A consumer laboratory opened an inquiry after a cardigan（开衫）/'kɑːdɪg(ə)n/ labelled pure cashmere（羊绒）/ˈkæʃmɪə/ lost a third of its size in one washing（洗涤）/'wɒʃɪŋ/. The retailer blamed the customer, but auditor Mina Orr found polyester（聚酯纤维）/,pɒlɪ'estə/ fuzz（细绒毛）/fʌz/ and a nylon（尼龙）/'naɪlɒn/ filament（长丝）/'fɪləm(ə)nt/ in the seam. In light of（鉴于）/ɪn laɪt əv/ that evidence, she had to trace the batch rather than（而不是）/ˈrɑːðə ðæn/ treat the shrinkage（缩水）/'ʃrɪŋkɪdʒ/ as an isolated complaint. She stopped the shipment in question（所涉及的）/ɪn ˈkwestʃən/ and requested fibre samples from every production stage.

At the mill, cashmere yarn（纱线）/jɑːn/ should have moved from cleaned fibre through a spindle（纺锭）/'spɪnd(ə)l/ and a fine hackle（梳毛针排）/'hæk(ə)l/. Instead, microscopy showed one synthetic stratum（层）/'strɑːtəm; 'streɪtəm/ beneath a woollen-looking surface. A linear（线性的）/'lɪnɪə/ thread pattern identified the same polyester blend in flannel（法兰绒）/'flæn(ə)l/, tweed（粗花呢）/twiːd/, plaid（格纹布）/plæd/, and ribbed rep（棱纹布）/rep/ samples. Although temperature records plotted against an isotherm（等温线）/ˈaɪsəθɜːm/ ruled out heat damage, the yarn store revealed the substitution. The decisive juncture（环节）/ˈdʒʌŋktʃə/ was there: two unmarked bins had been exchanged.

The error had spread across several clothing lines. Denim（牛仔布）/'denɪm/ dungarees（粗布工装裤）/'dʌŋgə'riz/ were correctly labelled, while a dressy（讲究的）/'dresɪ/ waistcoat（马甲）/'weɪs(t)kəʊt; 'weskɪt/, slacks（便裤）/slæks/ with suspenders（背带）/sə'spendəz/, and silky（丝滑的）/'sɪlkɪ/ pajamas（睡衣裤）/pə'dʒɑːməz/ carried the false cashmere claim. A nightgown（睡袍）/'naɪtgaʊn/, a baby's nappy（尿布）/'næpɪ/, and a teddy（连体内衣）/'tedɪ/ came from another bin and remained accurate. Models clad（穿着……的）/klæd/ in a sarong（纱笼）/sə'rɒŋ/ and rainproof（防雨的）/'reɪnpruːf/ jacket had also been photographed under the wrong description. The catalogue's sartorial（服装方面的）/sɑː'tɔːrɪəl/ language concealed a simple material mismatch.

Home textiles confirmed the boundary of the batch. Drapery（窗帘布）/'dreɪp(ə)rɪ/ and a tablecloth（桌布）/'teɪb(ə)lklɒθ/ contained the synthetic blend, but terry（毛圈布）/'terɪ/ towels and a flannel duster（抹布）/'dʌstə/ did not. A ragged（破旧的）/'rægɪd/ clout（碎布）/klaʊt/ from the cutting table had fallen into tatters（碎条）/'tætəz/ and matched the faulty yarn, while separate sailcloth（帆布）/'seɪlklɒθ/ passed the strength test. Inspectors let each fabric drape（自然垂落）/dreɪp/ over a standard frame and checked whether fluff（松散绒毛）/flʌf/ or fuzz appeared along the edge. Their results matched the bin records rather than the product names.

Finishing records showed how labels had survived later checks. The style check neither tested fabric beneath the braid（编带）/breɪd/ and brooch（胸针）/brəʊtʃ/ nor verified fibre behind an embroidered（刺绣的）/ɪm'brɒɪdə; em-/ mark. A zipper（拉链）/'zɪpə/ and hem（下摆）/hem/ were inspected for alignment, and staff would darn（织补）/dɑːn/ visible holes, yet hosiery（针织袜类）/'həʊzɪərɪ; -ʒərɪ/ tests covered only stretch. In the footwear（鞋类）/'fʊtweə/ room, a cobbler（修鞋匠）/'kɒblə/ and a shoemaker（制鞋匠）/'ʃuːmeɪkə/ checked a sandal（凉鞋）/'sænd(ə)l/, slipper（拖鞋）/'slɪpə/, and hobnail（鞋钉）/'hɒbneɪl/ boot. A bowler（圆顶礼帽）/'bəʊlə/ hat hung on a nearby hanger（衣架）/'hæŋə/, but accessories were outside the affected batch.

At this stage（现阶段）/æt ðɪs steɪdʒ/, Mina ordered relabelling in accordance with（按照）/ɪn əˈkɔːdəns wɪð/ laboratory results. There was no reason to（没有理由做）/nəʊ ˈriːzən tuː/ choose between（在两者之间选择）/tʃuːz bɪˈtwiːn/ refunding buyers and preserving evidence. She told the factory manager, “We can refund buyers now, but we cannot destroy the batch records until the recall closes.” The company did both. It no longer（不再）/nəʊ ˈlɒŋɡə/ sold synthetic cloth under the name of（以……的名义）/ˈʌndə ðə neɪm əv/ cashmere and notified the launderette（自助洗衣店）/,lɔ:ndə'ret, ,lɑ:n-/ that had first reported similar damage. On that basis（据此）/ɒn ðæt ˈbeɪsɪs/, every affected garment was recalled, correctly labelled stock returned to sale, and repeat washing produced no further distortion. The observable result was measurable: complaints stopped and the size test remained stable.
