Abstract

The dyeing and finishing method of discharge print of the spun rayon fabric comprises the following steps that (1) singeing of spun rayon semi-finished products is carried out on a singeing frame, the spun rayon semi-finished products are stacked on a doffing trolley, and the stacked spun rayon semi-finished products enter an air flow machine to be further processed, and are cooled and washed with water to be used; (2) the spun rayon semi-finished products washed with the water are guided into an overflowing machine, are guided out in a cold wash mode, and enter a rope form washing machine to be processed in a soaping mode; (3) the wet spun rayon semi-finished products processed in the soaping mode are fed into a setting machine and are wound to form rolls; (4) discharge print is carried out on the set spun rayon semi-finished products with indanthrene dye, reduction washing is carried out on the spun rayon semi-finished products on the rope form washing machine, and the spun rayon semi-finished products are dried; (5) dried print fabrics are fed into the setting machine, softness arrangement is carried out on the dried print fabrics, and the width, needed by a client, of the print fabrics is well controlled. The dyeing and finishing method of discharge print of the spun rayon fabric has the advantages that the printing effect of the discharge print technology is ensured, and the number of defectives is reduced as much as possible; the spun rayon fabric has better hand feeling, perfect products are produced, and the demand of the client is met.

Description

Spun rayon piece goods pulls out the dyeing and finishing method of seal

Technical field

The present invention relates to a kind of dyeing and finishing method of fabric, particularly relate to a kind of spun rayon piece goods and pull out the dyeing and finishing method of seal.

Background technology

Existing spun rayon piece goods dyeing and finishing method, is to adopt REACTIVE DYES direct printing mostly, and little design of scattered small flowers and plants type market can be accepted, but encounters at the dark end, the colored type of light little Hua, and printing effect Fuzzy and Rough, third dimension is poor, and market reaction is very undesirable.

Summary of the invention

Object of the present invention is to change above-mentioned situation exactly, and selection intellectual circle dyestuff pulls out and prints vital staining cloth, acts in a diametrically opposite way, thereby a kind of dyeing and finishing method that allows the very strong relief spun rayon piece goods of colored type acquisition of light color flower of the dark end pull out seal is provided.

The object of the invention is to complete by following technical solution, there is following step:

1): the pre-treatment of the cotton semi-products of people: cotton people semi-products singed and banked up on cropping car on gassing frame, then the cotton semi-products inlet air flow of the people who banks up machine is further processed, finally lowering the temperature, wash stand-by;

2): the dyeing bottoming of the cotton semi-products of people: cotton the people who has washed semi-products are imported in overflow machine and cold wash derivation, enter rope form rinsing machine and soap;

3): the sizing of the cotton semi-products of people: setting machine on the cotton semi-products tide of the people cloth after soaping, roll the reservehao S that concentration is 20g/l, clot, and to control temperature be 160 ℃, the speed of a motor vehicle is 60m/min;

4): the stamp of the cotton semi-products of people: adopt intellectual circle's dyestuff to pull out seal cotton stereotyped people semi-products, dropping into temperature is that the rapid steamer gas that 102 ℃, steam pressure are 1.5kg steams 15 minutes, after in rope form rinsing machine, to add concentration be that the Boratex of 5g/l reduces washing, dry;

5): the rear arrangement of printed spun rayon sheeting: on the calico of having dried, setting machine carries out soft finish, beats overfeeding, temperature is 160 ℃, speed of a motor vehicle 50m/min, the door width that the client that simultaneously controls well is required.

As preferably, on described gassing frame, the mode of singing is a positive and a negative, gassing frame speed of a motor vehicle 100m/min; In gassing frame hopper, roll enzyme, adding concentration is the refining agent of 4g/l, the desizing agent that concentration is 2g/l, controls pick-up rate 70%, and banks up 2 hours at cropping car.

As preferably, the described cotton semi-products inlet air flow of the people who banks up machine is further processed and is added concentration to be desizing agent, bleeding agent and the refining agent of 4g/l, and controlling water temperature is 90 ℃, 30 minutes time.

As preferably, in described overflow machine, first noting concentration is the levelling agent that adds of 2g/l, and moves 5 minutes; The dye liquor that reinjects, moves 5 minutes; Then the glauber salt that implantation concentration is 60g/l, moves 10 minutes; Be warming up to 60 ℃, the soda ash that implantation concentration is 30g/l, moves 15 minutes, is incubated 40 minutes.

Beneficial effect of the present invention is: guarantee to pull out the printing effect that prints technique, reduce as much as possible defective product; Award the better feel of spun rayon piece goods, produce perfect product, meet client's demand.

The specific embodiment

The present invention is done to detailed introduction below: the present invention has following step:

1): the pre-treatment of the cotton semi-products of people: cotton people semi-products are singed on gassing frame, and the mode of singing is a positive and a negative, gassing frame speed of a motor vehicle 100m/min; In gassing frame hopper, rolling enzyme (development of evil in febrile disease CL-88G), adding concentration is the refining agent (dolantin DM-1239) of 4g/l, desizing agent, the control pick-up rate 70% that concentration is 2g/l, and banks up 2 hours at cropping car; Then desizing agent, bleeding agent and the refining agent that concentration is 4g/l further processed and added to the cotton semi-products inlet air flow of the people who banks up machine, controlling water temperature is 90 ℃, 30 minutes time, finally lowers the temperature, washes stand-by; This object is the contained slurry impurity of cotton people semi-products to process clean, to facilitate dyeing.

2): the dyeing bottoming of the cotton semi-products of people: by the people cotton semi-products importing overflow machine of wash, that first notes concentration and be 2g/l adds levelling agent (development of evil in febrile disease TF-210), moves 5 minutes; The dye liquor that reinjects, moves 5 minutes; Then the glauber salt that implantation concentration is 60g/l, moves 10 minutes; Be warming up to 60 ℃, the soda ash that implantation concentration is 30g/l, moves 15 minutes, is incubated 40 minutes, and last cold wash is derived, and enters rope form rinsing machine and soaps; This object is that the auxiliary agent of all injections strictly controls consumption and the speed that adds well, strictly controls required temperature and time well, with guarantee background color evenly, selected dyestuff is necessary for activity can discharge material.

3): the sizing of the cotton semi-products of people: setting machine on the cotton semi-products tide of the people cloth after soaping, roll reservehao S clot that concentration is 20g/l, temperature is now 160 ℃, the speed of a motor vehicle is 60m/min; Facilitate carrying out smoothly of printing technology.

4): the stamp of the cotton semi-products of people: adopt intellectual circle's dyestuff to pull out seal cotton stereotyped people semi-products, dropping into temperature is that the rapid steamer gas that 102 ℃, steam pressure are 1.5kg steams 15 minutes, after in rope form rinsing machine, to add concentration be that the Boratex of 5g/l reduces washing, dry; The printing effect that prints technique is pulled out in assurance, reduces as much as possible defective product.

Be understandable that, for a person skilled in the art, technical scheme of the present invention and inventive concept be equal to replacement or change the protection domain that all should belong to the appended claim of the present invention.
