随着科学技术的高速发展和人们生活水平的不断提高，人们对服装实用功能的要求已不仅仅是蔽体御寒，而是多方面的：从舒适到保健，从安全到卫生，从便于保存和处理到能适合不同的气候和环境，从适合现代人生活节奏到适应现代人的生活方式。特别是近几年来，气候变化无常，气温的日差较大，人们往往因更换服装不及时，而导致诸多疾病的频繁发作，这就对服装的保温和调温功能提出了更高的要求。人体与外界是以热传导、热对流和热辐射等三种形式通过服装向外界传递热量，因此，一般采用能减少热传导、热对流的材料来保温，例如：天然的棉、羊毛、羽绒和它们的仿生材料。但是，这些材料不能全面、高效地阻断热传导、热对流和热辐射。碳化锆纤维具有吸热、蓄热的特性，这种纤维虽有优良的保温性，但无降温和调温的能力。而温控纤维能根据环境变化，在一定温度范围内可自由调节体温，即当环境温度升高时，它可以贮存能量，使人感觉凉爽；当环境温度降低时，它不能释放能量，使人倍感温暖。
1. 保温纤维
碳化锆具有高效吸收可见光，反射红外线的特性，当它吸收占阳光中95%的2um 以下的短波长能源后，通过热转换，可将能源储存在材料中，它还具有反射超过2um 红外线波长的特性。而人体产生的红外线波长约10um 左右，不会向外散发。这说明碳化锆具有理想的吸热、蓄热的特性。若将碳化锆系的化合物微粒与成纤高聚物共混纺制成纤维，吸收在服装内部的热量从人体散发出的热量同时被纤维反射，阻止了热量向外部扩散，起到了高效保温的作用。例如：日本的德桑特公司及尤尼吉卡公司，利用碳化锆为材料，共同开发同了蓄势保温纤维，“太阳能纤维”它是将碳化锆即。先粉碎成!!’以下的超细粒子，然后与高聚物共混后作为芯材，再将此芯材作为皮材的PET 或尼龙进行复合纺丝，制成5.6tex/16.7tex的涤沦或
3.3tex 、7.8tex 的锦纶长丝，即涤纶或锦纶“太阳能纤维”。这种“太阳能纤维”可用来制作滑雪服、防风运动服、暖内衣等，可用保也于农业、装饰、建材等产业领域。
2. 温控纤维
根据环境温度的变化，在一定的温度范围内可自由调节人体温度的温控纤维有相转变物质类、塑性晶体类、添加溶剂类及电发热类等。
2.1相转变物质类温控纤维
利用在室温下能发生相转变的物质，这类物质在相转变时会伴随着吸热和放热现象，通过充填法、浸轧法、微胶囊法，将相变物质处理到纤维或纤维织物中。
2.1.1充填法
将一定长度的中空尼龙纤维束浸在含有相变盐CaCl 2,6H 2O/SrCl2,6H 2O 的水溶液中，然后利用特殊的加工技术将纤维两端封闭，用这种纤维制成的织物由于变相盐在室温下发生结晶和熔融，发生可逆的贮热和释热性，在热循环(30℃）时产生最大的吸热，在冷却循(9℃）时产生明显的放热，从而达到调温的效果。
2.1.2浸轧法
通过传统的浸渍-轧液-预烘-焙烘-水洗工艺，将不同分子里的聚乙醇交联到纤维织物上，形成一层不溶性的相变薄膜，这层薄膜具有显著的热贮存和释放性能。该薄膜会坚牢地附着在织物上，经过数次洗涤，仍能保持这一特性。
2.1.3微胶囊法
用一种能贮存热量并在低温时保持热量的相变物质制成微胶囊加到高聚物溶液中，然后纺丝制成纤维，这种相变物质微胶囊在纤维中起到温控的作用，其保温性能完全不受潮湿环境的
影响。例如：德国制造的温控纤维是用防水的硫酸钠制成的微胶囊并分散在纤维中，升温时，该纤维中硫酸钠会逐渐变成液体，能贮存比水多60倍的能量，当气温降低时，又会逐渐硬化并释放出原来积蓄的热量，调温功能十分显著。
这种纤维可用来制造宇航员的手套、宇航服、家用及工业用纺织品。
2.2塑性晶体类温控纤维
某些塑性晶体在固—固转变时会产生热变化。例如：季戊四醇、2，2—二甲基—1，3丙二醇、2—羧甲基—2—甲基—1，3—丙二醇等，若将它们加入到中空纤维中或用传统的涂层法处理到纤维织物上，可以在不同温度范围内赋予纤维或织物所需的贮热和释热性能。实验证明，用此法改性后的尼龙纤维热含量是改性前的3.5—4倍，改性后的聚丙烯纤维热含量是改性前的2倍。用这种纤维可制造温度在5℃—100℃的温控织物，如绝缘、劳动服装及恶劣气候条件下的动植物保护等。
2.3添加溶剂类温控纤维
某些溶剂在环境温度变化时，具有明显的热胀冷缩性，若将其填封在中空纤维中，可以随温度变化来调节纤维的密度，以达到温控的目的。例如：德国研制成功的一种中空化纤，其中心管道充入一种溶剂和惰性气体，当气温降低时，纤维产生形变，由这种纤维制成的衣服变厚，保温能力增强；当气温上升时，纤维自动恢复原状，通气正常，利于热量的散失。这种温控纤维制成的服装主要用于在野外、室外工作的人员及出外旅游的游客。
2.4电发热温控纤维
将导电的树脂涂覆在纤维或纤维织物的表面，这种纤维或织物通过电流时便会发热，可通过调节电流的大小及织物的编织密度来控制纤维或织物的温度。例如：日本东丽公司使用独特的复合纤维技术，制成一种双层结构的纤维织物，表面涂履导电树脂，织物通过电流即发热，通过调节编织密度，便可自行调节织物温度。这种织物可用于医疗加温的被单、电热地毯、车辆用加温垫等。
保温和温控纤维这种兼具舒适性和功能性的纤维，随着全球气温变化无常，旅游业的迅猛发展及人们对服装舒适性和功能性要求的提高，它将逐渐走向人们的日常生活，特别是对常年在野外、室外工作的地质队员、军人、考古工作者及出外游客等而言，更是迫切需要穿上纤维制成的服装。 Insulation, temperature control fiber and fabrics
This article describes the importance of insulation and temperature control fiber development, and temperature control fiber insulation properties, processing methods and use. Keywords: fiber insulation temperature control along with the rapid development of science and technology and the continuous improvement of people's living standard, the practical function of clothing is not just to cover themselves against the cold, but many: from comfort to health care, security to health, from easy to save and handle to fit different climate and environment, suitable for modern pace of life to adapt to modern lifestyle. Especially in recent years, climate variability, the date of the temperature difference, people tend to be caused by replacement of the clothing is not timely, frequent episodes of many diseases, which put forward higher requirements for clothing insulation and thermostat function. The human body with the outside world is the heat conduction, convection and thermal radiation in three forms to transfer heat to the outside world through the clothing, therefore, generally used to reduce heat conduction, convection material insulation, such as: natural cotton, wool, down and they biomimetic
materials. However, these materials can not be comprehensive, efficient blocking of the heat conduction, convection and radiation. Zirconium carbide fiber with endothermic heat storage characteristics of this fiber has well insulation, but without the ability of cooling and thermostat. T emperature control fiber according to the environmental changes in a certain temperature range, are free to regulate body temperature when the ambient temperature rises, it can store energy, make people feel cool, it can not release energy; when the ambient temperature is reduced, people feel warm.
Insulation fibers with efficient absorption of visible light, reflection infrared properties zirconium carbide, when it absorbs short-wavelength energy accounted for 95% of the sun 2um following thermal conversion, energy storage materials, it also has reflective than 2um infrared the characteristics of the wavelength. Infrared wavelength produced by the body is about 10um, not radiated. This shows that the zirconium carbide ideal endothermic heat storage characteristics. If the Department of zirconium carbide compound particles into the fiber polymer blended into fibers, absorbed in the clothing inside the heat from the body heat from both fiber reflex, to prevent the spread of heat to the outside, played the role of efficient insulation . Example: Japan the De Sangte company and uni Jika companies, the use of zirconium carbide materials, co-developed with a poised insulation fibers, namely "Solar fiber zirconium carbide. First crushed into 'the following ultrafine particles, and then with the polymer blend as the core material, then this core material as the skin material PET or nylon composite spinning, made of polyester of 5.6tex/16.7tex perish or 3.3tex, the 7.8tex nylon filament polyester or nylon "solar fiber". This "solar fiber that can be used to make ski suits, windproof sportswear, warm underwear, available protection in the field of agriculture, decoration, building materials industry . The thermostat fiber according to changes in ambient temperature within a certain temperature range can freely adjust the temperature control of body temperature fiber phase change material class, plastic crystal class, add solvents and electric heating and other. 2.1 thermostat fiber of the phase change material class use the material of the phase transition occurs at room temperature, these substances in the phase transition accompanied by the endothermic and exothermic phenomenon, filling method, dipping method, microencapsulation method, the phase change material processing to the fiber or fabric. 2.1.1 filling method will be a certain length of hollow nylon fiber bundle dip in the aqueous solution containing phase change salt CaCl2 and 6H2O/SrCl2, 6H2O, and then the use of special processing technology closed at both ends of the fibers, made from this fiber fabric disguised form of salt crystallization and melting occurs at room temperature, reversible thermal storage and heat release, thermal cycling (30 °
C) maximum endothermic cooling through (9 ° C) produced a significant exothermic, and thus the effect of the thermostat.
1.2 Padding by conventional impregnation - Rolling fluid - pre-baking - baking - washing process, different molecules in the PEG cross-linked to the fabric,
forming a layer of insoluble phase change film, this layer films have a significant heat storage and release properties. The film will fastness attached to the fabric, after repeated washing, and still maintain this feature. 2.1.3 microcapsules with a storage of heat and retain heat in the low temperature phase change material made of micro-capsules added to the polymer solution, and then spinning into fibers, such a phase change material microcapsules in the fiber played the role of temperature control, thermal insulation properties not subject to humid environments. For example: German-made temperature control fiber is made of water resistant sodium sulfate microcapsules and dispersed in the fiber, when the temperature of the fiber, sodium sulfate will gradually become liquid, can store water more than 60 times the energy, when when the temperature is lower, will gradually hardening and release the heat of the original savings, the thermostat function is very significant.
This fiber can be used to manufacture gloves of astronauts, space suits, household and industrial textiles. 2.2 plastic crystal class thermostat fiber plastic crystals in the solid - solid transition will produce thermal changes. For example: pentaerythritol, 2,2 - dimethyl-1 ,3-propanediol, 2 - carboxymethyl - 2 - methyl-1 ,3 - propylene glycol, etc. If they are added to the hollow fiber or using traditional coating treatment to the fabric, can be given in the temperature range for thermal storage and heat release properties of the fiber or fabric required. Experiments show that this method modified nylon fiber heat content is 3.5-4 times the pre-modified, modified polypropylene fiber heat content is two times before the modification. This fiber can produce a temperature of 5 ℃ and -100 ℃ temperature control fabrics, insulation, such as labor clothing and weather conditions, flora and fauna protection. 2.3 add some solvent of the solvent temperature control fiber, with a significant thermal expansion and contraction in the ambient temperature changes, if its filling up the hollow fiber, the fiber density varies with temperature to regulate the temperature control in order to achieve purpose. For example: Germany developed a hollow chemical fiber, the center pipe filling into a solvent and an inert gas, when the temperature decreases, fiber distortion in clothes made from this fiber thickening the insulation ability; when the temperature is increased , the fibers of restitution, normal ventilation is conducive to heat loss. This temperature control fiber clothing is mainly used in the field, outdoor work, workers and tourists to travel abroad. 2.4 electric heating thermostat fiber conductive resin-coated surface of the fiber or fabric, such fiber or fabric through the current will heat the temperature of the fiber or fabric, can be controlled by regulating the current size and fabric weave density . : T oray , Japan uses a unique composite fiber technology made a two-layer structure of the fabric, coated with shoe conductive resin, fabric by the current, fever, and can adjust itself to the fabric temperature by adjusting the weave density. The fabric can be used for medical heating blankets, electric carpets, vehicles, heating pad.
This insulation and temperature control fiber combines comfort and
functionality of the fiber, as global temperatures fickle, the rapid development of tourism and the improvement of clothing comfort and functionality requirements, it will gradually become the people's daily lives , is a perennial in the wild, outdoor geological player, soldier, archaeologists and go out to tourists, is an urgent need to put on the clothing fibers.
