Description
Technical field:
The present invention relates to Fabric Detection technical field, relate to a kind of method of testing for PTT fabric memory function in particular.
Background technology:
Memory face fabric, because of the performance of its uniqueness, makes it gain great popularity in textile industry.PTT memory fabric more very easily smooths with its natural fold and the soft feature such as feel, level and smooth cloth cover, shows one's talent in numerous shape memory fabric.
The memory function of PTT fabric uniqueness is more welcome in textile and garment enterprise application: for apparel modeling, can mould multiple required moulding at short notice by the simple manual mode of pinching of grabbing; To the nursing aspect of clothes, can make it to disappear by simple manual stroking taking the wrinkle that occur in process etc., make clothes recover its original formation state.The former is nursing for fabric for moulding the latter of fabric, and these two features make PTT fabric distinguish the memory face fabric with other.
Traditional memory fabric mostly is polymer memory fabric, and the memory performance of this kind fabric is the mechanical behavior relevant with factors such as glass transition temperatures, as the HEAT SETTING of chemical fiber plus material.
HEAT SETTING refers to carries out smooth process by uniform temperature and active force to chemical fiber plus material, and the planarization of the fabric after process is exactly the memory function of fabric.Therefore by the polymerization memory fabric that HEAT SETTING obtains, the heat setting temperature in arrangement process must be greater than the glass transition temperature of this polymer.But the glass transition temperature of general polymerization thing is too high or too low, be therefore difficult to the arrangement temperature controlling its HEAT SETTING.
Another part Memorability fabric, realize memory function after being arranged by some finishing agents, but finishing agent can not be combined with fiber completely, along with the increase of the use washing times of the Cumulate Sum fabric of time, this memory effect can weaken gradually and even disappears, and is therefore of short duration by the Memorability of the acquisition of this arrangement.
The memory function of PTT fabric come from PTT memorability fiber to the quick formation of mechanical deformation and extraneous effect of stress or the quick disappearance of deformation.
Great many of experiments shows, the memory performance of PTT fabric is relevant with the degree of crystallinity of ptt fiber, glass transition temperature, molecule modulus and macromolecular orientation degree etc.
Certain degree of crystallinity can make PTT fabric hand stroke just can recover shape.Compared with traditional memory fabric, the extraneous factor of the recovery reset condition of PTT fabric is power, instead of temperature, other factors such as optical, electrical.
In general, the raw material of the memory fabric of polymer has Stationary liquid and the polymer of reversible phase structure of soften-hardening, but its external condition needed for reversible phase in version determines its using value.The raw material of general memory material fabric needs certain viscosity, can the performance of anti-phase to strengthen, and ptt fiber oneself can complete memory initial state and reply the effect of initial state.
This shows, the memory function of PTT fabric is different with conventional memory fabric principle, and therefore, the evaluating method for their memory performances also should be different.
At present, the research of the domestic memory function to PTT fabric is in the starting stage, therefore not corresponding that the quality of data target to its memory function is evaluated to the memory function of PTT fabric.In order to better make PTT fabric be applied to field of textiles, must standardize to the memory performance of PTT fabric.
