  The 
  material 
  may 
  be 
  heat 
  treated 
  after 
  or 
  during 
  stretching 
  to 
  affect 
  

   the 
  desired 
  degree 
  of 
  crystallization. 
  It 
  produces 
  monofilament 
  yarns 
  

   of 
  considerable 
  toughness 
  and 
  tensile 
  strength, 
  abrasion 
  resistance, 
  

   and 
  chemical 
  resistance 
  to 
  water, 
  acids, 
  alkalies, 
  and 
  many 
  organic 
  

   solvents. 
  

  

  Little 
  of 
  textile 
  interest 
  was 
  done 
  with 
  these 
  yarns 
  until 
  Mr. 
  Sted- 
  

   man, 
  of 
  Firestone 
  Tire 
  & 
  Kubber 
  Co., 
  Akron, 
  Ohio, 
  took 
  up 
  the 
  

   development 
  and 
  gave 
  the 
  name 
  "Velon" 
  to 
  these 
  products 
  and 
  estab- 
  

   lished 
  the 
  Velon 
  Department. 
  A 
  unit 
  for 
  production 
  was 
  set 
  up 
  at 
  

   the 
  Worldbestos 
  Plant 
  in 
  Paterson, 
  N. 
  J., 
  where 
  monofilament 
  yarns 
  

   are 
  being 
  made 
  as 
  fine 
  as 
  0.007 
  inch 
  in 
  diameter 
  running 
  from 
  10,000 
  

   to 
  12,000 
  yards 
  to 
  the 
  pound. 
  Experiments 
  for 
  the 
  extrusion 
  of 
  

   multifilament 
  yarns 
  are 
  under 
  way 
  and 
  it 
  is 
  expected 
  that 
  yarns 
  as 
  

   fine 
  as 
  100 
  denier 
  can 
  be 
  produced 
  eventually. 
  

  

  At 
  first, 
  flat 
  continuous 
  bands 
  were 
  made 
  to 
  imitate 
  rattan 
  in 
  the 
  

   seat 
  covers 
  of 
  buses 
  and 
  subway 
  cars, 
  and 
  next, 
  shoetop 
  fabrics 
  were 
  

   woven 
  for 
  evening 
  and 
  sport 
  shoes, 
  using 
  the 
  Velon 
  threads 
  as 
  warp 
  

   and 
  cotton 
  yarns 
  for 
  filling. 
  

  

  As 
  soon 
  as 
  round, 
  monofilament 
  yarns 
  of 
  sufficient 
  fineness 
  were 
  

   produced, 
  Mr. 
  Stedman 
  interested 
  August 
  Hafner, 
  president 
  of 
  Haf- 
  

   ner 
  Associates, 
  who 
  is 
  a 
  well-known 
  specialty 
  and 
  experimental 
  weav- 
  

   ing 
  expert 
  in 
  this 
  country, 
  to 
  work 
  out 
  the 
  textile 
  possibilities. 
  Mr 
  

   Hafner 
  could 
  see 
  the 
  potentialities 
  of 
  these 
  yarns 
  at 
  once, 
  and 
  sug- 
  

   gested 
  their 
  use 
  for 
  handbag, 
  trimming, 
  and 
  millinery 
  fabrics 
  of 
  un- 
  

   usual 
  color, 
  design, 
  and 
  weave 
  variations. 
  

  

  Then 
  came 
  the 
  war 
  with 
  its 
  restrictions 
  on 
  copper, 
  steel, 
  aluminum, 
  

   and 
  metals 
  in 
  general. 
  This 
  brought 
  about 
  replacements 
  of 
  metals 
  

   in 
  making 
  mosquito 
  and 
  fly 
  screens. 
  These 
  fly 
  screens 
  are 
  now 
  made 
  

   successfully 
  with 
  vinylidene 
  chloride 
  resin 
  yarns 
  in 
  16 
  by 
  16, 
  12 
  by 
  12, 
  

   and 
  even 
  20 
  by 
  21 
  mesh. 
  Window 
  screens 
  made 
  from 
  this 
  yarn 
  are 
  

   supposed 
  to 
  provide 
  better 
  vision 
  due 
  to 
  their 
  greater 
  transparency. 
  

   At 
  present, 
  it 
  is 
  restricted 
  for 
  civilian 
  use 
  and 
  its 
  application 
  in 
  dress 
  

   goods 
  and 
  wearing 
  apparel 
  will 
  have 
  to 
  await 
  the 
  end 
  of 
  the 
  war. 
  

  

  NEW 
  ELASTIC 
  VINYON 
  E 
  

  

  Late 
  last 
  year, 
  the 
  Vinyon 
  Department 
  of 
  American 
  Viscose 
  Corpo- 
  

   ration 
  in 
  addition 
  to 
  Vinyon 
  filament 
  yarn, 
  explained 
  in 
  my 
  earlier 
  

   paper, 
  offered 
  a 
  new 
  vinyl 
  resin 
  yarn 
  with 
  considerable 
  elastic 
  prop- 
  

   erties 
  known 
  as 
  Vinyon 
  E. 
  It 
  possesses 
  many 
  characteristics 
  of 
  rub- 
  

   ber 
  and 
  opens 
  an 
  entirely 
  new 
  field 
  of 
  applications. 
  For 
  some 
  pur- 
  

   poses 
  it 
  has 
  been 
  found 
  superior 
  to 
  rubber, 
  because 
  it 
  has 
  exhibited 
  

   better 
  resistance 
  to 
  sunlight, 
  tropical 
  heat, 
  and 
  humidity 
  and 
  is 
  not 
  

   affected 
  by 
  body 
  acids. 
  At 
  present 
  it 
  is 
  restricted 
  to 
  military 
  uses, 
  

   where 
  it 
  replaces 
  rubber. 
  However, 
  after 
  the 
  war 
  we 
  will 
  see 
  many
