针织面料尺寸稳定性检测（洗涤后扭斜）分析数据

在生产端，企业以优质区间上限为目标，通过优化纤维配比、定型工艺和后整理技术，控制洗涤后形变，使Sz值趋近上限，打造高端抗变形产品。采购端，采购商根据Sz值对供应商分级，优先选择Sz高的优质供应商，并通过数据谈判降低采购溢价，平衡质量与成本。监管部门则根据行业数据动态调整优质区间，推动标准升级，并通过认证与激励政策引导企业向高性能、可持续方向发展，最终实现全链条的质量提升与市场规范化。一、数据采集：1、采集抽检日期、面料类型、扭斜率（θ）、纵向缩水率（L）、测试干燥方式（Td）等信息；2、利用公式计算综合稳定性指数Sz，Sz = [0.6 (θ基准 /θ) + 0.4 (L基准 / L)] * (10 / K)。
二、数据处理：1、收集全行业面料样本的Sz值，计算均值（μ）、标准差（σ）；2、区间修正，确定优质稳定参考区间，即：[μ+0.5σ, μ+2σ] 。
三、数据应用：行业内企业可根据本公司面料产品尺寸稳定性检测数据，对照上述优质稳定参考区间，确定本公司产品该性能行业内横向比较质量控制水平，若产品Sz值稳定高于或等于区间下限（Sz≥μ+0.5σ），表明纤维含量控制符合行业基础标准。若Sz值≥μ+2σ，代表纤维配比精度行业顶尖，可设为内部质量标杆。进而为企业制定质量管理控制和绩效考核目标提供依据。

On the production side, enterprises take the upper limit of the high-quality range as their target, optimize fiber blending ratios, setting processes and after-finishing technologies to control post-washing deformation, bring the Sz value closer to the upper limit, and develop high-end anti-deformation products. On the procurement side, procurers classify suppliers based on Sz values, prioritize high-quality suppliers with higher Sz values, reduce procurement premiums through data-driven negotiations, and balance quality and cost. Regulatory authorities dynamically adjust the high-quality range based on industry data to promote standard upgrading, guide enterprises towards high-performance and sustainable development through certification and incentive policies, and ultimately achieve full-chain quality improvement and market standardization.

I. Data Collection:
1. Collect information including sampling date, fabric type, torsion slope (θ), longitudinal shrinkage rate (L), test drying method (Td), etc.;
2. Calculate the comprehensive stability index Sz using the formula: Sz = [0.6*(θ_reference / θ) + 0.4*(L_reference / L)] * (10 / K).

II. Data Processing:
1. Collect Sz values of fabric samples across the entire industry, and calculate the mean (μ) and standard deviation (σ);
2. Conduct interval correction to determine the high-quality stability reference interval, which is [μ+0.5σ, μ+2σ].

III. Data Application:
Enterprises in the industry can compare the dimensional stability test data of their own fabric products against the aforementioned high-quality stability reference interval to evaluate their quality control level relative to the industry average for this performance. If the Sz value of a product is consistently greater than or equal to the lower limit of the interval (Sz ≥ μ+0.5σ), it indicates that the fiber content control complies with the basic industry standards. If Sz ≥ μ+2σ, it means the fiber blending precision reaches the industry-leading level, and such products can be set as internal quality benchmarks. This further provides a basis for enterprises to formulate quality management control and performance assessment targets.
