Description
Technical field
The invention belongs to looped fabric staining technique field, a kind of chemical fibre knitting is specifically related to without preshrunk dyeing.
Background technique
Science fabric is the novel dress material that RECENT DEVELOPMENTS is got up, and type is more.Here it is primarily referred to as by chemical fibre
The pure spinning be processed into, blended or intertexture, that is to say, that the fabric being made by pure chemical fiber does not include mixed between natural fiber
It spins, intertexture, the characteristic of chemical & blended fabric determines that use is natural or synthetic by the characteristic for the chemical fibre for being made into it itself
Polymer substance is fiber made of raw material.Common textile, as adhesive fabric, dacron khaki, polyamide fibre socks, acrylic fibers knitting wool with
And pp carpet etc., it is all made of chemical fibre.According to the difference of raw material sources, chemical fibre can be divided into: 1. artificial
Fiber has viscose rayon etc. with natural high molecular substance (such as cellulose) for raw material；2. synthetic fibers, to synthesize macromolecule
Object is raw material, there is terylene etc.；3. inorfil has glass fibre etc. using inorganic matter as raw material.First is extracted out since 18th century
Since artificial silk, chemical fibre kind, fiber-forming processes and spinning technique technology have very big progress, the system of chemical fibre
It is standby, spinning melt or solution first usually is made in natural or synthesis polymer or inorganic matter, then by filtering, meter
Amount, is extruded as liquid thread by spinning head (plate), and then solidification forms fiber.Fiber at this time is known as as-spun fibre.It
Mechanical property is very poor, cannot directly apply, it is necessary to can just meet textile process by a series of post-processing procedures and what is used want
It asks.Post-processing mainly carries out stretching and heat setting to fiber, to improve the mechanical property and dimensional stability of fiber.Stretching is
It is orientated macromolecular or structural unit in as-spun fibre along fiber axis；Heat setting mainly makes internal stress relaxation in fiber.It is wet
The post-processing for spinning fiber further includes the processes such as washing, oiling, drying.When spinning filament yarn, cylinder can be wound by above-mentioned operation；
Curling, cutting and packing process must also be increased when spinning staple fiber, it is all to dye that the dyeing of looped fabric is most of at present
It is preceding that preshrunk is carried out to cloth, but there have some looped fabrics to will lead to fiber fastness after preshrunk to be poor.
Summary of the invention
The present invention mainly solves technical problem present in the above-mentioned prior art, provides a kind of knitting of chemical fibre and contaminates without preshrunk
Color technique.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: a kind of chemical fibre knitting nothing is pre-
Chemical fibre looped fabric is first put into slurry pool and carries out desizing by contracting dyeing, and slurries use native starch slurries, in native starch
The amylase of the NaOH and 1-6g/L of 5-8g/L is added in slurries by quality；The chemical fibre looped fabric of desizing is refined again,
It is bleached being put into Bellmer by the chemical fibre looped fabric refined, sodium hypochlorite bleaching agent, bleaching is used in Bellmer
The pH value of agent solution is 5-11, and the chemical fibre looped fabric by bleaching is sent into chain mercerizer and carries out mercerising, chemical fibre looped fabric
The slot that dips for first passing through chain mercerizer is dipped, then carries out tentering by the taut cloth roller of chain mercerizer, then pass through cloth
The cloth gripper expanding chain of pincers mercerizing machine will be put into high temperature and denseer burning by the chemical fibre looped fabric of mercerising finally by alkali steam box
Alkali decrement treatment is carried out in lye, the polyester fiber in chemical fibre looped fabric is in sodium hydrate aqueous solution, fiber surface polyester point
The ester linkage hydrolyzing of subchain is broken, and constantly forms the hydrolysate of different polymerization degree, ultimately forms water-soluble terephthalic acid (TPA)
Sodium and ethylene glycol will carry out high-temperature pressure dyeing, the chemical fibre needle that will finally dye by the chemical fibre looped fabric of alkali decrement treatment
Woven fabric carries out thermoforming.
Preferably, NaOH solution is added in described dip in slot, the concentration of NaOH is 200-280g/L, NaOH on the cloth cylinder that stretches tight
30-40Sec is reacted with chemical fibre looped fabric, chemical fibre knitted fabric tentering 10-20Sec is being inhaled and gone with sweeping away by cloth gripper expanding chain
Alkali steam box removes the alkali on chemical fibre looped fabric.
Preferably, the medicament of the refining uses the medicament based on sodium hydroxide, supplemented by surfactant.
Preferably, the process sequence of the thermal finalization is divided into three processes, first chemical fibre knitted fabric is determined
Type, then the semi-finished product of chemical fibre looped fabric are carried out shaping, finally to the chemical fibre knitting finished fabric sizing after dyeing.
The invention has the benefit that chemical fibre looped fabric carries out chemical fibre looped fabric by the amylase in farinaceous size
Desizing, desizing is high-efficient and does not damage fiber, and by the way that sodium hydroxide solution is added in farinaceous size, farinaceous size is in alkali
Effect is lower to occur swelling (or extruding) phenomenon, does not chemically react, and makes slurries from gelatinous transformation sol form, reduces fine
Binding force between dimension and slurries, thus convenient for cleaning.Chemical fibre looped fabric passes through based on sodium hydroxide, supplemented by surfactant
Refinery systems in refined, fiber impurity can be removed, improve the processing performance and wettability of fabric.Chemical fibre looped fabric
After carrying out mercerization finish by chain mercerizer, the dimensional stability of chemical fibre looped fabric is improved, washing shrinkage reduces, breaking strength
Reduce and appearance has silky gloss.Chemical fibre looped fabric is handled by thermal finalization, can eliminate answering for the interior accumulation of chemical fibre looped fabric
Stress-strain makes fiber fastness height, the surfacing corrugationless of chemical fibre knitted fabric, and thermal stability is good, improves chemical fibre knitted fabric
Wash and wear.
