Milling formulations detection fulling agent component tests
Fulling agent formulation components is composed mainly by the
surface active agents, softeners, antifoaming agents and other
chemical reagents.Micro-spectrum technology based on the analysis of the test course
mastery milling agent for textile dyeing process, specialized
milling formulations detection fulling agent component tests.
, Shrink it agent Overview
Fulling agent formulated products are mainly used in woolen fabric.Wool fulling (including senior animal fibers) mainly by the
directional friction effect, the injury is a condensing process in
the improper actions of friction, thus reducing friction
coefficient of static friction is essential, according to the
traditional sequence, the various types of surface-activeinitially to a conventional condensing agent reduces the order of
the coefficient of static friction properties, it aids given bits.Fulling agents, temperature, and pressure, give full play to the
wool fulling performance, so that the fabric is tightly, feel rich
soft fluff process table.
Second, fulling the purpose and the basic principle
(1) close texture, increased thickness and strength improve,
flexible, warm and enhancements;
(2) exposed on the surface covered by the layer of fluff to the
tissue and improving the appearance of fabric;
(3) up to the required length, width and unit area weight;
(4) conceal it match some weaving defect, and not clearly exposed
in the face it.
2, fulling principle
Full use of the fulling of the wool, and to achieve the fulling the
purpose.Wool felting performance in the following three aspects:
Directional friction effect that (1) wool fiber cuticle layer the
DFE (Directional Frictional Effect);, and the DFE = (u2-u1) / (u2 +
Where: u1-from the hair root to the the Tippy direction running
u2-from Tippy run coefficient of friction direction of the hair
roots; wool directional friction effect and the greater the
stronger the fulling of the wool fibers.
(2) wool fibers excellent elasticity
Acute elastic recovery of the wool of the wool fibers to produce a
certain degree of retraction, between the wool fibers relative
motion occurs many times, and will procure wool interleaving and
tangles favor fulling.
(3) natural crimp properties of wool fibers
The wool straight becomes curly process, the inevitable with
similar hair entwined, At the same time the the wool sport is an
irregular peristalsis.Wool curled more and more fulling.
To sum up, shrink it, you can choose a suitable condensing it
formulated products, wetting the wool fibers, expansion, the scales
tip Zhang farther apart.At this time, by the fulling machine applied external force,
forcing the the wool fibers mobile, interspersed with each other to
form a mesh, the free state and the tip was covered on the surface
of the fabric so that the surface to produce fluff, to achieve
condensing it's purpose.
Third, the condensing agent formulation main component selection
By surfactant and the level of development, is not a single
component additives can be enriched in all the features required of
the condensing agent and therefore must engage aid compounded.Typically, fulling order of the reduced static friction coefficient
of the various types of surface active agents in the formulations
are as follows: cationic> polyol ester type non-ionic>
anionic> polyethylene glycol type non-ionic mineral oil (from
left to right the ability to reduce the static friction is reduced).
Conventional condensing agent LS 209, the anion of the sodium
alkylbenzene sulfonate (ABS), Lamepon (alkaline state) are; R5, 824
benzene is a polyethylene glycol type non-ionic, order row Next, so its shrink resistance merely low-grade level, switch cationic
or polyol quinoid nonionic shrink effect will be greatly improved.With the industrial development of the surfactant, various
additives can elect a certain kind, and it reduced static friction
capacity far stronger than listed.The alkaline earth metal fatty acid soaps, polyethers and poly
(ethylene oxide), mixed non-ionic, no less than the cations and
polyol ester type differential, and this is also the importance of
the system condensing it formulations.
