Description
Technical field
The present invention relates to the degumming tech of silk fabric, in particular to a kind of Degumming method of silk knitted fabric.
Technical background
Silk knitted fabric is the fabric that silk is bent lopping and mutually string set using knitting needle and is formed, than conventional woven silk
Silk shell fabric has better flexibility and wrinkle resistance, is welcomed by consumers.In silk knitted fabric, although also there is the small part to be
It is ripe to knit a knitted fabric (color-woven fabric), but the overwhelming majority is knitting green compact.It is more than due to being typically contained in the raw silk knitted fabric knitted
20% or more silk gum, therefore, it is necessary to carry out degumming to silk knitted fabric.Currently, the degumming of common silk knitted fabric, main to use
Alkali degumming, the degumming of soap alkali, enzymatic degumming method and organic acid Degumming method.These methods all achieve certain effect, but there is also
Certain drawbacks.Alkali degumming and soap alkali method for degumming are that most wide method is used in factory.But alkali degumming and soap alkali method for degumming one
There are degumming liquids to reuse for aspect, influences environment；On the other hand, it since silk is not alkaline-resisting, is easy to generate silk fiber
Certain damage；Moreover, because containing a large amount of inorganic ions and chemical group in degumming liquid, it is difficult to carry out recycling benefit to silk gum
With.In addition, the silk fiber for constituting raw knitting needle fabric does not have the twist or the twist lower compared with woven silk fabrics, therefore, alkali is de-
In glue or soap alkali scouring processes, the silk fiber in silk knitted fabric is easier to be damaged than woven fabric, to influence silk needle
The mode of appearance and mechanical property of fabric.Although enzymatic degumming method can play a certain protective role silk fiber,
On the one hand it is suitble to the kind of the enzyme of natural silk degumming seldom, and enzyme has a specificity, the silk fiber of different cultivars is with same
Enzyme, there are the differences of degumming effect；On the other hand, enzyme is at high cost, is also easy to inactivate, application range is restricted.Organic acid
Degumming includes mainly citric acid degumming and tartaric acid degumming etc., although organic acid degumming can protect the mechanical property of fibroin not
It is impacted, but since organic acid is easy to generate complex reaction with fibroin, certain influence is often generated to the performance of ontology, is made
Cheng Houdao dyeing quality decline etc., so that there are certain popularization difficulty.Some scholars study with superheated steam to silk fiber
Degumming is carried out, but there is the problems such as strength declines.
Summary of the invention
The purpose of the present invention is to solve problem of the prior art, provide efficient one kind, environmental protection, to silk knitted fabric
The small Degumming method of Effect on Mechanical Properties.
In order to achieve the above object, technical solution of the invention is as follows:
A kind of Degumming method of silk knitted fabric comprising the steps of:
(1) pre-preg:
Under room temperature, silk knitted fabric is soaked in soak immersion treatment 40-180 minutes completely, the soak is dense
Degree is the hydrochloric acid solution of 0.05-0.15mol/L.
(2) wet-hot steam degumming:
Silk knitted fabric after step 1 pre-preg is placed in the wet-hot steam of 0.12-0.15MPa 15-60 minutes, so
Afterwards again with heat water-spraying 5-10 minutes of 80 DEG C；It is molten to place into the hydrochloric acid that temperature is 90-95 DEG C, concentration is 0.01-0.05mol/L
It is impregnated 30-90 minutes in liquid, bath raio 1:30-50；
(3) it cleans:
Silk knitted fabric obtained in step (2) is put into the water that temperature is 50-70 DEG C and is cleaned by ultrasonic 20-30 minutes,
It is cleaned again with normal-temperature water to pH > 6.5, the silk knitted fabric after obtaining degumming.
Further, in the step (3), it is cleaned by ultrasonic 2 times with 50-70 DEG C of water, wherein cleaning for the first time is with temperature
Degree cleans for 60-70 DEG C of water, ultrasonic frequency 80-100KHz, and ultrasonic time is 10-15 minutes；Second of cleaning is use
50-60 DEG C of temperature of water cleaning, ultrasonic frequency 80-100KHz, ultrasonic time are 10-15 minutes.
The beneficial effects of the present invention are:
Auxiliary agent content used in the present invention is few, and impregnation liquid secondary can use, and the influence to environment is small；
Hydrochloric acid used in the present invention is inorganic acid, does not generate complex reaction with fibroin, is not influenced on subsequent dyeing；
Concentration of hydrochloric acid used in the present invention is lower, will not generate degradation to fibroin, and because maceration extract is acidity, to silk needle
The mechanical property of fabric will not generate apparent negative effect, and obtained knitted surfaces are smooth, groove is less, silk gum removal efficiency
Height, whiteness, glossiness are good；
Detailed description of the invention
Fig. 1 is degumming device schematic diagram；
Fig. 2 is the configuration of surface of untreated fabric；
Fig. 3 is the configuration of surface of silk fiber of the fabric fibre after the method for the present invention degumming.
Specific embodiment
Hydrochloric acid is inorganic acid, does not generate complex reaction with fibroin, does not influence the subsequent dyeing process of silk fabrics；Simultaneously because
Compared with the water of liquid, stream molecule reunion probability is low, is easily accessible inside silk gum, can make degumming more evenly.Therefore, this hair
The silk fabrics surface that the bright common degumming of method combination inorganic acid combination steam obtains is smooth, groove is less, and silk gum removal efficiency is high,
Whiteness, glossiness are good；
The present invention will be further explained below with reference to the attached drawings and specific examples.
Embodiment 1

(1) pre-preg
After the silk knitted fabric for weighing a certain amount, it is immersed into the maceration extract that concentration of hydrochloric acid is 0.12mol/L, dipping
180 minutes.
(2) wet-hot steam degumming
The fabric after impregnation is taken out, is put into the fabric holding chamber of Fig. 1, after closed, being passed through pressure is
The damp and hot water vapour of 0.15MPa, after sixty minutes, with heat water-spraying 5 minutes of 80 degree；Placing into concentration of hydrochloric acid is 0.01mol/L,
Temperature is 90-95 DEG C, is handled 90 minutes in the dilute hydrochloric acid solution that bath raio is 1:50；
(3) it cleans
Fabric Jing Guo damp and hot steam treatment is taken out, being put into water temperature is that progress is clear for the first time in 60 degree of supersonic cleaning machines
It washes, after cleaning 15 minutes, carries out second with 50 degree of water and be cleaned by ultrasonic, clean 10 minutes.Then, it is cleaned with normal-temperature water to pH
>6.6.The silk knitted fabric after degumming is obtained after being routinely formed.
(4) bursting strength of knitted fabric is tested according to GB/T 19976 by weight method measurement degumming rate.
As a comparison, degumming is carried out to the silk knitting fabric of same specification with conventional alkali degumming and soap alkali method for degumming.
As a result such as table 1:
Table 1: degumming rate and bursting strength
