大家是否發(fā)現(xiàn)過這個一個事項，就是有時候自己買了衣服沒過了幾天就變小了，許多朋友都以為是自己變胖了，幼兒園園服小編來告訴大家其實不是這樣的，接下來小編給大家說一下織物的縮水率。
Have you ever noticed this matter? Sometimes you buy your own clothes and it becomes smaller after a few days. Many friends think you are getting fat. Kindergarten uniform knitting tells you that it is not. Next, let's talk about the shrinkage rate of the fabric.
織物的縮水率是指織物在洗刷或浸水后織物收縮的百分數(shù)。縮水是紡織品在一定狀況經(jīng)過洗刷、脫水、枯燥等進程發(fā)作長度或寬度改變的一種現(xiàn)象。
The shrinkage of fabrics refers to the percentage of shrinkage of fabrics after washing or soaking. Shrinkage is a phenomenon that textiles change in length or width after washing, dehydration and dryness.
縮水程度觸及不同品種的纖維、織物的結構、織物加工時所受之不同外力作用等等。
The shrinkage degree touches on different kinds of fibers, fabric structure, different external forces acting on the fabrics during processing, etc.
縮水率小的是合成纖維及混紡織品，其次是毛織品、麻織品、棉織品居中，絲織品縮水較大，而大的是粘膠纖維、人工棉、人工毛類織物。
The shrinkage of synthetic fibers and blended textiles is the smallest, followed by wool, linen and cotton fabrics in the middle, silk fabrics shrinkage is larger, and the largest is viscose, artificial cotton and artificial wool fabrics.
客觀的講，全棉面料多少都存在著縮水褪色的問題，關鍵是后面的收拾。所以一般家紡的面料都是經(jīng)過預縮處理。值得注意的是經(jīng)過預縮處理不等于不縮水，
Objectively speaking, there is a problem of shrinkage and fading of all cotton fabrics. The key is to clean up the back. Therefore, the fabric of general home textiles is pre shrinking. It is worth noting that shrinkage is not the same as shrinking.
而是指縮水率控制在國標3%~4%以，內衣料尤其是天然纖維的衣料會縮水。因而，在選購衣料時，除了對織物的質量、色澤、花型進行選擇外，對織物的縮水率也應當有所了解。
It means that the shrinkage rate is controlled in the national standard 3%~4%, and the material of underwear materials, especially natural fibers, will shrink. Therefore, when choosing clothes, besides choosing the quality, color and pattern of the fabric, the shrinkage rate of the fabric should also be understood.

1原材料
1 raw materials
織物的原材料不同，縮水率不同。一般來說，吸濕性大的纖維，浸水后纖維脹大，直徑增大，長度縮短，縮水率就大。如有的粘膠纖維吸水率高達13%，而合成纖維織物吸濕性差，其縮水率就小。
The raw materials of fabrics are different, and the shrinkage rate is different. Generally speaking, the fibers with large moisture absorption expand, diameter increases, length shortens and shrinkage rate increases after immersion. For example, the water absorption rate of viscose fiber is as high as 13%, while the moisture absorption of synthetic fabric is poor, and its shrinkage rate is small.
2密度
2 density
織物的密度不同，縮水率也不同。如經(jīng)緯向密度附近，其經(jīng)緯向縮水率也挨近。經(jīng)密度大的織品，經(jīng)向縮水就大，反之，緯密大于經(jīng)密的織品，緯向縮水也就大。
The density of fabric is different and the shrinkage rate is different. If the warp and weft density is near, the longitude and latitude shrinkage also approaches. If the warp density is high, the warp shrinkage will be large. On the contrary, if the weft density is greater than the warp density, the weft shrinkage will be large.
3紗支粗細
3 yarn thickness
織物紗支粗細不同，縮水率也不同。紗支粗的布縮水率就大，紗支細的織物縮水率就小。
Fabric yarn thickness is different, shrinkage rate is also different. The shrinkage of gauze cloth is large, and the shrinkage of gauze is small.

4出產工藝
4 production technology
織物出產工藝不同，縮水率也不同。一般來說，織物在織造和染整進程中，纖維要拉伸屢次，加工時間長，施加張力較大的織物縮水率就大，反之就小。
Fabric production process is different, shrinkage rate is also different. Generally speaking, in the process of weaving and dyeing and finishing, the fibers need to be stretched several times, the processing time is long, the shrinkage rate of the fabric with greater tension is large, and vice versa is small.
5纖維成分
5 fiber composition
天然植物纖維（如棉、麻）和植物再生纖維（如粘膠）與合成纖維（如滌綸、腈綸）比較，簡單吸濕脹大，因而縮水率較大，而羊毛則是因為纖維外表的鱗片結構而簡單氈化，影響其尺度穩(wěn)定性。
Compared with synthetic fibers such as polyester and acrylic fibers, natural plant fibers (such as cotton, hemp) and regenerated plant fibers (such as viscose) have higher water absorption and shrinkage, while wool is simply felted because of its scale structure, which affects its scale stability.
6織物結構
6 fabric structure
一般狀況下，機織物的尺度穩(wěn)定性要優(yōu)于針織物；高密度織物的尺度穩(wěn)定性要優(yōu)于低密度的。在機織物中，一般平紋織物的縮水率小于法蘭絨織物；而針織物中，平針安排的縮水率又小于羅紋織物。
In general, the dimensional stability of woven fabrics is better than that of knitted fabrics, and that of high density fabrics is better than that of low density fabrics. In general, the shrinkage of plain weave fabric is less than that of flannel fabric, while in knitted fabric, the shrinkage of plain knitting arrangement is less than that of rib fabric.
7出產加工
7 production processing
因為織物在染色、印花、后收拾進程中，不可避免的會遭到機器的拉伸，然后有張力存在于織物上。但是織物在遇水后很簡單免除張力，因而咱們會在洗刷后發(fā)現(xiàn)織物縮水。在實踐工藝中，咱們一般用預縮水來處理這個問題。
Because in the process of dyeing, printing and finishing, the fabric will inevitably be stretched by the machine, and then tension exists on the fabric. But the fabric is easy to avoid tension after encountering water, so we will find the fabric shrink after washing. In practice, we usually use pre shrinkage to deal with this problem.
8洗刷護理
8 washing care
洗刷護理包含洗刷、枯燥、熨燙，這三步每一步都會影響到織物的縮水。例如手洗樣品的尺度穩(wěn)定性要優(yōu)于機洗的樣品，而洗刷的溫度同樣會影響其尺度穩(wěn)定性。一般來說，溫度越高，穩(wěn)定性越差。樣品的枯燥方法對織物的縮率影響也是比較大的。
Washing and washing involves washing, boring and ironing. Every step of these three steps will affect the shrinkage of fabric. For example, the scale stability of hand-washed samples is better than that of machine-washed samples, and the temperature of washing also affects the scale stability. Generally speaking, the higher the temperature, the worse the stability. The drying method of sample has a great influence on shrinkage of fabric.
常用的枯燥方法有、滴水枯燥法，金屬網(wǎng)平鋪法，掛干枯燥法和轉筒烘干法。其間滴水枯燥法對織物的尺度影響小，而轉筒拱干法對織物的尺度影響大，其他兩種居中。
The commonly used drying methods are dripping drying, metal mesh spreading, hanging drying and rotary drying. In the meantime, drip drying method has the smallest influence on fabric size, while rotary cylinder arch drying method has the greatest influence on fabric size, the other two are in the middle.
別的，依據(jù)織物的成分選擇一個合適的熨燙溫度，也能夠改進織物的縮水狀況。例如，棉麻織物能夠經(jīng)過高溫熨燙改進其尺度縮率。
In addition, choosing an appropriate ironing temperature according to the composition of the fabric can also improve the shrinkage of the fabric. For example, cotton and linen fabrics can be ironed by high temperature to improve their scale shrinkage.
但并非溫度越高越好，關于合成纖維來說，高溫熨燙非但不能改進它的縮率，反而會對它的功能有所損壞，如面料發(fā)硬發(fā)脆等。
But not the higher the temperature, the better. For synthetic fibers, high temperature ironing can not improve its shrinkage, but damage its function, such as brittle and hard fabrics.
