Q1:纱线捻度是什么意思?


捻度 纱丝加捻角扭转一圈为一个捻回。纱线单位长度内的捻回数称捻度。我国棉型纱线采用特数制捻度,即用10 cm纱线长度内的捻回数表示;精梳毛纱和化纤长丝则采用公制支数制捻度,即以每米内的捻回数表示;此外,还有以每英寸内捻回数表示的英制支数制捻度。

捻系数 捻度不能用来比较不同粗细纱线的加捻程度,因为相同捻度,粗的纱条其纤维的倾斜程度大于细的纱条。在实际生产中,常用捻系数来表示纱线的加捻程度。捻系数是结合线密度表示纱线加捻程度的相对数值,可用于比较不同粗细纱线的加捻程度。捻系数可根据纱线的捻度和纱线的线密度计算而得到的。

捻向 捻向是指纱线加捻后,单纱中的纤维或股线中单纱呈现的倾斜方向。它分Z捻和S捻两种。加捻后,纱丝的捻向从右下角倾向左上角,倾斜方向与“S”的中部相一致的称S捻或顺手捻;纱线的捻向从左下角倾向右上角,倾斜方向与“Z”的中部相一致的称Z捻或反手捻。一般单纱常采用Z捻,股线采用S捻。

股线的捻向按先后加捻的捻向来表示。例如,单纱为Z捻、初捻为S捻、复捻为Z捻的股线,其捻向以ZSZ表示。

纱线的捻向对织物的外观和手感影响很大,利用经纬纱的捻向与织物组织相配合,可织出外观、手感等风格各异的织物

    鳄鱼掉" When Branstad was receiving a Chinese trade delegation as Iowa governor in March, he remarked that he would like to be able to enjoy a bite of US beef at the US embassy in Beijing

    落高速The Chinese Navy's hospital ship Peace Ark arrives on Tuesday in Freetown, Sierra Leone, on an eight-day mission to deliver free medical services to 2,000 people in the West African nation后睡The visit marks the first time the ship has visited West Africa, Xinhua said

    鳄鱼掉落高速后睡着 男子执意带回家

    男执[Photo/Xinhua]The Chinese Navy's hospital ship Peace Ark is providing humanitarian medical services to the people of Sierra Leone during an ongoing port call in the West African nation, Chinese media reported意带The vessel arrived on Tuesday in Freetown, Sierra Leone's capital and largest city, which is a major port on the Atlantic Ocean鳄鱼掉A nurse from China draws blood as part of an examination of a boy on the Peace Ark on Sept 21,2017落高速Sierra Leone is the second destination for Peace Ark in its "Harmonious Mission 2017" tour后睡Medical personnel began examining and treating local residents immediately, Xinhua News Agency reported

    男执It carries a total of 115 doctors and nurses, most of them from the People Liberation Army's Naval Medical University and Navy General Hospital意带Each day hundreds of Sierra Leone residents line up outside Peace Ark waiting for their turn to be diagnosed by Chinese doctors, the report said, noting that at least 2,000 residents would receive medical services during the ship's eight-day stay in Freetown鳄鱼掉In return, the United States promised not to use nuclear weapons or conventional weapons to attack or invade the DPRK

    落高速In the statement, the DPRK reaffirmed its commitment to abandoning nuclear weapons and existing nuclear programs后睡"We believe if the parties concerned can adhere to those consensus, abide by the spirit of the joint statement and seek ways to address the reasonable concerns of concerned parties, we will find a way out," said the spokesperson男执Lu said the parties concerned should learn from experience in reaching the agreement, which includes holding that the core of the Korean Peninsula nuclear issue is over security issues, the key lies with the United States and the DPRK, and concerns of all parties should be resolved in a balanced way意带BEIJING -- China said Tuesday that the six-party talks are still an efficient platform to address the Korean Peninsula nuclear issue

    Launched in 2003, the six-party talks were suspended in December 2008Lu said the joint statement, signed on Sept 19, 2005, is the most important progress in addressing the Korean Peninsula nuclear issue through negotiations, and is of milestone significance

    鳄鱼掉落高速后睡着 男子执意带回家

    China also proposed a dual-track approach to denuclearization on the peninsula on the one hand and establishing a peace mechanism on the otherChina has put forward the "double suspension" proposal, which requires the DPRK to suspend its missile and nuclear activities in exchange for the suspension of large-scale US-ROK military drillsThe DPRK walked out of the talks in April 2009 in protest against UN sanctionsAbe, who also heads the LDP, is set to provisionally dissolve the lower chamber of Japan's bicameral system of parliament on Sept 28, as this is when the extraordinary Diet session will be convened, according to LDP sources close to the matter

    However, the prime minister has the authority to dissolve the lower chamber and call a general election at willThis scenario would see official campaigning for the national poll kick off on Oct 10, with voters thereafter casting their ballots on Oct 22A lower house election must be held by December 2018 as this is when the four-year terms of current lower house lawmakers expireIf Abe goes ahead with his plan to call a snap election, then three by-elections that have been slated to take place on Oct 22 would be replaced by the general election

    The opposition camp, however, has criticized Abe's move to call a snap election, with some accusing him of merely trying to escape from the influence-peddling scandals he is currently implicated in and engineering his stay in power"Nikai on Tuesday, during a meeting of ruling LDP executives reportedly conveyed Abe's intentions and relayed the party's determination to get all of its candidates fielded in the race

    鳄鱼掉落高速后睡着 男子执意带回家

    Prior to Abe's departure Monday for a five-day trip to New York to attend the UN General Assembly, Abe told Nikai during a meeting that he "will decide on the timing of the snap election after returning from the UN General Assembly on FridayAbe last dissolved the lower house of parliament in November 2014 and thereafter led the ruling coalition to a sweeping victory in the following election in December

    In addition, the fact that new opposition parties in the process of being formed will not have time to organize themselves and mount a serious challenge to Abe and the LDP in such a short space of time, has made many political watchers question Abe's regard for democracy and the will of the peopleTOKYO - Japanese Prime Minister Shinzo Abe is gearing up to dissolve the lower house of parliament and call a snap general election, Liberal Democratic Party (LDP) Secretary General Toshihiro Nikai confirmed on TuesdayThe support rate for Abe's cabinet has improved moderately recently, and the opposition camp has accused the prime minister of taking advantage of this and have slammed the possible general election as being unnecessary and serving Abe's personal, not political objectivesThe application for UNESCO heritage status submitted by more than 10 groups from China, the Republic of Korea and other countries and regions will "allow the world to fully understand the brutality of the war of agrression, remember history, cherish peace and defend human dignity," Chinese Foreign Ministry spokesperson Lu Kang said at a regular news briefingBEIJING -- Japan should act correctly towards an application for records of comfort women to be listed as UNESCO heritage, instead of threatening not to pay its UNESCO membership fees, a Chinese spokesperson said MondayIf the submitted documents are approved for the UNESCO Memory of the World Register next month, domestic pressure for Japan to cancel payment of its UNESCO membership fees will grow, according to Japanese media

    "The members of international organizations are obliged to pay their membership fees on time and in fullChina demands Japan reflect on its history of aggression, and take a correct attitude towards and do not smear or meddle with the application," Lu said

    The move serves the purposes of the UNESCO, he saidForceful recruitment of comfort women, or sex slaves, was a grave crime committed by the Japanese militarism during WWII

    There is solid evidence and no room for denying that, Lu saidHe said that Japan should handle the issue properly and in a responsible way to gain trust from its Asian neighbors and the international community

    People from the DPRK and the ROK belong to the same ethnic group, and China has always supported the two countries in strengthening exchanges, improving ties and promoting reconciliation, he saidLu's comment came after ROK President Moon Jae-in suggested that his country could go ahead with humanitarian aid to the DPRK "regardless of political situations," despite Japanese Prime Minister Shinzo Abe's request for consideration of the timing of the proposed aidBEIJING -- China hopes that concerned parities can understand and respect the emotions of the people and support normal exchanges between the Democratic People's Republic of Korea (DPRK) and the Republic of Korea (ROK), Foreign Ministry spokesperson Lu Kang said Monday"All the UN Security Council resolutions that imposed sanctions on the DPRK, including the newly adopted Resolution 2375, have stated clearly that they are not intended to have a negative effect on the livelihoods and humanitarian needs of the people there," Lu said at a daily press briefing

    "I think this is not only good for China, but will also be a positive influence to the whole international system," he saidFor example, Singapore can become a launchpad for Chinese companies to march into international markets, and they can make the best of Singapore's trade and service facilities as a financial center and transport hub

    Singapore's cooperation with China concerning the Belt and Road Initiative, Lee said, is focused on infrastructure inter-connectivity, financial projects and third-country programs such as personnel training, which Singapore believes can combine advantages of both sidesThe two sides are expected to exchange views on bilateral ties and issues of common concern, the Chinese Foreign Ministry announced Friday

    In the interview, Lee said the Initiative-related cooperation in sectors such as infrastructure investments, trade and tourism can help further "integrate China into regional and international economic systems while greatly boosting the prosperity and development in other countriesThe Belt and Road Initiative, put forward by Chinese President Xi Jinping in 2013, is aimed at building the Silk Road Economic Belt and the 21st Century Maritime Silk Road through concerted efforts of all related countries to benefit all participants by promoting unimpeded trade, financial integration, infrastructure inter-connectivity and closer people-to-people exchanges

    The Singaporean leader will pay an official visit to China on Sept 19-21 at the invitation of Chinese Premier Li Keqiang"The Initiative will help foster closer cooperation among China and its neighboring countries as well as its trade partners in Europe, Asia and even Africa," he added"We deem the Belt and Road Initiative as positive," Lee said Saturday in an interview with Xinhuanet, Xinhua's official website, noting that China's continuous economic growth has made China an increasingly larger and more important part in the international systemSINGAPORE -- Singaporean Prime Minister Lee Hsien Loong has said that the Belt and Road Initiative of China is positive to the world since it can help further integrate China into regional and international economic systems while boosting growth in other countries

    " In his opinion, the Initiative can help China make more and better contributions to global economic and trade cooperation as well as the international relationsOne option is to hold a snap election on Oct 22, when three by-elections are scheduled, the sources said

    TOKYO - Japanese Prime Minister Shinzo Abe is considering calling a snap election for as early as next month to take advantage of his improved approval ratings and disarray in the main opposition party, government and ruling party sources said on SundayOther possibilities are later in October or after an expected visit by US President Donald Trump in early November

    "Until now, it appeared the election would be next autumn, butAbe's ratings have recovered to 50 percent in some polls
