Description

一种常温常压分散可染改性聚酯纤维 Normal Temperature and pressure dispersion dyeable modified polyester fibers

技术领域 FIELD

[0001] 本发明涉及一种常温常压分散可染改性聚酯纤维。 [0001] The present invention relates to a normal temperature and pressure dispersion dyeable modified polyester fibers.

背景技术 Background technique

[0002] 聚酯纤维具有物理机械性能好、弹性模量高、耐热性能好、易洗快干、抗皱性强和成本较低等优点,在合成纤维中具有广泛的应用。 [0002] Polyester fibers have good mechanical properties, high elastic modulus, good heat resistance, drying washable, wrinkle strong and low cost, etc., having a wide range of applications in the synthetic fiber.

[0003] 但是由于普通聚酯的分子链排列较紧密,导致聚酯纤维的结晶度和取向度较高、极性较小,缺乏亲水性,在聚酯纤维的曲折长链分子间没有可适当容纳染料分子的间隙,因此染料粒子不易透入纤维,其染色性差,可使用染料的种类少。 [0003] However, since the molecular chain arrangement of ordinary polyester more closely, resulting in higher crystallinity and degree of orientation of the polyester fibers, less polar, hydrophilic lacking, no twists between the long chain molecules of the polyester fiber receiving gap suitable dye molecules, dye particles thus easily penetrate into the fiber, the difference in dyeability, less dye species may be used. 这种普通聚酯纤维只能采用分散染料载体染色、高温染色或热熔染色等方法进行染色。 This conventional method can only polyester fibers disperse dye carriers, dyeing or high temperature melt staining staining. 为了改善普通聚酯纤维的染色问题,近几年国内外出现了阳离子可染的改性聚酯及由其生产的聚酯纤维或短纤,但是该改性聚酯纤维的染色条件与普通聚酯纤维的染色条件基本相同,染色温度在130°C左右,而且是在较高的压力下进行染色。 In order to improve the coloring problem of conventional polyester fibers, at home and abroad in recent years, there have been spun polyester or cationic dyeable polyester and modified produced therefrom, but the dyeing conditions of the modified polyester fiber and ordinary polyethylene ester fiber dyeing conditions substantially the same, the dyeing temperature of about 130 ° C, and dyeing is carried out at a higher pressure. 像棉、毛、麻和絹等天然纤维的染色温度较低,在高温及高压的染色处理条件下,会产生严重黄变及强度大幅下降的问题,使得聚酯纤维在与天然纤维等混纺或混用方面受到很大的限制。 Like low temperature dyeing cotton, wool, linen and silk and other natural fibers, under the dyeing conditions of high temperature and high pressure, a serious problem arises yellowing and the substantial decrease in strength, such polyester fibers with natural fibers or blends mix aspect is greatly limited.

发明内容 SUMMARY

[0004] 本发明的目的在于提供一种适合常温常压条件下染色的改性聚酯纤维,并且该纤维具有良好的耐氧化性能和抗黄变性。 [0004] The object of the present invention is to provide a modified polyester fiber suitable for dyeing under normal temperature and pressure conditions, and the fibers have good resistance to oxidation and yellowing resistance.

[0005] 本发明的技术解决方案是: [0005] The technical solution of the invention is:

[0006] 一种常温常压分散可染改性聚酯纤维,所述聚酯纤维中含有占总二元酸结构单元5〜IOmol^的带侧链且碳原子数为6以下的脂肪族二元醇结构单元,占聚酯纤维I〜5wt%的聚乙二醇结构单元,占聚酯纤维0.01〜0.50wt%的受阻酹类抗氧剂。 [0006] A temperature and pressure dispersion dyeable modified polyester fibers, the polyester fibers contained in the total structural units 5~IOmol ^ dibasic acid sidechain and 6 or less carbon atoms, an aliphatic dicarboxylic monohydric alcohol structural unit, accounting I~5wt% polyester fibers of polyethylene glycol structural units, representing a hindered polyester 0.01~0.50wt% sprinkle antioxidants.

[0007] 上述带侧链且碳原子数为6以下的脂肪族二元醇为2-甲基-1,3丙二醇、2,2-二甲基-1,3丙二醇、2-甲基-1,4-丁二醇、2,3-二甲基-1,4-丁二醇、2-甲基_1,5-戊二醇、1,2_丙二醇,优选2-甲基_1,3丙二醇。 [0007] The sidechain and 6 or less carbon atoms, an aliphatic diol is 2-methyl-1,3-propanediol, 2,2-dimethyl-1,3-propanediol, 2-methyl-1 1,4-butanediol, 2,3-dimethyl-1,4-butanediol, 2-methyl pentanediol _1,5-, 1,2_-propanediol, 2-methyl _1 preferably, 3-propanediol. 带侧链且碳原子数为6以下的脂肪族二元醇可以增加高分子链段之间的空隙,使得染料能够更容易的渗透入纤维中,实现常温常压可染的性能,同时纤维具有较高的机械特性。 Sidechain and a carbon number of 6 or less aliphatic diol may increase the gap between the polymer chain segments, so that the dye can more easily penetrate into the fiber, temperature and pressure to achieve dyeability properties, while fibers having high mechanical properties. 该带侧链且碳原子数为6以下的脂肪族二元醇的含量占纤维中总二元酸结构单元的5〜IOmol %,如果其含量超过IOmol %的话,纤维的机械特性会有所下降,同时纤维的收缩特性回变大,由该纤维所制成的织物的尺寸稳定性会变差。 The content of the side chain and with 6 or less carbon atoms, an aliphatic diol accounts fibers 5~IOmol% total dibasic acid structural unit, if the content thereof exceeds IOmol%, then the mechanical properties of the fiber will decrease , while the shrinkage characteristics of the fiber back becomes large, the fabric made from the fibers of the dimensional stability is deteriorated.

[0008] 为了近一步提高染色性能,本发明聚酯纤维中还含有I〜5wt%的聚乙二醇结构单元。 [0008] In order to improve the dyeing performance closer, the polyester fiber of the present invention further contains I~5wt% polyethylene glycol structural units. 聚乙二醇结构单元的存在可以进一步增加分子链之间的空隙使得染料更容易分散进去,同时还降低了聚酯纤维结构的紧密度从而使染色温度降低。 The presence of the polyethylene glycol structural units may be further increased so that the gap between molecular chains of the dye more easily dispersed in, while reducing the tightness of the polyester fiber structure so that the dyeing temperature. 但是过量的聚乙二醇结构单元会导致纤维的耐热性下降,且影响纺丝性能,容易出现断丝或者飘丝现象。 However, an excess of polyethylene glycol structural units may decrease the heat resistance of fibers, and the spinning performance impact prone to broken wires or filaments floating phenomenon.
