現在越來越多的學校都開始注重整體的形象，基本上現在很多學校都要求穿校服，無論是小學還是大學，但是學校的采購人員每次采購時都不是很了解，哪一種布料比較好，今天就向大家介紹下：園服定制要如何如何選擇面料？
Now more and more schools begin to pay attention to the overall image. Basically, many schools require to wear school uniforms, whether in primary schools or universities, but the school purchasers don't know very well when purchasing each time. Which kind of fabric is better? Today I'll introduce to you: how to choose fabrics for Garden uniform customization?
衛生性
Hygiene
棉纖維是自然纖維，其主要成分是纖維素，還有少量的蠟狀物質和含氮物與果膠質。純棉織物經多方面查驗和實踐，織品與肌膚接觸無任何刺激，無負作用，久穿對人體有益無害，衛生性能良好。
Cotton fiber is a natural fiber. Its main component is cellulose, as well as a small amount of waxy substances, nitrogen-containing substances and pectin. The pure cotton fabric has been inspected and practiced in many aspects. The contact between the fabric and the skin has no stimulation and negative effect. It is beneficial and harmless to the human body for a long time, and has good hygienic performance.

耐熱性
Heat resistance
純棉織品耐熱性能良好，在攝氏110℃以下時，只會引起織物上水分蒸發，不會損傷纖維，所以純棉織物在常溫下，穿著使用，洗滌印染等對織品都無影響，由此對提高了純棉織品耐洗耐穿服用性能。
Pure cotton fabric has good heat resistance. When the temperature is below 110 ℃, it will only cause water evaporation on the fabric and will not damage the fiber. Therefore, the wearing, washing, printing and dyeing of pure cotton fabric at room temperature have no impact on the fabric, which improves the washing, wearing and wearing performance of pure cotton fabric.
吸濕性
Hygroscopicity
棉纖維具有較好的吸濕性，在正常的情況下，纖維可向周圍的大氣中吸收水分，其含水率為高，所以它接觸人的皮膚，使人感到柔軟而不僵硬。如果棉布濕度加大，周圍溫度較高，纖維中含的水分量會全部蒸發散去，使織物保持水平衡狀態，使人感覺舒服。
Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere, and its moisture content is high, so it contacts people's skin and makes people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is high, all the water content in the fiber will evaporate and disperse, so as to keep the fabric in water balance and make people feel comfortable.
耐堿性
Alkali resistance
棉纖維對堿的抵抗能力較大，棉纖維在堿溶液中，纖維不發生破壞現象，該性能有利于服用后對污染的洗滌，清理出雜質，同時也可以對純棉紡織品進行染色、印花及各種工藝加工，以產生更多棉織新品種。
Cotton fiber has great resistance to alkali. When cotton fiber is in alkali solution, the fiber will not be damaged. This performance is conducive to the washing of pollution and the removal of impurities. At the same time, it can also dye, print and process pure cotton textiles, so as to produce more new cotton varieties.
