Abstract
The invention discloses a mercerizing and dyeing process and method for warps of jean. The process is characterized by comprising the steps of: soaking with caustic soda with concentration with 25 Baume degrees and ventilating; then washing twice by hot water at 60 DEG C; then neutralizing to pH value of 4.5-6 (preferably 5) by glacial acetic acid; and then dyeing and carrying out the following steps. According to the mercerizing and dyeing process and method for warps of jean provided by the invention, the color fastness to rubbing and color fastness of fabric can be remarkably improved.
Description
Technical field:
The invention relates to a kind of technology and method of denim warp thread mercerising dyeing.
Background technology:
American-European countries has many families to use the cloth sofa of light color, because the sulphur black lining of common decoration method dyeing, the look crock fastness is too low to be prone to cause staining, so high-grade jeans seldom use, can not meet the need of market.Former common decoration method dyeing is simple: dyeing-washing-oven dry-starching-oven dry-coiling, this method effect is undesirable: cost height, COLOR FASTNESS poor (fading easily), scrappage height.
Summary of the invention:
The technical problem that the invention will solve provides technology and the method that a kind of denim warp thread mercerising that can obviously improve the look crock fastness of fabric dyes.
The technical scheme of the invention is: the technology and the method for the dyeing of denim warp thread mercerising is characterized in that technological process is:
It is ventilative to use concentration to be that the caustic soda of 25 Baume degrees soaks the back, uses 60 degrees centigrade hot water wash two roads again, and adding glacial acetic acid then, to be neutralized to pH value be 4.5-6 (being preferably 5), dyes-wash-dry-starching-oven dry-coiling again.
Principle: cotton yarn generates alkali cellulose under the caustic soda effect; And making fiber that irreversible violent swelling take place, its principle is that the sodium ion volume is little, still can not get into the amorphous region of fiber; The crystal region of infiltrated fiber that can also part; Sodium ion has very thick hydrated sheath, brings a large amount of moisture content simultaneously into, thereby causes the violent swelling of fiber.Because the violent swelling of fiber makes the cell of irregular arrangement originally clocklike arrange and makes the cell crystal of kidney shape change into circle; Thereby the dye uptake of fiber is increased; Dye-uptake increases, simultaneously because the cell that has the rule rate to arrange has produced certain refractivity; Make jean produce soyeux gloss from face, promote the class of product.
Advantage of the present invention: the product of the Dyeing Process of Cotton Yarn behind mercerising, lovely luster has soyeux gloss.Its maximum characteristics are obviously to improve look crock fastness, the staining fastness of fabric, produced beyond thought effect, have solved people and have thirsted for the technical barrier that solves always, meet the variation of modern jeans method for washing.Won the very intimate of client after the product test manufacture, will significantly improve economic benefit in commercial achieving success.
The specific embodiment
The technology and the method for the dyeing of denim warp thread mercerising; It is characterized in that, may further comprise the steps: use concentration is ventilative after the caustic soda of 25 Baume degrees soaks, and uses 60 degrees centigrade hot water wash two roads again; Adding glacial acetic acid then, to be neutralized to pH value be 4.5-6 (being preferably 5), dyes and later operation again.The invention can obviously improve look crock fastness, the staining fastness of fabric.
