Although shown that P (3HB-co-4HB) product is prone to biodegradation in soil, mud and sea water, but because of in water
Lack microorganism and make the biodegradation rate in water very slow (Saito, Yuji, Shigeo Nakamura, Masaya
Hiramitsu and Yoshiharu Doi, " Microbial Synthesis and Properties of Poly (3-
Hydroxybutyrate-co-4-hydroxybutyrate), " Polymer International 39 (1996), 169-
174).Therefore the pot-life of P (3HB-co-4HB) product is in the cleaning of the most seal-packed dry-storage, clean solution etc.
Environment should be the most excellent.But, when being placed in such as soil, river, river silt, sea water and the fertilizer comprising microorganism
With time in the dirty environment of the compost of sand, mud and sea water, P (3HB-co-4HB) fabric, thin film and the encapsulating material abandoned should
When being prone to degraded.It should be noted that, polylactic acid (PLA) is not easy to biological fall in above dirty environment and under ambient temperature
Solve, but compost must be carried out.First, PLA polymer must be resolved into less polymerization by the temperature in compost heap and humidity
Thing chain, finally resolves into lactic acid.Less polymer segments and lactic acid are disappeared by the microorganism in compost and soil as nutrient
Them are consumed.Therefore, PHA (PHA) mixture of P (3HB-co-4HB) product such as with PLA should strengthen
The degraded of the product being made up of the blend of PHAs-PLA.It addition, the product being made up of the blend of PHA and PLA should be
Enhanced in cleaning ambient the pot-life.But, at 10 years of the past, the price of PLA was only greatly reduced
More little higher than the synthetic polymer of such as polypropylene and PET polyester；Meanwhile, the price of PHAs continues to keep than PLA's
High 2 to 3 times, this PLA can be synthesized by lactic acid on a large scale.PHAs has the antibacterial with specific carbon source to make, and must use molten
Agent is extracted from antibacterial.Therefore, commercially cannot realize mixing PHA with PLA more than 25%, be formed with melt extruded and produce
Product, such as textile fabric, knitting and adhesive-bonded fabric, thin film, food container etc..
Table 1 shows the layer of biodegradation adhesive-bonded fabric, Biodegradable film and adhesive-bonded fabric and Biodegradable film

Laminar structure is bonded together.
The intensity of table 1 polymer and obstruct attribute
* DSN: represent due to high resiliency not by bursting
As shown in table 1, pure (100%) PBAT thin film (sample 1) of 9 μm has good percentage elongation and at CD in MD direction
Elongation at break on direction is up to more than 300%.Sample 1 to 5 can not be performed bursting strength test, because all these
Thin film and laminar structure elastic the best, will not rupture in test process and the most also will not show deformation.
The moisture vapor speed of sample 1 was fairly good, for every 24 hours 3380g/m2, hydrostatic head is 549mm simultaneously.There is 20% carbonic acid
Calcium (CaCO3) PBAT thin film (sample 2) there are the data similar with sample 1, wherein WVTR is the most relative with head lower.Anticipated
Similar with sample 1 and 2 and there is the PBAT thin film of 6 μm or following less thickness also there is good percentage elongation and higher
WVTR, although head may be lower.Melt-blown sample 3 comprises 80%(polyolefinic poly-based on Vistamaxx
Compound is had high resiliency and is made by ExxonMobil) and the PP of 20%, because this fabric is appropriate openning, therefore have
MD and the CD percentage elongation of about 300% and every 24 hours 8816g/m2High WVTR.Although MB Vistamaxx fabric is not raw
Thing degraded, but it is possible to the example of a kind of elastic non-woven material made from biological degradation polyalcohol, described biology
Degradation polymer such as has PBAT and other biological degradation polyalcohol of very high elongation rate and deformation recovery capability.Sample 3
Head at a relatively high, for 1043mm, show that it has good barrier property.It should be noted that, the PP of 20% is added to
Vistamaxx polymer beads, and carried out physical mixed before blend feeding MB extruder, and carry out melted so that
Vistamaxx MB fabric will not be the most glutinous.If the Vistamaxx of melt-blown 100%, then will be the most glutinous, thereby increases and it is possible to tie in rolling
Block, and be difficult to launch (un-wind) in follow-up lamination or use.
Compared with only Vistamaxx, use hot-melt adhesive and there is the pure PBAT of Vistamaxx and comprise 20%
CaCO3The laminar structure of PBAT significantly increase MD and CD toughness.This sample also has the highest MD percentage elongation and especially
High CD percentage elongation (sample 4 is 390%, and sample 5 is 542%).Sample 4 and sample 5 also have significantly high MVTR value, respectively
For every 24 hours 1671 and 1189g/m2, and there is high water head, respectively 339 and 926mm water.Again it should be noted that
PBAT thin film can directly extrusion coating on MB 100%Vistamaxx or have on the MBVistamaxx of some PP and
Use or do not use hot-melt adhesive, and extrusion coating has allowed for using the PBAT thin film of more Thin Specs, as little as 4 or 5 μ
M, thus has higher MVTR, but is likely to be of lower head.
The target weight of black SB PLA is 80g/m2, MD toughness be 104N and CD toughness be 31N, but have lower
MD elongation at break, is 3.6%, and has high CD elongation, be 30.7%.Bursting strength is 177KN/m2And WVTR is suitable
Height, for every 24 hours 8322g/m2, and head is quite obvious, for 109mm.Molten hot glue is used to be laminated on pure PBAT
MD and the CD toughness of the black SB PLA of 80gsm is higher than simple SB PLA respectively, and it is respectively 107 and 39N, but CD extends
Rate is only 9.8%.But the PBAT being laminated SB PLA has higher bursting strength, for 220KN/m2.But breathability is still
So keeping excellent, WVTR is every 24 hours 2459g/m2, and there is the highest head, for 3115mm water.It is laminated and has comprised
20%CaCO3The SB PLA of PBAT there is the attribute similar with sample 8, except head ratio is relatively low, although being still up to 2600mm
Water.There is thinner PBAT thin film and there is the SBPLA lamination of thinner PBAT thin film by extrusion coating formation of deposits especially
Structure, can produce the protective garment for having the medical science of high MVTR, industry or sports applications, because its energy is comfortable and easy to wear and has height
Net water head is for barrier-protection.Can be by before or after the lamination of thin film, in PBAT film side or arbitrary
Apply finishing agent (fluorine silicon or other type of finishing agent) on SB PLA on side, further enhance barrier-protection.Also can lead to
Cross, before or after the lamination of thin film, MB PLA and SB PLA is laminated combination to strengthen barrier-protection.It is also possible to finishing agent
Add in the polymer melt for preparing such as PBAT thin film, SB or MB PLA.
When two-layer SB fusible the combining of PLA is formed sample 9, MD and CD toughness and bursting strength essence
On be the twice of sample 6 of a Rotating fields.Corresponding from 110g/m2Elongation at break (the % of patient's raising sling that SB PP produces
Percentage elongation) target MD and the most every 5cm of CD toughness is 200 and elongation values in 140N, MD and CD is the most all
40%.As shown in table 1, the MD toughness of the SB PLA layer of two adhesive bond is 215N, but CD toughness is only required rank
50%.And required minima that the elongation at break of MD and CD is than 40% is much lower.Can be by before SB fabric presses
The PBAT of PLA and 5 to the 60% or PBAT of preferably 20 to 50% is blended, to strengthen MD and the CD percentage elongation of SB PLA.Separately
Outward, can have required MD and CD toughness and elongation values and beat exposure rear stability by blended for PBAT and PBS and PLA to obtain
Fabric.It addition, can be by the technique long silk screen of bonding SB of non-thermal calendering, to obtain bigger multi-direction intensity and percentage elongation
To comprise Hydroentangled formula and acupuncture type.110g/m can be generated2More heavy weight acupuncture SB PLA without by two or
Multiple SB PLA fabric laminated or adhesive bond together with obtain needed for intensity and elongation values.
Also show the hoist cable being made up of the fabric of the biodegradable/compost of such as PLA, from raw material stage to factory
Polymer is formed, and the greenhouse gas emission being produced such as carbon dioxide is much lower.Such as, produce in PLA polymer, every thousand
Gram polymer produces the carbon dioxide of 1.3 kilograms, accordingly, produce every kilogram of PP by produce 1.9 kilograms carbon dioxide and
Produce every kilogram of PET and will produce the carbon dioxide of 3.4 kilograms.And from feed stage to the production of polymer factory, PLA makes
By less non-rechargeable energy, producing in Ingeo board PLA, per kilogram polymer uses the non-rechargeable energy of 42 megajoules,
During PP by comparison produces, per kilogram polymer uses the non-rechargeable energy of 77 megajoules, and during PET produces, per kilogram gathers
Compound uses non-rechargeable energy (" the The Ingeo of 87 megajoulesTMJourney, Nature Works LLC Brochure
