, such as temperature, time, dye concentration, make the fabric on certain parts of the dye has not been fully fixation in treatment soap wash was removed. Resulting in color. For example, disperse dye thermosol temperature before and after both sides or inconsistent, vat dyes as part of the reduction or oxidation is not sufficient, reactive dyes steaming conditions adverse etc. will cause fabric properties before and after or about color.

2, dye in the fabric on the prior distribution is not uniform: dye before fixation, if in weaving the parts on the uneven distribution, solid color must form a color. The main reason for this phenomenon is:

(1) fabric factor: due to different fiber properties or before treatment, boiling, bleaching, silk is not uniform thoroughly, so that the dye uptake of the first half of the product is not uniform and cause the difference of dye absorption.

(2) the absorption factor; due to the mechanical structure of reason or improper operation, make the fabric in all parts of the liquid at the same rate, resulting in color. Roll pressure unevenness, adding dye unevenness will make the fabric absorbing dye unevenness.

(3) pre drying factors: in pad dyeing after pre drying, due to the inconsistency of the rate and extent of drying, causing dye has different degree of migration to make dyes in fabric are unevenly distributed.

3, dye color variation, this difference was not due to the fabric on dye distribution uneven caused。 But for some reason cause fabric shade on the part of the dye changes, generally have the following reasons:

广东快乐十分网(1) before dyeing factors: semi-finished products brightness unevenness or pH values are different, the dye is often caused by color difference.

Hotel linen Z (2) dyeing factors: such as dispersing dye thermosol temperature is too high, the shade of some dyes become wilt dark; vat dyes over reduction, the color difference.

(3) after dyeing factors: in the finishing process, such as resin finishing, high-temperature stentering and compounds on the pH value of different fabric etc。, cause color of dyes have varying degrees of change。

(4): such as soap soap is not sufficient, can make the hair color is not sufficient to light
