(mensuration of melting mass flowrate (MFR))
The mensuration of melting mass flowrate is carried out according to JIS K7210.Herein, MI measures according to the condition D (test temperature be 190 DEG C, loading be 2.16kg) of attached book A table 1, and MFR measures according to condition M (test temperature be 230 DEG C, loading be 2.16kg).
(manufacture of fiber)
Use and form the spinning mouth of concentric sheath core pattern section, carry out melt spinning with the thermoplastic resin shown in predetermined extrusion temperature his-and-hers watches 1 ~ table 2, obtain fibre profile with volume basis be the concentric sheath core pattern of 50/50 do not extend fiber.Now, utilize oiling roller, the fibre finish shown in table 1 ~ table 2 is attached to and does not extend fiber.Utilize the hot-rolling of 90 DEG C to be extended by the fiber that do not extend of gained, utilize crimper (crimper) to give and crispatura, make extension fiber by this.Thereafter, utilize hot air circulating dryer to extend fiber drying, utilize cutting machine to make the staple fibre of 2.2dtex with 51mm cutting, used as sample fiber.
(composition of fibre finish)
The composition of the fibre finish used in each example is shown in table 1 ~ table 2.The unit of this composition is quality %, and the total amount of the active ingredient in fibre finish is set as 100 quality %.
(adhesion amount of fibre finish measures)
Utilize roller card testing machine (large and machine work (having) manufactures) that sample fiber is made fiber web, take out 2g from fiber web and use rapid residual fat extraction equipment (East Sea gauge (stock) manufactures, " R-II type ") to measure.Use methyl alcohol 25ml as extractant.
Following formula is utilized to calculate adhesion amount.
Adhesion amount (quality %)=extraction quantity (g) ÷ 2 × 100 of finishing agent
(resistance to discoloration test)
Utilize roller card testing machine (large and machine work (having) manufactures) that the sample fiber of gained in above-mentioned steps is made carded web, utilizing acupuncture press (needle punch press machine) that this net is made basic weight is about 200g/m
2+ 20g/m
2nonwovens.This sample is cut into vertical 8cm × horizontal 8cm, be arranged at the top 80cm (environment temperature is 100 DEG C ± 5 DEG C) of petroleum furnace burning things which may cause a fire disaster.Expose 3 hours in burning gases after, take out sample.Utilize colour difference meter (Suga Test Instruments Co., Ltd. manufacture, " model SM-4 ") numerical value of the yellowness index (Yellow Index, YI) on the surface of test specimen before and after determination test, calculate its difference Δ YI, evaluate with following 3 grades.
Good A > B > C is poor
If Δ YI is less than 6, be then considered as discoloration-resistant excellent, be evaluated as ' A '.
If Δ YI is more than 6 and is less than 8, be then evaluated as ' B '.
If Δ YI is more than 8, is then that discolouration is high, therefore is evaluated as ' C '.
(Nonwovens)
Utilize roller card testing machine (large and machine work (having) manufactures) that the sample fiber of gained in above-mentioned steps is made carded web, utilize suction drier (suction dryer) to process (abbreviation TA) by the ventilation of the temperature described in table 1 ~ table 2 and make this net heat then, obtaining basic weight is about 23g/m
2+ 2g/m
2nonwovens.
(absorb and evaluate)
The Nonwovens of gained in above-mentioned steps is cut with vertical 10cm × horizontal 10cm, be arranged on the absorber that encased by paper handkerchief (tissue), 2ml suction pipe is utilized respectively to drip 1 artificial urine in 10 places, according to from Nonwovens absorbed number and calculate absorptivity by following formula on the surface.
Absorptivity (%)=(absorbed number (individual)/10) × 100
Thereafter, utilize the artificial urine of 50ml to rinse Nonwovens, after abundant drying, carry out dropping in the position dripped in the past and again measure absorptivity.Repeating to implement aforesaid operations reaches till 0% until absorptivity, judges, evaluate durable hydrophilic with following 3 grades.
Good A > B > C is poor
When the absorptivity of the 3rd time is more than 0%, be considered as absorbability excellent, be evaluated as ' A '.
The absorptivity of the 2nd time more than 0% and the absorptivity of the 3rd time is 0% time, be evaluated as ' B '.
When the absorptivity of the 2nd time is 0%, be considered as absorbability difference, be evaluated as ' C '.
Moreover the artificial urine used in this evaluation uses by following compositions than preparation person.
Urea 2.00 quality %
Sodium chloride 0.80 quality %
Magnesium sulfate 0.08 quality %
Calcium chloride 0.03 quality %
Ion exchange water 97.09 quality %
In following table 1 and table 2, by the formation of fiber, processing conditions and illustrate in the lump according to the result that above-mentioned test and assay method are carried out testing, measuring.
