Abstract
The invention discloses a preparation method of colored cotton fiber. The preparation method includes the following steps of enzymatically de-sizing, namely de-sizing colored cotton fiber by amylase; softening by silicone oil, namely softening the colored cotton fiber by silicone oil; burning off nap, namely getting the colored cotton fiber through a fire spraying port to burn off fine nap on the surface of the colored cotton fiber; and mercerizing, namely allowing for gap swelling and tissue swelling of molecular links of the colored cotton fiber by concentrated alkali. Treating speed of the colored cotton fiber is increased and damage of the fiber is reduced by enzymatically de-sizing. In follow-up treatment, the fiber is softened, the nap is burned off, and accordingly comfort for wearing the fiber is increased. Appearance of the fiber can be improved by mercerizing.
Description
Technical field
The present invention relates to fibre manufacturing technology, relate in particular to a kind of preparation method of color cotton fiber.
Background technology
Because the constraint that overall view is read, the underwear industry of China is started late, and in the traditional concept, underwear is the dress ornament that can not be seen by the people.After the nineties in 20th century, along with expanding economy, people are to the understanding of dress ornament and require to improve day by day, and the understanding of underwear has also been had new change.When standing in great numbers the underwear billboard in the street, just walking outwards wearing with regard to showing underwear significantly, this has been irreversible development trend.It with rich culture contain, exquisite technology, being developed by general furnishings becomes the dress ornament elaboration.
Therefore the direct contacting skin of underwear has the higher snugness of fit and the requirement of health.Color cotton is a kind of raw cotton fiber, has that color and luster is soft, quality is soft, the characteristics of no chemical harmful substance.Be suitable for making underskirt.Color cotton fiber present faintly acid, coincide naturally with people's skin faintly acid, therefore, human body skin is had the natural health skin-protecting function, often dress can be played effect antipruritic, affine skin.Natural Colored Cotton Textile is respond well to shielding of ultraviolet radiation.The ultraviolet ray transmissivity of natural color cotton cloth significantly is lower than the white cotton cloth, especially maximum UVA and the UVB light of skin damage is had strong shielding action.
Summary of the invention
The present invention is intended to propose a kind of method for preparing color cotton fiber.
According to the present invention, a kind of preparation method of color cotton fiber is proposed, comprise following step:
Enzyme process destarch step uses amylase that color cotton fiber is carried out destarch;
Silicone oil softens step, uses silicone oil to soften adopting cotton fiber;
Fine hair burn off step makes color cotton fiber pass through the fine hair of bocca with burn off color cotton fiber surface;
The mercerising step uses concentrated base to make the expanded and cell expansion in color cotton fiber molecular link space.
Wherein amylase be high temperature resistant AMS or in warm amylase.Enzyme process destarch step is carried out under 50-55 ℃ temperature, and the duration is 30-40 minute.In one embodiment, enzyme process destarch step also comprises with clear water washing and carries out processed through the color cotton fiber of enzyme process destarch and to the color cotton fiber after cleaning.
The organic group of first-selected silicone oil is a methyl.As the embodiment of replacement, the organic group of silicone oil is a kind of in ethyl, phenyl, chlorphenyl and the trifluoro propyl.
Fine hair burn off step is undertaken by gassing frame, and gassing frame has the bocca of annular.
The mercerising step comprises to color cotton fiber sprays soft water.
The preparation method of color cotton fiber of the present invention utilizes the enzyme process destarch to improve the processing speed of color cotton fiber and reduces the damage to fiber.In the follow-up processing, fiber is softened and the fine hair burn off, improve the comfort of fiber.The mercerising step can promote the appearance effect of fiber.
Description of drawings
Fig. 1 has disclosed the flow chart according to the preparation method of the color cotton fiber of one embodiment of the invention.
The specific embodiment
Fig. 1 has disclosed the flow chart according to the preparation method of the color cotton fiber of one embodiment of the invention.This method comprises following step:
S101. enzyme process destarch step uses amylase that color cotton fiber is carried out destarch.In one embodiment, amylase be high temperature resistant AMS or in warm amylase.Enzyme process destarch step is carried out under 50-55 ℃ temperature usually, and the duration is 30-40 minute.In one embodiment, in enzyme process destarch step, also comprise with clear water washing and carry out processed through the color cotton fiber of enzyme process destarch and to the color cotton fiber after cleaning.Is a necessary link in the fiber production process to the fiber starching to increase fastness.And in follow-up technology, need slurry be removed, so the step of destarch is essential, the quality of desizing directly influences the quality of fiber product, like feel, fineness, intensity etc.Adopt the starch size starching in the present most fibre technology, and the method for destarch many be main with caustic soda, sulfuric acid, hydrogen peroxide solution etc., but these chemical products not only diminish fabric, troublesome poeration, and polluting the environment.The present invention proposes to utilize enzyme preparation to carry out destarch, such as utilize AMS or in warm amylase.Under certain temperature condition, can starch slurry be become dextrin rapidly, the soluble dextrins after the liquefaction is cleaned with washing, reaches the purpose of destarch.In one embodiment of the invention, the enzyme process destarch was carried out under 50-55 ℃ temperature conditions 30-40 minute, washes afterwards removing residual slurry and enzyme, and fiber is dehydrated.
S102. the softening step of silicone oil uses silicone oil to soften adopting cotton fiber.Silicone oil can effectively increase the elasticity of fiber, makes fiber soft more.The organic group of the most frequently used silicone oil is a methyl all, is also referred to as methyl-silicone oil.Methyl-silicone oil is main selection of the present invention.Other organic groups also can be used for substituting methyl group, to improve certain performance of silicone oil.Other common group has hydrogen, ethyl, phenyl, chlorphenyl, trifluoro propyl etc.In the various embodiment of invention, also adopt a kind of organic group in ethyl, phenyl, chlorphenyl and the trifluoro propyl as silicone oil.
S103. fine hair burn off step makes color cotton fiber pass through the fine hair of bocca with burn off color cotton fiber surface.In one embodiment, fine hair burn off step is undertaken by gassing frame, and gassing frame has the bocca of annular.Color cotton fiber can be burnt the fiber surface fine hair after through the annular bocca of gassing frame.
S104. mercerising step uses concentrated base to make the expanded and cell expansion in color cotton fiber molecular link space.Mercerizing range utilizes molecular link the space expanded and cell expansion of concentrated base with color cotton fiber.In one embodiment, in the mercerising step, also spray soft water to color cotton fiber.So-called soft water is meant the water that does not contain or contain less solubility calcium, magnesium compound.In the present invention, soft water is meant that calcium salt and magnesium salts content are the water of 1.0-5.0 mg/litre.Under the effect that soft water sprays, adopt the smooth rounding of the surface change of cotton fiber, increased fiber gloss and light.
The preparation method of color cotton fiber of the present invention utilizes the enzyme process destarch to improve the processing speed of color cotton fiber and reduces the damage to fiber.In the follow-up processing, fiber is softened and the fine hair burn off, improve the comfort of fiber.The mercerising step can promote the appearance effect of fiber.
