Description
Technical field
The present invention relates to fabric processing technique fields, specially knitting modal fabric pressing mold xanthochromia technique resistant to high temperatures.
Background technique
Women underwear brassiere fabric is a special branch for being knitted fabric in fabric market, generally uses Modal spandex
Single jersey occupies a certain amount of share in high-end fabric market as mould cloth, the product, and product profit is higher, but quality and environmental protection
It is required that high, especially the resisting high-temperature yellowing of fabric is required high, and xanthochromia color difference requires to be greater than 3 grades before and after pressing mold.But can really it expire
The manufacturer that sufficient quality of brand name requires is seldom, and is typically all the enterprise for making high-end fabric, main cause i.e. anti-height
Temperature and pressure mould xanthochromia or exterior quality (yellowish-white segment difference) or color can not pass, therefore exploitation meets the resistance to compression die face material of customer requirement
Technique has vast market prospect.
To solve the above-mentioned problems, this case is given birth to therefrom.
Summary of the invention
(1) the technical issues of solving
It is an object of the present invention to be knitted Modal spandex undershirt cloth by using the good process of assay optimization, fabric is made to exist
The xanthochromia that fabric can be effectively resisted under high temperature compression molding conditions (195 DEG C handle 50 seconds), make before and after pressing mold discoloration control one compared with
Small range (color difference >=3 grade).
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: knitting modal fabric pressing mold resistant to high temperatures is yellow
Exchange work skill, including determine embryo-machine cylinder pre-treatment-post-processing-system it is soft-cloth outputting-dewatered drying-final finishing-inspection-finished product technique stream
Journey；
1) in pre-treatment process, bleeding agent, degreaser, scouring enzyme, H2O2 are put into machine cylinder, and successively perform the following operation:
25-35min is reacted at a temperature of 90-100 DEG C, drain adds HAC after washing hot water 10min, reacts at a temperature of 40-60 DEG C
5-15 minutes, and carry out washing hot water 10min again, realize cloth cover radial direction capillary effect >=8cm；
2) final finishing process is the fabric by dewatered drying, is handled using padding method completion, padding method process are as follows: fabric-leaching
Roll-dry-bake-thoroughly cold it is thoroughly cold；
Further it is provided that
Pad process be added anti-yellowing agent 2-4%(owf), citric acid 0.05-0.1%(owf)；One immersing and rolling, realization pick-up >=
80%；It preferably, further include dyeing flow between the pre-treatment of machine cylinder and post-processing, wherein machine cylinder pre-treatment-dyeing-post-processing-system
Soft technology process carries out in the same machine cylinder, and dyeing flow specifically sees that technique is selected, and is specially added before cylinder out
Citric acid concentration 0.3g/L, and run 15min.Citric acid is for adjusting cloth cover pH value, so that pH value control is between 5-6.
Preferably, the content of each component is respectively bleeding agent in pre-treatment process: 0.5-2%(owf), degreaser: 0.5-
2%(owf), scouring enzyme: 1-2%(owf), H2O2:5-8%(owf), solution bath ratio is 1:5-10, is reacted at a temperature of 90-100 DEG C
25-35min, drain adds HAC 0.5-1%(owf after washing hot water 10min), 5-15 points are reacted at a temperature of 40-60 DEG C
Clock, and carry out washing hot water 10min drain again, finally enter water and citric acid 0.3g/L be added to run 15min cloth outputting, wherein material
The sequence of addition be first plus bleeding agent, then plus degreaser, then plus refining enzyme, finally plus hydrogen peroxide, deoil clean wash water need it is thorough
It cleans up.
Preferably, plastic flow journey processed is using the smallest nonionic consistent lubricant of discoloration or the dedicated consistent lubricant of bleaching.
Preferably, it needs successively to dry process afterwards according to being first dehydrated after cloth outputting, and controls temperature at 100-130 DEG C.
Preferably, the drying course after the completion of padding controls temperature≤130 DEG C；Baking process temperature is controlled in 150-180
DEG C, speed of service 20-25m/min.
(3) beneficial effect
After adopting the above technical scheme, compared with prior art, the present invention having following advantages:
1. the optimization of flow process is so that fabric discoloration before and after pressing mold is controlled in a smaller range, color difference >=3 grade can
Effectively there is a situation where xanthochromias for control fabric.
2. the fabric appearance and interior quality fabric of process flow production are good, cloth is soft, meets client and wants
It asks, meets OECO-TEX ecological, environmental protective requirement.
Specific embodiment
The process flow of the present embodiment be determine embryo-machine cylinder pre-treatment-post-processing-system it is soft-cloth outputting-dewatered drying-final finishing-
Inspection-finished product.In addition to the pre-treatment of machine cylinder and final finishing are improvement in this process flow, remaining process is conventional known skill
Art.
Wherein using the smallest nonionic consistent lubricant of discoloration or the dedicated consistent lubricant of bleaching in plastic flow journey processed；Needed after cloth outputting successively according to
It is first dehydrated and dries process afterwards, and control temperature at 100-130 DEG C.Drying course after the completion of padding controls 100-130 DEG C of temperature；
The control of baking process temperature is best, reaction speed 20-25m/min at 170 DEG C.
Post-processing process is mainly wash water process.Saturating cold thoroughly cold process mainly for allowing body to fill after cropping of being formed
Divide cooling, it is ensured that Yellowing does not occur in cloth.
The solution that wherein pretreatment process and final finishing use in the process is the aqueous solution of auxiliary agent, and cloth is not using
Dai Er spandex undershirt cloth.
