纺织品检验学复习题First, the noun explanation1,Textiles: general term for textile products that are used for textile or dyeing or reproduction and can be used directly or need further processing・ Productquality: narrow quality (or quality) refers to the characteristics of the product itselfUsability, reliability, safety, environment and service life, etc. Generalized product quality: not only the quality characteristics of the product itself, but also the quality of product design, the quality of raw materials, the quality of measuring instruments, the quality of customer service and other quality requirements2,pre conditioning wet: the sample placed in the relative humidity of 10%~25%, the temperature is not more than 50 degrees Celsius in the atmosphere, after a period of time, so that the sample wet to below the normal moisture recovery process・Humidity control:Standard atmospheric conditions: temperature 20, relative humidity, 101.3kpa・Regain：3,public weight: remove the moisture content of textiles, together with the trade contract or standard weight of moisture・Quality count:Metric count:4,the main grade: according to batch inspection, accounting for 80% and above gradeA heterogeneous fiber; blended with non cotton fibers and unbleached cotton fibers in cottonShag:Cavity hair:A day:Long slub:Long detail:5.Colour fastness: the performance of printing and dyeing textiles in order to retain their original colour and lustreCharneleon card:Dip pattern card:Blue standard:Two. Fill in the blanks1,textile inspection according to the inspection content can be divided into quality inspection, specifications inspection, quantityinspection, weight inspection and packaging inspection.2,The standard atmospheric conditions used in our country are: 20 DEG C, relative humidity 101. 3kpa.3,the basic concept of total quality management is: all in order to prevent the main, all data to speak, everything・4,textile standards in two forms of expression, one is, and the other is.Types of text订e standards include basic technical standards, and.5,There are two main methods to determine the breaking strength of woven fabrics・ One is, and the other is.There are two kinds of methods of clipping woven fabric breaking strength of the sample, and that・6,fabric tearing strength, commonly used methods of determination are single tongue method, and.The main contents include 7 raw cotton, quality inspection, inspection, micronaire, fiber, specific inspection and・ The amount of public inspection including raw cotton impurity rate test, and a bale metric inspection.8. Indication of wool linear density.9 coarse wool is defined as wool fiber with diameter in or above; the cavity hair is defined as long and above the pith cavity, and the widthof the pulp cavity is 1/3 and above the diameter of the fiber・10,according to the classification of raw silk size deviation, and even two degree change, and the five test items in a minimum score to determine the basic level, any lower than the lowest level, as foreign goods・Raw silk appearanee test results according to color, luster, hand to assess, rated as good, ordinary, slightly inferior and grade goods ・11.the quality of combed wool, knitting wool and knitting needles are evaluated in accordance with the test results・ The internal quality is evaluated according to and comprehensive, and the minimum term is determined.

(wool, viscose and polyester of the moisture regains were 16%, 13%, 0.4%)2,measured a batch of 36tex cotton yarn 25cm long twist were 165, 167, 171, 172, 170, and the average twist and twist metric tex system・3,there are a number of homogeneous wool materials, said weight of 5000 kg, measured the actual moisture rate was 14%, and (1) the number of wool conditioned weight; (2) the number of wool scouring, measured the actual oil rate is 1. 2%, the number of public quantity for cleaning hair.4,for a number of homogeneous 2000 kg of wool wool washing, oil extracted from wool grease, measured dry weight of 30 kg, degreased wool dry weight of 2500 kg, and (1) washed wool grease containing rate;(2) the number of wool tops, oil content for top. (the gross moisture regain is 19%)5,take 30 strands of cotton yarn (100m per strand Iong), weigh the total weight of 82. 65g, dry weight of 75. 26g after drying, and requestthe cotton yarn:(1)actual moisture regain;(2)the actual number of Ntex under the determined moisture regain (known as the moisture regain of cotton yarn is 8. 5%)6,the NEP and impurity eye inspection method, calculation formula of the number of neps and impurities in grain 1 grams of cotton yarn in the derivation of the known 13tex; pure cotton yarn, neps and impurities of the total grain number board testing on the test results were 55, 58, 57, 59, 53, 60, 61.62, 67, 65, 72, 74, 75, 7& 69, 7& 67, 77, 7& 75, then the calculation of the yarn neps and impurities in the total grain number・Four, Jane answer1.The principle of measuring the moisture regain of textile materials is briefly described・ The influence of external factors on the accuracy of test results when oven moisture is measured is explained.2.What are the test methods for qualitative identification of textile fibers and the experimental principle and applicability of differential fibers?・3.The principle and applicability of microscopic identification of fibers are reviewed・4.brief description of combed wool classification requirements; combed wool fabric color fastness index which items include?5.cotton gray yarn products and so on, what is the basis for evaluation?6.Explain the inspection index of raw silk quality・7.Brief description of quality inspection items and grading regulations of cotton grey cloth・8.Brief description of the technical requirements and grading regulations of combed wool fabrics・9.The main types of staple fiber products are described, and the quality inspection indexes of polyester staple fiber are listed.10.the classification of raw silk provisions; raw silk main inspection items and grant inspection items・11.The testing principle of capacitive electronic uniformity meter is introduced・12.Briefly describe the principle and operation process of raw silk inclusion test・Five・ Discussion questions1.cotton, wool, silk, viscose and polyester, nylon, spandex fiber color number, please for the identification of their physicochemical examination method.2.The principle of chemical analysis for the determination of fiber content in blended products is described・ How can I determine theblending ratio of polyester / cotton blends, wool / cotton blends, silk / wool blends, cotton / viscose blends?・3.Test methods and determination principle of tensile breaking strength of fabrics・Parallel sampling drawing of tensile fracture strength of woven fabrics ・4.What are the measuring methods for tearing strength of fabrics?
