Abstract
The invention discloses a pretreatment process of cotton fabrics. The pretreatment process comprises the following steps of: (1) desizing treatment: adding amylase to the primary bath lotion and adding in the fabrics, increasing the temperature to the range of 62-68 DEG C, preserving heat for 62-68 minutes, and then discharging the primary bath lotion and then adding in the secondary bath lotion; (2) primary enzyme treatment: adding pectinase to the secondary bath lotion, keeping the temperature to the range of 58-62 DEG C, running for 35-45 minutes, and then discharging the secondary bath lotion and then adding in the third bath lotion; and (3) second enzyme treatment: adding cellulase to the third bath lotion, keeping the temperature to the range of 50-55 DEG C, running for 55-65 minutes, and then discharging the third bath lotion. With the adoption of the method, the process provided by the invention is green and environment-friendly, capable of saving the process cost and also capable of improving the stability and the uniformity of the treatment effect while improving the wearability of the fabrics.
Description
Technical field
The present invention relates to the fabric process field, particularly relate to a kind of pre-treatment process of COTTON FABRIC.
Background technology
Pure cotton fabric is subjected to consumer's favor deeply with its distinctive moisture absorption, the characteristic such as ventilative, warming.But, since the accompaniment of cotton fiber itself and in the cotton fiber spinning weaving process additional impurity, affected the wearability of COTTON FABRIC.For example: the microfiber of fabric face makes outward appearance coarse, and lines is unclear, and after clothes was worn a period of time, the microfiber of fabric face can form bead, affected aesthetic feeling and comfortableness.Therefore, need to carry out destarch to fabric and process, make more thorough that slurry on the fabric and impurity all removes.
At present, to the pre-treatment of COTTON FABRIC, generally adopt alkali treatment.But its process route is long, easily produces flaw, and it is well-pressed to affect product, and needs to consume a large amount of water and chemical substance, and reaction temperature is high, can cause disappearing of fabric damage and color, and the waste liquid that discharges has very large pollution to environment.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of pre-treatment process of COTTON FABRIC, and when improving wearability of fabric, environmental protection can be saved process costs, raising effect stability and treatment effect uniformity.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of pre-treatment process of COTTON FABRIC is provided, may further comprise the steps:
1) destarch is processed: will add amylase in the first body lotion, and add fabric, temperature rises to 62-68 ℃, is incubated 62-68 minute, then discharges the first body lotion, adds the second body lotion;
2) enzyme is processed for the first time: add pectase in the second body lotion, keep 58-62 ℃ of temperature, move 35-45 minute, then discharge the second body lotion, add the 3rd road body lotion;
3) enzyme is processed for the second time: add cellulase in the 3rd road body lotion, keep 50-55 ℃ of temperature, move 55-65 minute, then discharge the 3rd road body lotion.
In a preferred embodiment of the present invention, diastatic addition is 1-2g/L in the described first body lotion, and the pH value of body lotion is 6.5-7.5.
In a preferred embodiment of the present invention, the pectase that adds in the described second body lotion is alkaline pectase, and addition is 0.1-0.3 g/L, and the pH value of body lotion is 9-10.
In a preferred embodiment of the present invention, the addition of described the 3rd road body lotion cellulase is 1-2 g/L, and the pH value of body lotion is 5-6.
The invention has the beneficial effects as follows: after the amylase destarch is processed, pass through alkaline pectase-cellulase refining/biopolishing two-step process, need not to add activating agent can make finishing effect reach the concise effect of conventional base, when improving wearability of fabric, environmental protection, can save process costs, raising effect stability and treatment effect uniformity.
The specific embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
The embodiment of the invention comprises:
A kind of pre-treatment process of COTTON FABRIC may further comprise the steps:
1) destarch is processed: will add amylase in the first body lotion, and the adding fabric, temperature rises to 62-68 ℃, is incubated 62-68 minute, be preferably 65 ℃ of insulations 65 minutes, then discharge the first body lotion, add the second body lotion, wherein, described diastatic addition is 1-2g/L, the pH value of body lotion is controlled between the 6.5-7.5, is preferably 7, removes slurry and natural impurity on the fabric;
2) enzyme is processed for the first time: add pectase in the second body lotion, keep 58-62 ℃ of temperature, move 35-45 minute, be preferably 60 ℃ of insulations 40 minutes, then discharge the second body lotion, add the 3rd road body lotion, wherein, described pectase is alkaline pectase, addition is 0.1-0.3 g/L, and the pH value of body lotion is controlled between the 9-10, is preferably 9.5, remove the part hydrophobic substance on cotton fiber surface in the fabric, the part cellulose is exposed;
3) enzyme is processed for the second time: add cellulase in the 3rd road body lotion, keep 50-55 ℃ of temperature, move 55-65 minute, be preferably 50 ℃ of insulations 60 minutes, then discharge the 3rd road body lotion, wherein, the addition of described cellulase is 1-2 g/L, and the pH value of body lotion is controlled between the 5-6, be preferably 5.5, by cellulosic hydrolysis is further removed the hydrophobic substance on cotton fiber surface in the fabric, thereby reach concise purpose, cellulase is processed the function that has again polishing concurrently simultaneously.
The present invention has disclosed a kind of pre-treatment process of COTTON FABRIC, after processing, the amylase destarch passes through alkaline pectase-cellulase refining/biopolishing two-step process, need not to add activating agent can make finishing effect reach the concise effect of conventional base, when improving wearability of fabric, environmental protection, can save process costs, raising effect stability and treatment effect uniformity.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
