Interpretation
The structure of the imitative dimity of multiple turn terylene
The structured testing of the imitative dimity of multiple turn terylene the results are shown in Table 2
Can find out that from table 2 No. 3 yarn adhesion segment length is the longest, No. 1, No. 2 and No. 6 are also bigger, No. 4 CATION yarn adhesion segment length minimums, and non-adhesion section number is maximum, and No. 1 the non-adhesion section of yarn number is minimum.
Multiple turn terylene is imitated dimity mechanical property
The imitative dimity Mechanics Performance Testing of multiple turn terylene the results are shown in Table 3, from table 3, can see, No. 4 CATION yarn breakage intensity is the poorest, other yarn breakage strength ratios are more approaching, this is because No. 4 cationic-dyeable terylene are by adopting the ionic copolymerization monomer, the ion seat is imported in the polyester construction, these ionic compounds are in the initial segment importing polymer of polymerization, the ionic copolymerization monomer that is used for the polyester sex change, in the polymer chain molecule, there is this comonomer, the structure that can make copolyester fiber is than conventional polyester fibre compact and organize pine, and the intensity of CATION yarn is reduced.
The yarn regain
Yarn regain test result is seen Fig. 2, and as can be seen from Figure 2, the regain of No. 3 yarns is minimum, secondly is No. 6 yarns, No. 4 yarn regain maximums.This is that yarn adhesion segment length is big more because the adhesion length of No. 3 yarns is the longest, and fiber surface area is little, and the yarn regain is little.No. 4 yarn regain maximums, this is because of the cationic-dyeable terylene, its structure is than conventional polyester fibre compact and organize pine, and the regain of CATION yarn is increased.Yarn adhesion segment length is more little in addition, and fluffy section of yarn is many more, makes with air contacting surface is long-pending to increase, and the moisture of fiber surface absorption is increased, thereby its regain is improved.
The yarn elastic recovery
Yarn elastic recovery test result sees Table 4, can find out from table 4, and secondly the elastic recovery rate maximum of No. 4 yarns is No. 5 yarns, the elastic recovery rate minimum of No. 3 yarns.This is that non-adhesion segment length is the longest because the non-adhesion section number of No. 4 CATION yarns is maximum, and its elastic recovery is best.The elastic recovery rate minimum of No. 3 yarns, be because yarn adhesion segment length is the longest, elastic recovery rate size and the bulking intensity size of yarn, the adhesion segment length of yarn of yarn have certain contact, the bulking intensity of yarn is low more, the adhesion segment length is big more, the adhesion percentage is high more, and its elastic recovery rate is just low more.
The key property of fabric
Fabric key property experimental result sees Table 5, by finding out in the table, No. 3 and No. 6 fabric ultimate strengths are big, mainly be because No. 3 and No. 6 yarns are thicker, No. 1 fabric ultimate strength is big, be that heater temperature is brought up in the softening point certain limit because No. 1 fabric yarn adhesion length is bigger, the strand molecular structure rearranges, the degree of orientation increases, and makes powerful increasing.No. 4 fabric strength minimums, percentage elongation is higher, this be because No. 4 for the CATION yarn, the structure of polyester fiber is less more dense and organize pine than conventional polyester fiber, and the intensity of CATION yarn is reduced, elongation increases, and it can also be seen that from table the broadwise ultimate strength is less than the warp-wise ultimate strength, this be because through close greater than filling density, the stressed yarn radical of warp-wise is many, so the warp-wise ultimate strength is bigger than broadwise ultimate strength.The imitative dimity of multiple turn terylene has powerful preferably and extension at break characteristic.No. 7 natural flax fibre has demonstrated ultimate strength preferably, but elongation at break is far smaller than the imitative dimity fabric of multiple turn terylene.
The hard and soft property of fabric is meant the bending rigidity and the pliability of fabric.From table, can find out in the imitative dimity fabric of multiple turn terylene No. 3 and No. 6 fabric bending lengths bigger, feel is the hardest, this is bigger because of their fiber numbers, and the adhesion total length is higher.No. 4 and No. 5 fabrics are the most soft, and this is because No. 4 and No. 5 yarn adhesion length are smaller.Fiber is under identical thickness situation, and the filament radical is many, and is soft more.No. 2 yarn adhesion length is longer, but because filament is thin, can improves its feel and make it more soft.From table, can obviously find out the bending length maximum of No. 7 natural linens, illustrate that the pliability of the imitative dimity of multiple turn terylene is better than natural linen.
Also can find out the bigger than natural linen through the anxious elastic angle of broadwise of multiple turn dacron from table, multiple turn dacron is better in the rapidly rebound of the utmost point in the short time.Because the imitative dimity of multiple turn terylene is to be made by the higher polyster fibre of initial modulus, multiple turn dacron has better crease recovery than natural linen.
ABRASION RESISTANCE is the characteristic that fabric has opposing wearing and tearing, and No. 3 and No. 6 fabric abrasion resistance are good, and this is the longest because of the adhesion length of No. 3 and No. 6 yarns, and adhesion length is long, and fiber surface area is little, and suffered friction is just little, so ABRASION RESISTANCE is good.No. 2 fabric abrasion resistance can be poor, and this is because fiber number is thinner, easily rubs, and ABRASION RESISTANCE is poor.No. 4 is cationic fabric, and the CATION yarn strength is lower, and is not wear-resisting.The ABRASION RESISTANCE of the imitative dimity fabric of multiple turn terylene is better than natural linen.
Experimental data by present embodiment can know that the imitative dimity of the multiple turn terylene of present embodiment production has following characteristics:
(1) the imitative dimity of multiple turn terylene has powerful preferably and extension at break characteristic.Its elongation at break is far longer than natural hemp fabric.
(2) the imitative dimity fabric of multiple turn terylene has better flexibility, crease recovery and ABRASION RESISTANCE than natural linen.
(3) adhesion segment length size and number and filament thickness are the principal elements that influences yarn and fabric property.
