Description

一种用于羊毛物理细化的化学定型剂
(一） 技术领域 本发明涉及一种化学处理剂， 特别是涉及一种用于羊毛物理细化的化学定 型剂。
(二） 背景技术
羊毛物理细化产品是近年来国际对羊毛进行改性处理形成新型细化纤维取 得的重大成果。 此技术是将天然羊毛在一定的助剂、 温度、 湿度、 及拉伸应力 的共同作用下， 实现机械拉伸， 使其纤维变长变细， 从而获得细化的并兼有丝 般光泽绒般手感的超细羊毛制品。 此纤维的问世， 顺应了当今世界上毛纺面料 轻薄化、 高档化、 生态、 环保、 舒适的理念。 羊毛主要成分为角质， 羊毛角质是由多种 α—氨基酸縮合而成的链状大分 子， 分子间形成大量的盐式键， 胱氨酸键和氢键， 使角质大分子具有网状结构。 羊毛蛋白分子链中通常情况下以 α螺旋链状态存在， 呈螺旋状卷曲， 当毛纤维 受到特定条件处理时， 分子形状可以由卷曲的 α型转变成伸长的 3型结构， 这 种空间构象的转变能力使羊毛纤维具备了拉伸的前提条件。 鉴于羊毛的特殊的 变形能力， 可通过拉伸的方法， 将羊毛纤维分子结构中的 α型结构转变为 P型 结构， 并将羊毛纤维较长久地保持在伸长后的状态。 为了实现并保持纤维构型 的转变， 必须设法拆开大分子链之间联系的横向键， 充分降低拉伸应力， 使拉 伸和细化得以实现。 研究表明： 将纤维束浸入合适的化学助剂， 使其充分的润 湿、 膨化， 并拆散其内部的各种盐式键、 氢键及二硫键， 在适宜的温度、 湿度 条件下， 对加捻或无捻纤维施加 τ "定的机械力进行拉伸， 再通过热及化学定型 使其伸长后的形态保持稳定即可达到羊毛物理细化之要求。
1 确认本 (三） 发明内容
本发明基于上述目的， 提 了一种用于羊毛 理细化的化学定型剂。
本发明的技术方案是这样实现的。
本发明的羊毛物理细化化学定型剂将被拆散的大分子链之间联系的横向键 再通过连接剂、 稳定剂和树脂整理剂的合理组合配方连接起来， 使其细化后的 形态永久地保持下来， 并能够满足羊毛纤维后步染整加工之要求， 使其细化后 纤维的沸水回縮达到普通羊毛的沸水回縮率指标要求。 其主要作用机理是通过 化学氧化和交联作用达到理想要求。
本方案的羊毛物理细化化学定型剂， 由连接剂、 稳定剂、 树脂整理剂和水 组成， 其重量百分含量分别是： 连接剂 0. 1%〜5%， 稳定剂 0. 5%〜5%， 树脂整理 剂 0. 5%〜： L0%， 其余为水。
所述的连接剂是过氧化氢、 高锰酸盐、 过硫酸盐的一种， 所述的盐是它们 的钾、 钠、 胺盐。
所述的稳定剂是醋酸与氢氧化钠的组合、 柠檬酸、 磷酸的一种。
所述的树脂整理剂为丙烯酸酯类、 改性有机硅树脂类整理剂的一种。
具有润化作用的有机硅主要 ¾"硅油乳液和羟基硅油乳液， 在它的主体分子 结构中导入氨基、 羟基、 环氧基、 聚醚基等就形成了改性有机硅， 导入氨基就 称作氨基改性有机硅氧烷。
本发明的有益之处在于： 该化学定型剂能够使细化后的羊毛纤维在新的位 置上重新建立稳固的大分子网状结合， 从而有效地控制物理细化羊毛纤维的沸 水回缩率， 满足后步染整加工要求。 有效地解决了国内国外现有的羊毛物理细 化产品存在的共性问题——羊毛细化后沸水回缩率高， 造成产品在加工及服用 过程中稳定性差的缺陷， 满足羊毛纤维高支化、 功能化、 羊毛制品轻薄化的市 场需求。
(四） 具体实施方式
下面结合实施例对本发明作进一步说明。
实施例 1 :
取过氧化氢 1. 5ml， 加入一定量的水混合成 100ml， 制成处理液 A。
取 Polymer G (丙烯酸脂类整理剂） 5g 、 醋酸 3. 8ml、 氢氧化钠 2g， 加入 一定量的水混合制成 100ml处理液 B。
把物理细化羊毛浸入处理液 A中定型， 温度 30°C， 时间 5分钟； 然后再浸 入处理液 B中， 温度 35°C， 时间 8分钟。 取出后水洗， 烘干。 将定型处理后的 羊毛放入 100°C的沸水中处理 30分钟， 取出后测试处理后纤维长度缩短值与处 理前纤维的长度之比为沸水回缩率， 本实施例定型后羊毛纤维的沸水回缩率为 1. 9%。
实施例 2: '
取高锰酸钾 0. 5ml， 加入一定量的水混合成 100ml， 制成处理液 A。

按照实施例 1方法进行处理,处理后纤维测试沸水回缩率为 3. 2%。
目前， 羊毛高支化已成为市场需求的主流， 原因在于产品的高档、 轻薄、 个性化、 柔软、 舒适及易护理等。 而细支（18〜21 μ πι)、 超细支（15〜18 μ ιη)羊 毛是轻薄柔软和舒适无剌痒面料的基础； 低或无毡缩性羊毛及高稳定性定形产 品是面料易护理性能的保证。 因此， 对高品质细支和超细支羊毛的需求日益增 大， 并存在较大缺口， 新型纤维物理细化羊毛纤维满足了细支羊毛的需求， 具 有很大的发展空间。 本发明的化学定型剂与用于羊毛物理细 的化学前处理剂和物理细化设备 有机结合， 可批量生产出具有真丝般光泽羊绒般手感且沸水回缩率低的优质羊 毛物理细化产品。 满足羊毛纤维高支化、 功能化、 羊毛制品轻薄化的市场需求。
