Description
Technical field
The present invention relates to cashmere dyeing processing technology field more particularly to a kind of cashmere pre-treatment, dyeing and method for sorting.
Background technique
Cashmere is thin and curved fiber one by one, wherein containing many air, and forms air layer, can be defendd outer
Carry out the invasion of cold air, retaining body temperature will not lower.Cashmere is thinner than wool very much, and outer scale is also finer and closely woven than wool, smooth, because
This, light-weight, soft, good toughness.It is particularly suitable for manufacturing underwear, it is light, soft, soft, sliding when wearing next to the skin, it is any as snug as a bug in a rug
Fiber is incomparable.
Dyeing process for loose wool cashmere fiber is thin, and strength is low.Under normal conditions, flock dyeing temperature is 100 DEG C or so, albumen
Peptide bond in matter molecular structure can be hydrolyzed sharply, and fibrous molecular structure is caused to change；The scale layer of fiber surface simultaneously
It wrecks, woollen and cashmere fabric hand is made to be hardened, strength is impaired, and spinnability reduces.
The present invention is directed to the special situation of cashmere, provides a kind of cashmere pre-treatment, dyeing and method for sorting.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of cashmere pre-treatment, dyeing and method for sorting.
Technical scheme is as follows:
A kind of cashmere pre-treatment, dyeing and method for sorting, comprising the following steps:

Treatment temperature is 30-35 DEG C, and the processing time is 45-60min, bath raio 1:20-30；It is dried for 25-35 DEG C after processing；
B dyeing processing:
B-1 configures dyeing liquor: adding water to configure to obtain dyeing liquor using keratinase, cassia seed, lubricant, dispersing agent；
B-2 ultrasonic treatment: cashmere fiber being dissolved in dyeing liquor, is handled rapidly, and treatment temperature is 30-50 DEG C, supersonic frequency
Rate 8-15kHz, sonication treatment time 2-3min, bath raio 1:20-30；Cashmere fiber after ultrasonic treatment is transferred quickly to
In 80-85 DEG C of enzyme deactivation pond, 8-10min is handled；
B-3 natural dye dying: cashmere fiber is dyed using natural dye and using exhaust process；
C is arranged: configuration finishing fluid, and will dyeing treated that cashmere fiber is put into finishing fluid keeps the temperature 15-25min；Use cold water
40-50 DEG C of drying after rinsing 2-3 times.
Preferably, in the step B-1, in the dyeing liquor, keratinase additive amount is 2-5U/g wool fabric
(dry weight), the additional amount of cassia seed are 1-8% o.w.f.；The additional amount of lubricant is 0.2-0.5% o.w.f.；Dispersing agent adds
Entering amount is 0.1-0.2% o.w.f..
Preferably, in the step B-1, in the dyeing liquor, the lubricant is glycerol；The dispersing agent
For polyacrylate hyper-dispersant.
Preferably, in the step B-1, the preparation method of the dyeing liquor, comprising the following steps:
Step 1: cassia seed raw material is rinsed well with clear water, it is mechanically pulverized repeatedly after drying with weight method, crosses 800 mesh
Sieve, extracting screen underflow；
Step 2: the cassia seed powder after sieving is added to the water, and dispersing agent is added, and is heated to 45-50 DEG C, carries out ultrasonic disperse,
Supersonic frequency 40-60kHz, time 5-8min；
Step 3: keratinase and lubricant is added, stirs evenly.
Preferably, in the step C, the finishing fluid is configured using alkaloid；PH value is 7.5-8.0, and temperature is
60-70℃。
The invention has the beneficial effects that: cashmere pre-treatment, dyeing and method for sorting of the invention, in traditional handicraft
Using a large amount of chemicals, not only cashmere fiber is damaged, and defect not environmentally, the present invention in using enzymatic treatment+
Cassia seed powder+ultrasonic treatment+natural dye dying mode dyes cashmere fiber, not only small to the injury of cashmere, and
And without using chemicals, (citric acid used in the present invention, glycerol, alkaloid are that biology mentions substantially in entire treatment process
Take and be prepared), safety and environmental protection.
