用于纺丝的挤出PBT材料
PBT纺丝等级
1。PBT纤维的强度为30.91～35.32cN/tex，伸长率为30%～60%，熔点为223℃，结晶速度比聚对苯二甲酸乙二醇酯快10倍，具有优异的伸长率。弹性回复率长，柔软易染
2。PBT纤维具有聚酯纤维所共有的一些性能，但由于PBT大分子基本链节上较长的柔性部分，PBT纤维的熔点和玻璃化转变温度低于普通聚酯纤维，增加了纤维大分子链的柔韧性和弹性
3。PBT纤维具有良好的耐久性、尺寸稳定性和良好的弹性，弹性不受湿度的影响
4。PBT纤维及其制品手感柔软，吸湿性好，耐磨性好，纤维卷曲性好，拉伸弹性和压缩弹性好，弹性回复率优于聚酯。PBT纤维在干湿条件下都具有特殊的拉伸性能，其弹性不受环境温度变化的影响
5。它具有良好的染色性能，普通分散染料可用于无载体常压沸腾染色。染色后的纤维色泽鲜艳，具有优良的色牢度和耐氯性
6。它具有优异的耐化学性、耐光性和耐热性

Extrusion PBT Material for Spinning
PBT Spinning Grade
1. The strength of PBT fiber is 30.91～35.32cN/tex, the elongation is 30%～60%, the melting point is 223℃, its crystallization speed is 10 times faster than polyethylene terephthalate, and it has excellent elongation. Long elastic recovery rate and soft and easy to dye characteristics.
2. The fiber made of PBT has some properties shared by polyester fiber, but due to the longer flexible part on the basic chain link of PBT macromolecule, the melting point and glass transition temperature of PBT fiber are lower than that of ordinary polyester fiber. , Resulting in increased flexibility and elasticity of the fiber macromolecular chain.
3. PBT fiber has good durability, dimensional stability and good elasticity, and the elasticity is not affected by humidity.
4. PBT fiber and its products have soft hand feeling, good moisture absorption, abrasion resistance and fiber crimp, excellent tensile elasticity and compression elasticity, and its elastic recovery rate is better than that of polyester. PBT fiber has special stretchability under both dry and wet conditions, and its elasticity is not affected by changes in ambient temperature.
5. It has good dyeing performance, and ordinary disperse dyes can be used for atmospheric boiling dyeing without carrier. The dyed fiber has bright color, excellent color fastness and chlorine resistance.
6. It has excellent chemical resistance, light resistance and heat resistance.
is one of the professional extrusion pbt material for spinning manufacturers, you can order high quality extrusion pbt material for spinning at good price from our factory.
