Abstract

A codyebath process for protein fiber and PTT fiber is characteristic of that firstly the disperse dye is used to dye PTT fiber and added with protein fiber protectant to reduce the damage to protein fiber, then cleaning by additive, fully removing loose color to keep PTT fiber fastness, then added with protein fiber adoptive dye, through cleaning by ammonia and fixing by color fixatives to keep the fastness of protein fiber.

Description

A kind of azelon and ptt fiber co-bathing dyeing technology

Technical field

The present invention relates to a kind of azelon and chemical fibre PTT co-bathing dyeing technology, belong to textile fabric dyeing processing technique field.

Background technology

Ptt fiber is that the employing main component is the chemical fibre that propane class organic compound and certain acid are polymerized, its chemical name is the polypropylene terephthalate, trade name is the new product in the polyester family SOLO, has the good characteristic of terylene and polyamide fibre concurrently.Its main feature is a soft hand feeling, and comfortable flexibility and low temperature dyeing, and do not influence its premium properties with azelon (as goat cashmere, wool etc.) blending make product have brand-new sensation, helps developing low-cost, superior new product.Because azelon and PTT are two kinds of diverse fibers, the former belongs to natural protein fiber, it is a kind of hydrophilic fibre, and PTT belongs to chemical fibre, it is a kind of hydrophobic fibre, therefore, what they were selected is two kinds of diverse dyestuffs, azelon adopts hydrophilic dye (comprising ACID DYES, REACTIVE DYES, premetallized dye) dyeing, and PTT employing hydrophobic dye is disperse dyeing, select wherein any one dyeing for use for blend fibre, its result can only be the pattern effect.

Summary of the invention

At above-mentioned technological difficulties, invent that a kind of can low temperature to reach with the colouring method of bathing again be the key that this kind blend fibre carries out the product deep processing.By further investigation, sum up the co-bathing dyeing technology of a cover goat cashmere/PTT blend fibre, for necessary condition has been created in the industrialization of this product to aforementioned two kinds of fibers.

The present invention is the technology of a kind of azelon and ptt fiber co-bathing dyeing, it is characterized in that at first adopting DISPERSE DYES dyeable PTT fiber to add azelon protective agent protected protein fiber simultaneously, reduction is to the damage of azelon, clean by aids reduction then, fully remove loose colour, guarantee the COLOR FASTNESS of ptt fiber; Next afterwards by ammoniacal liquor cleaning, color-fixing agent fixation, guarantees the COLOR FASTNESS of azelon dying azelon with adding the suitable dyestuff of azelon in bathing.

Technique effect of the present invention: the present invention had both solved the co-bathing dyeing of two kinds of heterogeneity fibers, had kept two kinds of fibers style characteristic separately again.

Dyeing theory of the present invention is:

The first step: adopt DISPERSE DYES elder generation dyeable PTT fiber, add azelon protective agent protected protein fiber simultaneously, reduce damage, clean by aids reduction then, fully remove loose colour, guarantee the dyefastness of ptt fiber to azelon.

Second step: add azelon suitable dyes (comprising ACID DYES, REACTIVE DYES, premetallized dye) after stain azelon in bathing together, the dyeing back guarantees the COLOR FASTNESS of azelon by ammoniacal liquor cleaning, color-fixing agent fixation.

The 3rd step: blend fibre is carried out soft treatment, guarantee its soft hand feeling, for the spinning of back road, the weaving process of this product creates conditions.
